Let's call the two-digit number "x" and its two digits "a" and "b".
We know that:
x = 5 * (a + b)
We also know that the reverse of x is 9 times greater than x:
x + 9 * x = 100 * a + 10 * b
Expanding x using the first equation:
10 * x = 5 * (a + b) + 9 * 5 * (a + b) = 100 * a + 10 * b
Combining like terms:
10 * x = 100 * a + 10 * b
Solving for x:
x = 10 * a + b
Since x is a two-digit number, 10 * a + b must be between 10 and 99. The only solution that meets this requirement is a = 5 and b = 6. Therefore, the number is 56.

3x + 6 is equivalent to 9x
Step-by-step explanation:
false.
3x + 6x is equivalent to 9x
but not 3x + 6. 6 is a constant added term. not a multiplication factor. so, it cannot be combined with a multiplication factor.
but 3x + 6 = 9x
has one solution, one value of x for which this equation is true :
3x + 6 = 9x
6 = 6x
x = 1
so, for x = 1 (and only for x = 1) this is true. for any other value of x this is false.
therefore, the general equivalent statement is false.

a gray squirrel population was introduced in a certain region 27 years ago. biologists observe that the population doubles every nine years, and now the population is 680. (a) what was the initial squirrel population? squirrels (b) what is the expected squirrel population, p, t years after introduction? p(t)
The gray squirrel population t years after introduction is P(t) = [tex]340 x 2^(t/9).[/tex]
The formula for the gray squirrel population, p, t years after the introduction of the population is [tex]P(t) = P0 x 2^(t/9)[/tex], where P0 is the initial population. We can use this formula to answer both (a) and (b). For (a), we can substitute t = 0 and P(t) = 680, to solve for P0. This gives us that the initial population of gray squirrels was 340. For (b), we can substitute t = 27 (the number of years since introduction) and P(t) = 680, to solve for P(27). This gives us that the expected population of gray squirrels t years after introduction is 1360. Therefore, the formula for the gray squirrel population t years after introduction is [tex]P(t) = 340 x 2^(t/9)[/tex].

10 meters into the pool, the depth of the water is 2 meters. how deep is the water 38 meters into the pool?
At 38 meters into the pool, the water is 7.6 meters deep. Water depth is the distance in feet between the ocean's surface and bottom, as determined by mean lower low water.
Ocean depth is most frequently and quickly measured using sound. Sonar, which stands for sound navigation and range, is a technique that allows ships to map the topography of the ocean below. The instrument uses sound waves to send to the ocean's bottom and time how long it takes for an echo to come back. The straightforward formula "d/2 = vt" is used to determine the depth "d" because the speed of sound in water is known.
height-1 = 10
height-2 = 38
depth-1=2 m
depth-2 = ?
depth-2 = (height 2* depth 1)/height 1
depth-2 = ( 38*2)/10
depth-2 = 7.6 m

Kendall has only quarters and dimes in her pocket. The total value of these coins is $1.50. The equation below can be used to find q, the number quarters, and d, the number of dimes in her pocket. If Kendall has 4 quarters in her pocket, how many dimes are in her pocket? 25g + 10d = 150
Answer:
Kendall must have 5 dimes in her pocket.
Step-by-step explanation:
First, let's write down all the information that is given to us:
q = number of quarters ["q, the number quarters"]
d = number of dimes ["d, the number of dimes"]
q = 4 ["Kendall has 4 quarters in her pocket"]
25q + 10d = 150
Since the value of q is given to us, our equation now has one unknown variable, d, and we can solve for it.
25q + 10d = 150 [Plug in q]
25(4) + 10d = 150 [Simplify]
100 + 10d = 150 [Subtract 100 from both sides]
10d = 50 [Divide both sides by 10]
d = 5
So, since d=5, Kendall must have 5 dimes in her pocket.

a developmental psychologist studies the number of words that seven infants have learned at a particular age. the numbers are 10, 12, 8, 0, 3, 40, and 18. figure the (a) mean, (b) median, and (c) standard deviation for the number of words learned by these seven infants. (d) explain what you have done and what the results mean to a person who has never had a course in statistics
The mean of 13 words, median of 10 words, and standard deviation of 13.20 words give us an idea of the central tendency and variability of the number of words learned by the seven infants.
(a) Mean: The mean is the average of the values and can be calculated by adding all the values and dividing by the number of values. For the number of words learned by the seven infants, the mean can be calculated as follows:
mean = (10 + 12 + 8 + 0 + 3 + 40 + 18) / 7 = 91 / 7 = 13
So the mean number of words learned by the seven infants is 13 words.
(b) Median: The median is the middle value in a set of values. If the number of values is odd, the median is the middle value. If the number of values is even, the median is the average of the two middle values.
0, 3, 8, 10, 12, 18, 40
The median is 10 words.
(c) Standard Deviation: The standard deviation is a measure of the spread or variability of a set of values.
First, the deviations from the mean are calculated as follows:
10 - 13 = -3
12 - 13 = -1
8 - 13 = -5
0 - 13 = -13
3 - 13 = -10
40 - 13 = 27
18 - 13 = 5
Next, the squared deviations are calculated:
(-3)^2 = 9
(-1)^2 = 1
(-5)^2 = 25
(-13)^2 = 169
(-10)^2 = 100
27^2 = 729
5^2 = 25
The variance is then calculated as the average of the squared deviations, divided by the number of values (n - 1):
variance = (9 + 1 + 25 + 169 + 100 + 729 + 25) / (7 - 1) = 1058 / 6 = 176.33
Finally, the standard deviation is calculated as the square root of the variance:
standard deviation = sqrt(variance) = sqrt(176.33) = 13.20
(d) Explanation: The mean, median, and standard deviation are measures of the central tendency and variability of a set of values. The mean is the average of the values and gives an idea of the typical value.
In this case, The mean tells us that the typical number of words learned by the seven infants is 13 words, the median tells us that half of the infants learned more than 10 words and half of the infants learned less, and the standard deviation tells us that the values are spread out around the mean with a deviation of about 13 words.

Use trigonometric identities to solve each equation within the given domain.
a) –sin2(x) = cos(2x) from [–π, π]
b) 3 tan(x) = 2 sin(2x) from [0, 2π)
c) sec(x) cos(3x) = 0 from [–π/2 ,π/2]
d) 1 – cos(x) = 2 – 2 sin^2(x) from (–π, π)
e) 4cos^4 (x) – 5cos^2(x) + 1 = 0 from [0, 2π)
if you answer all thank you so much this helps a lot!
Step-by-step explanation:
a)
-sin(2x) = cos(2x)
sin(2x) = cos(2x)
2sin(x)cos(x) = cos(2x)
2sin(x)cos(x) = 1 or -1
sin(x) = +/-√(1/2) or sin(x) = 0
x = (2n+1)π/4 or x = nπ
b)
3 tan(x) = 2 sin(2x)
tan(x) = 2/3 sin(2x)
sin(2x) = 3 tan(x)/2
cos^2(x) = (1 - sin^2(x)) = (1 - (3 tan(x)/2)^2)/4
x = nπ/2 + arctan(2√(2)/3) or x = nπ/2 + arctan(-2√(2)/3)
c)
sec(x) cos(3x) = 0
cos(x) = 0 or cos(3x) = 0
x = nπ/2 or x = (3n+1)π/6
d)
1 - cos(x) = 2 - 2sin^2(x)
cos(x) = 2sin^2(x) - 1
2sin^2(x) = cos(x) + 1
sin^2(x) = (cos(x) + 1)/2
sin(x) = +/- √((cos(x) + 1)/2)
e)
4cos^4(x) - 5cos^2(x) + 1 = 0
cos^2(x) = (1 ± √(5))/2
x = arccos(±√((1 + √(5))/2)) or x = arccos(±√((1 - √(5))/2))

12. A tall shelf has 80 books. The ratio of fiction to nonfiction to a general reference to
children’s books is 6: 5: 2: 3, respectively. How many more children’s books are
there than general reference books?
1 Let's call the two numbers x and y. According to the ratio, x:y = 8:9, so y = (9/8)x. And since their sum is 136, x + y = 136, so we can substitute y = (9/8)x into this equation:
x + (9/8)x = 136
(17/8)x = 136
x = 64
So the two numbers are 64 and 72.
2 Let's call the three numbers x, y, and z. According to the ratio, x:y:z = 3:2:7, so y = (2/3)x and z = (7/3)x. And since their sum is 108, x + y + z = 108, so we can substitute y = (2/3)x and z = (7/3)x into this equation:
x + (2/3)x + (7/3)x = 108
(12/3)x = 108
x = 36
So the three numbers are 36, 24, and 84.
3 Let's call the four numbers a, b, c, and d. According to the ratio, a:b:c:d = 5:6:7:8, so b = (6/5)a, c = (7/5)a, and d = (8/5)a. And since the greatest of these is 24, d = 24, so we can substitute c = (7/5)a and d = (8/5)a into this equation:
a + (6/5)a + (7/5)a + (8/5)a = 24
(27/5)a = 24
a = 24 * 5/27 = 8
So the four numbers are 8, 9.6, 10.4, and 24. And the sum of these numbers is 8 + 9.6 + 10.4 + 24 = 52
4 Let's call the three heirs' land area x, y, and z. Since the eldest heir received three times as much as the youngest child, who received two times as much as the middle child, we can write the equation:
x = 3y and y = 2z
So we can substitute y = 2z into x = 3y to get:
x = 3 * 2z = 6z
And since the middle child received 12 ha of land, we can substitute z = 12 into x = 6z to get:
x = 6 * 12 = 72
So the total area of land they inherited is x + y + z = 72 + 2 * 12 = 96 ha.
5 Let's call the two numbers x and y. According to the ratio, x:y = 4:5, so y = (5/4)x. And since their sum is 108, x + y = 108, so we can substitute y = (5/4)x into this equation:
x + (5/4)x = 108
(9/4)x = 108
x = 36
So the two numbers are 36 and 45.
6 Let's call the three numbers x, y, and z. Then, we have:
x:y:z = 6:7:8
x + y + z = 63
To find the values of x, y, and z, we can use the first ratio to write x, y, and z as multiples of the same number. Let's call that number t:
x = 6t
y = 7t
z = 8t
We can use the second equation to solve for t:
6t + 7t + 8t = 63
21t = 63
t = 3
So, the three numbers are:
x = 6t = 6 * 3 = 18
y = 7t = 7 * 3 = 21
z = 8t = 8 * 3 = 24
7 Let's call the three numbers a, b, and c. Then, we have:
a:b:c = 2:3:5
a = 48 (the least of these)
To find the values of b and c, we can use the first ratio to write b and c as multiples of a:
b = 3a = 3 * 48 = 144
c = 5a = 5 * 48 = 240
8 Let's call the three numbers p, q, and r. Then, we have:
p:q:r = 3:5:7
r = 75 (the greatest of these)
To find the values of p and q, we can use the first ratio to write p and q as multiples of r:
p = 3r/5 = 3 * 75/5 = 45
q = 5r/7 = 5 * 75/7 = 50
9 Let's call the number of male students m and the number of female students f. Then, we have:
m:f = 2:3
m + f = 50
To find the values of m and f, we can use the first ratio to write m and f as multiples of the same number. Let's call that number t:
m = 2t
f = 3t
We can use the second equation to solve for t:
2t + 3t = 50
5t = 50
t = 10
So, the number of male students is:
m = 2t = 2 * 10 = 20
And the number of female students is:
f = 3t = 3 * 10 = 30
10 Let's call the number of stamps that Cherie has x, the number of stamps that Mona has y, and the number of stamps that Kate has z. Then, we have:
x:y:z = 3:4:5
x + y + z = 360
To find the values of x, y, and z, we can use the first ratio to write x, y, and z as multiples of the same number. Let's call that number t:
x = 3t
y = 4t
z = 5t
We can use the second equation to solve for t:
3t + 4t + 5t = 360
12t = 360
t = 30
So, Cherie has:
x = 3t = 3 * 30 = 90 stamps
Mona has:
y = 4t = 4 * 30 = 120 stamps
Kate has:
z = 5t = 5 * 30 = 150 stamps
11 The marbles are divided in the ratio 1:2:2:3, so there are 2 x 2 = 4 times as many yellow and blue marbles as there are red marbles. Therefore, there are 2 + 2 = 4 red marbles. Hence, there are 4 x 2 = 8 yellow and blue marbles. Furthermore, there are 3 times as many green marbles as there are red marbles, meaning there are 3 x 4 = 12 green marbles. Therefore, the total number of yellow and green marbles is 8 + 12 = 20.
12 According to the ratio, there are 6:5:2:3 of fiction to nonfiction to general reference to children's books. So the number of each category can be calculated as follows:
Fiction: 6/16 x 80 = 30 books
Nonfiction: 5/16 x 80 = 25 books
General reference: 2/16 x 80 = 10 books
Children's books: 3/16 x 80 = 15 books
So, there are 15 - 10 = 5 more children's books than general reference books.

timmy and susie both work at the Monster Burger. Timmy works for 40 hours and makes 720 dollars. He has been working there longer than susie who makes only 600 dollars in the same amount of time. Monster Burger employees are given a 50 cent raise a year.
Answer:
Timmy has been working at Monster Burger longer than Susie, which explains why he earns more money. Monster Burger employees are given a 50 cent raise each year, so Susie's salary will likely increase over time as she continues to work there.
Step-by-step explanation:
It is possible to determine how long Susie has been working at Monster Burger by using the information given. Since Timmy makes 720 dollars working 40 hours and Susie makes 600 dollars working the same hours, we can calculate their hourly wages:
Timmy's hourly wage: 720 / 40 = 18 dollars
Susie's hourly wage: 600 / 40 = 15 dollars
Since Monster Burger employees are given a 50 cent raise a year, this means that Susie's hourly wage has increased by 50 cents * x years, where x is the number of years Susie has been working there. Thus, we have:
15 + (0.50 * x) = 18
Solving for x, we get:
x = (18 - 15) / 0.50 = 6 years
Therefore, Susie has been working at Monster Burger for 6 years.
