What formula would you use to find 50 is what percent of 20?
a) p = rb
b) r = p/b
c) i = prt
d) b = p/r
We would use r = p/b formula to find 50 is what percent of 20.
The correct answer is an option (b)
For given question,
we need to find the formula which we use to find 50 is what percent of 20
We make the assumption that 20 is 100% since it is our output value.
Let the value we seek be m.
So, 100 % = 20 ...............(1)
m % = 50 ..............(2)
By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
[tex]\frac{100\%}{m\%}=\frac{2}{5}[/tex]
So, m = 250%
This means, 50 is 250% of 20
The formula PERCENTAGE p = rb – The result obtained when a number is multiplied by a percent.
The formula BASE ( b = p/r) – The whole in a problem. The amount you are taking a percent of.
The formula RATE (r = p/b) – The ratio of amount to the base. It is written as a percent.
Therefore, we would use r = p/b formula to find 50 is what percent of 20.
The correct answer is an option (b)

If m<4=119, what is m<10
Answer: So after applying concept of parallelism m<10 = 119
Step-by-step explanation:
As we have given m<119
In terms of parallelism
m< 4 = m<8
and m<8 = m<10
Therefore
m< 10 = m<4 = 119
So after applying concept we get m<10 = 119.

Answer: GEF = 30 DEF = 40
Step-by-step explanation: By angle summation we know the entire angle
GED = 70, so the smaller angles that make up GED (GEF and DEF) will have to sum up to equal GED. Using this we get:
2x + 10 + 5x - 10 = 70
From here we can combine like terms:
7x = 70
and solve for x
x = 10
Then we can plug the value of x back into the equations given to solve for GEF and DEF
GEF:
2x+10 == 2(10)+10 = 30
DEF:
5x-10 == 5(10)-10 = 40
The length of a rectangle is 6 more than its width. The perimeter of the rectangle is 60 feet. If w is the width of the rectangle, which expression represents the length? w+5 w-5 5w 1/5w
The length expression is 6 + w
How to determine the length expression?The given parameters are:
Length =6 more than the width
Width = w
Perimeter = 60
Subsitute Width = w in Length =6 more than the width
This gives
Length =6 more than the w
More than mean +
So, we have
Length = 6 + w

Average is the ratio of the total value divided by the number of observation used.
Given,
In 2008, the centers for disease control and prevention reported the average human life span in the united states as 76.8 years for men and 81.6 years for women.
Here we need to calculate how much longer, on average, u.s. women live than men in seconds.
Here we know that,
Average life span for men = 76.8 years
Average life span for women = 81.6 years.
So, the women lived
=> 81.6 - 76.8
=> 4.8 years.
So, the average women lived 4.8 years more than the man.
Now we have to convert it into seconds,
We know that,

Given that data:
x : 7, 5, 11, 8, 14, 19, 16, 15, 13, 27

Which value of x makes the equation 3.5(x+20)=6+.75(x+1) true?
Answer:
x = -23
Step-by-step explanation:
3.5(x+20) = 6 + .75(x + 1) Multiply the terms inside the parentheses on the left by 3.5 and the parentheses on the left by .75
(3.5)x +(3.5)(20) = 6 + (.75)x +(.75)(1)
3.5x + 70 = 6 + .75x + .75 Combine the 6 and .75 on the right side
3.5x + 70 = 6.75 + .75x Subtract .75x from both sides of the equation
2.75x + 70 = 6.75 Subtract 70 from both sides of the equation
2.75x = -63.25 Divide both sides by 2.75
x = -23
Check
3.5(-23+20) = 6 + .75(-23 + 1)
3.5(-3) = 6 +.75(-22)
-10.5 = 6 +(-16.5)
-10.5 = -10.5
Answer:
x = -23
Step-by-step explanation:
3.5(x+20)=6+.75(x+1)
3.5x + 70 = 6 + .75x + .75
3.5x+70=.75x+6.75

A rectangular sheet of tin measures 20 inches by 12 inches. suppose you cut a square out of each corner and fold up the sides to make an open-topped box. what size square should you cut out to maximize the box's volume? show all work to earn credit.
The volume of the box is maximized when a 6 x 6 inch or 10 x 10 inch square is cut from the corners of the rectangular sheet.
Volume of rectangle:
The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units.
The formula for Volume of the rectangle is
V = l x b x h
where
l represents the length
b represents the breadth
h represents the height.
Given,
A rectangular sheet of tin measures 20 inches by 12 inches. suppose you cut a square out of each corner and fold up the sides to make an open-topped box.
Here we need to find the volume of the box is maximized when a square is cut from the corners of the rectangular sheet.
Here we have the following values:
h = x
l = 20 - 2x
b = 12 - 2x.
Here we have to subtract two times of x value because in the question they said that we have to cut a square from it.
Apply the values on the volume formula then we get,
=> V = (20 - 2x) x (12 - 2x) x (x)
=> V = [240 - 40x - 24x + 4x²] x (x)
=> V = [240x - 64x² + 4x³]
Now differentiate:
=> V' = 240 - 64x + 4x²
Simplify and order the equation,
Then we get,
=> V' = x² - 16x + 60
When we factorize the equation then we get,
=> V' = x² - 6x - 10x + 60
Take the common term out of it,
=> V' = x (x-6) -10(x -6)
Therefore, the value of x is, either 6 or 10.
Now you need to look at your solutions.
At x=6, the volume is,
=> V = (20 - 2(6)) x (12 - 2(6)) x (6)
=> V = (20 - 12) x (12 - 12) x 6
=> V = 8 x 0 x 6
=> V = 0
our corner squares devour the entire piece of cardboard and you are left with zero volume; so that solution is a minimum.
Now at the value of x = 10,
The volume is
=> V = (20 - 2(10) x (12 - 2(10)) x (10)
=> V = (20 - 20) x (12 - 20) x 10
=> V = 0 x (-8) x 10
=> V = 0
So, in both cases we have 0 as minimum volume. So, we can take any one of the value to get the maximum out of it.

Say that you own property with a market price of $74,000. the state tax assessors have given it an assessed value of 48% of that amount. if your state’s property tax rate is 0.031, how much do you owe in property tax, to the nearest dollar? a. $1,101 b. $2,294 c. $35,520 d. $1,193 please select the best answer from the choices provided a b c d
Option a. $1101 is the amount one owes in property tax
The market price of the property = $74000
The assessed value of the property as per the state tax assessors= 48%
So, assessed value in terms of dollars = (48/100)*74000 = $35520
Property tax is calculated on the assessed value of the property. Therefore we will calculate the property tax as follows:
Property tax rate in the state= 3.1%
So, property tax on the owned property will be = (3.1/100)*35520 = 1101.12 or 1101
Therefore, option a. $1101 is the correct answer for the given question
Hence, one needs to pay $1101 in property tax to the state

6?
A. 10
B. 15
C. 21
D. 25
Answer:
C. 21
Step-by-step explanation:
5 times of x is 5x.
5x + 10 = 35
Remove 10 from both sides to get one side x, and the other side a number.
5x + 10 - 10 = 35 - 10
5x = 25
Both sides of the equation can be divided by 5.
x = 5
3 times of x is 3x.
3x + 6
Substitute in x = 5 from the earlier working.
3(5) + 6
= 15 + 6
= 21
Therefore, the result of 3 times x added to 6 is 21.
