There are a total of 39 students in fourth grade at school this year. Today, some of the fourth graders have gone on a field trip to be exact 3/4 of the women went and 2/3 of the men went. This leaves 11 fourth graders at the school. How many women and how many men are in fourth grade at your school this year?
Solving a system of equations we wll see that there are are 24 women, and the other 15 students are men in foruth grade.
How many women and men are in fourth grade?We know that there are 39 students in fourth grade, we know that:
3/4 of the women went
2/3 of the men went
And this leaves 11 students at the school, then we can write the equation:
(3/4)*W + (2/3)*M + 11 = 39
Where W and M are the number of women and men respectively.
(3/4)*W + (2/3)*M = 39 - 11 = 28
(3/4)*W + (2/3)*M = 28
And we also know that the total number is 39, then:
M + W = 39
So we can write the system of equations:
(3/4)*W + (2/3)*M = 28
M + W = 39
M = 39 - W
REplacing that on the other equation we get:
(3/4)*W + (2/3)*(39 - W) = 28
(3/4)*W - (2/3)*w + 26 = 28
(3/4)*W - (2/3)*W = 28 - 26 = 2
(9/12)*W - (8/12)*W = 2
(1/12)*W = 2
W = 2*12 = 24
There are 24 women, and the other 15 students are men.

Canceling common factors and evaluating the limit, we can finally conclude that the velocity of the ball at t = 2 is as follows. v(2) = lim (-160 + 17)(t - 2) t-2 t2 lim (-160 + 17] t2 = -16 + 17 =
The velocity of the ball at t = 2 is 1 m/s.
To calculate the velocity of a ball at a certain time, we can use the following formula:
[tex]v(t) = lim (F(t) - F(t0)) / (t - t0)[/tex]
where F(t) is the position of the ball at time t, and t0 is the starting time. In this example, we are trying to find the velocity of the ball at t = 2, so t0 = 0. Substituting these values into the equation, we get:
[tex]v(2) = lim (F(2) - F(0)) / (2 - 0)[/tex]
F(2) is the position of the ball at time 2, which is given as -160 + 17t. Plugging this into the equation, we get:
[tex]v(2) = lim (-160 + 17t - 0) / (2 - 0)[/tex]
We can simplify this equation by canceling out the common factors and evaluating the limit, which gives us:
[tex]v(2) = lim (-160 + 17)(t - 2) / (t - 2)[/tex]
Canceling the common factors, we get:
[tex]v(2) = lim (-160 + 17) / 1[/tex]
Finally, evaluating the limit, we get the velocity of the ball at t = 2:
[tex]v(2) = -160 + 17 = -16 + 17 = 1 m/s[/tex]

2. The national average utility cost is $236.24 per month. If the average electric bill is 38% the total
amount and the average utility cost for Tolleson, AZ is $192.40, what would be the cost of a typical
Tolleson electric bill and how would that compare with the national average? How much lower is
Tolleson's average compared to the national average?
Answer:To find the cost of a typical Tolleson electric bill, we need to calculate what portion of the total average utility cost is for electricity. If the average electric bill is 38% of the total amount, we can multiply the total average utility cost in Tolleson by 0.38:
$192.40 * 0.38 = $72.90
So the cost of a typical Tolleson electric bill is $72.90.
To compare Tolleson's electric bill cost with the national average, we can subtract the national average from Tolleson's average:
$236.24 - $72.90 = $163.34
So the national average is $163.34 higher than Tolleson's average electric bill cost.
Therefore, Tolleson's average electric bill cost is lower than the national average by $163.34.

What system of inequalities is shown by each graph?
The system of inequalities is shown by each graph are;
y ≤ 0.5x - 4 and y < -2x + 0
How to interpret Inequality Graphs?An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
From the given graph, the y-intercept of the solid line is y = -4.
The slope is gotten as; m = (0 - (-4))/(8 - 0)

there is no difference in the values of Time for Idil or Sophie in that their amount will be tripled.
What is compound interest?The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, which is the formula for compound interest.
Given, Idil invested $150 in an account paying an interest rate of 5.785% compounded annually. Sophie invested $150 in an account paying an interest rate of 5.625% compounded continuously.
From the general formula of compound interest:
Final value A = (1 + r/n)^nt,
where P is the principal balance
r is the interest rate
n is the number of times interest is compounded annually
t is the number of years,
For Idil,
P = 150, r = 5.782, A = 3*p = 450, and n = 1
Thus,
450 = 150 (1 + 5.785%)^t
3 = (1.05785)^t
t = 19.535 years
The time required to get a total amount of $450.00 with compounded interest on a principal of $150.00 at an interest rate of 5.785% per year and compounded 1 time per year is 19.535 years.
(about 19 years 6 months)
For Sophie,
P = 150, r = 5.625, A = 3*p = 450
First, convert R as a percent to r as a decimal
r = R/100
r = 5.625/100
r = 0.05625 per year,
Then, solve the equation for t
t = ln(A/P) / r
t = ln(450.00/150.00) / 0.05625
t = 19.531 years
The time required to get a total amount of $450.00 with compounded interest on a principal of $150.00 at an interest rate of 5.625% per year and compounded continuously is 19.531 years.

3/4of a cup of mixed berries for each batch of muffins, how many batches can he make?
The number of batches of muffins she can make will be 5.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other features.
Clayton picks two times as many raspberries and 11/4 cups of blackberries at a berry farm. He brings the berries home and makes mixed-berry muffins with them.
The number of the batches of muffins can be calculated as:-
Number = ( 1¹/₄ + 2 x 1 ¹/₄ ) / ( 3 / 4 )
Number = [ ( 5 / 4 ) + ( 5 / 2 ) ] / ( 3 / 4 )
Number = [ ( 15 / 4 ) / ( 3 / 4 ) ]
Number = 5
Therefore, the number of batches of muffins will be 5.

3(2x+11) and (3c+15)(2) equivalent
Step-by-step explanation:
3(2x+11)=(3c+15)(2)
6x+33=6c+30
6c-6x=30-33
6c-6x=3
6c=3-6x
3(3-6x)+33=6(3-6x)+30
9-18x+33=18-36x+30
24-18x=12-36x
-18x=-12
x=4/6
6(4/6)+33=(3c+15)(2)
4+33=6c+30
37-30=6c
7/6=c
The expressions 3(2x + 11) and (3c + 15)(2) are not equivalent, as they are different when they are simplified the most.
What are equivalent expressions?Equivalent expressions are expressions that are simplified to the same expression.
The first expression is simplified applying the distributive property as follows:
3(2x + 11) = 6x + 33.
The second expression is also simplified applying the distributive property as follows:
(3c + 15) x 2 = 2(3c + 15) = 6c + 30.
Different expressions, due to different variables (x and c) and constants (33 and 30), hence they are not equivalent.
