Answer:
280 men; 80 women.
Step-by-step explanation:
this task can be solved used system of two equation (note, it is not the only and shortest way):
1) if number of men is 'm', women is 'w' and ratio is 7:2, then it is possible to write the first equation: m/w=7/2;
if together there are 360, then it is possible to write the second equation of the system: m+w=360.
2) after item 1 it is possible to make up and solve the system:
[tex]\left \{ {{m/w=7/2} \atop {m+w=360}} \right. \ => \ \left \{ {{7w=2m} \atop {m+w=360}} \right. \ => \ \left \{ {{m=280} \atop {w=80}} \right.[/tex]

Answer:
Hope It Help
Brainliest please
Answer:
3
Step-by-step explanation:
The unit rate is a rate with 1 in the denominator. The unit rate for this equation would be how much money he makes in one hour. So, to find the unit rate plugin 1 for r and solve for g. One times three (1*3) is equal to 3; therefore, that is the unit rate.

Question 3 (10 points) (08.03/08.05 MC) A pair of equations is shown below:
y = 7x - 8
y = 5x – 2
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)
Answer:
part A) rearrange the equations to form simultaneous equations:
y-7x=8
y-5x=-2
now eliminate the y values by minusing the two equations:
(y-7x=8)-(y-5x=-2)
to get:
-2x=-6
x=3
now substitute x into one of the equations to get y:
y=5x-2
y=15-2
y=13
[tex]x = 3 \\ y = 13[/tex]
part B) the lines will intercept at (3, 13)

[tex]\boxed {\boxed {\sf 22a-14b}}[/tex]
Step-by-step explanation:
We are given this expression:
[tex]17a-10b+5a-4b[/tex]
We are asked to simplify. For this expression, we will need to combine like terms. Like terms are terms with the same variable. In this expression, there are 2 variables: a and b. Use the commutative property of addition to move the like terms together.
[tex](17a+5a)+(-10b+ -4b)[/tex]
Add inside the parentheses.
[tex]22a+ (-10b+-4b)[/tex]
A positive next to a negative, like +- becomes a negative.
[tex]22a+ (-10b-4b)[/tex]
[tex]22a+ -14b \\22a-14b[/tex]
The expression 17a-10b+5a-4b is equal to 22a-14b.

Answer:
132 units squared
Step-by-step explanation:
To start we can find the area of the rectangle, to do that we need to do
12*6=72
then we can find the area of the triangle, the formula to find a triangle's area of (b*h)/2, so we can do that
(10*12)/2=60
then we can add them together
72+60=132
Answer: 90
Step-by-step explanation:
Triangle=60
square=36
Now add them!
60+36=96

An inspector inspects large truckloads of potatoes to determine the proportion with blemishes prior to using the potatoes to make potato chips. She intends to compute a 95% confidence interval for this proportion. To do so, she selects a simple random sample of 90 potatoes, and finds 12 with blemishes. The 95% confidence interval is (0.063, 0.204). What is the correct interpretation for this confidence interval?
The inspector can be 95% confident that the proportion of potatoes with blemishes is 0.133.
In 95% of samples taken, between 6.3% and 20.4% of the sampled potatoes would have blemishes.
The inspector can be 95% confident that the interval from 0.063 to 0.204 captures the proportion of all potatoes on the truck with blemishes.
There is a 5% probability that the proportion of all potatoes that have blemishes is either below 0.063 or above 0.204.
Answer:
The inspector can be 95% confident that the interval from 0.063 to 0.204 captures the proportion of all potatoes on the truck with blemishes.
