Answer:
ABC= 60 XYZ=540
Step-by-step explanation:
The area of a triangle is 1/2*base*height so for ABC we need to find the height first. To do this we use pythag theorem, and create the equation 13^2=5^2+height^2 rearranging this we can figure out that sqrt(height)=13^2-5^2. For the base we do 2*5 since there are two congruent line segments both equal to 5. Using this we can do 1/2*12*10=area of ABC
For XYZ we can do 1/2*30*36=area of XYZ, we can do 2*15 since there are 2 congruent 15 length line segments at the base.

Fourteen percent of the town's population is over the age of 65. If there are 320
residents over the age of 65, approximately what is the town's population?
Answers
Answer:
2,285.7143
Step-by-step explanation:
There are two ways of doing this.
#1: Take 320, and divide it by the 14%. This should get you how many people are eqivlelent to 1 percent. When I did it out, 320/14 is equal 22.857143...
Remember this is 1%, and we need to find 100%. So we need to multiply the 1%, which was 22.857143, by 100.
This should get you 2,285.7143.
#2 Take your 100%, and divide it by the 14% that make up the 65+ population. This should get you 7.1428571.
Now you just have to multiply this number by the amount of 65+ residents, which is 320. So you should multiply 320x7.1428571.
This should get you the same exact answer, 2,285.7143

Answers
Answer:
Average time for West Middle was maximum.
Step-by-step explanation:
Average time for a track meet for schools = [tex]\frac{\text{Time}}{\text{Distance}}[/tex]
For Eastbay Middle,
Average time per mile = [tex]\frac{42}{7}[/tex]
= 6 minutes per mile
For Northwest Middle,
Average time = [tex]\frac{25}{5}[/tex]
= 5 minutes per mile
For South Central Middle,
Average time = [tex]\frac{28}{4}[/tex]
= 7 minutes per mile
For West Middle,
Average time = [tex]\frac{48}{6}[/tex]
= 8 minutes per mile
Therefore, average time for West Middle (8 minutes per minute) was maximum.

Area of triangle = 8.9
Area of parallelogram = 53.4 yd² (option A)
Step-by-step explanation:
✔️Area of the triangle = ½*base*height
base = 3 m
height = 5.9 m
Area of triangle = ½*3*5.9
Area of triangle = 8.85 ≈ 8.9 (nearest tenth)
✔️Area of parallelogram = base*height
base = 8.9 yd
height = 6 yd

Circumference = diameter x pi
= 6 x 3.14 = 18.84
We have the circle split into 2 halves, but the circumference remains the same

Answers
The question is incomplete:
James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20 what is the total amount james has in quarters?
a. $10.00
b. $6.20
c.$15.50
d.$25.00
Answer:
d.$25.00
Step-by-step explanation:
With the information provided, you can write the following equations given that dimes are equal to 0.10 and quarters to 0.25 to determine the number of dimes and quarters that James has:
x+y=162 (1)
0.10x+0.25y=31.20 (2), where:
x is the number of dimes
y is the number of quarters
First, you can solve for x in (1):
x=162-y (3)
Then, you have to replace (3) in (2) and solve for y:
0.10(162-y)+0.25y=31.20
16.2-0.10y+0.25y=31.20
0.15y=31.20-16.2
0.15y=15
y=15/0.15
y=100
Finally, you have to replace the value of y in (3) to find x:
x=162-100
x=62
Now, you know that James has 100 quarters and you can multiply this number for the value of a quarter to find the amount James has in quarters:
100*0.25=25
According to this, the answer is that James has $25 in quarters.
