Answer:
360
Step-by-step explanation:
The formula is (n-2)180 -> 6(180) = 1080
1080/8=135
135 is the measure of one interior angle so the exterior has to equal 45 for one side.
45 x 8=360
The answer is 360

Sam has 24 quarters, 18 nickels, and 36 dimes. He wants to divide the coins into groups so that each group is worth the same amount of money. What is the greatest number of groups Sam can make using all the coins?
HURRY PLEASE
Convert this monies to dollar
Quarters - 24 x 0.25 = $6
Nickels = 18 x 0.05 = $0.9
Dimes = 36 x 0.1 = $3.6
sum of these amounts = $10.50
the greatest group is 5 and each group would be worth $2.10

A) 3 hours
B) 40 hours
C) 20 hours
D) 10 hours
Answers
Answer:
A) 3 hours
Step-by-step explanation:
x = per hour
y = total
Dana:
y = 10x + 10
Tommy:
y = 9x + 13
Combined (Solve for x):
y = 10x + 10
y = 9x + 13 (Multiply by -1)
y = 10x + 10
-y = -9x - 13
0 = x - 3
x = 3

An initial population of 415
ducks increases at an annual
rate of 32%. Write an
exponential function to model
the duck population.
Answers
Answer:
The exponential function to model the duck population is:
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Step-by-step explanation:
In order to calculate the duck population you can use the formula to calculate future value:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:
f(n)=415*(1+0.32)^n
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years

Uh whats the area of the figure??????
Answers
Answer:
42.5
Step-by-step explanation:
The figure shown is a trapezoid
The area of a trapezoid can be calculated using this formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
The trapezoid has the following dimensions
base 1 = 7 m
base 2 = 10 m
height = 5 m
Given this information we plug in the values into the formula
[tex]A =\frac{7+10}{2} 5\\7+10=17\\\frac{17}{2} =8.5\\8.5*5=42.5 \\A=42.5[/tex]
So we can conclude that the area of the trapezoid is 42.5 square units

(y-8)+(y)+(54)=180
now solve the equation
