Answer: 0.8 or 80%
Step-by-step explanation:
First find the total number of marbles:
10 + 15 + 25 = 50 marbles total
To find the number of marbles that are not black:
15 + 25 = 40 marbles that are not black
Set up ratio:
= 0.8 or 80%
60 minutes in an hour
60÷12=5
1,000 meter in 1 km
5×1=5
5×1000=5000
therefore, 5000 meters
He should add exact since money is involved
he could also estimate since they are so close together, but he would be off only 2 cents

Answer:
Question 37:
B) 21
Step-by-step explanation:
How I found the radius:
radius= 132/ 2 x π
r=132 / 6.2831853071796
r=21.0084525
Divide 132 by 6.2831853071796
π = 3.1415926535898

Answer:
y=6^x-2
Step-by-step explanation:
Start with the parent function, a^x. The graph looks like it has been translated b units down, so our function is a^x+b. Now at x=0, y=-2. So b=-2. Next at x=1, y=3. 3=a^(1)-2, a=6. y=6^x-2 is the equation
