Answer:
The missing exponent is 4
Step-by-step explanation:
Let
Then we rewrite the LHS in scientific notation to get;
This implies that,
By comparison, we find n=4.
Therefore the missing exponent is 4
Answer:
6 hours
Step-by-step explanation:
The equation for this would be
c=3h+12
It costs $3 per hour, and there is a $12 cost no matter how many hours the bike is rented for
We know,c, or the cost is $30, so we can substitute that in
30=3h+12
Solve, by isolating the variable,h
First, subtract 12 on both sides
30=3h+12
18=3h
Divide by 3 on both sides
h=6
So, she rented the bike for 6 hours

Delta Math
Step-by-step explanation:
Volume of a cylinder is:
V = πr²h
V = (3.14) (4 in)² (5 in)
V = 251.2 in³
Volume of a cone is:
V = ⅓ πr²h
V = ⅓ (3.14) (4 in)² (15 in)
V = 251.2 in³
The volumes are equal.
