First, Make 2 equations to show each company in which "x" equals the number of days:
Andy's Rental Car = 20 + (30x)
Buddy's Rental Car = 36 + (28x)
Set it up like this:
20 + (30x) = 36 + (28x)
Now, solve for x by simplifying both sides of the equation and then isolating the variable.
x = 8
8 Days
Answer:
12 feet
Step-by-step explanation:
A driveway is rectangular in shape.
Therefore we can calculate the area using the formula;

From the question;
The area,A=96 feet square
The width, W=8 feet
We substitute this values into the formula to find the length, L.
This implies that

Dividing through by 8.


Hence,the length of the driveway is 12 feet.
Answer:
1152\pi\
Step-by-step explanation:
Answer:
No, Noah used the diameter instead of the radius in the calculations.
V = 91.13π
Step-by-step explanation:
Noah is working on a geometry problem that involves finding the volume of a sphere with a diameter of 9 units. His work is shown below.
V = πr3
V = π(9)3
V = π(729)
V = 972π cubic units
Is Noah’s work correct
Volume of a sphere, V = πr³
radius, r = diameter / 2
Diameter = 9 units
r = 9 / 2
= 4.5 units
Volume of a sphere, V = πr³
= π × 4.5³
= π × 91.125
= 91.125π
Approximately 91.13π
V = 91.13π
No, Noah used the diameter instead of the radius in the calculations.
Answer:
n = -1
Step-by-step explanation:
First distribute the -4
15-4n+8=27
Combine 8 & 15
-4n+23=27
Subtract 23 from each side
-4n=4
Divide each side by -4
n=-1
