Answer:
The speed of the tyre of the car is 1002.24 feet per minute .
Step-by-step explanation:
Given as :
The radius of the car wheel = r = 16 inches
Since 12 inches = 1 feet
So, 16 inches = 
×16 = 1.33 feet
The number of revolution of the wheel = 120 revolution per minute
Let The speed of the wheel = s feet per minute
The circumference of wheel = 2 × 
× radius
where = 3.14
or, circumference = 2 × 3.14 × 1.33
Or, Circumference = 8.352 feet
Now , Speed = circumference of wheel × number of revolution
or, Speed = 8.352 feet × 120 revolution per minute
∴ Speed = 1002.24 feet per minute
Hence The speed of the tyre of the car is 1002.24 feet per minute . Answer
Answer:
x < 9
Step-by-step explanation:
Move the -4 over as if there was an equal sign so that x < 9
Take the arrow that looks like this "<---O" that is not filled in and put it on the number 9.
Let me know if this helps <3
Answer:
the answer would be 9.

Step-by-step explanation:
Answer:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.
Step-by-step explanation:
Suppose that we have a cube with sidelength M.
if we rescale this measure with a scale factor 8, we get 8*M
Now, if previously the area of one side was of order M^2, with the rescaled measure the area will be something like (8*M)^2 = 64*M^2
This means that the ratio of the surfaces/areas will be 64.
(and will be the same for a pyramid, a rectangle, etc)
Then the correct options will be the ones related to surfaces, that are:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.
