Answer:
89·98 mph
Step-by-step explanation:
First, we get the circumference of the tires:
Circumference = 
× (radius × 2)
Circumference = 3.142 × (1·5 × 2)
Circumference = 3·142 × 3
Circumference = 9·426 ft
The circumference of the tire is equal to one round.
1 round = 9·426 ft
840 rounds = ?
We cross multiply to get the length that the tires would cover in a minute
= <u>840 × 9·426</u>
1
1 minute = 7917·84 ft
60 minutes = ?
<u>60 × 7917·84</u>
1
= 475070·4 ft
5280 feet = 1 mile
475070·4 feet = ?
<u>475070·4 × 1</u>
5280
475070·4 ÷ 5280 = speed of the car in mph
89·97545
Round this off to 2 decimal places...
= 89·98 mph
hope this helps! =)
Answer:
16
Step-by-step explanation:
Basic Algebra, isolate V.
Do the opposite equation to get V on its own.
Because it is V/8, multiply both sides by 8 to get 8 on its own (if you wanted to move v over you would divide)

Answer:
<u>3x^7</u>
y^z
Step-by-step explanation:
Any <u>non-zero</u> expression raised to the <u>power</u> of 0 equals 1.
<u>3x^3y^-1z^-1</u> --> <u>3x^3y^-1z^-1</u> --> <u>3</u><u>x^7</u><u>y^-1z^-1</u>
x^-4×1z^0 x^-4×1×1 1×1
Any expression multiplied by 1 remains the same.
<u>3x^7y^-1z^-1</u>
1
Any expression multiplied by 1 remains the same.
3x^7y^-1z^-1
Any expression raised to the <u>power</u> of -1 equals its <u>reciprocal</u>
3x^7× 1/y × 1/z
Calculate the <u>product</u>
<u>3x^7</u>
