It would be 4 mph because 48 divided by 12 is 4.
Answer:
.2 degrees
Step-by-step explanation:
180-170 is 10
10/50 is .2
Answer:
Width is 20cm
Step-by-step explanation:
Step one:
Given data
let the width be x
W= x
L= x+5
P= 90
Step two:
The expression for the perimeter is
P= 2L+2W
90= 2*x+2(x+5)
90= 2x+2x+10
collect like terms
90-10=4x
80= 4x
divide both sides by 4
x= 80/4
x= 20
Answer:
A. 4·10⁴
Step-by-step explanation:
The problem statement tells you ...
6×10⁵ miles = 15 × (last year's mileage)
Dividing by 15 gives ...
(60×10⁴ miles)/15 = (last year's mileage) = 4×10⁴ miles
_____
<em>Further explanation</em>
An exponent is an indication of repeated multiplication.
10⁵ = 10·10·10·10·10 = 100,000
We can use the associative property of multiplication to rewrite the number of miles:
6×10⁵ = 6·(10·10·10·10·10) = 600,000 = (6·10)·(10·10·10·10) = 60×10⁴
Answer:
201.143 (approx.) cm²
area of circle = (pi)x(radius)^2
= 22/7 x (8)^2
=22/7 x 64
= 1408/7
= 201.142857143
= 201.143 cm^2 (approx.)
