Step-by-step explanation:
We require 2 equations with the recurring part after the decimal point.
Let x = 0.555..... → (1)
Multiply both sides by 10, then
10x = 5.555..... → (2)
Subtract (1) from (2) thus eliminating the recurring decimal
(10x - x) = (5.5555 - 0.5555 ), that is
9x = 5 ( divide both sides by 9 )
x =
Answer:
B.
Step-by-step explanation:
Surface area = πr(r + L) where r = radius of the base and L = the slant height.
= 12π(12 + 40)
= 12*52π
= 624π.
Answer:
Therefore a car travelled 288 miles in 4 hours.
Step-by-step explanation:
Given:
The car travels at the rate of 72 mph
Equation is given by
To Find:
How far a car travels in 4 hours = ?
Solution:
Distance covered is equal to the product of speed and time.
We have
.............Given
where,
d = distance
t= time
So at t = 4 hours
Therefore a car travelled 288 miles in 4 hours.
It is already rounded to the nearest hundreth. .5 is a tenth, .06 is a hundreth.
2/3 x 5/3 = 10/9
= 1 1/9 (1 and 1/9)
answer 1 1/9 cans is needed
