Answer:
The answer is 20 feet by 20 feet. Let's solve the equation: (x – 8)^2 = 144. (x - 8)^2 = 12^2. Since a^2 = b^2 is the same as a = b, then (x - 8)^2 = 12^2 can be simplified to: x - 8 = 12. Now, solve for x. x = 8 + 12. x = 20. Therefore, the dimensions of the original lawn were 20 feet by 20 feet.
Answer: x = 5

the expanded form of 4.875 inches in fraction
Since 4.875 is a decimal number, with a whole number and a decimal number, we
need to convert it to fraction first
=> 4 = 4/1
=> .875 = 875/1 000 , because 8 is tenths, 7 has a place value of hundredths
and 5 has a place value of thousandths, that’s why it is over 1 000
Now, the expanded form of the given number is this:
=> 4/1 + 875/1 000

1) 3.25n
Overall cost of n gallons of gas
2)3.25n = 26
we are spending 26 dollars on 8 gallons of gas
3)40-3.25n
Ammount we have remaining after spending on n gallons of gas out of 40 dollars
4) 40-3.25n = 1.00
The maximum number of gallons of gas we can buy from 40 dollar is 13 gallons and 1 dollar is still remaining to us.
Answer:
$2942.27
Step-by-step explanation:
Given the circumference of a circle, we can get the radius which will then help us get the area and finally estimate the cost of tiling.
C=2πr
Where C is circumference and r is radius
Making r the subject of the formula then
r=C/2π
Substituting 157 ft for C then
r=157/2π=24.9873260654276 ft
Area, A is given by A=πr²
A=π*(24.9873260654276)²=1961.50509613606
Rounded off, the area is 1961.51 ft²
Given the cost per unit square foot as $1.5 then the overall cost will be
$1.5*1961.51=$2,942.265
Rounded off as $2942.27
