Answer:
Step-by-step explanation:
Find the rate that was charged for Lara's time
rate = dollars / hour
The use this rate to calculate how many hours it took to clean Roy's house, since the rates are the same. Solve for hours.....
rate for Lara = dollars / hour = $150 / 3 hour = $50 / hour
rate for Roy = dollars / hour Solve for hours
multiply both sides by hours
(rate for Roy) (hour) = (dollars / hour) (hour)
(rate for Roy) (hour) = (hour) (dollars / hour) right side hours cancel
(rate for Roy) (hour) = (dollars) divide both sides by (rate for Roy)
(rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)
now the rate for Roy on the leftside cancel
(rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)
(hour) = (dollars) / (rate for Roy) Plug in $225 charged to Roy
and the $50 / hour rate
hour = $225 / ($50/hour) ( 1 over 1 / hour ) = hour
= $(225/50) hour think about 1 / (1/2) = 2 the same with units
hour = 4.5 hours
Answer:
length/width = 1/1 = 1
Step-by-step explanation:
(3x)(2x) = 12150
6x^2 = 12150
x^2 = 2025
x = 45
Length is 135 ft, width is 90 ft, perimeter is 450 ft
Geometric mean: 135 : x :: x : 90
x^2 = 12150
x = 45√6
The second rectangular piece of land is a square !
length/width = 1/1 = 1
Answer:
2/15
Step-by-step explanation:
Step 1: 4/5 x 1/2 = 2/5
Step 2: 2/5 x 1/3= 2/15
Hope this helped!
Complementary angles add to 90 degrees. This means that 65 + x = 90, so x = 90 - 65 = 25.
