Answer:
352 ft (squared) , he will need 12 paint cans
Step-by-step explanation:
Two 12 by 8ft walls = 192 ft in area, Two 10 by 8ft walls = 160 ft in Area, that equals 352 ft total, 352/30=11.73 repeated, round up to 12
The area of the reduced rug is 25 square feet
<h3>How to determine the area?</h3>
The dimensions are given as:
Length = 12.5 feet
Width = 10 feet
The area is calculated as:
Area = Length * Width
So, we have:
Area = 12.5 * 10
Evaluate
Area = 125
When reduced by one-fifth, we have:
Area =1/5 * 125
Evaluate
Area = 25
Hence, the area of the reduced rug is 25 square feet

Answer:
Please check the explanation.
Step-by-step explanation:
If the ratio y/x is the same for all related pairs of x and y, it means it represents a proportional relationship.
In other words, '
' varies proportionally with '
' or that '' is directly proportional to ''.
When we say the ratio is the same, it means when '' increases, '' increases and as '' decreases, '' decreases
Using the equation
y ∝ x
y = kx
k = y/x
Where 'k' is the proportionality constant.
Answer:
Step-by-step explanation:
8b - 7 = 7b - 2
Bringing like terms on one side
8b - 7b = - 2 + 7
B = 5
-12 + 5k = 15 - 4k
Bringing like terms on one side
5k + 4k = 15 + 12
9k = 27
k = 27/9 = 3
