The number of unit squares with a side length of 1/10 foot that Rhys uses to tile the rectangle is 24 units
<h3>How to calculate the area of plane shapes?</h3>
A square is a plane shape with 4 sides
The formula for calculating the area of the square is expressed as:
A = l^2
Given
side length of a square = 1/10 foot
A = (1/10)² = 1/100 = 0.01 square foot
<u>Determine the area of the rectangle</u>
Area = length * width
Area = 3/10 * 4/5
Area = 12/50 = 6/25
Area = 0.24 square foot
<u>Take the ratio of both areas</u>
Ratio = 0.24/0.01
Ratio = 24 units
Hence the number of unit squares with a side length of 1/10 foot that Rhys uses to tile the rectangle is 24 units

Answer:
54. slope: -1/5 y-intercept: -6
55. slope: -3x y-intercept: 12
Step-by-step explanation:
Answer:
Step-by-step explanation:
What is known....AC=75 AB=4 times BC AB+BC=AC
4(BC)+BC=75 Add like numbers
4(BC)+BC=5BC
5(BC)=75 get the variable(BC) alone by dividing both sides by the number(5)
5(BC)/5=75/5 Then simplify....5(BC)/5=(BC) and 75/7=15
(BC)=15
