Answer:
2 : 3
Step-by-step explanation:
Given ratio of sides of 2 similar triangles = a : b , then
ratio of areas = a² : b²
Here by working in reverse
ratio of areas = 4 : 9 , thus
ratio of sides = : = 2 : 3

Step-by-step explanation:
Distance Formula D RT
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour
Answer:
Inequality: 8.25x + 54 = 9.75
Step-by-step explanation:
Why?
It will take 36 hours for David to have as much as Fatima.
David :
Initial saving = 54
Pay per hour = $8.25
While Fatima :
Pay per hour = $9.75
Let number of hours worked = x
David's total = $8.25x + 54
Fatima's total = 9.75x
In other to have the same amount :
8.25x + 54 = 9.75x
The like terms :
8.25x - 9.75x = - 54
-1.5x = - 54
x = - 54 / - 1.5
x = 36
Therefore, it’ll take 36 hours for David to have as much as Fatima.
Answer:
178 sq in
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, we know the formula for finding the area of a rectangle is B*H, and the formula for finding the area of a circle is πr^2
Let's find the area of a rectangle first:
25*6=150 sq in
Now the semicircles {which combined into one whole circle because they're two halves}:
The diameter is 6 inches, so the radius is 3 inches.
π(3)^2=9π
9*π=28.27 which can be rounded down to 28 sq in.
To fin the area of both, we would add them together:
150+28=178 square inches
