Answer: x = 7
`Step-by-step explanation:
Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:
9 cm 72 cm
----------- = -----------
3x - 20 56 cm
Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²
Dividing both sides by 72 cm, we get:
3x - 20 = (504 cm²) / (72 cm) = 7
Then 3x - 20 = 7, and 3x = 27. Then x must be 9.
In the given question , we have a function given , which is
And we need to find the value of y when x=5.
So we substitute 5 for x and solve for y, that is
And on rounding to the nearest tenths, we will get
So when x=5, y=0.4

Step-by-step explanation:
A
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter ) , then
C = 3.14 × 8 ≈ 25.12 in
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 94.2 , then
2πr = 94.2 ( divide both sides by 2π )
r = 
= 15 cm
Answer: D) 48.75
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a rectangle: length x width
Replacing with the values given and solving for A (area)
A= 7.5 ft x 6.5 ft =48.75 ft2
The area of the garden in square feet is 48.75. (option D).
