72, because 360/4 courses = 90 as an average for Adrianna. This means that 360/5 courses equals 72 for roberto.
To find 75% of 200, we can multiply two fractions.
75/100 * 200/1
Now, just multiply the numerators and the denominators separately.
75 * 200 = 15000
100 * 1 = 100
Now, divide.
15000/100 = 150
<h3>75% of 200 is 150.</h3>
Well your answer for problem 4 is 28. IM not sure what the boxes are for though...
45/X + 63/X= 108/X = Y, X= 108 divided by 2 = y, y=54
Answer:
Area of composite figure = 216 cm²
Hence, option A is correct.
Step-by-step explanation:
The composite figure consists of two figures.
1) Rectangle
2) Right-angled Triangle
We need to determine the area of the composite figure, so we need to find the area of an individual figure.
Determining the area of the rectangle:
Given
Length l = 14 cm
Width w = 12 cm
Using the formula to determine the area of the rectangle:
A = wl
substituting l = 14 and w = 12
A = (12)(14)
A = 168 cm²
Determining the area of the right-triangle:
Given
Base b = 8 cm
Height h = 12 cm
Using the formula to determine the area of the right-triangle:
A = 1/2 × b × h
A = 1/2 × 8 × 12
A = 4 × 12
A = 48 cm²
Thus, the area of the figure is:
Area of composite figure = Rectangle Area + Right-triangle Area
= 168 cm² + 48 cm²
= 216 cm²
Therefore,
Area of composite figure = 216 cm²
Hence, option A is correct.
