Answer: the number of students that were surveyed is 40
Step-by-step explanation:
Let x = total number of students that were surveyed about their favorite colors
1/4 of the students preferred red.
This means that the number of students that preferred red is 1/4 × x = x/4
1/8 of the students preferred blue.
This means that the number of students that preferred blue is 1/8 × x = x/8
The remaining number of students will be the total number of students - the sum of the number of students that preferred red and the number of students that preferred blue. It becomes
x - (x/4 + x/8) = x - 3x/8 = 5x/8
3/5 of the remaining students were for green. This means that the number of students that preferred green is 3/5 × 5x/8 = 3x/8
if 15 students prefer green, then
3x/8 = 15
3x = 120
x = 120/3 = 40 students
Answer:
28.56 m²
Step-by-step explanation:
What we need to do for the quarter circle is use the following formula: 1/4(πr²)
(4 * 4) + 1/4(3.14 * 4²)
16 + 1/4(3.14 * 16)
16 + 1/4(50.24)
16 + 12.56
28.56 m²
The best approximation for the area of this figure is 28.56 m².
The answer is 0.3 cause when you subtract all of it you can get it
Answer:
17
Step-by-step explanation:
The equation 11x + 10y = 32 is a linear equation, and the solution to the linear equation 11x + 10y = 32 is 
<h3>How to solve the equation?</h3>
The equation is given as:
11x + 10y = 32
Subtract 11x from both sides
10y = 32 - 11x
Divide both sides by 10
Hence, the solution to the linear equation 11x + 10y = 32 is
