Answer:
boys 5:2 girls
add the ratio parts together
5 + 2 = 7
divide the total number of students by the total number of parts
35/7 = 5
now multiply each part of the ratio by 5
boys 25
girls 10
there are 25 boys
Answer:
radius ≈ 17.0 units
Step-by-step explanation:
The radius is the distance from the centre of the circle to a point on it.
Calculate the radius r using the distance formula
r = 
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (7, 12)
r = 
= 
= 
= 
≈ 17.0 ( to the nearest tenth )
The answer is a. y=3/4x + 4
To solve this equation isolate the variable and add 2/3 to both sides
Simplify 3.8x + 5.2x - 6.7 to 9x - 6.7
9x - 6.7 = 11.3
Add 6.7 to both sides
9x = 11.3 + 6.7
Simplify 11.3 + 6.7 to 18
9x = 18
Divide both sides by 9
x = 18/9
Simplify 18/9 to 2
<u>x = 2</u>
