Answer:
D. Square
Step-by-step explanation:
Neither a Cube or a Square pyramid have an ellipse, hexagon or octagon on them anywhere, and a cube doesn't have a triangle on it, so the only thing out of these choices that these even have in common is a square.
I hope this explains it!
-25x + 40
Step-by-step explanation:
-8 (4x-5) + 7x
-32x + 40 + 7x
-32x +7x + 40
-25x + 40
if there's 3 counselors / 45 students.
3 counselors / 45 students = 1 counselor / 15 student
10 counselors multiplied by 15 students = 150 maximum students allowed.
Tanya paints 55 ft^2 / 30mins.
60 mins = 1 hour
60 mins / 30 mins = 2
55 multiplied by 2 = 110
(There were two different people mentioned in the problem)
Tanya, or Angela, paints 110 square feet every hour.
Answer:
y = -1/3x + 5
Step-by-step explanation:
Find slope.
m = y₂ - y₁ / x₂ - x₁
Two points given.
(0,5) (3,4)
m = 4 - 5 / 3 - 0
m = -1 / 3
y = -1/3x + b
Substitute x and y by an point. Let's take (0,5)
0 - x
5 - y
5 = -1/3(0) + b
5 = 0 + b
5 - 0 = b
5 = b
So,
y = -1/3x + 5
