The x axis and the y axis
Answer:
cos(O) = 39 / 89
Step-by-step explanation:
Given:
ΔOPQ, where
∠Q=90°
PO = 89
OQ = 39
QP = 80
cosine of ∠O?
cos(O) = Adjacent / Hypotenuse
cos(O) = 39 / 89
Answer:
For company A, y = 24x + 42
For company B, y = 28x + 25
Step-by-step explanation:
x is the number of containers
y is the total cost
For company A, y = 24x + 42
For company B, y = 28x + 25
For the cost of both companies to be the same, then
24x + 42 = 28x + 25
28x - 24x = 42 - 25
4x = 17
x = 4.25
Mr Lycan would have to order about 4 containers so the cost would be the same from each company

No solution
Step-by-step explanation:
n+7=n+3
First subtract n to the other side:
n-n+7=n-n+3
7=3
No solution
Answer:
The number is 70
Step-by-step explanation:
Is means equals and of means multiply
91 = 130% *W
Changing to a decimal form
91 = 1.3W
Divide each side by 1.3
91/1.3 = 1.3 W/1.3
70 = W
