THE 5 IDENTICAL SHELVES WOULD have to be 76 because if you take 400 - 20 (because that left over) you get 380/5 you get 76 and to check your work you do 5x76=380+20 you get 400 so 76 is you answer
Answer:
(0,-2)
(1,-1)
(5,-3)
Step-by-step explanation:
To solve this question, all you need to do is put the x coordinate in for x and the y coordinate for y. (x,y) We need to find the equation that is less than or equal to 3.
Answer:
x = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° =
, then
sin45° =
=
=
( cross- multiply )
x ×
= 9
( divide both sides by
)
x = 9
Answer:

Step-by-step explanation:
The formula of an area of a parallelogram:

b - base
h - height
We have:
base₁ = 9.8 in
base₂ = 10 in
height₁ = 5.6 in
height₂ = h
The area of a parallelogram:
and 
Therefore we have the equation:

Substitute:

<em>divide both sides by 10</em>
