Answer:
w = 15 cm
Step-by-step explanation:
We want to find the width, as the area of a rectangle is length (l) * width (w).
Since we know the area and the length, we have 480 = 32w
Isolating w by dividing both sides by 32 gives us w = 15 cm
The capacity in liters will be 0.7L
Answer:
The answer is 0.2mile
Step-by-step explanation:
The vertical height of the building, which is 630ft, is opposite the angle of elevation (30°).
While the horizontal distance to the tower is adjacent to the building. So, we take the tangent of the angle of elevation in terms of this unknown distance (x) and the vertical height.
So,
Tangent = opposite ÷ adjacent
Tan30° = 630ft ÷ x
x = 630ft ÷ tan30°
x = 1091.192ft
But,
1 mile = 5,280ft
1091.192ft = (1/5280) x 1091.192
= 0.2mile
Answer:
b. -x^2 + 50 = 25
c. |2x| = 10
d. x < 0
e. 2x < 10
Step-by-step explanation:
x = -5
-(-5)² + 50
-25 + 50 = 25
|2(-5)| = |-10| = 10
-5 < 0
2(-5) = -10 < 10
