Answer:
The power developed by the 1st crane is twice the power developed by the 2nd crane.
Step-by-step explanation:
According to the question,
work done by both of the cranes are the same. Let it be W.
Then power developed by the first crane,
= unit -----------------(1)
and, the power developed by the 2nd crane,
= unit ------------------(2)
So, we get that,
So, the power developed by the 1st crane is twice the power developed by the 2nd crane.
Answer:
$5.20
Step-by-step explanation:
Find the tax rate first:
$1.20
-------------- = 0.04
$30.00
The tax rate is 4%.
Then the tax on a $130 item is 0.04($130) = $5.20
Answer:
∠ZB = 54°
Step-by-step explanation:
Given:
Pair of complementary angles
∠ZA = (2x + 10)° and m
∠ZB = (3x + 15)
Find:
Measure of ∠ZB
Computation:
complementary angles
a + b = 90°
∠ZA + ∠ZB = 90°
(2x + 10) + (3x + 15) = 90
5x + 25 = 90
x = 13
So,
∠ZB = (3x + 15)
∠ZB = 13(3) + 15
∠ZB = 54°
