In the pully system shown in this figure, MQ = 10 in, NP = 3in and QP=24in. Find MN
1 answer:
Answer:
The correct option is a. The length of MN is 25.
Step-by-step explanation:
Given information: MQ = 10 in, NP = 3 in and QP=24 in.
If the centers of two circles of radius r₁ and r₂ are d units apart, then the length of the direct common tangent between them is
Square both sides.
Take square root both sides.
Therefore length of MN is 25 and option a is correct.

Hello! First, let's get some important information:
Luke works in the:
- week → grocery store → $16/hour
- weekend → nursery → $22/hour
Now, let's analyze the questions:
<h3>a) How much does he earn if he works 5 hours at the grocery store and 8 hours at the nursery? </h3>To find the amount he will receive, you must multiply the amount of 1 hour by the number of hours worked. Look:
<h3>c) Total pay, 5 hours at the grocery store and 8 hours at the nursery:</h3>
You'll just have to just add the value in each of the jobs:
$80 + $176 = $256
<h3>d) Total pay, g hours at the grocery store and n hours at the nursery:</h3>Adding the values of each job:
$16g + $22n
Hope this helps!
