Answer:
2.43 (units)
Step-by-step explanation:
Circumference of a circle is defined by C=2pi*r
Solving that equation for r --> 5.5 = 2* 3.14 * r
r=0.88 unit
Area of a circle = A= pi * r^2
Solve this equation by plugging in the r we just found. A = 3.14 * (0.88^2)
Answer: 2.43 units
Answer:
(A) 46 seconds
Step-by-step explanation:
You can arrive at an answer to this question at least two ways:
<h3>1)</h3>
Read the time from the graph.
Locate 144 on the vertical scale, just below halfway from 140 to 150. Locate the point on the graph that is at this vertical height. It is a little more than halfway between 40 and 50 on the horizontal scale.
The only answer choice in that neighborhood is t = 46 seconds.

<h3>2)</h3>
Use the given formula, and solve it for the time.
d = 1.5t +75
144 = 1.5t +75 . . . the distance of interest is 144
69 = 1.5t . . . . . . . .subtract 75
69/1.5 = t = 46 . . . seconds
Answer:
Pete worked for 4 hours.
Step-by-step explanation:
If you subtract his tips from his overall total (50-16) you get 34. Now you divide what's left of his total by his hourly wage (34/8.5) which gets you 4.
Answer:
W' = 54.4 pounds
Step-by-step explanation:
Given that,
The weight of a bag of books = 40 pounds
After picking up some books at school, the weight has increased by 36%.
We need to find the weight of the bag now. Let the new weight is W'.
So,
W' = 40 +36% of 40
i.e.
So, the new weight of the bag is equal to 54.4 pounds.
