Answers

a) they are lighter

b)lighter by 0.0042 pounds

Answer:

A. The label is heavier than the actual weight.

B. The actual weight is 0.0042 less than the labeled weight.

Step-by-step explanation:

I hope I'm correct but here's my explanation.

A. The label said it is 0.384 and the actual weight is 0.3798, which in terms of suggesting the label is just 0.3840 and the actual weight is 0.3798, then the labeled weight would be heavier since it has either rounded up or was guessed.

B. The actual weight is 0.3798 and the labeled weight (assuming after the last decimal number it is zero) would be 0.384. Subtract, and it would be 0.0042.

Though I'm not sure if I'm 100% correct, I do think this might be the most accurate way to solve this.

Hope this helped!

Answer:

A

Step-by-step explanation:

First we need to find the perimiter of a parallelogram

Side A is the slanted line,

Side B is the 2 horizontal lines.

The equation for this is 2(a+b)

Let's plug in the measurements:

2(18+27) =

2(45) =

90

So the parallelogram is 90 now we have the perimeter of the semi cirlce already which is 18

90 + 18 = 108

Use the information to answer the following question.

The bottom of a swimming pool is 10 feet below the surface of the water in the pool. The surface of the water is represented by the number 0, and the bottom of the pool is represented by the number -10. The pool’s diving board is the same distance above the surface of the water as the bottom of the pool is below the surface of the water.

What number represents the location of the diving board?

A.
20

B.
0

C.
10

D.
1/10

Answers

Answer:

C

Step-by-step explanation:

Since the difference between 0 and -10 is 10, this means that the difference between the diving board and the pool also has to be 10. Therefore, the diving board is 10 feet above the water since 0+10 is 10.

C. since it’s above the surface of the pool which is 0 it’s at a positive elevation of 10

138 is best estimate. The half circle is smaller than half a square so it cant be more than 150.
138 is the best possible answer
