At the grocery store watermelon costs $1.27 per pound. If Heather buys a 5.5 lb watermelon, which proportion could she use to find out how much it will cost, c?

Answers

If you would like to know how much will the watermelon cost, you can calculate this using the following steps:

$1.27 ... 1 pound
$c = ? ... 5.5 pounds

1.27 * 5.5 = 1 * c
c = 1.27 * 5.5
c = $6.99

The correct result would be: c = $1.27 * 5.5 pounds = $6.99.

Answer:

It's D.) 1/1.27 = 5.5/c

Step-by-step explanation:

Set up the proportion to be  

weight in pounds

cost

. Keeping the variables the same on both sides the correct proportion is

1 /1.27

=  

5.5 /c .

An angle measuring (870n)° is in standard position. For which value of n will the terminal side fall along the positive portion of the y-axis?

Answers

An angle measuring (870n)° is in standard position.The value of n in which the terminal side falls along the positive portion of the y-axis would be 1. This is because the reference angle would fall on the second quadrant, which still denotes a positive portion of the y-axis.

Which measurement is most accurate to describe the weight of a quarter?630 g
63 mg
6.3 g
0.63 kg

Answers

Answer: 6.3 g

Step-by-step explanation:

First, we need to put every mesure into the same unit. Let's put all into grams.

- kg would be too heavy for a quarter (consider that we use kg to weight people, for example)

- mg is too light (consider that we use mg to weight pills, for example)

We know that

1 kg = 1000 g

1 g = 1000 mg

630 g = 630 g

63 mg  = 63/1000 = 0.063 g

6.3 g  = 6.3 g

0.63 kg = 0.63*1000 = 630 g

The most suitable answer for a quarter is 6.3g, because 630 g would be too heavy and 0.063 g would be too light.
63 mg it is the smallest measurement listed.
