The caret (^) is the symbol conventionally used to indicate an exponent.

You have
  area = 2.76·10^12
  width = 4.6·10^5

You want to find the perimeter of the rectangle with these dimensions.

The perimeter of a rectangle is twice the sum of length and width.
  perimeter = 2*(length + width)
The length can be figured from the area using the formula for area.
  area = length*width
  area/width = length . . . . . . . . . divide by width
Filling in the numbers, we have
  perimeter = 2*((2.76·10^12)/(4.6·10^5) +(4.6·10^5))
  perimeter = 2*(6.0·10^6 +0.46·10^6)
  perimeter = 2*6.46·10^6 = 1.292·10^7

The perimeter of the rectangle is ...
  1.292·10^7

Find the range of the given data set. 5/8, 3/4, 1 1/8, 1 1/4 A)5/8 B)3/4 C)1 1/8
rodikova [14]

Answer:

A)5/8

Step-by-step explanation:

  • <em>The range of a set of data is the difference between the highest and lowest values in the set. </em>

<u>Given data set:</u>

  • 5/8, 3/4, 1 1/8, 1 1/4

<u>Rewriting the data set in the same denominator to compare:</u>

  • 5/8, 6/8, 9/8, 10/8

<u>As we see the smallest value is 5/8 and the highest value is 10/8, so the difference:</u>

  • 10/8 - 5/8 = 5/8

So, the range of the given data set is 5/8

<u>Correct choice is</u>: A)5/8

RSB [31]

Answer:

390 calories

Step-by-step explanation:

Divide 260 and 50, to find how much calories are in 1 gram.

260/50=5.2

1 gram=5.2 calories.

Now multiply 75 with 5.2 to find how many calories are in 75 g.

75 x 5.2=390

<u>Final answer</u>

390 calories
