Answers

The least common denominator (LCD) of the fractions 1/3 and 3/4, which is a common multiple of their denominators is: 12.

Recall:

  • LCD stands for "least common denominator" or "lowest common denominator".
  • LCD is the smallest multiple that is common among the denominators of a set of fractions.

Given two fractions, 1/3 and 3/4:

Their denominators are 3 and 4.

The common multiple between 3 and 4 is 12.

How do you simplify 15/32?

Answers

Factor each nmber down to prime factors. If they have any factors in common, they can be simplified. 

15 is 5 times 3 

32 is 2 times 2 times 2 times 2 times 2 

No factors in common.

That is as simplified as it will get.

Sorry!
It is actually impossible, because 15 and 32 have no common factors.

The perimeter of a rectangle is 96 ft. The ratio of the length to the width is 7:5. what are the dimensions of therectangle?

Answers

Perimeter = 2(l + w) = 2(7x + 5x) = 2(12x) = 24x = 96
x = 96/24 = 4.
Therefore, length = 7 x 4 = 28 ft and width = 5 x 4 = 20ft

The weights, in pounds, of the upper-class men offensive line players for a college are shown below: 322, 290, 321, 326, 330, 315, 311, 292, 290 What is the average, or mean, weight of the upper-class men offensive players? Provide your answer with 3 sig figs. -311 pounds -315 pounds -290 pounds -318 pounds

Answers

Answer: 311 pounds

Step-by-step explanation:

To find the average, add up all of the values and divide by the amount of values.

First add up all of the values.

322+290+321+326+330+315+311+292+290 = 2797

Now count how many values there are and divide your previous sum by it.

2797/9 = 310.78

Because you need to have 3 sig figs, round to the nearest one.

310.78 rounds up to 311.

answer-311

Step-by-step explanation:

322+290+321+326+330+315+311+292+290=2797

Count the number of values and divide by 2797

2797 divided by 9 =310.77777777777777

Nearest one-311
