It wants you to multiply the positive integers that come before it.

5! = 5 * 4 * 3 * 2 * 1
4! = 4 * 3 * 2 * 1

5!4! = 5 * 4 * 3 * 2 * 1 * 4 * 3 * 2 * 1 = 2880

latrell wants to keep his test average in his class at 85 or higher. so far, he has earned score of 85, 76, 94 and 81 on his tes

Lena [83]

Answer:

Step-by-step explanation:

Use the mean formula, mean = sum of elements / number of elements.

He wants to keep his average at 85 or higher, so plug in 85 as the mean. Let x represent the score he has to get, and solve for x:

mean = sum of elements / number of elements.

85 = (85 + 76 + 94 + 81 + x) / 5

85 = (336 + x) / 5

425 = 336 + x

89 = x

So, he has to get a 89.

Work: 4 horizontal edges on top, 4 horizontal edges on bottom, 4 vertical edges for sides

10. Ten-thousands place

Work: The 8 is highlighted. The order of places is: ten-thousands, thousands, hundreds, tens, ones

11. 10 4/5

Work: 54 ÷ 5 ——> 50÷5 = 10 with 4 left over and put into a fraction of 4/5

12. 3,000

Work: 2 is in the thousands place so you look to the place behind it and there is an 8. If the number behind is 5 through 9 then you round up. 8 is above 5, therefore, you round the 2 up to a 3.

13. 0.45

Work: The pattern is +0.03 so 0.42+0.03=0.45

Mrs. Nevin is making a costume for a school play. She needs a piece of fabric that is greater than 1/2 of a yard but less than 5

Bumek [7]

Answer:

4/7 yards

Step-by-step explanation:

Given that :

Required fabric is > 1/2 but < 5/8

Let required fabric = x

Then ;

Converting the fractions to decimal :

1/2 = 0.5 ; 5/8 = 0.625

0.5 < x < 0.625

3/8 yards = 0.375 ;

4/7 yards = 0.571

3/7 yards = 0.429

2/4 yards = 0.5

0.5 < 0.571 < 0.625

From the options, only 4/7 yards satisfies the condition :
