61 boxes :)

A= lw

We know the area and one of the variables-

518.50= 8.5w

Divide 518.5 by 8.5

518.5/8.5= 61

61 boxes!

SSSSS [86.1K]

Answer:

2.15%

Step-by-step explanation:

If you were to get the z-score for both 500 and 550 and then get the probability of both those z-scores. After getting the probability you would subtract both probability and get your answer.

Z-score:

550-400/2=3

500-400/2=2

Probability:

3 (from the Z-table) is .9987

2 (from the Z-table) is .9772

.9987-.9772= .0215

.0215 as a percentage is 2.15%

Vera_Pavlovna [14]

Answer:

see the explanation

Step-by-step explanation:

Let

x ---> kilograms of cement needed

y ----> kilograms of sand needed

z ----> kilograms of gravel needed

we know that

x:y:z=1:3:4 ----> x+y+z=1+3+4=8

x+y+z=480\ kg

Divide 480 by 8

480/8=60 ----> scale factor

Multiply the scale factor by the ratio 1:3:4

<em>Find out the kilograms of cement needed</em>

60(1)=60\ kg

<em>Find out the kilograms of sand needed</em>

60(3)=180\ kg

<em>Find out the kilograms of gravel needed</em>

60(4)=240\ kg
