Answer:

Step-by-step explanation:

1 ,3 ,0, 6 ,x

To find the mean, we add them all up and divide by the number of numbers

(1+3+0+6+x) / 5 = 3

Multiply each side by 5

(1+3+0+6+x) / 5 *5= 3*5

(1+3+0+6+x) = 15

Combine like terms

10+x = 15

Subtract 10 from each side

10+x-10=15-10

x = 5

Answer:

step 1: x+50+4x=90

the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.

step 2: x+50+4x=90

x+4x=50

5x=50

x=10

then you solve the equation, x is 10

The volume of a rectangular box is 1600 cubic inches. The height of the box is 8 inches and the length of the box is 2 times lon

Anastasy [175]

Answer:

0.833 feets

Step-by-step explanation:

Given that:

Volume of box = 1600

Heigh of box (H) = 8 inches

Let:

Width of box (W) = x

Length of box (L) = 2x

Volume of box = (Height * width * length)

1600 = (8 * x * 2x)

1600 = 16x²

x² = 1600/16

x² = 100

x = sqrt(100)

x = 10 inches

Hence, width of box in feet:

1 inch = 0.0833 feets

10 inches = (10 * 0.0833) feets

= 0.833 feets
