Solve the equation.<br> 0.95x +0.05(12-x) = 0.10(24)

Nostrana [21]

Answer:

x=2

Step-by-step explanation:

0.95x +0.05(12-x) = 0.10(24)

Distribute

0.95x +0.6-0.5x= 2.4

add/subtract like terms

0.9x+0.6=2.4

subtract 0.6 from both sides

0.9x=1.8

Divide both sides by 9

0.1x=0.2

multiply both sides by 10

x=2

A window in Michael's room is the shape of a trapezoid. The bases are 30 inches and 40 inches. The height of the window is 24 in

lana [24]

Answer:

The area of the window is of 840 square inches.

Step-by-step explanation:

To find the area of an trapezoid, we need to add the sum of the bases, multiply by the height, and then divide by 2.

Matematically:

$A = \frac{(b_{1} + b_{2})*h}{2}$

In which $b_{1}$ and $b_{2}$ are the bases and h is the height.

In this question:

$b_{1} = 30, b_{2} = 40, h = 24$

All the measures in inches, so the area is in square inches.

$A = \frac{(30 + 40)*24}{2} = 840$

The area of the window is of 840 square inches.
