Find the area. Round your answer to the nearest hundredth 15m

the area of a window is 192 in squared. The width if the window is four inches more than half the length of the window. What are

Leya [2.2K]

Answer:

Length = 16 inches and width = 12inches

Step-by-step explanation:

A = 192 in² . The width is 4 + 1/2x. therefore let x = length

Area = LW

192 = x(4 + 1/2 x)

192 = 4x + 1/2x²

384 = 8x + x² Multiply each term by 2 to make a

384 + 16 = x² + 8x + 16 Complete the square

400 = (x + 4)²

$\sqrt{400} = \sqrt{(x + 4)^2}$

± 20 = x + 4

20 = x + 4 or -20 = x + 4

20 - 4 = x or -20 - 4 = x

16 = x or -24 = x reject the negative amount

Length = 16

width = 4 + 1/2(16); 4 + 8 = 12

Please help me write an equation.

vekshin1

Answer:

k=6

Step-by-step explanation:

Line partition formula

1/b(x2-x1)+x1, 1/b(y2-y1)+y1

Where b is the number partitions.

We know the x values so Subsitue 17 for x2 and 2 for x1. and we know this value must equal 7.

1/b(17-2)+2=7

1/b(15)=5

1/b=1/3

b=3

so the partition is 1/3

$\frac{1}{3} (17 - 2) + 2 = 7$

So let find the y coordinate

$\frac{1}{3} (8 - 5) + 5 = 6$

So our y coordinate is 6.

How can you use a right angle to dicide how to name another angle?

DanielleElmas [232]

If it is a square, subtract (90+ whatever the other angle is) from 360. If it is a triangle than add 90 plus whatever other number the other angle is then subtract it from 180. A triangle is 180 degrees, and a square is 360 degrees.

Convert each of the following estimates of useful life to a straight-line depreciation rate, stated as a percentage: (a) 10 year

Rzqust [24]

Answer:

a.10 years 1 / 10 x 100 10% per year

b. 8 years 1 / 8 x 100 12.5% per year

c. 25 years 1 / 25 x 100 4% per year

d. 40 years 1 / 40 x 100 2.5% per year

e. 5 years 1 / 5 x 100 20% per year

f. 4 years 1 / 4 x 100 25% per year

g. 20 years 1 / 20 x 100 5% per year

Step-by-step explanation:

Under straight line method of depreciation, equal amount of the depreciation is reduced throughout the useful life of the asset. Using the following formula:

Straight line depreciation rate = 1 / Useful Life x 100

So:

a.10 years 1 / 10 x 100 10% per year

b. 8 years 1 / 8 x 100 12.5% per year

c. 25 years 1 / 25 x 100 4% per year

d. 40 years 1 / 40 x 100 2.5% per year

e. 5 years 1 / 5 x 100 20% per year

f. 4 years 1 / 4 x 100 25% per year

g. 20 years 1 / 20 x 100 5% per year
