Item 1 The value of a car is $23,000. It loses 11.1% of its value every year. Find the approximate monthly decrease in value. Ro

IrinaK [193]

Answer:

Step-by-step explanation:

If the car loses 11.1% per year, we need to calculate how much money is that:

$23,000\frac{11.1}{100} = 2,553.$ ; this value is the lost per year.

Now, in order to calculate this loss per month, we divide it by 12:

$\frac{2553}{12} =212.75$

Hence, the monthly value decrease is $212.8, rounding it to the tenth.

(88 + 92 + 96 + x) / 4 = 90
(276 + x) / 4 = 90
276 + x = 90 * 4
276 + x = 360
x = 360 - 276
x = 84 <=== he would need an 84

Find the area of the figures.

levacccp [35]

Answer:

First one: 114

Second one: 64

Step-by-step explanation:

For the first one, you can break apart the shapes to a square and a rectangle

The square is 7 x 7 (12 - 5 = 7)

The rectangle is 13 x 5

The square is 49

The rectangle is 65

Add them together

The first one is 114

For the second one you can break it apart to a triangle and a rectangle

The rectangle is 4 x 12

The triangle is 0.5 * 8 * 4 [8 is 12 - 4 (base)]

The rectangle is 48

The triangle is 16

Add them together

48 + 16 = 64

The second one is 64

The linear equation that represent this situation is

$(300-50)x+(50)\frac{x}{2}=6,050$

Solve for x

$(250)x+(25)x=6,050$

$(275)x=6,050$

$x=6,050/275=\$22$
