Answer:

Step-by-step explanation:

The side is made up of two shapes, a rectangle and a triangle.

Area of the rectangle: 22.8 x 14.5 = 330.6

area of the triangle = (height = 26.5 - 14.5 = 12) 12 x 22.8 / 2 = 136.8

330.6 + 136.8 = 467.4

The total area that needs to be painted is 467.4 square feet

A gallon of paint costs $20 and covers 350 square feet.

The area that needs to be painted is more than 350 square feet, so we need two gallons of paint.

2 x 20 = $40 to paint the side once.

The cost of paint is $40

100 points gor correct answer Identify the base of a triangle in which h=(3x+15) ft and A=(15x+75) ft^2.

ivolga24 [154]

Answer:

b = 10

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the height )

Here h = 3x + 15 and A = 15x + 75, thus

$\frac{1}{2}$ × b × (3x + 15) = 15x + 75

Multiply both sides by 2 to clear the fraction

b(3x + 15) = 30x + 150

Divide both sides by (3x + 15)

b = $\frac{30x+150}{3x+15}$ ← factor numerator and denominator

= $\frac{30(x + 5)}{3(x+5)}$ ← cancel the factor (x + 5) on numerator/denominator

= $\frac{30}{3}$

= 10

The product of two consecutive negative integers is 600. What is the value of the lesser integer?

Misha Larkins [42]

Two consecutive negative integers are n and n+1. We are told that the product of these two integers is 600 so:

n(n+1)=600

n^2+n=600

n^2+n-600=0

n^2+25n-24n-600=0

n(n+25)-24(n+25)=0

(n-24)(n+25)=0, since we are told that n is negative...

n=-25

(...-25(-24)=600 so -25 is the value of the lesser integer)

Due to inflation, the price of an item increased by 45% and then dropped by 20%. By what percent did the price increase?

Marysya12 [62]

<u>Answer</u>:

Percentage of increase = 16%

===============================================

<u>Step-by-step explanation:</u>

Let the price of an item ⇒ x

When the price of the item increased by 45%, the price will be ⇒ 1.45 x

Then dropped by 20%

So, the final price will be ⇒ (1 - 0.2) * 1.45x = 0.8 * 1.45 x = 1.16 x

By comparing between the original price and the final price

The difference = 1.16 x - x = 0.16x

Percentage of increase = $\frac{1.16x}{x} *100=16$ %
