90. The original cost of a camera of a camera is 150 dollars, Now it decreased into 65 dollars. Let’s solve for the percent of decreased in the price of the camera. => 150 = 100% => 65 / 150 = .43 => .43 * 100% = 43%, 65 = 43% of the amount => 100% - 43% = 57% Thus, the price of the camera decreased for about 57% of the original price and now only costs 43% of the original price.

The deck off the back of the house creates a right triangle. The side of the deck resting against the house is the hypotenuse of
goblinko [34]

Approximately 2 gallons will be needed if each gallon of stain and  the project will cost be $73.96 if  each gallon costs $36.98

<h3>How to find the area of a triangle</h3>

The formula for calculating the area of a triangle is expressed as:

A = 0.5bh

where

base = 15feet

height = 20feet

Area of the deck = 20 * 15 * 0.5

Area of the deck is  150 square feet

Number of gallons needed  = 350/150 = 2.3

Hence approximately 2 gallons will be needed if each gallon of stain covers a maximum of 350 square feet.

Cost of the two gallons  = 36.98 * 2

Cost of the two gallons  = $73.96

Hence the project will cost be $73.96 if  each gallon costs $36.98

Complete the point-slope equation of the line through ( − 5 , 4 ) (−5,4)left parenthesis, minus, 5, comma, 4, right parenthesis
Tanzania [10]

The point slope form of equation through given points is:

y-6=\frac{1}{3}(x-1)

Step-by-step explanation:

Given points are:

(x1,y1) = (-5,4)

(x2,y2) = ((1,6)

First of all we have to find the slope of line

So,

m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{6-4}{1+5}\\=\frac{2}{6}\\=\frac{1}{3}

Point-slope form is given by:

y-y_1=m(x-x_1)

Putting m=1/3

y-y_1=\frac{1}{3}(x-x_1)

Putting (1,6) in the equation

y-6=\frac{1}{3}(x-1)

The point slope form of equation through given points is:

y-6=\frac{1}{3}(x-1)
