I came in super late
Allushta [10]

Since we know that 1/4 is equal to 25%, or 0.25 in decimal form, we are able to work with 0.75 in the expression.


We are told to use j as the original price of the jeans, so we can set up the expression:


j-0.25j


to represent the cost of the jeans with the discount.


Then to simplify, we simply take out j as a common factor, and solve what's in the parentheses:


j(1-0.25)


j(0.75) or 0.75j


Using this equation, we can solve for the b part of the question. If the pair of jeans originally costs $60, plug in 60 to where j is in the expression:


0.75j

0.75(60)=45


Therefore, the cost of the jeans after the discount is C) $45.

A semi- circle has an area of 35cm . What is its diameter?
patriot [66]

Answer:

<h2>Area Semicircle = 1/2 πr² </h2>

where

r radius of semicircle

→ ½ * 22/7 * r² = 35

→ 11/7 * r² = 35

→ r² = 35*7/11

→ r² = 245/11

→ r² = 22.77

→ r = √22.77

→ r = 4.77

Therefore,

Diameter = 2*4.77

= 9.54 cm

Fine the slope of the line perpendicular to the line graphed below
goldenfox [79]

Answer:

-\frac{1}{2}

Step-by-step explanation:

The slope of this line is 2 because the rise from one point is 2, and the run is 1. The change in y-value is divided by the change in the x-value which is 2/1, hence, the slope of the line being 2.

The slope of the line perpendicular to the one shown below will be -\frac{1}{2} because the slope that will result in a perpendicular line is the negative reciprocal of the original slope.
