Molli purchased 7 apples for $3.96. while looking at her receipt, molli dividedion & 3.96 by 7. why might molli perform this calculation a) in order to find the total number of apples purchased. b) in order to calculate the total amount that she owes. c) in order to calculate how much money she has left. d) in order to find out how much she paid per apple.

The correct option will be :  D) in order to find out how much she paid per apple.

Explanation

Suppose, the price of each apple is dollar.

So, the price of 7 apples will be : dollar.

Given that, Molli purchased 7 apples for $3.96 , this means.....

Here we can see that if we divide 3.96 by 7 , then we will get 'x' which is the price of each apple.

So, Molli perform that calculation  D) in order to find out how much she paid per apple.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
