Which situation represents a proportional relationship? The cost of purchasing grapefruit for $1.80 per pound with a coupon for $1.00 off the total
cost
O
The cost of purchasing peaches for $7.00 per box of peaches with a delivery charge of
$3.00
The cost of purchasing a basket of oranges for $1.30 per pound plus $5.00 for the basket
O The cost of purchasing apples for $1.75 per pound plus a shipping fee of $0.16 per pound

I think its A) The cost of purchasing grapefruit for $1.80 per pound with a coupon for $1.00 off the total cost because a proportional has to be based or the same .

Step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

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.
