Question

Pooja writes the ratio x over 3 = y over 4 to help her increasethe size of a two - dimensional shape.if the new value of x is 15 units, what will be the value of y.

Answer 1

The image shows a table at a restaurant in the shape of a trapezoid. The restaurant owners want to determine if trapezoid tables will fit comfortably into the rest of the dining room. The owners make a scale drawing of the dining room and a scale drawing of the table. If the greatest length of the table is represented in the scale drawing by 1.5 feet, what will the length of the other sides of the table be? Write your answer in decimal form. (1 point)

Answer 2

Using cross-multiplication, we can write:

x/3 = y/4

Multiplying both sides by 3, we get:

x = 3y/4

Substituting x = 15, we have:

15 = 3y/4

Multiplying both sides by 4, we get:

60 = 3y

Dividing both sides by 3, we get:

y = 20

Therefore, if the new value of x is 15 units, the value of y will be 20 units.
