Y and x have a proportional relationship and y=9 when x=2 what is the value of y when x=3

If they are proportional, then y/x should always be the same.

So 9/2= 4.5

We need to find the y value at x=3 to make y/x equal 4.5

4.5 = y/3

y = 4.5*3 = 13.5

slega [8]

Answer:

102.222 square yards of light.

Step-by-step explanation:

From the above question, the yard had the dimensions 40 feet long and 23 feet wide.

Hence, the yard is rectangular in shape.

We have to find the area of the yard.

The formula is given as:

Area = Length × Width

= 40 feet × 23 feet

= 920 square feet

Converting to yards

1 square foot = 0.111 square yard

920 square feet = x

Cross Multiply

x = 920 × 0.111 square yard

x = 102.222 square yards.

Therefore, Robbert would need 102.222 square yards of light.

The length of Chen’s office is 15.5 feet and the width is 7.8 feet. Use the formula p=2l + 2w to find the perimeter of the offic
solniwko [45]

Answer:

P = 46.6 feet

Step-by-step explanation:

P = 2L + 2W, where P is perimeter, L is length, and W is width.

2 x Length (L) = 2 x 15.5 feet = 31 feet;

2 x Width (W) = 2 x 7.8 feet = 15.6 feet.

Add both length and width together:

2L + 2W = 30.1 + 15.6 = 46.6 feet.

The perimeter (P) = 46.6 feet.
