The art teacher asked her students to cut out 1045 apples and 1463 leaves from construction paper five apples can be cut from a
PilotLPTM [1.2K]

From each construction paper number of apples can be cut = 5.

From a sheet of paper number of leaves can be cut = 7.

Let us assume number of construction paper required = x.

Therefore, x construction paper would cut out = 5x apples.

But we need to cut total 1045 apples.

Therefore, we can setup first equation as :

5x = 1045.

Dividing both sides by 5, we get

5x/5 = 1045/5

x=209.

Let us assume number of sheet of paper required = y.

Therefore, y number of sheet of paper would cut out = 7y.

But we need to cut total 1463 leaves.

Therefore, we can setup second equation as:

7y = 1463.

Dividing both sides by 7, we get

7y/7 = 1463/7

y = 209.

Therefore,

<h3>We got two equations 5x = 1045 and 7y = 1463.</h3><h3>From those equations we can get 209 construction paper and 209 sheets of paper required to cut out 1045 apples and 1463 leaves.</h3>

The end points of AB are A(2,2) and B(3,8). AB is dilated by a scale factor of 3.5 with the origin as the center of dilation to
disa [49]

Answer:

  • m = 6
  • length = 3.5√37

Step-by-step explanation:

Dilation does not change the slope, so it remains ...

  m = ∆y/∆x = (8-2)/(3-2) = 6/1

  m = 6

The length is multiplied by the dilation factor. The original length (d) is given by ...

  d = √((∆x)^2 +(∆y)^2) = √(1^2 +6^2) = √37

Then the dilated length is ...

  3.5d = 3.5√37 ≈ 21.290
