Answer:

Given points

  • A = (2, 1)
  • B = (4, 3)
  • C = (5, 3)
  • D = (6, 1)

<h3><u>Part (a)</u></h3>

See attached

<h3><u>Part (b)</u></h3>

Trapezoid

<h3><u>Part (c)</u></h3>

To dilate ABCD with a dilation center at (0,0) and a dilation factor of 4, multiply the x and y coordinates of ABCD by sf 4:

  • A' = (8, 4)
  • B' = (16, 12)
  • C' = (20, 12)
  • D' = (24, 4)

<h3><u>Part (d)</u></h3>

<u />\begin{aligned}\textsf{Area of Trapezoid}& =\dfrac{1}{2}(a+b)h\\\implies \textsf{Area of A'B'C'D'}& =\dfrac{1}{2}((x_{D'}-x_{A'})+(x_{C'}-x_{B'}))(y_{B'}-y_{A'})\\& = \dfrac{1}{2}((24-8)+(20-16))(12-4)\\& = \dfrac{1}{2}(20)(8)\\& = 80\: \sf units^2\end{aligned}

The ratio of black marker in a box to blue markers in a box is 3:5. If there are 10 more blue markers than black markers,how man
fiasKO [112]

Answer:

Total = 40

Step-by-step explanation:

Given

Black:Blue = 3:5

Blue = 10 + Black

Required

Determine the total number of markers

First, we need to determine the ratio of black to blue such that

Blue = 10 + Black

Black:Blue = 3:5

Multiply the ratio by 5

Black:Blue = 3 * 5 : 5 * 5

Black:Blue = 15 : 25

By direct comparison:

Black = 15

Blue = 25

The above shows that:

Blue = Black + 10

So:

Total = Black + Blue

Total = 25 + 15

Total = 40
