Answer:

\boxed {\boxed {\sf (-1, -\frac{5}{2} )  \ or \ (-1, -2.5) }}

Step-by-step explanation:

We are asked to find the midpoint of a line segment. The midpoint bisects the line segment, or divides it into 2 equal parts. We find the midpoint by finding the average of the x-coordinates, then the y-coordinates.

( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

The endpoints are (-9, 3) and (7, -8). Match the value and the corresponding variable.

  • x₁= -9
  • y₁ = 3
  • x₂ = 7
  • y₂ = -8

Substitute the values into the formula.

(\frac {-9+7}{2},  \frac{3 + -8}{2})

Solve the numerators.

  • -9+7 = -2
  • 3+ -8 = -5

( \frac{-2}{2}, \frac {-5}{2} )

Divide.

(-1, - \frac{5}{2} )

The fraction can be written as a decimal.

(-1,-2.5)

The midpoint of the line segment is (-1, -5/2) or (-1, -2.5)

Answer:

Dilate, Reflect

Not congruent, dilations are used

Step-by-step explanation:

Dilate the figure by a scale factor of 1/3

Reflecting the resulting shape will map the figure

Step 1: Dilate by 1/3

Step 2: Reflect over the y-axis

Since dilations are used, the figures are not the same, as it changes area and side lengths.

If the question is how much Cody will jog to save ratio 4miles:3 miles
The ratio is \frac{3}{4}
We can just multiply 1 miles by ratio to see how much Cody will jog, so
1* \frac{3}{4} =\frac{3}{4} miles 
The result is \frac{3}{4} miles

Answer:

350.82

Step-by-step explanation:

To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.

The rectangle's area (lw):

7.21*14=100.94

The triangle's area (\frac{1}{2}bh):

\frac{1}{2} (6)(8)

\frac{1}{2} (48)=24

Now add up all the sides. (3 Rectangles, 2 Triangles.)

100.94 + 100.94 + 100.94 + 24 + 24

=350.82

The total surface area is 350.82 cm squared.
