What is the midpoints of a segment whose endpoints are (-3, 8) and (7, -2) ?
Sidana [21]
M = (\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})
M = (\frac{7 - (-3)}{2}, \frac{-2 + 8}{2})
M = (\frac{7 - 3}{2}, \frac{6}{2})
M = (\frac{4}{2}, 3)
M = (2, 3)

5. Yesterday your friend made 1 gallon of dark pink paint using the information in the table.
Oxana [17]

Our friend's mistake when wanting to make a new mixture of pink paint is that she is only going to add 2 parts of white paint, the correct formula would be 3.

<h3>How to calculate how much paint you need to make 3 gallons of Pink paint?</h3>

To mix 3 gallons of pink paint we must take into account the following information:

  • 1 gallon of pink paint is equal to 3 parts red paint and 1 part white paint.

To find out how many parts we need to prepare 3 gallons of pink paint we must multiply the mix values for a gallon by 3.

Red paint:

  • 3 x 3 = 9

White paint:

  • 1 x 3 = 3

Based on the above, we need to use 3 parts white paint and 9 parts red paint to make 3 gallons of pink paint.

Note: This question is incomplete because the graph is missing. Here is the graph.

Solve for x. Round to the nearest tenth of a degree, if necessary.​
MissTica

Answer:

x ≈ 54.8°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = \frac{opposite}{adjacent} = \frac{PQ}{QR} = \frac{7.1}{5} , then

x = tan^{-1} (\frac{7.1}{5} ) ≈ 54.8° ( to the nearest tenth )
