What is the measure of the missing angle?
90°
600
7.

Answers

Answer:

30°

Step-by-step explanation:

Let the measure of the missing angle be x°

Therefore, by interior angle sum postulate of a triangle:

x + 60° + 90° = 180°

x + 150° = 180°

x = 180° - 150°

x = 30°

Thus the measure of the missing angle is 30°.

Answer:

C. 6 units

Step-by-step explanation:

It is a translation, so the length of the sides are not being affected since the entire shape is being moved.

Answer:

C. 6 units

Step-by-step explanation:

The second triangle is a translation of the first. A translation is a figure the slides up, down, left, right, etc. Essentially, it changes it's location.

A translation does not change it's size!

Therefore, it would still be the same length as AC, which was 6 units.

A quadrilateral has two angles that measure 10° and 70°. The other two angles are in a ratio of 3:11. What are the measures of those two angles?

Answers

Answer:

The measures of those two angles are 60° and 220°

Step-by-step explanation:

The sum of the measures of the angles of any quadrilateral is 360°

Let us solve the question

∵ A quadrilateral has two angles that measure 10° and 70°

→ By using the rule above, subtract their measure from 360

∴ The sum of the other two angles = 360° - 10° - 70°

∴ The sum of the other two angles = 280°

∵ The other two angles are in a ratio of 3: 11

→ Find the sum of the parts of the ratio

∵ The sum of the parts of the ratio = 3 + 11 = 14

∵ The sum of the measures of these 2 angles is 280°

→ By using the ratio method

→ m∠1 : m∠2   :  their sum

→ 3      :  11       :  14

→ x      :  y        :  280°

→ By using cross multiplication

∵ x × 14 = 3 × 280

∴ 14x = 840

→ Divide both sides by 14

∴ x = 60

∴ m∠1 = 60°

∵ y x 14 = 11 x 280

∴ 14y = 3080

→ Divide both sides by 14

∴ y = 220

∴ m∠2 = 220°

∴ The measures of those two angles are 60° and 220°

The chart below shows how many cups of lemonade Marcia sold each hour she had her lemonade stand set up. To make 10 cups of lemonade, Marcia has to squeeze 3 lemons. How many lemons did Marcia use in the first 4 hours?

Answers

Answer:

[tex]123\frac{1}{3}\ cups[/tex]

Step-by-step explanation:

Given

[tex]10\ cups = 3\ lemons[/tex]

See attachment for chart

Required:

Lemons used in first 4 hours

First, we calculate the number of lemon sold in the first 4 hours.

[tex]Lemon = 6 + 5 + 11 + 15[/tex]

[tex]Lemon= 37[/tex]

Represent the number of cups of lemonades needed with x

So, we have:

[tex]x = 37\ lemons[/tex]

and

[tex]10\ cups = 3\ lemons[/tex]

Cross Multiply:

[tex]x * 3 = 10 * 37[/tex]

[tex]3x = 370[/tex]

Make x the subject

[tex]\frac{3x}{3} = \frac{370}{3}[/tex]

[tex]x = \frac{370}{3}[/tex]

[tex]x = 123\frac{1}{3}[/tex] cups

Answers

Answer:

y = 2x +13

Step-by-step explanation:

1. find the slope by using the formula y2-y1

                                                             --------

                                                             x2-x1

which is

23 - 19           4

------------ =     ---   = 2

5-3                 2

2. finding the y intercept

so to find the y intercept you plug in the numbers to this formula

y-y1 = m (x-x1)

y - 19 = 2 (x -3)

y - 19 = 2x -6

  +19          +19

y = 2x +13

I’m not too sure of what the equation is but I made a guess let me know if this was the right equation please I can redo it.

But, when solving this equation you are trying to find the value of x. To do that you have to get rid of the 3.

You would either add or subtract the 3 on both sides.

When the three is gone you should have somthing like

x = 5
- 3

Which you would move on to subtract the 5-3 and get 2.

x= 2

Here’s a picture of how I solved it
