Classify the pair of angles.

O adjacent
O complementary
O supplementary
Onone of these

Answers

This is going to be none of these? For me it’s an acute but let me know what you think

The pair of angles are acute angles.

The correct option is none of these.

What is an angle?

The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.

Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.

We have,

The pair of angles of 30 and 30 are equal in measure.

But they are not adjacent, as they do not share a common vertex and a common side.

They are also not complementary, as complementary angles add up to 90 degrees, and 30 + 30 = 60.

Similarly, they are not supplementary, as supplementary angles add up to 180 degrees, and 30 + 30 = 60.

Therefore,

The pair of angles are none of the given options.

Challenge: Perla worked 4 hours at her job on Saturday and then spent $12.75, in the supermarket, on her way home. She worked 5 hours on Sunday and earned 1.5 times her normal hourly rate because it was a holiday. She spent $8.50, at the florist, on her way home on Sunday.

You have $75 and need to buy 9 books at the bookstore and each book costs d dollars.

​Write an algebraic expression to represent the amount of money left over.

Answers

Answer:

75-9d

Step-by-step explanation:

Hello,

The Answer to the question is 75-9d let me explain why,

you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.

You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.

75 - 9d

75 is the total. You need to subtract it by how many books your buying, 9.

The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs

Hope you can understand, I was having some trouble finding a way to explain it so my bad.

Also, I haven't done that in a while so sorry if I'm wrong

If £25 = 450 rubles, how many £ are in 864 rubles?

Answers

Answer:

£48

Step-by-step explanation:

£25 = 450 rubles

We need to know how many rubles you can get from £1.

£25 = 450

£ = 450/25

£ = 18

So, with £1 you get 18 rubles.

To know how many £'s you would need for 864 rubles, you need to divide 864 by 18.

£ = 864/18

£ = 48

3. What is the scale factor from the actual flower garden to the new scale drawing?

Be sure to express your ratio in simplest form.

Answers

Answer:

1.) Scale factor from the actual flower garden to the scale drawing = 20 : 1

2.) Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches

3.) Scale factor from the actual flower garden to the new scale drawing = 8:1

Step-by-step explanation:

Given - Penny’s backyard contains a flower garden. The dimensions of the

             actual garden are 5 feet by 7½ feet. A scale drawing of the flower

             garden is 3 inches by 4.5 inches.

To find - 1. What is the scale factor from the actual flower garden to the

                  scale drawing?

              2. If the drawing is enlarged by a scale factor of 5/2, what would    

                  be the dimensions of the flower garden in the new scale

                  drawing?

              3. What is the scale factor from the actual flower garden to the

                   new scale drawing?

Proof -

As we know that,

1 feet = 12 inches

⇒5 feet  = 5×12 = 60 inches

  7½ (= [tex]\frac{15}{2}[/tex]) feet = [tex]\frac{15}{2}[/tex]×12 = 90 inches

∴ we get

The dimensions of the actual garden is 60 inches by 90 inches.

1.)

As,

[tex]\frac{60}{3} = \frac{20}{1} = 20 : 1[/tex]

[tex]\frac{90}{4.5} = \frac{900}{45} =\frac{20}{1} = 20 : 1[/tex]

So,

Scale factor from the actual flower garden to the scale drawing = 20 : 1

2.)

As given,  If the drawing is enlarged by a scale factor of 5/2

⇒Dimensions of flower garden = 3×[tex]\frac{5}{2}[/tex] inches by [tex]4.5 (\frac{5}{2})[/tex] inches

                                                    = 7.5 inches by 11.25 inches

∴ we get

Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches

3.)

Scale factor from the actual flower garden to the new scale drawing = [tex]\frac{60}{7.5}[/tex] = [tex]\frac{600}{75} = \frac{8}{1} = 8 : 1[/tex]
