What's the answer to b = and c =

Answers

Answer 1

Answer:
b = 21°
c = 159°

Step-by-step explanation:

To solve for B we have to know that the opposite angle is the same. So 21° is the same as angle b.

To solve for C we have to know that a line adds up to 180°. So 21° plus c = 180

To find this we do 180 - 21 = 159.

I hope this helps you :D

Answer 2

Answer:

B = 21

C = 159

Step-by-step explanation:

As we are given 21 degrees as one of the angles, we can also notice that both lines are straight, so they are both adding up to an angle of 180 each.

To find C, we can use this equation:

C + 21 = 180

C = 180-21

C = 159

To find B, we can use this equation:

B + C = 180

Plug in C:

B + 159 = 180

B = 180-159

B = 21

Doug builds a skateboard ramp.The base is 6 feet long and the height is 1.5 feet.What is the slope of the ramp?Explain

Answers

Answer: The slope of the ramp is 0.25

Step-by-step explanation: The slope of a ramp is a measure of how steep it is. It is typically expressed as a ratio of the height to the length, also known as the rise over the run. To calculate the slope of the ramp, you can divide the height by the length.

In this case, the ramp is 6 feet long and 1.5 feet high, so the slope is:

1.5 feet / 6 feet = 0.25

So the slope of the ramp is 0.25, which can also be written as a fraction 1/4 or 25%. This means that for every four feet of horizontal distance, the ramp rises by one foot.

Alternatively, you can think of this as the angle of the ramp, if the angle formed by the ramp is small it will have a small slope and if the angle formed is large, it will have a large slope.

In simpler terms, the slope represents how steep the ramp is. The higher the slope, the steeper the ramp will be. And the lower the slope, the gentler the ramp will be. In this case, since the slope is 0.25 it is a gentle ramp.

Answer:

0.25

Answers

Answer:

79.99

Step-by-step explanation:

You divided 319.96 by 4 which gives you 79.99

Answer:

$ 79.99

Step-by-step explanation:

4 tires = $319.96

1 tire =$b

cross multiplying,

4× b = 1 × 319.96

→ 4b = 319.96

→ b = 319.96 ÷ 4

therefore b = $79.99

Answer:

= y + 3

Step-by-step explanation:

Group:

= 3.9y - 2.9y + 3

Add elements together:

= y + 3

3.9y + 3 - 2.9y

Arrange equation so that like terms are next to each other

3.9y - 2.9y + 3

Subtract.

1y + 3

Since 1y and 3 are not like terms, we cannot add them.

Therefore, 1y + 3 is the answer.
You can also write y +3.

It is not possible to form a polygon with side lengths of 6cm, 2cm, and 7cm. In order for a polygon to be possible, the sum of the interior angles must be less than 180 degrees. To form a polygon with 3 sides (triangle), the sum of the interior angles must be 180 degrees. But the sum of these side lengths does not add up to 180 degrees, therefore it's not possible to form a polygon with these side lengths.

Answer:

272.5

Step-by-step explanation:

dotted line of the circle = 12 because this whole thing is a parallelogram + half a circle. so diameter for the 1/2 circle is 12

so that means radius = 6, which is 1/2 of the diameter

circle area = π*r² = 36π

1/2 of it = 18π = 56.5

parallelogram area = base * height = 24 *9 =216

total 216+56.5

On the windowsill is a plant that is 8 inches tall. It is growing 2 inches per week. A second plant, which is 3 inches tall, is on the coffee table. It is growing 4 inches per week. Eventually the two plants will be the same height. How tall will the plants be?

Answers

Answer:

Let's call the height of the first plant as x and the height of the second plant as y.

We know that the first plant is 8 inches tall and growing 2 inches per week, so we can write the equation:

x = 8 + 2t (where t is the time in weeks)

We know that the second plant is 3 inches tall and growing 4 inches per week, so we can write the equation:

y = 3 + 4t

We also know that the two plants will be the same height when they meet, so we can set the two equations equal to each other:

x = y

8 + 2t = 3 + 4t

5 = 2t

t = 2.5

So the plants will be the same height in 2.5 weeks. To find out how tall they will be, we can plug this value of t back into either equation:

x = 8 + 2(2.5) = 8 + 5 = 13 inches

y = 3 + 4(2.5) = 3 + 10 = 13 inches

So both plants will be 13 inches tall when they reach the same height.

The table below shows the ratio of materials in a composting container.

Brown Material (gallons) 12.75 18.6 24 E
Green Material (gallons) 4.25 B D 11.5
Total (gallons) A C 32 46

If Jeremy needs 64 gallons of compost to plant his garden in the spring, how much brown material will he need? How much green material will he need?

Jeremy will need 52 gallons of brown material and 12 gallons of green material.
Jeremy will need 16 gallons of brown material and 48 gallons of green material.
Jeremy will need 12 gallons of brown material and 52 gallons of green material.
Jeremy will need 48 gallons of brown material and 16 gallons of green material.

Answers

Using proportions, the amounts needed of brown and green material for 52 gallons of compost are given as follows:

Brown material: 39 gallons.

Green material: 13 gallons.

What is a proportion?

A proportion is a fraction of a total amount, and in problems involving it, basic arithmetic operations such as multiplication or division are used along with the unit rates to find the equivalent measures.

On the first column of the table, the total amount is:

12.75 + 4.25 = 17 gallons.

The fractions of each material are given as follows:

Brown material: 12.75/17 = 0.75

Green material: 4.25/17 = 0.22.

Hence the amount of brown material needed with 52 gallons is:

0.75 x 52 = 39 gallons.

The amount of green material needed with 52 gallons is:

0.25 x 52 = 13 gallons.

what is the length of each side of a regular hexagon?

Answers

Answer: s = P ÷ 6

Step-by-step explanation:

The simplest, and by far most common, way of finding the length of a regular hexagon's sides is using the following formula: s = P ÷ 6, where P is the perimeter of the hexagon, and s is the length of any one of its sides.

Answer:

All the interior angles measure 120°. All the exterior angles measure 60°. Since all angles are equal in a regular hexagon, each angle is 120o and the sum of all the interior angles is 720o.
