In the given figure, can you conclude r || s?

A. The lines are parallel because the given angles are same-side interior angles and their sum is 180°.

B. The lines are parallel because the given angels are alternate interior and they are supplementary.

C. The lines are not parallel because the given angles are corresponding angles and they do not have equal angle measures.

D. There is not enough information.

Answers

Answer:

The answer is C.

Step-by-step explanation:

The photo depicts corresponding angles (one angle above the other, as shown). When two lines are parallel, there will be corresponding angles that are the same measure. If they don't match, one line will be at a tilt and eventually intersect the other - therefore not parallel. Hope this helps!

Equation is used to show the relationship between two or more numbers and variables.

Cindy can clean the diner by herself in 2 hours while Emilia can do it by herself in 1.5 hours. Let t represent the time taken for both of them to clean. Hence:

(1/2 + 1/1.5)t = 1

t ≅ 52 minutes

If they start cleaning the diner at 6 am, they would  have enough time to clean before breakfast service

A rectangular prism has a length of 20 in., a width of 2 in., and a height of 314 in.

The prism is filled with cubes that have edge lengths of 14 in.

How many cubes are needed to fill the rectangular prism?

AAAAAAAAAAAAAAAAAAAAAAA I NEED HELPP

Answers

first solve the volume of the prism
V = l x w x h
where l is the length
w is the width
h is the hieght

V = 20 x 2 x 314
V = 12560 cu in

then solve the volume of the cube
V = e^3
V = 14^3
V = 2774 cu in

number of cube = 12560 / 2774
number of cube = 4 cubes

Answer:

• first find the volume of the rectangular prism:

[tex]{ \tt{volume = length \times height \times width}} \\ \\ \dashrightarrow \: { \tt{v = 20 \times 314 \times 2}} \\ \\ { \underline{ \tt{ \: \: volume = 12560 \: in {}^{3} \: \: }}}[/tex]

• find volume of the cubes:

[tex]{ \tt{volume = {side}^{3} }} \\ \\ { \tt{v = 14 {}^{3} }} \\ \\{ \underline{ \tt{ \: \: volume = 2744 \: {in}^{3} \: \: }}}[/tex]

• Therefore:

[tex]{ \tt{cubes = \frac{volume \: of \: prism}{volume \: of \: cubes} }} \\ \\ \dashrightarrow \:{ \tt{ \frac{12560}{2744} }} \\ \\ \dashrightarrow \: { \boxed{ \tt{ \: \: 4.58 \approx \: 5 \: cubes}}}[/tex]

Answers

Answer:

C or 8

Step-by-step explanation:

Once again, first you ant to simplify the equation before putting in the numbers.  So the simplified equation is mh + mp -p/h +m. Then you put the numbers in. mh is actually 3(-1), which is -3. mp is really 3*4, which is 12. p/h is 4/-1, which is -4, and then you add m. So when you put the numbers is it ends up as -3 + 12 - 4 +3, which simplified is 8, or C

8 because you have to do the work in the parentheses then go left to right

A circular garden has a diameter of 28 feet. The garden is to be covered with peat moss. If each bag of peat moss covers 160 feet square, how many bags of peat moss will be needed?

Answers

Answer:

15.39 bags or 16 bags

Step-by-step explanation:

To get the area of a circular garden, you use the following formula:

area = pi * r^2

Plug in r = 28 feet:

area = pi * 28^2

area = about 2463 square feet

Each bag covers 160 sq ft, so divide:

2463 sq ft / 160 sq ft per bag

= 15.39 bags

But you can't have a partial bag, so round up to:

16 bags

Jacob is painting a circular picture on his wall. If the painting
has a diameter of 4 ft, how much paint will he need to cover the
inside of the circle? Is this question asking you to find the area,
circumference, or neither?
A. area
B. neither
C. circumference

Answers

The answer is Area or A

The question is asking to find the amount of paint needed to cover the inside of the circular picture with a diameter of 4 ft. To determine the amount of paint required, we need to calculate the area of the circle.

The options provided are:

A. areaB. neitherC. circumference

Since we are calculating the amount of paint needed to cover the inside of the circle, the question is asking to find the area. Therefore, the correct answer is A. area.

The diameter of a circle is a straight line segment that passes through the center of the circle and connects two points on the circumference, effectively dividing the circle into two equal halves.

In the context of the given question, it states that the circular picture has a diameter of 4 ft. This means that the distance from one side of the circle to the other, passing through its center, measures 4 ft.

The diameter is an important measurement when calculating various properties of a circle, such as its area and circumference.

An instrument store has 20% clearance on every instrument. A guitar originally costs $120. You take it to the cashier and they charge a sales tax of 5%.

How much did you pay for the guitar?

Answers

Answer:

P = $100.80

Steps:

Price after clearance:

Pc = 120 - (120/100×20)

Pc = 120 - (1.2×20)

Pc = 120 - 24

Pc = 96

Price after sales tax:

P = Pc + (Pc/100×5)

P = 96 + (96/100×5)

P = 96 + (0.96×5)

P = 96 + 4.8

P = $100.80

Answer:

I’m pretty sure the answer would be $100.80

Step-by-step explanation:

1. Take the $120 and multiply by 0.20, which will give you 24 (that’s 20% of 120)

2. Subtract $120-$24= $96

3. There is a 5% sales tax so take 96 and multiply by 0.05 and you get 4.8

3. Add $96+$4.80= $100.80
