The figure is made up of two identical semicircles enclosed within a rectangle. Find the perimeter of the shaded region using 3.14

Answers

Answer:

61.74

Step-by-step explanation:

so u start off by solving for ghe semicircles.

the formula I wrote for it was:

1/2(3.14)(3)(3)=14.13

then i multiplied it by 2 because the other semicircle so you get:

28.26

then u find the area of the rectangle and subtract 28.26.

15x6=90

90-28.26=61.74

when 2 pipes fill a pool together, they can finish in 5 hrs. if one of the pipes fills half the pool then the other takes over the finishes filling the pool, it will take them 18 hrs. how long will it take each pipe to fill the pool if it were working alone?

Answers

Answer:

about 10 hrs each id say

Step-by-step explanation:

I just did 5 times two

The time taken to fill the pool if it were working alone is 18 hours.

What is multiplication?

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

The symbols cross (×), asterisk (*), and dot (·) are used to denote multiplication. You most frequently utilize the cross when writing in your notebooks. In computer languages and algebra, the asterisk and dot are both utilized (higher mathematics).

Given:

When 2 pipes fill a pool together, they can finish in 5 hrs,

One of the pipes fills half the pool then the other takes over to finish filling the pool, it will take them 18 hrs

1 / 2 of pool = 9 hrs as given

full pool = 9 × 2 = 18 hours

Therefore, The time taken to fill the pool if it were working alone is 18 hours.

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

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!

A) 0.91P
B) 1.09P

D) 15.09P

HELPPPPP PLEASEEEEE!!!!!

Answers

Answer:

The first question is A) P + 0.15P + 0.08P

The second question is B) 1.09P

Step-by-step explanation:

The cost of the dinner is the amount for the dinner, P plus the tax, 8% of P, which is 0.08P, plus the 15% tip, which is 0.15P

The cost of the car is P, or $15, plus the tax is 9%, or 0.09P

P + 0.09P = 1.09P

1st one is A because you wouldn't add them together first and you wouldn't subtract so that gets rid of B, C, and D.

2nd one is B, its really easy because you would just add 0.09 to the 1.00 to get 1.09

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]
