Answer 1

Answer:

Step-by-step explanation:

10). m(arc AB) = m(arc BC) = m(arc CA)    [given in the picture]

     m(arc AB) = [tex]\frac{360^0}{3}[/tex]

                      = 120°

     Therefore, m(arc ACB) = m(arc AC) + m(arc BC)

                                            = 120° + 120°

                                            = 240°

11). m(arc CD) = 127°  [Given]

    m(arc AB) = 51° [Given]

    m(arc AC) = m(arc BD) [Given]

    m(arc CD) + m(arc BD) + m(arc AB) + m(arc AC) = 360°

    127° + 2[m(arc BD)] + 51° = 360°

    178° + 2[m(arc BD)] = 360°

    2[m(arc BD)] = 360° - 178°

    m(arc BD) = 91°

    Since, m(arc CDB) = m(arc CD) + m(arc BD)

    Therefore, m(arc CDB) = 127°+ 91°

                                           = 218°

12). m(arc EH) + m(arc ED) + m(arc DH) = 360°

     180° + 53° + m(arc DH) =360°

     m(arc DH) = 360° - 233°

    m(arc DH) = 127°

Which value is closest to the perimeter of the window

Answers

Answer:

9.82 feet

Step-by-step explanation:

the perimeter of the window is the circumference of a semi-circle with a diameter of 5

P = (πd)/2     (divided in half because it's only half a circle)

P ≈ 3.14(3.5) which is approx 11

11 is closest to 9.82

Answer:

9.82 Is the Closest

Step-by-step explanation:

First of all, you can see its a half circle, meaning if we make it a full circle, the length of the center is 5, so the full circle's area is about 19.5-20. Now to find the area of the half circle/windows we get 9.75 - 10. The only number between that is 9.82, which should be you answer.

Answer:

substitute the value of y into the equation 7x+3y = 35

7x + 3(x+5) = 35 (distribute 3 through the parenthesis)

7x + 3x + 15 = 35

collect the like terms

7x + 3x = 35 - 15

10x = 20 (divide both sides by 10)

x = 2

substitute x = 2 into the equation y = x + 5

y = 2 + 5

y = 7

Answers

Step-by-step explanation:

a12 = 45 + (12-1)(-6)

= 45-66= -21

Step-by-step explanation:

yes, the other answer is correct.

just to explain a little bit more :

the sequence is clearly built by subtracting 6 from one element to the next.

in other words :

a1 = 45

a n = a n-1 - 6

in such a sequence you do the same operation/ calculation over and over again - once per new element.

the operation in this example is simple - as mentioned : subtract 6.

a1 just gives us a starting value (no operation done for for it) zu, the operation is done one time less than the running number of the element.

therefore, the general element generation algorithm/ formula is :

a n = a1 - (n-1)*6

The swimming pool shown below is a right prism with concave hexagonal bases. The owners of the pool want to paint the sides and bottom of the pool. If one gallon of paint covers 400 square feet, how many gallons of paint will be needed to paint the inside of the pool?

Answers

Answer:

2.21 gallons

Step-by-step explanation:

Area of sides:

2(10*3 + 1/2(14 + 10)*6) = 204 square feet

Area of the bottom:

20(3 + 10 + 5 + 10 + 6) = 680 square feet

Total area:

204 + 680 = 884 square feet

Paint needed:

884 / 400 = 2.21 gallons

Which equation should you solve to find x?
A. COS 26 = x/10
B. COS 26 = 9/10
C. Sin 26 = x/10
D. Tan 26 = 9/x

Answers

Answer: Choice C

sin(26) = x/10

===========================================================

Explanation:

With respect to the 26 degree angle, the x is the opposite side and the 9 is the length of the adjacent side.

We can say tan(26) = x/9 because tangent is the ratio of opposite over adjacent. In other words, tan(angle) = opposite/adjacent

Unfortunately, tan(26) = x/9 is not an answer choice.

Luckily though, we have other trig ratios to work with.

The sine ratio ties together the opposite side and hypotenuse

sin(angle) = opposite/hypotenuse

sin(26) = x/10

---------

Extra info (optional section)

Solving for x leads to...

sin(26) = x/10

10*sin(26) = x

x = 10*sin(26)

x = 4.38371 approximately

Also, note how cos(26) = 0.89879 approximately, which is fairly close to 9/10 = 0.9. This indicates some rounding error is going on when your teacher is displaying either the 9, the 10, or the 26 degree angle.

(x + 10) = (2x - 30).

Explain how a piece of food when eaten is digested and absorbed by the human body
PLS HURRY I NEED IT!!<3​

Answers

Answer:

The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

Answer & Explanation:

When humans chew food, it is chemically and physically broken down into smaller molecules. Your teeth physically crush the food and enzymes in your saliva break down the food into smaller pieces. Then your food goes through your esophagus and begins the digestion process. When the food reaches the stomach, the stomach walls pound the food to make it into smaller chunks of food. Hormones secreted in the stomach walls release acids and enzyme juices that chemically dissolve the food into even smaller pieces. The liver, pancreas, and gallbladder are major parts of the digestive process as well. They produce digestive juices and transfer bile to prepare for the next stage. After the food has been in the stomach for three hours, the food is now a liquid called chyme and is ready to move into the small intestine! The liver sends the bile to the gallbladder that secretes it into the duodenum. Then it dissolves the fats in the chyme so they can be digested by the juices from the pancreas and intestines. The enzyme juices break down the fat molecules in the chyme into fatty acids. The enzymes carry out the final deconstruction of proteins into amino acids. This happens in the small intestine lower region that is coated with villi. The villi maximizes molecule absorption and transfers it into the bloodstream. The blood then feeds it to the body’s organs and tissues.

That is whole process of digestion. Hope this helps! :3

Write an equation in slope-intercept form of the line that passes through (-1, 4) and (0, 2).
y =

Answers

Answer:

[tex]y=-2x+2[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (-1, 4) and (0, 2)

[tex]=\frac{2-4}{0-(-1)}\\=\frac{-2}{0+1}\\=\frac{-2}{1}\\= -2[/tex]

Therefore, the slope of the line is -2. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-2x+b[/tex]

2) Determine the y-intercept

[tex]y=-2x+b[/tex]

Recall that the y-intercept is the value of y when the line crosses the y-axis, meaning that the y-intercept occurs when x is equal to 0.

One of the given points is (0,2). Notice how y=2 when x=0. Therefore, the y-intercept of the line is 2.

Plug this back into the equation:

[tex]y=-2x+2[/tex]

Overnight, a pipe cracked and started to leak into a basement. The graph shows the depth of the water in relation to time.

___ inches.

​How deep is the water after four hours? The water is
__ inches deep.

​How long will it take for the water to reach a depth of 80 inches? It will take
__ hours.

Answers

Answer:

the water will rise 10 in each hour after 4 hours the water will be 40 in deep and it will take 8 hours for the water to reach a depth of 80 in

The water rises 10 inches each hour. The water is 4 inches deep is the water after four hours. It will take 8 hours for the water to reach a depth of 80 inches.

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

A pipe cracked overnight and started to leak into a basement.

The graph represents the depth (d) of the water over time (t).

As per the given graph, the required solution would be as:

Take two points (1, 10) and (5, 50) in the given graph

The linear function will be :

d - 10 = (50-10)/(5-1)(t - 1)

d - 10 = (40/4)(t - 1)

d = 10(t - 1) + 10

d = 10t - 10 + 10

d = 10t

Here slope of the given function is 10, which means 10 inches the water rise each hour.

The value of time (t) = 4 hr corresponds to the depth of water (d) is

d = 10(4) = 40

So, the water is 40 inches deep is the water after four hours

The value of depth of water (d) = 80 in corresponds to the time (t) is

80 = 10t

t = 80/10 = 8

So, It will take 8 hours for the water to reach a depth of 80 inches
