Answer:

a. (5x+75)°

c. X° = 21° and (4x+75)°= 159°

Step-by-step explanation:

A. Combine like integers.

B. (5x+75)°=180° Because they are suplementary angles.

   5x°= 105°

   5x ÷5 = 105 ÷ 5

   x = 21

C. (4x + 75)°

   4(21) + 75

   84 + 75 = 159°

159 degrees is the answer

For each ordered pair,solve the percent problems to find the corridinates (x% of 31 is 3.317,4.407 is 39% of y)

Answers

Answer:

x=10.7, y=11300

Step-by-step explanation:

x%of 31 = 3.317

x/100×31=3.317

31x/100=3.317

31x= 3.317×100

x= 3.317 ×100/31

x =10.7

4407= 39% of y

4407= 39/100 × y

4407 =39y/100

4407×100=39y

4407 × 100/39=y

What is the surface area of the Triangular Prism rounded to the nearest tenth?
A)18.5
B) 36.9
C) 43.6
D) 87.2

Answers

Answer:

C. 43.6

Step-by-step explanation:

you need to take the area of each shape

lets do the skinny triangles first on the top and bottom of this shape.

so to find the formula of triangle we need to do 0.5 * 1.26 * 5.3

because the formula of a triangle is half the base times height.

so we get 0.5 * 1.26 * 5.3 = 3.339

multiply it by two and we get 6.678

now lets find the area of the huge rectangle on the back/behind of the shape

3.3*5.3 = 17.49

now lets find the area of the two smaller rectangles

3.3 * 3.6 = 11.88

2.3 * 3.3 = 7.59

now lets add

6.678 + 17.49 + 11.88 + 7.59 = 43.638

round it to 43.6

I think the answer is C. 43.6

baseball: mean absolute deviation of 3.5

soccer: mean absolute deviation of 1.2

In which sport were his scores the most spread out?


soccer

basketball

baseball

Answers

Answer:

basketball

Step-by-step explanation:

i took the test :)

Basketball have most spread out.

Option B is correct.

What is Standard Deviation?

A standard deviation (or σ) is a measure of how widely distributed the data is in reference to the mean. A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out.

We have

Basketball: mean absolute deviation of 4.6

Baseball: mean absolute deviation of 3.5

Soccer: mean absolute deviation of 1.2

As, a high mean absolute deviation tells us that many of the data values are spread out further from the mean.

Here Basketball have highest absolute deviation.

Thus, Basketball have most spread out.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

A dart is thrown at the board 100 times at random.

The number of times that dart hit the board is 40 times. Then the probability is calculated as,

Answers

Answer:

Radius: about 1.42 mm

Step-by-step explanation:

First, you divide the circumference (8.9) by 3.14, or π.

Cirucmference(8.9) divided by π(3.14) = the diameter (2.83439490446)

Diameter (2.83439490446) divided by 2 = radius (1.41719745223)

Now, you have to round to the nearest hundredth.

1.41719745223 rounded to the nearest hundredth is 1.42 because the second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

2. An amusement park just build a brand new Ferris wheel. But the Ferris wheel rolled 4 revolutions before coming to stop. The diameter of the Ferris wheel is 520 feet. What's the area of the circle? <----I'm not sure what was the question at the end I'm sorry but I think it was that.

Answers

Answer:

2. 212264

Step-by-step explanation:

Area of circle: 3.14(r^2)

we need to divide the 520 in half first

520/2 = 260

Now we do the equation!

3.14(260^2)

We get 212264 as our final answer :)

Havea great day!!

Please rate!!

I’m going to answer for 1

Since it’s 8,0 and 0,2 that means that the mid point is 4,1. You find the mid point because it’s the middle of the circle since the diameter would go from one point of a circle to another

The distance of the diameter is 8.25units
To find that you would do (x2-x1) which would equal -8 and (y2-y1) which would equal 2. -8^2 would be 64 and 2^2 would be 4. 64+4=68. The square root of 68 is about 8.25. 8.25 divided by 2~4.13

Now the area
A=pi*r^2
=3.14*4.13^2
=3.14*17.1
=53.7units2

So the coordinates of the center of the circle are (4,1) and the area of the circle is 53.7units2
