Answer:

131.88in

Step-by-step explanation:

C = 2πr

The radius of the circle is from center to the perimeter.

In this case the radius is 21in.

3.14 for pi

C = 2(21)(3.14)

C = 42(3.14)

C = 131.88in

Answer:

the answer for this question should be 131.88 because 21 is the radius and the radius is half of the diameter which is 42 because you need to multiply 21 times 2 getting an answer for the diameter but we use the formulas.

C=2 times 3.14 times 21= 131.88

C= 3.14 times 42=131.88

Answer:

451.61

Step-by-step explanation:

1) Set a linear equaion

[tex] \frac{98}{x} = \frac{21.70}{100} [/tex]

2) Cross multiply

[tex]21.70x = 98 \times 100[/tex]

3) Multiple the right side

[tex]21.70x = 9800[/tex]

4) Divide both side by 21.70

[tex] \frac{21.70x}{21.70} = \frac{9800}{21.70} [/tex]

5) Solve the linear equation

[tex]x = 451.6129032[/tex]

[tex]x≈451.61[/tex]

Then 21.70% of 451.61 is 98

Answer: A. The range of each round is the same.

Step-by-step explanation:

Below shows the total score for both rounds. As you can see the totals for both rounds are very close so their range is most likely the same.

Round 1

(2 x 2) + (3 x 3) + (4 x 2) + 5 = 26

   4             9             8

Round 2

(3 x 2) + (4 x 3) + (5 x 2) + 2 = 30

Answer:

See below

Step-by-step explanation:

7)  a rectangle   12 x 8 = 96

     plus semi-circle   1/2  pi r^2 = 1/2 pi 4^2 = 25.132

          total = 121.132 m^2

8)  Circle area = pi r^2

       large circle   pi * 2^2  = 4pi

            MINUS the smaller one   pi 1.5^2 = 2.25 pi

                    total = 1.75 pi = 5.498 in^2

9) Square area = 10 x 10 = 100

      minus circle  pi r^2 = 25pi      total = 21.46  ft^2

Answer:

A = 8cm

Answer:

A rectangular prism is a three-dimensional shape, having six faces, where all the faces (top, bottom, and lateral faces) of the prism are rectangles such that all the pairs of the opposite faces are congruent.?

Step-by-step explanation:

Is that what you wanted?? sorry if its not

The center is the median and/or mean of the data. And, the shape describes the type of graph.

There are many shapes data sets could show. One example would be asymmetric data set. In this case, both sides of the picture would look almost exactly or could be exactly (rarely) alike. In this case, the mean could be used as a measure of center.

When the data is skewed right or left, the pictorial representation of the data will show fewer data points on the side where it is skewed and more data on the opposite side. The tail will be longer on the right if it is skewed right and vice versa.

In skewed right data, the mean will be greater than the median, and if the data is skewed left, the mean will be less than the median. The mean is not the measure of the center when the data is skewed.

Answer:

Graph 3

Step-by-step explanation:

equation: y = mx + b → y = 1/3x - 4

- m is the slope (slope = rise / run):

- b is the y intercept (when x = 0): -4

Graph 1 is incorrect because the y-intercept is 1.5 on this graph when the equation is -4

Graph 2 is incorrect because the slope is 3 / 1, the rise is 3 and the run is 1

the correct equation for this graph is y = 3x - 4

Graph 3 is correct because the slope is 1/3, the rise is 1 and the run is 3

and the y intercept is -4

Graph 4 is incorrect because the y-intercept is not even shown

Answer:

r>6

Step-by-step explanation:

10<3r+3 x -3+1

Solve by distributing:

10<3r-9+1

Simplify the arithmetic:

10<3r-8

Simplify the arithmetic:

3r-8>10

Add  8 to both sides:

3r-8+8>10+8

Simplify the arithmetic:

3r>10+8

Simplify the arithmetic:

3r>18

Divide both sides by 3:

3r/3 > 18/3

Simplify the fraction:

r>18/3

Find the greatest common factor of the numerator and denominator:

r> 6x3/1x3

Factor out and cancel the greatest common factor:

r>6

Check the picture below.

well, the length of the tunnel is "h", now two 8 meters cars, that's 8+8=16 meters plus a 3 meter connector between them, that's 16 + 3 = 19 meters, can those two cars connected like so fit inside the tunnel? sure thing, "h" can fit 19 meters just fine.

Answer:

3/5+1/10=7/10

Step-by-step explanation:

Multiplying both sides of 3/5, we get a common denominator (6/10)

The adding the two together, we get 7/10.

Good luck! Hope this helps!

Answer:

LCD = 5  

3/5 *2 because the denominators must be equal so 6/10 + 1/10

Cindy's house and Jenny's house are 1.33 miles distant from each other.

Speed is defined as the rate at which an object is moving (covering a particular distance). It is a scalar quantity as it defines only the magnitude and not direction.

The SI derived unit for speed is meter per second (m/s).

Given,

Cindy leaves house at 9 am and reaches to jenny house at 10 am

Let the distance between Cindy and Jenny house is x

First, Cindy walks half way to jenny house = x/2

then Cindy take U-turn and walks half way to home = x/4

again Cindy take U-turn and reaches jenny house = 3x/4

Total distance walked by Cindy = x/2 + x/4+ 3x/4

                                                    = x/2 + x

                                                    = 3x/2

Speed of jenny is 2 miles per hour

She walks 3x/2 distance and reaches Jenny house in one hour

⇒ 3x/2 = 2

⇒ 3x = 4

⇒ x = 4/3

⇒ x = 1.33 miles

Hence, distance between Cindy's and jenny's house is 1.33 miles.

Answer:

Equal to

Step-by-step explanation:

Hello!

Let's simplify the left side:

Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.

Let's simplfy the right side:

Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.

So the inequality is 9 _ 9

Therefore the sign should be "=" as 9 is equal to 9.
