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:

if the first term is 13, the second will be 13+x, the third 13+2x and so on, the tenth term will be 13+9x=40 9x = 27 x = 3 so the difference between the terms is 3 the sum of the first 10 terms is 13*10 + (x+2x+…+9x) = 130 + 45x = 130 + 45*3 = 130 + 135 = 265

We can either cross multiply or turn into decimal form to see if they have the same value.

I will be showing both.

We can conclude that 18/24 and 10/15 are not the same.

The amount of money seren had will be $132.

It is defined as the linear relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that:-

The solution will be done by making an equation:-

According to the first condition:-

S    +    V   =    $180

Now from the second condition:-

S   -   20   +   { ( v  +  20 ) / 4 ) }  =  180

Since   S   =   v  then:-

S   -    20   +    { ( S  +  20 ) / 4 ) } = 180

S  =   $132

Therefore the amount of money seren had will be $132.

Answer:

4 hours

Explanation:

[tex]\sf time = \dfrac{distance}{speed}[/tex]

Here the units are same for both, so no need of conversion.

Solve:

time taken = distance/speed

time taken = 320/80

time taken = 4 hours

Answer:

4 hours

Step-by-step explanation:

[tex]\text{Speed} =\frac{\text{distance} }{\text{time} }[/tex]

Then

[tex]\text{time} =\frac{\text{distance} }{\text{speed} }[/tex]

Then

[tex]\text{time} =\frac{\text{320} }{\text{80} } =4[/tex]

Answer:

A mixed fraction can be written as an improper fraction by multiplying the whole number with the fraction's denominator and adding that to the numerator, and finally writing that result on top of the denominator.

Step-by-step explanation:

Answer:

You have to multiply the whole number by the denominator and then add the answer you get with the numerator.

Step-by-step explanation:

For example, the fraction 10 [tex]\frac{1}{3}[/tex] is a mixed number right? So then you multiply 10x3=30. Then you add 30+1=31. So then the answer would be [tex]\frac{31}{3}[/tex].

The polar equation will be  [tex]r=\dfrac{4}{1+cos\theta}[/tex]

A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.

From the equation, we are told that

The  Eccentricity: e = 1

The  Directrix is   y = 4

Generally, the polar equation for e =  1  and y  =  + c is mathematically represented as

[tex]r =\dfrac{e\times c}{1+ecos\theta}[/tex]

[tex]r =\dfrac{1\times 4}{1+1\times cos\theta}[/tex]  

 [tex]r=\dfrac{4}{1+cos\theta}[/tex]

Therefore the polar equation will be  [tex]r=\dfrac{4}{1+cos\theta}[/tex]

Answer: The answer to 2, 6, 12, 16 is 9 and the answer to 5, 6, 12, 13 is 9

Step-by-step explanation: The mean of a set of numbers is another term for average. You add all of the numbers up like for example in the second set of numbers, 16+12+6+2 is equal to 36 and you then divide that sum by the amount of numbers you added which in this case is 4 so you get 36/4 which is equal to 9.

Mean of 2, 6, 12, 16 = (2 + 6 + 12 + 16) ÷ 4 = 36 ÷ 4 = 9

Mean of 5, 6, 12, 13 = (5 + 6 + 12 + 13) ÷ 4 = 36 ÷ 4 = 9

Answer: 3) volume= 28ft³

                   Surface area= 64ft

              4) Volume= 24mi²

                   Surface area= 192mi

Step-by-step explanation:

3) Volume= length x width x height

                = 7x2x2

                = 28ft³

    Surface area= [(2x2)x2]+[(7x2)x4]

                          = 8+56

                          =64ft

4) Volume= 1/2 x length x base x height (whenever finding the areas of triangular shapes you should multiply it by 1/2)

continuation;

               = 1/2 x 8 x 6  

               = 1/2 x 48

               = 24 mi³

Surface area= (1/2 x 8 x 6 x 2)+(6 x 6)+(10 x 6)+(8 x 6)

                    = 48 + 36 + 60 + 48

                    = 192 mi
