Answer:

the answer is B!

Step-by-step explanation:

i just took the exam!! 100 percent correct

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

I think you can manage to do the other two questions, if you need help let me know and I'm leaving the other questions to you as you should understand and try those questions alone. Still, I'm ready to help :)

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].

If the mean of the data set is 3.533. Then the mean absolute deviation for the data set will be 1.831.

Suppose the data specified is of n sized as

[tex]\rm x_1, x_2, \cdots , x_n[/tex]

Let this data's mean will be μ

Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.

It is calculated as:

[tex]\rm M.A.D = \dfrac{\sum_{i=1}^n|x_i - \mu|}{n}[/tex]

The data set is given below.

3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6

Then the mean of the data will be

Mean = (3 + 5 + 6 + 3 + 2  + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6)/15

Mean = 53/15

Mean = 3.533

Then the mean absolute deviation for the data set will be

[tex]\rm M.A.D = \dfrac{|3-3.533| + |5-3.533| + |6 - 3.533| + |3 - 3.533| + ...+|6-3.533|}{15}[/tex]

M.A.D. = 27.4665/15

M.A.D. = 1.831111

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]

Step-by-step explanation:

8 - 3 is 5

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:

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

Step-by-step explanation:

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

I will be showing both.

Cross Multiply:                                                   Decimal Form:

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

Step-by-step explanation:

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
