Please help me! use the following set of data: 20, 28, 30, 6, 15,18, 21, 22, 25, 29, 24, and 26. What are the third and first quartiles of the data?

Answer:

Ok so basically, the formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

Answer:

The angle is 90 degrees since it is a right angle.

90-50=40 gives us how much the equation 6a-8 is worth

Set it so

6a-8=40

6a=48

a=8

Hope this helps and lmk if it  

Answer:

[tex]a=8[/tex]

Step-by-step explanation:

The total angle is 90° and 90° - 50° is 40° so [tex]6a-8=40[/tex].

After you add 8 to both sides you get [tex]6a=48[/tex].

Divide both sides by 6 and you get [tex]a=8[/tex].

For area, you multiply two sides together so it would be 15. For perimeter, you add up all sides so it would be 16.

Area = 15

Perimeter = 16

Answer:

16 is the perimeter and 15 is the area

Step-by-step explanation:

New bag of food will last until 2 1/2 weeks.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p : q = r : s or p/q = r/s

Given that,

Amount of food fed to Great Dane by Deon in 1 week = 62 cups

He has a new bag with 160 cups of dog food.

He needs this food to last up to 2 1/2 or 2.5 weeks.

We have,

Amount of food needed in 1 week = 62 cups

Let Amount of food needed in 2.5 weeks = x cups

Ratio of 1 week to 62 cups and 2.5 weeks to x cups will be equal.

So using proportional concept, we can write this as,

1 / 62 = 2.5 / x

We have to find the value of x.

Doing the cross multiplication,

x = 2.5 × 62 = 155 cups

So the amount of food needed in 2.5 weeks = 155 cups.

But he has a new bag with 160 cups which is more than enough for 2.5 weeks, since only 155 cups is needed for 2.5 weeks.

Hence the new bag of food will last until 2 1/2 weeks.

Answer:

1: 136, 2: 55. 3: 53, 4: 70, 5: 61, 6: 112

Step-by-step explanation:

The value of x for each indicated angle are 136, 55, 53, 70, 61, and 112.

The angles that are in the same position on a given two parallel lines intersected by a transversal line are called the corresponding angles.

Corresponding angles are always equal.

We can also have alternate angles which are always equal.

We can also have alternate interior and exterior angles which are equal.

The angles on the same side make upto 180 degrees

We have,

1)

x and 136 are alternate angles.

So,

x = 136

2)

125 and x make a straight angle.

So,

125 + x = 180

x = 180 - 125

x = 55

3)

53 and x are corresponding angles.

So,

x = 53

4)

x and 110 are exterior angles on the same side.

This means,

x + 110 = 180

x = 180 - 110

x = 70

5)

x and 61 are opposite angles.

This means,

x = 61

6)

x and 112 are alternate exterior angles.

So,

x = 112

Thus,

The value of x is 136, 55, 53, 70, 61, and 112.

Answer:

12 to a 100

Step-by-step explanation:

12% is basically 12/100

12% is equal to the ratio 12 to 100.

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

Here, we know that

 percentage = Quantity per unit 100

                12%  = 12 / 100

Thus, 12% is equal to the ratio 12 to 100.

Step-by-step explanation:

Answer:

18 1/12 ft = base length

Step-by-step explanation:

The area of a triangle of base b and height h is A = (1/2)(b)(h).

Since we want the measure of the base we solve this formula for b:

2A = (b)(h)

                                                                                                  2A

and then divide both sides to obtain a formula for b:  b = -----------

                                                                                                     h

Substituting 217 ft^2 for A and 24 ft for h, we get:

b = 2*217 ft^2 / 24 ft = 18.0833....  ft

If the answer must contain a fraction, take the 18 and hold it and convert the remaining 0.08333... to a fraction.  One way of doing this is to use a calculator.  On my old TI calculator, I would type in 0.0833333333..

and then press the MATH key and then select Option 1:  Decimal to fraction.

Doing this yields 1/12.  You can check this result by dividing:  1/12 = 0.08333...

Then the final answer, converted from 18.08333... ft, is

18 1/12 ft = base length

Step-by-step explanation:

Well its a supplementary angle if you add everything together.

We know theres a 90 degrees angle and a 34 degree angle.

90+34=124

124+4v=180

Since if you add everything up its a straight line

Solve the equation normally
