Answer:

b) 24 is the area

Explanation:

Formula area of triangle: (bxh)/2

Area of triangle:

A= 12 x 4= 48 ÷ 2= 24

Answer:

Step-by-step explanation:

Answer:

[tex]3) x = 12, \ y = \frac{x}{3} = \frac{12}{3} = 4[/tex]

[tex]4) x = 2 , \ y = 5x + 9 = ( 5 \times 2 ) + 9 = 10 + 9 = 19[/tex]

[tex]5. a ) Profit = Cost \ Price - Selling\ Price[/tex]

    Profit = P, Cost C,

    [tex]P = 0.50C - 75[/tex]

 [tex]b) Break \ even\ means \ zero \ profit[/tex]

    [tex]P = 0.50C - 75 \\\\0 = 0.50C - 75\\\\0.50C = 75\\\\C = \frac{75}{0.50} = 150[/tex]

Number of cups to break even is 150 cups.

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

[tex]3(x - 2) + 7x = \frac{1}{2} (6x - 2)[/tex]

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

[tex]3x - 6 + 7x = 3x - 1[/tex]

Now, we would shift all x terms to the left and all number terms to the right.

[tex]3x + 7x - 3x = - 1 + 6[/tex]

After simplifying, the final equation would be:

[tex]7x = 5[/tex]

This is a linear equation and it has one solution.

[tex]x = \frac{5}{7} [/tex]

Answer: Cheeseburger

Real explanation:

Minimum: 28

Lower quartile: 32.5

Median: 39

Upper quartile: 49.5

Maximum: 56

Interquartile range: 23.5

Answer:

Volume of hemisphere =

[tex] \frac{2}{3} \pi \: r {}^{3} [/tex]

Given volume =

[tex]18\pi \: cube[/tex]

[tex] \frac{2}{3} \times \frac{22}{7} \: {r}^{3} = 18 \times \frac{22}{7} [/tex]

So pi is there on both the sides so it will be cut from both LHS and RHS

[tex] \frac{2}{3} \times r {}^{3} = 18[/tex]

[tex]2 \times r {}^{3 } = 18 \times 3[/tex]

[tex]2 \times r {}^{3} = 54[/tex]

[tex]r {}^{3} = \frac{54}{2} [/tex]

[tex]r {}^{3} = 27[/tex]

[tex]r = 3[/tex]

Therefore value of r=3 inches

Answer:

3. 31

4. 6

5. 7

6. No  because the frequency table shows only ranges of times.

Step-by-step explanation:

3. Add up the number of students in each section of your table:

6 + 2 + 8 + 6 + 9 = 31

4. Only the first group ran under 9 minutes.

5. 8 students ran 1 mile in under 10 minutes (the first two sections)

15 students took 11 or more minutes to run 1 mile (the last 2 sections)

15 - 8 = 7

6. No, because the frequency table shows only ranges of times.

There are 31 students in PE class, 6 students ran 1 mile in under 9​ minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that​ distance and no student ran a mile in exactly 12​ minutes.

A branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data

A frequency distribution table is a method to organize the data given so that it makes it more meaningful and easier to understand.

The given frequency table

Time                  Number of students

8:00-8:59                     6

​9:00-9:59                     2

​10:00-10:59                  8

​11:00-11:59                    6

​12:00-12:59                  9

3. The number of students in the PE class

6+2+8+6+9

=31

4. Only the first group ran under 9 minutes which is 6 students

5.  8 students ran 1 mile in under 10 minutes

6+2=8

15 students took 11 or more minutes to run 1 mile

15 - 8 = 7

6. No, because the frequency table shows only ranges of times.

Hence there are 31 students in PE class, 6 students ran 1 mile in under 9​ minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that​ distance and no student ran a mile in exactly 12​ minutes.

Answer:

Subtract 675 by 800, and you will get 125

To get from 675 to 800, you will add 125 to 675

Answer:

125

Step-by-step explanation:

675+1+1+1+1+1+1+1

lol just kidding

If you subtract 800-675, you would get 125.

Also if you added 125 to 675, you would get 800.

So, there you have it :)

Answer:

x(x^2 + 6)

Step-by-step explanation:

We are to simplify -3x(x-4)-2x(x+3).  Begin by performing the indicated multiplication.  We get -3x^2 + 12x - 2x^2 - 6x.

Combining like terms, we get    -5x^2 + 6x, which is equivalent to

                                                       x(x^2 + 6)

Answer

=5x²+12x-6

Step-by-step explanation:

you multiply -3x(x-4)-2x(x+3)

=-3x²+12x-2x²-6
