Answer:

8

Step-by-step explanation:

so they are one third of a pizza so thats 1/3 and 24 memebers so basically you just have to multiply 1/3 x 24 = 24/3 which is 8.

Answer:

8 pizzas should be ordered.

Step-by-step explanation:

To get the number of pizzas to be ordered, all we simple need to do is to multiply the numbers of the group members by the amount to be  consume by each group member. That is;

Number of pizzas to be ordered = amount to be consume by each group member × number of group members.

amount to be consume by each group member = [tex]\frac{1}{3}[/tex]

Number of group members = 24

We can now proceed to insert our values into the formula

Number of pizzas to be ordered = amount to be consume by each group member × number of group members.

Number of pizzas to be ordered =  [tex]\frac{1}{3}[/tex] × 24

                                                        = [tex]\frac{24}{3}[/tex]

                                                          = 8

Number of pizzas to be ordered = 8

Therefore, 8 pizzas should be ordered.

Answer:

3000 books

Step-by-step explanation:

We know the author receives a one time fee of $2500. On top of that, the author will receive $1.50 per book sold. This is a constant rate and is linear because of this. We can use y=mx+b. M is the slope or rate of change. M here is $1.50. B is the starting value which is $2500 here.

We write y=1.5x+2500.

This equation will give the amount of money the author earns for x number of books sold. If y=7000 for the author earning 7000. We will use inverse operations to isolate and find x.

7000=1.5x+2500

7000-2500=1.5x+2500-2500

4500=1.5x

4500/1.5=x

3000=x

Answer:

The author must sell 300 books.

Step-by-step explanation:

The total amount earned  = advance + books sold * money per book

We know they want to make 7000

The advance is 2500

They earn 1.50 for each book sold

b= number of books sold

Substituting in

7000= 2500 + 1.5b

Subtract 2500 from each side

7000-2500 = 2500-2500 + 1.5 b

4500 = 1.5 b

Divide each side by 1.5

4500/1.5 = 1.5b/1.5

3000 = b

Answer:

The popcorn buckets each cost around $15.34.

Step-by-step explanation:

Answer:

x - 1 and x + 2

Step-by-step explanation:

By the factor theorem if (x - a) is a factor then f(a) = 0.

Try x - 1:_

f(1) =  5(1)^3 + 8(1)^2 - 7 - 6

= 5 + 8 - 7 - 7

= 0  so x - 1 is a factor

We can find the other factors by long division:-

            5x^2  + 13x + 6

           -----------------------------------

x - 1 )    5x^3  + 8x^2  -  7x  -  6

           5x^3  -   5x^2

          --------------------

                        13x^2  -   7x

                         13x^2  -  13x

                         ------------------

                                       6x - 6

                                        6x - 6

                          -----------------

    5x^2  + 13x + 6   = (5x + 3)(x + 2)                          

The given radius is = 60 feet

The volume of the sphere is given by = [tex]\frac{4}{3} \pi r^{3}[/tex]

So we will find the volume of the sphere using radius as 60 and pi as 3.14

Volume = [tex]\frac{4}{3}*3.14*60*60*60[/tex] = 902059.20 cubic feet

As quarter of anything is defined as its one-fourth part, so here the volume of the quarter of sphere can be calculated by finding one fourth of the calculated volume.

So volume of quarter sphere = [tex]\frac{902059.20}{4}[/tex]

= 225514.80 cubic feet

And rounding this to nearest whole number we get 225515 cubic feet as the answer.

Adding the term 8x we will get:

x² + 8x + 4² = (x + 4)²

How to make a perfect square trinomial?

The perfect square trinomial is:

(a + b)² = a² + 2ab + b²

Here we start with:

x² + 16

We can rewrite this as:

x² + 4²

We can see that the term missing is the cross one, which will be:

2*(x)*4 = 8x

Then we will get:

x² + 8x + 4² = (x + 4)²

We are required to find the national debt in scientific notation. The scientific notation is used to represent either very small number or very large number.

I got a 100 on connections.

(1) 0.1992

(2)0.167

(3) 2/5

Step-by-step explanation:

The experimental probability of rolling a 1 on the next roll is 0.1992 (B). The theoretical probability of rolling a 3 on a six-sided die is 0.1667 (A). The odds of an event with a probability of 2/7 are 2 to 5 (D).

The experimental probability of rolling a 1 in this experiment is calculated by dividing the frequency of rolling a 1 by the total number of rolls. There were 245 occurrences of rolling a 1 out of 1230 total rolls. To find the experimental probability, you divide 245 by 1230, which gives you 0.1992.

Part B: The theoretical probability of rolling any particular number on a fair six-sided die is 1/6, because there are 6 possible outcomes and each outcome is equally likely if the die is fair. Therefore, the theoretical probability of rolling a 3 on the next roll is 0.1667 (which is equivalent to 1/6 when rounded to four decimal places).

When the probability of an event is 2/7, the odds of the event are 2 to 5 (not 2/5). This is because odds are expressed as the ratio of the number of successful outcomes to the number of unsuccessful outcomes. Since there are 2 chances of success and 5 chances of failure (7-2=5), the odds are 2 to 5.

Answer:

$6340

Step-by-step explanation:

First figure out what 6.5% of 4000 is by multiplying not dividing because dividing will give you a way bigger number.

4000 x 6.5%=260

260 x 9=2340

2340+4000=6340

The volume of the cube would be S^3, where S is the length of the side.

Volume = (5a + 4b)^3

Which becomes:

(5a+4b)(5a+4b)(5a+4b)  

Multiply the first two sets of parenthesis by each other:

(25a^2+40ab+16b^2)(5a+4b)  

Now multiply that by the 3rd set of parenthesis to get:

125a^3+300a^2b + 240ab^2 + b^3

Lily swam a 100-meter race, completing the first half in 27.8 seconds and the second half in 30.12 seconds. The difference between these times reveals that it took Lily about 2.32 seconds longer to swim the second half of the race compared to the first half.

The student, Lily, swam a 100-meter race with the first and second halves timed separately. She completed the first half in 27.8 seconds and the second half in 30.12 seconds. To find out how much longer it took her to swim the second half than the first, we need to subtract the first time from the second.

So, the calculation would be: 30.12 seconds (second half) - 27.8 seconds (first half) = 2.32 seconds. Therefore, it took Lily about 2.32 seconds longer to swim the second half of the race compared to the first half.

Answer:

Stu makes $338,263 over five years.  

Step-by-step explanation:

In order to find the total amount Stu would make after five years, you need to find out how much he will make each year based on the 2% increase.  Starting with year 1 at $65,000, we need to take his total salary and multiply by 1.02 (or the whole salary plus an increase of 2%).  So, in year 2, he would make $66,300.  Again, we would take his year 2 total salary and multiply by 1.02 to get $67,626 for year 3.  We apply these same steps to years four ($68,978.52) and five ($70,358.10).  To find his income over the five years, we need to add his salary from all five years together to get a total of $338,263.  

Answer:

Option C which is $ 338,263

Step-by-step explanation:

The salary for the first year = $65,000

Increase per year= 2 %

To find total money made in five years = ?

total earned in first year = $65,000

Total increase in money after first year = 2 % of 65,000

                                                                = [tex]\frac{2*65000}{100}[/tex]

                                                                 =$ 1300

Total earned in second year = 65,000 + 1300

                                                = $ 66,300

Total increase in money after second year = 2 % of 66,300

                                                                = [tex]\frac{2*66300}{100}[/tex]

                                                                 =$ 1326

Total earned in third year = 66300 + 1326

                                                = $ 67,626

Total increase in money after third year = 2 % of 67,626

                                                                = [tex]\frac{2*67626}{100}[/tex]

                                                                 =$ 1352.52

Total earned in fourth year = 67626 + 1352.52

                                                = $ 68978.52

Total increase in money after fourth year = 2 % of 68978.52

                                                                = [tex]\frac{2*68978.52}{100}[/tex]

                                                                 =$ 1379.58

Total earned in fifth year = 68978.52 + 1379.58

                                                = $ 70358.1

Total Made in all five years = 65000+66300+67626+68978.52+70358.1

                                             = $ 338262.62
