Answer:

$24=4k$

$k=6$

Step-by-step explanation:

For this exercise it is important to remember that "Times as great as" indicates multiplication.

Therefore, "4 times as great as" can be expressed as following:

$4k$

So, the statement "24 is 4 times as great as" indicates that 24 is equal to $4k$ .

Knowing this, you can write the following equation:

$24=4k$

In order to solve for "k", you can divide both sides of the equation by 4. Then, you get the following result:

$\frac{24}{4}=\frac{4k}{4}\\\\k=6$

Regal theater in Tikahtnu sold 548 tickets to Moana on Sunday. A adult's ticket was $6.50 while a child's ticket was $3.50. In t

Usimov [2.4K]

Answer:the number of adult tickets that were sold is 321

the number of adult tickets that were sold is 227

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of adult tickets that were sold.

Regal theater in Tikahtnu sold 548 tickets to Moana on Sunday. This means that

x + y = 548

A adult's ticket was $6.50 while a child's ticket was $3.50. In total, they took in $2881 in sales of these ticket. This means that

6.5x + 3.5y = 2881 - - - - - - - - -1

Substituting x = 548 - y into equation 1, it becomes

6.5(548 - y) + 3.5y = 2881

3562 - 6.5y + 3.5y = 2881

- 6.5y + 3.5y = 2881 - 3562

- 3y = - 681

y = - 681/-3 = 227

Substituting y = 227 into x = 548 - y, it becomes

x = 548 - 227 = 321

I am trying to find X and Y

son4ous [18]

I might just give two of them.
28. y=45°,
13x13=169
169/2=84.5
√84.5=x
x=2√21+√2/2
31. (5√2)²=50
50/2=25
x=√25=5
(5√2)²+(5√2)²=100
y=√100=10
Those are your answer.

7. Make a box-and-whisker plot for the data. What is the upper quartile value?

Nookie1986 [14]

In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.

42 43 47 48 51 52 56 56 58 60 62 64 65 66

Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64

+ 65 + 66) ÷ 14

Mean of the data = 770 ÷ 14

Mean of the data = 55

Median = (56 + 56) ÷ 2

Median = 112 ÷ 2

Median = 56

Lowest value = 42

Highest value = 66

Range = Highest value - Highest value

Range = 66 - 42

Range = 24

Lower Quartile = 25% of the data

Lower Quartile = 48

Upper Quartile = 75% of the data

Upper Quartile = 62

Lana71 [14]

Answer:

Peat's Pizza is is the one Tina should order from.

Step-by-step explanation:

If 4-pizzas from Peat's Pizza is 26 dollars, and she wants to order the 4 pizza special, Multiply 26 and 10 to get $260. Now if she wanted to order 4 times from Pizza Palace, which costs 75 dollars for 10 pizzas, Multiply the cost, 75, and the amount of times you want to order, to get the total cost. (Please tell me if I'm wrong! I'm trying to identify what I can.)
