If 4 tickets to a show cost $9, find the cost of 14 tickets.

Answers

Answer:

$31.50

Step-by-step explanation:

You would divide 9/4 which gets you 2.25, then you multiply 14x2.25 to get 31.5

Answer:

31.50

Step-by-step explanation:

We can write a ratio to solve

4 tickets             14 tickets

----------------- = ------------------

9 dollars             x dollars

Using cross products

4x = 9*14

4x =126

Divide each side by 4

4x/4 = 126/4

x =31.50

Which of the following numbers is between - 3/4 and 5/8 ?

Answers

Answer:

I believe that the answer is -1/2

Step-by-step explanation:

The number which falls under the inequality -3/4 < x < 5/8 is when x = -1/2

The correct answer is Option D.

Given data:

The number x is between -3/4 and 5/8.

So, the inequality is -3/4 < x < 5/8.

When comparing fractions, we consider their relative positions based on their magnitudes. Starting from the left, -3/4 represents a point closer to negative infinity, followed by -1/2, and then 5/8, which is closer to positive infinity.

Visually, imagine the number line where -3/4 is to the left, 5/8 is to the right, and -1/2 is positioned between them. Since -1/2 is greater than -3/4 and less than 5/8, it falls within the specified range. The choice -1/2 satisfies the condition and can be identified as the number between -3/4 and 5/8.

Hence, the number is x = -1/2.

She collects data on the number of turkey sandwiches sold per day for a week. Explain to her how to find the mean, median, mode, and range of the number of turkey sandwiches sold. How that would be helpful when she orders new turkey sandwich makings? Which measure do you think would be the most helpful for her and why? ​​

Answers

Answer:

In order to find the mean of the sandwich shop you would add all of them up so 73+88+85+88+99+134+129 = 696. Then you divide it by how many days there are which there are 7 days so 696÷7=99.43. To find the median order the number least to greatest, then u count how many numbers are in the set. Count inwards and the median would be 88. The mode is the set of number that is in the problem the most, so in this case the mode would be 88. In order to find the range you subtract the highest number from the lowest number, so 134-73. The range would be 61. The measure that would be most helpful is the median, because it is not affected by the outliers!!

Answer: Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.

Step-by-step explanation: So for the top part your answer is supposed to be 4400.2 grams of protein in 7 weeks. You can get that by adding up the grams of protein for each type of food on the chart. Then you multiply that by 2 to get the amount they will be eating for 1 day which is 89.8. After that, because you have to solve for how much they will be eating for 7 weeks, you will have to multiply 89.9 x 49(days in total). To get you to the answer 4400.2. Now you have your answer for the second part of the problem. Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.

Katelyn has $1200.45 in her checking account. She spent $85.70 on groceries, paid her rent of $1000. Her grandmother sent her a check for her birthday for $85. How much money will be in Katelyn's account at the end of the month?

Answers

Answer:

$199.75

Step-by-step explanation:

Total money she has be x,

→ x = 1200.45 + 85

→ [ x = $1285.45 ]

Katelyn totally spend be y,

→ y = 85.70 + 1000

→ [ y = $1085.70 ]

Money left in Katelyn's account at the end of the month,

→ x - y

→ 1285.45 - 1085.70

→ $199.75

Hence, the money left is $199.75.
