Answer:

48 tickets

Step-by-step explanation:

I just had this question on a test and got it right! So this is how i did it:

if the advance price is $4, and you sell 40 tickets in advance, you do 40 times 4.

40 x 4 = 160

so you subtract the $160 from 400 and then that brings you $240 dollars left.

*these 240 dollars will be tickets bought at the door*

to determine the amount of tickets that need to be bought left, you need to do 240 divided by 5.

and that will give you a total of:

a least amount of 48 tickets

The least number of tickets the club needs to sell at the door to reach the president’s goal, 48.

A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given that, Tickets to a play cost $4 in advance and $5 at the door. The theater club president wants to raise at least $400 from the ticket sales. If the club sells 40 tickets in advance,

Since, the cost if advance ticket is $4 and they already sold 40,

Therefore, collected cost = 4 × 40 = $160

Now, cost to collect yet = 400 - 160 = $240

Cost of tickets at the door = $5

Therefore, tickets to be sold to meet the goal = 240/5 = 48

Hence, the least number of tickets the club needs to sell at the door to reach the president’s goal, 48.

Hi there!

A valley farmer has 26 employees and he pays each of them $410 per week.

After paying them for one week he has $162 dollars left. We need to find how much money he had at first.

So the first step is to multiply $410 on 26 since he gives 410 dollars to each employee, which he has 26.

$410 · 26 = $10,660

So he had $10,660 before he paid the workers, but he still had $162 left. To find out his overall total of money he had we need to add $10,660 and $162 which will be $10,822.

The farmer had $10,822

Answer:

The answer would D.) 33.5 because 9.5+24 is 33.5 and since vertical distance is always an absolute value, it will never be a negative number.

The vertical distance between the top and bottom of the boat is calculated by summing the distances above and below the lake's surface, which total 33.5 feet, making option D correct.

To calculate this, we consider that the top deck of the boat is 9.5 feet above the surface of the lake, while the bottom of the boat is 24 feet below the surface. The total vertical distance would be the sum of these two values, as one needs to account for the entire distance the boat covers from top to bottom.

So, the calculation would be as follows: 9.5 feet + 24 feet = 33.5 feet. Therefore, the vertical distance between the top deck and the bottom of the boat is 33.5 feet. This makes option D the correct answer.

Answer:

$89.25

Step-by-step explanation:

If one week is 29.75, then you can infer that each week separately would be the same amount. With this information, you can form this equation:

y = 29.75x

X would be the number of weeks while y would be the final amount based off the number of weeks.

If you substitute x with 3, then you should get the final answer of 89.25.

4. The mean and median age are most likely to be same for the students in Math 1.

Step-by-step explanation:

We have been given two box plots that show the ages of college students in different math courses. We are asked to choose the true statement about these box plots.

1. The median age of the students in math 1 is greater than the median age of the students in math 2.  

We can see from our given box plots that median age for both Math 1 and Math 2 is 19 that is represented by vertical middle line of box, therefore, 1st statement is not true.

2. The median age of the students in math 1 is less than the median age of the students in math 2.

Since median ages for students in Math 1 and Math 2 are same (19), therefore, 2nd statement is not true.

3. The mean and median age are most likely same for both sets of data.

We can see that box plot for ages of Math 1 students is symmetric, therefore, both mean and median will be same for Math 1 students.

The box plot representing ages of Math 2 students is skewed right as it has an outlier as 23, therefore, its mean age will be greater than median age.

Therefore, 3rd statement is not true either.

4. The mean and median age are most likely to be same for the students in Math 1.

We can see that box plot representing ages for Math 1 students is symmetric and its whiskers are equidistant from median. So both mean and median age are same that is 19, therefore, 4th statement is true.

Answer: h=14

Step-by-step explanation:

7h-5(3h-8)=-72

7h-15h+40=-72 > I distributed the -5(3h-8) to get rid of parenthesis

-8h+40=-72 > I combined the like terms 7h-15h

-8h=-112 > I subtracted 40 from both sides

h=14 > I divided -8 from both sides

The solution is h = 14.

Given: Equation

7h - 5(3h - 8) = -72

Now, we will solve the equation for the value of h.

⇒ 7h - 5(3h - 8) = -72

⇒ 7h - 15h + 40 = -72

⇒ 7h - 15h = -72 - 40

⇒ -8h = -112

Dividing both sides by -8, we get:

⇒ h = 14

Therefore, the solution of the given equation is h = 14.

Answer:

Step-by-step explanation:

∠CAB = ∠DCA = 33° ( alternate angles )

∠ACB = 180 - 5x ( straight angle )

the sum of all 3 angles in a triangle = 180°, hence

33 + 180 - 5x + 2x = 180

- 3x + 213 = 180 ( subtract 213 from both sides )

- 3x = - 33 ( divide both sides by - 3 )

The inequality 20x ≤ 300 represents the number of 20-pound bags of soil a 300-pound capacity wheelbarrow can carry. Solving the inequality, we find x ≤ 15, meaning the wheelbarrow can carry up to 15 bags of soil without exceeding its weight limit.

To represent the problem as an inequality, let's say the number of bags of soil the wheelbarrow can carry is represented by x. Each bag of soil weighs 20 pounds, and the wheelbarrow can carry up to 300 pounds. So, the inequality would be 20x ≤ 300.

To solve the inequality, we divide both sides by 20: x ≤ 300/20. Therefore, x ≤ 15. This means the wheelbarrow can carry up to 15 bags of soil without exceeding its 300 pounds weight limit.

Final answer:

Plotting the integer 850 and its opposite involves marking the points on a coordinate system. The point 850 is plotted 8.5 units to the right of the origin, and its opposite, -850, is plotted 8.5 units to the left, assuming a scale where each unit represents 100.

Explanation:

To plot an integer and its opposite, let's use the number 850 and its opposite, -850, as an example. A plot in mathematics typically refers to marking points on the coordinate system, which consists of two intersecting lines, usually perpendicular, called axes. The horizontal axis is known as the x-axis, and the vertical axis is the y-axis.

To plot the integer 850, you first need to establish a scale suitable for the values you intend to plot. In this example, if each unit on your plot represents 100, then the point representing 850 would be placed 8.5 units to the right of the origin (0,0). Conversely, to plot the opposite of 850, which is -850, you would move 8.5 units to the left of the origin.

In coordinate form, the point 850 can be represented as (850,0), and its opposite, -850, would be (-850,0). This illustration shows how to plot integers and their opposites on a simple two-dimensional graph.
