Answer:

At least 33 number of tickets can be sold in order to make a profit.

Step-by-step explanation:

Given:

A theater rents there space for $300 per night.

The company charges $9 per ticket.

Now, to find the least number of tickets that can be sold in order to make a profit.

Amount of rent per night = $300.

Charges of per ticket = $9.

So, to get the least number of tickets sold to get the profit we divide amount of rent per night by charges per ticket:

[tex]300\div9[/tex]

[tex]=33.33[/tex]

Thus, 33 tickets price is 33 × 9 = $297.

Therefore, at least 33 tickets can be sold in order to make a profit.

Mechanic A worked for 15 hours and mechanic B worked for 5 hours.

Step-by-step explanation:

Given,

Per hour charges of mechanic A = $95

Per hour charges of mechanic B = $75

Total hours worked = 20

Total amount charged = $1800

Let,

x represent the number of hours of mechanic A

y represent the number of hours of mechanic B

According to given statement;

x+y=20          Eqn 1

95x+75y=1800   Eqn 2

Multiplying Eqn 1 by 95

[tex]95(x+y=20)\\95x+95y=1900\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 2 from Eqn 3

[tex](95x+95y)-(95x+75y)=1900-1800\\95x+95y-95x-75y=100\\20y=100[/tex]

Dividing both sides by 20

[tex]\frac{20y}{20}=\frac{100}{20}\\y=5[/tex]

Putting y=5 in Eqn 1

[tex]x+5=20\\x=20-5\\x=15[/tex]

Mechanic A worked for 15 hours and mechanic B worked for 5 hours.

The first mechanic worked for 15 hours while the second mechanic worked for 5 hours.

Let's denote the number of hours worked by the first mechanic as x and the number of hours worked by the second mechanic as y.

We know two things:

⇒ x + y = 20

⇒ 95x + 75y = 1800

⇒ y = 20 - x

⇒ 95x + 75(20 - x) = 1800

⇒ 95x + 1500 - 75x = 1800

⇒ 20x + 1500 = 1800

⇒ 20x = 300

⇒ x = 15

⇒ y = 20 - 15 = 5

Thus, the second mechanic worked for 5 hours.

Complete question:

Two mechanics worked on a car. The first mechanic charged $95 per hour, and the second mechanic charged $75  per hour. The mechanics worked for a combined total of 20 hours, and together they charged a total of $1800. How long did each mechanic work?

Step-by-step explanation:

Answer:

The amount of butter used by baker this month is 294 kilograms.

Step-by-step explanation:

The amount of butter used last month by the baker = 210 kilograms

Now, according to the question:

The amount of butter used this month

= Previous months's amount +  40% of previous month's usage

Calculating 40% of 210 kg:

[tex]\frac{40}{100} \times 210 = 84[/tex]

⇒40% of 210 kilograms  = 84 kilograms

⇒ The amount of butter used this month  

= 210 kg +  84 kg = 294 kg

Hence,the amount of butter used by baker this month is 294 kilograms.

The baker used 40% more butter this month than last month. To find this month's usage, calculate 40% of last month's usage (84 kilograms) and add it to last month's usage. The baker used 294 kilograms of butter this month.

To answer this question, we can first calculate how much 40% of the butter used last month is. 40% of 210 kilograms is 84 kilograms. This is the amount of butter the baker used additionally this month than the previous month. If we add this to the amount of butter that was used last month (210 kilograms), we get the total amount of butter used this month. 210 kilograms + 84 kilograms = 294 kilograms. So the baker used 294 kilograms of butter this month.

Answer:

-13 》-21

Step-by-step explanation:

The reason why is because -21 is further away from 0 than -13. Negative numbers are greater when they are closer to 0, and less when further away.

The inequality that compares these two temperatures is - 13°F > - 21°F so

Northway Alaska is warmer.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, On a day in the month of February the temperature in Barrow Alaska is -21°F at the same time the temperature in Northway Alaska is -13°F.

We know 21 > 13 but - 13 > - 23.

Therefore the inequality that compares the temperature is - 13°F > - 21°F.

Final answer:

Maria and her sister's meal total cost is $13.60 before tip. With a 20% tip of $2.72 added, the total meal cost becomes $16.32.

Explanation:

First, we need to calculate the total cost of Maria and her sister's meal before tip. Each salad costs $5.40 and each drink costs $1.40. Given they both had a salad and a drink, we calculate the cost for each person as $5.40 + $1.40 = $6.80. Thus, for both Maria and her sister, the total cost of the meal is $6.80 x 2 = $13.60.

To calculate the total cost including a 20% tip, we first need to work out the amount of the tip. A 20% tip can be calculated by converting the percentage to a decimal (0.20) and multiplying it by the meal cost. So, the tip amount is 0.20 x $13.60 = $2.72.

Finally, to find the total cost of the meal including a 20% tip, we add the tip to the original meal cost: $13.60 + $2.72 = $16.32. Therefore, the total cost of the meal with a 20% tip is $16.32.

              8

          = 7/8

NOTE: To get 1 and 6, you find out how many times 8 can go in the l. c. m. and later multiplied the number of times by  the numerator which = 1.

Answer:

21 percent of their monthly income is budgeted for food.

Step-by-step explanation:

Given:

The Gonzalez family has a combined monthly income of $1850.

Their food budget is $380 per month.

Now, to find the percent of their monthly income is budgeted for food.

Total income = $1850.

Food budget = $380.

Now, to get the percent of the food budget:

[tex]\frac{380}{1850} \times 100[/tex]

[tex]=\frac{38000}{1850}[/tex]

[tex]=20.54\%.[/tex]

Thus, the percent nearest to whole = 21%.

Therefore, 21 percent of their monthly income is budgeted for food.

Answer:

40 grams of 40% sugar syrup

Step-by-step explanation:

It is 40g because you are adding 10g of sugar to 30g of syrup

It is 40 % syrup because you start out with 20% sugar in 30 g. That means the 1/5 of the syrup is sugar. That means that 6g is sugar. Then you add ten more grams of sugar. Now you have 16g of sugar in 40 grams of syrup.

Make equation to find percent

16/40=x/100

Step-by-step explanation:

4 + x = - 2x - 5 ( add 2x to both sides )

Y = 9

Step-by-step explanation:

2Y (with Y having a value of 9) would be equal to 2 x 9 which would give you 18

then you take the 18 and subtract 10x

which would give you 8x with the x not being relevant in your case (maybe)

To find the value of y in the equation 8 = 2y - 10x, rearrange the equation to isolate y. Divide both sides of the equation by 2, and the value of y is 4 + 5x.

To find the value of y, we need to isolate it on one side of the equation. First, let's rearrange the equation by moving the term with x to the other side:

8 + 10x = 2y

Next, let's divide both sides of the equation by 2 to solve for y:

(8 + 10x) / 2 = y

4 + 5x = y

So, the value of y is 4 + 5x.

-20+4=-16

-10-5=-15

=16/15

Final answer:

The rate of change between the points (5, -4) and (-10, -20) is found by calculating the slope, which is 16/15 or approximately 1.07.

Explanation:

To find the rate of change between two points, you can calculate the slope of the line that passes through them. The formula for the slope (Δy/Δx) is the difference in the y-coordinates divided by the difference in the x-coordinates of the two points.

Using the points (5, -4) and (-10, -20), we can substitute these into the slope formula:

Calculate the change in y (Δy): -20 - (-4) = -16.

Calculate the change in x (Δx): -10 - 5 = -15.

Divide the change in y by the change in x to find the slope: -16 / -15.

The slope of the line is therefore 16/15 or approximately 1.07.
