Students at Garcia Middle School took a survey about their favorite school.The results showed that 182 students rated pizza as their favorite food. This number represented 68% of the number of students who took the survey.What was the total number of students that took the survey?

Answers

Answer:

267.64 students

Step-by-step explanation:

Let the total number of students that took the survey be represented as x

This number represented 68% of the number of students who took the survey.

The results showed that 182 students rated pizza as their favorite food.

Therefore:

68% × x = 182 Students

68/100 × x = 182

68x/100 = 182

Cross Multiply

68x = 182 × 100

x = 182 × 100/68

x= 267.64705882 students

Therefore, the total number of students that took the survey is Approximately 267. 64 students

Answers

Answer:

8,910

Step-by-step explanation:

i just multiplied all the sides

and i got 8,910

Answer:

105 cm²

Step-by-step explanation:

The shape is composed of a rectangle and a triangle on the right side

area of rectangle = 15 × 6 = 90 cm²

The triangle has dimensions , base = (15 - 9) = 6 cm and height = (11 - 6) = 5 cm

area of triangle = [tex]\frac{1}{2}[/tex] × 6 × 5 = 3 × 5 = 15 cm²

Total area = 90 + 15 = 105 cm²

Which of the following are independent events?

randomly choosing a marble from a bag, replacing it, and choosing again reaching into your pocket and pulling out two dimes out of 20 coins

drawing a number from a hat, not replacing it, and then drawing a second number

rolling a number cube, rolling again, and trying to match the first roll

Answers

Answer:

randomly choosing a marble from a bag, replacing it, and choosing again

rolling a number cube, rolling again, and trying to match the first roll

Explanation:

In an independent event, getting a certain outcome once does not change the probability of getting the same outcome again.

The second option (about the coins) is NOT independent because if you pull out a dime on your first try, there are fewer dimes in your pocket and you are less likely to pull out a dime the second try. The third option (about drawing a number) is also NOT independent for the same reason: you don't put the number back into the hat after drawing it out, so there's fewer numbers the second time and the probability is different.

Answers

Answer:

Not apportionment

Step-by-step explanation:

Apportionment can be described as a way of sharing out or dividing out in the best fair method.

If a family of 10 leave the house at the same time and have to share just two bathrooms, the time allocation should not be based on age rather should be based on how early each person wakes up in the morning.

Answers

Answer:

Step-by-step explanation:

You are trying to find the values of two quantities, so you will need to set up a system of two equations in two variables. We'll call M the price of a movie and V the price of a video game.

The first month: 3 movies, 8 video games, $55. Let's translate this into algebra:

3M + 8V = 55

The second month: 5 movies, 2 video games, $18. Translated:

5M + 2V = 18

Solve that system of equations

Amaka buys 4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils. If a pencil cost #8, how much does a ruler cost?

Answers

Answer:  ruler cost $12

Step-by-step explanation:

step 1

Let cost of ruler  be represented as r

and cost of pencil be represented as p

we were given that

4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils which is expressed as

4r + p = 2r+ 4p

and cost of pencil= $8

therefore

sTEP 2--- Solving

4r+ 8 = 2r+ 4 x8

4r+ 8 = 2r+ 32

4r - 2r= 32-8

2r= 24

r= 24/2 = r= $12

An international company has 23,200 employees in one country. If this represents 26.7% of the company's employees, how many employees does it have in total?
Round your answer to the nearest whole number.

Answers

Answer:

Total number of employees = 86,891 employees

Step-by-step explanation:

Let

x = total number of employees

26.7% of x = 23,200

26.7/100 * x = 23,200

0.267 * x = 23,200

0.267x = 23,200

x = 23,200/0.267

x = 86,891.385767790

approximately 86,891 employees

Total number of employees = 86,891 employees

P and Q form a linear pair if m P=(7x-4) and m Q =(2x-5) find the measure of each angle

Answers

Answer:

Answer:

Angle P = 143º

Angle Q = 37º

Step-by-step explanation:

Linear pair means the angles add up to 180º

So, using this, set up the equation: 7x - 4 + 2x - 5 = 180

Combine Like Terms

9x - 9 = 180

Add on both sides

9x = 189

Divide

189/9 = 21

Substitute 21 for x

Angle P: 7(21) - 4

Angle Q: 2(21) - 5

The Grand Old Duke of York had 10 000 men. He lost 10% of them on way to the top of
the hill, and he lost 15% of the rest as he marched them back down the hill.
What percentage of the 10 000 men were still there when they reached the bottom of
the hill?

Answers

Answer:

76.5%

Step-by-step explanation:

He lost 10% of them on way to the top of the hill

10% of 10,000 men

= 0.1 * 10,000

= 1,000 men

Remaining men = 10,000 - 1,000

= 9,000 men

15% of the rest as he marched them back down the hill.

15% of 9,000 men

= 0.15 × 9000

= 1,350 men

Total men remaining = 9000 - 1,350

= 7,650 men

% remaining =

x% of 10000 men = 7,650

x/100 * 10,000 = 7,650

Cross product

10,000x =7,650 * 100

10,000x = 765,000

x = 765,000/10,000

= 76.5%

x = 76.5%
