Every New Year's Day, Jennifer brings 13 candies for each of her grandchildren and 20 more candies for the adults to share.
Let g represent the number of Jennifer's grandchildren and c represent the total number of candies she brings.

Find the value of c when g=9.

Answers

Answer:

We can use the given information to set up a system of two equations:

c = 13g + 20

c - 13g = 20

The second equation is obtained from the first equation by subtracting 13g from both sides.

To solve this system, we can use substitution.

First, we solve the second equation for c.

c = 20 + 13g

Then, we substitute this expression for c into the first equation.

20 + 13g = 13g + 20

Then, we simplify.

20 = 20

So, the value of c when g = 9 is 20 + 13 * 9 = 20 + 117 = 137.

Step-by-step explanation:

C=137 because if you use the equation 13(7) + 20 you will get 137 candies.

An hour before showtime, only 198 people are seated for a movie. According to ticket sales, 94% of the people have yet to arrive. How many tickets were sold for the movie? Explain your thinking

Answers

If 94% haven't arrived yet then the 198 people is 6% of the total.

To find the total people divide the number of people who have arrived by the percentage.

Total people = 198/6% = 198/0.06 = 3300

Total people = 3,300

Answer:

I think musiclover10045 is correct and the answer is 3300

Step-by-step explanation:

They had divided 198/0.06 to get 3300. I agree with this equation and the end product.

a) Windows on the International Space Station are shown below. Suppose the long base of the window is 15.2 feet and the short base is 11.2 feet. The perpendicular height from one base to the other base is 8.4 feet. Draw one of the trapezoid-shaped windows on grid paper and label its dimensions. Describe the process you would use to find the area of one trapezoid-shaped window. (2 points)

Area of trapezoids = (base 1 + base 2) × (height ÷ 2)

(15.2 + 11.2) × (8.4 ÷ 2) = 110.88

The area is 110.88 feet²

b) Calculate the area of the window using the dimensions given in Part A. Show your work and explain your reasoning. (4 points)

Answers

Answer:

Step-by-step explanation:

Area of trapezoids = (base 1 + base 2) × (height ÷ 2)

(15.2 + 11.2) × (8.4 ÷ 2) = 110.88

The area is 110.88 feet²

Kado spent 1 2/3 hours painting a fence. Then he spent 4/5 of an hour walking his dog. How much longer did he spend painting than walking? Orleans chose C as the correct answer.How did she get that answer?

Answers

Answer: B, 13/15

Step-by-step explanation: If you multiply both to 15, you will get 1 10/15 and 12/15 if you then subtract the two of them you will be left with

13/15.

Orleans might have got the answer from subtracting wrong or adding them together.

Hope this helps! :)

Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.

To find out how much longer Kado spent painting than walking his dog, we need to calculate the difference between the time he spent painting and the time he spent walking his dog.

Kado spent 1 2/3 hours painting the fence.

He spent 4/5 of an hour walking his dog.

To make the calculation easier, let's convert 1 2/3 hours into an improper fraction:

1 2/3 = (3*1 + 2)/3 = 5/3 hours

Now, the time difference is:

Time spent painting - Time spent walking

= (5/3) - (4/5)

To subtract fractions, we need to find a common denominator, which in this case is 15 (the least common multiple of 3 and 5):

= (5/3)(5/5) - (4/5)(3/3)

= 25/15 - 12/15

Now, we can subtract the fractions:

= (25 - 12)/15

= 13/15 hours

Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.

Should kids be allowed to pass on gym class?Lawmakers in Florida want kids to get moving. Back in 2009, the state began requiring middle school students to take a semester of physical education (PE) each year. But thousands of kids arent sweating this law. Students may opt out of gym class with a note from a parent.In some middle schools, more than one-third of students are choosing to skip PE, according to preliminary data from the Florida Department of Education. Many of those students are instead taking classes in the fine arts, such as drama or music. Others are using the time to get extra help with math or reading. Some people say its OK to pass on PE as long as kids are getting exercise outside school.Others say gym class is needed to address some unhealthy statistics. Obesity rates for kids ages 12 to 19 have tripled since 1980, according to the Centers for Disease Control and Prevention. PE proponents say students who learn to lead active lifestyles will keep those healthy habits with them as they become adults.Student reporters Gray Robertson and Destiny Cuevas line up on opposite sides of the gym class debate.Jump Into Gym!Should kids be allowed to opt out of gym classes? Absolutely not! PE is a great way to get and stay healthy. It gives you a chance to burn off calories. In some cases, it might be the only exercise kids get each day. The problem of obesity has infected our society. PE is a great way to fight that troubling trend.PE is also fun.
