Multiply. Write your answer as a fraction in simplest form.

5/6⋅(−4 1/2)⋅(−2 1/5)=

Answers

Answer 1

Answer:

7425

Step-by-step explanation:

First let's make the last two fractions improper.

-4  1/2 = -9/2    -2  1/5 = -11/5

Now we have to find the least common denominator.

[tex]\frac{5}{6} *\frac{-9}{2}*\frac{-11}{5}[/tex]

The least common denominator is 30 because all the denominators can be multiplied by something to get 30.

[tex](\frac{5}{5})*\frac{5}{6}* (\frac{15}{15})*\frac{-9}{2}* (\frac{6}{6})*\frac{-11}{5}[/tex] Simplify

[tex]\frac{25}{30}*\frac{-135}{30}*\frac{-66}{30}[/tex] simply

[tex]\frac{-3375}{30}*\frac{-66}{30}[/tex]

[tex]\frac{222750}{30}[/tex] simply

Can someone plz explain how to find the slope in a graph. I don't care if yall pick different numbers i just need to understand to find the slope. I learned this last year, but eng is making me learn it again this year, and i forgot how to find stuff. And im too dumb to know how to do it.

Answers

Answer:Using the Slope Equation

Pick two points on the line and determine their coordinates.

Determine the difference in y-coordinates of these two points (rise).

Determine the difference in x-coordinates for these two points (run).

Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).Step-by-step explanation:

The slope equals the rise divided by the run: Slope =riserun Slope = rise run . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.

5. Alani paid $8.50 to get in the movies. Before she left home her parents
gave her $20 to spend. If she bought candy that cost $3 each, how many
pieces of candy can she buy without going over the $20?

Answers

Answer:

3 peices

Step-by-step explanation:

Answer:

she can buy 3 pieces of candy

Step-by-step explanation:

1. subtract the price of the ticket from $20

  20 - 8.5 = 11.5

2. she has $11.50 left. divide that by the price of a piece of candy

  11.5 / 3 = 3.83

she cannot buy 0.83 of a piece of candy, so you round down to the nearest whole number, which is 3.

Answers

Answer:

There is a correlation between amount of time spent playing video games and memorization ability. There may or may not be causation. Further studies would have to be done to determine this.

Step-by-step explanation:

A piano instructor examined student progress. She noticed that when students spend less time playing video games, their memorization ability tends to increase. What can she conclude?

There is a correlation between amount of time spent playing video games and memorization ability. There may or may not be causation. Further studies would have to be done to determine this.

The piano instructor observes changes in the number of video games

played and its effects on the memorization ability.

What she can conclude is; A. There is no correlation

Reasons:

The aim of the experiment is to check if there is a correlation between the

time students spend playing video games and their memorization ability.

The observation made following a reduction in the time the student spend

playing video games and their memorization ability is that there is no

change in the memorization ability of student following a change in the

time spent playing video games.

The conclusion that can be made is that there is no relationship between

the time the student spends playing video games and their memorization

ability.

The time spent playing video game and memorization are not correlated.

Therefore, the correct option is; A. there is no correlation

Benito drew a graph representing the number of miles he ran and the number
calories he burned. What is the unit rate in calories per mile? 3 4 250 1,000

Answers

Answer:

250

Step-by-step explanation:

1000 divided by 4, is 250

The unit rate would be 250 calories per mile which is the slope of the given linear function.

What is the unit rate?

The unit rate of a linear function is defined as the slope of the linear function.

The slope is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

The given graph represents the number of miles he ran and the number of calories burned.

Taking two points as per the given graph :(2, 500), (6, 1500)

Let

x₁ = 2, y₁ = 500

x₂ = 6, y₂ = 1500

Substitute values in the formula to get

unit rate = (1500 - 500)/(6 - 2)

unit rate = (1000)/(4)

Apply the division operation,

unit rate = 250

Therefore, the unit rate would be 250 calories per mile

The population of pine bluff is 6791 and is decreasing at a rate of 7 per year.Write the linear equation that models this situation.

Answers

Answer:

y=15x+10

Step-by-step explanation:

The linear equation that models the situation is y = 6791 - 7x.

What is the slope-intercept form of a line?

The slope-intercept form of a line is y = mx +c where m is the slope of the line and c is the y-intercept

Given that, the population of pine bluff is 6791 and decreasing at a rate of 7 per year.

The population after x year is:
6791 - 7x

Now, if the population after x year is represented by y, then the equation is:

y = 6791- 7x

Hence, the linear equation that models the situation is y = 6791 - 7x.

Sally's soccer team played 25
games and won 17 of them.

What percent did the team LOSE?

Step-By-Step explanation please, I need to get this finished by tonight at 11:59 p.m!​

Answers

The team lost 32% of the games.

The team won 17/25 games. To find the number of games they lost, we would have to subtract 17 from 25. 25 - 17 = 8. This means the team lost 8/25 games. There are two ways I can think of. You can simply multiply 8/25 by 4/4 because 25 times 4 would equal 100. This would give you the percentage of 32. Another way is to write it like this: 8/25 = x/100. You would cross cancel to get 800 = 25(x) and divide both by 25. This would also give the answer of 32.
