Find the unit rate and answer the question. Only put the number of hours in as your answer. (Your answer will look something like this... 325)

Answers

Answer 1

rate :

distance/time225/375 miles/hr

======================

1 hours → 75 miles

? hours → (1125/75)

15 hours

It takes her 15 hours to drive 1125 miles.

Answer 2

Answer:

15 hours

Step-by-step explanation:

Finding how much distance in 1 hour

⇒ Ceci = 225 miles = 3 hours

⇒ 225 miles = 3 hours

⇒ 225/3 miles = 3/3 hours

⇒ (25 x 9)/3 miles = 1 hour

⇒ (25 x 3) miles = 1 hour

⇒ 75 miles = 1 hour

Finding how much hours in 1125 miles

⇒ 75 miles = 1 hour

⇒ 75x miles = 1125 miles = x hours

⇒ 75x/75 = 1125/75

⇒ x = 15

⇒ 75(15) miles = 1125 miles = (15) hours

⇒ 1125 miles = (15) hours

Please help!! It has to be *TWO* angles
{An angle measures 150° less than the measure of its supplementary angle. What is the measure of each angle?}

Answers

Answer:

165° & 15°

Step-by-step explanation:

Let the first angle be 'a'

second angle be (a-150°)

a+(a-150°) = 180°

2a=180°+150°

2a=330°

a=330/2

a=165°

first angle is 165°

second angle is 165-150=15°

165 and 15 and I know this because I did it

Answer:

opening a 300 page book to exactly page 143.

everyone in your school will get to school on time on the next school day.

Step-by-step explanation:

"Opening a 300 page book to exactly page 143" and "everyone in school will get to school on time next day" are the possible but unlikely events.

Unlikely event:

If something which probably will not happen and actually happens.

Certain event:

A certain event is an event that is sure to happen. E is a certain event if and only if P(E) = 1.

According to the given question

Opening a 300 page book to exactly page 143 is a random event and very unlikely to happen.A second grade classroom contains some books it is an event with high probability.Getting a 7 on a standard 6 sided number cube , it is an impossible event.Everyone in school will get to school on time on the next day is also a random event and very unlikely to happen.A triangle has 3 sides , it is a certain event.

Hence, first and fourth are possible but unlikely events.

Estimate the difference 7 3/4-2/25 Show your work.

Answers

Answer: 7 3/4 - 2/25 = 767/100 = 7 67/100 = 7.67

Step-by-step explanation:

Conversion a mixed number 7 3/4

to a improper fraction: 7 3/4 = 7 3/4 = 7 · 4 + 3/4= 28 + 3/4 = 31/4

To find a new numerator:

a) Multiply the whole number 7 by the denominator 4. Whole number 7 equally 7 * 4/4 = 28/4

b) Add the answer from previous step 28 to the numerator 3. New numerator is 28 + 3 = 31

c) Write a previous answer (new numerator 31) over the denominator 4.

Seven and three quarters is thirty-one quarters

Subtract: 31/4 - 2/25= 31 · 25/4 · 25 - 2 · 4/25 · 4 = 775/100 - 8/100 = 775 - 8/

100 = 767/100

The answer would be that 100 = 767/100 because you subtract the numbers at the end

Brett create a function of X with seven points each in a different location on the grid he graph sixth of the points as shown use the add point tool to show the location of a point that could be the seventh point of Brett function

Answers

Answer:

any point where x=3, 4, or 6.

Step-by-step explanation:

The thing that makes a function a function and not a relation is having only 1 y value per x value, which means if you draw a vertical line through a point, it should not intercept any other points. Basically, the main difference between a function and a relation is that a function can't have 2 points on top of each other.

Pick a point where x=3, 4, or 6. Those are the open spots on the grid with nothing above or below them. It doesn't matter which point you pick, as long as there is NOTHING directly above or below that point.

I hope you understood this solution. Happy mathing!

The solution is, any point where x=3, 4, or 6, is the location of a point that could be the seventh point of Brett function.

Kevin and Tiana are making soup. The recipe calls for a pound of onions. They have one onion that weighs ½ pound and another that weighs ⅖ pound. Kevin says they only have 3/7 pound of onions, so they definitely don’t have enough. Why is Kevin wrong?
PLSSSS HELP!

Answers

Kevin is wrong because adding fractions, you don’t add the numerator and the denominator on each one like you do when you are multiplying them, instead you have to find a common denominator, which is the lowest number that is a multiple of all of your denominators so in this case tej common denominator would be 10, so on the 2/5 fraction times the top and bottom by 2 so you get 4/10 and on the 1/2 fraction times the top and bottom by 5 to get 5/10 then you can add 4/10 and 5/10 to get 9/10 which cannot be simplified so Kevin and Tiana have 9/10 of a pound on onions

Ken, Leon, and Mark collect seashells as a hobby. Ken has (3x - 5) seashells, Leon has (2x + 1) seashells, and Mark has (0.25x + 7) seashells. a. Write an expression for the total number of seashells they collected. b. If the total number of seashells they collected is 45, determine the number of seashells each of them have.

Answers

Answer:

The answer:

Ken has 5 shells, Leon has 2 shells, Mark has 1.50 shells

how do we know:

because the 5 is negative we have -5 + -5=0 because negatives only go up by subtracting so 0+-5 is 5.

because the 1 is positive we can do 1+1 as were doing 2x1 so 1+1=2.

because we are doing 0.25x7 we need to know that we can flip the problem so we get 7x0.25. this makes things easy for you and me, we already know that 4 0.25's make 1 and we also know that 0.25+0.25 is 0.50 and 1 + 0.50 is 1.50 or just 1.5

Answer:

p < 8

Step-by-step explanation:

Let p = number of pounds of candy Lena will buy

Given:

Candy = $5 per poundLena will spend less than $40

Create an inequality using the given information:

⇒ 5p < 40

Solve the inequality:

⇒ 5p < 40

Divide both sides by 5

⇒ p < 8

The answer would be p > 8
The inequality to solve this would be 5p < 40
In the equation you are multiplying 5 by p, so you do the opposite and divide 5 and 40 by 5

5 divided by 5 cancels out, and 40 divided by 5 = 8. Take the leftover p and the < and make an inequality with 8. p < 8
