Answer:
-30r + 15
Step-by-step explanation:
We have been given that
20(−1.5r+0.75)
Use the distributive property a(b+c)=ab+ac.
20×(−1.5r)+20×0.75
Multiplying, we get
-30r +15
These two are not like terms. Hence , we cannot combine them.
Therefore, we cannot simplify it more.
Hence, the simplified expression is -30r + 15

Allen is traveling 65 MPh. how many hours will it take for him to travel 585 miles?
It will take Allen approximately 9 hours to travel 585 miles at a speed of 65 miles per hour.
Explanation:To determine the time Allen will take to cover a distance of 585 miles while traveling at 65 miles per hour, the formula for time, which is distance divided by speed, is used. Using this formula: Time = Distance / Speed. In this case, Time = 585 miles / 65 miles per hour, which equals approximately 9 hours. This calculation is derived by dividing the total distance Allen needs to travel, which is 585 miles, by his speed of 65 miles per hour, giving us the time it will take for him to complete the journey.
This formula of time equals distance divided by speed is a fundamental concept in physics and helps calculate the time taken to cover a given distance at a certain speed. By dividing the distance of travel by the speed at which Allen is traveling, we get the time required for the journey.
Understanding the relationship between distance, speed, and time enables us to compute travel durations accurately. In this case, for Allen traveling at a constant speed of 65 miles per hour, dividing the total distance of 585 miles by his speed reveals that it will take him approximately 9 hours to reach his destination.

Today the ratio of Elinor's age to her mother's age is 3:8. After 15 years, the ratio will become 6:11. What is Elinor's age today?
Elinor's current age is determined by setting up a system of equations based on the given ratios of her age to her mother's age now and in 15 years. After solving these equations, it is found that Elinor is 12 years old today.
Explanation:Let's define Elinor's age as E and her mother's age as M. The problem states that the current ratio of Elinor's age to her mother's age is 3:8, so we can write the equation E/M = 3/8. This means 8E = 3M. After 15 years, the ratio of their ages will become 6:11, so the future ages can be expressed as (E + 15)/(M + 15) = 6/11. To solve the problem, we set up the system of equations:
8E = 3M11(E + 15) = 6(M + 15)First, solve one of the equations for M to find M in terms of E, and then substitute into the second equation to find Elinor's current age:
From 8E = 3M, express M as M = 8E/3Substitute M in the second equation: 11(E + 15) = 6((8E/3) + 15)Expand and solve for EAfter solving the equations, we find that Elinor's current age is determined to be 12 years old.
Elinor's current age can be calculated by setting up a system of equations using the given age ratios (3:8 now, 6:11 in 15 years). By expressing the mother's age in terms of Elinor's age and substituting into the equation for their future ages, we find that Elinor's current age is 15 years old.
Explanation:To find out Elinor's age today, we will first use the given ratios to set up two equations that represent the current ages and the ages in 15 years. Let's denote Elinor's current age as E and her mother's current age as M.
The first ratio given is 3:8, which translates to the equation E/M = 3/8. The second ratio, which will be after 15 years, is 6:11, so the respective equation becomes (E + 15) / (M + 15) = 6/11.
By cross-multiplying the first equation, we get 8E = 3M. We can call this Equation 1. From the second ratio, cross-multiplying gives us 11(E + 15) = 6(M + 15), which simplifies to 11E + 165 = 6M + 90. If we call this Equation 2, we now have a system of two equations to solve for E and M.
Using Equation 1, we can express M in terms of E, which is M = 8E/3. Substituting this into Equation 2, we have 11E + 165 = 6(8E/3) + 90, which simplifies to 11E + 165 = 16E + 90. When we isolate E, we get E = 15. Therefore, Elinor's current age is 15 years old.

Answer:
In functions, there can be more than one of the same output, but there cant be more than one of the same input.
Step-by-step explanation:
Let's look at table A.
Input Output
4 3
3 2
3 1
We have two 3's for our input.
Let's take a different approach to this if you don't understand.
Let's imagine we have a vending machine.
If you press the number 2 you get Doritos
If you press the number 4 you get Sprite
Though if you press the number 3 you could either get Cashews or Cheetos. If you paid for the Cheetos and you get Cashews, that wouldn't be good; Its like a guessing game.
So, therefore Table A is NOT correct, as two of our input's are the same number.
Now let's look at Table B
Input Output
1 3
3 5
5 7
All of our input's are different, which is good. Let's imagine the vending machine again.
Pressing number 1 gives us Doritos
Pressing number 3 gives us Barbecue Chips
Pressing number 5 gives us Kettle Chips.
We get what we pay for, which means, in this equation, if you input is number 1, we will have number 3 as our output, ect.
This table IS correct.
I think you can apply this procedure to the other two tables to determine which one is right :)

At the start of the week, you could complete 12 push-ups. By the end of the week, you could complete 17 push-ups. Which proportion could you use to find the percent increase in the number of push-ups you can complete
Answer:
The percentage increase is equal to [tex]41.67\%[/tex]
The proportion to find the percentage increase is equal to [tex]\frac{5}{12}*100[/tex]
Step-by-step explanation:
we know that
[tex]12\ push-ups[/tex] ------> represent the [tex]100\%[/tex]
The increase of push-ups is equal to
[tex]17-12=5\ push-ups[/tex]
by proportion
[tex]\frac{12}{100}\frac{push-ups}{\%} =\frac{5}{x}\frac{push-ups}{\%}\\ \\x=\frac{5}{12}*100\\ \\x=41.67\%[/tex]
The percentage increase is equal to [tex]41.67\%[/tex]
The proportion to find the percentage increase is equal to [tex]\frac{5}{12}*100[/tex]
