R = 6
1. What is constant of 4r - 0.9?
2. 6r , What is coefficient?
What is the variable?
3. r/2 , What is the coefficient?
4. r+r+r , What is the coefficient or r after the expression is simplified?
hi please help me lol i have no idea what this is
Answer:
coefficient: 7; constant: 2
Step-by-step explanation:
In a polynomial, a coefficient is a number that multiplies a variable.
The coefficient is 7.
A constant is a number by itself.
The constant is 2.
What is give an example of a unit rate used in a real world situation? Plz I'm literally so confused lol.
Answer:
Miles per hour. (mph)
Step-by-step explanation:
This can be used in almost everyday, since most people today drive around in cars, and use mph to see how fast they are going per hour.

Answer:
20 miles per hour
Step-by-step explanation:
An example would be like 50 beats per minute, or 20 miles an hour.
When rates are expressed as a quantity of 1.
2 horses ran from the same place from the at same time one horse ran at 2 miles per second and the other ran at a speed for 18 miles per second. how far apart were they in 1 minute? in 5 minutes? in 8 minutes?
- PLS HELP ASAP!!!!!
Answer:
1 minute = 1080 - 960 = 120 m
5 minutes = 5400 - 4800 = 600 m
8 minutes = 8640 - 7680 = 960 m
Step-by-step explanation:
I think the easiest way is to just see how far they get at each time. So I'm going to go one horse at a time.
16 m/s
1 minute = 60 seconds, every second is 16 meters so 16 m/s * 60 s = 960 m
5 minutes = 300 seconds so 16 m/s * 300 s = 4800 m
8 minutes = 480 seconds, 16 m/s * 480 s = 7680 m
I also want to point out that unites cancel out. m/s * s is kinda like variables so the seconds being multiplied by m/s cancels witht eh seconds in the denominator.
Now the next horse
18 m/s
1 minute totals to 1080 m
5 minutes = 5400 m
8 minutes = 8640 m
Now we take the differences of each time
1 minute = 1080 - 960 = 120 m
5 minutes = 5400 - 4800 = 600 m
8 minutes = 8640 - 7680 = 960 m
Another way to do this is to take the difference of speed and then multiply that by the time. so 18-16 = 2, then multiply each time by 2. For me it just makes more intuitive sense the way I showed.
The daily low temperatures in a city have been below 0° Fahrenheit (F) for the past two days. On Monday, the daily low temperature was −2℉ and on Tuesday, the daily low temperature was −7℉. What is the absolute value of the change in daily low temperatures between these two days, in degrees Fahrenheit?
(This is math class btw)
Answer:
5ºF is the absolute value of the change.
Step-by-step explanation:
Since absolute value is alwasy positive you will not need the negative sign. The difference between 7 and 2 is 5, so the answer is 5.
Ms. Chu gave her class 12 minutes to read. Ava read 5 1/2 pages in that time. At what rate in pages per hour did Ava read?
Plsssssss Helppp
Answer:
27.5 is correct
Step-by-step explanation:
what is the mean absolute deviation of the data set below?
3,1,4,4,4,1,1,2,1,5
Answer:
1.4
Step-by-step explanation:
Step 1: We have to find the mean of the data set
The mean is the average or the sum of all the numbers divided by the amount of numbers there are.
3 + 1 + 4 + 4 + 4 + 1 + 1 + 2 + 1 + 5 = 26
There are 10 numbers in total so, 26/10 = 2.6
Step 2: We now know the mean so now we have to find the deviation
3 - 2.6, |1 - 2.6|, 4 - 2.6, 4 - 2.6... so on, (Note: this is just finding the distance between the numbers and the mean)
The results are, 0.4 + 1.6 + 1.4 + 1.4 + 1.4 + 1.6 + 1.6 + 0.6 + 1.6 + 2.4
This is equal to 14
Step 3: Lastly, we have to find the mean of the deviations
We know the mean is 14
We have 10 numbers
Therefore, 14/10 = 1.4 is the MAD

Answer:
8b^2 + 9b + 3y +5
Step-by-step explanation:
7b + 8b^2 + 3 + y + 2b + 2y + 2
8b^2 + 9b + 3 + y + 2y + 2
8b^2 + 9b + 3y + 3 + 2
= 8b^2 + 9b + 3y +5
NOTE:
the symbol '^' represents 'to the power of', so 8b^2 would be 8b to the power of 2.
Max correctly solved this inequality.
StartFraction a over negative 5 EndFraction greater-than-or-equal-to 10. a less-than-or-equal-to negative 50.
Which graph matches the inequality?
A number line going from negative 55 to negative 45. An open circle is at negative 50. Everything to the left of the line is shaded.
A number line going from negative 55 to negative 45. A closed circle is at negative 50. Everything to the left of the line is shaded.
A number line going from negative 55 to negative 45. An open circle is at negative 50. Everything to the right of the line is shaded.
A number line going from negative 55 to negative 45. A closed circle is at negative 50. Everything to the right of the line is shaded.
Answer:
Answer:
See the graph attached. The red arrow represents the shaded area.
Explanation:
The inequality and its solution are given:
The solution set is all real numbers less than or equal to -50.
In a number line, the values less than -50 are all the values that are to the left of -50. Thus, the graph of a ≤ -50 must include -50 and the region to the left of it.
To indicate that - 50 is included, draw a solid point; then, shade the region since it to its left.
Please, see the graph attached. The red arrow represents the shaded area.
