Keith reads 48 chapters of a book in 6 hours.
What is his rate in chapters per hour?
Answer:
Keith's rate in chapters per hour is 8.
Step-by-step explanation:
Divide his 48 chapters by the 6 hours he read and in total it will be a ratio of 8 chapters to one hour.
Keith's rate in chapters per hour will be 8.
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
We are given that Keith reads 48 chapters of a book in 6 hours.
Therefore,
We need to Divide his 48 chapters by the 6 hours he read
48/6
= 8
Hence, in total it will be a ratio of 8 chapters to one hour.

Find n so that mean of the data set is 140. (120, 145, 130, 80, 95, 100, 340, n)
Answer:
Answer: n is 110
Step-by-step explanation:
Formular:
[tex]mean = \frac{ \sum(n_{1}, \: n _{2}, \: ...n_{n} ) }{n} \\ [/tex]
therefore:
[tex]140 = \frac{(120 + 145 + 130 + 80 + 95 + 100 + 340 + n)}{8} \\ \\ (8 \times 140) = 1010 + n \\ 1010 + n = 1120 \\ n = 1120 - 1010 \\ n = 110[/tex]

Which statement best defines work?
1. work is the time it takes to move an object once acted upon by a force.
2. work occurs when balanced forces act on a object and cause movement in the direction of these forces.
3. Work occurs when a force causes motion of an object, and this motion is in the same direction of the applied force.
4. Work is the distance over time that an object moves once acted on by a force.

Answer:
Yes
Step-by-step explanation:
Cross multiply
6/9 = 10/15
6 x 15 = 90
10 × 9 = 90
so yes they consist of equivalent fractions. cross multiplying is a simple way to find out if fractions are equivalent.
Anyone know how to do this
Answer:
Look in explanation
Step-by-step explanation:
I will assume that you're trying to solve for "x".
For number 1: 49+(5x+1) is a supplementary angle(180 degrees) so you can subtract 180-49 to get 131.
Now, 131 = 5x+1
-1 -1
130 = 5x
/5 /5
Now, we isolate the x to get x=26.
Number 2: There is a supplementary angle as well so we can put 5x+12+6x+3=180.
Now, combine the like terms to get 11x+15=180 so we now isolate x.
-15 -15
11x=165
/11 /11
x=15
Now, try the rest and set the terms to 180.
5x+1+8+4x=180
2x+1+x-10=180
6+x+5x=180
x+2+153=180(This is similar to #1)

We are supposed to factor this cube sum. I will give 100 points and brainliest to anybody that answers this with a VERY detailed explanation.
Answer:
y(y² + 1)(y² - y - 1)(y² + y - 1)Step-by-step explanation:
y⁷ + y = y(y⁶ + 1) = y((y²)³ + 1³) = y(y² + 1)(y⁴ - y² + 1) = y(y² + 1)(y⁴ - 2y² + 1 - y²) = y(y² + 1)((y² - 1)² - y²) = y(y² + 1)(y² - y - 1)(y² + y - 1)Used identities:
a³ + b³ = (a + b)(a² - ab + b²)a² - b² = (a + b)(a - b)a² - 2ab + b² = (a - b)²Algebra
= y⁷ + y
= y(y⁶ + 1³)
= y(y² + 1)(y⁴ - 2y² + 1 - y²)
= y(y² + 1)(y² - y - 1)(y² - y - 1)

Answer:
JH = 15
Step-by-step explanation:
KJ = 10
KI = 14
IH = 11
JH = ?
In order to find JH, we need to find JI, then add it to IH, which is 11. Here's the equation:
JH = JI + 11
In order to find JI, we need to subtract KJ from KI. Here's the equation:
14(KI) - 10(KJ) = JI
14 - 10 = 4
JI = 4
Now we plug in the numbers from our first equation:
JH = JI + 11
JH = 4 + 11
JH = 15
Answer:
JH= 15Step-by-step explanation:
Let KJ= 10, KI= 14, and IH= 11KI - KJ = J14 - 10 = 4J + IH = JH4 + 11 = 15[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]

harold licorice company made 6,429.4 feet of licorice in 9 days. to the nearest hundredth of a foot how many feet of licorice on average did the company make per day
Answer: 714.4
Step-by-step explanation: It says the company had made 6,429.4 feet of licorice in 9 days and you want to find the average amount made in 1 day. So what you would do is divide 6,429.4 by 9 and get 714.3777777 so on. Next its says by the nearest hundredths place meaning the 2nd placement after the dot, so what you would do is round it and you get 714.4.
First of what is the inverse of FX = 2x - 3
Answer: [tex]f^{-1}(x)=\frac{x+3}{2}[/tex]
Step-by-step explanation:
The inverse of an equation is when you switch the x-value with the y-value. The y-value is equal to f(x). So, your work will look something like this. Note the changes in bold.
f(x) = 2x - 3
f(x) = y
y = 2x - 3
x = 2y -3
x + 3 = 2y
[tex]\frac{x+3}{2}[/tex] = y
y = [tex]\frac{x+3}{2}[/tex] (here, I'm just switching it so the y-value is on the left to make it easier to read)
y = f(x)
[tex]f^{-1}[/tex](x) is the notation for inverse f(x)
So, the final equation would be written as
[tex]f^{-1}(x)=\frac{x+3}{2}[/tex]
