Answer:
[tex] \frac{7}{72} [/tex]
Step-by-step explanation:
The question is :
[tex] \frac{1}{9} \div \frac{8}{7} [/tex]
We need to take the reciprocal which means invert the :
[tex] \frac{8}{7} [/tex]
So, it will be :
[tex] \frac{1}{9} \times \frac{7}{8} [/tex]
After that , do 1 × 7 on numerator and 9 × 8 on denominator....
After multiplication you'll get :
[tex] \frac{7}{72} [/tex]
1/9 divided by 8/7 is equal to 7/72.
To divide fractions, you can use the following rule: invert the second fraction and multiply it by the first fraction.
In this case, you have:
1/9 ÷ 8/7
To divide, we invert the second fraction:
1/9 × 7/8
Next, multiply the numerators (top numbers) together and the denominators (bottom numbers) together:
(1 × 7) / (9 × 8)
This simplifies to:
7/72
Therefore, 1/9 divided by 8/7 is equal to 7/72.

Answer:
A constant is a defined value often portrayed as a number.
A variable is a value that can change and is often represented as a letter.
Step-by-step explanation:
For example:
In the equation ? = 10x + 3y + 17
10, 3, and 17 are all constants.
X and Y are both variables.

Fit Data to a line
When using empirical data ( data and information collected by scientists in an experiment ), sometimes, that data will not form a perfect line on a graph. when this happens, the line that is created using a linear regression is known as the " line of best fit " the following speed data was collected from a car moving with a constant acceleration.
1 - what is the line of best fit for this data? perform a linear regression on this table to find the equation .
2 - based on your equation, what was the car's approximate initial velocity (at time = 0) ?
3 - if the car continued at the same acceleration (meaning the slope of the line does not change), how fast would it be going in 15 seconds ?
Using a linear regression calculator, the best fit line, initial velocity and the velocity of the car after 15 seconds is :
y = 3.64x + 5.7 Initial Velocity = 5.7 m/s Velocity after 15 seconds = 60.3 m/sUsing technology, the linear regression equation obtained by fitting the data is :
y = 3.64x + 5.7x = times(seconds) ; y = velocity(m/s)The approximate velocity at time = 0 ; x = 0 :
y = 3.64(0) + 5.7
y = 0 + 5.7
y = 5.7 m/s
3.) Velocity after 15 seconds :
At time, x = 15 seconds
y = 3.64(15) + 5.7
y = 60.3 m/s
Therefore, the velocity of the car after 15 seconds is 60.3 m/s

Yael worked out at a gym for 3 hours. Her workout consisted of stretching for 21
minutes, jogging for 39 minutes, and lifting weights for the remaining amount of
time. What percentage of Yael's workout was spent lifting weights?
21 + 39 = 60 minutes ( 1 hour)
So for the remaining time she lifted weights for about 2 hours.
3 hours = 180 minutes
180 - 60 = 120
About 66% of the remaining time Yael used to lift weights.
To be accurate 66.6% ( the last 6 repeating a infinite amount of time aka it doesnt end)
The formula for simple interest is I=Prt,I=Prt, where II is the interest earned, PP is the principal, rr is the interest rate and tt is the number of years. Solve the formula for tt in terms of P,P, II and r.r.
Answer:
t = I/pr
Step-by-step explanation:
I = prt
divide both sides by pr
i/pr = prt/pr , pr cancel out
I/pr = t
t = I/pr

Conduct a simulation using a random number generator based on the following information.
According to a survey by a restaurateur's magazine on favorite types of food, 45% of their
readers chose Italian, 25% Mexican, 15% American, 10% French, and 5% Ethnic.
Any number chosen randomly without any design or process is called a random number.
Italian, = 9/20
Mexican, = 5/20
American, = 3/20
French, = 2/20
and
Ethnic, 1/20
Suppose we choose as the random number then according to the given data
Italian,45% = 45/100 = 9/20
Mexican, 25% =25/100= 1/4× 5/5= 5/20
American, 15% = 15/100= 3/20
French, 10% = 10/100 = 1/10 = 2/20

Aiden makes $22 per hour and Parker makes $26 per hour. Additionally, this week Aiden made a bonus of $100. Given that A and P represent the number of hours worked by Aiden (A) and Parker (P), which expression can be used to represent their combined earnings for the week?
A) 24AP + 100
B) 24 + AP + 100
C) 22A + 26P + 100
D) 22A + 26P(100)
Answer:
It's C
Step-by-step explanation:
So if Aiden earns 22 per hour and Parker 26 per hour too you need to add 22+26 and Aiden had a bonus of $100 so you need to do this 22+26= __ + 100 =
Hope it helps
The expression that can be used to represent their combined earnings for the week is 22A + 26P + 100: Option C is correct
Let the amount that Aiden made per hour be A
Let the amount that Parker made per hour be P
Bonus earned by Aiden this week = $100
If Aiden makes $22 per hour, the total amount made by Aiden = 22A + 100
If Parker makes $26 per hour, the total money made by Parker = 26P
Total earning = total amount made by Aiden + total amount made by Parker
Total earning = 22A + 100 + 26P
Hence the expression that can be used to represent their combined earnings for the week is 22A + 26P + 100

What are Decimal?A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point.
