Rachel found that the time it takes for her to make her favorite desert decreases the more times she makes its. The time is takes in minutes(M) can be modeled by: M=72-0.75n, where n is the number of times that rachel has made the desert.
A. how long will it take rachel to make her desert the fifth time?
B. after how many times will rachel be able to make her desert in 63 minutes?
C. How long will it take rachel to make her desert the 40th time? Do you think this is reasonable?
Answers
Answer:
A: 68.25 minutes
B: 12 times
C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.
Step-by-step explanation:
a: 72 -0.75*5 = 68.25
b: M=63=72-0.75n
subtract 72 from each side: -9 = -0.75n
divide each side by -0.75: n = 12
so 12 times
c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.

An angle measures 48.4° less than the measure of its complementary angle. What is the measure of each angle?
Answers
Answer:
The angles are 69.2 degrees and 20.8 degrees
Step-by-step explanation:
Complementary angles, when added together, = 90°
We’ll call the first unknown angle a and the second angle b
b = a - 48.4
a + b = 90
So let’s substitute in for b in the second equation:
a + a - 48.4 = 90
2a - 48.4 = 90
2a = 138.4
a = 69.2
69.2 - 48.4 = 20.8 = b
Now, does a + b = 90?
69.2 + 20.8 = 90

The number of storybooks owned by eight classmates is shown below: 8, 9, 9, 7, 8, 6, 9, 8. The mean is 8 and Absolute Deviation= 0.
How to find the mean value of a data set?The mean value of the data set is the ratio of the sum of the data set's values to number of values it has.
If the data set consists of values
x_1, x_2, ..., x_n
, then we get the mean value as:
[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]
The number of storybooks owned by eight classmates is shown below:
8, 9, 9, 7, 8, 6, 9, 8
Part A:
[tex]\overline{x} = \dfrac{ 8+ 9+ 9+ 7+ 8+ 6+ 9+ 8}{8}[/tex]
Therefore, The mean is 8
Part B: Absolute Deviation= 0
subtract each number by the mean
8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0
(then divide sum by mean) 0 divided by 8 = 8

Jeff had $20. He spent 3/8 of his money on lunch. How much money does jeff have left?
Answers
Answer:
$12.50
Step-by-step explanation:
3/8 x 20/1 = 7.5
20 - 7.5 = 12.50
Jeff has $12.50 left after spending 3/8 of his money on lunch.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Jeff had $20.
Jeff spent 3/8 of his money on lunch.
To find the money he left after spending on lunch we get by subtracting three by eight from one.
1 - 3/8
=8-3/8
= 5/8 of his money left.
To find out how much money Jeff has left, we can multiply the remaining fraction by his initial amount of money:
Intitial amount is 20
The money left is 5/8.
Multiply five by eight with twenty.
Money left = (5/8) × $20
Five divided by eight times of twenty.
=100/8
When hundred is divided by eight we get twelve point five.
= $12.50
Therefore, Jeff has $12.50 left after spending 3/8 of his money on lunch.
