Identify extra or missing information. Solve if possible. Jenna makes $8 an hour babysitting. She works 3 days per week. What is the total amount she makes in a week?
Answer:
The missing information is: how many hours does she works per day?
Step-by-step explanation:
Amount Jenna makes per hour babysitting = $8
Number of days she works per week = 3 days
The missing information is: how many hours does she works per day ?
ASSUME she works 24 hours per day for 3 days
Total amount Jenna earns in a week = $8 × 24 hours × 3 days
= 8 × 24 × 3
= $576

Find the percent of change:
From 64 feet to 48 feet
Answer:16
Step-by-step explanation:
Using this tool you can find the percent Decrease for any value. So, we think you reached us looking for answers to questions like:
1) What is the percentage Decrease from 64 to 48? 2) What is the absolute Decrease from 64 to 48. Or may be: What is the percent change from 64 to 48?
See the solution to these problems just after below.
How to calculate percent change - Step by Step
Percent increase or decrease measures percent changes between two values. Use this calculator when comparing an old value to a new value.
The Percent Calculator (Change) uses this formula:
% change = New Value - Old Value|Old Value|× 100%
Where |Old Value| represents the absolute value of the reference (this is made in order to work well with both positive and negative values of Old Value and New Value. Note that percent change and relative change mean the same thing. It can be a percent increase or a percent decrease depending on the new and the old values. If the new value is greater than the old value, the result will be positive and we will have a increase. On the other hand, if the new value is smaller than old value, the result will be negative and we will have a we have a decrease. The old value, as a reference, may be: a theoretical, the actual, the correct, an accepted, an optimal, the starting, and so on. See more about percent percent change here.
Here are the solutions to the questions stated above:
1) What is the percentage decrease from 64 to 48?
Use the above formula to find the percent change. So, replacing the given values, we have
Percent change = 48 - 6464 x 100 = -25 % (decrease)
Where: 64 is the old value and 48 is the new value. In this case we have a % of decrease because the new value is smaller than the old value.
2) What is the absolute Decrease from 64 to 48?
This problem is not about percent or relative change, but about absolute change. Its solution is very simple:
Absolute change, or
change = new value - old value
= 48 - 64 = -16 (decrease)
Answer: -25%
Step-by-step explanation:A change from 64 to 48 represents a negative change (decrease) of -25%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old
|Old|
x 100%
Percent change = 48 - 64
|64|
x 100 = -16
64
x 100 = -25 % (decrease)
Where: 64 is the old value and 48 is the new value. In this case we have a negative change (decrease) of -25 percent because the new value is smaller than the old value.
9.45% of the rooms in a hotel are booked. If 36 rooms are booked, how many rooms are in the hotel total?

determine the equation of the line that passes through points (-4,5) and has a slope of m = -3
Answer:
y=-3x-7
Step-by-step explanation:
You want to find the equation for a line that passes through the point (-4,5) and has a slope of -3.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was -3. So you can right away fill in the equation for a line somewhat to read:
y=-3x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,5). When x of the line is -4, y of the line must be 5.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the -3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,5).
So, why not plug in for x the number -4 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,5). y=mx+b or 5=-3 × -4+b, or solving for b: b=5-(-3)(-4). b=-7.
Michael is riding his tricycle, he has a head start of 5 meters and is pedaling at 2 meters every 3 seconds. What is the equation of the line? What is the independent and dependent variables?
Answer:
The correct answer is
y = 2 ÷ 3x + 5
where,
x = independent variable
y = dependent variable
Step-by-step explanation:
According to the given scenario, the equation of the line, independent and the dependent variable is as follows:
y = mx + b
Since the head is started with 5 meters and the pedaling at 2 meters for every 3 seconds i.e. 2 ÷ 3
So the equation line is
y = 2 ÷ 3x + 5
where,
x = independent variable
y = dependent variable

1. What is the value of s?
A. 8
B.16
C.16|2
D.32
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex] \cos(30°) = \frac{16 \sqrt{3} }{s} \\ [/tex]
[tex] \frac{ \sqrt{3} }{2} = \frac{16 \sqrt{3} }{s} \\ [/tex]
Inverse both sides
[tex] \frac{2}{ \sqrt{3} } = \frac{s}{16 \sqrt{3} } \\ [/tex]
[tex] \frac{s}{16 \sqrt{3} } = \frac{2}{ \sqrt{3} } \\ [/tex]
Multiply sides by 16√3
[tex]16 \sqrt{3} \times \frac{s}{16 \sqrt{3} } = 16 \sqrt{3} \times \frac{2}{ \sqrt{3} } \\ [/tex]
[tex]s = \frac{2 \times 16 \times \sqrt{3} }{ \sqrt{3} } \\ [/tex]
[tex]s = 32[/tex]
Thus the correct answer is Option D .

1.) Solve the system of equations by method of elimination. Show all your work.
2x + 4y = 8
10x – 4y = 16
Answer:
x=2, y=1
Step-by-step explanation:
Add:
2x+4y=8
+10x-4y=16
------------------
12x=24
Divide by 12 on both sides:
x=2
Substitute x with 2 on either 2x+4y=8 or 10x-4y=16 it doesn't matter it will result in the same answer.
(I will do both of them to prove it but you only need to replace x with one of the equation)
For 2x+4y=8
2(2)+4y=8
4+4y=8
Subtract 4 on both sides
-4+4+4y=8-4
4y=4
Divide 4 on both sides:
y=1
For 10x-4y=16
10(2)-4y=16
20-4y=16
-20+20-4y=16-20
-4y=-4
Divide -4 on both sides:
y=1
The answer for both 2x + 4y = 8 and 10x – 4y = 16 are the same showing that it doesn't matter which equation you replace the number with it will still result you in the same answer
