Penelope decides to reduce her math tutoring to half the amount of time she has been tutoring each month. After making this change, what will be her total amount of monthly income?
Answer: $300 per month (assumed)
Step-by-step explanation:
As figures are lacking in this question, I will use assumed figures and you can use it as a reference.
Assume Penelope had been tutoring for 60 hours a month and her hourly rate was $10 originally.
If she reduces this time to half, the amount of hours she begins to tutor is:
= 60 hours / 2
= 30 hours
At a rate of $10 an hour, her monthly income becomes:
= 10 * 30
= $300 per month
An experiment consists of spinning a spinner. Use the results in the table to find the experimental probability of the spinner not landing on red.
Red = 8
Blue = 7
Green = 9
Yellow = 6
A. 3/5
B. 11/15
C. 2/5
D. 4/15
Answer:
Probability(Not red) = 11 / 15
Step-by-step explanation:
Given:
Outcomes;
Red = 8
Blue = 7
Green = 9
Yellow = 6
Find:
Probability(Not red)
Computation:
Probability(Not red) = 1 - Probability(red)
Probability(Not red) = 1 - [Number of red/ Total]
Probability(Not red) = 1 - [8/(8+7+9+6)]
Probability(Not red) = 1 - [8/30]
Probability(Not red) = 1 - [4/15]
By taking LCM
Probability(Not red) = (15 - 4) / 15
Probability(Not red) = 11 / 15
Last month you purchased 6 individual songs and 1 albums for a total of $21.99.
This month you spent a total of $44.97 on 4 individual songs and 3 albums.
How much does each song and album cost
Answer:
Song =$1.50 Album =$12.99
Step-by-step explanation:
Lets assume Individual songs = x
albums=y
6x + y = 21.99-------- y= 21.99- 6x
4x + 3y= 44.97
Replace y in the second equation
4x+ 3(21.99-6x) = 44.97
4x +65.97- 18x = 44.97
14x= 21
x = 1.50
y= 21.99- (6*1.50)
= 12.99
Which function is best represented by this graph?
A y = 1/4 x + 8
B y = 1/4 x - 2
C y = 4x -2
D y = 4x + 8
⚠️Hurry⚠️
Answer:
B- y=[tex]\frac{1}{4}[/tex]x-2
Step-by-step explanation:
To look at the slope you can count over four and then up one and its at the next point.
Also, the place on the y-axis is at -2
So, b makes the most since :)
Hope this helps :) (if it does, brainliest??)

An Attorney charges a fixed fee on $250 for an initial meeting and $150 per hour for all hours worked after that. Write an equation in slope-intercept form
Answer:
y = 150x + 250
Write an equation in slope-intercept form for the line that passes through the
given point and is parallel to the graph of the given equation.
(-1, -2), 3x - y = 5
Answer:
y = 3x + 1
Step-by-step explanation:
the slope of the line of the given equation can bé find in this way: -a/b, where a is the number that multiplies x and b is the number that multiplies y
m = -3/-1 = 3
two parallel lines have the same slope, so also the line that we are a searching has m=3
now we can use this formula
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point
y-(-2) = 3 (x-(-1)
y+2 = 3x + 3
y = 3x + 3-2
y = 3x + 1

verify X + y equal to y + X when:x=-8/9and y=-3/5
Given:
[tex]x=-\dfrac{8}{9},\ y=-\dfrac{3}{5}[/tex]
To verify:
[tex]x+y=y+x[/tex]
Solution:
We need to verify,
[tex]x+y=y+x[/tex]
Taking left hand side, we get
[tex]LHS=x+y[/tex]
After substituting the values, we get
[tex]LHS=-\dfrac{8}{9}+\left(-\dfrac{3}{5}\right)[/tex]
[tex]LHS=-\dfrac{8}{9}-\dfrac{3}{5}[/tex]
[tex]LHS=\dfrac{-40-27}{45}[/tex]
[tex]LHS=\dfrac{-67}{45}[/tex]
Now,
Taking right hand side, we get
[tex]RHS=y+x[/tex]
After substituting the values, we get
[tex]RHS=-\dfrac{3}{5}+\left(-\dfrac{8}{9}\right)[/tex]
[tex]RHS=-\dfrac{3}{5}-\dfrac{8}{9}[/tex]
[tex]RHS=\dfrac{-27-40}{45}[/tex]
[tex]RHS=\dfrac{-67}{45}[/tex]
Clearly,
[tex]LHS=RHS[/tex]
Hence verified.

What is the value of the expression below when w=3?
10w2 +9w-2
Answer:
85 if the "2" in 10w(2) is being multiplied.
But if not, then
115 if the "2" in 10w2 is an exponent.
Answer:
85
Step-by-step explanation:
10(3)2 + 9(3)-2
(30)2 + (27)-2
60+25=85

Answer:
D. PerpendicularStep-by-step explanation:
First answer A. Answer A is not even correct. Parallel are two or more lines that NEVER cross
Answer B is also not correct. Line segments are a line of specific length. These are two LINES. You can tell by the arrows on the edge of each line.
Both C and D can be correct. But the answer would be D. Here is why
Intersecting lines are two or more lines that cross. Yes these lines are crossing by perpendicular lines also cross. The difference is, intersecting lines can cross at any angle. Perpendicular lines have to cross at 90 degrees making 4 right corners.

Suppose that the population of deer in a state is 7,700 and is growing 3% cach year. Predict the population
after 5 years
Answer:
Future Value= 8,927
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 7,700
Growth rate (g)= 3%
Number of periods (n)= 5 years
To calculate the future value (FV) of the population after 5 years, we need to use the following formula:
FV= PV*(1 + g)^n
FV= 7,700*(1.03^5)
FV= 8,927
Determine x-intercepts and zeros of each function
Given:
The function is:
[tex]y=-(2x-4)(x-2)[/tex]
To find:
The x-intercepts and zeros of the given function.
Solution:
We have,
[tex]y=-(2x-4)(x-2)[/tex]
For x-intercepts, [tex]y=0[/tex].
[tex]-(2x-4)(x-2)=0[/tex]
[tex](2x-4)(x-2)=0[/tex]
Using zero product property, we get
[tex](2x-4)=0[/tex] and [tex](x-2)=0[/tex]
[tex]2x=4[/tex] and [tex]x=2[/tex]
[tex]x=\dfrac{4}{2}[/tex] and [tex]x=2[/tex]
[tex]x=2[/tex] and [tex]x=2[/tex]
The given function has two equal zeroes or x-intercept, i.e., [tex]x=2[/tex].
Therefore, the zeroes are 2 and 2.
Note: All options are incorrect.
