The representation of Matt's reading the book is an illustration of unit rates
The best representation of the rate is (b) Matt reads 66 pages per hour
How to determine the representation?
The given parameters are:
Pages = 792 pages
Time = 12 hours
The rate is then calculated as:
Unit Rate = Pages/Time
This gives
Unit Rate = 792/12
Evaluate the quotient
Unit Rate = 66
This means that Matt reads 66 pages per hour

Juanita has a storage closet at her shop with extra bottles of lotion and shower gel. some are scented and some are unscented. if she reaches into the closet and grabs a bottle without looking, she has a 42% chance of grabbing a bottle of shower gel. for the events "shower gel" and "scented" to be independent, what must be shown to be true? p(lotion) = 42% p(scented) = 42% p(shower gel | scented) = 42% p(scented | shower gel) = 42%
The probability of selecting a shower gel given item is scented must be the same as grabbing shower gel which is 42%.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Juanita has a storage closet at her shop with extra bottles of lotion and shower gel, some are scented and some are unscented.
If she reaches into the closet and grabs a bottle without looking, she has a 42% chance of grabbing a bottle of shower gel.
For the events "shower gel" and "scented" to be independent.
P(A|B) = P(A)
P(B|A) = P(B)
P(A∩B) = P(A) × P(B)
We know that the probability she selects a shower gel is 42%. Let this event be A. Then we have
P(shower | scented) = P(shower gel) = 42%
This must be true for the events to be independent.

Determine the number and type of solutions of the quadratic
equation.
4x2 – 3x + 1 = 0
O one real solution
O two imaginary solutions
O one imaginary solution
O two real solutions
Answer: Choice B
Two imaginary solutions
=======================================================
Explanation:
The given equation is
4x^2 - 3x + 1 = 0
Compare this to the general quadratic
ax^2 + bx + c = 0
to find that a = 4, b = -3, c = 1.
Plug those values into the discriminant formula below.
d = b^2 - 4ac
d = (-3)^2 - 4*4*1
d = 9 - 16
d = -7
Then recall that...
If d > 0, then we have two real solutions.If d = 0, then we have only one real solution.If d < 0, then we have two imaginary solutions.We see that d = -7 fits with the third option highlighted above.

A literary agent makes $30,000 a year plus 13% commission on the sales of her clients' books to publishers. The agent sold 4 books for $175,000 each for her
clients this year.
Find her total earnings.
Answer:
She made $121000.
Step-by-step explanation:
The money the agent sold was:
4*175000=700000 (dollars)
but she only gets 13% of this, so she earned:
700000*0.13=91000 (dollars)
She also makes $30000 per year, so the total income she earned was:
91000+30000=121000

Answer:
Angles 6 & 7 are consecutive interior angles
Step-by-step explanation:
They are both on the same side of the transversal, and on the interior parts of the parallel lines.
7. Angle A and Angle B are congruent. The measure
of Angle A is 2x + 3. The measure of Angle B is 3x –
5. Solve for x. What is the measure of each Angle?
=========================================
Work Shown:
angle A = angle B
2x+3 = 3x-5
3+5 = 3x-2x
8 = x
x = 8
angle A = 2x+3
angle A = 2*8+3
angle A = 16+3
angle A = 19
angle B = 3x-5
angle B = 3*8-5
angle B = 24-5
angle B = 19
Both angles are the same measure (19), which confirms our answer.
Answer:
X=8
Step-by-step explanation:
2x+3=3x-5. subtract 2x from both sides
3=x-5. add 5 to both sides
3+5=x
x=8
Jane made $108 for 9 hours of work.At the same rate, how many hours would she have to work to make $216?
pls help
Answer:
18 hours
Step-by-step explanation:
$108 = 9 hours
$216 = x hours
we want to get to $216 from the original equation. one thing we can do to get there is to figure out what we need to multiply 108 by to get 216. to figure this out, we can calculate 216/108 = 2.
therefore, we can multiply both sides of the original equation by 2 to get
$216 = 9 * 2 hours = 18 hours as our answer

An employee at a clothing store makes $12.75 per hour plus a 5.75% commission on sales. This week she worked 45 hours and her sales were $12,675. How much did she earn this week?
Answer:$1,302.56
Step-by-step explanation:
First you must find the amount she made from working her hours.
$12.75 x 45(hours)=$573.75
Next you must find how much she made from her commission on sales.
$12,675 x 0.0575(5.75% converted to a decimal)=728.8125.
Round 728.8125 to the nearest hundredth to get $728.81.
Add these two numbers together.
$728.81+$573.75=$1,302.56
Answer:
$1,302.56
Step-by-step explanation:
You must first determine how much she earned throughout her working hours.
$12.75 multiplied by 45 hours equals $573.75.
The next step is to determine how much she earned from her sales commission.
728.8125 = $12,675 x 0.0575(5.75 percent converted to a decimal).
To get $728.81, round 728.8125 to the nearest hundredth.
These two integers should be added together.
$728.81+$573.75=$1,302.56

Find the area of the rectangle with the given base and height.
3 ft 3 in
The area of the rectangle is it?
(Type an integer or a simplified fraction.)
Plz help
Answer: Area = 108 in. or 3/4 ft.
Step-by-step explanation: The formula for the area of a rectangle is l•w (length times width).
To get the area, you need to convert the units of measurement to one or the other (either inches or feet) because you cannot multiply them unless they are the same.
To get the area in inches, you convert 3 ft. to inches which is 36 inches, and then multiply it by 3 inches. You will get that the area = 108 inches.
To get the area in feet, you convert 3 inches to feet which is 1/4 (or 0.25) feet and then multiply it by 3 feet which gives you area = 3/4 ft. (or 0.75 ft.). Hope this helps.
Find the equation of the linear function represented by the table below in slope-intercept form.
x y
-4 0
1 5
6 10
11 15
Answer:
the desired equation is y = x + 4.
Step-by-step explanation:
Slope is defined as m = rise over run. Run is the change (usually an increase) in x, and rise an increase or decrease in y.
We see, in the table, that if x increases from 1 to 6 (a 'run' of 5), y increases from 5 to 10 (a 'rise' of 5). Thus, it's immediately apparent that the slope is m = rise / run = 5 / 5, or just 1.
Using the slope-intercept form of the equation of a straight line, y = mx + b, and the point (1, 5), we calculate b:
5 = 1(1) + b, or b = 4.
Therefore the desired equation is y = x + 4.

∠A and ∠B are complementary. The measure of ∠A is 32°. What is the measure of ∠B? Enter your answer in the box. °
Answer:
∠B = 58°
Step-by-step explanation:
∠A and ∠B are complementary.
-> ∠A + ∠B = 90°
-> 32° + ∠B = 90°
-> ∠B = 90° - 32°
-> ∠B = 58°
Answer:
<B = 58
Step-by-step explanation:
complementary angles are angles that sum up to 90°.
If A and B are angle when added will form 90°, to find B we follow the following steps
A + B = 90
if A = 32°,
32 + B = 90
collect like terms
B = 90 - 32
B = 58
that means
32 + 58 = 90
B = 58
