You are not doing as well as you had hoped in one of your classes. So, you want to
figure out the minimum grade you need on the final exam to receive the semester grade
that you want. Is it still possible to get an A? How would you explain your calculations
to a classmate?
1. The grading scale states that you must have a 90% to earn an A for the semester.
There are five tests cach semester (four exams and one final). Given the percentage
scores on the first four exams, determine if it is possible for you to get an A with
your score on the final. Remember, the maximum possible score is 100%.
a. Exam 1 = 85, Exam 2 = 80, Exam 3 = 94, and Exam 4 = 93
Can you cam an A? If so, what score would you need on the final exam? If
not, what is the highest percent you can get for your semester grade? Explain.
b. Exam I = 82, Exam 2 = 84, Exam 3 = 83, and Exam 4 = 96
Can you cam an A? If so, what score would you need on the final exam? If
not, what is the highest percent you can get for your semester grade? Explain.
2. What is the lowest single score (percent) you could get on one of the five exams
and still receive an A? How did you calculate your score? Explain it to your friend
who believes the only way to receive an A is by carning an A on every exam. Is
she right? Why or why not?

Which equation determines d, the cost in dollars to clean r rooms?
Answer:
[tex]d = 29r + 10[/tex]
Solving steps:
To check :--
=> d = 29r + 10
according to the table lets insert 3 to check if it's correct
=> d = 29r + 10
=> d = 29(3) + 10
=> d = 87 + 10
=> d = 97
so therefore it gave us the correct answer according to the table the cost in dollar where 97 and since it gives us 97 it's correct

Make y the subject in the formula x = 5y – w.
Answer:
y=x+w/5
Step-by-step explanation:
x=5y-w
step 1: bring the additional letters/numbers next to the "5y" over to the left
x+w= 5y
step 2: divide the numbers and letters on both sides of the "=" by 5 to only get the letter y
x+w/5= y
step 3: swap them over
y= x+w/5
(we can't get an answer from x+w/5 because the terms are unlike, therefore we keep it as a fraction

The figure below is made up of a regular polygon surrounded by identical triangles. Find the area of the figure.
Answer:
Total area = 937.75
Step-by-step explanation:
Area of triangles = ((b*h)/2) * 5
= (12*23/2) * 5
= 138 * 5
Area of triangles = 690
Area of pentagon = a² * √(25 + 10√5) / 4
= 12^2 * √(25 + 10√5) / 4
Area of pentagon = 247.75
Total area = Area of triangles + Area of pentagon
Total area = 937.75
There are 300 students in the 6th grade. The ratio of students who play an instrument to all students is 2:5. Hou
many people in 6th grade play an instrument?
Answer:
120 students
Step-by-step explanation:
By setting up the equation 2/5=x/300, we can cross cancel, changing the equation into 5x=600, and by dividing both sides by 5, the 5 in 5x cancels out and 600 divided by 5 is 120.

Jacquie bought 12 pens for her students for $10.56. If she wants to buy another 18 pens, how much will they cost?
Answer:
$15.84
Step-by-step explanation:
We can write a proportion to solve
12 pens 18 pens
------------ = -------------
10.56 cost
Using cross products
12 * cost = 10.56 * 18
12 cost = 190.08
Divide each side by 12
cost = 190.08/12
cost =15.84
Answer:
$15.84Step-by-step explanation:
Writing a proportion.12 pens 18 pens
------------ = -------------
10.56 cost
Cross products
12 * cost = 10.56 * 18
12 cost = 190.08
( ÷ ) each side by 12
cost = 190.08/12
cost = 15.84
#BrainliestBunchA rectangle has vertices (8,6), (4, 6),
(8,-4), and (4,-4). What are the
coordinates after dilating from the origin
by a scale factor of 1.5?
Answer:
the dilated coordinates are (12, 9), (6, 9), (12, -6), (6, -6)
Step-by-step explanation:
The dilation factor multiplies each coordinate value when the center is the origin.
__
(8, 6) ⇒ 1.5(8, 6) = (12, 9)
(4, 6) ⇒ 1.5(4, 6) = (6, 9)
(8, -4) ⇒ 1.5(8, -4) = (12, -6)
(4, -4) ⇒ 1.5(4, -4) = (6, -6)

A librarian records the number of books read by each person in the Summer Reading
Book Club
Find the median number of books.
Answer:
The median is 5.
Step-by-step explanation:
Each dot represents one recorded value. Therefore, we can observe our data set to be [3, 3, 3, 4, 4, 5, 6, 8, 9, 10, 10].
There are 11 terms, so simply find the "middle" term. The term 5 has five values on either side of it; it is in the "middle".
Therefore, 5 is your median!

You estimate that there are 52 marbles in a jar. The actual amount is 88 marbles. Find the percent error. Round to the nearest
tenth of a percent if necessary.
Answer:
We know that there are total 12 marbles are not there because 48-36=12. Now, I take:
12÷48=0.25 or 25%. As a result, the percent error is 25%. Hope it helps!
Step-by-step explanation:
The percentage error is 40.9%.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, the estimated value is 52 and the actual value is 88.
The percent error is given
error% = (|estimated - actual|)/actual × 100 %
error% = (|52 - 88|)/88 × 100 %
error% = 40.9%
Hence, the percentage error is 40.9%.
