3. 96 students are enrolled in the Dance Program at Castillero. Of those students, 54 are eighth-graders. The remaining students are 6th or 7th graders. What percentage of the students are not eighth graders?
Answer:
1) new price of the clock is $14.4
2) Kyra scored 70% marks
3) 43.75% students are not eighth graders
Step-by-step explanation:
1. A store manager marked up the price of a $12 clock by 20%. What is the new price of the clock?
Price of Clock = $12
Mark up = 20%
We need to find new price of clock.
The price of clock can be found by finding 20% of 12 and then adding that amount in original price.
So, finding 20% of 12
[tex]20\% of 12 \\=\frac{20}{100}\times 12\\=2.4[/tex]
So 20% of 12 is 2.4
Now finding new price:
New Price = Actual Price + Mark up
New Price = 12 + 2.4
New Price = 14.4
So, new price of the clock is $14.4
2. On a math quiz, Kyra answered 7 of 10 questions correctly. Express her quiz score as a percent.
Total questions = 10
Correct answers = 7
We need to express her quiz score as percent
It can be found using formula: [tex]Percent Score = \frac{Obtained\:Marks}{Total\:Marks}\times 100\%\\[/tex]
Putting values and finding percentage
[tex]Percentage = \frac{Obtained\:Marks}{Total\:Marks}\times 100\%\\\\Percentage = \frac{7}{10}\times 100\%\\Percentage = 70\%[/tex]
So, Kyra scored 70% marks
3. 96 students are enrolled in the Dance Program at Castillero. Of those students, 54 are eighth-graders. The remaining students are 6th or 7th graders. What percentage of the students are not eighth graders?
Total Students = 96
Number of eighth-graders students = 54
Remaining students = 96 - 54 = 42
So, 42 students are 6th or 7th graders
We need to find percentage of the students are not eighth graders.
[tex]\frac{42}{96}\times 100\%\\=43.75\%[/tex]
So, 43.75% students are not eighth graders
What is the difference between plotting (2, 3) and (3, 2) on a coordinate plane? Explain
Answer:
When plotting coordinates, the first variety is referred to as your X axis, whilst the second number is your Y. Since the X axis goes left and right, and the Y axis goes up and down, plotting (2,3) would be a factor nearer to the backside of the plan and someplace in the right. (3,2) would be higher up and less far right.

today reza ate 20 grapes which is 400% as many grapes as he ate yesterday. explain how to use equal ratios to find the number of grapes reza ate yesterday
Answer:
Write 400% as the ratio 400/100. To find an equivalent ratio, you know that 400 divided by 20 is 20, so 100 divided by 20 will give you the answer. 100 ÷ 20 = 5. Reza ate 5 grapes yesterday.
Brainliest please!
Answer:
What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.
To do it, let:
x: number of grapes that Reza ate yesterday
(x / 20) = (100/400).
Clearing x we have:
x = (100/400) * (20) = 5
answer
the number of grapes Reza ate yesterday was 5

Find the area of a square with.
sides 1 2/3
Answer:
25/9 square units OR 25/9 units^2
Step-by-step explanation:
Use the formula A=s^2 where A is the area of the square and s is one side length of a square. Since s=1 2/3=5/3, then (5/3)^2=25/9. So the area of the square is 25/9 units^2.

An engineer designs a 65-foot cellular telephone tower. Find the angle of elevation to the top of the tower at a point on level ground 40 feet from its base. (Round your answer to one decimal place.)
Answer:
the angle of elevation is 58.4°
Step-by-step explanation:
Given the data in the question and as illustrated in the image below;
let ∅ be the angle of elevation;
Opposite (AC) = 65 ft
Adjacent (CB) = 40 ft
we know that; from SOH CAH TOA
TOA
tan∅ = Opposite / Adjacent
so;
tan∅ = 65 / 40
tan∅ = 1.625
∅ = tan⁻¹ ( 1.625 )
∅ = 58.3924 ≈ 58.4°
Therefore, the angle of elevation is 58.4°

d) O Undefined
e)
-24
f) None of the above.
Question 7
9514 1404 393
Answer:
(c) 0
Step-by-step explanation:
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
Filling in the given point values, you have ...
m = (-1 -(-1))/(-3 -10) = 0/-13 = 0
The slope of the line is zero.
__
It is a horizontal line: y = -1.
Answer:
slope = 0
Step-by-step explanation:
The two points have the same y-coordinate, so the points are horizontally aligned.
A horizontal line has slope = 0
