At Paulson Middle School, 75% of the sixth grade class is making a B or higher. If there are 21 students
making a B or higher, then how many students are in the class?
Answer:
28 students
Step-by-step explanation:
x = Number of students
21 students = 75 percent of x = 3/4 x
3/4 x = 21
x = 21 * (4/3) = 7*4 = 28

how can you get 2 1/2÷5/8
Answer: 4
Step-by-step explanation:
Change the 2.5 to an improper fraction, then multiply by the reciprocal of 5/8.
[tex]2\frac{1}{2} /\frac{5}{8} =\frac{5}{2}*\frac{8}{5}=\frac{40}{10} =4[/tex]
Conversion a mixed number 2 1/
2
to a improper fraction: 2 1/2 = 2 1/
2
= 2 · 2 + 1/
2
= 4 + 1/
2
= 5/

To find new numerator:
a) Multiply the whole number 2 by the denominator 2. Whole number 2 equally 2 * 2/
2
= 4/
2
b) Add the answer from previous step 4 to the numerator 1. New numerator is 4 + 1 = 5
c) Write a previous answer (new numerator 5) over the denominator 2.
Two and one half is five halfs
Divide: 5/

· 8/
5
= 5 · 8/
2 · 5
= 40/
10
= 10 · 4/
10 · 1
= 4
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 5/
8
is 8/
5
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 10 gives 4/
1
.
In words - five halfs divided by five eighths = four.
Bill bought a table on sale for $630. This price was 72% of the original price.
What was the original price?
Answer:
The original price was $875.
Step-by-step explanation:
a = p * w
630 = 72% * w
630 / 0.72 = $875
$875 should be the original price, I hope this helps!

A flower garden is circular. The diameter of the garden is 20 feet. Which is the closest to the total area of the garden?
Answer:
40
Step-by-step explanation:
The total area of the garden is 31.75 sq meters
The first step is to calculate the radius if the circle
The diameter of the garden is 20 feet
2π × radius= 20
2π × 3.14= 20
6.28π= 20
π= 20/6.28
π= 3.18
The area of the flower garden can be calculated as follows
= π × radius²
= 3.14 × 3.18²
= 3.14 × 10.1124
= 31.75 sq meters
Hence the total area of the garden is 31.75 sq meters

How many solutions are shown by the graph of the quadratic function? A zero B one C two D three
A solution to a quadratic is the same as the root or x intercept (when talking about real numbers). The graph shows that we have exactly one x intercept, which is where the parabola touches the x axis. So we have one root.
in the interval 0° ≤ x ≤360°, find the values of x for which tan x =1.3562 Give your answers to the nearest degree
Answer:
The answers are 54 degrees and 234 degrees
Step-by-step explanation:
mathematically we have the tan positive on only two axes
these are the first (0-90) degrees and the 3rd quadrant (180-270)
We start by find the arc tan of the angle value
Thus;
x = arc tan (1.3562)
x = 54 degrees
On the third quadrant, we have it that;
180 + 54 = 234 degrees

Find the slope of the line that passes through the two points.
(10.1) and (7,7)
Answer:
m = -2
Step-by-step explanation:
I believe that you meant (10, 1) and (7, 7) because otherwise I wouldn't be able to answer it.
So y2-y1/x2-x1 is your equation
First plug in the numbers
7-1/7-10
6/-3
-2
Therefore, m = -2
what is the slope help pls?
Answer:
y=7x-6
Step-by-step explanation:
You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say
y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.
