Answer:
let 'x' represent the total number of students in the class
5 = 20% of x
0.20x = 5 divide both sides by 0.20
x = 25 students
there are 25 students in the class.
Step-by-step explanation:
Find the value of x in the triangle
Answer:
√41
Step-by-step explanation:
Use a² + b² = c²
a = 4
b = 5
4² + 5² = c²
4² = 16
5² = 25
16 + 25 = c²
41 = c²
You need to get ² away from c, so square root both sides.
√41 = √c²
√41 = c
√41 is in its simplest form, so it is left as √41.

Write an equation of the line below
Answer:
y = 4/5x - 2
Step-by-step explanation:
To create an equation with just a line compare two points on the graph and see how far the x and y points are on the graph then put them into a fraction with y over x then find the y intercept or find where the x coordinate equals 0 in this case it was (0, -2). Now put it all together:
y = mx + b
mx = comparison of two points
b = y intercept

What is the constant of proportionality in the table below?
Answer:
3
Step-by-step explanation:
The constant of proportionality (or the slope) is 3. Observe that if x increases by 2 (from 1 to 3), y increases by 6 from 3 to 9, so that m = rise/run = 6/2, or 3.

Consider the quadratic equation x^2 +7x+8=0. Which of the following is the correct form after substituting a, b, and c into the
Quadratic Formula?
Answer:
ax²+bx+c=0
Being the standard formula
Step-by-step explanation:
By direct substitution
a=1
b=7
c=8
If the quadratic equation x² +7x+8=0 then the correct form after substituting a, b, and c into the Quadratic Formula is x=-7±√7²-4(1)(8)/2(1)
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given quadratic equation is x² +7x+8=0.
The quadratic equation standard form is ax²+bx+c=0
When we compare both the equations
The value of a is 1, b is 7 and c is 8
x=-b±√b²-4ac/2a
x=-7±√7²-4(1)(8)/2(1)
=-7±√49-32/2
x=-7±√17/2
Hence, if the quadratic equation x² +7x+8=0 then the correct form after substituting a, b, and c into the Quadratic Formula is x=-7±√7²-4(1)(8)/2(1)

A shirt originally cost $41.10, but it is on sale for $36.99. What is the percentage decrease of the price of the shirt? If necessary, round to the nearest percent. A. 10% B. 90% C. 11% D. 8%
Answer:
10%
Step-by-step explanation:
The first step is to calculate the decrease
Original price= $41.10
New price= $36.99
= 41.10-36.99
= 4.11
4.11/41.10 × 100
= 0.1×100
= 10%
Hence the percentage decrease is 10%
coterminal angles
HELP what is the coterminal angle for -230° in the range of (0,360°)
Answer:
The coterminal angle of -230º is 130º.
Step-by-step explanation:
Coterminal angles are those whose sides start and end at the same point, therefore sharing a common side. To obtain the coterminal angle of a negative angle, 360º must be added to the value of said negative angle. Therefore, the coterminal angle of -230º arises from the following calculation:
-230 + 360 = X
130 = X
Therefore, the coterminal angle of -230º is 130º.

In circle R with QRS=90 and QR= 3 units find the length of arc QS round to the nearest hundredth
Hello, I Am BrotherEye
Answer:
27.92 units
Step-by-step explanation:
Radius (qr) = r = 16 units
<QŘS = θ = 82°
Length of an arc = (Θ / 360) * 2πr
L = (θ / 360) *2πr
L = (82 / 360) * 2π * 16
L = 0.2777 * 100.53
L = 27.917 units
L = 27.92 unit

What is the MODE of the data - (12, 8, 6, 12, 16, 12) *
help plsssss
Answer: Mode = 12
Explanation: The mode is the most frequent value, so it is the value that shows up the most. In this case, that would be the value "12" since it shows up three times (while the other values only show up once).
Answer:
12
Step-by-step explanation:
For future reference mode means MOST. So in this data, number 12 is repeated the most. That would mean the MODE is 12.
