Answer:
23
Step-by-step explanation:
Use the part/whole = %/100.
You have that whole = 115 and % = 20, so that would be:
[tex]part/115=20/100[/tex]
simplify & solve:
[tex]part/115=1/5[/tex]
multiply both sides by 115
[tex]part=115/5\\part = 23[/tex]

Which equation could be solved using this application of the quadratic formula? x = (- 3 plus/minus sqrt(3 ^ 2 - 4(1) * (24)))/(2(1)) A. x ^ 2 + 6x + 24 = 3x B 3x ^ 2 + 3x + 24 = 3 C. x ^ 2 + 3x - 24 = 3 D x ^ 2 + 3x + 24 = 3
Answers
Answer:
[tex]x^2 + 3x + 24 = 0[/tex]
Step-by-step explanation:
Given
[tex]x = \frac{-3\±\sqrt{3^2 - 4*1*24}}{2*1}[/tex]
Required
Select equation with the above solution
The solution is represented as:
[tex]x = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
By comparison:
[tex]b= 3[/tex] [tex]a = 1[/tex] [tex]c = 24[/tex]
So, the equation is:
[tex]ax^2 + bx + c = 0[/tex]

What is the volume, in cubic centimeters, of a cube with an edge length of 15
centimeters?
Answers
Answer:
3375
Step-by-step explanation:
The formula for volume is
volume = length x height x width
or in simpler terms (only works for cubes i think)
v = a^3
so we know that the side is 15cm long, so we substitute that back into the equation, so,
3375 = 15 x 15 x 15
or
3375 = 15^3
I hope that this helps you out :)

If using the method of completing the square to solve the quadratic equation
x? + 15x + 25 = 0, which number would have to be added to "complete the
square"?
Answers
Answer:
31.25
Step-by-step explanation:
The general form of a complete square would be (x + a)^2 + b
Given an equation of X^2 + 15X + 25 = 0,
the idea is to reduce it into the form if (X + C)^2
which can be expanded into X^2 + 2XC + C^2
In this case 15 will be our 2C So our c will be 7.5.
Substituting in these numbers,
We have X^2 + 15X + (7.5)^2 = 0
However our original equation has 25 for its C^2, thus
we need to add 31.25 in order to get (7.5)^2
FYI
The final completed form will be (X + 7.5)^2 - 31.25

Answers
B) $62.40
hope this helps!!
Answer:
a) $10.4
b) $62.4
Step-by-step explanation:
a) What is the amount of markup? $
$52 - 100%
$X - 120%
100X = 52*120
100X = 6240
X = 6240/100
X = $62.4
62.4-52=
$10.4
b) What is the price of the shoes after markup? $
$62.4

HELP PLS
Answers
Answer:
In order to solve this problem, you have to find the lowest common denominator. Take multiples of both 6 and 4 and see which is the lowest you have in common.
4: 4, 8, 12, 16, 20
6: 6, 12, 18, 24
So 12 is the lowest common multiple....
5/6 x ?/? = ?/12 (you have to multiply the numerator and the denominator by the same number)
3/4 x ?/? = ?/12 (you have to multiply the numerator and the denominator by the same number)
When the denominators are the same, you can subtract the numerators. The denominator will stay 12!
