kyle regalara 16 figuras y le quedara 3/4 de ellas
Answer:
42 minutes
Explanation:
The total amount of anything expressed in percentage is 100%.
The reason for this is that per cent means per hundred.
So, 100% is

, which is a whole.
Moving to the question, a total of 25% + 5% = 30% of the time is used up by commercials and credits.
The time left for the program is 100% - 30% = 70%.
This is 70% of 60 minutes or

Answer:
The coefficient is 3 and the constant is 4 in
relation to the equation mx + c where m is the coefficient of x and c is the constant.
Answer:
(2x - 1)
Step-by-step explanation:
- <em>Volume of a rectangular prism is: V = lwh, where l= lenght, w= width, h= height</em>
<h3>Given</h3>
- V = 36x³ + 60x² + x - 20
- l = (3x + 4)
- w = (6x + 5)
and
<h3>Solution</h3>
Since the volume is the polynomial of third degree and the two of the factors are of the first degree, the third factor is going to be a first degree as well in the format of (mx +n)
<u>So we have below equation:</u>
- 36x³ + 60x² + x - 20 = (3x + 4)(6x + 5) (mx + n)
<u>We can work out the value of m and n:</u>
- 3x*6x*mx = 36x³
- 18mx³ = 36 x³
- m = 2
<u>And</u>
- 4*5*n = -20
- 20n = -20
- n = -1
So we get the factor of (mx + n) = (2x - 1)
<u>Therefore </u>
<u>Proof of the polynimial is correct:</u>
- (3x + 4)(6x +5)(2x - 1) =
- (18x²+39x+20)(2x - 1) =
- 36x³ - 18x² + 78x² - 39x + 40x - 20 =
- 36x² + 60x² + x - 20
Step-by-step explanation:
81 - 1.2x < 55
81 < 55 + 1.2x (add 1.2x to both sides)
1.2x > 26 (subtract 55 from both sides)
x > 21 2/3.
