Answer:

$25.25

Step-by-step explanation:

All you have to do is divide 378.75 by 15 and you get your answer, because we want to make 15 hours turn to 1 so divide both numbers by 15 to get 25.25

What is the greatest common factor of 65 and 91
Sedbober [7]
So,

First, we find the prime factored form (P.F.F.) of 65 and 91.

P.F.F. of 65: 5 * 13

P.F.F. of 91: 7 * 13

Find the common numbers
13

13 = G.C.F.

Note: This method works for finding any G.C.F. (find common primes)

Answer:

  1. y= -12
  2. x = 7
  3. q = -1
  4. x = 24

Step-by-step explanation:

1. ..............................................

  • 6(y + 7) = 2(y - 3)
  • 6y + 42 = 2y - 6
  • 6y - 2y = -6 - 42
  • 4y = -48
  • y = -12

2...............................................

  • 3x + 2(x - 5) = 25
  • 3x + 2x - 10 = 25
  • 5x = 25 + 10
  • 5x = 35
  • x = 7

3 . ..............................................

  • 10q + 3q + 5 = 2(q - 3)
  • 13q + 5 = 2q - 6
  • 13q - 2q = -6 - 5
  • 11q = -11
  • q = -1

4. ..............................................

  • 1/3(x + 6) = 2/3(x - 9)
  • 3*1/3(x+6) = 3*2/3(x - 9)
  • x + 6 = 2(x - 9)
  • x + 6 = 2x - 18
  • 2x - x = 6 + 18
  • x = 24

Is 10/18 and 45/18 proportional
ValentinkaMS [17]

Answer:

No

Step-by-step explanation:

10/18 does not equal 45/18

An example of a proportional number is:

4/5 and 8/10

Both numbers are multiplied by 2 making them proportional

10/18 and 45/18 are not proportional

Hope this helped :)

What is the domain of the step function f(x) = [2x] – 1?
omeli [17]

You have troubles with domains only if you have:

  • Denominators
  • Roots with an even degree
  • Logarithms

In this case, you have neither of these three, so you can compute your function wherever you want. The domain is all real numbers.

How long would it take to double your principal in an account that pays 6.5% annual interest compounded continuously? round your
prisoha [69]
It would take 10.7 years.

The formula for continuously compounded interest is:
A=Pe^{rt}
where P is the principal, r is the interest rate as a decimal number, and t is the number of years.

Using our information we have:
A=Pe^{0.065t}

We want to know when it will double the principal; therefore we substitute 2P for A and solve for t:
2P=Pe^{0.065t}

Divide both sides by P:
\frac{2P}{P}=\frac{Pe^{0.065t}}{P}&#10;\\&#10;\\2=e^{0.065t}

Take the natural log, ln, of each side to "undo" e:
\ln{2}=\ln{e^{0.065t}}&#10;\\&#10;\\0.6931471806=0.065t

Divide both sides by 0.065:
\frac{0.6931471806}{0.065}=\frac{0.065t}{0.065}&#10;\\&#10;\\10.7\approx t
