Answer to the first problem is 3 3/9

Reasoning:

To do these equations, you must change the mixed numbers into just fractions. I will do the first problem :)

2 divided by 3 2/3.

The first step in solving this equation is changing 3 2/3 back into a fraction.

To do this, do the denominator (3) times the whole number (also 3) and then add the numerator (2). 3 x 3 = 9. 9 is now your numerator and 3 is your denominator. 9/3

After this you want to put 10/1 MULTIPLIED by 3/9 (when dividing fractions you must flip the second fraction AND THEN MULTIPLY)

So 10/1 MULTIPLIED by 3/9 = 30/9

It then wants us to simply our answer. To do this, divide 30/9 by 9. You’ll get 3 3/9 as your answer for question 1!

Compound Interest: You deposit $100 in an account that earns 3% annual interest compounded continuously. How long does it take t

Answer:

  a) 3.18 years

  b) 13.52 years

  c) 23.10 years

Step-by-step explanation:

Solving for t, we find ...

  A = Pe^(rt)

  A/P = e^(rt)

  ln(A/P) = rt

  t = ln(A/P)/r

For P=100 and r=.03, the times are ...

a. $110: t = ln(110/100)/.03 ≈ 3.18 years

b. $150: t = ln(150/100)/.03 ≈ 13.52 years

c. $200: t = ln(200/100)/.03 ≈ 23.10 years

Johnny is paid a one-time fee of $245.00 for all his jobs. His uncle also pays him $20.00 for each hour that he works. After all
Free_Kalibri [48]

Answer:

100 hours

Step-by-step explanation:

If Johnny is paid 245.00 as a one time fee for all his jobs then the total money he is paid is 2245.00

We need to separate the hourly fee from the one-time fee so we subtract 245 from 2245. This leaves us with 2000 dollars.

We know that he will be paid 20 dollars per hour so we need to divide 2000 by 20. This leaves us with 100.

<h2>Therefore Johnny worked 100 hours</h2>

What is the equation of the line through (−2, −2) and (4, −5)?
blondinia [14]

Answer:

Step-by-step explanation:

(-5 + 2)/(4 + 2) = -3/6 = -1/2

y + 2 = -1/2(x + 2)

y + 2 = -1/2x - 1

y = -1/2x - 3
