Ralph spends 15 1/3 hours per month playing tennis. How many hours does he play tennis in a year? (There are twelve months in a year.)a. 182 2/3
b. 164
c. 184
d. 164 1/3

Answers

Number of hours that Ralph spends playing tennis in a month = 15 1/3 hours
      = 46/3 hours
Number of months in a year = 12 months
Then
The total number of hours that Ralph spends playing tennis = (46/3) * 12 hours
      = 46 * 4 hours
   = 184 hours
So from the above deduction we can see that the total time spent by Ralph in playing tennis in a year is 184 hours. So the correct option among all the options given in the question is option "c". I hope the procedure is clear enough for you to understand.

184 hours a year cause 15x12 is 180hours and 20x 12 is 240 minutes and 240 minutes is 4 hours so 180+4 is 184 hours

7. 2.1 + 3.32 – 1.4 = ?

Answers

Hi there! :) The answer to your question is 4.02. I did 2.1+3.32= 5.42 then I did 5.42-1.4= 4.02. That I how I got the answer.

Hope I helped! ;D

4.02, first you add together 2.1 and 3.32, then once you get that answer (5.43); you subtract 1.4. Remember that when adding and subtracting to always go left to right.

Step by step solve this problem -4=r/20-5

Answers

-4 = $(r)/(20)$ - 5
$(r)/(20)$ - 5 = -4 (Switched sides)
( $(r)/(20)$ - 5)20 = (-4)20 (Multiply both sides by 20)
r-100 = -80
r - 100 + 100 = -80 + 100 (Add 100 to each side)
r = 20

Solve the following equations.
ln(x + 1) − ln(2) = 1

Answers

Answer:

The sollution is x = 2e -1

Step-by-step explanation:

Hi there!!

First, let´s write the equation:

ln(x + 1) - ln(2) = 1

Apply logarithm property: ln(x+1) - ln(2) = ln((x+1)/2)

ln((x+1)/2) = 1

Apply e to both sides of the equation

e^[ln((x+1)/2)] = e¹

Apply e^[ln((x+1)/2)] = (x+1)/2

(x + 1) / 2 = e

Multiply by 2 both sides of the equation

x + 1 = 2e

Substract 1 from both sides of the equation

x = 2e - 1

The sollution is x = 2e -1

Have a nice day!
