Answer: 9 / 11
That is approximately 0.82
Explanation:
The ratio of two quantities x and y is x divided by y, i.e. the quotient x / y.
So, the ratio of Sylia's work time to Paul's work time is:
Sylvia's work time
---------------------------
Paul's work time
Given that you have the times in mixed units, hours and minutes, you must convert to one of the, either hours or minutes.
If you choose to work with hours, this is the work:
1) Silvia's time: 3 hours and 45 minutes = 3 hours + 45 / 60 hours = 3hours + 0.75 hours = 3.75 hours
2) Paul's work time: 4 hours and 35 minutes = 4 hours + 35/60 hours = 4 hours + 7/12 hours = (48+7)/12 = 55/12 hours ≈ 4.58 hours
3) Ratio:
Sylvia's work time 3.75 hours 3.75*12 45 9
------------------------- = --------------------- = ---------------- = -------- = -----
Paul's work time (55/12) hours 55 55 11
≈ 0.82
You can calculate the ratio using minutes and shall obtain the same result. Look:
1) 3 hours + 45 minutes = 3 * 60 minutes + 45 minutes = 180 minutes + 45 minutes = 225 minutes
2) 4 hours + 35 minutes = 4*60 minutes + 35 minutes = 240 minutes + 35 minutes = 275 minutes
3)
225 minutes 9
----------------- = ------, which is the same result obtained above.
275 minutes 11
Answer:
Need a picture of the problem.
Step-by-step explanation:
Solution:
<u>Given function:</u>
<u>Solution (x = -2):</u>
- f(x) = x - 1
- => -2 - 1
- => -3
<u>Solution (x = 0):</u>
- f(x) = x - 1
- => 0 - 1
- => -1
<u>Solution (x = 2):</u>
<u>Solution (x = 3):</u>
- f(x) = x - 1
- => f(x) = 3 - 1
- => 2
Answer:
41.2
miles
Explanation:
To solve the question, first find the number of miles Rachel power walked.
She walked
2
3
5
or
2.6
miles a day for seven days. Multiply seven days by
2.6
to find the total number of miles Rachel power walked that week.
2.6
⋅
7
=
18.2
Next, find the number of miles Rachel jogged.
She jogged
5.75
miles a day for four days. Multiply
4
by
5.75
to find the number of miles Rachel jogged that week.
5.75
⋅
4
=
23
Rachel power walked 18.2 miles and jogged 23 miles. Add the two values up to find the total number of miles that she power walked and jogged.
18.2
+
23
=
41.2
