Answer:
-20x.....
Step-by-step explanation:
–4(5x)
-20x
We know that 1 meter is 0.001 km and that 1 minute is 60 seconds.
To transform 15m/s we into km/min we have to multiply 15 by 0.001 and multiply it by 60.

- its the answer
Example 1 – Constructing a frequency distribution table
Divide the results (x) into intervals, and then count the number of results in each interval. ...
Make a table with separate columns for the interval numbers (the number of cars per household), the tallied results, and the frequency of results in each interval.
Answer:
5.59 times per second.
Step-by-step explanation:
Direct variation is in the form:

Where <em>k</em> is the constant of variation.
Inverse variation is in the form:

In the given problem, the frequency of a vibrating guitar string varies inversely as its length. In other words, using <em>f</em> for frequency and <em>l</em> for length:

We can solve for the constant of variation. We know that the frequency <em>f</em> is 4.3 when the length is 0.65 meters long. Thus:

Solve for <em>k: </em>
<em />
<em />
<em />
So, our equation becomes:

Then when the length is 0.5 meters, the frequency will be:

Answer:
A: 124 in
D: 2 yd 52 in
E: 10 ft 4 in
Step-by-step explanation:
we know that
1 ft=12 in
1 yd=36 in
we have
3 yd 16 in
Convert to inches
3 yd 16 in=3(36)+16=124 in
<em>Verify each case</em>
case A) 124 in
124 in=124 in ------> is true
therefore
124 in is equal to 3 yd 16 in
case B) 4 yd 4 in
Convert to inches
4 yd 4 in=4(36)+4=148 in
124 in=148 in ------> is not true
therefore
4 yd 4 in is not equal to 3 yd 16 in
case C) 3 yd 1 1/2 ft
Convert to inches
3 yd 1 1/2 ft=3(36)+1.5(12)=126 in
124 in=126 in ------> is not true
therefore
3 yd 1 1/2 ft is not equal to 3 yd 16 in
case D) 2 yd 52 in
Convert to inches
2 yd 52 in=2(36)+52=124 in
124 in=124 in ------> is true
therefore
2 yd 52 in is equal to 3 yd 16 in
case E) 10 ft 4 in
Convert to inches
10 ft 4 in=10(12)+4=124 in
124 in=124 in ------> is true
therefore
10 ft 4 in in is equal to 3 yd 16 in
