Answer:
speed = (3/8 mi)/(3/5 h)
Step-by-step explanation:
... speed = distance/time
Fill in the given values:
... speed = (3/8 mi)/(3/5 h)
_____
<em>Comment on units</em>
You can use the units to provide both guidance and assurance. You know speed is generally expressed in <em>miles per hour</em>. If you consider "per" to mean "divided by", this expression of units tells you speed is calculated by dividing miles by hours.
If you leave the units with the numbers, as we have above, they enter into the calculation the same way any variable might. You can do the arithemetic with the numbers, and you can indicate the arithmetic with the units (just as you would with any variables). Here, the result of evaluating the equation would be ...
The fact that the units come out mi/h (the units of speed) provides assurance that you probably did the math correctly.
Your answer will be 560,000 because you convert 10% to a decimal which is .10 and times .10 by 56,000 and you get your answer 560,000

Answer:
243,729,2187
Step-by-step explanation:
It is multiply by 3, so 81*3 and 81*3*3 and 81*3*3*3 which is 243, 729, 2187
Answer:
Yes.
Step-by-step explanation:
If they do then the slope of PQ will equal that of QR.
The slope of PQ = (y2-y1)/(x2-x1)
= (1 - (-3)) / (2-1) = 4.
The slope of QR = (3-1)/(2.5-2)
= 2 / 0.5 = 4.
So they are on the same line.
