Answer:
2494.756kg
*see below regarding significant digits
Step-by-step explanation:
Set up a grid to help you to know whether to divide or multiply. Stack equivalent values one on top of the other in your grid. Arrange them so that the units will cancel out. This helps you to change the units. See image.
*if you are also learning about "significant digits" then you will have to alter the answer to only include the same number of significant digits as in the question.
The exact calculated answer is 2494.756, but there are only two significant digits in the question, so the answer maybe 2500kg instead. If your teacher hasn't taught sig figs then go with the exact answer.
2494.756kg

Step-by-step explanation:
Answer:
90 yards per minute
Step-by-step explanation:
Armen's time getting back was 36 -8 = 28 minutes. Then the ratio of times is 28/36 = 7/9.
The ratio of speeds is the inverse of this, so his speed coming back is ...
speed/70 = 9/7
Multiplying by 70 gives ...
speed = 70·9/7 = 90 . . . . yards per minute
There was a decrease of 20% in membership from October to November.
Step-by-step explanation:
Step 1; To find the percent by which the running clubs membership decreased we must find the difference between the number of members in October and the number of members in November. The number of members in the club in October was 25 whereas it reduced to 20 in the month of November.
Difference in members = Number of members in October -Number of members in November = 25 - 20 = 5
Step 2; To find the percent decrease in number of members in the running club, we divide the difference in number of members by the number of members in November . We multiply this value by 100 to get it in terms of percentage.
Percent decrease in number of members =(Difference in members / number of members in November) *100
= (5/25) * 100 = 0.20 * 100 = 20%
So number of members in the club decreased by 20% from October to November.
