Answer 1

Answer:
Part A).
If 100 fish all had the same weight, and they weighed
235 pounds when they were all on the scale at the
same time, then each fish weighed

   235 / 100 pounds .

Part-B).
You can find that actual weight with your calculator.

   235 / 100 = 2.35 pounds .

Part-C).
If there were only 10 fish but their total weight was still 235 pounds,
then each fish would have to weigh a lot more, to make up the same
weight with only 10 of them.

Now, each fish would have to weigh   235 / 10 pounds .

That number is 235/10 = 23.5 pounds.

If there were only 1/10 as many fish, then in order to add up to the
same total weight, each fish would have to be 10 times as heavy.

Rate for 40 meters in 10 seconds?

Answers

The rate for 40 meters in 10 seconds is

40m/10sec (40 meters per 10 seconds)

You can turn it into a different unit of measurement by multiplication or division.

For example, if you want the rate in 1 second, you divide both units by 10 (because there are 10 seconds, and 10 ÷ 10 = 1).

40m/10sec then becomes

4m/1sec (4 meters per 1 second)

40 ÷ 10 = 4, and 10 ÷ 10 = 1

Or if you'd like it in minutes, you multiply both units by 6 (because there are 60 seconds in 1 minute, and 6 x 10 = 60).

40m/10sec becomes

240m/60sec = 240m/1min

40 x 6 = 240, 10 x 6 = 60 = 1 minute

A shopper bought shoes marked $40. The sale tax is 8%. How much did the shopper pay in all?

Answers

so she payed 40 plus 8% of tax, that is:
total = 40 + (8%)(40)
total = 40 + (0.08)(40)
total = 40 + 3.2 = 43.2
that is the total pay

-2x - y = -9
y = -2x + 9

5x-2(-2x + 9) = 18
5x - (-4x +18) = 18
9x -18 = 18
9x = 36
x=4

-2x - y = -9
-2(4) - y = -9
-8 - y = -9
-y = -1
y = 1
