F = 1.8C + 32

С = -10   ⇒   F = 1.8·(-10) + 32 = 14   ⇒   (-10, 14)
С = 0      ⇒   F = 1.8·(0) + 32 = 32      ⇒   (0, 32)
С = 10    ⇒   F = 1.8·(10) + 32 = 50    ⇒   (10, 50)
С = 20    ⇒   F = 1.8·(20) + 32 = 68    ⇒   (20, 68)

I lb = 453.592 g. What is the mass in kg of a an elephant weighing 5,500 lbs?
melamori03 [73]

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

From home to school, Armen spent 36 minutes walking at a speed of 70 yards per minute. What was his speed, if he spent 8 minutes
hram777 [196]

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 were 20 members in thr running club in september. the membership increased to 25 in october. the membership decreased back
OLga [1]

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.
