15. The temperature C, in degrees, that is equivalent to a temperature of F degrees Fahrenheit is given by graph of this equatio
7nadin3 [17]

Answer:

A. How can the equation be used in temperature conversion?

You take the conversion equation C = (5/9) (F - 32) and you replace the F by the value of Fahrenheit degrees...  then solve the calculations to get the degrees in Celsius.

For example, if you have 80°F to convert in °C:

C = (5/9) (80 - 32) = (5/9) (48) = 26.66 °C

B. How can you use the graph to find the body temp in C?

Using the graph will give a very imprecise measure due the scale of the graph.

But you would have to find 98.6 on the axis of X (it represents the °F), then go upwards until you find the line....

Then report that position on the line on the Y-axis (representing the °C) to get your measure.

liubo4ka [24]

Answer:

243 people did not vote

Step-by-step explanation:

First you would calculate the number of people who DID vote:

27% + 43% = 70% (this is how many people voted)

you would then subtract to find the percent of people who DIDNT vote:

100% - 70% = 30%

Finally you would convert the % into an actual number.

0.30 (or 30%) x 810 members = 243 members

So, 243 members didn't vote.

Hope this helps!
