Jerome surveyed 643 skateboarders and found that 209 of them preferred wood skateboards to plastic or aluminum skateboards. Based on the number of people surveyed, what is the most reasonable estimation of the percent of skateboarders who preferred wood skateboards?a)10%
b)30%
c)40%
d)50%

Answers

30% , as:
Let the percentage of people preferring wooden skateboards be 'x'.
Therefore, x/100*643=209
x/100=209/643
x=209*100/643
x=20900/643
x=32.50.......
By rounding it off to 30, we get 30% as answer.

The temperature at 6:00 a.m. was ‐3.5°C. From 6:00 to 7:00, the temperature increased 2.5°C. From 7:00 to 8:00, it decreased by 0.25°C, and from 8:00 to 11:00, the temperature dropped 3.25°C. Which expression shows the temperature in °C at 11:00 a.m.?

Answers

The expression that shows the temperature in °C is $-3.5+2.5+(-0.25)+(-3.25)$ .

Step-by-step explanation:

Step 1:

The initial temperature at 6.00 am was $-3.5$ °C.

Step 2:

From 6.00 to 7.00 am, the temperature increased by another 2.5°C, so the temperature at 7.00 am was $(-3.5 + 2.5)$ °C.

Step 3:

From 7.00 to 8.00 a.m, the temperature decreased by another 0.25°C, so the temperature at 8.00 am was $(-3.5+2.5+(-0.25))$ °C.

Step 4:

From 8.00 to 11.00 a.m, the temperature dropped by another 3.25 °C, so the temperature at 11.00 am was $(-3.5+2.5+(-0.25)+-(3.25))$ °C which is represented by the fourth option.
