This is an exercise on Thermometric scales.
We have as data:
- T = 220 °C
- T = °F ??
We apply the following formula:
We substitute data in the formula:
First multiply 9 x 220, then the result of this division is divided by 5.
Therefore the cake recipe that should be baked at 220 °C for 45 minutes, on the Fahrenteir scale is 428 °F. Which indicates that it will be very hot.
Answer:
12.
-1.9 , -1.8, -1.7
13.
Points in Quadrant IV have a positive x, and a negative y.
14.
The point (2,9) is reflected over the y-axis, which means the number in x has it's sign flipped.
(-2 , 9) is your answer
15.
In between -7 & -4 is <em>-6, -5</em>
b. -6 is your answer.
16.
Remember that Quadrant II has a negative x, and a positive y. This means that b. (-2, 5) is your answer.
17.
You are reflecting over the y-axis, so you are changing the sign of the x value.
(-3, 5) reflected over the y-axis is a. (3 , 5)
