Step-by-step explanation:
Answer:
The current temperature on the X scale is 1150 °X.
Step-by-step explanation:
Let is determine first the ratio of change in X linear temperature scale to change in Y linear temperature scale:



The difference between current temperature in Y linear scale with respect to freezing point is:


The change in X linear scale is:



Lastly, the current temperature on the X scale is:


The current temperature on the X scale is 1150 °X.
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40
Final answer: D
Answer: about 1 cm
Step-by-step explanation:
50 minutes= 5/6 hr
(1 3/4 miles)/ (5/6 hr)= 2.1 miles/hr
