Answer:
6/6
Step-by-step explanation:
1/2 or 0.5 in decimal form
We have an equation: 250/?= 50/100
Cross multiply:
50*?= 250*100
⇒ ?= 250*100/50= 500
The number is 500~
We have another equation: ?/500= 80/100
Cross multiply:
100*?= 80*500
⇒?= 80*500/100= 400
80% of 500 is 400~
Answer:
Increase of 2°F/h..... Option 4.
Step-by-step explanation:
Here in the table time in hours is the independent variable (x) and temperature in °F is the dependent variable (y).
The initial temperature at x = 0 hour is 52°F and then the temperature increases by 2°F per one hour time spent.
Therefore, the temperature is increasing at a constant rate of 2°F per hour from an initial value of 52°F.
Hence, option 4 is correct.
