Given that we have the change in temperature over 7 hours and we are looking for the change over 1 hour, we can divide the total change in temperature by 7. Thus, the change in temperature would be 
.
Additionally, this can be solved by equations:
By using two different methods, we can determine that the change each hour was equal to 42/7 C° per hour.

Answer:
4/15
Step-by-step explanation:
2/3 play sports
2/5 play football
Of the 2/3 that play sports, 2/5 of them play football
2/3(2/5) = 4/15
Answer:
m<ADB=70°
m<ADC=110°
m<DAC=45°
Step-by-step explanation:
<ADB=<ABD(being isosceles triangle: AD=AB)
<ABD+<ADB+<DAB=180°(sum of the angle of triangle is 180°)
2<ADB+40°=180°(<ADB=<ABD and <DAB=40°)
2<ADB=140°
<ADB=70°
<ADB+<ADC=180°(being straight angle)
70°+<ADC=180°
<ADC=110°
<ADC+<ACD+<DAC=180°( sum of the angle of triangle is 180°)
110°+25°+<DAC=180°
<DAC=45°
The answer is b because It’s right
