Answer:
We conclude that it took 5 hours and 20 minutes for the freezer to reach that temperature.
Step-by-step explanation:
We know that the temperature of the freezer is never greater than -2°C. Yesterday the temperature was -10°C but it increased at a steady rate of 1.5°C per hour. We calculate how long in hours and minutes did the temperature increase inside the freezer.
We conclude that the difference in temperature is 8°C.
We get:
We conclude that it took 5 hours and 20 minutes for the freezer to reach that temperature.
Answer:
108 m
Step-by-step explanation:
If the shadow is 0.8 m but actual parking meter is 1.2 m it means the shadow shrinks original by a factor of similarly, if the shadow for the building is 72 m it means it has already been shrunk by a factor of and to get the actual height of the building then we can say that the height be A
Therefore, the actual building is 108 m
2.25 + 8.50x = 50
8.50x = 50 - 2.25
8.50x = 47.75

8.50. 8.50
x = 5.6 hours

First, find the perimeter of the circle
p = 2 × π × r
p = 2 × 3,14 × 19
p = 119.32
The perimeter of the circle is 119.32 cm
Second, find the central angle
Comparison of the central angle, full rotation angle, the arc, and the perimeter can be written as
angle/(full rotation angle) = arc/perimeter
angle = arc/perimeter × (full rotation angle)
Input the numbers
angle = arc/perimeter × (full rotation angle)
angle = 6/119.32 × 360°
angle = 6(360°)/119.32
angle = 2,160/119.32
angle = 18.1
The central angle would be 18.1°
5 x 0.4 = 2 and
= 1.4142....... which is an irrational number
