Answer:
A) 2f / hour
B) 10 f
Step-by-step explanation:
outside temperature decreases by ; 7 F in 3 1/2 hours
a ) represent temperature change as a unit rate
To do this you will need to represent the temperature change per hour
7 f / 3.5 hours
= 7 f / 3.5 = 2 therefore the temperature change as a unit rate = 2f / hour
b) Temperature change after 5 hours
Δ temperature in 5 hours = temperature change per hour * 5
= 2 F * 5 = 10 F

Answer:
Height = 5 and Base = 10
Step-by-step explanation:
The base of the parallelogram is twice the perpendicular height of the parallelogram. The area of the parallelogram is 50 cm².
Formula for area of parallelogram = base × height
Base = 2h
Height = h
∴ Area = 2h × h = 50
Solution:
2h × h = 50
2h² = 50

h² = 25

h = 5
∴ height = 5 and base = 2(5) = 10
Answer: The two correct answers would be 40 and 45.
Step-by-step explanation: The square root of 40 is 6.32 which is between our given values 6 and 7 it also can be represented as 2 sq rt 10 The sq rt of the second number 45 is 6.70 which is again between the 2 values. It can also be represented as 3 sq rt 5. Hope this helps!
