Answer:

5cm

Step-by-step explanation:

Given data

Length= 3cm

Width= 4cm

Applying Pythagoras theorem

z^2= x^2+y^2

z^2= 3^2+ 4^2

z^2= 9+16

z^2= 25

square root both sides

z= √25

z= 5cm

Hence the diagonal is  5cm

The temperature outside is currently 10°F. It will fall at a constant rate of 3°F per hour. Which temperature will it be in 4 ho
Triss [41]

Answer:

T4 = -2°F

Step-by-step explanation:

Given the following data;

Current temperature = 10°F

Constant, K = 3°F

Time, t = 4 hours

In four (4) hours, we have;

T = kt

Substituting into the equation, we have;

T = 3 * 4

T = 12°F

T4 = current temp - new temp

T4 = 10°F - 12°F

T4 = -2°F

Therefore, the temperature it will be in 4 hours is - 2°F.
