Answer:
Explanation:
The missing equation is:
You are given:
- Ta = the temperature surrounding the object = 73ºF
- T₀ = the initial temperature of the object = 204ºF
- t = 2.5 min
- T after 2.5 min = 180ºF
Question 1: Find the the value of k.
Substitute the data into the equation and solve for k:
Question 2: Find the Fahrenheit temperature of the cup of water, to the nearest degree, after 4 minutes.
Subsititute into the formula and compute:
$3.15 would be the cost, after the mark up is added.
Answer:
The dimensions of the herb garden on the scale drawing are 2.4 by 6 inches
Step 1 (finding the scale factor):
12/10 (inches/feet) or 1.2 (inches/feet)
(1.2 inches<em> </em>in the <em>drawing</em> represent 1 foot in real life)
Step 2 (finding the dimensions of the herb garden on the scale drawing):
Real life dimensions are 2ft by 5ft so we multiply by the <em>scale factor</em>:
2ft = 2 x 1.2 = 2.4 inches
5ft = 5 x 1.2 = 6 inches
So the dimensions of the herb garden on the scale drawing are 2.4 by 6 inches.
8. You would take 48 (white tiles) then divide it by 6 to get 8. (Grey tiles)
