Okay so the formula for this is going to be 1/2*base*height. The * means multiply.
so to do it easily lets start with the whole numbers.
15*9=135
so we take that and divide it by two because that it the same as multiplying by 1/2
135/2=The area will be 67.5!!!
Hope this helps you
Because it was divided three times
If the temperature drops 3 degrees ever hour, and she monitors it for 5 hours, then the equation would be 3 x 5 = 15. So the temperature ultimately has dropped 15 degrees during the past 5 hours.
Answer:
k = 27/4
Step-by-step explanation:
1/5 (k - 3) = 3/4
Multiply both sides by 5 or 5/1:
5 ⋅ 1/5 (k - 3) = 3 ⋅ 5/4
Simplify:
k - 3 = 15/4
Add 3 to both sides:
k - 3 + 3 = 15/4 + 3
Therefore:
k = 27/4
I hope this helps!
