the formula for the area of a triangle is 1/2 (base x height) so 1/2 of 20 is 10 ,you do 10 times 12 which is 120. So the area is 120 sq cm.
Answer:
16.5 hours
Step-by-step explanation:
You know the initial value (100) and the growth factor (2), along with the period associated with that growth factor (12 hours). This lets you write the exponential growth equation as ...
n = 100×2^(t/12)
For n=260, we can divide by 100 and take the log.
260 = 100×2^(t/12)
2.6 = 2^(t/12)
log(2.6) = (t/12)log(2) . . . . next, divide by the coefficient of t
12×log(2.6)/log(2) = t ≈ 16.5 . . . . hours
It will be about 16.5 hours until there are 260 bacteria present.
9 buckets of water because If 1/3 is 3 than you just add 6 more buckets which is 9
For 3 cups... vanilla needed - 1 teaspoon
for 1 cup...vanilla needed- 1/3 teaspoon
for 5 cups, vanilla needed- 5/3 teaspoon
In short , 1.67 or 5/3 teaspoon of vanilla is needed for 5 cups of floor
