1490
If you split the composite shape into two different shapes, you write down the formula: length x width x height, you get (22 x 13 x 5) + (6 x 5 x 2). Once you solve that, you get the answer of 1490.
Answer:
- 8 small paintings
- 4 large paintings
Step-by-step explanation:
If all 12 had been small paintings, DeGuizman's revenue would have been $720. At $1200, it is $480 more than that. Each large painting generates $120 more revenue than a small painting, so there must have been $480/$120 = 4 of them sold.
8 small paintings and 4 large paintings were sold.
Answer:
212.9 days
Step-by-step explanation:
The bacteria culture initial population is 25 represented by Po and the population after t days is represented by P(t).
Using growth formula:
P(t) = Po ( 1 + r)^t where r is rate in percent and t is time in days
r = 1.28%, P(t) = 375, and Po = 25
substituting this values into the equation above yields
375 = 25 (1 + 1.28/100)^t
375÷25 = ( 1 + 0.0128)^t
15 = (1.0128)^t
take logarithm of both sides
log 15 = log (1.0128)^t remember the law log a^b = b log a
applying the same law gives
log 15 = t log 1.0128
divide both side by log 1.0128
log 15 ÷ log 1.0128 = t log 1.0128 ÷ log 1.0128
t = 212.9 days
