Answer:
Step-by-step explanation:
In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440
You need to solve the equation.
20/440 = N · 440/440
0.045 repeating = N
Rounded, the sales tax rate would be 4.5%
3,920,000,000,000 in scientific notation is 3.92x10^12
9514 1404 393
Answer:
E none of the above
Step-by-step explanation:
"Triples in size" means the growth factor is 3, so we expect to see that as the base of the exponent. That growth factor applies to a period of 6 minutes, or 1/10 hours. The number of 6-minute intervals in t hours is 10t, so we expect to see that as the exponent. The appropriate model could be written ...
n(t) = 3·3^(10t) . . . . . matches no offered answer choice
Similar to the last problem
y = x + 2
y + 3 = 2x
so we need to find which values fit
