A town has a population of 12000 and grows at 4% every year. To the nearest tenth of a year, how long will it be until the popul

ch4aika [34]

Answer:

11.0 years

Step-by-step explanation:

The exponential function describing the population growth can be written ...

population = (initial population)×(1 +growth rate)^years

If t represents the number of years, we can fill in the values to get ...

18500 = 12000×1.04^t

Dividing by 12000 gives ...

18500/12000 = 1.04^t

Taking logarithms, we have ...

log(18500/12000) = t×log(1.04)

t = log(185/120)/log(1.04) ≈ 11.037 ≈ 11.0

It will be 11.0 years until the population reaches 18,500.

A shop keeper has 8 gallons, 3 quarts,

ioda

Answer:

I believe it would be 86 cups left of milk.

Step-by-step explanation:

8 gallons= 128 cups of milk

3 quarts= 12 cups

Plus the 1 cup of milk he had equals 141 of milk in total

Now the customer wants 2 gallons (32 cups of milk), 5 quarts ( 20 cups), and 3 cups which is 55 cups of milk.

Now we minus what the customer bought from what the shop keeper had so:

55-141=86

PLS HELP ME PLS I WILL MARK BRAINLIEST PLS

Vesnalui [34]

Answer:

AB = 25

Step-by-step explanation:

First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = $5\sqrt5$ , this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle $\sqrt5$ times larger than the corresponding side on the small triangle. That means AB is $\sqrt5$ times larger than BC as well. So multiply BC by $\sqrt5$ get us the answer.
