7 0

well, rational = fractional, namely something you can write as a fraction, well, anything between -1 and -2 is just less than -1 so

$\bf \boxed{-2}\dotfill \stackrel{-1-\frac{1}{4}}{-\cfrac{5}{4}}\dotfill\stackrel{-1-\frac{1}{10}}{-\cfrac{11}{10}}\dotfill \stackrel{-1-\frac{1}{99}}{-\cfrac{100}{99}}\dotfill \boxed{-1}$

A city has a population of 250,000. The population is expected to decrease 1.5% annually for the next decade. Write a function t

notka56 [123]

Answer:

Population after $t\ years=250000\times (0.985)^t$

Step-by-step explanation:

If $P$ is the initial amount, $r$ is the annual rate of decrease then after $t$ years the remaining amount $(A)$ will be given by

$A=P(1-\frac{r}{100})^t$

Here $P=250000, r=1.5\%\\\\A=250000(1-\frac{1.5}{100})^t\\\\A=250000(1-0.015)^t\\\\A=250000\times (0.985)^t$

Please tell me the answer ASAP Lynette's average score on five tests is 18. If she scores 24 points on her sixth test, what is h

Helga [31]

Answer:

The average score of 6 tests is 19.

Step-by-step explanation:

Given that the average score of 5 tests is 18. So first, we have to find the total number of scores for 5 tests :

$let \: x = total \: no. \: of \: scores$

$\frac{x}{5} = 18$

$x = 18 \times 5$

$x = 90$

We have found out that the total scores for 5 tests is 90. So we have to find the average of 6 scores :

$\frac{x + 24}{5 + 1} = \frac{90 + 24}{6} = \frac{114}{6} = 19$
