Eva8 [605]

Answer:

The equation

c x 2 > k

l x 3 ?> c > k

g = 30 = c + l + k

this equation is the same as...

Cecile read twice as many books as Kami.

Laura read 3 times as many books as Kami, but possibly less than Cecile.

Gigi read 30 books. 30 books is the same as all 3 girls combined.

To find out how many books each girl read, you need to find 3 unequal numbers that add up to 30. These numbers are substituted, only because they can be anything at all, and I want to prevent confusions.

hope this helps!

Question 22 A city has a population of people. Suppose that each year the population grows by . What will the population be afte
Alexeev081 [22]

Answer:

911,690.

Step-by-step explanation:

Please consider the complete question.

A city has a population of 390,000 people. Suppose that each year the population grows by 6.75%. What will the population be after 13 years? Round your answer the nearest whole number.

We will use exponential growth formula to solve our given problem.

y=a\cdot (1+r)^x, where,

y = Final value,

a = Initial value,

r = Growth rate in decimal form,

6.75\%=\frac{6.75}{100}=0.0675

y=390,000\cdot (1+0.0675)^x

y=390,000\cdot (1.0675)^x

To find the population after 13 years, we will substitute x=13 in population growth equation as:

y=390,000\cdot (1.0675)^{13}

y=390,000\cdot 2.3376661492982871

y=911689.798226331969

Upon rounding to nearest whole number, we will get:

y\approx 911,690

Therefore, the population of the city after 13 years would be 911,690.

Evaluate and simplify. Enter your answer as an integer or as a proper fraction or mixed number in simplest form. (− 3/4 / 4/5)=
BlackZzzverrR [31]

Answer:

-3/80

Step-by-step explanation:

(− 3/4 / 4/5) = -0.0375 (calculator)

-0.0375 / 1 * 10000 / 10000 = 375 / 10000

375 / 10000 (divided by) 125 / 125 = 3 / 80

negative decimal = negative fraction (-0.375 = -3 / 80)
