A city has a population of 230,000 people. Suppose that each year the population grows by 9%. What will the population be after

zloy xaker [14]

Answer:

Step-by-step explanation:

If it grows by 9% each year, you can simply do the current population times 109%. Because its an additional 9%.

230,000*109% = 250,700

After the first year, there is a population of 250,700 people.

250,700*109% = 273,263

After the second year, there is a population of 273,263 people.

273,263*109% = 297,856.67

After the third year, there is a population of 297,856.67 people.

297,856.67*109% = 324,663.77

After the fourth year, there is a population of 324,663.77 people.

324,663.77*109% = 353,883.509

After the fifth year, there is a population of 353,883.509 people.

353,883.509*109% = 385,733.025

After the sixth year, there is a population of 385,733.025 people

Round it up to 385,733 people.

a bank offers an annual simple interest rate of 8% on Home Improvement loans, Tobias borrowed $17,000 over a period of 2 years.

shepuryov [24]

The answer would be $19,270.
Steps:
1. Take 17,000 and multiply by 8%.
2. Take the sum of that which is $1,360 and multiply by two (for the two years).
3.The sum of that would be $2,720 and add onto $17,000.
4. The sum of that would be $19,270!

The area of a triangle is 1,4440 cm^2. The base of the triangle is 5 times the height. What is the height of the triangle?

DochEvi [55]

Answer:

h = 24 cm

Step-by-step explanation:

The formula for area of a triangle is

A = (1/2)bh where b is the base and h is the height.

We are told that the base is 5 times the height, this translates to

b = 5h, so we can rewrite our formula to

A = (1/2)(5h)(h) or

A = (1/2)5h²

We are given A = 1,440, so plug that in and solve for h...

1,440 = (1/2)5h²

2,880 = 5h² (multiply both sides by 2 to get rid of the fraction)

576 = h² (divide both sides by 5 to get the h value by itself)

24 = h (take the square root of both sides)
