Answer:

A=42000(1.04)^n

Step-by-step explanation:

This is a compound interest formula expressed as:

A=P(1+i)^n

Where:

  • n is time in years
  • i is the rate of interest
  • A is the accumulated amount after n years
  • P is the initial amount.

#We substitute the given values to determine amount after n years as follows:

A=P(1+i)^n\\\\=42000(1+0.04)^n\\\\=42000(1.04)^n

Hence, the amount earned after n years is given by the expression A=42000(1.04)^n

Radius of the circle is 20cm. there are two chords of lengths.
Vaselesa [24]

9514 1404 393

Answer:

  12 cm

Step-by-step explanation:

The distance to the chord is the median of an isosceles right triangle with hypotenuse 20 and leg 16. This 5:4 ratio suggests the other leg of that right triangle would make the ratios 3 : 4 : 5, so is 12.

The chords are 12 cm from the center.

_____

You can, of course, use the Pythagorean theorem. If c is half the chord length and d is the distance to the chord, you have ...

  c² + d² = r²

  16² + d² = 20²

  d² = 400 -256 = 144

  d = √144 = 12 . . . . . cm

Kelly can read five pages of her fiction book or two pages of her history textbook in seven minutes. If Kelly wants to read thir
Liono4ka [1.6K]

So five pages of her fiction book in 7 minutes. And she must read thirty pages:

30/5 = 6.

6 * 7 = 42 minutes for the fiction book.

So 2 pages of her history book in seven minutes.

30/2 = 15.

15 * 7 = 105 minutes for the history textbook

Add:

42 + 105 = 147 minutes.

a student is chosen at random from a 7th grade math class of 16 girls and 8 boys. find each probability
zavuch27 [327]
There is a total of 24 students in the class.

The probability of choosing a girl is 16/24. Which reduces down to 2/3 or 66%.

The probability of choosing a boy is 8/24. Which reduces to 1/3 or 33%.

So the student has a 66% chance of choosing a girl and 33% chance for a boy.
