Answer:

9

Step-by-step explanation:

Triangle DCE and ACD are similar (they share the angle at A, and since DE║CB, ∠D=∠C and ∠E=∠B (corresponding angles))

That means the side lengths are in ratio:

12/(8+12)=?/(6+?)

0.6(6+?)=?

3.6+0.6?=?

0.4?=3.6

?=9

William wants to invest $30,000 in a mutual fund.
Natali [406]

Answer:

He will have $39,750 at the end of five years.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

In this question:

P = 30000, I = 0.065, t = 5

Interest earned:

E = P*I*t = 30000*0.065*5 = 9750

Total amount:

T = E + P = 9750 + 30000 = 39750

He will have $39,750 at the end of five years.

Suppose we want to choose 5 objects,without replacement from 16 distinct objects
lesya692 [45]

Answer:

4368 ways

Step-by-step explanation:

We want to choose 5 objects,without replacement from 16 distinct objects.

We can use combination in this case. The formula for the combination is given by :

_{n}C_r=\dfrac{n!}{r!(n-r)!}

We have, n = 16 and r = 5

So,

_{16}C_5=\dfrac{16!}{5!(16-5)!}\\\\_{16}C_5=\dfrac{16!}{5!11!}\\\\=4368

So, there are 4368 ways in which we want to choose  5 objects,without replacement from 16 distinct objects.

A girl's feet are negative 4 over 6 yards from the surface of a pool. A boy's feet are negative 1 over 6 yards from the surface
notka56 [123]
The correct answer is B.

See diagram

EXPLANATION

Let us choose zero to be our reference point. That is zero is representing the surface of the pool.

Since

-\frac{1}{6}>-\frac{4}{6}

Or

-\frac{4}{6}

-\frac{1}{6}

will be closer to zero.

We were told that

-\frac{1}{6}

is where the boy's feet are. Therefore his feet are closer to the surface of the pool than the girl's feet.

So the correct answer is

the second option
