The interest that Marcos will get is 50000.

<h3>How to calculate the interest?</h3>

The following can be deduced from the information given:

Principal = 50000

Interest rate = 12.5%

Time = 8 years

The simple interest will be:

= (PRT/100)

= (50000 × 12.5 × 8)/100

= 50000

The amount that will be obtained after 8 years will be:

= Principal + Interest

= 50000 + 50000

= 10000

-4.5 rose 9.7 then fell 4.8

-4.5 + 9.7 = 5.2

5.2 - 4.8 = 0.4

Answer:

30.77 =x

Step-by-step explanation:

tan theta = opposite side / adjacent side

tan 39 = x /38

Multiply each side by 38

38 tan 39 =x /38 * 38

38 tan 39 =x

30.77179326 =x

To the nearest hundredth

30.77 =x

Three monkey's walk into a motel on the Curious George Hotel and ask for a room. The desk clerk says a room costs 30 bananas, so

lions [1.4K]

Step 1

Given;

$\begin{gathered} Cost\text{ for a room= \$30} \\ Each\text{ monkey pays 30 bananas} \\ Clerk\text{ ask bell boy to refund 5 bananas} \\ Bell\text{ boy refunds 3 bananas} \\ Bell\text{ boy keeps 2 bananas} \end{gathered}$

Required; To determine where 1 banana went if 29 bananas are accounted for.

Step 2

Here is the break down; the balance should be like this;

$\begin{gathered} 25\text{ bananas-room} \\ 3\text{ banans\lparen3}\times1\text{ banana\rparen- back to monkeys} \\ 2\text{ bananas- Bell boy} \\ Total-30\text{ bananas} \end{gathered}$

Hence, there is no extra 1 banana, The monkeys spent 27 bananas of which the bellboy took 2 bananas and 25 bananas went to the room, and 3 bananas where returned to them. A total of 30 bananas

The complete factorization of -12x^3 + 14x^2 +6x is -2x(ax + 1)(2x-3). What is the value of a?

tester [92]

Answer:

a = 3

Step-by-step explanation:

-12x³+14x²+6x = -2x(ax+1)(2x-3)

<em>Divide both sides by -2x(2x-3)</em>

$\frac{-2x(ax+1)(2x-3)}{-2x(2x-3)} = - \frac{12x^{3} }{-2x(2x-3)} + \frac{14x^{2} }{-2x(2x-3)} +\frac{6x}{-2x(2x-3)}$

ax+1=3x+1

<em>Subtract 1 from both sides</em>

ax=3x

<em>Divide both sides by x</em>

a=3
