Answer:

Given: The principal amount (P) = $ 105.00, rate of interest(r) = 8% and t= 25 years and number of times interest compounded per year (n) =4.

Use formula to find the final amount i.e,

A =P(1+\frac{r}{100n})^{nt} ......[1] ; where r is the rate of interest , n is the number of times interest compounded per year and P is the Principal.

Now, substitute the given values of P , r, n and t in [1] we get;

A = 105 \times (1+\frac{8}{100 \times 4})^{4\times 25}

or

A =105 \times (1+\frac{8}{400})^{100}

Simplify:

A = $ 760.687842416

therefore, the final amount is $ 760.68 (approx.)

Answer:

D) 15x^2 +6x-48

Step-by-step explanation:

Area \:  of  \: rectangle  \\  = length \times width \\  = 3(x + 2) \times (5x - 8) \\  = (3x + 6) \times (5x - 8) \\  = 3x(5x - 8) + 6(5x - 8) \\  = 15 {x}^{2}  - 24x + 30x - 48 \\  = 15 {x}^{2}  + 6x - 48

What is the similarity between 85,17,19,4 and 2?
Anvisha [2.4K]
You can obtain the a number for which they all divisors by calculating the least common multiple.

This way:

85 = 5*17*1
17=17*1
19=19*1
4=2^2 *1
2=2*1

The least common multiple is: 5*17*19*2^2 = 6,460.

Then 84, 17, 19, 4 and 2 are all divisors of 6,460.

Six times a number increased by 20 is four less than eight times the number. Find the number
DaniilM [7]
Greetings!

"<span>Six times a number increased by 20 is four less than eight times the number. Find the number."...

This would be, as an equation:
</span>6x+20=8x-4

Solve:
Add 4 and -6x to both sides.
(6x+20)+4+(-6x)=(8x-4)+4+(-6x)
Simplify.
24=2x
Divide both sides by 2.
(24)/2=(2x)/2
Simplify.
12=x
x=12
<span>
x=12

Hope this helps.
