Answer:

B. $8,960

Step-by-step explanation:

Use your number sense.

If the account earns interest, the balance will increase from the initial deposit of $8000. The only sensible answer choice is B, $8960.

If you want to actually figure it out, the balance is given by ...

A = P(1 +rt)

A = 8000(1 +0.04·3) = 8000(1.12) = 8960 . . . . matches choice B

elixir [45]

Answer:

469.60 yards far away is the cabin to the nearest yard

Step-by-step explanation:

given data

walks = 215 yards

bearing on the cabin = N 24.6 degrees E

solution

we know here when 2 line are parallel then opposite angle are equal

so here $\angle$ DAC =

and now we take here triangle ABC

so here we can say

tan (24.6 ) = $\frac{AB}{BC}$

so here BC will be

BC = $\frac{Ab}{tan(24.6)}$

put here value and we get

BC = $\frac{215}{tan(24.6)}$

solve it we get

BC = 469.60 yards

-1/2x + 1/8 = -1/3x - i/4

brilliants [131]

Answer:

x= 4/9

Step-by-step explanation:

-1/(2x) + 1/8 = -1/(3x) - 1/4

-1/(2x)+1(3x)= - 1/4 -1/8

-3/(6x)+2(6x) = -2/8 -1/8

- 1/(6x) = - 3/8

-1*8 = -3*6x

8=18x

x= 8/18= 4/9

Check:

-1/(2*4/9) + 1/8 = -1/(3*4/9) - 1/4

- 1(8/9) + 1/8 = - 1/(4/3)-1/4

-9/8+1/8 = - 3/4-1/4

-1 = -1

Q = x^3 â xGiven that x is a positive integer such that x â¥ 75, which of the following is the remainder when Q is divided by 6?

geniusboy [140]

Answer:

A) 0

Step-by-step explanation:

Given that

$Q=x^{3}-x\\\\x(x^{2}-1)\\\\x(x+1)(x-1)$

Divisor = 6 = 3*2

$\frac{Q}{D}=\frac{(x)(x+1)(x-1)}{6}\\\\\frac{Q}{D}=\frac{(x)(x+1)(x-1)}{2 \times 3}\\$

As it can be see that x ≥ 75 and Q is product of three consecutive terms (x-1), x, (x+1) which is always completely divisible by 2, 3 and 6. So remainder is zero
