Mark is investing $8,000 in an account paying 5.5% interest compounded monthly.

agasfer [191]

Answer:

The formula is F = P(1 + interest percent)^n

Here,

p =8000 dollar

interest percent =5.5% = (5.5/12)/100 =0.004583 (compounded monthly)

n =7 x 12 =84 (compounded monthly)

=> Mark's account balance after 7 years

F = 8000*(1+0.004583)^84 =11746.2503 dollar

Given that 1/f = 1/u + 1/v , express u in terms of v and f

JulijaS [17]

Answer:

u = fv/(v - f)

Step-by-step explanation:

1/f = 1/u + 1/v

1/u = 1/f - 1/v = v/fv - f/fv = (v-f)/fv

1/u = (v-f)/fv

u = fv/(v - f)

The length of the base of a rectangular prism is 9

Tatiana [17]

Answer:

The volume of the prism is 320 15/16 inches³.

Step-by-step explanation:

Given:

The length of the base of a rectangular prism is 9 7/8.

The width of the prism is 8 1/8.

And the height is 4 inches.

Now, to find the volume of the prism.

(Length) l = 9 7/8 = 79/8 inches.

(Width) w = 8 1/8 = 65/8 inches.

(Height) h = 4 inches.

So, by putting the formula to get the volume:

Volume = w×h×l.

$Volume=\frac{65}{8}\times 4\times \frac{79}{8}$

$Volume=320\frac{15}{16}$

Volume = 320 15/16 inches³.

Therefore, the volume of the prism is 320 15/16 inches³.
