Answer:

Boris will have $250 in 10 months.

Step-by-step explanation:

$25 = one month.

$250= ?months

To find ?, the months we divide 250 by 25 to get this:

250 ÷ 25 = 10

10 months is the amount of time Boris will have to wait until he saves up $250.

Hope this helps you! Good luck with your quiz! :)

1 feet is 12 inches so 40 feets is 480 inches
Real locomotive is 480/16=30 times wider then the model
And then a window on the real locomotive is 30 times wider then the model.

Which is bigger 40% of 120 or 1/4 of 200?

Dmitry [639]

40/100×120=4/1×12=48. 1/4×200=50. so 1/4 of 200 is greater than 40% of 120.

Anna starts a fixed deposit with $178000, the bank offers 9.5% per year simple interest for 8 months. she has the option of rest

soldier1979 [14.2K]

Using simple interest, we have that:

A) The interest due after 8 months is $11,272.33.

B) The total value of the investment will be of $189,986.24.

The amount of interest earning using simple interest, after t years, with an yearly interest rate of i and an initial investment of P is given by:

$E = Pit$

In this problem:

Deposit of $178,000, hence $P = 178000$ .
Interest rate of 9.5% per year, hence $i = 0.095$ .
8 months, the time is in years, hence $t = \frac{8}{12} = \frac{2}{3}$

Item a:

$E = Pit$

$E = 178000(0.095)\frac{2}{3} = 11272.33$

The interest due after 8 months is $11,272.33.

Item b:

For the second interest, we consider $P = 11272.33$ , hence:

$E_2 = Pit$

$E_2 = 11272.33(0.095)\frac{2}{3} = 713.91$

The total value will be composed by:

The initial deposit of $178,000.
The first interest of $11,272.33.
The second interest of $713,91.

Hence, it will be:

$T = 178000 + 11272.33 + 713.91 = 189986.24$

The total value of the investment will be of $189,986.24.

You have a chess board as pictured, with squares numbered 1 through 64. You also have a huge change jar with an unlimited number

ANEK [815]

Answer:

(a) 512 dimes

(b) $D(n) = 2^{n-1}$

(d) 9.22337 x 10¹² km

(e) roughly 61,489.13 times longer than the distance from the earth to the sun.

Step-by-step explanation:

b. Starting with 1 dime in the first square, if the number of dimes per each square is the double of the previous square, the general equation for the number of dimes in each square 'n' can be found by:

$D(1) = 1\\D(2) = 2^1\\D(3) = 2^2\\D(4) = 2^3\\D(n) = 2^{n-1}$
