Q11) kelly puts $350 in a savings account. the savings account accrues interest at a flat rate of 1.05% a month. how much will t
Leviafan [203]

The account be worth in 7 months is 375.725 .

<h3>What is the amount in simple interest?</h3>

Amount (A) is the total money paid back at the end of the time period for which it was borrowed. The total amount formula in case of simple interest can also be written as: A = P(1 + RT)

Here, A = Total amount after the given time period.

Given that,

P = $350, R = 1.05%, T = 7 month

The simple interest equation uses "t" as years, but is just cycles, using an APR rate.

now, if we never mind "t" as years and just use it as an interest cycle, then we can say the rate is 1.05% and the period is 7 cycles.

A = P(1 + RT)

   = 350(1+1.05%×7)

   = 350(1+0.0105×7)

   = 350(1+0.0735)

   = 350×1.0735

A  = $375.725

Hence, The account be worth in 7 months is 375.725 .

Mice21 [21]

Answer:

The correct answer is 75 cubic feet.

Step-by-step explanation:

Volume of each block of cube is 1 cubic foot. Since the block is of the shape of a cube, the side length is 1 foot.

Number of blocks needed to fill the bottom of the the chest is 25.

Height of the chest is 3 feet.

Therefore there are three layers to be filled by blocks. Each layer needs 25 blocks each. Thus number of blocks needed to fill the whole chest is 25 × 3 = 75.

Volume of 75 blocks = Volume of the chest = 75 × 1 = 75 cubic feet.

Therefor the volume of the chest is given by 75 cubic feet.
