Ashley drove 648 miles in 9 hours. At the same rate, how many miles would she drive in 7 hours?

1 answer:

8 0

First, divide 648 by 9. 648/9=72. Now we know that Ashley covers 72 miles in an hour. In order to get the number of miles she covers in 7 hours we must multiply 72 by 7 which equals 504. So Ashley would drive 504 miles in 7 hours.

The bits are determined by repeated division by 2 to yield either 0 or 1.

183/2 = 91 rem 1 => 1 (lowest bit) 2⁰
91/2 = 45 rem 1 => 1 (next higher bit) 2¹
45/2 = 22 rem 1 => 1 (next higher bit) 2²
22/2 = 11 rem 0 => 0 (next highrt bit) 2³
11/2 = 5 rem 1 => 1 (next higher bit) 2⁴
5/2 = 2 rem 1 => 1 (next higher bit) 2⁵
2/2 = 1 rem 0 => 0 (next higher bit) 2⁶
1/2 = 0 rem 1 => 1 (next higher bit) 2⁷
The next higher 24 bits have 0 in each bit.

For 32-bit system,
183 = 00000000 00000000 00000000 10110111 (with a space between bytes for readability)

Answer: 00000000000000000000000010110111

If Valerie deposited 12,000 into an account threat earns 15% simple annual interest how much money will she have after 3 years

Ad libitum [116K]

Answer:

The amount which she will have into account after 3 years is 17,400 unit

Step-by-step explanation:

Given as :

The principal which is deposited into an account = 12,000 unit

The rate of interest simple annual = 15%

The Time period = 3 years

Let The amount which she have after 3 years = A unit

<u>From simple Interest method</u>

Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

Or , Simple Interest = $\frac{12,000\times 15\times 3}{100}$

Or, Simple Interest = $\frac{540,000}{100}$

∴ Simple Interest = 5,400 unit

Now,

Amount = Principal + Simple Interest

Or, A = 12,000 unit + 5,400 unit

∴ A = 17,400 unit

Hence The amount which she will have into account after 3 years is 17,400 unit . Answer
