How do we divide using long division?? (Explain plz)

1 answer:

Semmy [17]3 years ago

7 0

Answer:

Step-by-step explanation:

Step 1: Make sure the polynomial is written in descending order. If any terms are missing, use a zero to fill in the missing term (this will help with the spacing).

Step 2: Divide the term with the highest power inside the division symbol by the term with the highest power outside the division symbol.

Step 3: Multiply (or distribute) the answer obtained in the previous step by the polynomial in front of the division symbol.

Step 4: Subtract and bring down the next term.

Step 5: Repeat Steps 2, 3, and 4 until there are no more terms to bring down.

Step 6: Write the final answer. The term remaining after the last subtract step is the remainder and must be written as a fraction in the final answer.

An account earns simple annual interest. You deposit $600 into an account at 5% interest rate for 2 years. (a) Find the interest

Ilia_Sergeevich [38]

Answer:

(a) $60 | (b) $660

Step-by-step explanation:

We can use the simple interest formula for this:

$I=Prt$

<em>I = interest amount</em>

<em>P = principal amount</em>

<em>r = interest rate (decimal form)</em>

<em>t = time (years)</em>

<em />

First, change 5% into its decimal form:

5% -> $\frac{5}{100}$ -> 0.05

Next, plug in the values into the equation:

$I=600(0.05)(2)$

$I=60$

<em>The interest earned is $60. To find the total balance, just add the $600 back.</em>

$600+60=660$

The total interest earned is $60 and the total is $660.

How many half-lives of radon-222 have passed in 11.46 days? If 5.2 × 10−8 g of radon-222 remain in a sealed box after 11.46 days

Svetach [21]

Answer:

(i) Approximately 3 half lifes

(ii) $4.21\times 10^{-7}\text{ g}$

Step-by-step explanation:

(i) ∵ The half life of Radon-222 is approximately 3.8 days,

So, the number of half life in 11.46 days = $\frac{11.46}{3.8}$ ≈ 3

(ii) Since, the half life formula is,

$N=N_0 (\frac{1}{2})^{\frac{t}{t_{\frac{1}{2}}}}$

Where,

$N_0$ = initial quantity,

t = number of periods

$t_{\frac{1}{2}}$ = half life of the quantity,

Given,

N = $5.2\times 10^{-8}\text{ g}$

t = 11.46 days,

$t_{\frac{1}{2}} = 3.8\text{ days}$

$\implies 5.2\times 10^{-8}=N_0 (\frac{1}{2})^\frac{11.46}{3.8}$

$\implies N_0=2^{\frac{11.46}{3.8}}\times 5.2\times 10^{-8}\approx 4.21\times 10^{-7}\text{ g}$

Jim will divide 6 3/4 pounds of candy equally among

yan [13]

Answer:

Halloween question, perfect timing! Your answer would be 2 pounds per friend.

Step-by-step explanation:

Here's how we get this:

First, multiply 3/4 by 6. You'll get 4.5. Let's use a decimal for this equation.

Now, you'll divide 9 by 4.5, to get 2. There's our answer. But we want to double-check and see if it's right.

We can do that by multiplying 4.5 by 2, or 2 by 4.5.

4.5 x 2 = 9

Therefore, your answer is 2 pounds per friend.

Hope I helped! ☺
