Answer:

7.22 x 10^5

Step-by-step explanation:

Remember that the decimal is always to the right of the ones place.

1. Move it one place to the left and multiply by 10 to compensate.

2. Move it two places to left and multiply by 10^2.

3. Move the decimal point three times and multiply 10^3 to compensate, and the pattern continues until you reach the very last digit, the 7.

4. Numbers after the 7 that are not zeros will be after the decimal point.

so, 7.22 x 10^5

V = $\frac{4}{3} \pi r^{3}$

905 = $\frac{4}{3} \pi r^{3}$

2715 = 4π r³

$\frac{2715}{4\pi } = r^{3}$

216 = r³

$\sqrt[3]{216} = \sqrt[3]{r^{3} }$

6 = r

$i = (\frac{p1}{p2} )^{\frac{1}{n}} - 1$

$i = (\frac{200,000}{3,000} )^{\frac{1}{(2012-1945}} - 1$

$i = (\frac{200}{3} )^{\frac{1}{(67}} - 1$

i = (66.67)⁰¹⁵ - 1

i = 1.065 - 1

i = 0.065

i = 6.5%

Answers: r = 6, i = 6.5%

How could you solve for x in the problem 3x+7=-x-1

lukranit [14]

Hello there!

$3x+7=-x-1\\$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 7 from both sides of the equation.

$3x+7-7=-x-1-7$

Simplify

$3x=-x-8$

Then you add by x from both sides of the equation.

$3x+x=-x-8+x$

Simplify

$4x=-8$

Divide by 4 from both sides of the equation.

$\frac{4x}{4}=\frac{-8}{4}$

Simplify it should be the correct answer.

$x=-2$

Answer⇒⇒⇒x=-2

Hope this helps!
