a squared + b squared = c squared for the sides and hypotenuse of the triangle.

6^2 + 6^2 = c^2
36 + 36 = c^2
72 = c^2
c = square root of 72, 8.49

A triangular prism has a base that is 6 cm by 4 cm and a height of 8 cm. If all dimensions are tripled, what happens to the volu

lana [24]

Im assuming the base of the triangle is 4cm. The volume is $96cm^{3}$ .
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is $2592cm^{3}$ , which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by $x^{3}$

A bus travels 6 hours at a constant speed of 36 miles per hour. How far does the bus travel?

Amanda [17]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - <u>a </u><u>bus </u><u>takes </u><u>6</u><u> </u><u>hours</u><u> </u><u>to </u><u>travel </u><u>a </u><u>particular</u><u> </u><u>distance </u><u>with </u><u>a </u><u>constant</u><u> </u><u>speed </u><u>of </u><u>3</u><u>6</u><u> </u><u>km/</u><u>hr</u>

To calculate - <u>the </u><u>total </u><u>distance </u><u>travel </u><u>by </u><u>the </u><u>bus</u>

We know that ,

$\bold{\longrightarrow \: speed = \frac{distance}{time}} \\$

<u>this </u><u>formula</u><u> </u><u>can </u><u>be </u><u>transformed</u><u> to</u><u> </u><u>find</u><u> </u><u>out </u><u>distance</u><u> </u><u>,</u><u> </u><u>as </u><u>follows </u><u>~</u>

$\bold {\: \longrightarrow \: distance = speed \times time}$

now ,

<u>substituting</u><u> </u><u>the </u><u>values </u><u>in </u><u>the </u><u>formula </u><u>state</u><u>d</u><u> </u><u>above </u><u>,</u>

$\bold{\longrightarrow \: distance = 36 \times 6} \\ \\ \bold{\longrightarrow \: distance = 216 \: km}$

thus ,

<u>the </u><u>bus </u><u>travels </u><u>a </u><u>distance</u><u> </u><u>of </u><u>2</u><u>1</u><u>6</u><u> </u><u>km</u><u> </u><u>in </u><u>6</u><u> </u><u>hours</u>

You invest $4000 in a bank account with 5% interest compounded annually. You are wondering how long it would take for your money

SCORPION-xisa [38]

The formula for compound interest is written as $A = P(1 + \frac{r}{n})^{nt}$ , where <em>P </em>is the principal (initial amount), <em>r</em> is the rate of interest, <em>n</em> is the number of times it's compounded per year, and <em>t</em> is the time in years. With the values from this problem plugged in, it looks like:

$A = 4000(1.05})^{t}$

Since you're trying to find when your money will double, put 8000 for <em>A </em>and solve for <em>t</em><em /> :

$8000 = 4000(1.05})^{t} \\ \\ 2 = (1.05})^{t} \\ \\ t=log_{1.05}2 \\ \\ t = 14.20669908289$

It will take approximately 14.21 years, or about 14 years, 2 months, and 16 days, for the money to double.
