Sin means to divide the opposite side measure by the hypotenuse. Cos is equal to the adjacent side value divided by the hypotenuse. Tan is equal to the opposite value divided by the adjacent. To remember this, I use the abbreviation SOHCAHTOA. SOH for Sin is Opposite over Hypotenuse, and so on.

Divide the expressions:<br> x + 1 / x + 2 ÷ 3x / x − 4.
slavikrds [6]

Answer:

Remember, \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}*\frac{d}{c}=\frac{a*c}{b*d}

Then,

\frac{x+1}{x+2}\div\frac{3x}{x-4}=\frac{x+1}{x+2}*\frac{x-4}{3x}=\frac{(x+1)(x-4)}{3x(x+2)}=\frac{x^2-3x-4}{3x^2+6x},

Now, using long division of polynomies we have that

\frac{x^2-3x-4}{3x^2+6x}=\frac{1}{3}-\frac{5x+4}{3x^2+6x}

The dimensions of a rectangular prism are 1 mm, 6 mm, and 11 mm. Find the volume and the surface area.
hram777 [196]
The volume is the product of the side lengths which is 1*6*11= 66 mm^3. The surface area is twice the sum of all the possible products of the side lengths, or 2lw+2wh+2hl which is 2(6*11+6*1+11*1) = 166 mm^2 if my mental math is decent.

Is this triangle a right triangle? yes or no?
svlad2 [7]

Answer:

Yes.

Step-by-step explanation:

You can use the Pythagorean theorem to figure this out.

5²+12²=13²

25+144=169

169=169

You can also look at the bottom left corner, which is a right angle. All triangles containing right angles are right triangles.

You can also base your answer off of the fact that triangles are kind of like <u>G</u>oogle: They're always right. (jk no that's not true neither are always right)

Gennadij [26K]

Answer:

So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857.
