1-1/3 or 4/3

$${\mathtt{1.1}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{4}}} = {\mathtt{0.000\: \!11}}$$

(fyi $${{\mathtt{10}}}^{-{\mathtt{4}}} = {\frac{{\mathtt{1}}}{{{\mathtt{10}}}^{{\mathtt{4}}}}} = {\frac{{\mathtt{1}}}{{\mathtt{10\,000}}}}$$)

To solve for x, you would take the inverse tangent of 15/20, or 0.75.

X is about 36.869897645844 degrees, but it depends on what your assignment/test/whatever wants you to round to.

9*12=108

Next time you could use a calculator :)

what is the scientific notation for 0.00011 ?

No you got the same answer :)

Ok, I am probably wrong. Please excuse my low mental capabilities.

The volume of the cone is 294.38 . The radius of the base is 7.5 cm . Which of the following could be the height of the cone ? 

$${\mathtt{V}} = {\frac{{\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{h}}}{{\mathtt{3}}}}$$

$${\mathtt{294.38}} = {\frac{{\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{7.5}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{h}}}{{\mathtt{3}}}}$$                    Times both sides by 3

$${\mathtt{883.14}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{56.25}}{\mathtt{\,\times\,}}{\mathtt{h}}$$           Divide both sides by 7.5^2 which = 56.25 and pi

$${\mathtt{5}} = {\mathtt{h}}$$ (nearest whole. the actual figure is around 4.998)

The answer is b, 5cm.

The formula for the area of a circle is $${\mathtt{\pi}}$$r^2.

3.5 squared is 12.25.

12.25 times $${\mathtt{\pi}}$$ is approximately 38.48.

The area of the circle is about 38.48 square meters.

The formula for the volume of a cone is V=1/3BH or V=$${\mathtt{\pi}}$$r^2H, in which B equals the area of the base,H is the height of the cone, and r is the radius of the base.

Plugging in the values, we get 294.38=1/3*$${\mathtt{\pi}}$$*56.25*H

To solve for H, isolate the variable by dividing both sides by $${\mathtt{\pi}}$$, 1/3, and 56.25

294.38/(1/3)/$${\mathtt{\pi}}$$/56.25 is approximately 5.

The correct answer would be B, 5cm.

$$\frac{125}{200}=\frac{5}{8}=0.625$$

(divide the numerator and denominator by their highest common factor = 25)

When you're dealing with rational exponents, the numerator is the power, the denominator is the root. You can start off with the power or the root, it doesn't matter which one.

The 3rd root of 8 is 2, and 2 to the 4th is 16. 8 to the power of 4/3 is 16.

Just like before, the 3rd root of 8 is 2, and 2^1 is obviously 2.

So what you get is 16-2, which is 14.

8^4/3-8^1/3=14

First step would be to get rid of the $20 allowance from your total amount earned( $92 ). So 92-20 is $72. Now you worked  3h, then 6h. 3+6 is 9, the total number of hours you worked. To find how much you earned per hour, divid the total left by the number of hours. So therefore 72/9=8. You earn $8 an hour :) Hope this helped 

you click the 2nd on your calculator then the sine-1 should pop up

To cancel -1 from an expression like x - 1, add +1.

To change from a percentage to a decimal fraction, divide by 100.

80% = 80 ÷ 100 = 0.80

So (80%)%  = 0.80%

Now, divide by 100 again:

0.80% = 0.80 ÷ 100 = 0.0080

To go from term to term, multiply by 5.

To be a convergent geometric series, the number that you multiply by must be a fraction between -1 and 1 (and not including either -1 or 1).

Since the common ratio (the number you multiply by) is not a fraction between -1 and 1, it doesn't converge.

1 x 98 = 98
2 x 49 = 98
7 x 14 = 98
14 x 7 = 98
49 x 2 = 98
98 x 1 = 98

Angle(ACB) + 120°  =  180°

So, Angle(ACB)  =  60°.

The three angles, A, B, and C added together equal 180°.

--->  58° + Angle(B) + 60°  =  180°

If you solve this, you will have the value of Angle(B).

((2)^2 )- (121-117)= 4- (4)=0

The answer is 0.285 because a percent is out of 100 so 28.5% is really, as a fraction, 28.5 over 100. Then to turn 100 into 1 you divide by 100. Whatever you do to the bottom, you do to the top. Therefore, 28.5 divided by 100 is 0.285 and that is your answer!

your question is not there

The answer is 12.
