Obama can. Yes, he can!

ty was confused why it was (x^2+y^2) 

True.....the larger the central angle, the greater the arc spanned by that angle.

6 + 3/4   = 27/4

2 + 5/8  =  21/8

So we have

27/4  ÷ 21/8      change to multiplication and invert the second fraction

27/4  x 8/21    =

8/4  x 27/21  =

2 x 9/7  =

18 /7

I can 

We could solve this as a proportion....let's use some logic, instead

If he swims 1/2 mi in 1/4 of an hour......then one hour is four times as long.....so .....he must swim 4 times as far...so....

4 * (1/2)  = 4/2   = 2 miles

$33.55 would be your answer 

Dye your red hair brown.

The probability that the first pilot gets fish = 1/2 = 50

The probabilty that the second pilot gets fish = 2/5 = .40

So 

P(A and B)  = .50 * .40  =  .20  = 20%

-3(x-5)=2x    simplify

-3x + 15 = 2x   add 3x to both sides

15  = 5x      divide both sides by 5

3 = x

We can use the sine here

sin(22) = h / 205     multiply both sides by 205

205^sin(22) = h = about 76.8 ft

By random guessing, she should get 1 out of 4 answers correct.

So  1/4 of 20   = 5 correct answers.

x^6 + y^6    ..... this is the sum of two cubes

First......take the cube root of both things  = x^2  and y^2   write them in parentheses with a plus between them

Then...in the next set of parentheses, write the square of the first thing above, then write the opposite sign of the one in the first set of parentheses. Then multiply  the two terms in the first set of parentheses together. Finally, write a plus and then the square of the second term in the first set of parentheses.   So we should have this.....

(x ^2  +  y^2) (x^4  - x^2*y^2 + y^4)

I think that you need to know how many grams are in one serving. Then you can determine 50% of that number.

Consider this......20 total marbles

7 red  .....7/20 = 35%

7 white

1 blue

5 green

(x²+y²)(x⁴-x²y²+y⁴)

Welcome, aboard.....!!!!

hey :)

Just guessing:

There is a 70% chance of selecting either a red or white marble. Therefore there must be a 30% chance of either a green or a blue marble. Since green has a five time higher likelihood, then the 30% must be divided between 0.25 and 0.05.

There should be a minimum of 25 green marbles.

I need help on the exact same question :)
