I hate to say this, but this question is quite unnecessary and takes up space (so that other peoples' questions may not get covered). Please refrain from posting these kinds of questions if you already know the answer.

Sorry, I meant 41, not 47.

I believe you've posted this questions already: https://web2.0calc.com/questions/whattt_6

The answer would be 41.

Hope this helped!

We know that in a 30-60-90 triangle, the length of the hypotenuse is 2x where the length of the side opposite of the 30 degree angle is x, and the length of the side opposite of the 60 degree angle is x*sqrt(3).

Knowing this, x in our case would be 6, so the side opposite of the 60 degree angle would be 6√3 inches, or 10.39230484...

Hope this helped!

We can use trigonometry for this problem. This would give us:

(tan)42 = x/18

(tan)42*18 = x

16.2 = x.

So the flagpole is around 16.2 meters.

Let's see, some options we have are:

31, 37, 41, 43, 47, 53, and 59.

So our answer must be 47 as the digit in the one's place (4) is three less than the digit in the ten's place (7).

Terribly sorry, I found several wonderful answers here: https://web2.0calc.com/questions/need-help-please_46

(if anyone wants to see as well).

Thank you so much!

Let's say Mary has 60 marbles and Jolie has 100 marbles (since it would work in this context). If we add them together, there are 160 marbles in total.

Because we're looking for Jolie's percentage, we need to find the value of x for:

100/160 = x/100

which we know is 62.5.

Therefore 62.5% of the marbles in the bag are Joli's.

Hope this helped!

I greatly appreciate your effort to answer my question! However, if you use someone else's work, please give them credit.

Thanks,

x = 1/9, -3/11.

We can solve this in a similar way that we did for the football and baseball question.

If you find the value of one jujube or smartie, you can substitute that value into another equation to find the value of the other variable.

Hope this helped!

So we have the following equations:

Equation 1: 11f + 4b = 803

and

Equation 2: 6f + 6b = 522.

If we take equation 2, we can simplify it into:

f + b = 87 (by dividing f, b, and 522 by 6.)

This gives us f = 87 - b.

We can substitute this value into equation 1 as shown:

11(87 - b) + 4b = 803

We then use the distributive property which gives us:

957 - 11b + 4b = 803

Combine like terms:

957 - 7b = 803

Simplify:

-7b = -154

Divide both sides by -7:

b = 22.

The question asks for the value of a baseball and a football so we substitute this into equation 2 which gives us:

6f + 6(22) = 522

6f + 132 = 522

6f = 390

f = 65.

We know that the area of a square is s^2 (with s being the side length). Knowing this, all we have to do is take the square root of each area to find its side length:

Square 1: sqrt(25) = 5cm

Square 2: sqrt(144) = 12cm

Square 3: sqrt(625) = 25cm

Hope this helped!

Thank you, CPhill!

Let p be the cost of each pendant.

Since there are two necklaces, we can subtract 2(3.50) from 13.80 (assuming that 3.50 is the cost of all of the beads per necklace) - which gives us 6.80.

Since there are two pendants, we divide 6.80 by 2 which gives us 3.40 as the cost for each pendant.

Hope this helped!

Thank you, Melody!

Thank you so much, CPhill!

My mistake, I thought that AC was 25 for a moment (from a similar problem). Anyhow, Jugoslav's answer has a wonderful explaination.
