Answer:

356.05 cm³

Step-by-step explanation:

We are looking for the volume. The formula is density = mass / volume.

If we plug in our numbers, our formula would be 2.76 = 982.7 / V.

Multiply both sides by V and your formula would be (V) 2.76 = 982.7.

Divide both sides by 2.76 and you would get V = 356.05.

a pitcher of fruit punch holds 2 gallons if 9 people share the entire pitcher equally how much punch does each person get
katrin2010 [14]
2×9= 18

18÷9= 2

Answer: 2 cups of fruit punch.

----------

Explanation: so, you divide. why do I know this? because it doesn't say "times," (multiplication word) "more than," (addition word) "less than/ left over." (subtraction word) so what your looking for is "equally," and "each."

So, can you do 2÷9? no, you cant. so you have to multiply 2×9 to get the answer. and what's the answer? 18!

so, now, can you divide 18÷9? yes!! why? because you can only divide big numbers like 18. and you can't divide small numbers like 2 or 9. do you get what I'm saying?

so, what's 18÷9? 2!!


I hope this helps! :) if you still don't understand it just please let me know :)

#72 help please asap.
ludmilkaskok [199]
Now CHECK by substituting into the angles in your question, 8(17-10)=56 and 90-34=56, so x=10 and y=17, and they each make up the angle of 56 degrees

Use the Quadratic Formula to solve the equation. (Enter your answers as a comma-separated list.) 13x^2 +1 = -10
12345 [234]

Step-by-step explanation:

The given quadratic equation is :

13x^2 +1 = -10x\\\\or\\\\13x^2+10x+1=0

The formula to solve a quadratic equation is :

x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}

Put a = 13, b = 10 and c = 1

So,

x=\dfrac{-10\pm \sqrt{10^2-4(13)(1)} }{2(13)}\\\\x=-0.118, -0.651

Hence, this is the required solution.
