Let's solve for the other leg length
a^2 + 21^2 = 42^2
a^2 + 441 = 1764
subtract 441 from both sides
a^2 = 1323
take the square root of both sides
a = sqrt.(1323)
a = 21 sqrt.(3)

The correct answer is C.) The length of the remaining leg is 21 sqrt.(3).

Hope this helps

¹¹/48 of the full cup

Step-by-step explanation:

We add the two fraction first to determine the total ratio

¹/4 + ²/3 = ¹¹/12

She uses ¼ cup grape juice for ¹¹/12 cup full of diluted grape juice

Therefore;

¼ : ¹¹/12

How How much grape juice does Sarah use for each full cup of water, i.e ¹²/12

? (x) : ¹²/12

We cross multiply the ratios;

¹²/12 * ¼ = ¹¹/12 * x

³/12 = ¹¹/12 x

³/12 * ¹²/11 = x

¹¹/48 = x

Consider the following system of equations:
Delicious77 [7]

Answer:

The system has infinitely solutions

Step-by-step explanation:

we have

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

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

Multiply by 3 both sides

x^{2}+y^{2}=\frac{5}{2} ----> equation A

The equation A is a circle centered at origin with radius r=\sqrt{5/2}\ units

and

5y^{2} =\frac{25}{2}-5x^{2}

5x^{2}+5y^{2} =\frac{25}{2}

Divide by 5 both sides

x^{2}+y^{2} =\frac{5}{2} ----> equation B

The equation B is a circle centered at origin with radius r=\sqrt{5/2}\ units

Equation A and Equation B are the same

Therefore

The system has infinitely solutions

4th grade math. Help?!
viva [34]

Answer: Well... does it give you the approximate length or actual length of the butterfly? If so, you would take that length and multiply it by 5. That would give you the length of the 5 butterfly lined up together.

If it does not give you the approximate length or actual length, look up the length on google.  (Google Answer- Size: 2.5" - 4.0" range.)

Take that and multiply it by five to get the length of the 5 butterflies.
