If 100c^2 has a value of 4950 what is the value of 100c98
N76 [4]

Answer:

100(49.5)^{49}

Step-by-step explanation:

Let's solve 100c^2=4950

Divide both sides by 100:

c^2=49.5

Take the square root of both sides:

c=\sqrt{49.5} (I did not keep the negative value because it doesn't matter since we are only considering even powers of c.)

So now let's plug it into:

100c^{98}

100(\sqrt{49.5})^{98}

100(49.5)^{49}

Si "m" es el lado mayor de un triángulo, dos cuyos ángulos interiores miden 30° y 60°, entonces el perímetro del triángulo es
lions [1.4K]

Answer:

perimetro = \dfrac{(3 + \sqrt{3})m}{2}

Step-by-step explanation:

triángulo 30°-60°-90°

1~:~\sqrt{3}~:~2

1m~:~m\sqrt{3}~:~2m

\dfrac{m}{2}~:~\dfrac{m\sqrt{3}}{2}~:~m

perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + m

perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + \dfrac{2m}{2}

perimetro = \dfrac{m + m\sqrt{3} + 2m}{2}

perimetro = \dfrac{3m + m\sqrt{3}}{2}

perimetro = \dfrac{(3 + \sqrt{3})m}{2}

Answer this math question pls I'm in a rush
777dan777 [17]

Answer:

61/18

Step-by-step explanation:

Make the mixed fraction an improper fraction first. So instead of 1 1/3, it'll be 4/3.

Now in a rectangular prism, there's two of each congruent sides (three pairs in total).

You'll need to multiply (4/3)(3/4) by 2 because there's two of them.

This gives you (1)(2) which equals 2.

Next, take another set --> (4/3)(1/3)(2) again because there's two of them.

This gives you (4/9)(2) which equals 8/9.

Last, take the last set --> (3/4)(1/3)(2)

This gives you (1/4)(2) which equals 1/2.

Now that you have all the areas of the rectangles, add them all together.

2+8/9+1/2 which equals 61/18 inches squared.
