How do you do this problem 1/4 +4x/5=11/20?

Nutka1998 [239]

$\frac{1}{4}+\frac{4}{5}x=\frac{11}{20}\\\\\frac{4}{5}x=\frac{11}{20}-\frac{1}{4}\\\\\frac{4}{5}x=\frac{11}{20}-\frac{5}{20}\\\\\frac{4}{5}x=\frac{6}{20}\ \ \ \ \ \ \ |\cdot\frac{5}{4}\\\\x=\frac{30}{80}=\frac{3}{8}$

what is the probability of rolling 6 five times in a row? Write your answer as a fraction in simplest form.

qaws [65]

Answer:

1/7776.

Step-by-step explanation:

The probability of rolling a six in 1 throw = 1/6.

Rolling a 6 5 times in a row = (1/6)^5

= 1/7776.

The probability is multiplied because each roll is independent from other rolls.

Looking for right triangle side a is 1 inch long,and side b is 2 inches long. What is the length of side c?

Sergeeva-Olga [200]

Answer:

$\sqrt{5}$

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

In this situation a = 1, b = 2

$1^{2} + 2^{2} = c^{2}$

1 + 4 = $c^{2}$

5 = $c^{2}$

c = $\sqrt{5}$

This is an important mathematical theorem to know. It's called the Pythagorean Theorem.
