Square root of 75 plus square root of 3
olya-2409 [2.1K]
Answer:
6√3

Explanation:
Before we begin, remember the following:
\sqrt{a*b} = \sqrt{a}  *  \sqrt{b}
m \sqrt{a} + n \sqrt{a}  = (m+n) \sqrt{a}

Now, for the given:
75 can be written as 25*3
This means that:
\sqrt{75} = \sqrt{25*3}
Applying the above concept, we can find that:
\sqrt{75} = \sqrt{25*3} = \sqrt{25}  *  \sqrt{3}
Now, we know that:
√25 = 5 (we ignored the negative value)

This means that:
√75 = 5√3

Finally, we can compute the needed sum as follows:
√75 + √3 = 5√3 + √3 = 6√3

Hope this helps :)

A spinner is half red and half blue. If you spin the spinner twice, what is the probability that you will get red both times?
Usimov [2.4K]

Answer:  Probability of getting red both times is \frac{1}{4}

Step-by-step explanation:

Since we have given that

A spinner is half red and half blue.

Probability of getting red is given by

\frac{1}{2}

Probability of getting blue is given by

\frac{1}{2}

Since he spins the spinner twice.

Probability that you will get red both times is given by

\frac{1}{2}\times \frac{1}{2}\\\\=\frac{1}{4}

Hence, Probability of getting red both times is \frac{1}{4}
