Answer:

B

Step-by-step explanation:

Rationalize the denominator. That means you multiply √10 on both the numerator and denominator of the question.

\dfrac{5}{\sqrt{10} } * \dfrac{ \sqrt{10} }{\sqrt{10} }

The result is

\dfrac{5 \sqrt{10} }{10}

Notice that the 5 in the numerator, partially cancels out with the 10 in the denominator.

The answer is \dfrac{ \sqrt{10} }{2}

nordsb [41]

Answer: It takes Him 1/4 hours to decorate both signs,

Step-by-step explanation:

Hi, since the area of a rectangle is equal to:

Area: length x width

Replacing with the values given;

Sign 1 =A1 = 2/3 x 1/4 =1/6 ft2

Sign 2 =A2= 1/2 x 1/3 = 1/6 ft2

If we sum both areas:

A1 +A2 = 1/6 + 1/6 = 2/6 ft2 = 1/3 ft2 (total area)

Since it takes Roberto 3/4 hour to decorate a 1-square-foot sign:

For 1/3 ft2

3/4 hour x 1/3 ft2 = 1/4 h

ITt takes Him 1/4 hours to decorate both signs,
