Answer 1
Answer:

Answer:

Step-by-step explanation:

so the area of a circle is A=\pi r^(2)

111.6=3.14*r^(2) divide by 3.14 on both sides. that makes 36=r^(2) take the square root of both sides. r=6.  

now we find the diameter. 2\pi r=2*3.14*6=3.14*12 which is approximately 38.68

Find the length of side xx in simplest radical form with a rational denominator.

Answers

The length of side is √10/2

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given triangle is a 45-90-45 so if the sides are x then the hypotenuse will be x√2

From the figure the hypotenuse of triangle is √5

SO equation it to x√2

We get √5=x√2

Divide both sides by √2

√5/√2=x

As the denominator should be a whole number we have to rationalize the denominator.

Multiply numerator and denominator with √2

√5/√2×√√2/√2

√10/2

Hence, the length of side is √10/2

Answer:

(√(10) )/(2)

Step-by-step explanation:

on a 45 - 45 - 90 triangle if the sides are x then the hypotenuse is x√(2)

so,

√(5) = x√(2)                  (Divide by √(2) )

(√(5) )/(√(2) ) = x                        (rationalize the denominator)

(√(5) )/(√(2) ) · (√(2) )/(√(2) ) = (√(10) )/(√(4) ) = (√(10) )/(2)

Three hundred high school seniors were surveyed about their intended college majors. The results are displayed in the Venn Diagram below.If a student is randomly selected from the group, what is the probability that they are majoring in both math and science? Round your answer to the nearest whole percent.

A) 10%
B) 17%
C) 33%
D) 40%

Answers

The sample space of the problem is 300 while the U' is equal to 100 as given. The given diagram also shows A and B separately so we can determine the part where the two coincides. The equation goes 
120 + 50 + x + 100 = 300x = 30
Hence the probability is 30/ 300 or 10%
