Answer:49

Step-by-step explanation:

sin22 = h/132

h = 132sin22 = 49

Answer:

The diameter is equal to twelve divided by 3.14." Divide the circumference by pi to get the answer. In this case, the diameter would be 3.82 inches.

Step-by-step explanation:

4 will be your answer

Explanation:

The factors of 12 are 1, 2, 3, 4, 6, 12

The factors of 88 are 1, 2, 4, 8, 11, 22, 44, 88.

So, as we can see, the Greatest Common Factor or Divisor is 4, because it is the greatest number that divides evenly into all of them.

Answer:

It simply means getting rid of the square root or radical in the denominator

Step-by-step explanation:

Rationalizing the denominator simply means getting rid of the square root or radical symbol in the denominator thereby making the denominator to be just a whole number.

For example if we want to rationalize the denominator in; 3/√2

We will multiply the numerator and the denominator by √2 to get rid of the radical in the denominator which is the square root sign.

Thus;

(3/√2) × (√2)/(√2)

This gives;

(3√2)2

Answer:

"To rationalize the denominator means to eliminate any radical expressions in the denominator such as square roots and cube roots." It is done usually by multiplying both numerator and denominator by the radical expression or another expression including the radical to be eliminated.

Step-by-step explanation:

Answer:

312.50

Step-by-step explanation:

8 , 20 , 50, 125 , 312.50

First term, a = 8

Second term, ar = 20

Find common ratio, r

Substitute a = 8 into second equation

ar = 20

8r = 20

r = 20/8

r = 2.5

Find the fifth term

ar⁴

= 8 * 2.5⁴

= 8 * 39.0625

= 312.50

Fifth term, ar⁴ = 312.50

Answer: A=2.25 and R=4.254

Answer:

Yes, they are.

Step-by-step explanation:

They are both obtuse triangles. They may be different sizes but they are the same.

Answer:

Vertex: (1/2, 16)

Zeros: t  =  − 1 /2, 3/2

Step-by-step explanation:

Step-by-step explanation:

As it is said that the triangles are similar so the ratio of the corresponding sides are equal so

AB / ED = BC / EF

x² / 18 = 7 / 14

x² / 18 = 1 / 2

2x² = 18

x² = 18 / 2

x² = 9

x² =( + 3)²

Therefore

x = 3 or x = - 3

Hope it will help :)❤

Answer:

  c  (all real numbers)

Step-by-step explanation:

The first inequality has the solution ...

  3 + v ≤ -4

  v ≤ -7 . . . . . . . subtract 3 from both sides

__

The second inequality has the solution ...

  -2v ≤ 14

  v ≥ -7 . . . . . . . divide by -2. Division by a negative reverses the inequality

__

So, the solution to the compound ...

  v ≤ -7  or  -7 ≤ v

is every number — all real numbers. The graph of that is the entire number line, as in choice C.
