Which of the the following could be the ratio between the lengths of the two legs of a 30-60-90?Check all that apply. (A)Sqrt2:Sqrt3 (B)1:Sqrt2 (c)Sqrt2:Sqrt2 (D)2Sqrt3:Sqrt6 (E)1:Sqrt3 (F)Sqrt3:Sqrt3

Answers

Answer 1

Answer: This is worth remembering:

In a 30-60-right triangle,
-- the side opposite the 30 is 1/2 the hypotenuse
-- the side opposite the 60 is (1/2 the hypotenuse) times (square root of 3).

====================================

I believe Choice-'E' is the only one you could make with the above rule.

Answer 2

Answer: $(a)/(a √(3) ) = (1)/( √(3) ) \ \ \ \Rightarrow\ \ \ Ans.\ E\n\n(2a)/(a √(3) ) = (2)/( √(3) )=(2\cdot √(2) )/( √(3)\cdot √(2) )=(2 √(2) )/( √(6) ) \neq (2 √(3) )/( √(6) ) \n\n (a)/(2a ) = (1)/( 2 )$

What is the common difference between successive terms in the sequence?0.36, 0.26, 0.16, 0.06, –0.04, –0.14,

Answers

the common difference between successive terms

To find the common difference we subtract the first term from second term

0.36, 0.26, 0.16, 0.06, –0.04, –0.14,

0.26 - 0.36 = -0.10

0.16 - 0.26 = -0.10

0.06 - 0.16 = -0.10

-0.04 - 0.06 = -0.10

-0.14 - (-0.04) = -0.10

We can see that the common difference is =0.10

the common difference between successive terms = -0.10

The correct answer is:

-0.10.

Explanation:

The common difference between successive terms in a sequence is the number you add to each term to find the next one.

To find this number, you can subtract the first term from the second, the second from the third, and so on:

0.26-0.36 = -0.10

0.16-0.26 = -0.10

0.06-0.16 = -0.10

-0.04-0.06 = -0.10

-0.14--0.04 = -0.10

The common difference is -0.10.

It is not always helpful to rewrite an equation in standard form as a first step in solving it.True/False?

Answers

The answer to the problem above is True. Standard form of an equation means the right side of the equation should be 0, and everything on the left side. For example, x^2 = 4 , to make this this in standard form you have to transfer number 4 to the left side of the equation making it x^2 - 4 = 0.
In this situation, if you will be asked to look for x, there is no need to make the equation in standard form, you can directly take the square root of both sides of the equation to get x.

Answer:

True

Andy is one-fourth as old as his grandfather, who is 76 years old. Write an equation to determine whether Andy is 19 or 22 years old.

Answers

We know that if we multiply Andy's age by four we obtain 76. Lets assume that Andy's age its x. so
4*x=76
Now we have to solve equation
4*x=76 /:4 divide both sides by 4
x=19 - its the answer

A=Andy
G=Andy's Grandfather

A*4=G
G=76
A*4=76
/4
a=19
