Are the ratios 3:1 and 16:4 equivalent

Answers

First, simplify the 16:4 ratio.
• 16:4 ÷ 2 = 8:2 ÷ 2 = 4:1

Now, check to see if they're equivalent:
• 3:1 = 4:1 ???
- 3:1 =/= 4:1

So, NO these ratios are not equivalent.
No they are not equivalent 16:4 is like dividing by 4 which is 4:1

Suppose the lengths of the lengths of two strings are 10 centimeters and 17 centimeters. Describe how the lengths of these two strings compare.

Answers

-- The lengths of the two strings are not equal.
   They are different.

-- The 10-centimeter string is shorter than the 17-centimeter one.

-- The 17-centimeter string is longer than the 10-centimeter one.

(I'll bet you knew all of those things, but you were
afraid to say them because it's math and everybody
thinks that math is hard.  Am I right ?)
Let's just say that the string that is 10 cm long is string A and the string that is 17 cm long is string B. Because 10 < 17, string A is shorter than string B. Conversely, because 17 > 10, string B is longer than string A.

The total rainfall in forks , washington, october was 8 3/8 in. in september ,60% less rainfall fell in October how much rain fell in spetember in forks, washington?

express your awnswer in simplest form

Answers

Rainfall in October in Forks, Washington = 8 3/8 inches
                                                                 = 67/8 inches
Percentage of rainfall that has fallen less in September in Forks, Washington = 60%
Let us assume the amount of rainfall in September in Forks, Washington = x
Then
100x/60 = 67/8
10x/6 = 67/8
5x/3 = 67/8
5x * 8 = 67 * 3
40x = 201
x = 201/40
   = 5 1/40 inches
So the amount of rainfall in September in Washinton is 5 1/40 inches.

What's times what equals 116??

Answers

well, to find that out, you can simply just divide 116 by 2, and thats your answer!
116÷2= 58
~~~~~~~~
58·2=118

58 
~Hope this helped! :)
1x116=116
2x58=116
4x29=116.
Those are the only problems that equal 116.

Solve

x2 + 6x + 6 = 0

Answers

Answer:

The solution of x^2 + 6x + 6 is x = -1.2679 or -4.7320

Solution:

A two degree polynomial equation is given in the question.

We have been asked to solve it to find the value of ‘x’.

The given equation is:

x^(2)+6 x+6=0

There are two ways to solve this equation.

We can either factorise it or use the quadratic equation formula. For factorising it, it has to satisfy certain conditions.

The condition is b^2 - 4ac should be a perfect square otherwise the equation is not factorable.

a=1,b=6,c=6

On substituting the values of a,b and c, we get:

Which is not a perfect square.

Hence we have to use the quadratic equation is

x=\frac{-b \pm \sqrt{b^(2)-4 a c}}{2 a}

By substituting the values of a,b and in the quadratic equations. We get;

\begin{array}{l}{x=\frac{-6 \pm \sqrt{6^(2)-4 * 1 * 6}}{2 * 1}} \n\n {x=(-6 \pm √(12))/(2 * 1)}\end{array}

The two roots of x are:

\begin{aligned} x &=(-6-√(12))/(2 * 1) \n\n x &=(-6+√(12))/(2 * 1) \end{aligned}

On solving both the equations we will get the roots of the given equation, which are:

x = -1.2679 or -4.7320

Answer:

-1.2679 or -4.7320
