HELPPP!! Which Of The Following Could Be The Ratio Between The Lengths Of Two Legs Of A 30,60,90 Trianglecheck

Answers

Answer 1

Answer:

[tex]\sqrt{3}:3\\1:\sqrt{3}[/tex]

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

The tangent ratio is defined as:

[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

The cotangent ratio is defined as:

[tex]\displaystyle \cot\theta=\frac{\text{adjacent leg}}{\text{opposite leg}}[/tex]

As shown above, the tangent and the cotangent are the ratios of the two legs in any possible order.

If the triangle has angles of 30°, 60°, and 90°, then we can take one of the acute angles and find the tangent and cotangent to know the required ratios:

Let's take for example the 30° angle:

[tex]\displaystyle \text{ratio of legs: }\tan 30^\circ=\frac{\sqrt{3}}{3}[/tex]

[tex]\displaystyle \text{ratio of legs: }\cot 30^\circ=\sqrt{3}[/tex]

Thus the possible ratios from the list are:

[tex]\sqrt{3}:3\\1:\sqrt{3}[/tex]

The reciprocals of those ratios are also applicable

If the system of equations is 2 linear equations in 2 variables, the system has no solutions
If the system of equations is 3 linear equations in 3 variables, the system has no solutions

Answers

Answer:

If I get 2=3 in solving the system, it means the following:

If the system of equations is 2 linear equations in 2 variables, the system has no solutions If the system of equations is 3 linear equations in 3 variables, the system has no solutions

Step-by-step explanation:

The solution of linear system of equations implies that a point has to be found that holds true on all equations involved.

The system may consist of two equations involving two unknowns or may consist of three equation with three unknowns.

When a system of equation has no solution, the variables are removed in solving the equations and we get an equation or values in the form.

constant = constant

So,

If I get 2=3 in solving the system, it means the following:

If the system of equations is 2 linear equations in 2 variables, the system has no solutions If the system of equations is 3 linear equations in 3 variables, the system has no solutions

In a game, players have 60 seconds to toss rings into boxes.

Rings that land in green boxes, g, earn 5 points
Rings that land in blue boxes, b, earn 10 points
Players must earn at least 50 points to win
Which inequality models the combination of tosses needed to win?

Answers

Answer: g*5 + b*10 ≥ 50.

Step-by-step explanation:

Let's define g = number of rings that land in green boxes.

and b = number of rings that land in blue boxes.

For each ring in the green box you earn 5 points, then if there are g rings in the green box, you have g*5 points.

And for the blue is similar, if there are b rings in the blue box, you will have b*10 points.

Then the total number of points that you will get is:

T = g*5 + b*10.

And the minimum that you need to win is 50 points, the inequality will be:

T ≥ 50

or

g*5 + b*10 ≥ 50.

Answers

The interest is %2 of 520 which, if you do the math, is 10.4 cents. You want to find out how much interest it is for 6 years so you have to multiply them.

10.4 x 6 = 62.4

Express 4/10 as a decimal number, and identify another decimal number that is equal to it. 4/10 expressed as a decimal number is ___, which is equal to ___

Answers

Answer:

Step-by-step explanation:

Decimal number in mathematics is one in which the whole number and the fractional part is separated by a decimal point

If we divide 4 by 10 it will give us a a decimal number which was done below

4/10

=0.4

And also if we divide 40 by 100 we will still have a decimal of 0.4

0.4=40/100

Express 4/10 as a decimal number, and identify another decimal number that is equal to it. 4/10 expressed as a decimal number is 0.4 which is equal to _40/100__

16x - 4y = 18
x = -6y - 7​

Answers

When you use the substitution method you need to plug a value into the corresponding variable of another equation.

In this occasion,"-6y-7" can be plugged into the x of "16x-4y=18" because it represents the x.

16(-6y-7)-4y=18

Distribute 16 into the parentheses

-96y-112-4y=18

Combine like terms

-96y-4y-112+112=18+112

-100y=130

Divide by -100 to get y by itself

y=-1.3 or -13/10

Now plug the y into any equation...I chose "x = -6y - 7​" but it doesn't matter

x= -6(-1.3)-7

x=-14.8 or 4/5

The constant of proportionality for the ratio of cubs to female bears is 3.

The constant of proportionality is typically used when we are comparing something with another thing.

In this case, since every female bear has 3 baby cubs, the constant of proportionality for the ratio of cubs to female bears will be:

= 3/1

= 3

In conclusion, the correct option is 3.

Answer:  -5x^3 -13x^2 -6x + 15ix + 39ix + 18i

Step-by-step explanation:

An equation with zeros at these numbers could be put in form x = number.

So, (x-3) could be set to 0 to get x=3.

So, you can look at these "answers" they give you and work backward to get:

(x-3)(x+2/5)(x-3i)

Multiply first two together.

x^2+2/5x-3x-6/5

simplify

x^2 - 2 3/5x -6/5

Change first term to have same denominator by multiplying by "1" in the form of -5/-5

-5x^2/-5 - 13/5x -6/5

Divide all terms by 1/5 (which is the same as multiplying each term by 5)

(-5x^2 -13x -6)

Now multiply by (x-3i)

-5x^3 -13x^2 -6x + 15ix + 39ix + 18i
