What is the exact value of cot pi/3?​

Answer:

The answer is 4 3/10

Step-by-step explanation:

If you first break this question up into two steps, you first must add the whole numbers and then the fractions, like this:

2 7/10   1 6/10

First, add the whole numbers [Bold]

2 + 1

That equals the whole number 3

2 7/10    1 6/10

Next you add the fractions [Underlined]

7/10 + 6/10

this equals 13/10

Since this fraction is higher than 10/10, it equals a whole number too. This fraction, 13/10, will be simplified to 1 whole and 3/10. After simplifying this number you add the whole numbers once again resulting in 3 + 1, giving you 4. after finding this out you add your fractions back in, creating the answer of 4 3/10.

Hope this helps you out!

Step-by-step explanation:

9514 1404 393

Explanation:

The sine of an angle in standard position is the y-coordinate of the intersection of its terminal ray with the unit circle. When the angle is in the range 180° < θ < 360°, that point of intersection is in quadrant III or IV, where y-coordinates are negative.

That is where the sine curve is below the x-axis.

I'm assuming that if you don't need the variable solved, then you need it converted? here's another form.

Answer:

5/6 hour = 5/6 × 60 = 300/6 = 50 minutes

8 tasks in 50 minutes

1 task = 50/8 = 6 1/4 minutes

a. robot completes task in 6 1/4 minutes

b. #tasks per hour =

#of tasks × time takes to do task < or = 60

n × 6.25 = 60

6.25n = 60.

n= 60/6.25 = 9.6

robot can complete 9 tasks in one hour

By elimination method,

x+y=15

-x+y=5

------------

2y=20

i.e y=10

Now,

x+y=15

or, x+10=15

or, x=5

Answer:

I think the answer would be 40%

Step-by-step explanation:

U would do 16 divided by 4 and get 4 and a 0 then bam I have ur answe.

(₋4)²

how i got it -

1st i used the sum-product pattern

x² - 8x + 16

x² -4-4+16

then, found the common fact from the two pairs

x² - 4 - 4 + 16

(-4) - 4(-4)

rewrite in factored form

(x-4)-4(-4)

(-4) (-4)

combine to a square

(-4) (-4)

Answer:

x=4*

Step-by-step explanation:

*THIS IS ASSUMING THAT THIS EQUATION IS EQUAL TO ZERO

X^2-8x+16=0

Let's solve this equation by factoring. First, we need to find factors of 16 that add to -8. We find that those factors are -4 and -4. X^2 is simply x times x.

Therefore, when it is factored It should look like this:

(x-4)(x-4)=0

Now we take both factors and set them equal to zero:

x-4=0; x-4=0

In both of these equations we just need to add 4 to both sides.

x=4; x=4

x=4

Answer:

5x-5+3x+3+5x=180

Step-by-step explanation:

As it is a triangle, sum of all angles is 180.

5x-5+3x+3+5x=180

13x=182, x=14

The expression that represents the measure sum of the angle is

(5x – 5)° + (3x + 3)° +  (5x)° = 180°.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We also know that sum of all the interior angles of a triangle is 180°.

The given statement can be written as,

∠A + ∠B + ∠C  = 180°.

(5x – 5)° + (3x + 3)° +  (5x)° = 180°.

13x - 2° = 180°.

13x = 180° + 2°.

13x = 182°.

x = 14°.

We can also find the measure of each angle now by substituting the value of x in ∠A, ∠B, and ∠C.

Answer:

The midpoint (x,y)=(6,9)

Step-by-step explanation:

We need to find midpoints(x,y) of the line segment having endpoints S(8, 8) and T(4, 10)

The formula to find midpoint is:

[tex]Midpoint(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\[/tex]

We are given: [tex]x_1=8, y_1=8, x_2=4 , y_2=10[/tex]

Putting values and finding midpoint

[tex]Midpoint(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint(x,y)=(\frac{8+4}{2},\frac{8+10}{2})\\Midpoint(x,y)=(\frac{12}{2},\frac{18}{2})\\Midpoint(x,y)=(6,9)[/tex]
