[tex]\sqrt{6} +\sqrt{6} =2\sqrt{6}[/tex]

Answer:

6

Step-by-step explanation:

To find the median you simply look for the number in the middle of the list.

In this particular case 1 and 11 are both the fifth number in the series of numbers. When this happens you have to add the two terms together (1+11) and divide by two       (12/2)=6

Answer:

it's an equilateral triangle, so all the angles will be equivalent.

2x + 2x + 2x = 180

6x = 180

x = 30°

Answer:

30

Step-by-step explanation:

So, the solve this, lets first find the type of traingle it is.

Well, all the sides are equal, beign 3, so it must be a equalaterial triangle.

This means both the sides and angles will be the same.

Remember, there are 180 degrees in a triangle.

So we can think of it like this, since there are 3 angles, each being 2x:

6x=180 degrees

Now we can just get x alone by divide by 6:

x=30

So your answer is 30!

I hope this helps! :)

the following could define the function g: 20. (2.5)ˣ = g(x)

correct option: B

Exactly one element of Y is assigned to each element of X in a mathematical function from a set X to a set Y. Both the set X and the set Y are referred to as the function's domain and co-domain, respectively. The basic conception of functions was the relationship between fluctuating quantities and other variables.

h(x) = 20. 4ˣ    (0, 20)

here, g(x) passes through the point (0, 20)

thus, g(x) = 20. aˣ

when x > 0, f(x) < g(x) < h(x)

hence a < 4

so, 20. (2.5)ˣ - 10. 2ˣ > 0

or, 20. (2.5)ˣ = g(x)

correct option: B

Answer:

Step-by-step explanation:

h and p are the number of history and psych textbooks, respectively.

store sold a total of 411 textbooks in a week.

h + p = 411

The number of history textbooks sold was 69 less than the number of psychology textbooks sold.

h = p - 69

Substitution

(p-69) + p = 411

2p = 411+69

p = 240

h = p-69 = 171

171 history books and 250 psych books

Answer:

[tex]y=10x\text{ or }y=10x+0[/tex]

Step-by-step explanation:

Slope-intercept form is given by [tex]y=mx+b[/tex].

Since Farmer Coraz purchases 10 items every month, he will have [tex]10\cdot x[/tex] items every [tex]x[/tex] months. Since he initially starts out with 0 items, at [tex]x=0[/tex], y is also equal to 0, and thus we have the final equation:

[tex]y=10x\text{ or }y=10x+0[/tex]

*Note: while slope-intercept form is [tex]y=mx+b[/tex], since the value of [tex]b[/tex] is 0, it is possible to omit it from the final equation and both answers should receive credit.

The ∠1+∠4=180 degree is always true, ∠5-∠7=0 is always true , z⊥y is sometimes true, ∠2≅∠8 is always true and ∠2-∠3=∠1-∠4 be sometimes true.

Arrangement of reference lines or curves used to identify the location of points in space is called coordinate system.

Line x is parallel to line y.

Line z intersects lines x and y.

∠1+∠4=180 degree is always true.

∠5-∠7=0 is always true because the two angles are true.

z⊥y is sometimes true.

∠2≅∠8 is always true because the two angles are congruent.

∠2-∠3=∠1-∠4 will be sometimes true.

Hence, the ∠1+∠4=180 degree is always true, ∠5-∠7=0 is always true , z⊥y is sometimes true, ∠2≅∠8 is always true and ∠2-∠3=∠1-∠4 be sometimes true.

Step-by-step explanation:

Answer:He works 40 hours each week at a rate of $16 per hour.

Step-by-step explanation:

Answer:

the vertex is (-7, -63)

Step-by-step explanation:

x^2 + 14x - y - 14 = 0

x^2 + 14x = y + 14 (to isolate the x)

x^2 + 14x + 49 = y + 14 + 49

(x+7)^2 = y + 63

now we convert to vertex form, which is y = a(x – h)2 + k :

(x+7)^2 = y + 63

y = (x+7)^2 - 63

The vertex in vertex form is shown as (h, k) from y = a(x – h)2 + k, so in this case, h = -7 and k = -63. H is the x-coordinate as shown while k is the y-coordinate. Thus, the vertex is (-7, -63)

The perimeter of the square of side 5 cm  is 20 cm

The perimeter of a square is calculated with the formula:

Perimeter = 4 * length of side

length of the side = 5 cm

Perimeter = 4 * 5 cm

Perimeter = 20 cm

Therefore, the perimeter of the square is 20 cm

By definition of perimeter, the correct answer is option C. the perimeter of the square is 20 cm.

The perimeter of a two-dimensional figure is the distance around the figure. That is, the perimeter of a flat geometric figure is called the length of its contour.

So, the perimeter is the measurement obtained as a result of the sum of the sides of a flat geometric figure. So to calculate the perimeter of a figure it is necessary to know two basic variables:

A square is a flat geometric figure that has four equal sides, so the expression to calculate the perimeter of a square is:

Perimeter= 4× length of the sides

In this case, a square has a side length of 5 cm. So, the perimeter of the square is calculated as:

Perimeter= 4× 5 cm

Solving:

Perimeter= 20 cm

Finally, the correct answer is option C. the perimeter of the square is 20 cm.
