Answer: B. Two billion, eighty million :)

Answer:

The choice A.

Step-by-step explanation:

sin= Opposite/ hypotenuse

[tex] \sin(30) = \frac{ \sqrt{15} }{x} \\ \\ x = 2 \sqrt{15} [/tex]

tan = opposite/adjacent

[tex] \tan(30) = \frac{ \sqrt{15} }{y} \\ \\ y = 3 \sqrt{5} [/tex]

Answer: A spanning tree

Step-by-step explanation:

Answer:

m=3/2

Step-by-step explanation:

the line: y=mx+b

This line passes through the points

-> These points (x,y) are on the line

(-5/2,1) : x=-5/2  y=1

1=-5/2m+b                      

(-1/2,4) : x=-1/2    y=4

4=-1/2m+b

We have a system of equation:

1=-5/2m+b

4=-1/2m+b

After solving this, we have m=3/2   b=19/4

-> The slope is 3/2

We use the nCr combination formula because order doesn't matter.

The number of ways Kyle’s choose eight to attend his birthday party is 43263.

Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements. The number of combinations of n different things taken r at a time, denoted by nCr and it is given by, ⁿCr=n!/r!(n−r)!,where 0 ≤ r ≤ n.

Given that, there are 24 student in Kyle’s kindergarten class.

He choose eight to attend his birthday party

Now, number of ways is

²⁴C₈= 24!/8!(24-8)!

= 24×23×22×21×20×19×18×17×16!/8! 16!

= 24×23×22×21×20×19×18×17/8×7×6×5×4×3×2×1

= 3×23×11×3×4×19×3×17/4×3

= 3×23×11×3×19

= 43263

Therefore, the number of ways Kyle’s choose eight to attend his birthday party is 43263.

Explanation:

These angles are on alternating sides of the transversal line, and they are exterior of the parallel lines. Therefore, these are alternate exterior angles.

Alternate exterior angles are congruent when we have parallel lines like this.

Set the two expressions equal to each other. Solve for x.

3x-31 = x+59

3x-x = 59+31

2x = 90

x = 90/2

x = 45

Then we can find that:

Both alternate exterior angles are 104 degrees each, which confirms we have the correct x value.

Answer:

Step-by-step explanation:

let the width be w

p=l*w

1200= 200*w

1200= 200w

1200 = 200w

6 feet = w

width is 6 feet

let the length be a

p = l* w

1200 = a* 6

1200 = 6a

1200 = 6a

200 feet  = a

length is 200 feet

The equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)

From the question,

We are to determine which of the options is correct.

To determine which of the options is correct, we will evaluate the options one after the other.

8 dot 8 equals 8 Superscript 2 equals 16

That is,

8.8 = 8² = 16

Evaluating properly

8.8 = 8² = 8 × 8 = 64

Then, 8.8 = 8² ≠ 16

∴ This is NOT correct

9 dot 9 equals 2 left-parenthesis 9 right-parenthesis equals 18

That is,

9.9 = 2(9) = 18

Evaluating properly

9.9 = 9 × 9 = 9² = 81

Then, 9.9 ≠ 2(9) = 18

∴ This is NOT correct

10 dot 10 equals 2 left-parenthesis 10 right-parenthesis equals 100

That is,

10.10 = 2(10) = 100

Evaluating properly

10.10 = 10 × 10 = 10² = 100

Then, 10.10 ≠ 2(10) ≠ 100

∴This is NOT correct

11 dot 11 equals 11 Superscript 2 equals 121

That is,

11.11 = 11² = 121

Evaluating properly

11.11 = 11² = 11 × 11 = 121

Then, 11.11 = 11² = 121

This is correct.

Hence, the equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)
