Answer:

Answer C: y=3x+2 because the y-intercept is positive 2 if you graph it

Answer:

x = 4 sqrt(3)

Step-by-step explanation:

x is not to be confused by the mark on the right angle -- X

The function is the cosine of Y which is 30 degrees.

The cosine of 30o is sqrt(3)/2

cos(30) = adjacent side / hypotenuse = sqrt(3) / 2

The adjacent side is 6

cos(30) = 6/ x = sqrt(3) / 2

6/x = sqrt(3) / 2                      Cross multiply

x * sqrt(3) = 6 * 2

x * sqrt(3)  = 12                       divide by sqrt(3)

x = 12 / sqrt(3)                        Multiply top and bottom by sqrt(3)

x = 12* sqrt(3) / sqrt(3) * sqrt(3)

x = 12 sqrt(3)/ 3                      Divide by 3

x = 4 sqrt(3)

Step-by-step explanation:

The average color of the population would become paler would living in White Sands National Monument for a few generations change a population of eastern fence lizards. Hence, option C is correct.

It's difficult to travel to White Sands National Park, and there aren't many things around to keep you very busy. It's a peaceful area with peculiar traits and uncommon lifeforms. Not everyone can benefit from it, but some of us can. If you go, sand will likely go in your eyes as well as your boots.

Plan to spend a whole day in White Sands National Park for the finest experience. Early in the morning, before the tourists gather and the warmth rises, hike the Alkali Flat Trail. Have a picnic lunch and go sledding on the dunes around noon. One of the shorter hiking trails is another option.

Thus, option C is correct.

The distance formula is:

D = sqrt((x2-x1)^2 + (y2-y1)^2)

D= sqrt ((6-2)^2 + (8-1)^2)

D = sqrt(4^2 + 7^2)

D = sqrt( 16 + 49)

D = sqrt(65)

D = 8.06

Rounded to the beat tenth = 8.1 units.

The answer is C. 8.1 units

Answer:

C

Step-by-step explanation:

S has coordinates (2 , 1) and U has coordinates (6, 8) . Computing the SU vector gives us (4 , 7)

taking the distance formula : sqrt(4^2 +7^2)

Answer:

20 gray squares

Step-by-step explanation:

Given

See attachment for squares

Required

Number of gray squares when white = 16

First, we calculate the equation that represents both squares.

The white squares

[tex]a = 2[/tex] --- initial

[tex]d = 4 - 2 = 6 - 4[/tex]

[tex]d = 2[/tex] -- difference between successive gray squares

So, the nth term is:

[tex]W_n = a + (n - 1)d[/tex]

[tex]W_n = 2 + (n - 1)*2[/tex]

[tex]W_n = 2 + 2n - 2[/tex]

[tex]W_n = 2n[/tex]

The gray squares

[tex]a = 6[/tex] --- initial

[tex]d = 8-6=10-8[/tex]

[tex]d = 2[/tex] -- difference between successive gray squares

So, the nth term is:

[tex]G_n = a + (n - 1)d[/tex]

[tex]G_n = 6 + (n - 1) *2[/tex]

[tex]G_n = 6 + 2n - 2[/tex]

[tex]G_n = 4 + 2n[/tex]

When the white squares is 16

[tex]W_n = 16[/tex] --- Calculate n

[tex]W_n = 2n[/tex]

[tex]16 = 2n[/tex]

[tex]8 = n[/tex]

[tex]n = 8[/tex]

To get the number of gray squares;

Substitute [tex]n = 8[/tex] in [tex]G_n = 4 + 2n[/tex]

[tex]G_n = 4 + 2 * 8[/tex]

[tex]G_n = 20[/tex]

Complete question:

The measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle. The measure of the third angle is  11 more than the measure of the smallest angle. Find all three measures .

Let the smallest angle be x

Let the largest angle be y

Let the third angle be z

Since the sum of angle in the triangle is 180, then x+y+z = 180 .. 1

If the measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle, this is expressed as;

x = y - 34

y = x + 34 ..... 2

If the measure of the third angle is  11 more than the measure of the smallest angle, this is expressed as;

z = x +  11 .... 3

Substitute 2 and 3 into 1;

x + (x+34) + (x+11) = 180

x+x+x+45 = 180

3x+45 = 180

3x = 180 - 45

3x = 135

x = 135/3

x = 45 degrees

From 2;

y = x+34

y = 45 + 34

y =79degrees

From3;

z = x+11

z = 45 + 11

z = 56degrees

Hence the measure of the angles are 45degrees, 79egrees and 56degrees

Step-by-step explanation:

You take the number of student in 8th grade that are on social media for more than an hour which gives you (12) and divide it by the total number of students (81).

12/81=0.148 repeating

You then round 0.148 repeating to 0.15 and then turn it into a percent by moving the decimal two places to the right.

Answer:

11°

Step-by-step explanation:

This is hard to explain because they don't have names lol

So looking at the larger main triangle...

the top angle is composed of two angles measuring 40° and 41°. So it is equal to 81°.

The angle on the lower left side is a supplimentary angle with the one that measures 110°. The two of them combined make a line. A straight line is 180°, so that angle is 70°. (180 - 110)

The final angle in the triangle is accross from x. This makes them a pair of vertical angles, so therefore congruent.

The angles of a triangle add up to 180°

We already know the other two angles so 180 - 81 - 70 = 11°

so x is also 11°
