Answer:

A. Transform Boundary

Step-by-step explanation:

Transform boundaries are places where plates slide sideways past each other

Divergent Boundaries occur  when two tectonic plates move away from each other

Convergent Boundaries are when both the plates collide into each other

Subduction boundaries are when one plate bends and slides underneath the other curving down into the mantle

Answer:

Kayla,  learn this,  :D  more math is based on it.  Just learn it, just memorize the following

Step-by-step explanation:

m = slope

m = rise / run

m = y2 - y1   /  x2 - x1       ( this is still rise over run but in point form )

they give us two points to plug into the above formula

P1 = (-4, 8 )  in the form of ( x1, y 1 )

P2 = (2, -1)  in the form of (x2, y2 )

now plug those into the above formula

m = ( -1 - 8 ) / ( 2-(-4) )

m = -9  /  ( 2 + 4 )

m = -9 / 6

m = - 3/2

since we know the slope now  , we can use the point slope equation of

y - y1 = m ( x - x1)

use the m we found and either point  , P1 or P2

y - 8 = -3/2(x -(-4) )

y-8 = -3/2(x + 4)

y-8 = -3/2x - 6

y = -3/2x -6 + 8

y = -3/2x + 2

there you go  :)

Answer:

370 million

Step-by-step explanation:

In the 10 years from 2000 to 2010, the population was multiplied by the factor ...

100% + 9.6% = 109.6% = 1.096

In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:

2030 population = (308 million)·(1.096²) ≈ 370 million

Answer:

150

Step-by-step explanation:

100%/ x% = 219/ 416

Cross multiply

x = 150 %

219 is 150% of 416

Answer:

8.94 if no rounding is necessary.

Step-by-step explanation:

Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...

8² + b² = 12²

64 + b² = 144

Subtract 64 from both sides...

64 - 64 + b² = 144 - 64

b² = 80

[tex]\sqrt{80}[/tex] = 8.94 if you're not rounding.

Answer:

X1 = 34

X2 = -42

Step-by-step explanation:

Given the simultaneous equations

X1 + X2 =-8 .... 1 * 3

3X1 +2X2 = 18​ .... 2 * 1

______________________

3X1 + 3X2 = -24

3X1 +2X2 = 18​

Subtract

3X2 - 2X2 =-24 - 18

X2 = -42

Substitute X2 = -42 into 1

X1 + X2 = -8

X1 - 42 = -8

X1 = -8+42

X1 = 34

Hence the solution to the system of equation is (34, -42)

Answer:

22/7 - irrational number

1.141141114 - irrational number

17/4 - rational number

-6 - integer

[tex]\frac{\pi }{2}[/tex] - irrational number

0 - whole number

9 - natural number and whole number

21/3 - natural number and whole number

Step-by-step explanation:

natural numbers would be numbers 1,2,3,4,5,6,7...

whole numbers would be numbers 0,1,2,3,4,5,6...

integers are negative whole numbers

rational numbers are fractions and numbers that have decimal points

irrational numbers are number such as [tex]\pi[/tex] or [tex]\sqrt{5}[/tex]

Answer:

28.29 inch.

Step-by-step explanation:

So diameter is 9.

Circumference = pi x d

= 22/7 x 9

=28.29inch.

Answer:

The required sample size is 329.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money.

This means that [tex]\pi = 0.31[/tex]

Confidence level is not given, so we assume 95%.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

What is the required sample size if you want to estimate this proportion with a margin of error of 0.05?

We need a sample size of n. n is found when M = 0.05. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.05 = 1.96\sqrt{\frac{0.31*0.69}{n}}[/tex]

[tex]0.05\sqrt{n} = 1.96\sqrt{0.31*0.69}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.31*0.69}}{0.05}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.31*0.69}}{0.05})^2[/tex]

[tex]n = 328.6[/tex]

Rounding up

The required sample size is 329.

Answer:

13 minutes and 30 seconds

Step-by-step explanation:

Okay so first you would divide 128 by 576. But since it takes her 3 minutes just to type 128 words you have to multiply 4.5 times 3. It will take her 13.5 minutes to type 576 words or 13 minutes and 30 seconds.

Step-by-step explanation:

hope this helps

Let be a1 = 8 and a2 = 8 [ From question ]

We have to find out common differences which denoted by letter d .

d = a2 - a1 [ Formula ]

= 8 - 2

= 6

Thus,the common difference between successive terms in the sequence is 6 .

Answer:

6.

Step-by-step explanation:

We have to find out common differences which denoted by letter d .

d = a2 - a1 [ Formula ]

= 8 - 2

= 6

Also,

2+6=8 +6=14 +6=20 +6=26

So, It's Added Up By 6.

Answer:

The distances AB and BC are

√

52

and therefore isosceles.

Explanation:

If we label them A(13,-2) B(9-8) and C(5-2)

The distance between A and B:13⇒9=4−2⇒−8=42+62=52 so the distance is √52

The distance between B and c:9⇒5=4−8⇒−2=642+62=52

the distance is

√

52

The distance between A and C is 8 as they are both on -2 for

y

The distances AB and BC are

and therefore isosceles.Step-by-step explanation:

Answer:

Surface area = 10.7 in.²

Step-by-step explanation:

Surface Area of triangular pyramid = BA + P*L

Base Area (BA) = ½*nh

b = 2 in.

h = 1.7 in.

BA = ½*2*1.7 = 1.7 in.²

Perimeter (P) = 2 + 2 + 2 = 6 in.

Slant height (L) = 3 in.

Plug in the values

Surface Area = 1.7 + ½*6*3

Surface area = 10.7 in.²
