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

13 km
22 km
square kilometers
Step-by-step explanation:
Area of the triangle is
= 1 /2 * base * height
= 1 /2 * 22 * 13
= 143 square kilometers
Hope it will help :)❤
Answer:
58.5
Step-by-step explanation:
( (22 * 13) / 2 ) - ( (13 * 13) / 2 ) = ( 286 / 2 ) - ( 169 / 2 ) = 143 - 84.5 = 58.5

1) not tangent
2) tangent
3) not tangent
Step-by-step explanation:
If they are tangent, the triangles formed will be right triangles.
Check using the Pythagorean theorem:
1) 18² = 14.4² + 11.7²
324 = 207.36 + 136.89
324 ≠344.25 not tangent
2) 7.5² = 4.5² + 6²
56.25 = 20.25 + 36
56.25 = 56.25 tangent
3) 20² = 12² + 12²
400 = 144 + 144
400 ≠ 288 not tangent

Sophie can type 128 words in three minutes how many minutes will it take her to type 576 words?
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.

What is an equation of the line that passes through the points (-4, 8) and
(2, -1)?
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 :)
Data from a representative sample were used to estimate that 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. You decide to conduct a survey to estimate this proportion for the current year. What is the required sample size if you want to estimate this proportion with a margin of error of 0.05
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:
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]

What is the surface area of this triangular pyramid?
___square inches
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
Give triangle ABC with coordinates A(3, 8), B(9,0) and C(5,2). How can you prove that triangle ABC is isosceles? Show your work.
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
√
52
and therefore isosceles.Step-by-step explanation:

-6
-4
ООО

о в
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.

Two sides of a right triangle are 8 and 12. Find the missing side of 8 and 12 are a leg and a hypotenuse.
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.
