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.

What is the area of the shaded region?
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

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:
Darryl has 2/3 of a bag of dog food. His dog eats 4/9 of a bag per week. How many weeks will the dog food last?
A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.
The number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.
What is a fraction?A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.
We have,
The amount of dog food in the bag = 2/3
The amount of dog food the dog eats per week = 4/9
We need to find the number of weeks that the dog finishes 2/3 of dog food.
The number of weeks:
1 week = 4/9 dog food
Multiply both sides by (9/4 x 2/3)
(9/4 x 2/3) x 1 week = (9/4 x 2/3) x 9/4 dog food
3/2 weeks = 2/3 dog food
[ 3/2 = 1 (1/2) ]
1(1/2) weeks = 2/3 dog food
This means in one and a half weeks the dog finished 2/3 of dog food.
Thus the number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.

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.

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 :)
