Answer: 9sqrt(3)
Step-by-step explanation:
First, we can prime factorize 243.
243 = 3^5
Therefore we are computing the square root of 3^5
3^5 = 3^4 * 3^1; 3^4 = (3^2)^2
Therefore, sqrt(3^5) = sqrt((3^2)^2))*3^1)
= 3^2*sqrt(3)
= 9sqrt(3)

Answer:
B) 8
Step-by-step explanation:
Triangles MNC and RSC are similar because all 3 angles are the same, so the the ratio between each side should be the same.
If NC=12 and SC=6 then triangle MNC is scaled up by 2 from triangle RSC. This means each side of MNC is 2 times bigger than on RSC. So, sense RS=4, we can multiply that by 2 to get MN=8.
it takes me 12 minutes to run 2 kilometers. how long will it take me to run 10000 meters
Answer:
60 minutes
Step-By-Step Explanation:
1. 12/2= 6 (6 minutes per kilometer)
2. 10000/1000= 10 (10000m is 10km)
3. 10*6= 60min
If this helped, please consider picking this answer as the Brainliest Answer. Thank you!
Answer:
60 minutes or 1 hour
Step-by-step explanation:
Time taken to cover the distance of 2 km = 12 minutes
10000m = 10km
Then time taken to cover the distance of 10 km = 5 x 12 = 60 minutes
I have multiplied 12 with 5 because if we multiply 2km with 5 we will get 10km. So, hope you understood my explanation. If not ask me your doubt in comment.
how to do this equation y=2x-10 and 2y=x-8
Answer:
y=2x-10
2y=x-8
since the second equation equals 2y and the first is y that means the first equation times 2 equals the other one
4x-20=x-8
-x
3x-20=-8
+20
3x=12
x=4
then lets just plug it in
2y=4-8

2y=-4

Answer:
y = total amount of money in Maria’s savings account.
x= number of days.
you are given the y-intercept (12) and the slope of the equation ( $2/ 1day ).
thus, c = 12
m = 2
substitute these values into slope–intercept form,
y = mx + c
y = 2x + 12

Answer:
x=4 y=-3
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
x−2y=10 ; 6x+3y=15
Step: Solve x −2y= 10for x:
x − 2y + 2y = 10 + 2y (Add 2y to both sides)
x=2y+10
Step: Substitute 2y+10 forx in 6x+3y=15:
6x+3y=15
6x+3y=156(2y+10)+3y=15
15y+60=15 (Simplify both sides of the equation)
15y+60+−60=15+−60 (Add -60 to both sides)
15y=−45
15y/15=−45/15(Divide both sides by 15)
y=−3
Step: Substitute −3 for y inx=2y+10:
x=2y+10
x=(2)(−3)+10
x=4(Simplify both sides of the equation)
Answer:
x=4 and y=−3

In a right triangle ΔABC, the length of leg AC = 5 ft and the hypotenuse AB = 13 ft. Find:
The length of the angle bisector of angle A
Answer:
∠A is (5/3)√13
Step-by-step explanation:
The cosine of ∠A is [tex]\frac{AC}{AB}[/tex] = [tex]\frac{5}{13}[/tex]
The cosine of half of ∠A is given by the half-angle formula:
cos(A/2) = √((1 +cos(A))/2) = √((1 + 5/13)/2) = √(9/13) = 3/√13
The length of the segment b is found from ...
cos(A/2) = 5/b [adjacent side/hypotenuse]
∠ A = 5/cos(A/2) = 5/(3/√13)
∠ A = (5/3)√13
If Needed in decimal form : 6.01

What is the effect of removing the outlier 11 from the following data set? (1 point)
{11, 85, 87, 88, 91, 91, 92, 93, 95}
A The mean would increase.
B The median would decrease.
C The interquartile range would increase.
D The median of the lower quartile would stay the same.
Answer:
A The mean would increase.
Step-by-step explanation:
mean = sum of numbers ÷ how many numbers there are
the mean with the outlier 11:
(11 + 85 + 87 + 88 + 91 + 91 + 92 + 93 + 95) ÷ 9 = 81.4
the mean when removing the outlier 11:
(85 + 87 + 88 + 91 + 91 + 92 + 93 + 95) ÷ 8 = 90.25
the mean has now increased

For these kinds of problems, the point-slope formula comes in handy.
The point-slope form (y - y1 = m(x - x1) +b) uses the slope and a point given to find the y-intercept, or in this case, the equation of the line.
First, we plug the known #'s into the equation, then solve.
y - 7 = -7/3( x -0)
y - 7 = -7/3x
+7 +7
y = -7/3x +7
Therefore, the equation of the line is: y = -7/3x + 7

Tell whether the angels are adjacent or vertical. Then find the value of x.
(please show how you solved the problem!)
Answer:
Angles: adjacent
x = 18
Step-by-step explanation:
Adjacent Angles: angles that border each other to the left/right
Vertical Angles: opposite set of angles that are congruent
Given these definitions, these angles are not only adjacent, but also right angles. Right angles add to 90°.
Thus, 3x + 2x = 90Step 1: Combine like terms.
[tex]3x + 2x = 90[/tex] [tex]5x = 90[/tex]Step 2: Divide both sides by 5.
5x ÷ 5 = 90 ÷ 5x = 18Therefore, the answer is adjacent and x = 18.
Find the value of x, y, and z in the figure below:

Answer:
x=30°
y=15°

Step-by-step explanation:
2x+90+x=180°
2x=180°-90°
x=90/3
x=30
2y=x
y= 30/2
y=15°
2y°+z°=180°
