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.
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

A cube with a volume of 75 cm³ is dilated by a factor of 5. What is the volume of the dilated cube? Enter your answer in the box. Cm³.
Using the concept of dilation the volume of the dilated cube when dilated by a factor of 5 is 9375 cm³.
What is dilation?Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Given
A cube with a volume of 75 cm³ is dilated by a factor of 5.
The edge of the cube before dilation
Edge³ = 75
Edge = 4.217
The edge after dilation will be
Edge = 5 x 4.217
Edge = 21.08
The volume of the dilate cube will be
Volume = ( Dilated Edge)³
Volume = 9375
The volume of the dilated cube is 9375 cm³.

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.

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

A spinner is divided into 12 identical sectors and labeled 1 through 12. How many spins are expected for a multiple of 5 to be spun 22 times? Select from the drop-down menu to correctly complete the sentence. The spinner is expected to have to spin approximately Choose... times for a multiple of 5 to be spun 22 times
1. 68
2. 88
3. 110
4. 132
Using the binomial distribution, it is found that the spinner is expected to have to spin approximately 132 times for a multiple of 5 to be spun 22 times, hence option 4 is correct.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected number of trials until q successes is:
[tex]E_f(X) = \frac{q}{p}[/tex]
In this problem:
We want 22 successes, hence q = 22.2 out of 12 sections(5 and 10) are multiples of 5, hence p = 1/6.Then:
[tex]E_f(X) = \frac{q}{p} = \frac{22}{\frac{1}{6}} = 22 \times 6 = 132[/tex]
Hence option 4 is correct.

Write an equation the describes the line passing through point (0,7) with slope - 7/3
Answer:
[tex]y=\frac{7}{3}x+7[/tex]
Step-by-step explanation:
[tex]y=mx+b\\\\y=\frac{7}{3}x+b\\ \\7=\frac{7}{3}(0)+b\\ \\7=b\\\\y=\frac{7}{3}x+7[/tex]
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

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
