<h3>Answer: C) 36</h3>

=========================================

Explanation:

Check out the attached image below. Basically I drew out the given diagram and then I added the variables a,b,c,d,e,f,g. Those variables represent the side lengths of the 7 squares. Each square has a perimeter of 4*s where s is the side length, but we dont consider the side that is running along the dashed line (that connects P directly to Q). So we have 3 sides per square added up.

The first square has us travel a distance of 3*a, then the second square a distance of 3*b and so on. Overall, the total distance traveled is

3a+3b+3c+3d+3e+3f+3g = 3(a+b+c+d+e+f+g)

The goal is to figure out what a+b+c+d+e+f+g is equal to. This is equal to the length of segment PQ since the 7 letters are pieces of segment PQ (i.e., I'm using the segment addition postulate).

In other words,

a+b+c+d+e+f+g = 12

3(a+b+c+d+e+f+g) = 3*12

3(a+b+c+d+e+f+g) = 36

Total distance traveled = 36

Helps pls Three generous friends, each with some cash, redistribute their money as follows: Ami gives enough money to Jan and To

Dominik [7]

Answer:

The total amount that all three friends have = $258

Step-by-step explanation:

Three friends: let their initial money be Ami's money =A, Jan = B, Toy = C

Toy started with $36 and ended with same amount

C = $36

After Ami gives, She is left with= A-x

Jan becomes= 2B

Toy becomes= 2C = 2×36 = 72

After Jan gives, Jan is left with = 2B-y

Ami now has = 2(A-x)

Toy now has = 2(72) = 144

After Toy gives, Toy is left with= 144-z

Ami now has = 2(2)(A-x) = 4(A-x)

Jan now has = 2(2B-y)

Since Toy is left with $36 at the end:

36 = 144-z

z = 144-36 = 108

So Toy spent $108 to double his two other friend's money

Both Amy and Jan had $108 in total when Toy had $144

Difference between the deductions across = $108

The total amount that all three friends have = 144+108

The total amount that all three friends have= $258

Which box-and-whisker plot is the correct drawing for the following data? 38, 29, 23, 23, 34, 25, 36, 35, 20, 17, 24, 25, 27, 20

Darina [25.2K]

Answer:

Step-by-step explanation:

38, 29, 23, 23, 34, 25, 36, 35, 20, 17, 24, 25, 27, 20, 30

17 20 20 23 23 24 25 25 27 29 30 34 35 36 38

Number of values = 15

Median = 8th value = 25

First quartile

First quartile would be the half of the median i.e., the 4th value

First quartile = 23

Third quartile

Third quartile would be the half of the median. Start counting from the 9th value.

Third quartile = 34

One whisker would start at 17 and the other would be at 38.

During a school race, Sonic ran around the entire track 5 times in 10 seconds. Everyone was shocked by his speed, which was equa

Aleonysh [2.5K]

Step-by-step explanation:

there is no diagram here.

I assume that the race track is a rectangle in the middle and two half-circles at the left and right ends, and that the length of the rectangle is D = 2R. which makes the rectangle actually a square, as the width is the diameter of the (half-)circles, which is also 2R.

Sonic ran the track 5 times in 10 seconds with a speed of 321 m/s.

that means he ran 10×321 m in 10 seconds = 3210 m.

so, 5 times the track is 3210 m, which means that the track itself is 3210/5 = 642 m long.

and based on the assumptions above the track consists of 2 times the length of the rectangle (or square), and the full circumference of a circle with radius R (2 half-circles make one full circle).

we know the formula for the circumference of a circle :

2×pi×radius

so, we have then

642 = 2×2R + 2×pi×R = R×(4 + 2×pi)

R = 642 / (4 + 2×pi) = 62.43201701...

and when using the requested "cut-off" pi = 3.14, we get

R = 642 / (4 + 2×3.14) = 62.45136187...

and that is rounded 62.5

so, the second answer option is correct.
