Answer:
(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.
Step-by-step explanation:
The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Answer:
Airplane A has a lesser Interquartile range.
Step-by-step explanation:
To find the interquartile range, subtract the lower quartile from the upper quartile.
Airplane A = Upper quartile - lower quartile
Airplane A = 225 - 209 = 16
Airplane B = Upper quartile - lower quartile
Airplane B = 230 - 205 = 25
Therefore airplane a has a lesser interquartile range.

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.
what is the radius of a button if the circumference is 3 1/2 in
Answer: 0.557 in
Step-by-step explanation:
We will use the formula for the circumference of a circle, substitute known values, and solve for r (radius). 3 1/2 = 3.5.
Given:
C = 2πr
Substitute known values:
(3.5) = 2πr
Divide both sides of the equation by 2π:
(3.5) = 2πr
r = 0.557 in
Polygon ABCD with vertices at A(1, 1), B(3, 1), C(3, 2), and D(1, 2) is dilated to create polygon A′B′C′D′ with vertices at A′(3, 3), B′(9, 3), C′(9, 6), and D′(3, 6). Determine the scale factor used to create the image.
3
2
one half
one third
To determine the scale factor used to dilate polygon ABCD to A′B′C′D′, we can compare the corresponding side lengths.
The distance between A(1, 1) and B(3, 1) is 2 units, and the distance between A′(3, 3) and B′(9, 3) is 6 units, so the horizontal side has been scaled by a factor of 6/2 = 3.
Similarly, the distance between A(1, 1) and D(1, 2) is 1 unit, and the distance between A′(3, 3) and D′(3, 6) is 3 units, so the vertical side has been scaled by a factor of 3/1 = 3.
Since both scaling factors are equal to 3, the overall scale factor used to dilate the polygon is 3. Answer: 3.

ChoiceD: a circle graph titled social media usage, with four sections labeled picturegram 17 percent, tweeter 48 percent, vidtok 25 percent, and headbook 10 percent
Answer:
The answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Step-by-step explanation:
By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.
85 ÷ 5 = 172
40 ÷ 5 = 48
125 ÷ 5 = 25
50 ÷ 5 = 10
Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
What mixed number represents 30/8
Answer:
3 6/8
Step-by-step explanation:
30÷8=3 6/8
8×3=24
30-24=6
Answer:
The mixed that represents 30/8 is --> 3 3/4
Step-by-step explanation:
Step 1: Find the whole number
We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.
30/8= 3.75 = 3
Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.
Step 2: Get the new numerator
To work this out we'll use the whole number we calculated in step one (3) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:
30 - (8 x 3) = 6
Step 3: Our mixed fraction
We've now simplified 30/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:
3 6/8
Step 4: Simplifying our fraction
In this case, our fraction (6/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 6 and 8 is 2.
We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.
6/2 = 3
8/2 = 4
When we put that together, we can see that our complete answer is:
3 3/4

what is the perimeter of a stained glass semi-circle if the diameter is 3 feet?
Answer:
The perimeter of the stained glass semi-circle is 3π feet.
Step-by-step explanation:
The perimeter of a semi-circle is half of the circumference of the full circle with the same diameter.
The circumference of a circle with diameter 3 feet is:
C = πd = π(3) = 3π feet
Therefore, the circumference of the full circle is 3π feet, and the circumference of the semi-circle is half of that:
C(semi-circle) = 1/2(3π) = 3/2π feet
However, the stained glass semi-circle has a curved edge, so we need to add the length of that edge to the perimeter. The curved edge of a semi-circle is half of the circumference of the full circle, or:
C(curved edge) = 1/2(2πr) = πr, where r is the radius of the circle
Since the diameter of the circle is 3 feet, the radius is half of that:
r = d/2 = 3/2 feet
So the curved edge of the stained glass semi-circle is:
C(curved edge) = π(3/2) = 3/2π feet
Adding this to the straight edge perimeter, we get:
Perimeter = C(semi-circle) + C(curved edge)
= (3/2π) + (3/2π)
= 3π feet
Therefore, the perimeter of the stained glass semi-circle is 3π feet.

Triangle XYZ is similar to triangle JKL.
triangle XYZ with side XY labeled 8.7, side YZ labeled 7.8, and side ZX labeled 8.2 and triangle JKL with side JK labeled 10.44
Determine the length of side LJ.
8.79
9.36
9.84
10.13
Answer:
C) 9.84
Step-by-step explanation:
JK ~ XY
XY = 8.7
JK = 10.44
10.44/8.7 = 1.2
That’s the scale or dilation
LJ ~ ZX
ZX = 8.2
8.2 X 1.2 = 9.84
LJ = 9.84
The length of side LJ in the triangle JKL is 9.36.
We are given that triangle XYZ is similar to triangle JKL, which means that the corresponding sides are proportional.
We are also given the lengths of the sides of triangle XYZ, so we can use these lengths to find the corresponding sides of triangle JKL.
The ratio of the corresponding sides of triangle XYZ to triangle JKL is:
XY : JK = 8.7 : 10.44
YZ : KL = 7.8 : 9.36
ZX : LJ = 8.2 : x
Since the two triangles are similar, we know that the ratios of the corresponding sides are equal.
Therefore, we can set the two ratios equal to each other and solve for x, the length of side LJ:
8.7 / 10.44 = 7.8 / 9.36 = 8.2 / x
Cross-multiplying, we get:
8.7 * x = 10.44 * 7.8
x = (10.44 * 7.8) / 8.7
x = 9.36
Therefore, the length of side LJ is 9.36.

Do not play soccer:___ 45% / 55% / 100%
Total : _____________112% / 88% / 200%
Step-by-step explanation:
play soccer: total is 90, to find percentage :
60/90 = 0.6666666667 estimated = 0.67
0.67 x 100 = 67%
30/90 = 0.3333333333 estimated = 0.33
0.33 x 100= 33%
33% + 67% = 100%
don’t play soccer : total is 60, to find percentage:
27/60 = 0.45
0.45 x 100 = 45%
33/60= 0.55
0.55 x 100 = 55%
45% + 55% = 100%
Total for first column going down
67% + 45% = 112%
Second column going down

Step-by-step explanation:
To find the interquartile range, we first need to find the values of the first and third quartiles.
The median of the data set is 4. To find the first quartile, we take the median of the lower half of the data set:
1 1 3 3 | 4 4 5 7 7
^
First quartile = 3
To find the third quartile, we take the median of the upper half of the data set:
1 1 3 3 | 4 4 5 7 7
^
Third quartile = 7
The interquartile range is the difference between the third quartile and the first quartile:
7 - 3 = 4
Therefore, the interquartile range of the data set is 4.
