what is the radius of a button if the circumference is 3 1/2 in

Answers

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.

one third

Answers

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.

Answers

Answer:

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.

Divide negative 6 and 2 over 5 ÷ negative 4 and 3 over 7.

negative 224 over 155

What mixed number represents 30/8

Answers

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

Triangle XYZ is similar to triangle JKL.

Determine the length of side LJ.

8.79
9.36
9.84
10.13

Answers

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.

what is the perimeter of a stained glass semi-circle if the diameter is 3 feet?

Answers

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.

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%

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

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?

Answers

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.

The ratio of Liz’s age to Freya’s is 1:3
