On a DVD, information is stored on bumps that spiral around the disk. There are 73,000 ridges (with bumps) and 73,000 valleys (without bumps) across the diameter of the DVD. What is the diameter of the DVD in centimeters? Round your answer to the nearest whole number.

On A DVD, Information Is Stored On Bumps That Spiral Around The Disk. There Are 73,000 Ridges (with Bumps)

Answers

Answer 1

Answer:

I pretty sure it's 8cm.

Step-by-step explanation:

I multiplied 73,000 by 0.000074, which resulted in 5.402.
Then, I multiplied 73,000 by 0.000032, which resulted in 2.336.
I added the products together, which gave a sum of 7.738.
Then I rounded to the nearest whole number, which is 8, because the tenth in the decimal (.7) rounds up because it is >4.

question 1. A card is pulled from a standard deck of cards. Find the probability of getting a 2 or King.

question 2. A 6-sided number cube is rolled. Find the Probability of NOT getting a 2 or 5.

Answers

Answer:

question 1) 8/52

question 2) 2/3

Step-by-step explanation:

question 1) there are 52 cards in a standard deck. Of those 52 cards there are 4 of each card (e.i 4 aces, 4 kings, 4 tens, etc.). So, 4 of 52 cards are 2s and 4 of 52 cards are Kings. 4 + 4 is 8, so the probability of getting a 2 or a King is 8/52.

question 2) There are 6 numbers on a 6-sided number cube-- 1, 2, 3, 4, 5, 6. The numbers 2 and 5 can be crossed out because we want to find the probability of NOT getting a 2 or 5. This leaves you with the numbers 1, 3, 4, and 6. That is 4 of 6 numbers. Therefore the probability of NOT getting a 2 or 5 is 4/6. We can simplify 4/6 to 2/3.

Answer:

68 in³

Step-by-step explanation:

To find the volume of the figure, we first need to find the volumes of the 2 triangular prisms and 1 rectangular prism.

Triangular prism

[tex]{\boxed{\text{Volume}= \text{base area ×height}}}[/tex]

The base area here is the area of the triangular face, since it is the face that repeats itself throughout the entire length/height to form the volume of prism.

Base area

= area of triangle

= ½(base)(height)

= ½(2)(3)

= 3 in.

Height= 2 in.

Volume

= 3(2)

= 6 in³

Volume of rectangular prism

Volume

= base area ×height

= length ×breadth ×width

= 14(2)(2)

= 56 in³

Total volume

Volume of figure

= 2(6) +56

= 12 +56

= 68 in³

A box has the shape of a rectangular prism with height 31 cm. If the height is increased by 0.9 cm, by how much does the surface area of the box increase? 31 cm 12 cm 7.2 cm Use pencil and paper. Show your work. Then show a second way to solve the problem. Explain which way you like better and why. The surface area increases by cm2​

Answers

First size: SA1 = 2B + Ph, where B = area of the base of the figure, P = perimeter of the base and h = height

SA1 = 2(12*7,2) + (12+7,2)*31 = 172.8 + 595.2 = 768 cm^2

Second size: SA2 = 2B + ph2 (where h2 is the new height, 31.9 cm)
SA2 = 2(12*7,2) + (12+7,2)*31.9 = 785.28 cm^2

It increases (by rounding it down) by 17 cm^2.

What is the distance around the circle?
314 feet

20 feet

31.4 feet

62.8 feet

Answers

Answer:

62.8 feet

Step-by-step explanation:

The distance around the circle is known as the circumference

We can find the circumference using the formula C = 2πr

Where r = radius

The radius is a line that goes from the center of the circle to any point on the circle.

Here, we are given that the radius is 10 feet

Plugging in the value of the radius into the circumference formula

Again we have C = 2πr

==> plug in r = 10

C = 2π(10)

==> multiply 10 and 2

C = 20π

==> multiply 20 and π (which has a value of about 3.14)

C = 62.8 ( rounded )

So the distance around the circle is about 62.8 feet.

Answer:

62.8 feet

Step-by-step explanation:

We are given:

[tex]\text{Radius of circle} = \bold{10} \ \bold{feet}[/tex]

Definition of radius: The radius of the circle is the line that starts from the center point and ends at any point of the circle.

The formula that expresses the circumference of a circle is 2πr.               [Where "r" represents the radius of the circle]

Let's substitute the radius in the circumference formula and simplify it to determine the distance around the circle (circumference).

[tex]\implies \text{Circumference of circle} = 2\pi r[/tex]

[tex]\implies \text{Circumference of circle}= 2\pi (10)[/tex]                    [tex]\implies \text{Circumference of circle} = 20\pi[/tex]

Let us take π as 3.14. Then, we get:

[tex]\implies \text{Circumference of circle} = 20(3.14) = 2(31.4) = \boxed{62.8 \ \text{feet}}[/tex]

Therefore, the distance around the circle (circumference) is 62.8 feet.

a) list the first five terms of each pattern

b) graph ordered pairs from each pattern using blue for pattern A and orange for Pattern B

c) describe the relationship between corresponding terms of each pattern

d) explain why this relationship exists between the corresponding terms.

Answers

Answer:

a) pattern a: 4,8,12,16,20

   pattern b: -8,-16,-24,-32,-40

0,4, 8, 12, 16 are the five terms of pattern A and 0,-8, -16, -24, -32 are the five terms of pattern B and the relationship between both the patterns is linear.

What is Sequence?

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

For pattern A:

0, 0+4, 4+4=8, 8+4=12, and 12+4=16

I.e 0,4, 8, 12, 16 are the five terms of pattern A

For pattern B:

0, 0-8=-8, -8-8=-16, -16-8=-24, -24-8=-32

I.e 0,-8, -16, -24, -32 are the five terms of pattern B

The relationship between two patterns is linear

The relationship exist between two patterns because both sequences are arithmetic sequences

Hence, 0,4, 8, 12, 16 are the five terms of pattern A and 0,-8, -16, -24, -32 are the five terms of pattern B and the relationship between both the patterns is linear.

From a y axis point is -5

Thus coordinates are (7,-5) because in any point coordinates are always in the form (x,y).

Hope this Helps! :)

Answer:

D. (7, -5)

Step-by-step explanation:

A coordinate is a point on a graph. A coordinate is written as (x, y), where x represents the x-value and y represents the y-value.The x-value represents the number of units left or right from the origin (0, 0), and it becomes negative as it moves left and positive as it moves right.The y-value represents the number of units up or down from the origin (0, 0), and it becomes negative as it goes down and positive as it goes up.For example, the coordinates (-4,8) indicate that the x-value moves four units to the left and the y-value moves eight units up.

We are asked to find the coordinates of point A:

The x-value is positive 7, indicating that the point moved seven units to the right of the origin.The y-value is negative 5, indicating that the point dropped five units from the origin.Our coordinates would be: (7, -5)

it would probably be answer 1, the one at the top.

Step-by-step explanation:

So, if you gather -1/2 and then flip which makes -2/1 to cancel it out, then you do the same with -16, and then put -16/1(-2/1) then multiply -16 and -2, which will give you 32.

Answers

Answer:

x = 10

Step-by-step explanation:

Both obects are similar right. That means that they must have similar angles, similar sizes and similar scale factors.

For me by just looking at the figires I can conclude a similar scale factor which is 1.7. However we are going to calculate the scale factor.

First we must take notice that the triangle D'E'F' is an enlargement. So to find the scale factor we must the same sides of both triangle and divide the larger sid by the smaller side.

68 ÷ 40 = 1.7

Now that we have the scale factor (1.7) we can now find x.

The similer side D'F' = 17 and DF = x.

We are gonna use the scale factor to divide D'F' to find DF.

17 ÷ 1.7 = 10

Therefore x is 10

Answer:

The Stores profit is 70% or $59.5

How?

The reason is because if it's selling it for 100% of the price, then that means that the store bought it for 85 dollars, and it's selling it for 85 dollars, and that's 0% profit. But because the store has bought it for 100%, and then it's charging another 70% of the price, so the store's profit is 70%.

Now, we find 70% of 85 dollars, which will be the STORE'S PROFIT AMOUNT!

1. Convert percentages into fractions or decimals

For fraction: divide 70 by 100 and remove the % sign.

[tex]{70}\%=\frac{70}{100}[/tex]

For decimal: move the decimal point 2 places to the left and remove the % sign.

[tex]{70}\%=0.7[/tex]

2. Multiply the decimal or fraction by the quantity that equals 100%

[tex]100[/tex]%[tex]=85[/tex]

[tex]\frac{70}{100} *85=0.7*85=59.5[/tex]

70% of 85 is 59.5Store's profit is $59.5

Extra info:

170% of 85 = 144.5

70% of 85 = 59.5
