The aspect ratio of a television or movie

screen is the ratio of the width of the screen

to its height. A high-definition television

has an aspect ratio of 16:9. The movie

Star Wars was filmed in cinemascope,

which has an aspect ratio of 2.35:1. Are

these aspect ratios equivalent? Explain.

Step-by-step explanation:

The probability of rolling any number on a 6-sided die is 1/6.

The probability of rolling a 4 = 1/6

The probability of rolling a 6 = 1/6

The probability of rolling 4 and then 6 = (1/6) * 1/6) = 1/36

Answer:

g = 128 deg

k = 97 deg

h = 52 deg

m = 83 deg

By using vertical angles and by knowing how to solve for adjacent supplementary angles, you can find the answer.

g: 128 deg (vertical angles; opposite side is congruent)

k: 97 deg (vertical angles; opposite side is congruent)

h: 52 deg (supplementary angles = 180 deg; 180 - 128 = 52)

m: 83 deg (supplementary angles = 180 deg; 180 - 97 = 83)

Answer: 17500

Step-by-step explanation: 7000 + 15000 + 22000 + 23000 +38000/ 6

The difference between a collection of numbers' highest and lowest values is known as the range.

The mean(average) salary exists 17500.

The range salary exists 35000.

Range, which shows statistical dispersion, is the size of the smallest interval in descriptive statistics that encompasses all the data. It is best suited to capturing the dispersion of tiny data sets because it only depends on two observations.

The difference between the highest and lowest values for a given data collection is the 35000in statistics. For instance, the range will be 10 - 2 = 8 if the given data set is 2, 5, 8, 10, and 3. As a result, the range may alternatively be thought of as the distance between the highest and lowest observation.

The salaries of six employees are $3000, $7000, $15,000, $22,000, $ 23,000, and $38,000.

a) Mean = Sum of terms / Number if terms

substitute the values in the above equation, we get

= 7000 + 15000 + 22000 + 23000 + 38000/ 6

= 17500

Therefore, the mean(average) salary exists 17500.

b) The maximum is $38,000 and the minimum is $3000 then the range exists

Range = maximum - minimum

substitute the values in the above equation, we get

Range = $ 38,000 - $ 3000

= $ 38,000 - $ 3000

= $ 35000

Therefore, the range salary exists 35000.

Moving downstream (with the current), the boat moves at a rate of (252 mi)/(12 h) = 21 mph. Upstream (against the current), it moves at a rate of (252 mi)/(84 h) = 3 mph.

When traveling downstream, the boat's speed is the sum of its own speed in still water and the speed of the current. It's the same going upstream, but the boat and current move in opposite directions. Let b and c denote these speeds, respectively. Then

downstream: b + c = 21 mph

upstream:      b - c = 3 mph

Adding these equations eliminates c and lets us solve for b :

(b + c) + (b - c) = 21 mph + 3 mph

2b = 24 mph

b = 12 mph

Now solve for c :

12 mph + c = 21 mph

c = 9 mph

Answer:

6/142 > 4/136

Step-by-step explanation:

6/142 = 0.04225352113

4/136 = 0.02941176471

Answer:

6/142

Step-by-step explanation:

because 6/142 in percentage form is .04225 and 4/136 in its' percentage form is .0294. Basically if you don't know the answer then just change it from a fraction to a percent to see it better.

Answer:

A(x) = x(200-x)

Step-by-step explanation:

400 feet of fencing to enclose a rectangular dog exercise pen means the perimeter of rectangle is 400 feet

If x is length and y is breadth. Perimeter is given by :

P = 2(x+y)

400 = 2(x+y)

⇒ (x+y) = 200 .....(1)

y = 200-x

Area of a rectangle is given by :

A = xy

A(x) = x(200-x)

Hence, the area as a function of length of rectangle is x(200-x).

Answer:

[tex]10^{4}[/tex]

Step-by-step explanation:

square has 4 sides each side is 10cm

The area of a square with a side length of 10 cm written in exponent form is  10² cm².

The perimeter of any given 2D figure is the sum of the lengths of all the sides.

We know the area of a square is a product of its two sides.

Assuming the length of a side of a square is a unit.

∴ The area of the square is (a×a) sq units,

and we know that a×a = a¹×a¹ = a¹⁺¹ = a².

So, given a square has a side length of 10cm.

∴ The area of the square will be (10×10) sq cm.

= 10² cm².

Answer:

x < -8, third from top option in the picture.

Step-by-step explanation:

5(2x - 4) < -100

10x - 20 < -100

10x < -80

x < -8

Answer:

3rd option from the top (open circle arrow going left)

Step-by-step explanation:

5(2x-4) is less than - 100

5 times 2x is 10x and 5 times - 4 is - 20 so,

10x - 20 is less than - 100

now do inverse operations to isolate x, add 20

- 20 plus 20 is 0 and -100 plus 20 is - 80

10x is less than -80

divide both sides by 10 and you get,

x is less than - 8

What if there were two more apples? Now you have 2 apples next to another pair of apples. Now let's count all the apples.

One apple,

Two apples,

Three apples,

Four apples.

There are 4 apples all together.

So, 2 + 2 has a sum of 4.

Answer: 3x-4

Step-by-step explanation:

If jennifer is x, and Chelsea bought 3 times more than her

then she bought 3x

but since shes giving 4 away to her teacher you subtract 4 from 3x

so the answer is 3x-4

Jennifer bought x books, so let b represent books.

Chelsea bought 3 times more books than Jennifer, so we write b x 3.

She gave 4 books to her teacher, so we write - 4.

The final answer is b x 3 - 4. Hope this helps!
