Here are the rules of a game.
Each person chooses heads or tails at random, then a coin is thrown.
People who choose the side shown by the coin are left in the game.
The rest are out of the game.
If a group of 1000 people are going to play this game, how many people might you
expect to be left in the game after 5 throws?

Answer:

1) 2² + 5² = ?²

2) 6² + ?² = 9²

3) 8² + 16² = ?²

4) 8² + ?² = 10²

Step-by-step explanation:

Because these are all right triangles, we can use the Pythagorean Theorem:

a² + b² = c²

Where c is the hypotenuse, the longest side of the triangle. It can be identified as being across from the right angle of the right triangle.

The legs are the two other sides of the triangle and they are interchangeable when placed in the Pythagorean Theorem.

Answer:

117

Step-by-step explanation:

Required number

[tex] = 65 \times \frac{9}{5} \\ \\ = 13 \times 9 \\ \\ = 117[/tex]

Answer:

27000in

Step-by-step explanation:

you have to multiply everything by 10 and then find the surface area again.

(length: 11in width: 5in height: 5in) * 10

(length: 110in

width: 50in

height: 50in

Finding the new surface area:

SA = 2(lw + lh + wh)

SA = 2((110)(50) + (110)(50) +(50)(50))

SA = 2(5500 + 5500 + 2500)

SA = 2(13500) = 27000

The can find this my matching each number of the chart with each diagram

It can't be the first one because the 17-19 isn't on 8, it is on 4

It can't be the second one because the 20-22 isn't on 7, it is on 9

It is the third one because all the number on the chart is matching with the numbers on the diagram

It can't be the fourth one because the 17-19 isn't on 8, it is on 4

1/6 of a bowl of batter

Step-by-step explanation:

Find out how much muffins is needed for 1 bowl.

2 bowls = 12 muffins

1 bowl = 12 ÷ 2 = 6 muffins

Since 1 bowl can fill 6 muffins, it's 1/6

Volume of a Cylinder: In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.

The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.Step-by-step explanation:

Answer:

read.

Step-by-step explanation:

The popularity of the Gutenberg press in Europe made books more accessible and motivated people want to learn how to READ.

This is evident in the fact that Johannes Gutenberg who was widely known as a printer was famous for inventing a means of producing books at a cheaper cost and portable size that is also durable and easy for distribution.

The result of this invention led to an increase in the availability of books and thereby enhance and motivate more people, not just the elites, to have access to books and READ them.

Answer:

Evergreen Eagle can will fly 1.56 km in 20 minutes.

Step-by-step explanation:

Speed of Evergreen Eagle = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

                                            = [tex]\frac{13}{1}[/tex]

                                            = 13 meters per second

With this speed Eagle can fly the distance in 20 minutes Or 120 seconds

= Speed × Time

= 13 × 120

= 1560 meters

Since, 1000 meters = 1 Km

1 meter = [tex]\frac{1}{1000}[/tex] km

Therefore, 1560 meters = [tex]\frac{1560}{1000}[/tex]

                                       = 1.56 km

Therefore, Evergreen Eagle can will fly 1.56 km in 20 minutes.

Answer:

10 is subtracted from a third of a number is greater than 22

Step-by-step explanation:

1/3n-10>22​

you subtract 10 from 1/3n

1/3 - 10 is greater than 22

so:

10 is subtracted from a third of a number is greater than 22

Answer:

The correct answer is:

Error made: The student multiplied only corresponding terms in each bracket with each other

Correction: Each term in one bracket is to be multiplied with every term in the next bracket

Step-by-step explanation:

The student paired the terms in the brackets into like terms and multiplied the like terms like this:

(2x + 2) × (4x - 1)  

collecting like terms: (2x, 4x) (2, -1)

(2x × 4x) (2 × (-1)) = 8x² - 2.

The above is the wrong way of expanding the bracket. The correct way of doing it is as follows:

(2x + 2) (4x - 1)

Each term in one bracket multiplies each term in the second bracket.

= 2x (4x - 1) + 2(4x -1)

= 8x² - 2x + 8x - 2

= 8x² + 6x - 2

Step-by-step explanation:

7.5 cups of raisins, 10 cups of peanuts and 5 cups of chocolate chips.

Step-by-step explanation:

We are given that,

The amount of ingredients needed for the trail mix are,

Raisins = \frac{3}{4}

4

3

cup

Peanuts = 1 cup

Chocolate chips = \frac{1}{2}

2

1

cup

Since, Kiran needs to make 10 cups of the trail mix.

The amount of ingredients needed will be,

Raisins = \frac{3}{4}\times 10

4

3

×10 = \frac{30}{4}

4

30

= 7.5 cups

Peanuts = 1 × 10 = 10 cups

Chocolate chips = \frac{1}{2}\times 10

2

1

×10 = 5 cups

Hence, the ingredients needed are 7.5 cups of raisins, 10 cups of peanuts and 5 cups of chocolate chips.

Answer:

$367.17

Step-by-step explanation:

we are find the cost of the car after 5 years

Using the compound interest formula;

A = P(1+r/n)^nt

Given

Principal P = $300

rate r = 5.2% = 0.052

Time t = 5years

Time of compounding n = 1/12 (monthly)

Substitute into the formula

A = 300(1+0.052(12))^5(1/12)

A = 300(1+0.624)^0.4167

A = 300(1.624)^0.4167

A = 300(1.2239)

A = 367.17

hence the amount of the car after 5years is $367.17

Answer:

$12

Step-by-step explanation:

$10 is   100% of the price

 The selling price is 120% of the price

x= selling price

10 -------------100%

x ----------------120 %

Cross multiplication

10x120 = 100x

1200 = 100x

Divide both sides by 100

12 = x

 Selling  price = $12
