Answer:

15)   C (3, -4)

16)   B (-1, 1)

Step-by-step explanation:

8x + 6y = 0

8x + 2y = 16

8x + 2y = 16

8x = 16 - 2y

x = 2 - 1/4y

8x + 6y = 0

8(2 - 1/4y) + 6y = 0

16 - 2y + 6y = 0

16 + 4y = 0

4y = -16

y = -4

8x + 2y = 16

8x + 2(-4) = 16

8x - 8 = 16

8x = 24

x = 3

________________

-20x - 3y = 17

10x - 4y = -14

-20x - 3y = 17

-20x = 17 + 3y

x = -17/20 - 3/20y

10x - 4y = -14

10(-17/20 - 3/20y) - 4y = -14

-8.5 - 1.5y - 4y = -14

-8.5 - 5.5y = -14

-5.5y = -5.5

y = 1

-20x - 3y = 17

-20x - 3(1) = 17

-20x - 3 = 17

-20x = 20

x = -1

Answer:

Nathaniel ran fastest

Step-by-step explanation:

For Joseph

Joseph ran 2 3/4 miles 2 /5 of an hour.

Speed = Distance/Time

Speed = 2 3/4 miles ÷ 2/5 hour

= 11/4 ÷ 2/5

= 11/4 × 5/2

= 55/8 miles/hour or 6.875 miles/hour

How fast did he run in 1 hour? (try to leave your answer in a fraction)

Hence, this is calculated as:

2/5 hour = 55/8 miles per hour

1 hour = x

Cross Multiply

x = 55/8 ÷ 2/5

x = 55/8 × 5/2

x = 275/16 miles per hour

x = 17 3/16 miles per hour

Nathaniel ran LaTeX: 8 2/3 miles in 4 /3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction)

Speed = Distance/Time

Speed = 8 2/3 miles ÷ 4/3hour

= 26/3 ÷ 4/3

= 26/3 × 3/4

= 26/4 miles/hour

How fast did he run in 1 hour? (try to leave your answer in a fraction)

Hence, this is calculated as:

4/3 hour = 26/4miles per hour

1 hour = x

Cross Multiply

x = 26/4 ÷ 4/3

x = 26/4 × 3/4

x = 78/16 miles per hour

x = 4 14/16 miles per hour

= 4 7/8 miles per hour

Who ran the fastest, Nathaniel or Joseph?

Hence, from the calculation above, Nathaniel ran fastest

Step-by-step explanation:

Answer:

The correct answer is 8.

Step-by-step explanation:

There are 2 ways that you can win first prize and your mom can win the second prize.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

There are 10 people who entered the drawing.

Since the prizes are awarded at random, the probability of you winning the first prize is 1/3, and the probability of your mom winning the second prize is 1/2.

We can use the multiplication principle of counting to find the number of ways that you can win first prize and your mom can win the second prize.

The number of ways that you can win first prize is 1 since there is only one first prize and you are one of the 10 people who entered.

Once the first prize winner is chosen, there are 9 people left, and the number of ways that your mom can win the second prize is 1 out of 9.

The total number of ways that you can win first prize and your mom can win the second prize is:

1 × 1/3 × 1/2 × 9 = 3/2

However, the answer cannot be a fraction or decimal, since we are counting the number of ways in which events can occur.

Therefore, we round up to the nearest integer and get:

3/2 ≈ 2

Therefore,

There are 2 ways that you can win first prize and your mom can win the second prize.

Step-by-step explanation:

Answer:

its 1/3 of the volume of a cyinder with the same base

Step-by-step explanation:

a pyramid has the same policy with prisms of the same base

Volume is a three-dimensional scalar quantity. If the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Assume a cone and a cylinder such that the radius of the base of both the figures is r units, while the height of the cone and cylinder both is h units.

The volume of the cone with radius r units and height h units now can be written as,

Volume of the cone = (1/3) × π × r² × h units³

The volume of the cylinder with a radius of r units and the height of h units now can be written as,

Volume of the Cylinder = π × r² × h units³

Taking the ratio of the volume of the cone and the volume of the cylinder,

Volume of the cone/Volume of the cylinder = (1/3)πr²h units³ / πr²h units³

Volume of the cone/Volume of the cylinder = 1/3

Volume of the cylinder = 3 × Volume of the cone

Hence, if the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.
