Answer:

5-3í

Step-by-step explanation:

Because the root of nine is three, equaling 5-3í

===========================================

Work Shown:

[tex]5 - \sqrt{-9}\\\\5 - \sqrt{-1*9}\\\\5 - \sqrt{-1}*\sqrt{9}\\\\5 - i*3\\\\5 - 3i\\\\[/tex]

In step 3, I used the rule [tex]\sqrt{x*y} = \sqrt{x}*\sqrt{y}[/tex]

Afterward, we use the definition that [tex]i = \sqrt{-1}[/tex]

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

6x - 5 = 67

6x = 72

x = 12

Step-by-step explanation:

setting the equation and variable x to the number

6 times the number and its difference to five is 67

plus five on both sides

divide both sides by 6

answer is 12

Answer:

6x-5=67

move all terms that don't contain x to the right side and solve

x=12

6(12)-5=67

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.

Answer:

x = 4.5 m ⇒ A

Step-by-step explanation:

The sides of similar triangles are proportion, that means the ratio between the corresponding sides are equal

In the given figure

∵ The two triangles are similar

∵ 2 m and x are corresponding sides

∵ 4 m and 9 m are corresponding sides

∴ [tex]\frac{2}{x}[/tex] = [tex]\frac{4}{9}[/tex]

→ By using cross multiplication

∴ x × 4 = 2 × 9

∴ 4x = 18

→ Divide both sides by 4 to find x

∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{18}{4}[/tex]

∴ x = 4.5 m

4.5m they are correct
