A pilot flew a 400-mile flight in 2.5 hours flying into the wind . Flying the same rate and with the same wind speed, the return trip took only 2hours with a tailwind

Answers

Answer:

20

Step-by-step explanation:

pilot flew a 400-mile flight in 2.5 hours flying into the wind . Flying the same rate and with the same wind speed, the return trip took only 2hours with a tailwind

The speed can be defined as the ratio distance over time, but in this case the pilot is flying at the speed of the plane as well of speed of the wind. We can denote speed of plane as "s" and speed of the wind as "k"

Then the speed of the plane=(s-k) this is because it is moving in the opposite direction of the wind.

But From the question, the plane distance=400mile and the corresponding time =2.5 h

Then the speed of the plane=(s-k) =400mile/2.5

=160mph

By the time it return from trip, the speed the plane flew with is (s+k) because the wind is at the rear.

From the question, the plane distance=400mile and the corresponding time =2 h

Then (s+k)= (400/2)

(s+k)=200mph

The total number of equally-sized tiles on a circular floor is Area.

Given that, the total number of equally-sized tiles on a circular floor.

What is area of a circle?

The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.

The area of a circle is the amount of space enclosed within the boundary of a circle. The region within the boundary of the circle is the area occupied by the circle. It may also be referred to as the total number of square units inside that circle.

Hence, the total number of equally-sized tiles on a circular floor is Area.

A= 3(2)-2 which is A= 6-2 = 4

If we do the same for all of them then they would look like:

B= 3(4)-2

12-2= 10

The ratio of children to adults at the football game was 23. If there were 140 children at the football game,
how many adults were there?

Answers

Answer:

Therefore, the number of adults at the football game was 6.

Step-by-step explanation:

Let A represents the number of adults and C represents the number of children.

Therefore, the ratio of children to adults is given as follows:

23:1 = C:A ....................... (1)

Since C = 140, this is substituted into equation (1) as follows:

23:1 = = 140:A ....................... (2)

Transforming equation (2) and solve for A, we have:

23 / (23 + 1) = 140 / (140 + A)

23 / 24 = 140 / (140 + A)

0.958333333333333 = 140 / (140 + A)

0.958333333333333 (140 + A) = 140

(0.958333333333333 * 140) + 0.958333333333333A = 140

134.166666666667 + 0.958333333333333A = 140

0.958333333333333A = 140 -134.166666666667

0.958333333333333A = 5.833333333333

A = 5.833333333333 / 0.958333333333333

A = 6.08695652173878

Rounding to a whole number, we have:

A = 6

Therefore, the number of adults at the football game was 6.

solve the system equation
x-2y=27
y=5x

A (-4,-20)
B (3,25)
C (-3,-16)
D (-3,-15)​

Answers

Answer:

We will use substitution to solve this system for x.

[tex]x - 2y = 27\\y = 5x\\\\x - 2(5x) = 27\\\\x - 10x = 27\\\\-9x = 27\\\\x = -3[/tex]

Now that we know what x is, we can determine y by pluging in -3 for x in one of the original equations. I will use the first one.

[tex]-3 - 2y = 27\\\\-2y = 30\\\\y = -15\\[/tex]

We now have our solution.

D. [tex](-3, -15)[/tex]

We can check our answer by pluging the solution into one of the original equations to see if both sides equal each other. I will use the first equation.

[tex]-3 - 2(-15) = 27\\\\-3 + 30 = 27\\\\27 = 27[/tex]

Since the equation checks out, our solution is correct.

Oliver shot 8 free throws at practice, making 6 free throws and missing 2 free throws. If Oliver equally likely to make a free throw as he is to miss a free throw, find the probability of this outcome by expanding (m + n)8. Round to the nearest percent if necessary.

Answers

Answer: m

8 + 8 m 7 n + 28 m 6 n 2 + 56 m 5 n 3 + 70 m 4 n 4 + 56 m 3 n 5 + 28 m 2 n 6 + 8 m n 7 + n 8

Step-by-step explanation: Just use binomial theorem

The probability of this outcome by expanding (m + n)8 is 4.

What is Probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Given:

Total free shots = 8

Oliver make free shots =6

Oliver missed free shots = 2

As, Oliver wanted the free throw and the free throw he missed turn both equal.

So,

=8 / 2

= 4.

Hence,  probability of this outcome by expanding (m + n)8 is 4.

A company has 40 executives and 120 customer service representatives. If these are the only

employees, what percentage of the employees are executives? Explain how you determined the

percentage of employees are executives.

Answers

Answer:

25%.

Step-by-step explanation:

From the question given above, the following data were obtained:

Number of Executives = 40

Number of customer service representatives = 120

Percentage of the employees that are executives =?

Next, we shall determine the total number of employees in the company. This can be obtained as follow:

Number of Executives = 40

Number of customer service representatives = 120

Total number of employees =?

Total number of employees = (Number of Executives) + (Number of customer service representatives)

Total number of employees = 40 + 120

Total number of employees = 160

Finally, we shall determine the percentage of the employees that are executives as follow:

Number of Executives = 40

Total number of employees = 160

Percentage of the employees that are executives =?

Percentage = Number of Executives/ total employees × 100

Percentage = 40/160 × 100

Percentage = 0.25 × 100

Percentage = 25%

Therefore, the percentage of the employees that are executives is 25%
