A man flies a small airplane from Fargo to Bismarck, North Dakota- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1.2 hours. What is the planes speed in still air, and how fast is the wind blowing?
1) His plane speed equals ______ mph
2) The wind speed equals ______ mph
Answer:
1.) 120 mph
2.) 30 mph
Step-by-step explanation:
Given that a man flies a small airplane from Fargo to Bismarck, North Dakota- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1.2 hours. What is the planes speed in still air, and how fast is the wind blowing?
Let the wind speed = w
and the plane speed = p
From the first sentence,
P - w = 180/ 2
P - w = 90 ....... ( 1 )
From the second statement,
P + w = 180/1.2
P+ w = 150 ...... ( 2 )
Solve equation 1 and 2 simultaneously
P + w = 150
P - w = 90
Add the two equations
2P = 240
P = 120 mph
Substitute p in equation 1
W = 150 - 120
W = 30
Therefore, the wind speed is 30 mph and the plane speed is 120 mph

Find the angle PQR [Geometry]
Answer:
5⁰
Step-by-step explanation:
Angle on A STRAIGHT line sums up to 180⁰
angle PQR and angle RQS are both on a straight line therefore they sum up to 180⁰
4x+129+5x+6=180
then here you group like terms
4x+5x=150-129-6
9x=45
divide both sides by 9
9 dividing 45 is 5

Tropical Storm Zeta will bring 0.36 in. of rain to New Orleans. Which fraction is equivalent to this amount of rain in inches?
Answer: 9/25 inches of rain
Step-by-step explanation: Put the decimal (0.36) over its place value (100), which turns it into 36/100. Now, simplify by dividing the numerator (36) and the denominator (100) by the greatest common factor (4), to get the answer 9/25.

Month June July Aug Sept Oct
Rainfall (in.) 6.14 7.19

2.43
2. The table shows monthly rainfall in inches for
five months. Identify the outlier in the data set.
Determine how the outlier affects the mean,
median, and mode of the data. Then tell which
measure of center best describes the data with
and without the outlier. Round to the nearest
hundredth. Justify your selection.
okay, first to figure out the IQR of the table you need to organize them from least to greatest.
2.43, 6.14, 6.47, 7.19, 8.38, 8.63
to find the middle number of all of these you add them all together and divide by 6, which is the total amount of numbers there.
2.43 + 6.14 + 6.47 + 7.19 + 8.38 + 8.63 = 39.24
39.24 / 6 = 6.54
now that we have the IQR, next we find the outlier. to find the outlier you multiply the IQR by 1.5 which is 6.54 x 1.5 = 9.81 <- outlier
Outliers affect the mean value of the data but have little effect on the median or mode of a given set of data.
2.43 + 6.14 + 6.47 + 7.19 + 8.38 + 8.63 + 9.81 = 49.05
49.05 / 7 = 7.00 (Rounded)

10 units is the distance between point A and point C on the number line.
What is Number system?A number system is defined as a system of writing to express numbers.
We need to find the distance between point A and point C on the number line.
A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.
The length along a line or line segment between two points on the line or line segment is known as distance.
The point A is at -3.
The point C is at 7
Now the distance between A and C is AC.
AC=OC-OA
=7-(-3)
=7+3
=10
Hence, 10 units is the distance between point A and point C on the number line.

Player 1 and player 2 are running laps around a field. Player 1 runs 1 lap every 4 minutes, while player 2 runs 1 lap every 15 minutes. If player 1 and player 2 begin their run at the same time and location on the field, in how many minutes will they meet to begin their next lap together?
Answer:
15 min
Step-by-step explanation:
if it takes Player 1 one min he will meet player two at there second lap after 15 min
If player 1 and player 2 begin their run at the same time and location on the field, In 60 minutes will they meet to begin their next lap together.
What is LCM?The LCM of any two is the value that is evenly divisible by the two given numbers.
Given,
Player 1 and player 2 are running laps around a field
Player 1 runs 1 lap every 4 minutes,
player 2 runs 1 lap every 15 minutes
We need to find in how many minutes will they meet to begin their next lap together
We need to find the LCM of 4 and 15 to find the answer
4: 4, 8,12,16, 20,24,28,32,36,40,44,48,52,56,60
15: 15,30,45,60
The least common multiple of 4 and 15 is 60.
The two players meet at the same point after 60 minutes.
Hence If player 1 and player 2 begin their run at the same time and location on the field, In 60 minutes will they meet to begin their next lap together.
