The speed of plane in still air is 715 MPH and the speed of the wind is 65 MPH
Distance travelled by airplane = 3900 miles
Time taken by the plane to travel the distance with the wind = 5 hours
Time taken by the plane to travel the distance against the wind = 6 hours
Let the speed of the plane in still air be x
Let the speed of the wind be y
Finding the speed of the air and airplane when distance is covered with the wind using the formula:
Speed of airplane + Speed of wind = Distance/Time
x + y= 3900/5
x + y = 780------(1)
Finding the speed of the air and airplane when distance is covered against the wind using the formula:
Speed of airplane - Speed of wind = Distance/Time
x - y = 3900/6
x - y = 650------(2)
Equating (1) and (2) we get:
2x = 1430
x = 715
Putting x = 715 in (1) we get:
y = 65
So, Speed of airplane in still air is 715 MPH and Speed of wind is 65 MPH

For a school project, Samuel cuts 4/7-inch discs of metal. How many discs can he make from a metal post that mesures 1/3
foot in length?
If Samuel cuts [tex]\frac{4}{7}[/tex] inches discs of metal, then he can make 7 discs from a metal post that measures [tex]\frac{1}{3}[/tex] foot in length
Given,
The total length of metal post= [tex]\frac{1}{3}[/tex] foot
Convert foot to inches
1 foot = 12 inches
[tex]\frac{1}{3}[/tex] foot= 4 inches
The length of each disc of metal = [tex]\frac{4}{7}[/tex] inches
Number of metal post that he can cut = Total length of metal post / The length of each disc of metal
[tex]=\frac{4}{\frac{4}{7} } \\=4(\frac{7}{4})\\ =7[/tex]
Hence, if Samuel cuts [tex]\frac{4}{7}[/tex] inches discs of metal, then he can make 7 discs from a metal post that measures [tex]\frac{1}{3}[/tex] foot in length

Anna is analyzing her greeting card business's profits. She wants
more than 40% of the price pof her greeting cards to be profit.
If crepresents Anna's cost to make a greeting card, which inequality
represents the desired relationship between price and cost?
The relationship between the price and cost is p > c.
The cost of manufacturing a product has a direct bearing on its price and the revenue generated by each sale. The cost of a product or service is determined by the customer's willingness to pay. Profit is the sum of the price paid less the costs incurred.
The price of Anna's greeting cards is p.
The cost of making a single greeting card is c.
Anna wants the profit to be 40% of the price of her greeting cards.
Profit = 40% of p
Profit = 40% × p = 0.4p
Now, we know
Price = Profit + Cost
p = 0.4p + c
Therefore, the relationship between cost and price is given by inequality:
p > c

Answer:
y = 4x - 27
Step-by-step explanation:
The point (8,5) contains and x and y on the line. The x is 8 and the y is 5. Using this and the slope given we can write the equation. We need to solve for b.
y = mx + b
5 = 4(8) + b
5 = 32 + b Subtract 32 from both sides of the equation
-27 = b
y = mx + b

What is −10 + |−4| − |−12|?
Answer:
-18
Step-by-step explanation:
-10 + |-4| - |-12| Since there are the | |, then any negative number inside would become a positive as it will become its absolute value, which for -4, would be 4, because it is 4 spots away from the 0 on a number line and vice versa.
-10 + 4 - 12 Answering from left to right,
-10 + 4, if you would rather make it so they are both equal, you change the + to the opposite which would be - and change the 4 back to a negative because that is what it would be if you changed the equation to be subtraction instead to be easier as they would both be negatives now, so you would subtract -10 - -4 and get -6.
-6 - 12. Again, switch the - to the opposite, which is +, and then make 12 the opposite that it was before so they both share the same symbol, making it
-6 + -12, which would be -18.

One of the legs of a right triangle measures 2 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer: 3.5
Step-by-step explanation:
To find the length of the missing leg, we need to use the Pythagorean Theorem (a^2 + b^2 = c^2 where c is the hypotenuse)
1) Plug in numbers
2^2 + b^2 = 4^2
2) Square
4 + b^2 = 16
3) Flip Equation and Subtract
16 - 4 = b^2
16 - 4 = 12
4) Square Root of 12
The square root of 12 is ~3.46, so you need to round to the nearest tenth, which is 3.5
3(2x + 2) - (x − 4) < 18
To plot the graph of equation 3(2x + 2) - (x − 4) < 18, we need to simplify the equation of inequality first which can be simplified as
3(2x + 2) - (x − 4) < 18
6x + 6 -x+ 4 < 18
5x + 10 < 18
5x <18 - 10
5x < 8
x < 8/5
x < 1.6
So, we need to plot the line graph of the equation of inequality x < 1.6 which is attached to the solution where Blue is marked or plotted in the graph, and also note that at 1.6 there is a hollow circular mark which resents the inequality

Find the circumference and area of circle X if each unit on the graph measures 1 centimeter. Round answers to the
nearest tenth, if necessary.
The circumference and area of the circle are 13cm and 13cm^2 respectively
How to determine the valuesThe formula for circumference of a circle is expressed as:
Circumference = 2πr
From the graph shown, we have the radius of the circle as 2 cm
Substitute the value into the formula
Circumference = 2 × 3. 142 × 2
Multiply through
Circumference = 12. 568
Circumference = 13cm
The formula for area of a circle is expressed as:
Area = πr^2
Substitute the value into the formula
Area = 3. 142 × (2)^2
Area = 3. 142 × 4
Area = 12. 568
Area = 13cm^2
Thus, the circumference and area of the circle are 13cm and 13cm^2 respectively.

A car rental agency rent 190 cars per day at a rate of $40 per day for each one dollar increase in rate five fewer cars are rented at what rate should the cars be rented to produce the maximum income?
The rate that the cars should be rented to produce the maximum income is: 41 Dollars/Day, Maximum income 7615.
Rate and maximum incomeLet y represent the income
Let x represent the increase in rental price after increasing the rental price is 40+x.
Let 190-5x represent the number of cars rental after a rental price increase
Income expression
y=(190-5x) (40+x)
Let differentiate y with respect to x and set y' =0 to determine the maximum income
Hence,
y=(190-5x) (40+x)
=(190) (40) + 190 (x) -5x(40) -5x-(x)
=7600 +190x-200x-5x²
y= -5x² +10x+7600
Differentiate with respect to x
y'=d/dx ( -5x² +10x+7600)
y'=-10x+10x
set y'=0
-10x+10=0
10x=10
x=10/10
x=1
Maximum Rate =40+x
=40+1
=41 Dollars/Day
Maximum Income is
y= ( -5x² +10x+7600)
=(−5(1)²+10(1)+7600)
=−5(1)+10+7600

Find the median, mean, mode, and range of the data.
Answer:
median:11
mode:11
mean:11.143
range:
Step-by-step explanation:
median is the middle number so you first arrange the numbers in an ascending order after rounding off each number. Then you're gonna cancel one number from the left and one from the right until they remain two numbers then you add them and divide by 2 to get 11
I'm not sure about mode coz it's the most repeated number
mean is where you add all numbers and divide them by the total amount of numbers.
I tried!
What is the median number of 135, 122, 108, 127, 116, 76
Answer:
119
Step-by-step explanation:
76,108,116,122,127,135
if you cross them out you are left with 116 and 122, when you have 2 numbers you add them together then divide by 2 so that would give 119
hope this works :)
