Working alone it takes jull 8.4 hours to pick forty bushels of apples. Maria can pick the same amount in 15 hours.If the worked together how long would it take them
Answer: 5.39 hours
Step-by-step explanation:
For Jill:
Number of hours used = 8.4 hours
Number of bushels of apples picked = 40
Number of bushels of apples picked per hour will be: = 40/8.4 = 4.7619
For Maria:
Number of hours used = 15 hours
Number of bushels of apples picked = 40
Number of bushels of apples picked per hour will be: = 40/15 = 2.6667
We then add the number of bushels of apples picked per hour for both of them together. This will be:
= 4.7619 + 2.6667
= 7.4286
If they worked together, the hours they'll take to pick 40 bushel of apples will be:
= 40/7.4286
= 5.39 hours
A pilot needs to know if a plane with clear the tower. The plane will travel 1300 yards
before lifting off the ground to travel another 705 yards after which point the plane will
be directly over the tower. If the plane had continued on the runway, it is another 700
yards to the control tower, which is 250 feet high
Which statement best describes how to determine if the plane clears the tower?
Use the Pythagorean Theorem where the distance to the tower is a les of the right triangle and
the height of the tower is the other leg. Verity that these equal the exact distance in the air. It
not exactly the same, the plane does not clear the tower
Use the Pythagorean Theorem where the distance to the tower is a leg of the right triangle and
the distance in the air is the hypotenuse. Find the other leg. Convert to feet to compare to the
tower height
Use the Pythagorean Theorem where the distance to the tower plus the distance the plane
travels on the ground is a leg of the right triangle and the distance in the air is the hypotenuse
Find the other leg. Convert to feet to compare to the tower height
Answer:
The statement that best describes how to determine if the plane clears the tower is;
Use the Pythagoras Theorem where the distance to the tower is a leg of the right triangle and the distance in the air is the hypotenuse. Find the other leg. Convert to feet to compare to the tower height
Step-by-step explanation:
The given parameters are;
The length the plane will travel before lifting = 1300 yards
The distance further the plane will travel after lifting off the ground = 705 yards
The horizontal distance from the point of lifting off the ground to control tower = 700 yards
The distance of the path of the plane after lifting off the ground, the horizontal distance from the point of lifting off the ground to control tower and the height of the control tower form a right triangle with sides given as follows;
The distance of the path of the plane after lifting off the ground = The hypotenuse side of the triangle
The horizontal distance from the point of lifting off the ground to control tower and the height of the control tower = The two legs of the right triangle
Let h, represent the height of the control tower, let x represent the horizontal distance from the point of lifting off the ground to control tower and let R represent the distance of the path of the plane after lifting off the ground, we have;
h = √(R² - x²)
We have;
R = 705 yards
x = 700 yards
∴ h = √(R² - x²) = h = √(705² - 700²) = 5·√281
The height of the control tower, h = 5·√281 yards
1 yard = 3 feet
∴ 5·√281 yards = 3 × 5·√281 feet ≈ 251.446 feet
Therefore, given that the height of the control tower = 250 feet, the plane at the height of approximately 251.446 feet clears the tower.
The height of the control tower = 250 feet and the plane the height of approximately 251.446 feet clears the tower.
The statement that best describes how to determine if the plane clears the tower is;
Use the Pythagoras Theorem where the distance to the tower is a leg of the right triangle and the distance in the air is the hypotenuse. Find the other leg. Convert to feet to compare to the tower height
The given parameters are;
The length the plane will travel before lifting = 1300 yards
The distance further the plane will travel after lifting off the ground = 705 yards.
The horizontal distance from the point of lifting off the ground to control tower = 700 yards
The distance of the path of the plane after lifting off the ground, the horizontal distance from the point of lifting off the ground to control tower and the height of the control tower form a right triangle with sides given as follows.
The distance of the path of the plane after lifting off the ground = The hypotenuse side of the triangle.
The horizontal distance from the point of lifting off the ground to control tower and the height of the control tower = The two legs of the right triangle.
Let h, represent the height of the control tower, let x represent the horizontal distance from the point of lifting off the ground to control tower and let R represent the distance of the path of the plane after lifting off the ground, we have;
[tex]h = \sqrt{(R^2 - x^2)}[/tex]
We have given that
R = 705 yards
x = 700 yards
[tex]h = \sqrt{(R^2 - x^2)} \\ h = \sqrt{(705^2 - 700^2)}\\ h= 5\times \sqrt {281}[/tex]
The height of the control tower,[tex]h = 5 \sqrt {281}[/tex] yards.
What is the value of one yard in feet?1 yard = 3 feet
[tex]5\sqrt {281} yards= 3 \times 5\times \sqrt{281} feet \approx 251.446 feet[/tex]
Therefore, given that the height of the control tower = 250 feet, the plane at the height of approximately 251.446 feet clears the tower.

Answer:
x = 58
Step-by-step explanation:
Angle Formed by Two Secants = 1/2(difference of Intercepted Arcs)
51 =1/2 (160-x)
Multiply each side by 2
102 = 160-x
Subtract 160 from each side
102-160 = -x
-58 = -x
Multiply by -1
58 =x
Answer:
x = 58
Step-by-step explanation:
[tex]51 \degree = \frac{1}{2} (160 \degree - x \degree) \\ \\ 51 \times 2 \degree = 160 \degree - x \degree \\ \\ 102 \degree = 160 \degree - x \degree \\ \\ x \degree = 160 \degree - 102 \degree \\ \\ x \degree = 58 \degree \\ \\ \huge \red{ \boxed{x = 58}}[/tex]

You and your friend are selling magazine subscriptions for a fundraiser. After w weeks, you have sold (3w+8) subscriptions and your friend has sold (6w+6) subscriptions.
Answer:
3w-2
Step-by-step explanation:
Given that, after w weeks you sold (3w+8) subscriptions and your friend sold (6w+6) subscriptions.
So, the difference between the number of subscriptions your friend has sold and you have sold after w weeks = (6w+6)-(3w+8)
=6w+6-3w-8
=3w-2
Hence, the required expression is 3w-2.

Answer:
f(x) = (x^2+2)/(x-1)
Step-by-step explanation:
In simplest form, it will be a quadratic divided by (x-1). The quadratic must have no zeros, and a y-intercept of 2.
One such could be ...
f(x) = (x^2 +2)/(x -1)
__
The numerator polynomial must have no zeros in order to prevent the rational function from having zeros. It must be a function that has a degree an odd number greater than the denominator function. The denominator function can have only one zero, at x=1. The ratio of the functions must have a net odd degree and the overall leading coefficient must be positive in order to make the end behavior match the requirement.

find equation of straight line which
divides the line joining the points P(-1, -4) and Q (7, 1) in the ratio of 3:2 and perpendicular to it.
Answer:
The required equation is: [tex]y = -\frac{8}{5}x+\frac{127}{25}[/tex]
Step-by-step explanation:
The slope-intercept form of a line is given by:
[tex]y = mx+b[/tex]
For writing equation of a line, slope and a point is needed from which the line passes.
In order to find the slope of line perpendicular to PQ, we have to find slope of PQ first.
Slope is denoted by m and given by the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Given points are:
P(-1, -4) and Q (7, 1)
Putting the values
[tex]m = \frac{1-(-4)}{7-(-1)}\\m = \frac{1+4}{7+1} = \frac{5}{8}[/tex]
The product of slope of two pependicular lines is -1
Let m1 be the slope of line perpendicular to PQ
[tex]m.m_1 = -1\\\frac{5}{8}.m_1 = -1\\m_1 = \frac{8}{5} * -1\\m_1 = -\frac{8}{5}[/tex]
Now for the point, we have to find the point that divides PQ in ratio 3:2
The formula is:
[tex](x,y) = (\frac{nx_1+mx_2}{m+n} , \frac{ny_1+my_2}{m+n})\\[/tex]
Here
m = 3
n= 2
Putting the values
[tex](x,y) = (\frac{(2)(-1)+(3)(7)}{3+2} , \frac{(2)(-4)+(3)(1)}{3+2})\\= (\frac{-2+21}{5} , \frac{-8+3}{5})\\=(\frac{19}{5} , \frac{-5}{5})\\=(\frac{19}{5} , -1)[/tex]
So we have to write equation of a line with slope -8/5 and passing through point (19/5, -1)
Putting the values in slope-intercept form
[tex]y = -\frac{8}{5}x +b[/tex]
Putting the point in the equation
[tex]-1 = -\frac{8}{5} (\frac{19}{5}) + b\\-1 = -\frac{152}{25} + b\\b = -1+\frac{152}{25}\\b = \frac{-25+152}{25}\\b = \frac{127}{25}[/tex]
Putting the value of b
[tex]y = -\frac{8}{5}x+\frac{127}{25}[/tex]
Hence,
The required equation is: [tex]y = -\frac{8}{5}x+\frac{127}{25}[/tex]
