An airplane leaves the ground in Seattle at 11:23PM on Tuesday and lands in San Francisco 1AM. Compute the average speed of the plane while it is in the air. Express your answer in meters per second to appropriate precision (pay attention to significant figures), SHOW YOUR WORK.
Answer:
223.34 m/s
Step-by-step explanation:
Given :
Travel time = 11 :23 pm to 1:00 a. M = 1 hour 37 minutes = (60 + 37) = 97 minutes = (97 * 60) = 5820 seconds
Distance between Seattle and San Francisco is
807.7 miles (culled from the internet)
807.7 miles = 1299867.1 meters
Average speed = Distance covered / Time taken
Average speed = 1299867.1 m / 5820 s
Average speed = 223.34486
Average speed = 223.34 m/s

A triangle has side lengths of ( 5.9 k + 9.3 m ) (5.9k+9.3m) centimeters, ( 3.6 k − 3.9 n ) (3.6k−3.9n) centimeters, and ( 3.5 n + 3.4 m ) (3.5n+3.4m) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
(9.5k + 12.7m -0.4n) cm
Step-by-step explanation:
(5.9k+9.3m) + (3.6k−3.9n) + (3.5n+3.4m) = 9.5k + 12.7m -0.4n
SOMEONE PLEASE HELP!!
Answer:
C, 60 degrees
Step-by-step explanation:
Since "8" is the largest length on the triangle, that must mean that 90 degrees is the largest angle of the triangle. Plus, we know that whenever an angle is 90 degrees, no other measure of the triangle can be < 90 degrees. Therefore the answer cannot be B. Since "8" and "7" are very close (7 and x are a "pair" just like 8 and 90 degrees were), we can guess that x must be relatively close to 90 degrees. Therefore the closest answer to 90 degrees without being greater than 90 is C, 60 degrees.

A flag pole 18 feet tall casts a shadow 12 feet long at a specific time of day. Find, to the nearest degree, the angle of elevation of the sun at this time of day.
Answer:
56°
Step-by-step explanation:
Given that:
Height of flagpole = 18
Length of shadow = 12
The angle of elevation of tbe sun at the time of the day = θ
Uding trigonometry :
Tanθ = opposite / Adjacent
Tan θ = height of flagpole / length of shadow
Tan θ = 18 / 12
Tan θ = 1.5
θ = tan^-1 (1.5)
θ = 56.309
θ = 56° (nearest degree)

Answer: m=13
Step-by-step explanation:
Basically you solve this by finding out what plus 4 equals 17. You can do this by subtracting 4 from 17.
17-4=13
This is how you find the value of m.
Answer:
13!
Step-by-step explanation:
first subtract 4 on both sides!
m+4=17
m+4-4=17-4

A school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping. How much did they make selling balloons?
Answer:
OMG, Nickkkkk. It's Nyla from your 3rd block math classs. Lol, I literally looked up this question with no luck of an answer.
Step-by-step explanation:
The school club made $298.08 by selling the balloons.
What is Profit?Profit is calculated as total revenue less total expenses.
Given that, a school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping.
Cost of balloons when they brought them = 1.29*150 = $193.5
Total cost = $193.5 + (shipping price) = $193.5 + $8.92
Total cost = $202.42
Cost at which they sold the balloons = 143*$3.50 = $500.5
Therefore, their total profit = $500.5 - $202.42 = $298.08
Hence, The school club made $298.08 by selling the balloons

A group pre-orders 12 tickets for a sightseeing tour, even though they don't have the money to pay for them yet. Each ticket costs $32, so the debt for one ticket is -$32. The tour company adds a $20 fee for the entire order. Including the fee, which number represents the total debt?
Answer:
oh so you have -32 and you add 20 as the fee and your answer should be -12 I hope
helped or got it right
Step-by-step explanation:

Answer:-404
Step-by-step explanation: you take -32 for each person so -32x12 then -20 for a one time fee that’s -32x12-20 gives you -404
coffee maker has the shape of a cone 10cm high with a radius of 6 cm at the top. The coffee maker is filled with water, and the water is allowed to drain out the bottom of the cone. Water is flowing out of the filter at a rate of 5 cubic centimerters per second. At what rate is the water level in the cone falling when it is 5cm from the bottom of the cone.
Answer: the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec
Step-by-step explanation:
Given the data in the question;
H/h = R/r
10/5 = 6/r
r 1 = 30/10 = 3
Also
10/h = 6/r
r2 = 6h/10 = 3/5 × h
Volume = 1/3πr²h
V = 1/3 × π × (3/5 × h)² × h
V = 1/3 × π × 9/25 × h³
V = 3π/25 × h³
Now
dv/dt = 3π/25 × 3 × h² × dh/dt
-5 = 3π/25 × 3 × 25 × dh/dt
-5 = 3π × 3 × dh/dt
-5 = 9π × dh/dt
dh/dt = -5/9π
dh/dt = -0.1768 cm/sec
therefore, the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec

Sheldon and Leonard are partners in a business. Sheldon makes $2 in profits for every $5 that Leonard makes. If Leonard makes $20 profit on the first item they sell, how much profit does Sheldon make?
Sheldon makes a profit of $8.
What profit share ratio?The ratio of profit share in a partnership is always constant irrespective of the amount of profit.
Given,
Sheldon makes $2 in profits for every $5 that Leonard makes.
Therefore, ratio of profits of Sheldon and Leonard is 2/5.
If Leonard makes profit of $20
Then, Sheldon's profit / Leonard's profit = 2/5
Sheldon's profit / 20 = 2/5
Sheldon's profit = $8
Hence, Sheldon makes a profit of $8 If Leonard makes $20 profit.

Answer:
Step-by-step explanation:
2) x - y = 2/3
[tex]x = \frac{2}{3} + y[/tex]
3) 3x +2y = 6
3x = 6 - 2y
Divide the equation by 3
[tex]\frac{3x}{3}=\frac{6}{3}-\frac{2y}{3}\\\\x = 2 - \frac{2}{3}y[/tex]
4)
[tex]\frac{1}{4}x + y = 2\\\\ y = 2 - \frac{1}{4}x[/tex]
5) 4x - 3y = -33
-3y = -33 - 4x
Divide the equation by (-3)
[tex]\frac{-3}{-3}y=\frac{-33}{-3} - \frac{4}{-3}x\\\\ y = 11 + \frac{4}{3}x[/tex]
1) Yes, it was easy to solve one variable in terms of the other.
2) Yes, it was easy to solve for y in terms of x. Coefficient of x was a fraction.
3) It will be easy if we take the value of x as multiples of 3
Example: if x = 3,
[tex]y = 11 + \frac{4}{3}*3 \\\\y = 11 + 4\\\\y = 15[/tex]
It is easy to plot (3 ,15)
Does anyone know the value of x and y?!?!
Answer:
x=4 and y=2
Step-by-step explanation:
I'm not 100% sure but I substituted different numbers into the equation:
If x=4 and y=2 then 4+2=6 and 3x2=6 so it would be 6=6
Another option is x=7 and y=3 then 7+2=9 and 3x3=9 so it would be 9=9
I'm more confident with x=4 and y=2 because of the small size of the triangle.
I hope this helps! Good luck! :)
