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)

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.

Abram and Fred leave opposite ends of a bike trail 8.5 miles apart and travel toward each other. Abram is traveling faster than Fred. Find each of their speeds if they meet after 30 minutes.
Complete question :
Abram and Fred leave opposite ends of a bike trail 8.5 miles apart and travel toward each other. Abram is traveling 3mph faster than Fred. Find each of their speeds if they meet after 30 minutes.
Answer:
Fred's speed = 7mph
Abrams speed = 7 + 3 = 10 mph
Step-by-step explanation:
Given that :
Distance apart = 8.5 miles
Let :
Fred's speed = x
Abram's speed = x + 3
Time they meet = 30 minutes = 0.5 hour
Speed = distance / time
Distance = speed * time.
Fred's distance + Abram's distance = 8.5 miles
(x * 0.5) + (x + 3)*0.5 = 8.5
0.5x + 0.5x + 1.5 = 8.5
x + 1.5 = 8.5
x = 8.5 - 1.5
x = 7 mph
Fred's speed = 7mph
Abrams speed = 7 + 3 = 10 mph

m + 4 = 17
Please help
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
simplify/subtract 17-4=13!

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! :)
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

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
8x+6x=112+1x+7x=89

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

I need help to get good grade
Answer:
scale factor: 3
Step-by-step explanation:
For this I will take both A and A' points. So A is (2,2) and A' is (6,6) and since the shape increased in size that means our scale factor must be greater than 1. So all that we have to do is know is how did we get from this x value to that x value or in other words 2 times what equals 6 and it's 3. Then we would do the same for the y value but since it would be the same 2 times what equals 6 and it's still 3 so 3 is the scale factor.

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.
