Between 10 P.M. and 7:45 A.M., the water level in a swimming pool decreased by 3/8 inches . Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?
Answer:
0.03846154... inches/hour
Step-by-step explanation:
between 10 P.M. and 7:45 A.M. = 9.75 hours
(3/8) inches / 9.75 hours = 0.03846154... inches per hour
EDIT: in fraction form
Answer:
1/26 inches/hour
Step-by-step explanation:
between 10 P.M. and 7:45 A.M. = 9 and 3/4 hours, or 39/4 hours
(3/8) inches / (39/4) hours = 1/26 inches per hour

Solve for x. What is the value of
Pls help me
Answer
x = 21
HOS = 68
Explanation
The arrows beside x point to 12 and 6, which is a straight angle. Straight angles always add up to 180 degrees.
So that means 3x+5 plus 5x+7 must equal 180 degrees.
3x+5+5x+7 = 180
Combine like terms.
8x+12 = 180
Subtract 12 from both sides.
8x = 168
x = 21
But BE CAREFUL.
The problem is asking for the angle HOS.
To do this, just substitute what you got for x into the expression.
3(21)+5 = 68
The value of HOS is 68 degrees.

Solve the equation 52 - 3.5y - 4y = 4y + 6.
Answer:
5.04
Step-by-step explanation:
=> 52 -3.5y -4y = 4y -6
Take everything with y to left and numbers to right
=> -3.5y -4y -4y = -52 -6
=> -11.5y = -58
=> 11.5 y = 58
=> y = 58/11,5= 5.04

Coach Jump is standing on a platform watching the football team practice. If the platform is 12 feet high and the quarterback is standing 23 feet from the base of the platform, find the angle of depression from Coach Jump to the quarterback. Round to the nearest degree.
Answer:
62 degrees.
Step-by-step explanation:
What you will have here is a right triangle. For the vertical put 12 ft and for the horizontal put 23 ft. You are trying to find the angle between the verticle and hypotenuse. This is what tangent is used for since you know the opposite and you know the adjacent lengths.
But since you are trying to find the angle you need to do an inverse tangent (also called arctangent)
ArctanФ = Adj/opposite
ArctanФ = 12/23 = 27.47 degrees. Rounded to the nearest degree is 27 degrees, if it wants rounded up its 28 degrees.
The angle of depression from Coach Jump to the quarterback is 27.6°.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
In this diagram,
C represents Coach Jump,
B represents the base of the platform,
θ represents the angle of depression from Coach Jump to the quarterback.
Now,
We want to find θ.
We can use the tangent function,
So,
tan Ф = 12/23
Ф = [tex]tan^{-1}[/tex] 12/23
Ф = 27.55°.
Thus,
The angle of depression from Coach Jump to the quarterback is 27.6°.

Evaluate (y - 9) + (3 + x), when y = 15 and x = 5
Answer:
14
Step-by-step explanation:
It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5'.
So we'd put 15 in y's place. It'll look like this (15 - 9).
Then we'd put 5 in x's place. It'll look like this (3 + 5).
You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!

75% of 48 show all the work
Answer:
36
Step-by-step explanation:
75%=0.75
0.75*48=3/4*48=144/4=36
Answer:
75% of 48 is 36.
Step-by-step explanation:
So, what I did here was to first find out what 25% of 48 is, because 75% is 25% multiplied by 3.
50% of 48 = 24
Since 25% is half of 50% all we have to do is divide by 2.
24 ÷ 2 = 12.
Now, we multiply by 3.
12 * 3 = 36
So, the answer is 36.
Hope this helps! :)

what factors you think determines more earthquakes will occur in an area
Answer:
Ground shaking is the primary cause of earthquake damage to man-made structures. Many factors influence the strength of earthquake shaking at a site including the earthquake's magnitude, the site's proximity to the fault, the local geology, and the soil type.
The places on the planet where one plate meets another are the most prone to earthquakes. The specific surfaces where parcels of earth slip past each other are called faults. As plates move, pressure builds up across their boundaries, while friction holds them in place
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
Why is the product of 9s diagonal?
Answer:
. With each 9s fact you add another 9, which means you go straight down a row and back one space. This creates a diagonal pattern in the grid.
Step-by-step explanation:
The number 99 is divisible by 9 . The number 999 is divisible by 9 , and so on. Any number that is a string of nines is divisible by 9 as it is 9 multiplied by a string of ones. This adds one to the sum of its digits, but you wind up with a number one more than a multiple of 9.

Dan spent a total of $25 at the grocery store. Of this amount, he spent 14 on fruit. What percentage of the total did he spend on fruit?
Answer:
56%
Step-by-step explanation:
This is because the question you need to ask yourself is: 14 is what percent of 25? and the way you solve that is making it 14/25 and then all percents are out of 100 so you need to change the fraction to over 100 so just multiply by 4 (because 25 x 4 is 100) and you get 56/100, which means 56%.
