Answer:
Missing side = 12.04mi /√145mi.
Step-by-step explanation:
<h3>Given :- </h3>
Perpendicular = 9 mi
Base = 8 mi
And Hypotenuse = missing side = x
<h3>Solution :- </h3>
Now substitute the values
➟ ( 9 mi ) ² + ( 8 mi ) ² = x²
Simplify the values
➟ 81 mi ² + 64 mi ² = x ²
Add the values
➟ 145 mi ² = x ²
Finding , the root of 145 mi ²
➟ √145 mi ² = x
➟ 12.04 mi = x
Therefore, The missing side of the triangle is 12.04 mi / √145 mi.
I would but I can’t see the picture I don’t know why... what is the question please type it ,thank you
Answer:
No her calculations do not make sense because the area of the smaller walls together is 234 and not 244 the total square feet of the windows and doors are also wrong. She should also subtract the doors and windows from the total so she doesn't over spend on paint. Her answer is correct just the way of finding it is wrong.
Step-by-step explanation:
Walls total sqft: (2(13ft)(9ft))+(2(16ft)(9ft))=234ft²+288ft²=522ft²
Doors+Windows total sqft: ((2(20ft)+(2(15ft))=60ft²+30ft²=90ft²
Total amount of paint needed: 522ft²-90ft²=432ft²
Amount of gallons needed remains the same
Hopefully this makes sense.

Step-by-step explanation:
It would be easier to just show you.
Because we're using variables, I'm going to plug in a random set of numbers to stand for x and y.
(x+y)^2
(2+4)^2=36
vs.
x^2+y^2
2^2+4^2=20
The difference is because, following the order of operations, in the first situation you must first take care of what is in the parenthesis, which means you add x and y together-then you multiply that combined number by the 2nd power. Whereas in the second situation, you multiply x and y by the 2nd power separately, and then add the product of that together. So opposite order. In the first situation you add, then multiply. In the second, you multiply then add.
Answer:
Constant of proportionality
K= 16.5 gallons per minute
Step-by-step explanation:
Time t (minutes) Water g (gallons)
For t= 1, g= 16.50,
for t= 1.5 ,g= 24.75
For t= 2,g= 33
Let the function be
Gallons g= k(time t)
Where k is the constant of proportionality
16.5= k(1)....for when t= 1
24.75= k(1.5) ..for when t= 1.5
Solving gives
8.25=k(0.5)
8.25/0.5= k.
16.5 = k
K= 16.5 gallons per minute
