Answer:
Hello! answer: 65
Step-by-step explanation:
60 × 60 = 3600
25 × 25 = 625
3600 + 625 = 4225
√4225 = 65
65 × 65 = 4225 therefore c = 65 Hope that helps!
Get multi calculator you can scan those problems and it gives you the awnser
From inspecting the graph, you can identify the y-intercept and the slope of the line shown.
The y-intercept is 200 gallons.
The slope is
75-200
m = ------------- = -12.5 gallons/minute
10 - 0
Thus, y = 200 gallons - [12.5 gallons/minute ]t
To answer the 2nd question, let t = 12 minutes and calculate y(12).
To determine how long it wld take to empty the tank, set the above formula equal to zero and solve the resulting equation for t.
There is a way to work it out with a pencil and paper, but that's too complicated
to try and explain with only text, like we have here.
I don't usually recommend this for things that can be done easily on paper ...
but for square roots, your best bet is to use a calculator.
The square root of 30 does not come out even. It starts out 5.477225...
and it keeps going and never ends.
The negative of 5.477225... is also a square root of 30. Every number has
two square roots ... the positive and negative of the same number.
the length of the side of this square is 
cm
Answer:
Solutions Given:
let diagonal of square be AC: 8 cm
let each side be a.
As diagonal bisect square.
let it forms right angled triangle ABC .
Where diagonal AC is hypotenuse and a is their opposite side and base.
By using Pythagoras law
hypotenuse ²=opposite side²+base side²
8²=a²+a²
64=2a²
a²=
a²=32
doing square root on both side
a=±
a=±2*2
Since side of square is always positive so
a=4 or 5.65 cm
