Right triangle means Pythagorean theorem!
a^2+b^2=c^2
if each leg (a and b) = x, then
x^2+x^2=c^2
2x^2=c^2
solving for c by taking the square root of both sides leaves

c=x×sqrt(2)

c must be positive since its a length, so no need for a +- I. this case

How to do the problem
SpyIntel [72]
The top and sides of the cylinder have an area of pr^2+2prh, but the pr^2 of the top is also removed from the cube which has an area of 6s^2.

A=6s^2+2prh

A=6*36+2p4*1

A=216+8p in^2

A≈241.13 in^2 (to nearest one-hundredth)

Note that I did not include the area of the cylinder that touches the cube...

xeze [42]
So we are given that he ordered a $15 meal
now we need to find how much will he have to pay with tax and tip

so first we find the sales tax of the meal
5% * 15 = 3/4 or 0.75
and the tip
15% * 15 = 9/4 or 2.25

we will add that to the meal price to find the total
15 + 2.25 + 0.75 
total is 18
So <span>If Allam ordered a $15 meal, we will have to pay $18 with tax and tip
</span>
Hope this helps :)

A quadratic equation is written in four equivalent forms below.
____ [38]
IV is the most useful (even though all will work)
To find the y-intercept, take x=0 and substitute it into the equations.

We can see that if x=0, you can very easily observe that option IV reduces to
y = 0 + 0 - 24 = -24.
Hence (0,-24) is the y-intercept
