Answer:
n= 5 4/5
Step-by-step explanation:
3 1/5+5 4/5=9
The formula for finding the surface area of a sphere is A=4π

. Since we already have the radius, we just plug that into the equation, like so:
A = 4 x 3.14 x 
First, following the rules of PEMDAS, do the exponent, coming out with an answer of 1. Now, multiply 4 x 3.14, which is 12.56. 12.56 x 1 = 12.56.
Rounded to the nearest tenth, your answer is
12.6.
Hope this helps!
Well if it h then take the y key and mil in storage for you to do :)
Answer:
Let x = the charge in 1st city before taxes
Let y = the charge in 2nd city before taxes
Set up equation before taxes.
y = x - 1500 eq1
Set up equation for total tax paid.
0.065x + 0.06y = 378.75 eq2
Substitute eq1 into eq2.
0.065x + 0.06(x - 1500) = 378.75
0.065x + 0.06x - 90 = 378.75
0.125x - 90 = 378.75
0.125x = 468.75
x = 3750
Substitute this value of x into eq1.
y = 3750 - 1500
y = 2250
The hotel charge in city one is $3750 and the hotel charge in city two is $2250
