Answer:
314 mi^2 (3 s.f.)
Step-by-step explanation:

diameter of sphere= 10mi
radius of sphere= 10÷2= 5mi
Surface area of sphere= 4(pi)(5^2)= 100pi= 314mi^2 (3 s.f.)
It is convenient to let a spreadsheet or graphing calculator do the math for this. Functions can be defined for cost and profit, and evaluated at each of the volumes of interest.
a1) For 200 cars, the Outside location yields the greatest profit
a2) For 300 cars, the City location yields the greatest profit
b) The sites yield the same profit for a volume of 278 cars.
Answer: Z> -17
z/2+26=17.5
We move all terms containing z to the left and all other terms to the right.
+ 0.5z=+17.5-26
We simplify left and right side of the equation.
+ 0.5z=-8.5
We divide both sides of the equation by 0.5 to get z.
z=-17

Answer:
Step-by-step explanation:
1.
Find value of P that makes this true
4p-5=`9
Solve for P by isolating it on one side:
4p-5+5=9+5
4p/4=14/4
P=3.5
2.
Translate the Algebraic Expression:
A waiter earns $128 for 6 hours of work including $86 of tips.
Subtract tips from total:
128-86=42
Divide Value between hours.
42/6=7
$7 per hour
3.
Find the Value of X that makes this true
-4x+26=-2
Solve for X by isolating it on one side:
-4x+26-26=-2-26
-4x/-4=-28/-4
X=7
4.
What is the first correct step in solving the equation:
33-2x=31
Subtract 33 from both sides
