Answer is the equation 9n = 18 and solved the answer is n=2

Reason
Product is multiplying so the product of a number (n) an 9 is 9n.
18 is equal to means =18.
9n = 18
To solve, divide both sides by 9
n= 2

Two sides of a triangle measure 9 cm and 23 cm what could be the measurement of the third side of the triangle
Vladimir79 [104]
Pythagorean Theorem: a^2+b^2=c^2
(9)^2 + b^2 = (23)^2
81 + b^2 = 529
b^2 = 529 - 81
b^2 = 448
b^2 =
\sqrt{448}
b = 21.2

Find the dimensions of a closed right circular cylindrical can of smallest surface area whose volume is 128pi cm^3
Ratling [72]
The surface area of a cylindrical can is equal to the sum of the area of two circles and the body of the cylinder: 2πr2 + 2πrh. volume is equal to π<span>r2h.

V = </span>π<span>r2h = 128 pi
r2h = 128 
h = 128/r2

A = </span><span>2πr2 + 2πrh
</span>A = 2πr2 + 2πr*(<span>128/r2)
</span>A = 2πr2 + 256 <span>π / r
</span><span>
the optimum dimensions is determined by taking the first derivative and equating to zero.

dA = 4 </span>πr - 256 <span>π /r2 = 0
r = 4 cm
h = 8 cm

Answer:

A h+p ≤15

50h+500p ≥ 2500

Step-by-step explanation:

h = headphone and

p = pianos

We can only ship a maximum of 15 total

h+p ≤15

We must sell  at least 2500 dollars of product.  Headphones are 50 and pianos are 500

50h+500p ≥ 2500
