Stacie is a resident at the medical facility where you work. You are asked to chart the amount of solid food that she consumes.
katrin2010 [14]

Remark

The general formula is fraction * solid food = amount

Total amount = 1/2 * 3 oz + 3/4 * 3 oz + 1/3 * 2 oz

Total amount = 3/2 oz + (9/4) oz + 2/3 oz

The lowest common denominator of  2 4 and 3 = 12

Total amount = 3*6/2*6 + 9*3/4*3 + 2*4/3*4

Total amount = 18/12 + 27/12 + 8/12

Total amount = 53/12 = 4 5/12 <<< Answer oz of food.

4.42 oz of food <<<< Answer

kap26 [50]
Answer: Dr. Bolton was born in 1926.

Work: 

Let x be the thousands digit. So, you will have the tens digit be 2x, the ones digit be 6x, and the hundreds digit be 9x. Now, let's try x as 1. Then, you will have the thousands digit be 1, the tens digit be 2, the ones digit be 6, and the hundreds digit be 9. Hope it helps!

Simplify.<br> (c/3)^-2<br><br> A. c²/9<br> B. 9/c²<br> C. 1/9c²<br> D. 9c²
torisob [31]
The same applies to this one as well...we have a fraction of C/3 and the whole fraction has the exponent of -2.

C^-2 / 3^-2 = C^-2 / 9....we can't have a negative exponent in the numerator, so we send it to the bottom and make it a positive...

9 / C^2

Answer:

Step-by-step explanation:

Part C: (Explanation with steps)

Let the length of the swimming pool = l feet

And width of the pool = w feet

Perimeter of the pool = 2(l + w) feet

Since, perimeter of the pool = 8 feet

2(l + w) = 80

l + w = 40

l = (80 - w) -------(1)

Area of the pool = Length × width

A(w) = l × w

By substituting the value of l from equation (1)

A(w) = (80 - w) × w

A(w) = 80w - w²

To find the maximum area of the pool we will find the derivative of the function with respect to 'w' and equate it to zero.

A'(w) = 80 - 2w

(80 - 2w) = 0

w = \frac{80}{2}

w = 40 feet

Therefore, for width (w) = 40 feet area of the pool will be maximum.

From equation (1),

l = 80 - 40

l = 40 feet

Therefore, maximum area of the pool = l × w

                                                               = 40 × 40

                                                               = 1600 square feet

Part A:

Function representing area of the pool,

A(w) = -w² + 80w

Part B:

Maximum area of the surface of the pool = 1600 square feet
