$\frac{\sqrt{9x^2}}{\sqrt{18y^2}}=\frac{x\sqrt{3^2}}{y\sqrt{3^2*2}}=\frac{\not3x}{\not3y\sqrt2}=\frac{x}{y\sqrt2}=\frac{x}{y\sqrt2}*\frac{\sqrt2}{\sqrt2}=\frac{x\sqrt2}{2y}$
Answer = C

A small-appliance manufacturer finds that the profit P (in dollars) generated by producing x microwave ovens per week is given b

Olegator [25]

Answer:

Number of ovens must be manufactured in a given week to generate a profit of $1610 is 70

Step-by-step explanation:

We are given

A small-appliance manufacturer finds that the profit P (in dollars) generated by producing x microwave ovens per week is given by the formula

$P=\frac{1}{10}x(300-x)$

provided that 0 ≤ x ≤ 200

We are given

profit is $1610

so, we can set P=1610

and then we can solve for x

$1610=\frac{1}{10}x(300-x)$

Multiply both sides by 10

$1610\cdot \:10=\frac{1}{10}x\left(300-x\right)\cdot \:10$

$16100=x\left(300-x\right)$

$16100=300x-x^2$

$-x^2+300x-16100=0$

now, we can factor it

$(x-70)(x-230)=0$

we can solve for x

and we get

$x=70,x=230$

Since, x=230 does not lie on 0 ≤ x ≤ 200

So, we will consider only x=70

So,

Number of ovens must be manufactured in a given week to generate a profit of $1610 is 70

A rectangular classroom has an area of 300 square feet. The length of the classroom is 5 feet longer than the width, w. Create a

weqwewe [10]

Answer:

w^2 + 5w = 300

Step-by-step explanation:

A= length x width

A =300

Width = w

length = w + 5

Therefore

300 = (w) x (w + 5)

300 = w^2 + 5w

w^2 + 5w = 300

If beginning inventory at cost was $12,000.00, ending inventory at cost $10,4000.00, and the cost of goods sold $18,000.00, what

RoseWind [281]

Inventory turnover is
Cost of goods sold divided by the average merchandise inventory

First we should find the average merchandise inventory
Add the inventory on hand at the start of the year to the inventory on hand at the end of the year and divide the result by 2 to find the company's average inventory
(12,000+10,400)÷2=11,200

Now find the inventory turnover
Divide the company's cost of goods sold for the year by the average inventory to figure the company's inventory turnovers per year.
18,000÷11,200=1.61.....answer

Hope it helps
