Answer:

Step-by-step explanation:

The surface area is the area of all the surfaces. The surface area of cylinder has the formula:

$SA_{cyl}=2\pi r^2 +2\pi rh$

Where

r is radius

h is height

r is 8

h is 3

Substituting, and keeping $\pi$ as is, we have:

$SA_{cyl}=2\pi r^2 +2\pi rh\\SA_{cyl}=2\pi (8)^2 +2\pi (8)(3)\\SA_{cyl}=128\pi +48\pi\\SA_{cyl}=176\pi$

Thus,

Surface Area = $176\pi$ units squared, answer choice D is right

Goods available for sale are $40000, beginning inventory is $16000, ending inventory is $20000, the cost of goods sold $50000, w

zlopas [31]

Answer:

Step-by-step explanation:

Inventory turn over is the same as the inventory turn over ratio. Inventory turn over is defined simply as the ratio of the cost of goods that was sold (net sales) to the average inventory at the selling price.

Inventory turn over = Cost of goods/average inventory

Cost of goods sold = $50000

Average inventory = beginning of inventory + ending inventory/2

Average inventory = $16000+$20000/2

Average inventory = $36000/2

Average inventory = $18000

Inventory turn over = $50000/$18000

Inventory turn over= 2.78

Write 0.18 in the standard form

salantis [7]

Hello there!

Standard form is used for large or small numbers. It is between 1 and 10 times 10 to the power of something.
In this case, your answer is 1.8 x $10^{-1}$ .

Hope This Helps You!
Good Luck :)

A health food store makes trail mix using dried fruit and nuts. The cost of the dried fruit is $2.50 per

Vinil7 [7]

Answer:

cost of dried fruit per pound=2.5 $/pound

cost of nuts per pound =2 $/pound

total cost=225$ =cost of dried fruit +total cost of nuts

To find the cost of dried fruit we need to multiply cost of dried fruit per pound and the number of bounds hence 2.5 x where x is the number of bounds

which is the total cost of dried fruit and consequently 2y is total cost of nuts where y is the weight of nuts in pound

Two college roommates have each committed to donating to charity each week for the next year. The roommates’ weekly incomes are

schepotkina [342]

Answer:

C. 5 weeks.

Step-by-step explanation:

In this question we have a random variable that is equal to the sum of two normal-distributed random variables.

If we have two random variables X and Y, both normally distributed, the sum will have this properties:

$S=X+Y\\\\\ \mu_S=\mu_X+\mu_Y=30+60=90\\\\\sigma_S=\sqrt{\sigma_X^2+\sigma_Y^2}=\sqrt{10^2+20^2}=\sqrt{100+400}=\sqrt{500}=22.36$

To calculate the expected weeks that the donation exceeds $120, first we can calculate the probability of S>120:

$z=\frac{S-\mu_S}{\sigma_S} =\frac{120-90}{22.36}=\frac{30}{22.36}=1.34\\\\P(S>120)=P(z>1.34)=0.09012$

The expected weeks can be calculated as the product of the number of weeks in the year (52) and this probability:

$E=\#weeks*P(S>120)=52*0.09012=4.68$

The nearest answer is C. 5 weeks.
