Answers

Answer:

Answer: D

Step-by-step explanation:

Let's just go through it.

No parallel sides A B C (if you believe the diagram) D F

Not regular (and no parallel sides) (if you believe the diagram) B C D F

No Lines of symmetry (that means that if you put a mirror on a line of symmetry) what you see as an image will be the same as what there is in front of the mirror. C D F

Has a reflex angle. (Just to remind you, it is an angle greater that 180 but less than 360

That lets out everybody but D.

Answer: D

Step-by-step explanation:

1. C and G have one set of parallel sides, and E, H, and I have two sets of parallel sides so they can be ruled out.

2. Regular shapes have sides that are all the same length and angles that all measure the same. A can be ruled out in addition to I which was already ruled out.

3. B can be ruled out now.

4. The only one with a reflex angle (greater than 180 degrees) is D.

write 1 1/2 and 2 1/4 on the number line below.

Answers

Answer:

So lets convert the fractions to improper:

3/2 and 9/4

And for it to be easier to plot, make them decimals (divide):

1.5 and 2.25

The step here is 0.125 (1/8 (the amount of lines between a number))

Plot:

1.5, is 1 1/2 and 2.25 is 2 1/4 on the number line..

Lets convert the fractions to improper:

1 1/2 = 3/2 = 1.5.

2 1/4 = 9/4 = 2.25.

3/2 and 9/4

And for it to be easier to plot, make them decimals (divide):

1.5 and 2.25

Therefore, 1.5, is 1 1/2 and 2.25 is 2 1/4 on the number line.

What is the volume of the composite figure shown? Use 3.14 for π.

Answers

Answer:

25.12

Step-by-step explanation:

the formula of a cone is pi r^2 * h/3

r = radius and h = height

the radius is 2 and the height is 3

and the question says use 3.14 instead of pi so

we have

3.14 * 2^2 * 6/3

2*2 or 2^2 = 4

3.14 * 4 * 6/3

6/3 = 2

3.14 * 4 * 2

4*2 = 8

and 8 * 3.14 is 25.12

The answer to this question is 25.12

Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1

Answers

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

The budget wil include operating, capital, cash and flexible budgets. The hospital is noted for its three fine programs: oncology (cancer), cardiac (heart), and rhinoplasty (nose jobs).Section AThe managers at Denison have been busy working. They have reviewed past records and considered changes in competition, the general economy, and overall medical trends. Using past charges and anticipated rates of medical inflation, they have also made a first attempt at setting thier prices.Based on a thorough review and discussion of these data, they have projected that next year they will have 240 patients. They expect 120 oncology patients, 80 caridace patients, and 40 rhinoplasty patients.The charge, of list price, for oncology patient will average $50,000. Cardiac patients will be charged on average of $40,000, and rhinoplasty, $25,000 per patient. However, those charges are not the actual amounts ultimately received.The amount the hospital receives depends on whether patients pay their own hospital bills or have healthcare insurance. Assume that private insurance companies pay the full charge or list price. However, Medicare and Medicaid have announced rates they will pay for the coming year as follow: oncology patients $40,000, cardiac patients $30,000, and rhinoplasty patients $10,000. Self-pay patients are supposed to pay the full charge, but generally 25 percent of self-pay charges become a bad credit. Note that bad credit are treated as an expense in healthcare. They may not be shown as a reduction lowering revenues. The full charge for self-pay patients is shown as revenues, and then the uncollectible amount is shown as an expense. No payment for charity care is ever recieved, and charity care is not shown s a revenue or expense.The payer mix is as follows: Private insurance Medicare/Medicaid Self-Pay CharityOncology 30% 50% 10% 10%Cardiac 20% 60% 10% 10%Rhinoplasty 10% 20% 60% 10%Gift shop revenue is projected to be $120,000 for the current year and is expected to remain the same. However, this revenue will increase or decline in proportion to charges in patient volume.Denison Hospital has an endowment of $1,000,000. It is invested as follows:a-$500,000 in 6 percent U.S. Governement Bonds that pay interest annuallyb-$250,000 in AT&T stock, which pays a dividend of 8 percent annuallyc-$250,000 in growth stocks that pay no dividendSection A requirements:1. Calculate patient revenue on an accural basis for the coming year. Subdivide revenue by program, and with each program subdivide it by type of payer.2. Calculate endowment revenue on an accural basis for the coming year.3. Prepare a revenue budget on an accural basis, including all sources of revenue discussed previously. The revenue budget does not have to show all of the detail from requirements 1 and 2, but should show each major source of revenue, such as patient services and endowment.Section BThe hospital expects to employ worker in the following departments Radiology Nursing Administration TotalManagers 100,000 200,000 200,000 500,000Staff 1,900,000 4,200,000 300,000 6,400,000Total 2,000,000 4,400,000 500,000 6,900,000Supplies are expected to be purchased throughout the year for the departments, as follows: TotalRadiology 360,000Nursing 160,000Administration 20,000Total 540,000Assume that all supply use varies with the number of patients.Denison Hospital currently pays rent on its building and equipment for $300,000 per year. Rent is expected to be unchanged next year. The rent is paid $75,000 each quarter.To better serve its patients, Denison would like to buy $500,000 of new oncology equipment at the start of the year. It would be paid for immediately upon purchase. The equipment has a 5-year life and would be expected to be used up evenly over that lifetime. Although the capital budget would normally include justification for why the equipment is needed, it is sufficient for our purpose to know that the capital budget for Denison is $500,000 and the equipment to be purchased has 5-year useful life. It will have no value left at the end of the 5 years. Denison charges the cost of its capital acquisitions on a straight-line depreciation basis. The means that the cost is spread out over the useful life, with an equal being charged as an expense, called depreciation expense, each year.Section B Requirements:1. Calculate expected bad debt expenses on an accural basis for the coming year2. Calculate an expense budget on a accural basis for the coming year. The expense budget does not require detailed information by program or department, but should show each type of expense as salaries and supplies. Be sure to consider the impact of capital acquisitions on the expense budget.3. Combine the revenue (section A) and expense budget to present an operating budget for the coming year.
