A paper drinking cup in the shape of a cone has a heightof 10 centimeters and a diameter of 8 centimeters.

Which of the following is closest to the volume
of the cup in cubic centimeters?

27 cm
53 cm
80 cm
160 cm

Answers

Answer 1
Answer:

The solution is, 160 cm is closest to the volume of the cup in cubic centimeters.

What is volume of cone ?

The formula for the volume of a cone is ⅓ r2h cubic units, where r is the radius of the circular base and h is the height of the cone.

here, we have,

a cone has a height of 10 centimeters

and a diameter of 8 centimeters.

so, we know,

Volume =  ⅓ r²h

i.e. V = 167.55

Hence, 160 cm is closest to the volume of the cup in cubic centimeters.

Answer 2
Answer:

Answer:

I am pretty sure it is 53cm.

Step-by-step explanation:

If it were in a cylinder shape 10 x 8 is 80 but is is in the shape of a cone so the volume lessens so it can't be 80cm or 160cm. 27cm is a bit to low so that is why I am 90% sure it is 53cm.

The cost of a watermelon depends on its weight which of the following shows this idea expressed in function notation A: weight(cost)

B: cost(watermelon)

C: cost(weight)

D: weight (watermelon)

Answers

Answer:

Option C is correct.

Step-by-step explanation:

The general form for writing a function of x is f(x) where f depends on value of x.

Here, in the given options, Option C is correct as weight is a function for cost. The cost depends on the weight. The more the weight of the watermelon, the more its cost. So, C: cost(weight) is correct.

Options B and D are irrelevant and option A is also wrong as it signifies that weight depends on cost which is wrong.

That would be choice C, cost as a function of weight.


Answer: C

Given f(x)=x^2-8 and g(x)=x+1/x, find (g o f)(1)[Hint:(g o f)(-4)=(g(f(-4))]
a.)8/7 b.)8 c.)6/7 d.)-8

Answers

f(1) is equal to 1^2-8, or -7.

g(x) is (-7+1)/-7, or -6/-7.  This simplifies to 6/7.  C is the best option.

Also, since you posted a similar question earlier, I knew what to look for with g(x), but in the future, this looks like the x is not divided by the x in the denominator, and you should express this function as (x+1)/x to increase clarity.

Angelica had two jobs last year, and she received two W-2 forms. On the first W-2 form, the figure in box 1 was $13,638.26, while on the second W-2 form, the figure in box 1 was $8791.42. What was Angelica's gross income from the two jobs last year?A.$11,214.84
B.$5607.42
C.$4846.84
D.$22,429.68

Answers

Angelica's gross income from the two jobs for the last year is $22,429.68. 

You would get this by adding $13,638.26 + $8,791.42 = $22,429.68. 

The correct answer is D. 

Answer:

Angelica's gross income from the two jobs last year is $22,429.68

Step-by-step explanation:

Angelica had two jobs last year, and she received two W-2 forms.

On the first W-2 form, the figure in box 1 was $13,638.26,

while on the second W-2 form, the figure in box 1 was $8791.42.

Income from first job is $13,638.26

Income from second job is $8791.42

Total income = first job income + second job income

=13638.26 + 8791.42 = 22,429.68

Angelica's gross income from the two jobs last year is $22,429.68
