What is the volume of a hemisphere shaped coffee if the width of the coffee cup is about 16.51 cm (use 3.14 for pie)

1177.58
2355.16
18,841.25
12,850.80

Answers

Answer:

A. 1,177.58 cm³

Step-by-step explanation:

Volume of hemisphere = ⅔πr³

Radius (r) = 16.51 ÷ 2 = 8.255

π = 3.14

Plug in the values

Volume of the hemisphere-shaped cup = ⅔ × 3.14 × 8.255³

= 1,177.57783 ≈ 1,177.58 cm³

1. Addie, Namanda, and Taylor can paint a room together in 6 hours. If Addie and Namanda could do it in 10 hours, how long would it take Taylor by herself?​

Answers

Answer:

15 hours

Step-by-step explanation:

A+N=10

(1/A+N)=1/10

(1/A+N) + (1/T)= 1/6

1/T= 1/6-1/10

1/T= (5-3)/30 = 2/30 = 15

It will take Taylor alone 15 hours to complete the work alone.

What is function?

A function is a relation between a dependent and independent variable.

Mathematically, we can write → y = f(x) = ax + b.

Given is that Addie, Namanda, and Taylor can paint a room together in 6 hours. Addie and Namanda could do it in 10 hours.

We can write that Addie, Namanda, and Taylor's 1 hour work as (1/6).

Addie and Namanda's 1 hour work = 1/10

So -

1/A + 1/N + 1/T = 1/6

1/A + 1/N = 1/10

Now -

1/T = 1/6 - 1/10

1/T = 10/60 - 6/60

1/T = 4/60

T = 60/4

T = 15 hours

 

Therefore, it will take Taylor alone 15 hours to complete the work alone.

Answer:

a is 31 b is 38 x is 133. Y is 47

Step-by-step explanation:

A is 31 because the other side is 31. we know the sides are the same because of the markings. B is 38 because the other side is 38 we know that because of the markings which mean its the same. X is 133 Y should be 47 because ALL ANGLES IN A QUADRILATERAL IS EQUAL TO 360. 133+133=266 360-266 is 94. 94 is for both angles so we need to divide by 2 the answer for Y is 47

The equation relating the number of customized cell phones produced and the profit per cell phone is p=-2.50n2+21n, where n is in 100000s. Plot the resulting graph. Be sure to label and number the axes appropriately and indicate the maximum value of p

Answers

Answer:

Please find attached the graph of the profit function created wit Microsoft Excel

The maximum profit, p[tex]_{max}[/tex] = 4,410,000

Step-by-step explanation:

The given equation is presented as follows;

The profit, p = -2.5·n² + 21·n

The value of n is given in 100,000 s

Differentiating the profit function and equating the result to zero to find the values for the maximum profit, we have;

d(-2.5·n² + 21·n)/dn = -5·n + 21 = 0

n = 21/5 = 4.2

The maximum profit, f(4.2) = -2.5 × 4.2² + 21 × 4.2 = 44.1

The maximum profit, f(4.2) = 44.1 × 100,000 = 4,410,000

What is the total amount of interest using simple interest given the following: Principal: $20,000 Interest rate: 12% Time: 10 Months

Answers

Answer:

Amount = $22000

Step-by-step explanation:

Amount = Principal + Interest

Get the interest

Interest = PRT/100

Interest = 20,000*12*10/12*100

Interest = 200 * 10

Interest = $2000

Amount  = $20,000 + $2000

Amount = $22000

a bag of potato chips states that it weight is 5 2/3 oz the maximum measurement error is -+2/5 oz . write an absolute value inequality that represents the range for the weight, x, of the bag of chips​

Answers

Answer: I (5 + 2/3) oz - xI ≤ 2/5 oz.

Step-by-step explanation:

If we have a mean M, and a measurement error e, then the absolute value inequality that represents the possible values of x, the variable, is:

IM - xI ≤ e

This means that x can be, at maximum, at a "distance" e from M.

In this case, we know that the mean weight is (5 + 2/3) oz, and the error is +- 2/5 oz, then the absolute value inequality that represents this situation is:

I (5 + 2/3) oz - xI ≤ 2/5 oz.

The first second and fourth terms of a proportion are 6, 18 and 25 respectively. Find
its third term.​

Answers

Answer:

The third term is 25/3

Explanation:

According to the given proportion,

→ First term : second term : : third term : fourth

→ 6 : 18 : : third term : 25

→ 6/18 = third term/25

→ 6*25/18 = third term [multiplying both sides by 25]

→ 1*25/3 = third term

→ 25/3 = third term.

What is the source talking about? Is it post-war population increase?Source: Carey McWilliams, Watch the West Coast, The Nation, September 1944.A spectacular population increase has accompanied the west coasts industrial revolution. The Portland metropolitan area showed a 31 per cent increase in population since 1940; the Seattle area shows an increase in population for the same period of 200,000; and an estimated 1,500,000 people have entered California since 1940. Since most industrial activity on the west coast is confined to the manufacture of aircraft and the construction of ships, sharp curtailment of employment is threatened in the post-war period. With a population increase of 14 per cent, California, for example, faces the problem of shifting 1,500,000 workers from war activities to civilian jobs after the war. . . .The typical white defense migrant is a young man, twenty-five years of age or younger, married, from a small town or rural area in the Pacific Northwest, anxious to settle in the area, and primarily interested in industrial employment in the post-war period. A study made recently in the Kaiser yards in Portland indicates that only 23.6 per cent of the migrants expressed a definite intention to leave after the war; that only a very few have maintained economic ties elsewhere or have jobs to which they might return; that considerable numbers have purchased property in the area; that a majority have their families with them; and that 86 per cent must find new employment immediately after their present employment terminates.
