hope this helps

Answer:942.48cm³

We are given the following in the question:

Dimensions of paperweight :

Radius, r = 10 cm

Height,h = 9 cm

Volume of paper weight = Volume of cone

where r is the radius and h is the height of the cone.

Putting values, we get,

Thus, the volume of the paper weight is 942.8 cubic cm.

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Answers

Answer:

8 38/45 inches

Step-by-step explanation:

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Let us represent:

Length of regular size chocolate bar = x

Length of king size chocolate bar = y

A regular size chocolate bar is 5 and 4/9 inches long.

x = 5 4/9 inches

If the king size bar is 3 and 2/5 inches longer,

Hence:

y = x + 3 2/5 inches

The length of the king size bar is calculated as:

5 4/9 inches + 3 2/5 inches

(5 + 3) + ( 4/9 + 2/5)

Lowest common denominator = 45

8 + (20 + 18/45)

8 38/45 inches

Na casa de Isabel, a leitura do hidrômetro, feita no dia 20 de março, indicava 2431 metros cúbicos. Uma nova leitura, feita um mês depois, indicou 2 590 metros cúbicos. Quantos metros cúbicos de água Isabel e seus familiares consumiram nesse período?

Answers

Answer:

159 metros cúbicos

Step-by-step explanation:

Os metros cúbicos de água que Isabel e sua família consumiram durante este período são calculados como:

Nova leitura - primeira leitura

Primeira leitura = 2.431 metros cúbicos

Nova leitura = 2590 metros cúbicos

Conseqüentemente:

2.590 metros cúbicos - 2.431 metros cúbicos

= 159 metros cúbicos

You see how y=4x and the left side on the table is x and the right side is y you plug whatever number is on the x side into the -4x
For example let’s do the first one y=-4(9) -4 multiplied by 9 is 36 so y=36 so you put 36 in the first box on the right (y side)

Answer:

1) (-36)

2) 4

3) (-4)

4) (-20)

5) (-12)

Step-by-step explanation:

See, above it written that y = (-4)x

Then below they are giving the value of x

So, according to that we have to solve the value y

For example:

y = (-4) x 9

y = (-36)

The test scores of 8 students are shown in the table above. Let m be the mean of the scores and M be the median of the score. What is the value of M-m?

Answers

Answer:

Step-by-step explanation:

Both M and m equal 81

The resultant value of the difference of Median and Mean will be 0.

Define Mean, Median and Mode for a given set of data.

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

The median is the middle value when a data set is ordered from least to greatest.

The mode is the number that occurs most often in a data set.

Given is the test scores of 8 students are shown in the table.

We can write the data in the order least to greatest as -

67, 75, 75, 75, 87, 87, 91, 91

Mean = 648/8 = 81

Median = (75 + 87)/2 = 81

So, we can write (Median- Mean) as 81 - 81 = 0

Therefore, the resultant value of the difference of Median and Mean will be 0.

At 11:45 A.M. Jason glanced at the clock. His doctor's appointment was in 2 ½ hours. At what time was his appointment

Answers

Answer:

14 : 15 or 2 : 15 pm

Step-by-step explanation:

Time of the appointment = 11: 45 + 2 ½ hours

Jason's appointment is in 2 ½ hours. His appointment is in 2 hours + 1/2 of an hour

1/2 of an hour = 1/2 x 60 = 30 minutes

Remember that 60 minutes make one hour

Time of the appointment = 11:45 + 2:30

[tex]11 : 45[/tex]

+ 2 : 30

13 : 75

we would have to adjust the time derived from the addition because the maximum minutes that exist is 60

To adjust, remove 60 minutes from the minutes and add it to the hour

this gives 14 : 15 or 2 : 15 pm
