Answer:

try using a graphing calculator.

Step-by-step explanation:

I know this doesn't really answer your question, but it gets you closer to the answer. Just put your problem into go-ogle, and go-ogle should spit out a graph with the answers of x and y right on it.

Answer:

Volume of a cylinder : πr^2h

: π = 22/7

: r = 9

: h = 20

: 22/7 × 9^2 × 20

: 5091.4 (corrected to 1.dp )

Answer:

  5089.4 cm³

Step-by-step explanation:

You want the volume of a cylinder with radius 9 cm and height 20 cm.

The volume of a cylinder is given by the formula ...

  V = πr²h

For r = 9 cm and h = 20 cm, the volume is ...

  V = π(9 cm)²(20 cm) = 1620π cm³

The value you get for this depends on the value you use for π. The attachment shows the three common choices: "π button", 3.14, 22/7.

Using the "pi button" value provided by a calculator, the volume is ...

  5089.4 cm³

Answer:

The state itself is 50% of the total height.

Explanation:

Well, if the height including the base is 300 ft, that'd mean the total height of the statue itself is (300-150) ft = 150 ft.

Thus, it is (150/300)*100% = 50% of the total height.

====================================================

Explanation:

The set of given numbers sorts to this

11, 50, 72, 78, 80, 81, 85, 89, 94, 96, 97, 98

The majority or main cluster of the values are between 50 and 98. The outlier 11 is off on its own pretty far from the main cluster.

Let's find the mean of every value in this set. If you added up all the numbers, then you should get 931. Divide this over the number of values (12) and the mean of this set is roughly 931/12 = 77.5833

Now let's kick out the outlier 11. The 931 will drop to 931-11 = 920. Divide that new smaller sum over the 12-1 = 11 items left to get 920/11 = 83.6364 approximately.

--------------

To summarize so far:

We see that the mean has increased. This is because the outlier was pulling down on the mean to make it smaller than it should be. Once the outlier is out of the picture, the new mean will increase and better represent the center of the main cluster.

Answer:

27. x=7/20; 28. m= 3.7; 29. a= 5.8

30. x= 6; 31.x= 46

Step-by-step explanation:

27.

[tex]x + \frac{2}{3} = \frac{9}{ 10} [/tex]

you are going to carry the 2/3 over the equal sign. This will make the 2/3 negative so...

[tex]x = \frac{9}{10} - \frac{2}{3} [/tex]

now calculate it by finding the LCM of 10 and 3 ....this will be 30....you can just multiply the 10 and 3

now

30 into 10 goes 3 times....you will multiply this 3 with the 9 to get 27

30 into 3 goes 10 times...you will multiply this 10 with the 2 to get 20

[tex]x = \frac{27 - 20}{30}[/tex]

[tex]x = \frac{7}{30} [/tex]

Hopefully you understand

28.

[tex]1.2 = m - 2.5[/tex]

[tex]1.2 + 2.5 = m[/tex]

carry the 2.5 over the equal sign to get the m by itself...this is because you are trying to find m

when the negative number goes over the equal sign it will become positive...this is why you add it to the 1.2

m= 3.7

you can do the other on your own

the error in 30 is that the 7 should not be added to the 13 but subtracted

..this is because when you carry the positive number over the equal sign it will become negative..hence you subtract it

[tex]x + 7 = 13[/tex]

[tex]x = 13 - 7[/tex]

[tex]x = 6[/tex]

and for 31...the 12 should not be subtracted but added since when it goes over the equal sign it will become positive.

[tex]34= y - 12[/tex]

[tex]34 + 12 = y[/tex]

[tex]y = 46[/tex]

Answer:

Missing denominator = 36

Step-by-step explanation:

Let us assume that,

→ Missing denominator = x

Now we have to,

→ Find the required value of x.

Forming the equation,

→ 27/x = 3/4

Then the value of x will be,

→ 27/x = 3/4

→ 27 × 4 = 3 × x

→ 108 = 3x

→ 3x = 108

→ x = 108/3

→ [ x = 36 ]

Hence, the value of x is 36.

Answer:

1/2b - 5 (the third one)

Step-by-step explanation:

"Denni is five years less..."

this tells us we will need to be subtracting five, which knocks out the other answers.

"..one-half his brothers age."

since b represents the age of his brother, one half his brothers age is 1/2b  

That leaves us with 1/2b - 5

The equation illustrates that the temperature by 11:30 am will be 2 degree Celcius.

It should be noted that there are 3 hours and 30 minutes from 8 am to 11.30 am.

Therefore, the temperature by 11:30 will be:

= -5 + 2(3.5)

= -5 + 7

= 2°

In conclusion, the correct option is 2°.
