Answer:

5.4*10^{5}-1.2*10^{3}=5.388*10^{5}

Step-by-step explanation:

We can rewrite 1.2*10^{3} as 0.012*10^{5}.

Now, let's subtract each term:

5.4*10^{5}-0.012*10^{5}

we can take a common factor.

(5.4-0.012)*10^{5}=5.388*10^{5}

Therefore the answer is  5.388*10^{5}.

I hope it helps you!

What's the lateral area of a right cylinder if the radius of the base is 12mm and the altitude of the cylinder is 5 times the ba
gizmo_the_mogwai [7]

Answer:

1440π squared mm.


Step-by-step explanation:

Given is the radius of base of cylinder, r = 12mm.

The altitude is five times the base radius, h = 5 times 12mm = 60mm.

The lateral area of the cylinder is the curved surface area of the cylinder.

The formula for curved surface area of cylinder is as follows:-

Curved Surface Area = Circumference of base x altitude of cylinder.

SA = 2πrh = 2π•12•60 = 1440π sq. mm.

Hence, Lateral area of cylinder is 1440π squared mm.

Find a set of 5 positive integers that has a possible mode of 5, a median of 7 and a mean of 9​
Pavel [41]

Answer:

You could have a set of [5, 7, 13, 15, 5]

Step-by-step explanation:

The mode is 5 (5 occurs the most in the set).

<u>Definition of the mode of a set:</u>

The mode of a set of data is the value in the set that occurs most often. In the problem above, 18 is the mode. It is easy to remember the definition of a mode since it has the word most in it. Fun fact: The words mode and most both start with the letters mo.

The median is 7 (if you put the numbers in strictly increasing order, 7 will be the middle number).

<u>Definition of the median of a set:</u>

The median of a set of data is the middlemost number or center value in the set. The median is also the number that is halfway into the set. To find the median, the data should be arranged, first, in order of least to greatest or greatest to the least value.

The mean is 9 (5 + 7 + 13 + 15 + 5).

<u>Definition of the mean of a set:</u>

The mean is the mathematical average of a set of two or more numbers. The arithmetic mean and the geometric mean are two types of mean that can be calculated. Summing the numbers in a set and dividing by the total number gives you the arithmetic mean.

Hope this helps.
