Find the product of 543 and 36.
A. 507
B. 19,548
C. 15.08
D. 579

Answers

Answer 1

Answer: 1 Set up the long multiplication.

543x36

2 Calculate 3 x 6, which is 18.
Since 18 is two-digit, we carry the first digit 1 to the next column.

3 Calculate 4 x 6, which is 24. Now add the carry digit of 1, which is 25.
Since 25 is two-digit, we carry the first digit 2 to the next column.

4 Calculate 5 x 6, which is 30. Now add the carry digit of 2, which is 32.
Since 32 is two-digit, we carry the first digit 3 to the next column.

5 Bring down the carry digit of 3.

6 Calculate 3 x 3, which is 9.

7 Calculate 4 x 3, which is 12.
Since 12 is two-digit, we carry the first digit 1 to the next column.

8 Calculate 5 x 3, which is 15. Now add the carry digit of 1, which is 16.
Since 16 is two-digit, we carry the first digit 1 to the next column.

9 Bring down the carry digit of 1.

10 Calculate 3258 + 16290, which is 19548

11 Therefore, 543 x 36 = 19548.

The answer is B.19548

Answer 2

Answer: B. 19,548 because a product is an aswer in amultipacation problem so you would have to multiply 543 x 36

What is square root of 80 in simplified radical form?A.8 square root over 10

B.10 square root over 8

C.5 square root over 4

D.4 square root over 5

Answers

The number √80 in simplified radical form is 4√5. Therefore, the correct answer is option D.

The given number is √80.

Radical form is the expression that involves radical signs such as square root, cube root, etc instead of using exponents to describe the same entity.

Here, factors of number 80 are 2×2×2×2×5

= √16×5

= 4√5

Therefore, the correct answer is option D.

A certain type of bacteria doubles every 8 hours. A culture begins with 30 000. Without use of given equation, use the help of your ability to set up a pattern to determine how many bacteria are there after a) 8 hours b) 16 hours c)d days

Answers

Not sure what you mean by "without use of given equation".
At time 0hrs, there is 30 000.
Since it doubles every 8hrs, at time 8hrs there is 60 000 or 30 000 x 2
In another 8hrs, it will double again, so at time 16hrs, it will be 120 000 or 30 000 x 2 x 2
In another 8hrs, double again, so at time 24hrs, it will be 240 000 or 30 000 x 2 x 2 x 2
This is also 30 000 x 8 as 2x2x2=8. I'll come back to this later.

You add an extra x 2 for each 8 hrs. By the end of the 2nd day, it would be
30 000 x2 x2 x2 x2 x2 x2
This is also
30 000 x8 x8
Every day we add an extra x8
We use powers to specify this.
30 000 x 8^d
So after 4 days
30 000 x 8^4 = 30 000 x8 x8 x8 x8
Note that this is NOT the same as 30 000 x 8 x 4

What is the volume, in cubic cm, of a cylinder with the height of 16cm and a base radius of 3 cm, to the nearest tenths place?

Answers

452.16 cm³ is the volume of a cylinder with the height of 16cm and a base radius of 3 cm

Volume of cylinder based problem:

Height of cylinder = 16 cm

Radius of cylinder = 3 cm

Volume of cylinder = πr²h

Volume of cylinder = (3.14)(3)²(16)

Volume of cylinder = (3.14)(9)(16)

Volume of cylinder = 452.16 cm³
