Answer:

25.1mm²

Step-by-step explanation:

Total surface area of a cylinder = 2πr(r+h)

r is the radius = 1.2mm

h is the height = 2mm

Substitute

TSA = 2(3.14)(1.2)[1.2+2]

TSA = 7.536[3.2]

TSA = 24.1152

Hence the total surface area of the cylinder is 25.1mm²

Answer: less than.

Explanation:

1) The function f(x)= [x] returns the integer number that is less than x.

2) For example,

[3.0] = 3

[3.01] = 3

[3.25] = 3

[3.55] = 3

[3.99] = 3

[4.00] = 4

What is the complete factorization of x² + 4x-45? OA (X+15X(x - 3) OB. (x-9)(x+5) OC. (x+9XX-5) OD. (x-15)(x+3)​
alexira [117]

Answer:

(x+9)(x-5)

x * x = x^2

9 * x = 9x

5 * x = 5x

9x + 5x = 14x

-5 x 9 = -45

x^2 + 9x + 5x -45

x^2 + 14x - 45

MilA has a bag filled with marbles in which situations would the probability of mila drawing a blue marbles from the bag be 1-3
Kamila [148]
Since there were no situation given, I can only provide you with some guidance so you can select the correct answer.

If the probability is 1/3, that means that one out of every three options will need to be blue. 

If it is a bag of marbles, you could have 1 blue marble out of a total of 3 marbles. Or any other fraction that reduces to one third.

Here are some examples:

2/6   3/9   4/12   5/15   6/18   7/21   8/24 .....
