1) π
2)5/4
3) √7
4) √3/2
Answer:
2) 5/4
Step-by-step explanation:
The other numbers arent irrationals because they have infinite decimals, and that cant be expresed in a fraction (sorry if i said something wrong im learning english)
Answer:
2
Step-by-step explanation:
We are given that a decimal number d
d=0.12345678...
Where d is formed by writing in succession all the positive integers in increasing order after decimal point.
We have to find the 100th digit of d to the right of the decimal point.
Place of first digit 1 after decimal=Tenth
Place of second digit 2 after decimal=Hundredth
Place of third digit 3 after decimal=Thousandth
Therefore, 100th digit of d to the right of the decimal point=2
28.6%
65.0%
75.0%
Answer: The probability that the second tile that Maggie turns over has a plant on it, is 75.0 %.
Step-by-step explanation:
We have,
Number of tiles with pictures of plants = 7
And, number of tiles with pictures of animals = 2,
⇒ Total numbers of tiles = 7 + 2 = 9,
After removing one picture of plant tile,
The remaining number of plant tiles = 7 - 1 = 6,
And, total numbers of remaining tiles = 9 - 1 = 8.
Since,
(Because, 0.01 = 1% ⇒ 0.75 = 75% )
Thus, the probability that the second tile that Maggie turns over has a plant on it, is 75.0 %.
Answer:
Volume of the portion = 1.6 cubic inches
Step-by-step explanation:
Since, wooden dowel is in the shape of a cylinder,
Formula to be used to find the volume of the part Anna has cut from the dowel will be,
Volume = πr²h
Where r = radius of the cylinder or part of the wooden dowel
h = length of the portion
By substituting the values in the formula,
Volume = π(0.5)²(2)
= 0.5π
= 1.57 in³ ≈ 1.6 cubic inch
Therefore, volume of the portion will be 1.6 in³.
