Answer:
328.5 cubic cm
Step-by-step explanation:
V= L x W x H
V = 7.3 x 10 x 4.5
Remember the pythagorean theorem.
a^2 + b^2 = c^2
The complex number is a+bi, the absolute value is 'c'
Answer: A.4/52
B.1/52
C.4/42
D.12/52
Step-by-step explanation:
A. Because there is 52 cards in a deck the answer will be out of 52. Since there is 4 aces in the whole deck the probability of player one getting all four aces is a 4/52.
B. Since there is 52 cards in a deck and only one ace of hearts it will be a probability of 1/52.
C. Since there are 52 cards in a deck the probability that they will hold an ace card is a 4/52 Bc there are four aces.
D. Because there are 52 cards in a deck, and 12 hearts in the deck in all they will have a chance of 12/52
You might need to simplify these fractions or convert to a percentage based on what your instructor wants.
Answer:
9/20 yes, 4/15 not. See below
Step-by-step explanation:
Pick 9/20 and multiply numerator and denominator by 5:
9/20 = 45/100
We know that if we divide a number by 100 we need to move the coma as two places left, so:
9/20 = 45/100 = 0.45
And this is a terminal decimal as we know where it ends.
On the other hand if we pick 4/15 let try to divide it (here I will do it 'manually'):
4 |_ 15
we can divide 4 by 15, so we use 40 and begin with a comma
40 |_ 15
0.
15 enters 2 times in 40 with a rest of 10, so:
40 |_ 15
30 0.2
100
100 divided by 15 is 6 and we have 10 as rest again, and again and again...
40 |_ 15
30 0.266.....
100
100
....
So, we will have 0.266666666666666 infinitely. The decimal for 4/15 is non terminating and is 0.26666666666666666...
