What is 60 over 40 in a mixed fraction

jeyben [28]

Answer:

1 1/2

Step-by-step explanation:

60/40 = (60 ÷ 20)/(40 ÷ 20) = 3/2; 3 > 2 => improper fraction Rewrite: 3 ÷ 2 = 1 and remainder = 1 => 3/2 = (1 × 2 + 1)/2 = 1 + 1/2 = = 1 1/2, mixed number (mixed fraction)

Maria has eight black marbles, fourteen clear marbles, and twelve blue marbles in a bag. If she picks two marbles at random, wit

horrorfan [7]

Answer:

$\boxed{0.15}$

Step-by-step explanation:

Part 1: Solve for the total amount of marbles

To solve for the probability of certain events, a population is needed to derive this information from. In order to find this population, add up the amounts of each marble.

8 + 14 + 12 = 34 marbles

Part 2: Determine the probabilities

Now, given the amounts of marbles, simply multiply the ratios of blue marbles to total marbles and the ratio of clear marbles to total marbles to get the combined probability.

$\frac{12}{34}*\frac{14}{33} = \frac{28}{187} \approxeq 0.1497 \approxeq 0.15 * 100 = 15$

The probability of these events occurring simultaneously is 15%.

Replace ∗ with a monomial so that the trinomial may be represented by a square of a binomial: 25a^2+ ∗ + 1/4b^2

Nadya [2.5K]

The square of a binomial is a pattern you would do well to remember.
.. (x +y)^2 = x^2 +2xy +y^2

Your expression has x^2 = 25a^2, so x = 5a. It also has y^2 = (b^2)/4, so y = b/2.
then the middle term is
.. 2xy = 2(5a)(b/2) = 5ab

The trinomial is
.. 25a^2 +5ab +(1/4)b^2 = (5a +b/2)^2
