What is the answer to this question please explain (picture included)

Answers

easy peasy
just use PEMDAS and some exonential laws

(x^(m))(x^(n))=x^(m+n)
(x^(m))^(n)=x^(mn)
(ab)^(m)=(a^(m))(b^(m))

also another is x^{(m)/(n)}=\sqrt[n]{x^(m)}

so

[3(2a)^{(3)/(2)}]^(2)=
(3^(2))((2a)^{(3)/(2)}^(2))=
(9)((2a)^{(3)/(2)}^(2))=
(9)((2a)^{(6)/(2))=
(9)((2a)^(3)) =
(9)(8a^(3)) =
72a^(3)

What are three ways a rectangle and a square are alike

Answers


-- Each has 4 sides.
-- Opposite sides of each are parallel.
-- Opposite sides of each have equal length.
-- Interior angles of each sum to 360 degrees.
-- Each is a special case of parallelogram.
-- Each has all interior angles equal.
-- Area of either one is (length) x (width).
Rectangles and squares are alike in that both have two pairs of parallel sides and four right angles. They are different because a square must have four equal sides lengths and a rectangle has two pairs of equal side lengths.

Tim has 51 tiles mixed together in one bag.13 are green, 23 are white and 15 are yellow.
Tim picks tiles randomly from the bag one at a time and fixes them to the wall.
The first tile he chooses is green.
What is the probability that the second tile he chooses will be yellow?
Express your answer as a percentage.

Answers

Answer:

30% will be yellow

Step-by-step explanation:

13 green

23 white

15 yellow

51 in all

1 green tile is chosen

50 tiles left in all

Probability of yellow.

15 out of 50 = 15/50 = 3/10 = 0.3

To percentage.

0.3 × 100 = 30

30 add %

30%

Answer:

30%.

Step-by-step explanation:

After picking the green one there are 50 tiles left in the bag.

Probability the second is yellow = number of yellow tiles / 50

= 15/50

= 3/10

= 30%.
