12^3 / 12^7 = 12^3-7
= 12^-4
Answer:
70 m/s
Step-by-step explanation:
speed = √( g x depth ); where g = 9.8m/s²
given depth = 500m
equation becomes:
speed = √( g x depth )
= √( 9.8 x 500 )
= √( 9.8 x 500 )
=√4900
=70 m/s
Answer: The probability of pulling a Queen has a smaller chance of happening.
Step-by-step explanation: In a 52-card deck, you have 4 Queens altogether belonging to each of the four suits. If you pull a card at random out of a complete pack, the probability of picking a Queen would be as follows;
P(Q) = Number of required outcomes/Number of all possible outcomes
P(Q) = 4/52
P(Q) = 1/13
P(Q) = 0.07692 or 7.69%
Also in a 12-pair pack of socks, you have 3 pairs with the color grey. The probability of picking a pair of grey socks at random is given as follows;
P(G) = Number of required outcomes/Number of all possible outcomes
P(G) = 3/12
P(G) = 1/4
P(G) = 0.25 or 25%
Therefore the probability of pulling a Queen has a 7.69% chance of happening and thats a lower chance.
Answer:
2x - 8
Parts of an equation:
2 - coefficient
x - variable
8 - constant
The number 2 is not a coefficient in the expression. FALSE.
The expression has three terms. FALSE. two terms only: 2x & 8
The variable in the expression is x. TRUE
The number 2 is a constant in the expression. FALSE
The expression has one variable term. FALSE. 2x is term but it's a combination of a number and a letter. Variable term is letter only.
Answer:
1x + 4y = 4 ⇒ 6x + 24y = 24
6x - 8y = 0 ⇒ 6x - 8y = 0
32y = 24
32 32
y = 3/4
x + 4(3/4) = 4
x + 3 = 4
-3 -3
x = 1
(x, y) = (1, 3/4)
