Answer:
140 minutes
Step-by-step explanation:
60/3 is 20.
20*7 is 140 minutes.
In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).
Since we are interested in pulling a black card first, the probability is 26/52.
Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).
Now that we want to pull a red card, we know that the probability will be 26/51.
Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)
The answer we are given is 0.2549
Answer:
Equivalent expression using n to represent the unknown number is: 
Step-by-step explanation:
The quotient of 56 and n is multiplied by 3.
Create an equivalent expression using n to represent the unknown number.
We need to write equivalent expression of The quotient of 56 and n is multiplied by 3.
We will do this step by step
First we will find:
The quotient of 56 and n
It can be written in mathematical form is: 
Now, we will find
The quotient of 56 and n is multiplied by 3.
It can be written in mathematical form as: 
So, equivalent expression using n to represent the unknown number is:
Answer:
(2, 5)
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
- 2x + y = 1 → (2)
Substitute y = x + 3 into (2)
- 2x + x + 3 = 1
- x + 3 = 1 ( subtract 3 from both sides )
- x = - 2 ( multiply both sides by - 1 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 2 + 3 = 5
Solution is (2, 5)
The "L"-shape would look like it fell backwards and was laying on the ground. The little leg of the L would be pointing up into the air.
A 90 degree counter clockwise turn means that it rotates left around the origin. It turns one half of half a turn, or 90 degrees.
