Answer:
Irrational
Step-by-step explanation:
Any non-zero rational number multiplied by an irrational number will be irrational. We can rewrite this as (8.57... * 5) / 8, but we have no idea how to make 8.57... * 5 rational, or expressed as the quotient of two integers.
Answer:
cost of tacos=$2
cost of soda=$1
Step-by-step explanation:
x=price of tacos
y=price of soda
3x+y=7 --> y=7-3x
4x+2y=10 --> y=5-2x
5-2x=7-3x
x=2
y=5-2(2)=1
To find the mean of a dot plot, add up all of the data and divide by how many numbers there are.
In this case, the data added up is 4 + (5 x 4) + (6 x 3) + (7 x 2) + 10
4 + (5 x 4) + (6 x 3) + (7 x 2) + 10 = 66
With this information, we can now find the mean.
66/11=6
Therefore, the mean is 6. Hope this helps! Feel free to ask any questions.
Answer & Step-by-step explanation:
Devin runs an average of 15 min in 7 days
15 * 7 = 105 minutes
She has a goal of running 10² min. in 7 days
10² = 100 minutes
Will she complete her running goal in 7 days?
Yes. On average, she will run 105 minutes in seven days which is more than her 100 minute goal.
Answer:
Sin (E) = √74/(2√23)
Step-by-step explanation:
Reference Angle = E
Hypotenuse = 2√23
Adjacent = 3√2
Opposite = DC = √(2√23)² - (3√2)²) = √(4*23 - 9*2) = √(92 - 18) = √74 (pythagorean theorem)
Recall SOHCAHTOA.
Thus,
Sin (E) = opp/hyp
Sin (E) = √74/(2√23)
