Complete Question:
Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. Which quantity depends on the other?
A. The distance traveled depends on the number of hours traveled.
B. The number of hours traveled depends on the speed of the train.
C. The speed of the train depends on the distance traveled.
D. The speed of the train depends on the number of hours traveled.
Answer:
A. The distance traveled depends on the number of hours traveled.
Step-by-step explanation:
Recall:
Distance traveled = speed * time
The distance between or route taken from one point to the other is usually fixed
Here, the speed of the train , rate is constant, hence for the journey, speed is constant ;
Speed = K
Distance = K * time
Hence, the distance traveled in this scenario depends on the time of travel.

Step-by-step explanation:
The spinner shown has eight congruent sections. The spinner is spun 120 times. What is a reasonable prediction for the number of times the spinner will land on an even number?
Before I begin, let's go over probability.
The probability of an event is: (the number of ways something can happen) / (total number of outcomes possible). So, for example, the probability of rolling a one on a die can be found like:
There is 1 way to roll a one, and 6 possible sides, so the probability is 1/6.
And, if we were to roll the die 60 times, we could expect about 1/6 of the times to be a one, so we should expect a one to be rolled 1/6 * 60 = 10 times.
Now, onto the problem.
Each portion is congruent (they all have the same area). Thus, there is a 1/8 chance of landing on 1, a 1/8 chance of landing on 9, etc.
5 sections are odd, while 3 sections are even. So, the chance of landing on an even number is:
(3 ways to land on an even number) / (8 possible outcomes) = 3/8
If there is a 3/8 possibility to land on even, and there are 120 outcomes, we can say that an even number statistically should be rolled 3/8 * 120 times.
3/8 * 120 = 45
Thus, the answer is b, 45 times
Just in case, let's check the answer by finding the number of times we should roll an odd number and adding it to the number of even times and if it adds up to 120, then the answer is correct.
Because there is a 5/8 chance of getting an odd number, there should be about 5/8 * 120 = 75 times that an odd number is spun.
75 + 45 = 120, so the answer is correct.
I hope this helps! Feel free to ask any questions!
Mary has $6,000 saved for her college education. She invested that money at 2.3% interest per year. Suppose her account earned interest compounded annually. How much interest would she earn in 3 years?
Answer:
Interest= $423.59
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $6,000
Number of periods (n)= 3 years
Interest rate (i)= 2.3% = 0.023
To calculate the Future Value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 6,000*(1.023^3)
FV= $6,423.59
Now, the interest earned:
Interest= 6,423.59 - 6,000
Interest= $423.59

What is the domain of the function represented by the graph?
Answer: C. x>= -5
Step-by-step explanation:
Domain is all possible x-values
As you can see from the graph, the x-values do not go to the left of -5
so the domain is:
x >= -5

why is 1/5 fraction bigger then 1/2 fraction
Answer:
Because when you cut a pizza into one half, and another pizza into 5ths, the slice of the 1/2 pizza is bigger than the 1/5th pizza. I would suggest using a number line for this.

The difference of twice a number and 6 is at most −30.
Answer:
-12
Step-by-step explanation:
2n - 6 = -30
Add both 6 on each side
2n - 6 + 6 = -30 + 6
2n = -24
Divide 2 on both sides
[tex]\frac{2n}{2} = \frac{-24}{2}[/tex]
n = -12

Answer:
x = 3 and y = 1
Step-by-step explanation:
x + y = 4
2x - y = 5
We know x must be greater than y.
Let's try x = 3 and y = 1
3 + 1 = 4

it a deli Charges $2.24 for &
8ounces ham how much will
it Charge for 6ounces?
Answer:
$1.68
Step-by-step explanation:
[tex]\frac{8}{2.24}=\frac{6}{x} \\8x= 6(2.24)\\8x= 13.44\\x= 1.68[/tex]
Answer:
$1.68
Step-by-step explanation:
Since 8 ounces of deli charges $2.24, 1 ounce costs $0.28 because 2.24 divided by 8 is 0.28. Then, you multiply 0.28 by 6 since you are trying to find how much 6 ounces of deli costs. 0.28 times 6 is equal to 1.68. So, 6 ounces of deli costs $1.68.

what is the measure of x if angle 6 equals 4x and angle 7 equals 2x + 34
112°
64°
17°
68°
Answer:
17°
Step-by-step explanation:
6 = 4x
7 = 2x + 34
4x - 2x = 2x
Since 6 and 7 are vertically opposite angles, they have the same angle.
2x = 34
X = 34 ÷ 2 = 17
Step-by-step explanation:
< 6 and < 7 are vertically opposite angles so.
< 6 = < 7
4x = 2x + 34°
4x - 2x = 34°
2x = 34°
x = 17°
