Answer:
The answer is B.
Step-by-step explanation:
We already know that there are 60 people in the orchestr, and we know 20 percent play cello. This mean that the second graph will help us figure out how many people play cello.
I hope this helps!! Please mark me Brainliest if it did!
I'm assuming each grid square= 1 square mile.
To do this, you first need to find the total distance.
The first component of his walk takes him from an x-coordinate of 2 to a coordinate of -4 1/2. Since the y-value remains the same, you're not worried about that for this part of the problem. The difference between 2 and -4 1/2 is 6 1/2, so that is your horizontal distance.
Now he walks from the (-4 1/2, -1 3/4) to (-4 1/2, 5 1/4). This time, the x-value is constant, so you only need to worry about the y. As they are on opposite sides of the x-axis, you can add the y-values to get a result of 7, which is your vertical distance.
I just realized I did those distances in reverse order, but it should be ok because the total distance is the same.
To find the total distance, add vertical to horizontal.
6 1/2 + 7 = 13 1/2. This is your total distance.
Now that you have both his speed (given), and total distance, you can find the time it will take him. If he is moving at 4 1/2 mph and the distance is 13 1/2 miles, you can use s=d/t to find the time. 3 1/2 miles divided by the time = 4 1/2 mph. To solve for t, multiply both sides by t and divide that by s, so t= d/s. we know d= 13 1/2 and s= 4 1/2, so t= 13.5 divided by 4.5 = 3. As his speed is in mph, the unit is in hours. Therefore, the answer should be 3 hours.
Answer: 15
Step-by-step explanation:
My answer is correct because, if in 22 weeks she learned 55 recipes of appetizers, the we have to divide 55 by 22. And 55 divided by 22 equals 2.5. So now since we have that and they are asking us what would it be for a total of 6 weeks then we just have to multiply 2.5 and 6. And 2.5 times 6 equals 15.
