Answer:
2.3 feet/ second
Step-by-step explanation:
To find the rate of change, we will have to find the difference in his distance travelled and divide it by the time taken to move that distance.
This is given by rate of change = (change in position)/ change in time
From the question, his position changed from 30 ft to 100 ft thus the distance he travelled is = 100ft - 30 ft = 70 ft.
Time taken to travel this distance = 40 seconds - 10 seconds = 30 seconds
Diver's rate of travel = 70 ft / 30 seconds = 2.33333ft/second.
Rounding off the answer to the nearest tenth, we have 2.3 ft/second
9514 1404 393
Answer:
D. in quadrant III
Step-by-step explanation:
The signs of the coordinates tell you the point is located left of, and below, the origin (where the axes cross). That puts it in Quadrant III.

Answer:
468.75 square inches
Step-by-step explanation:
Let the length of Julian's tank be x
Let the width of Julian's tank be y
So, Area of Julian's tank=
Since we are given that Julian's tank is approximately 300 square inches
So,
--1
Now we are given that The dimensions of his friend's tank are each exactly
times the dimensions of Julian's tank.
So,length of his friend's tank =
So,width of his friend's tank =
So, Area of his friend's tank=
=
=
(Using 1)
=
Hence the approximate area of the rectangular base of his friend's tank is 468.75 square inches.
So, Option D is correct.
