Answer:
64 in²
Step-by-step explanation:
Hello There!
The figure shown is a cube
We can easily find the area of the base by squaring one of the side lengths
area of base = 8²
8²=64
so the area of the base is equal to 64 in²
Note: this only works with cubes as all side are equal to each other
1 minute = 60 seconds
1 hour = 60 minutes = 60*60 seconds = 3600 seconds
1 hour = 3600 seconds
Multiply both sides by 2.1 to get
1 hour = 3600 seconds
2.1*(1 hour) = 2.1*(3600 seconds)
2.1 hours = 7560 seconds
Now use the formula below
d = r*t
where,
d = distance
r = rate or speed
t = time
In this case,
d = unknown
r = 4 ft per sec
t = 7560 seconds (equivalent to 2.1 hours)
So,
d = r*t
d = 4*7560
d = 30240
The bird can travel 30240 feet. Convert this to miles by dividing the value by 5280 (since 1 mile = 5280 feet)
30240/5280 = 5.727 roughly which rounds to 5.7
Answer: C) 5.7 miles
Answer:
Dr. Gavin needs to recruit 200 participants.
Step-by-step explanation:
Dr. Gavin is conducting a 2 x 4 independent-groups factorial design.
This means that there will be 2*4 = 8 cells.
Assuming he wants 25 people in each cell, how many participants does Dr. Gavin need to recruit?
25 people in each cell, 8 cells. So
25*8 = 200
Dr. Gavin needs to recruit 200 participants.
Answer:
The change in the depth of water per minute
Step-by-step explanation:
We are given a graph that shows the depth of water in a bathtub as water drains out
Slope is the rate of change
We can see in the graph that on increasing the value x , the value of y decreases .
x axis represents the minutes
y axis represents the depth of water(inches)
So, On increasing minutes , the depth of water decreases
So, there is a change in depth of water per minute
So, Option D is correct
The change in the depth of water per minute
