Answer:
a. 8 minutes
b. 7.5 tasks
Step-by-step explanation:
of an hour is just 40 minutes.
Let's use a ratio:
minutes : tasks
40 : 5
8 : 1
20 : 2.5
60 : 7.5
a. 8 minutes
b. 7.5 tasks
Answer:
Dimensions 30 in x 30 in x 15 in
Surface Area = 2,700 in²
Step-by-step explanation:
Let 'r' be the length of the side of the square base, and 'h' be the height of the bin. The volume is given by:
The total surface area is given by:
Rewriting the surface area function as a function of 'r':
The value of 'r' for which the derivate of the surface area function is zero, is the length for which the area is minimized:
The value of 'h' is:
The dimensions that will ensure the minimum surface area are 30 in x 30 in x 15 in.
The surface area is:
Answer:
i think the answer is 43 degrees but i dont know
25% is equal to 100/25=1/4
We can substitute this into an equation to get the total number of wells where n can be equal to the total number of wells.
1/4*n=50
n/4=50
n=50*4
n=200
The total number of wells that were drilled was 200.
Answer:
After 22 seconds the projectile reach its maximum height of 4,840 units
Step-by-step explanation:
we have
This is a vertical parabola downward (because the leading coefficient is negative)
The vertex is a maximum
Find out the coordinates of the vertex
Convert the quadratic equation in vertex form
Factor -10
Complete the square
Rewrite as perfect squares
The vertex is the point (22,4,840)
therefore
After 22 seconds the projectile reach its maximum height of 4,840 units
