Answer:
240 feet per hour
Step-by-step explanation:
Given that:
Submarine is descending for examining the sea floor.
Distance of sea floor from the surface = 2100 feet
Time taken for the descend = 8.75 hours
To find:
The rate of descent in feet per hour = ?
Solution:
Here, we are given the distance traveled in feet and the time taken to travel that distance in hours.
And we have to find nothing but the speed of the submarine.
First of all, let us have a look at the relationship among speed, distance and time.
Putting the values of distance and time.
Answer:
Is
Step-by-step explanation:
Correct answer is A I think
9(4+6) because you can use distributive property to get the answer
Let x = quantity of bicycles
($160x) - ($80x) = $2800. To solve for x, we have to combine the terms on the left side.
$80x = $2800. Divide each side by $80.
x = 35.
35 bicycles must he sold each month to break even.
Answer:
(x−5y)(9x+8)
Step-by-step explanation:
9x^2−45yx+8x−40y
Do the grouping 9x^2−45yx+8x−40y=(9x^2−45yx)+(8x−40y), and factor out 9x in the first and 8 in the second group.
9x(x−5y)+8(x−5y)
Factor out common term x−5y by using distributive property.
(x−5y)(9x+8)
