Answer:
780 cubic inches
Step-by-step explanation:
Step one:
Given data
The bottom surface of the box has an area of 65 square inches.
Already given an area and a height of 12 in
we proceed to find the volume by multiplying Area and height
Required
The volume of the box
Volume= Area* height
Step two:
Volume= 65*12
Volume = 780 cubic inches
Hi there!
Using compatible numbers it would be:
12 ÷ 2 = 6.
Now when you divide it, the answer would be close to 6.
So, 12 ÷ 2 = 6 would be using compatible numbers.
Hope this helps ;)
Answer:
I cannot understand this question
Step-by-step explanation:
I don't know what is in the question
Let α represent the acute angle between the horizontal and the straight line from the plane to the station. If the 4-mile measure is the straight-line distance from the plane to the station, then
sin(α) = 3/4
and
cos(α) = √(1 - (3/4)²) = (√7)/4
The distance from the station to the plane is increasing at a rate that is the plane's speed multiplied by the cosine of the angle α. Hence the plane–station distance is increasing at the rate of
(440 mph)×(√7)/4 ≈ 291 mph
The profit is originally 250% to maintain this you need to multiply the new unit cost by 2.5.
New unit cost $1.25. * 2.5 = $3.12.5
