Answer:
2/7
Step-by-step explanation:
Each cat would get 1/20 of the whole bag of cat food.
This is the concept of applications of volume. We are required to calculate BTUs per cubic foot. This will be given by the formula:
(BTU)/volume
Total BTU=15*750=11,250
(assuming the bus is a perfect cuboid) volume of the bus will be;
volume=length*width*height
=38*8.5*6.25
=2018.75 ft^2
Thus the BTUs per foot will be:
11250/2018.75
5.57 BTUs/ft
Answer: Choice B
Building A; it is around 50.34 feet taller than building B
======================================================
Explanation:
Draw two right triangles such that they both have a reference angle of 40 degrees. Since it's an angle of elevation, place the angle near the horizontal side.
Opposite each reference angle is the height of the building, which we'll call h.
The adjacent side is the horizontal distance from the person to the building.
Building A is 120 ft away so it's height is...
tan(angle) = opposite/adjacent
tan(40) = h/120
h = 120*tan(40)
h = 100.69
This value is approximate. Make sure your calculator is in degree mode.
-----------------
Repeat the same idea for building B, except the adjacent side is smaller this time.
tan(angle) = opposite/adjacent
tan(40) = h/60
h = 60*tan(40)
h = 50.35
This value is approximate.
-----------------
Now subtract the heights
100.69 - 50.35 = 50.34
This shows that building A is roughly 50.34 taller than building B.
Answer:
The DC flight
Step-by-step explanation:
A fixed amount ($50) is always a larger fraction of a smaller number. It is a larger fraction of $200 than of $1250. The plane flight to Washington DC is affected relatively more by a variation of $50.
__
A price change of $50 on a base price of $200 is a percentage change of 25%. 50/200 × 100% = 25%
A price change of $50 on a base price of $1250 is a percentage change of about 4%. 50/1250 × 100% = 4%
