Answer:
Volume = 499 ft
Step-by-step explanation:
Calculate the volume of the room.
<span>Time = Distance/Speed
Time = 153/70
Time = 2.19 hours.
Time = 2 hours 11 minutes.

Answer:
(a) 20256.15625
(b) 17642.78546
Step-by-step explanation:
(a) There's a formula for this problem y = A(d)^t where, A is the initial value you are given, d is the growth or decay rate and t is the time period. So, in this case, as the car cost is decreasing it is a decay problem and we can write the formula as such; y = A(1-R)^t
So, in 5 years the car will be worth, 25500(1-4.5%)^5 or 20256.15625 dollars
(b) And after 8 years the car will be worth 25500(1-4.5%)^8 or 17642.78546 dollars.
The situation in the question can be represented by a right triangle with a hypotenuse of 45 feet and one of the angles as 50 degrees. We are to find the side opposite angle 50 degrees, hence we make use of sine of angles.
Let the height of the building be x, then
Therefore, the height of the building is 34.5 feet to the nearest tenth of a foot.
Answer:
m=-29/3 and n=65/3
Step-by-step explanation:
The given system has equations:
3m+3n=36
8m+5n=31
Multiply the top equation by 5 and bottom equation by 3 to get:
15m+15n=180
24m+15n=93
Subtract the top equation from the bottom equation to get:
9m=-87
Divide both sides by 9
We substitute this value into the first equation to get:
