Answer:
P = 500 - 40t
Step-by-step explanation:
P is the number of pages has left to read
the initial value is 500
the rate of change is 40 pages per hour (t)
you must subtract from the initial
The equation is P = initial - 40t or
P = 500 - 40t
To check, at 0 hours you have 500 pages or P = 500 - 40(0)
at 10 hours, P = 500 - 40(10) = 500 - 400 = 100
Answer:
arc length =11
Step-by-step explanation:
To find the arc length , we take pi *2 r and multiply by the fraction of the circle
The circumference is 12 which is equal to 2 * pi *r
arc length = 12 * 330/360
arc length = 12 * 11/12
arc length =11
Answer:
Step-by-step explanation:
The lengths can be found by considering their ratio:
short : long = 1 : 5
The sum of the ratio units is 1+5 = 6, and the sum of the lengths is 144 inches. That means each "ratio unit" stands for (144 in)/6 = 24 inches of length.
The lengths are ...
1 : 5 = 24 in : 120 in
The pieces are 24 inches and 120 inches in length.
__
Equivalently, you can let s represent the shorter length. Then 5s is the longer one, and their total is ...
s +5s = 144
s = 144/6 = 24
5s = 5(24) = 120
The lengths are 24 inches and 120 inches.

Answer:
3 = x
Step-by-step explanation:
Well, the two unknown sides share the same size due to the same angle, so now, using the fact we only have the info about one side, we need to do a reverse pythagorean theorem.
Our a and b are the same, so I will change them to "x" and combine them.
Now we plug in our "c" and square it ("C" in this case is: )
3 = x
