45 miles / 1 hour = 45 miles / 60 minutes
Set up a ratio:
45mi/60m = x mi/1m
x = (45×1)÷60 = 0.083333.... mi
Approximately 0.083 miles per minute
Answer:
37
Step-by-step explanation:
Add all the numbers up and you will get 370. How many numbers are there in total? 10 right so you divide 370 with 10 and get 37.
hope this help
Given the expression:
-x^2+18x-99
to solve by completing squares we proceed as follows:
-x^2+18x-99=0
this can be written as:
-x^2+18x=99
x^2-18x=-99.......i
but
c=(-b/2)²
Hence:
c=(-(-18)/2)²=81
adding 81 in both sides of i we get:
x^2-18x+81=-99+81
factorizing the quadratic we obtain:
(x-9)(x-9)=-18
thus
(x-9)²+18=0
the above takes the vertex form of :
y=(x-k)²+h
where (k,x) is the vertex:
the vertex of our expression is:
(9,18)
hence the maximum point is at (9,18)
NOTE: The vertex gives the maximum point because, from the expression we see that the coefficient of the term that has the highest degree is a negative, and since our polynomial is a quadratic expression then our graph will face down, and this will make the vertex the maximum point.
Convert 16 tenths into .16 so
5 - .16 = 4.84
divide the price of the olive oil by the volume of the olive oil
to find the price per ounce. 5.88/25oz=0.2352 dollars/ounce. Then you
have to multiply the volume of the bottle by .60 to find what 60% of the
volume is.
0.60x25=15 ounces. since in the first two weeks she used 15
ounces which has a price of 0.2352 dollars/ounce you have to multiply
15 by 0.2352 which equals 3.528 dollars.
