Answer:
5 tens and 8 ones gives 58
Step-by-step explanation:
We have to describe 58 as a sum of tens and ones
We know that first digit from the right is the ones place
Second digit is the tens place
Hence, 5 tens and 8 ones gives 58
Also, we can see that
10+10+10+10+10=50 (5 tens)
and 1+1+1+1+1+1+1+1=8 (8 ones)
on adding both we get 58
Hence, 5 tens and 8 ones gives 58
Step-by-step explanation:
First, we want to find profit given revenue and cost. Because profit = revenue - cost, we can write the profit function, P(x), as R(x) - C(x) and go from there.
P(x) = R(x) - C(x)
P(x) = (-x²+24x) - ( 10x + 30)
P(x) = -x²+24x - 10x-30
P(x) = -x²+14x-30
In a quadratic function such as this, the graph opens downward (meaning that it goes from up to down) if the leading coefficient is negative and vice versa. Here, since -1 is attached to x², we can say that the graph opens downward. The point where the direction of the slope changes (when it goes from up to down), or the peak of the quadratic, is called the vertex.
The x value of the vertex is given by -b/(2a) in a quadratic of form ax²+bx+c. As a=-1 and b=14 here, we can say that -b/(2a) =
-14/(2*-1) = -14/-2
= 7
Therefore, the x value of the vertex, or the number of containers sold that maximizes profit, is 7.
Answer:
30
Step-by-step explanation
We have 3 areas for parking and 2 aisles.
Each aisle is 10 ft wide , we have two we have 20 ft for aisles width then total width available for stalls
77 - 20 = 57
And each stall is 19 feet long then 57/19 = 3
And 80 ft long of the lot will permit 10 cars
Then we have each individuals set of stall with 10 parking places
Therefore
3 * 10 = 30
No, 1/2 is equivalent to 4/8
