Answer:
$6.22
Step-by-step explanation:
Given;
Total number of coins N = 50
Number of pennies p = 14% of N = 0.14 × 50 = 7
Number of dimes d = 32% of N = 0.32×50 = 16
Number of nickels n = 4 + number of pennies = 4+p
n = 4+7 = 11
Number of quarters q;
N = p+d+n+q
q = N - (p+d+n)
q = 50-(7+16+11)
q = 16
1 Penny = 1 cent = $0.01
1 Nickel = 5 cent = $0.05
1 dime = 10 cents = $0.10
1 quarter = 25 cents = $0.25
Total amount in the bag is;
C = 0.01p + 0.05n + 0.10d +0.25q
Substituting the values;
C = 0.01(7) + 0.05(11) + 0.10(16) + 0.25(16)
C = $6.22
The bag contains $6.22
Answer:
See below
Step-by-step explanation:
<u>Part A</u>
Remember that x-intercepts are located where y=0:
<u />
<u /><u />
<u /><u />
<u /><u />
<u /><u />
<u /><u />
<u /> and
<u>Part B</u>
Since the leading coefficient, -16, is negative, the parabola will open downward, making the vertex a maximum. We can determine the x-coordinate of the vertex using and plug it into the function to find the y-coordinate:
Now we find the y-coordinate given the x-coordinate:
Therefore, the coordinates of the vertex are .
<u>Part C:</u>
Notable points of a quadratic function include its x-intercepts, y-intercept, and vertex. Plotting these points on a graph help to visualize what the resulting graph of the function looks like. I've attached a graph with the function and the notable points for you to see.
Answer:
The answer is C.
Step-by-step explanation:
4 x 12 is how much money per worker per hour. 20 x 160 is how much the cost for the concrete. Adding them gets you the total cost.
