The total amount of change, in cents, that was found is determined as 96 cents.

<h3>Total amount of change</h3>

The total amount of change is calculated as follows;

let the total = T

there was at least one coin of each type

T = p + n + d + q

more than half of the coins were pennies

\frac{p+n + d + q }{2} \leq  p

<h3>Value of the coins</h3>
  • pennies = $0.01
  • nickels = $0.05
  • dimes = $0.1
  • quarters = $0.25

more than half = pennies

next, we have; nickels + dimes + quarters

<h3>number of dimes</h3>

y(dimes) = $0.25

y(0.1) = 0.25

y = 0.25/0.1

y = 2.5 ≅ 3

dimes = 3 coins

<h3>number of nickels</h3>

since dimes = 3 coins, number of nickels is now calculated as;

x(0.05) = 3(0.1)

x = (0.3)/(0.05)

x = 6 coins

nickels = 6 coins

<h3>Total coins</h3>

Total coins = nickels + dimes + quarters + pennies

  • pennies must greater than 6 coins, since we can't have fewer coins.

Total coins = nickels + dimes + quarters + pennies

let pennies = 7

Total coins = 6 + 3 + 1 + 7

Total coins = 17

half of 17 = 8.5

7 is less than half (8.5), number of pennies cannot be 7, since more than half of the coins are pennies.

let pennies = 11

Total coins = 6 + 3 + 1 + 11

Total coins = 21

half = 10.5

  • 11 is more than half (10.5)

more than half = number of pennies = 11

<h3>Total amount in cents</h3>

11($0.01) + 6($0.05) + 3($0.1) + 1($0.25) = $0.96 = 96 cents

Which is the graph of y =[x] -2?
just olya [345]

Answer:

In the graph of y = x2, the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point. We can graph a parabola with a different vertex.

jeremy paid 25.60 for 4 boxes of chocolates this can be expressed using the equation y=kx how much would it have cost jeremy if
Tcecarenko [31]
From the expression, the price is directly proportional to the boxes with k being the constant. therefore he bought 4 boxes for 25.6 having the initial constant to be 6.4
if he bought 10 boxes having a constant of 6.4 it becomes y=6.4*10 which becomes 64.

In the table, x and y are in a proportional relationship. у 3 -5.4 5 -9.0 9 -16.2 12 -21.6 Let x be the independent variable. Wh
aev [14]

Answer:

A. -1.8

Step-by-step explanation:

If x is the independent variable and y is the dependent variable, therefore constant of proportionality would be:

k = y/x

Using any pair of values from the table, we can find k. Let's use (3, -5.4):

k = y/x = -5.4/3

k = -1.8
