Answer:
Her brother gave his friends one half the pie.
Step-by-step explanation:
The whole pie is equal to 6/6, because that's equal to one. 1/3 = 1/6. 6/6 - 2/6 = 5/6. 5/6 - 2/6 = 3/6. 3/6 = 1/2.
Answer:
All real solutions
Step-by-step explanation:
- The given graph is a maximum quadratic function.
- The solution to the graph is where the graph intersects the x-axis.
- We can see from the graph that, the function intersected the x-axis at two different points, hence its discriminant is greater than zero.
- Hence the solution of g(x) are two distinct real solutions.
- The solutions are not whole numbers because the x-intercepts are not exact.
- The solutions are also not all points that lie on g(x)
- The first choice is correct.
Answer:
Answer C is the only one in function notation.
Step-by-step explanation:
To find something in function notation, we look for 2 different criteria.
- On the left side, it must say f( ), with a variable in the parenthesis.
- On the right side, the variable being used must match that from the left side.
Since C is the only one that satisfies both of those needs, we know it is the answer.
Let p = number of pennies.
Let n = number of nickels.
We are given that n= 2p and the total value is $8.80.
We know that a penny = $0.01 and that a nickel = $0.05.
So $0.01p + $0.05n = $8.80.
Substitute 2p for n:
$0.01p + $0.05*2p = $8.80
$0.01p + $0.10p = $8.80
$0.11p = $8.80
p = 80
So n = 2p = 2*80 = 160
Thus there are 80 pennies ($0.8) and 160 nickels ($8.00). The value of all the coins is $8.80.
