Unless you just want to give money to the ice cream truck, for 0 items, you will pay 0.
Since the price of each item is $0.77, for one item you will pay $0.77. (Is that a surprise?)
Then for two items, you will pay $0.77 for each one, or $0.77 + 0.77 = $1.54. You can also compute this by making use of the fact that multiplication is a shortcut for repeated addition. The price can be found by $0.77×2 = $1.54 = f(2).
Similarly, for 3 items, you can add $0.77 three times: $0.77 + 0.77 + 0.77 = f(3), or you can use multiplication: $0.77×3 = $2.31 = f(3).
a) Our table looks like
(x, f(x))
(0, 0)
(1, 0.77)
(2, 1.54)
(3, 2.31)
b) By now, I'm sure you have realized that to find the price of x items, you multiply 0.77 by x.
f(x) = 0.77x
Answer:
20 m
Step-by-step explanation:
the distance from the top car to the bottom car is equal to the diameter of the wheel. The diameter is 40 m, and that is twice the radius. The radius of the Ferris wheel is (40 m)/2 = 20 m.
Answer:
the aswer is 2
Step-by-step explanation:
this is because 10/5=2
A table of values can be used to represent variables that are directly proportional.
The complete table of proportions is:
![\left[\begin{array}{ccccccccc}Letters&10&2&[150 ]&7&1&500&[420] \\Cost&0.45&0.90&6.75&[0.315]&[0.045 ]&[22.5 ] & 18.90\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccccccccc%7DLetters%2610%262%26%5B150%20%5D%267%261%26500%26%5B420%5D%20%5C%5CCost%260.45%260.90%266.75%26%5B0.315%5D%26%5B0.045%20%5D%26%5B22.5%20%5D%20%26%2018.90%5Cend%7Barray%7D%5Cright%5D)
Given that
![\left[\begin{array}{ccccccccc}Letters&10&2&[\ ]&7&1&500&[\ ] \\Cost&0.45&0.90&6.75&[\ ]&[\ ]&[\ ] & 18.90\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccccccccc%7DLetters%2610%262%26%5B%5C%20%5D%267%261%26500%26%5B%5C%20%5D%20%5C%5CCost%260.45%260.90%266.75%26%5B%5C%20%5D%26%5B%5C%20%5D%26%5B%5C%20%5D%20%26%2018.90%5Cend%7Barray%7D%5Cright%5D)
Let:
<em />
<em> Letters</em>
<em />
<em> Cost</em>
<em />
Using proportional reasoning, we have:
Where
<em />
<em> ratio of proportion</em>
For the first values of C and L, we have:
Divide both sides by 10
So, the equation of proportion is:
<u>When C = 6.75, we have:</u>
Solve for L
<u>When L = 7, we have:</u>
<u>When L = 1, we have:</u>
<u>When L = 500, we have:</u>
<u>When C = 18.90, we have:</u>
Solve for L
Hence, the complete table is:
