Answer: $26
Step-by-step explanation:
If $19.50 is 3/4, we need to find 4/4.
3/4 -> 0.75
4/4 -> 1
We will set up a proportion and solve.
19.5 = 0.75x
26 = x
The professional ball is $26.
Answer:
-6
Step-by-step explanation:
Answer:
The function is y = 40 * 2^(x/2)
The graph is in the image attached
Step-by-step explanation:
The function that models this growth is an exponencial function, that can be described with the following equation:
y = a * b^(x/n)
Where a is the inicial value, b is the rate of growth, x is the time and n is the relation between the time and the rate (the rate occurs for every two hours, so n = 2).
Then, using a = 40, r = 2 and n = 2, we have:
y = 40 * 2^(x/2)
If we plot this function, we have the graph shown in the image attached,
It is an exponencial graph, where the value of y increases very fast in relation to the increase of x.
Answer:
of the lasagna is left
<u>Step-by-step explanation:</u>
Given:
Amount of lasagna Rico eats = 1/9
Amount of lasagna His friend eats = 1/18
To Find:
The amount lasagna is left =?
Solution:
Total lasagna ate by both Rico and his friend = Amount of lasagna Rico eats + Amount of lasagna His friend eats
Total lasagna ate by both Rico and his friend =
Total lasagna ate by both Rico and his friend =
Total lasagna ate by both Rico and his friend =
Total lasagna ate by both Rico and his friend =
The amount lasagna is left = 1 - Total lasagna ate by both Rico and his friend.
The amount lasagna is left =
The amount lasagna is left =
The amount lasagna is left =
