Answer:
24 piano lessons
Step-by-step explanation:
$0.18: One time
$4.32: ? times
You have to divide 4.32 by 0.18 which will give you 24. So Jennifer practiced 24 times. :)
I hope that helps! :D
P.S. I don't know how you're supposed to do it (i.e. proportions, ratios, etc.), so that's why I did it the way I learned. I just want to say: there are more ways to do this problem. :)

The length of AC is 9 meters
Step-by-step explanation:
The given scenario forms a right-angled triangle where Perpendicular = 6m (Picture Attached)
The trigonometric ratios can be used to find the required length.
When an angle is under consideration the side opposite to angle is perpendicular.
So,
Hence,
The length of AC is 9 meters

You can convert the description to symbolic representation.
The equation that can express how many cups of lemonade Jatonia sold is which results in
Whatever the condition is given, try converting it into symbolicforms.
For example, if it is said that something is increased, then you do addition by putting + sign.
You can use such techniques to convert given descriptions to equations or mathematical expressions mostly.
Since one cup is sold for 0.75 price, thus n cups will be sold in n times 0.75 price (since 0.75 + 0.75 ... n times is same as 0.75 times n)
This fact can thus, be written as
The cost for n cups is 18, thus the cost we get is equal to 18.
Thus, we have:
Since we need the expression for getting amount of cups(denoted by n), we will try to make n left alone in the left side.
Thus ,we will divide by 0.75 on both the sides.
Thus we get:
Thus, the equation that can express how many cups of lemonade Jatonia sold is which results in

The ratios are called equivalent ratios, which have the same values.
Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
Given to name the two ratios that have the same value,
The ratios are called equivalent fractions,
Comparable to equivalent fractions are equivalent ratios. An equivalent ratio results from multiplying or dividing the antecedent (the first term) and the consequent (the second term) of a given ratio by a non-zero value.
for example, 1/3 is also written as 2/6, 3/9, and so on,
and each of them has a value equal to 1/3.
Hence the ratios are equivalent fractions.
