lilah's band had practiced 24 songs. at a performance, they played 7 songs in their first set and 8 in their second set. how many songs did they have for their third set, if they had to save one song for an encore?
For the third set, they had 9 songs, but one was saved for an encore, so they had 8 songs remaining.
If Lilah's band had practiced 24 songs and they played 7 songs in their first set and 8 songs in their second set,
find out how many songs they had for their third set by subtracting the songs played in the first two sets from the total number of songs they practiced.
Total songs practiced = 24
Songs played in the first set = 7
Songs played in the second set = 8
Total songs played in the first two sets = 7 + 8 = 15
Now, to find the number of songs they had for their third set, subtract the songs played in the first two sets from the total songs practiced:
Number of songs for the third set = Total songs practiced - Total songs played in the first two sets
Number of songs for the third set = 24 - 15
Number of songs for the third set = 9
However, they had to save one song for an encore.
Therefore, they had 9 songs for their third set, but they played one for the encore, leaving them with 8 songs for the third set.

Peter flips a coin 50 times. What is the theoretical probability of flipping a heads?
an automobile tire loses t milliliters of tread traveling m miles. What is the independent variable?
In the given scenario, the independent variable is 'm miles', which is the controlled variable that dictates how much tread an automobile tire will lose, represented as 't milliliters'.
Explanation:In the situation described, an automobile tire loses t milliliters of tread traveling m miles. When analyzing this scenario, it's clear that the amount of tread lost depends on the distance traveled. Thus, the independent variable is the variable that you have control over or can set prior to the start of the experiment or observation, which in this case is m miles. The dependent variable, which changes in response to the independent variable, would be t milliliters of tread lost. As the car travels more miles, the amount of tread lost would likely increase, which shows a dependency of t milliliters on m miles.
A computer software store is having a sale. The table shows the regular price r and the sale price s of various items. Which formula can be used to calculate the sale price?
Final answer:
The formula to calculate the sale price of items on sale is s = r - (r × discount rate), where 's' is the sale price, 'r' is the regular price, and the discount rate is expressed as a decimal. An example illustrates the process for a $100 item with a 20% discount, resulting in a sale price of $80.
Explanation:
Generally, the sale price can be calculated by subtracting the discount amount from the regular price. The discount amount itself is often a percentage of the regular price. Therefore, if the discount rate is given as a percentage, the formula to find the sale price could be expressed as s = r - (r × discount rate). This is a simplification and assumes that the discount rate needs to be converted from a percentage to a decimal form before applying.
For example, if an item's regular price is $100, and there is a 20% discount, the calculation would be: s = 100 - (100 × 0.20) = $80. Hence, the sale price is $80. This formula is crucial for both customers and businesses to understand how much they save or earn respectively on sale items.
Lisa paid $43.95 for 16.1 gallons of gasoline what was the cost per gallon rounded to the nearest hundredth
Answer:
The cost per gallon of gasoline, rounded to the nearest hundredth is $2.73.
Step-by-step explanation:
The cost of 16.1 gallons of gasoline = $43.95
So, the cost of 1 gallon of gasoline is given by = [tex]\frac{43.95}{16.1}[/tex]
= $2.7298 rounded $2.73.
Therefore, the cost per gallon of gasoline, rounded to the nearest hundredth is $2.73.

if the Browns plant 3/16 tomatoes, 1/4cabbage, and 2/8pepper, what fraction of their garden will be unplanted?
Hence, the fraction of their garden will be unplanted is [tex]\frac{5}{16}[/tex].
What is the simplification?
Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
Here given that,
If the Browns plant [tex]\frac{3}{16}[/tex] tomatoes, [tex]\frac{1}{4}[/tex] cabbage, and [tex]\frac{2}{8}[/tex] pepper.
So,
The unplanted plants are [tex]\frac{5}{16}[/tex].
[tex]\frac{3}{16}+\frac{1}{4}+\frac{2}{8}\\\\=\frac{3+4+4}{16}\\\\=\frac{11}{16}\\\\[/tex]
Then, the fraction of their garden will be unplanted
[tex]\frac{16}{16}-\frac{11}{16}=\frac{5}{16}[/tex]
Hence, the fraction of their garden will be unplanted is [tex]\frac{5}{16}[/tex].

jax has 6 marbles his sister has 3 times as many as jax
Jax's sister has 3 times as many marbles as Jax. By using multiplication, we calculate that if Jax has 6 marbles, his sister, therefore, would have 18 marbles.
Explanation:In this problem, Jax's sister has 3 times as many marbles as Jax. If Jax has 6 marbles, we get the number of marbles that his sister has by multiplying 6 with 3. That's because we're given that she has 3 times the amount of marbles that Jax has.
So, the calculation would be 6 * 3 = 18. Therefore, Jax's sister has 18 marbles. The principle used here is multiplication in basic arithmetic. It's a method of scaling quantities based on given ratios or proportions. In this case, the ratio given was '3 times as many'.

In the car lot,4/12 of the cars are white and 3/12 of the cars are blue.What fraction of the cars in the lot are either white or blue?
The fraction of the cars in the lot are either white or blue is 7/12.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, in the car lot, 4/12 of the cars are white and 3/12 of the cars are blue.
Either white car or blue car means sum of white and blue car
Now, 4/12 + 3/12
= (4+3)/12
= 7/12
Therefore, the fraction of the cars in the lot are either white or blue is 7/12.
