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.

The fraction of the cars in the lot are either white or blue is 7/12.

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.

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'.

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.

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.

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.

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'.

The simplified ratio of 36 to 45 is 4 to 5.

To simplify the ratio 36 to 45,

First, find the greatest common divisor (GCD) of 36 and 45 as

36 = 1, 2, 3, 4, 6, 9, 12

45 = 1, 3, 5, 9, 15 .

So, the GCD of 36 and 45 is 9.

Now, simplifying the ratio

= 36/48

= (9 x 4)/ (9 x 5)

= 4/5

Therefore, the simplified ratio of 36 to 45 is 4 to 5.

The original price of the cape, before a 30% discount that resulted in a sale price of $126, was $180. Since 70% of the original price equals the sale price, dividing $126 by 0.7 yields the original price.

To find the original price of an item that has been discounted by 30%, we first recognize that the sale price represents 70% of the original price because 100% - 30% = 70%. If $126 is the sale price, it is 70% of the original price.

To find 100% of the original price, you can set up a proportion or simply divide the sale price by 0.7.

Using division:

Original Price = Sale Price / 0.7
Original Price = $126 / 0.7
Original Price = $180

Therefore, the original price of the cape was $180.

When we include sales tax in the calculation, assuming we know the tax rate, we would add that to the original price to get the total cost that will be paid at the register.

However, this question doesn't provide a tax rate, so we only calculate the original price.

Answer:

Carter should measure two times the flour in the cup to obtain the quarter of cup he needs to the recipe.

Step-by-step explanation:

To solve this problem you should use a simple equation. As Carter has a cup that holds an eighth of the cup and he need to add a quarter cup to the recipe he needs to find a factor that multiplied by [tex]\frac{1}{8}[/tex] gives as result the [tex]\frac{1}{4}[/tex] he needs, that is:

1. Let´s name x the factor and we have the following equation:

[tex]\frac{1}{8}*x=\frac{1}{4}[/tex]

2. Solving for x:

[tex]\frac{x}{8}=\frac{1}{4}[/tex]

[tex]x=\frac{8}{4}[/tex]

[tex]x=2[/tex]

The result x=2 means that Carter should measure two times the flour in the cup to obtain the quarter of cup he needs to the recipe.
