Answer:
To find the unit rate, we divide the total cost by the total number of ounces:
Unit rate = total cost ÷ total number of ounces
Unit rate = $3.79 ÷ 19.5 ounces
Unit rate = $0.194 per oz.
Rounding to the nearest cent, the unit rate is $0.19 per oz.

Four swimmers are training for a relay race. Each day they practice by swimming at least 1,600 yards total. The friends evenly divide the number of yards they swim.
Write and solve an inequality to determine how many yards each friend will swim. Show all your work.
The expression 9.00x+4.50y represents the total amount of money Harriet earns at her two jobs, where x represents the number of hours worked at job X and y represents the number of hours worked at job Y. Which shows an equivalent expression to the given expression and correctly describes the situation?
4.50(2x+y), which shows that Harriet earns twice as much per hour at job X than job Y.
4.50(2x+y), which shows that Harriet earns 4.50 times as much per hour at job X than job Y.
13.50xy, which shows that Harriet earns $13.50 each hour she works.
13.50xy, which shows that Harriet earns $13.50 every two hours she works.

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
1÷4 x³ = –27÷4
1. First, divide both sides of the equation by 4.
1÷4 x³/4 = –27/4/4
2. Next, on the left side of the equation, use inverse operations to get rid of the division. This will give us x³ = –27.
3. Then, to solve for x, take the cube root of both sides of the equation.
Cube root of x³ = cube root of –27
4. To check your answer, plug in -3 for x in the original equation and solve.
1÷4 x³ = –27/4
1÷4 (-3)³ = –27/4
1÷4 (-27) = –27/4
1 = 1
Since 1 = 1, the answer checks out.
Therefore, the solution to the equation is x = -3.

★ / travis is swimming 3.25 feet below the surface of the
water . connor is swimming 5.75 feet below the surface
of the water. how far apart are travis and connor ?
Answer:
1: 4.5 cups of flour
2: 12.125 ft of rope
3: 68.5 inches above ground
4: 21.3333..... ounces of water
5: 2.5 ft below the surface
Step-by-step explanation:
1: 8.25-3.75=4.5
2: 15.5-3.375=12.125
3: 92.75-24.25=68.5
4: (259÷12)-.25=21.33333.....
5: 5.75-3.25=2.5

Please could someone help me?
Answer:
The large box weighs 61/4 Kg and the small box weighs 25/4 Kg
Step-by-step explanation:
Assume the large box is x and the small box is y
6x+2y=104, 3x+5y=77 therefore, 6x+2y=104, 6x+10y=154
8y=54 y=25/4 x=61/4

What is the most appropriate measure of center for the data set about 7th graders?
A)mean
B)median
C)range
D)IQR
Answer:
The most appropriate measure of center for the given data set about 7th graders is the median (option B).
Step-by-step explanation:
The median is the middle value in a data set when the values are arranged in ascending or descending order. It is not affected by extreme values or outliers. There is an outlier in this case (180), which could alter the mean and represent the data inaccurately. The range does not give a measure of center but instead represents the spread of the data. The IQR is a valuable measure for understanding the spread of data and identifying potential outliers but is not suitable for describing the central tendency or average of the data.

Compare the theoretical and experimental probabilities. Jayson draws a card from a deck, replaces it, and draws again. He records the number of times he draws a queen.
Number of Trials: 20, 25, 100
Number of Queens: 5, 3, 9
The theoretical probability is: ?%
ANSWER:divide 20/5, 25/3, 100/9 those answers are: 4, 8.3, 11.1. All we really need is 100/9=11.1 because it wants a percent so the answer is 11.1%
The statement that is false on Jose drawing cards from the deck is B. For a given number of selections, we can use Joseph's graph to find the number of diamonds that he has picked so far.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Jose draws a card from a deck replaces it and draws again he records a number of times he draws an ace. He decides to record the total number of aces that he selects and calculates the proportion of aces that he has selected so far after each pick. He then constructs a graph to visualize his results.
as the graph can not be used:
Jose only recorded the number of aces he selected, not the number of diamonds. Therefore, we cannot use his graph to find the number of diamonds he picked.
However, if we were to use the graph to find the number of aces that Jose has picked so far, then we would be successful. The other statements are true as Jose recorded the cards he took and the cards were replaced after each pick.
