Which point on the graph shows the price of 6 ounces of cheese? Use the formula y=x÷2 to find y when x is 6.
Answers
Using the formula y = x ÷ 2, the price for 6 ounces of cheese is calculated to be $3, following the linear price-quantity relationship given.
To find the price of 6 ounces of cheese, we can use the formula y = x ÷ 2.
Plugging in x = 6 ounces into the formula, we get:
y = 6 ÷ 2 = 3.
So the price y for 6 ounces of cheese is $3.
This is consistent with the given information that also indicates a linear relationship between the amount of cheese and its price (e.g., 2 ounces for $1 and 14 ounces for $7).
The probable question may be:
Which point on the graph shows the price of 6 ounces of cheese? Use the formula y=x÷2 to find y when x is 6.
Amount of cheese x is 2 ounces the price y is 1 $.
Amount of cheese x is 6 ounces the price y is _____ $.
Amount of cheese x is 7 ounces the price y is 3.5 $.
Amount of cheese x is 14 ounces the price y is 7 $.

Overnight the temperature dropped 1.3 degrees every hour how many hours did it take the temperature to drop 7.8 degrees
Answers
To calculate how long it took for the temperature to drop 7.8 degrees at a rate of 1.3 degrees per hour, divide 7.8 by 1.3, which equals 6 hours.
Explanation:This problem can be solved using simple division. The question tells us that the temperature dropped 1.3 degrees every hour and we want to know how long it took for the temperature to drop 7.8 degrees. So, divide the total drop in temperature (7.8 degrees) by the rate of temperature drop (1.3 degrees per hour).
7.8 / 1.3 = 6
So, if the temperature dropped 1.3 degrees every hour, it would take 6 hours for the temperature to drop 7.8 degrees.

David was given two coins. One coin is twice the value of the other. Which statement is not true
David was given $0.75.
David was given $0.26.
One coin is smaller in size than the other
David was given $0.15.
Answers
Final answer:
The statement 'David was given $0.26' is not true because U.S. currency does not include the necessary coins where one coin is twice the value of the other to make up $0.26.
Explanation:
David was given two coins, where one coin is worth twice the value of the other. We need to identify which statement is not true among the given options regarding the value of the coins David was given. Let's analyze each statement:
If David was given $0.26, he could have a 10 cent coin and a 16 cent coin, which isn't possible because U.S. currency does not include a 16 cent coin.Receiving $0.75 would mean having coins of values $0.25 and $0.50, which is possible.Having a total of $0.15 would mean the coins are $0.05 and $0.10, again, this is possible.The statement about one coin being smaller in size than the other does not necessarily relate to their values, as coin size and value are not directly correlated.
Only the statement about being given $0.26 cannot be true, because U.S. currency does not include the necessary coins to satisfy the condition where one coin is twice the value of the other.

On a hike, each hiker carries the items shown. Write an expression in simplest form that represents the weight (in pounds) carried by x hikers. Interpret the expression.
Answers
The expression representing the weight carried by x hikers is the weight carried by one hiker multiplied by x. Due to a lack of specific weight information for one hiker, the general expression can be 'wx' where w is the weight per hiker.
To create an expression that represents the weight carried by x hikers, we need to know the weight each hiker carries individually. However, the necessary information to calculate that weight is not provided in the details of the question. If we had this information, the expression would be simply the weight carried by one hiker multiplied by x, where x is the number of hikers. For example, if one hiker carries 5 pounds, the expression for x hikers would be 5x pounds.
Interpreting the expression '5x' would mean that the total weight carried by the group of hikers is 5 pounds multiplied by the number of hikers. If there were, for example, 3 hikers, they would be carrying a total of 15 pounds together.
This general approach can be applied to any number representing the weight one hiker carries: if each hiker carries 'w' pounds, the expression for x hikers would be wx.

The answer to your question is $3006.88. They key word in the problem is per hour and if you see that word that means you usually multiple. So 42.5*70.75= 3006.875 or about 3006.88
The total earning for Teo is $3006.88 if teo worked for 42.5 h at $70.75 per hour, the answer is 3006.88.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Teo worked for 42.5 h at $70.75 per hour.
Let x be the total earnings.
The value of x can be found as follows:
x = 42.5(70.75)
x = 3006.875
Or
x = 3006.88
Thus, the total earning for Teo is $3006.88 if teo worked for 42.5 h at $70.75 per hour, the answer is 3006.88.

What is a common denominator for 2/8 and 3/4 in simplest form?
Answers
The common denominator for 2/8 and 3/4 in simplest form is 8.
Explanation:To find a common denominator for fractions, you need to find the smallest multiple that both denominators can evenly divide into. In this case, the denominators are 8 and 4.
The multiples of 8 are: 8, 16, 24, 32, 40, ...
The multiples of 4 are: 4, 8, 12, 16, 20, ...
The first multiple that both denominators share is 8. Therefore, the common denominator for 2/8 and 3/4 in simplest form is 8.
Final answer:
The simplest common denominator for 2/8 and 3/4 is 4, since 2/8 simplifies to 1/4, and both fractions have 4 as a denominator.
Explanation:
Finding a common denominator for fractions is an essential skill in mathematics. We need this for adding, subtracting, or comparing fractions. To find a common denominator for 2/8 and 3/4, we look for the least common multiple (LCM) of the denominators.
Firstly, we simplify the fraction 2/8, which can be reduced to 1/4 because 2 divided by 2 is 1, and 8 divided by 2 is 4. Hence, we now have 1/4 and 3/4.
Since both denominators are now the number 4, which is the same, we can conclude that the simplest common denominator for 2/8 and 3/4 is 4.
In summary, multiplying and dividing by common factors helps us to simplify fractions and find common denominators efficiently. This principle is fundamental in fraction operations and is a useful skill in various mathematical contexts.
