If we set up the rate given now, in a money/ounce format, it will be written like this:
$3.49 / 12 oz.
Because we're trying to find how much one ounce will cost (unit rate), we must divide $3.49 by 12 oz.
When dividing, you will get $0.29083....., which can be rounded to $0.29
The unit rate per ounce is $0.29.
Answer:
$3.49 / 12 oz.=0.29

Answer:
Two color drawings and seven black and white drawings.
Step-by-step explanation:
If it takes 25 minutes for a color drawing it would take him 50 minuies to do two, leaving him with a remainder of 70 minutes. In that time he can create 7 black and white drawings. 7+2=9, giving you your answer.
To determine the number of black and white and color drawings, set up a system of equations based on the given information. Solve the system of equations by adding them together. The solution is 3 black and white drawings and 6 color drawings.
To solve this problem, we can set up a system of equations. Let the number of black and white drawings be represented by x and the number of color drawings be represented by y.
The first equation is based on the fact that it takes Akira 10 minutes to make a black and white drawing and 25 minutes for a color drawing. So, the total time spent on black and white drawings is 10x minutes and the total time spent on color drawings is 25y minutes.
The second equation states that on Saturday Akira made a total of 9 drawings in 2 hours, which is equivalent to 120 minutes. So, we have x + y = 9.
Adding the equations 10x + 25y = 120 and x + y = 9, we can solve for x and y. Solving this system of equations gives us x = 3 and y = 6.

750+250x<2500
Subtract 750 from both sides.
250x<1750
Divide both sides by 250.
x<7
The most hours that they can do is 7, or it can be less.
Answer:
x = 7
Step-by-step explanation:
x= number of hours
"cost is not exceed $2500 per day"
not exceed = less than
750+250x < 2500
250x< 2500-750
250x < 1750
x < 1750/250
x<7

Answer: ~ 34.15%
Step-by-step explanation:
To calculate the percent error for the amount of snowfall, you can use the following formula:
Percent Error = [(|Estimated Value - Actual Value|) / Actual Value] * 100%
In this case, the estimated snowfall is 6.75 inches, and the actual snowfall is 10.25 inches. Plugging these values into the formula:
Percent Error = [(|6.75 - 10.25|) / 10.25] * 100%
Percent Error = [(3.5) / 10.25] * 100%
Percent Error ≈ 34.15%
So, the percent error for the amount of snowfall is approximately 34.15%. This means that the estimated snowfall was about 34.15% lower than the actual snowfall.
