The correct answer is $15
Explanation:
The first step is to determine the total of oil that was used for the 5 batches. To find this, you just need to multiply the amount of oil used for one batch by the total batches.
1 cup of oil per batch x 5 batches = 5 cups of oil
This means, in the 5 batches the oil Dinesh used was 5 cups of oil. Additionally, you know the total of cups in the bottle of oil is 12 cups, and these 12 cups or total costs $36. Now to find what is the cost of the 5 cups use the rule of three and cross multiplication.
12 cups of oil = $36 1. Write the values
5 cups of oil = x
12 x = 180 2. Cross multiply this means 36x 5 and 12 multipy by x
x = 180 ÷ 12 3. Solve the equation
x= 15 - Cost for 5 cups used in the batches
Answer: 8 cups
Step-by-step explanation:
Let the cups of orange juice concentrate that he used be represented by x.
Therefore, based on the information, we can form an equation which will be:
2/5 = x/20
Cross multiply
5 × x = 2 × 20
5x = 40
x = 40/5
x = 8
Therefore, he used 8 cups of orange juice concentrate.
2x-2x+4=6
4=6
and since there's no such things im gonna say D.no solution
Substituting z = 5 into the first equation:
2x - y + 5 = -4
y = 2x + 9
Substituting y and z into the third equation
-2x + 3(2x + 9) - 5 = -10
4x + 27 = -5
x = -8
y = 2(-8) + 9 = 7
z = 5
Answer:
1/6
Step-by-step explanation:
The six sided die has a total of 6 possible outcomes with red being only one of them. Therefore, this means that in a single dice roll the probability of it being red would be 1/6. Since, the question asks the probability of at least one red outcome, the second roll can be anything. Therefore, the probability of the second roll would be 6/6 or 1 and if we multiply this by the probability of the first roll it would stay the same. Meaning that the probability of getting atleast one red outcome in two rolls would be 1/6
