In the chemistry lab an experiment requires 500ml of one ingredient to be mixed with 1,000 ml of another. How many liters is the solution
After mixing 500 ml with 1,000 ml, the total volume of the solution is 1.5 liters.
Explanation:To find out how many liters the solution is after mixing 500 ml with 1,000 ml, you simply add the volumes together and convert to liters. First, you have a total volume of 500 ml + 1,000 ml = 1,500 ml. Now, notice that you are going from a smaller unit (milliliters) to a larger unit (liters). Since there are 1,000 milliliters in a liter, you will need to divide by 1,000:
1,500 ml ÷ 1,000 = 1.5 liters.
Therefore, the solution will have a total volume of 1.5 liters.

Greg is opening a car wash. He estimates his cost equation as C = 9000 + 0.09x and his revenue equation as R = 1.85x, where x is the number of cars washed in a six-month period. Find the number of cars that must be washed in a six-month period for Greg to make a profit.
9000+0.09x = 1.85x
subtract 0.09x from each side
9000 = 1.76x
divide both sides by 1.76
x = 9000/1.76
x = 5113. 64
he needs to wash 5114 cars to make a profit.

A) 80
B) 100
C) 130
D)120
130 +145 +65+160+120 = 620

6. z=2a-p
7. w= A/L
8. w= v/Lh
9. t= (A-P)/PR
Solve for x and y please !!
since both inside angles are 45, the height and the base would be the same
the height is 72 yd
so the base (y) would also be 72 yd
Y = 72
and x would equal y * sqrt(2)
so x = 72sqrt(2)

Chuy wants to buy a new television. The television costs $1,350. Chuy decides to save the same amount of money each week, for 27 weeks. After 8 weeks Chuy saved $440. Which of the following conclusions can you make about Chuy's plan?
a. Chuy has a good plan and will have exactly $1,350 saved at the end of 27 weeks.
b. Chuy must increase the amount he saves each week in order to meet his goal at the end of 27 weeks.
c. Chuy will save more than he needs and will meet his goal in less than 27 weeks.
d. There is not enough information given to make a conclusion about Chuy's plan.
Answer:
Option C. is correct.
Step-by-step explanation:
Chuy needs $1,350 to buy a new television.
he decides to save the same amount of money each week for 27 weeks.
In 8 weeks Chuy saved = $440
In 1 week Chuy saved $440 ÷ 8 = $43.00
Therfore, in 27 weeks Chuy can save = 43.00 × 27 = $1485.00
Chuy can save $1485.00 in 27 weeks that is more than he needs.
So Option c. would be correct Chuy will save more than he needs and will meet his goal in less than 27 weeks.

A quiz consists of 20 multiple-choice questions, each with 5 possible answers. for someone who makes random guesses for all of the answers, find the probability of passing if the minimum passing grade is 60 %.
To find the probability of passing the quiz, we need to determine the minimum number of correct answers needed to achieve a passing grade. The probability of guessing the correct answer for each question is 1/5, so the probability of getting exactly 12 correct answers is calculated using the binomial probability formula.
Explanation:To find the probability of passing the quiz, we need to determine the minimum number of correct answers needed to achieve a passing grade. Since a passing grade is 60%, this corresponds to 12 correct answers out of 20. The probability of guessing the correct answer for each question is 1/5, so the probability of getting exactly 12 correct answers is given by the binomial probability formula:
P(X = k) = (nCk) * p^k * (1-p)^(n-k)
Using this formula, we can calculate the probability of passing the quiz.

The problem can be solved using binomial distribution principles where the number of trials is the total number of questions (20), success is answering a question correctly, and the probability of success is 1/5 since the answers are guessed randomly. Calculate the cumulative binomial probability for getting 12 (minimum passing grade at 60%) to 20 (total questions) correct answers. This gives the probability of passing the test.
Explanation:The question asks about the probability of passing a 20 question quiz with each question having 5 possible answers, by making random guesses. To pass the quiz, a grade of 60% is required which means at least 12 questions need to be answered correctly. Since the answers are guessed randomly, the chance of picking the correct answer for each question is 1/5 or 0.2.
We can treat this problem as a binomial distribution problem, where the success is answering a question correctly. In this case, the number of trials is n=20 (the total number of questions), the number of success k is 12 or more (the minimum number of correct answers required to pass), and the probability of success p is 0.2 (since there are 5 multiple choice options per question).
Calculating the cumulative binomial probability for k=12 to n=20, we get the required probability of passing the test. Given that we have to calculate multiple probabilities and sum them, this problem might be easier to solve if you have statistical software or a calculator that can compute binomial distributions.
