Ana uses 3/4 cup of china juice for every 1/3 cup of lemon juice to make a soda. What is the ratio of cups of china juice to cups of lemon juice?
<u>Solution</u>
To find the ratio of cups of china juice to cups of lemon juice, we divide
by
and simplify.
We set up the division as follows:
Multiply the first fraction by the reciprocal of the second fraction.
This gives us;
We then obtain:
Therefore the ratio of cups of china juice to cups of lemon juice is 9:4
If that is all the question is asking, simply solve the problem.
Divide 8 cars by 4 hours, giving you 2 cars every hour.
Answer:
5 + 4 - (8 * 3 - 22)⁴ * 4 = -55
Step-by-step explanation:
5 + 4 - (8 * 3 - 22)⁴ * 4
Follow PEMDAS which states you need to do equations in the order of:
Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.
Knowing this, simplify inside the parenthesis by multiplying 8 and 3 first.
5 + 4 - (24 - 22)⁴ * 4
Now subtract 22 from 24 inside the parenthesis.
5 + 4 - (2)⁴ * 4
Since we are done with parenthesis, move on to the next part of PEMDAS which says to do exponents next. Take 2 to the power of 4.
5 + 4 - 16 * 4
Now that we are done with exponents, move on to the next part of PEMDAS which says to multiply/divide next. Multiply -16 and 4.
5 + 4 - 64
Now that we are done with multiplication/division, move on to the last part of PEMDAS which says to add/subtract. Add 5 and 4.
9 - 64
Finally, subtract 64 from 9 to get:
-55.
Probability of choosing a black fly = 30/100 = 0.3
Probability of choosing a grey fly = 70/100 = 0.7
So, probability of choosing 2 grey flies = 0.7*0.7 = 0.49
