Answer:
C. 6 gallons < 25 quarts.
E. 80 pints = 40 quarts.
Step-by-step explanation:
A. There are 8 fluid oz in 1 cup.
Multiply 8 with 6:
6 cups x 8 = 48 fl oz.
44 fl oz < 48 fl oz ∴ A. is false.
B. There are ~6.67 pints in 1 gallon.
Multiply 6 gallon with 6.67:
6 gallon x 6.67 = ~40.02 pint.
47 pint > 40.02 pint ∴ B. is false.
C. There is 4 quarts in 1 gallon.
Multiply 6 gallons with 4:
6 gallon x 4 = 24 quarts.
24 quarts < 25 quarts ∴ C. is true.
D. There is 4 cups in 1 quarts.
Multiply 7 with 4 and add 4:
7 quarts x 4 = 28 + 4 = 32
32 cups < 34 cups ∴ D. is false.
E. 1 quart = 2 pint
You are given 80 pints:
80/2 = 40 quarts ∴ E. is true.

Step-by-step explanation:
Since he two are similar you need to make a ratio of the two parallelograms
The first tells you side FE is 2 and side EH is 3 so write it like this 2/3.
Next you need to do the same thing with the second parallelogram, so you know side XW is 6 but you don't know side WZ so you'd write this one 6/x.
You can do this since FE is similar to XW, because it is the same shape just bigger.

Lauren mowed 3 lawns in 15 hours. What was her rate of mowing in hours per lawn?Lauren mowed 3 lawns in 15 hours. What was her rate of mowing in hours per lawn?
Answers
Answer:
5 hours per lawn
Step-by-step explanation:
15 hours divided by 3 lawns brings you to 5 hours per lawn.
The rate at which Lauren mows lawns is 5 hours per lawn, which means on average, it takes her 5 hours to mow one lawn.
Explanation:The question is asking us to find out how long, on average, it takes Lauren to mow one lawn given that she can mow 3 lawns in 15 hours. This is a classic problem of rate, specifically a rate of work. The formula we use for rate is simply: Rate = Total Work / Total Time. Here, the total work would be the 3 lawns that she mowed, and the total time would be the 15 hours. So, we divide 15 (total hours) by 3 (total lawns) to get the rate of mowing:
Rate = 15 / 3 = 5 hours per lawn.
This means that, on average, it takes Lauren 5 hours to mow a single lawn.

By accident, 6 burned out bulbs have additionally been mixed in with 26 good ones. Ken is replacing
old bulbs in his house. If he selects two bulbs at random from the box of 32, what is the probability
they both work?
Answers
The probability of randomly selecting two good bulbs is equal to 0.665.
How to find the probability?
So, we have a set of 32 bulbs, such that 26 are good and 6 are burned.
The probability of randomly selecting one good bulb is equal to the quotient between the number of good bulbs and the total number of bulbs.
It gives:
P = 26/32
Now, for the next bulb, the probability is computed in the same way, but now there are 25 good bulbs and 31 in total, so the probability is:
P' = 25/31
The joint probability is given by the product between the two individual probabilities:
p = (26/32)*(25/31) = 0.655

A bag contains 5 red, 4 green, and 3 blue marbles. What is the probability of randomly picking a green marble, replacing it, and then randomly picking a blue marble?
Answers
Final answer:
The probability of first picking a green marble, replacing it, and then picking a blue marble from a bag containing 5 red, 4 green, and 3 blue marbles is 1/12.
Explanation:
The question is about calculating the probability of selecting a green marble and then a blue marble from a bag with a replacement in between the picks. The process involves two independent events since the green marble is replaced before picking the blue marble.
To calculate the probability of picking a green marble first, we consider the total number of marbles and the number of green marbles. Given there are 5 red, 4 green, and 3 blue marbles, the total number of marbles is 5+4+3=12. The probability of picking a green marble is thus 4/12 or 1/3. Because we replace the green marble, the bag's contents remain the same for the second pick.
The probability of picking a blue marble after replacing the green marble is therefore based on the same total of 12 marbles. The probability is 3/12 or 1/4. Now, since these are independent events, we multiply the two probabilities together to get the overall probability of both events happening in sequence: (1/3) * (1/4) = 1/12.
In summary, the probability of first picking a green marble, replacing it, and then picking a blue marble is 1/12.
Final answer:
The probability of randomly picking a green marble, replacing it, and then randomly picking a blue marble is 1/12.
Explanation:
To find the probability of randomly picking a green marble, replacing it, and then randomly picking a blue marble, we need to first calculate the individual probabilities.
The bag initially contains 5 red, 4 green, and 3 blue marbles. The probability of picking a green marble is 4/12, since there are 4 green marbles out of a total of 12 marbles.
Since the first marble is replaced, the bag still contains the same number of green marbles, so the probability of picking a blue marble on the second draw is also 3/12, since there are 3 blue marbles left out of 12 marbles.
To find the probability of both events happening, we multiply the individual probabilities: (4/12) * (3/12) = 1/12.

What is 0.¯42 expressed as a fraction in simplest form?
Answers
Answer:
Part B (solution): For 0.42... (with the two repeating forever), we need to break up the decimal into the part that does not repeat and the part that repeats.
For the part that does not repeat, pretend that the repeating part is not there (so you have 0.4). Then think about place value. The non-repeating part of this decimal (0.4) is 4 tenths, so write that as a fraction: 4/10.
For the part that repeats, pretend the part that does not repeat is not there (so you have 0.2....). Use the rule of 9s, which tells you to put the repeating part (2) over a nine for every place value that is repeating. In this case there is only one repeating place value (again, 2), so we have 2/9. However, since we skipped a place value (the 4 in our given problem), we need to multiply that place value (in this case 1/10) by 2/9, which is 2/90. Finally, we need to add that to 4/10. Make sure your answer is simplified. Click HERE for help on Question 1.
Part C (solution): For 0.42... (with the four AND two repeating forever), use the rule of 9s. The rule of 9s tells you to put the repeating part (42) over a nine for every place value that is repeating. In this case there is two repeating place values, so we have 42/99.

Part A - (work for √5): Approximate the value of √5 to the nearest tenth. 5 is between the perfect squares 4 and 9. So √5 is between 2 and 3. The distance from 4 to 5 is 1. The distance from 4 to 9 is 5. The ratio is 1/5, or .2. So, √5 is about .2 bigger than 2. Click HERE for help on Question 3.
Part A - (work for 2√5): Approximate the value of 2√5 to the nearest tenth. 5 is between the perfect squares 4 and 9. So √5 is between 2 and 3. The distance from 4 to 5 is 1.

The fraction representation of 0.¯42 in simplest form is 14/33.
To express the repeating decimal 0.¯42 as a fraction in simplest form, we can use a mathematical technique.
Let's represent the repeating decimal as x = 0.¯42.
To remove the decimal part, we can multiply both sides of the equation by 100 (to move the decimal point two places to the right):
100x = 42.¯42.
Next, we subtract the original equation from the one multiplied by 100 to eliminate the repeating part:
100x - x = 42.¯42 - 0.¯42.
Simplifying both sides gives:
99x = 42.
Now, we can divide both sides of the equation by 99 to isolate x:
x = 42 / 99.
To simplify the fraction 42/99, we can find the greatest common divisor (GCD) of 42 and 99 and divide both the numerator and the denominator by it.
The GCD of 42 and 99 is 3:
42 = 3 x 14,
99 = 3 x 33.
Dividing both sides by 3 gives:
42 / 99 = (3 x 14) / (3 x 33) = 14 / 33.
Therefore, the fraction representation of 0.¯42 in simplest form is 14/33.
