How many gallons of punch will sadie make?

Answers

Sadie will make 3 gallons of punch.


First, let's convert all the measurements to the same unit, such as gallons.

1 gallon = 4 quarts

1 gallon = 8 pints

1 gallon = 16 cups

Now, let's convert each ingredient:

1. Lemon-lime juice: 8 quarts = 8/4 = 2 gallons

2. Vanilla ice cream: 4 pints = 4/8 = 0.5 gallons

3. Orange juice: 8 cups = 8/16 = 0.5 gallons

Now, let's sum up the amounts of each ingredient:

2 gallons (lemon-lime juice) + 0.5 gallons (vanilla ice cream) + 0.5 gallons (orange juice) = 3 gallons

Complete question: Using 8 quarts lemon-lime juice , 4 pints vanilla ice cream , 8 cups orange juice .How many gallons of punch will Sadie make?

So you have:

1) Start off by multiplying both sides by x to simplify the problem:
[tex]\frac{3}{x} + 2 = \frac{2}{x} - 1 \\ x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\ 3 + 2x = 2 - x [/tex]

2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
[tex]3 + 2x = 2 - x\\ 3x = -1[/tex]

Sarawong is carrying six pages of math homework and four pages of english homework. a gust of wind blows the pages out of his hands and he is only able to recover seven random pages. what is the probability that he recovers at least five pages of his math homework

Answers

Final answer:

The probability that Sarawong recovers at least five pages of his math homework is 56.6%, using the combinatory principles of probability.

Explanation:

To solve the problem, we need to calculate the probability that Sarawong recovers at least five pages of his math homework after a gust of wind blows the pages out of his hands. This is a probability problem, which is under the field of mathematics. We first need to understand the total possibilities of the pages he could recover, which is combinations of six math pages and four English pages, that is 10 pages pick 7 pages. We add up the probabilities that he recovers 5, 6, or all 7 math pages. We also need to consider that there is no particular order in which the pages are recovered.

The total number of ways to select 7 pages from 10 can be calculated by 10 choose 7, which is 120.

The number of ways to select 5 math pages out of 6 and 2 English pages out of 4 is 6 choose 5 times 4 choose 2, which equals 60. The probability of this case is 60 / 120 which is 0.5.

The number of ways to select 6 math pages and 1 English page is 6 choose 6 times 4 choose 1, which is also 4. The probability is 4 / 120 which is 0.033.

The number of ways to select all math pages is 6 choose 6 and 4 choose 1, which totals 4. The probability is also 4 / 120 which is 0.033.

Therefore, the total probability that Sarawong recovers at least 5 of his math pages is 0.5 + 0.033 + 0.033 = 0.566, or 56.6%. This is the mathematical solution to the problem.

The scores on an exam are normally distributed with a mean of 74 and a standard deviation of 7. What percent of the scores are greater than 81?

A. 50%

B. 13.5%

C. 84%

D. 16%

Answers

The difference between 81 and the mean is 
   81 - 74 = 7
This is exactly the value of the standard deviation. You know that the "empirical rule" tells you 68% of all scores lie within 1 standard deviation of the mean. That tells you 32% of all scores lie beyond 1 standard deviation from the mean.

The normal distribution is symmetrical, so half of those (16%) lie above 1 standard deviation above the mean; the other half (16%) lie below 1 standard deviation below the mean. We're only concerned with the first group—those scores above 1 standard deviation above the mean.

The appropriate choice is

The maximum width of the slot is 25cm (Option A).

To find the maximum width of the mail slot, we need to calculate the length of the diagonal (the dotted line) in the rectangle. The diagonal of a rectangle can be found using the Pythagorean theorem.

Given:

- The length of the rectangle (one side) = 24 cm

- The height of the rectangle (other side) = 7 cm

The formula for the diagonal [tex]\( d \)[/tex] is:

[tex]\[ d = \sqrt{(length)^2 + (height)^2} \][/tex]

Substituting the given values:

[tex]\[ d = \sqrt{24^2 + 7^2} \][/tex]

[tex]\[ d = \sqrt{576 + 49} \][/tex]

[tex]\[ d = \sqrt{625} \][/tex]

[tex]\[ d = 25 \, \text{cm} \][/tex]

So, the maximum width of the mail slot is 25cm.

If Dr. Suzuki rides his bike to his​ office, he averages 9 miles per hour. If he drives his​ car, he averages 27 miles per hour. His time driving is one third hour less than his time bicycling. How far is his​ office?

Answers

Speed
Riding speed = 9 mph
Driving speed = 27 mph

Time
If x hours is the time taken when riding, (x - 1/3) hours  is the time taken when driving.

Distance in both instances is the same, D= Speed * time

Therefore,
9*x = 27(x-1/3)
9x = 27x - 27/2
9x = 27x - 9
(9-27)x = -9
-18x = -9
x = 9/18 = 1/2 hours

Distance, D = 1/2 *9 = 4.5 miles

When flying at an altitude of 5 miles, the lines of sight to the horizon looking north and south make about a 173.7 degree angle. how much of the longitude line directly under the plane is visible from 5 miles high?

Answers

Final answer:

To find the visible part of the longitude line from an altitude of 5 miles, we can use the Law of Sines in combination with the given angle of 173.7 degrees. The resulting arc length signifies what portion of the Earth is visible from this altitude.

Explanation:

This question pertains to plane geometry and spherical geometry. Given that the angle formed by the lines of sight to the northern and southern horizons is 173.7 degrees when flying at an altitude of 5 miles, we can find the visible part of the longitude line using the Law of Sines.

Imagine a figure with a central angle of 173.7 degrees and a radius of 5 miles (the altitude of the airplane). Here, the radius of Earth is 3959 miles. Thus, from the center of the Earth to the airplane is a total of 3959+5 = 3964 miles.

Using the law of sines, we have: (sin(173.7 deg) / s) = (1 / 3964). Simplifying this gives us the arc length, s, which is the visible part of the longitude line. This visible part signifies the portion of the Earth you can see from the airplane's perspective.

Final answer:

Using the horizon line formula, D = 112.88 km x √h, where h is the height in kilometers, we can determine the length of the longitude line visible from 5 miles up. This calculation takes into account, but barely modifies for not looking at a perfect 180-degree angle.

Explanation:

In order to find out how much of the longitude line directly under the plane is visible from 5 miles high, we need to apply some mathematical and geographical concepts. The key concept here is the idea of the horizon line, which is the furthest point you can see from a given point of elevation.

Using the formula D = 112.88 km x √h, where h is the height in kilometers (in this case, 5 miles or approximately 8.05 km), you would calculate D = 112.88 km x √8.05. This calculation gives you the distance to the horizon or how much of the line directly beneath the plane is visible.

However, the student's question also mentions an angle of 173.7 degrees - it represents nearly a complete observable circle from the airplane (as 180 degrees would be a complete straight line view). So, the observable part of longitude from the plane will also be correspondingly reduced by a very small amount, since we are not looking at a perfect 180 degrees.

To express ln x + a ln y - b ln z as a single logarithm, use the properties of logarithms.

Explanation:

To express ln x + a ln y - b ln z as a single logarithm, we will use the properties of logarithms. The key properties we will use are:

ln xy = ln x + ln y: The logarithm of a product is the sum of the logarithms of the factors.ln (x/y) = ln x - ln y: The logarithm of a quotient is the difference of the logarithms of the numerator and denominator.

Using these properties, we can simplify the expression:

ln x + a ln y - b ln z = ln x + ln(y^a) - ln(z^b)= ln (x(y^a)/(z^b))
