Answer:

a=3/4

Step-by-step explanation:

1. Get 2/3a by itself.

•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.

•Because you only add and subtract like denominators

This will make it look like:

2/3a - 1/6 = 2/6

Then, add 1/6 to both sides to get 2/3a by itself.

It'll look like this:

2/3a = 3/6

2. Get a by itself.

•Multiply the reciprocal (opposite) of 2/3 to get a alone.

This will look like:

(3/2) • 2/3a = (3/2) • 3/6

a = 18/24

3. Simplify.

Find the largest number that can simplify the equation.

For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.

But the largest number you can divide both sides by is 6.

18 ÷ 6 = 3 and 24 ÷ 6 = 4.

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Answer:

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Step-by-step explanation:

Part A: To draw triangles ABC and DEC separately, follow these steps:

The lengths of sides BC, DE, and EC are as follows:

Part B: To find side AB of triangle ABC, we can use the concept of similarity and ratios. Since triangles ABC and DEC are similar, their corresponding sides are proportional. We can set up the following proportion:

AB/DE = BC/EC

Plugging in the given values, we get:

AB/1.2 = BC/2

To solve for AB, we can cross-multiply and then divide:

AB = (BC/2) x  1.2

Now we need to find the value of BC. We can use the Pythagorean theorem, as BC is the hypotenuse of triangle ABC. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

BC² = AB² + BE²

Plugging in the given value for BE, we get:

BC^2 = AB² + 0.3²

Now we can substitute the value of AB from the previous equation into this equation:

BC² = ((BC/2) * 1.2)² + 0.3²

Simplifying, we get:

BC² = 0.36 x BC^2/4 + 0.09

Multiplying both sides by 4 to eliminate the fraction, we get:

4 x  BC² = 0.36 x BC² + 0.36 + 0.09

Combining like terms, we get:

4 x  BC² = 0.36  BC² + 0.45

Subtracting 0.36 x BC² and 0.45 from both sides, we get:

3.64 x BC² = 0.45

Dividing both sides by 3.64 to isolate BC², we get:

BC² = 0.45 / 3.64

Taking the square root of both sides to solve for BC, we get:

BC ≈ √(0.45 / 3.64)

BC ≈ 0.357 feet

Now we can substitute the value of BC back into the equation for AB:

AB = (BC/2) x  1.2

AB ≈ (0.357/2) x  1.2

AB ≈ 0.214 feet

So, the approximate length of side AB of triangle ABC is 0.214 feet.

Answer:

702 pages

Step-by-step explanation:

1/3= 234

234*3=702

Answer:

351 pages

Step-by-step explanation:

If Henry still has 1/3 left that means that 234 was 2/3 of the book because 1/3 + 2/3 = 3/3 = The whole book.

To find out how many pages 1/3 is, we have to divide 234 by 2 because 234 is 2 thirds added together or 1 third multiplied by 2 and the inverse of that is divided by 2.

234 ÷ 2 = 117

So 1/3 is equal to 117 pages.

Like I said before 1/3 + 2/3 = 3/3 = The whole book.

117 is equal to 1/3 and 234 is equal to 2/3 so we add them together.

117 + 234 = 351

I hope that made sense.

Step-by-step explanation:

Perks A Lot typically sells more coffee per hour than Wide Awake.

What is mean?

The mean is a measure of central tendency that represents the average value of a set of numerical data. It is calculated by adding up all the values in the data set and dividing by the total number of values.

To determine which coffee shop typically sells the most amount of coffee per hour, we need to compare the measures of center for the two data sets. The two common measures of center are the mean and median.

The mean is calculated by adding up all the values and dividing by the total number of values. The median is the middle value when the data is arranged in order.

Using a calculator or spreadsheet, we can find the mean and median values for each coffee shop:

Perks A Lot:

Mean = (10+3.5+3+5+2.5+7+8+5.5+9.5+6+9+4.5) / 12 ≈ 5.75 gallons

Median = 5.75 gallons

Wide Awake:

Mean = (2.5+10+4+18+4+3+6.5+15+6+5+2.5) / 11 ≈ 4.5 gallons

Median = 4.5 gallons

From the calculations, we can see that Perks A Lot has a higher mean and median value than Wide Awake. Therefore, Perks A Lot typically sells more coffee per hour than Wide Awake.

Thus, we can use the mean or median as the measure of center to compare the two coffee shops, and both measures show that Perks A Lot typically sells more coffee per hour.

Answer: A. $30.00

Step-by-step explanation:

1. Find the common difference, or by how much the value changes per pound.   Divide the price of the sales by the amount of pounds to find the rate. The rate must be $2.50 since 10 ÷ 4 = 2.5. To confirm, use 2 or 3 pairs of values. 15 ÷ 6 = 2.5, which confirms that the common difference is 2.5. This means that every pound of asparagus is $2.5.

2. Now that the rate is known, multiply it by 12. 2.5 * 12 = $30.00, which is the final answer.

Each of these is proportional to the other. Meaning, if you put the price over the pounds, then you get a fraction that remains consistent throughout the entire table and beyond.

\(\frac{price}{pounds}=\frac{10}{4} =\frac{5}{2}\) so \(\frac{5}{2}\) will be our constant ratio. With our formula, we know that the two equal each other, so \(\frac{price}{pounds}=\frac{5}{2}\).

\(\frac{x}{10}=\frac{5}{2}\\\) so \(2x=50\\x=25\)

\(\frac{x}{12}=\frac{5}{2}\) so \(2x=60\\x=30\)

12 pounds of asparagus is $30.00

Answer:

Step-by-step explanation:

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:
