what is the shortest time it takes to collect a container of water

Hey there!

The first thing we can do is find the number of third in 4.

We can do this by multiplying 4 by 3 since there are 3 thirds in a whole.

4 x 3 = 12

So, 4 = 12/3

If she studies for 2/3 an hour each night, then we can divide 12 by 2 to figure out how many 2/3 go into 12/3.

12 ÷ 2 = 6

So, she studied for 6 days.

Hope this helps!

Answer:

x = 149

Step-by-step explanation:

Lines m and n are parallel lines as shown by the double arrows on each line.

The angles marked x and 149 deg are corresponding angles of parallel lines cut by a transversal.

Postulate:

If parallel lines are cut by a transversal, then corresponding angles are congruent.

According to the postulate above, since the angles marked 149 and x are corresponding angles, they are congruent.

x = 149

Answer:

X=149

7 * 2 = 14

10 and 4 make the product of 14.

10 + 4 = 14

Bilial factored 14y3 correctly.

Hiro factored 14y2 as (7y2)(2y)
Bilial factored 14y3 as (10y)(4y2)

To determine which one factored 14y3 correctly, we need to compare their factorizations to the original expression: 14y3. Hiro's factorization (7y2)(2y) does not match the original expression, as it is missing a y term. On the other hand, Bilial's factorization (10y)(4y2) matches the original expression.

Final answer:

To find the empty space in the can of tennis balls, calculate the volume of one tennis ball and multiply by three (since there are typically three balls per can), then subtract from the volume of the can. There are 43.54 inches³ of empty space in the can, after rounding to the nearest hundredth.

Explanation:

To calculate the empty space inside the can of tennis balls, we first need to determine the volume of one tennis ball and then the volume of the can. Given the radius of each tennis ball is 1.5 inches, we use the formula for the volume of a sphere:

V_ball = 4/3 π r³

Substitute with r = 1.5 inches and π = 3.14:

V_ball = 4/3 × 3.14 × (1.5 inches)³

V_ball = 4/3 × 3.14 × 3.375 inches³

V_ball = 14.13 inches³ (rounded to the nearest hundredth)

Next, we calculate the volume of the can, using the formula for the volume of a cylinder:

V_can = π r² h

Substitute with r = 1.75 inches and h = 9 inches:

V_can = 3.14 × (1.75 inches)² × 9 inches

V_can = 3.14 × 3.0625 inches² × 9 inches

V_can = 85.93 inches³ (rounded to the nearest hundredth)

The empty space within the can is therefore the volume of the can minus the volume of three tennis balls (assuming the can holds three balls):

Empty space = V_can - 3 × V_ball

Empty space = 85.93 inches³ - 3 × 14.13 inches³

Empty space = 85.93 inches³ - 42.39 inches³

Empty space = 43.54 inches³ (rounded to the nearest hundredth)

Therefore, there are approximately 43.54 inches³ of empty space inside the can.

Step-by-step explanation:

Do you mean:

(6^5/7^3)^2?

If so, you will get

6^10/7^6 or about 513.954016

It is to be note that  (6⁵ / 7³)² simplifies to become approximately 514.64

To simplify the expression (6⁵ / 7³)², we start by evaluating the exponents first.

6⁵ means 6 raised to the power of 5, which is 6 * 6 * 6 * 6 * 6 = 7776.

7³ means 7 raised to the power of 3, which is 7 * 7 * 7 = 343.

Now, we substitute these values back into the expression  -

(7776 / 343)² = (22.6666666667)² = 514.64197531

Therefore, it is right to state that (6⁵ / 7³)² simplifies to 514.64197531 which is approximately, 514.64.

Answer:

Step-by-step explanation:

The data values could be 10, 10, 10, 25, 25, 40.

Mean absolute deviation is defined as the average value of the absolute deviations from the mean.

Given that,

Mean absolute deviation of a set of 6 data values = 10

Let x1, x2, x3, x4, x5 and x6 be the data values.

Mean = 20

x1 + x2 + x3 + x4 + x5 + x6 / 6 = 20

x1 + x2 + x3 + x4 + x5 + x6 = 120

Also we have mean absolute deviation = 10

Data values could be 10, 10, 10, 25, 25, 40.

Mean = 20 and MAD = 10

Hence the data values could be 10, 10, 10, 25, 25, 40.

Answer:There will be 10 grams left because you subtract half of the current amount from it every 9 years.

Step-by-step explanation:

Starting with 40 grams of europium which has a half-life of 9 years, after the first half-life, there would be 20 grams left, and after the second half-life (a total of 18 years), there would be 10 grams remaining.

The question is about calculating the amount of a radioactive substance that remains after a certain period of time has passed, which is based on the substance's half-life. Given that the half-life of europium is 9 years, after one half-life (9 years) 50% of the substance would remain, and after two half-lives (18 years) only 25% would remain. Since we started with 40 grams of europium, we apply this decay process step by step:

Therefore, after 18 years, there will be 10 grams of the radioactive europium left.

Answer:

Step-by-step explanation:

Using the relation

Distance = speed × time

Change Jasmine's speed into an improper fraction

9 [tex]\frac{3}{10}[/tex] = [tex]\frac{93}{10}[/tex], then

distance = [tex]\frac{93}{10}[/tex] × [tex]\frac{5}{2}[/tex] = [tex]\frac{93}{4}[/tex] miles

To calculate Lucy's time over the same distance use

Time = [tex]\frac{distance}{speed}[/tex]

Change speed to an improper fraction

6 [tex]\frac{1}{5}[/tex] = [tex]\frac{31}{5}[/tex], hence

time = [tex]\frac{\frac{93}{4} }{\frac{31}{5} }[/tex]

       = [tex]\frac{93}{4}[/tex] × [tex]\frac{5}{31}[/tex] ( cancel 93 and 31 )

      = [tex]\frac{3(5)}{4}[/tex]

      = [tex]\frac{15}{4}[/tex] = 3.75 hours

Final answer:

It took Lucy approximately 160.17 minutes to bike the trail.

Explanation:

Jasmine finished the bike trail in 2.5 hours at an average rate of 9 3/10 miles per hour. Lucy biked the same trail at a rate of 6 1/5 miles per hour. To find out how long it took Lucy to bike the trail, we can use the formula:

Time = Distance / Rate

Since the distance is the same for both Jasmine and Lucy, we can set up an equation:

2.5 = Distance / 6 1/5

To solve this equation, we first need to convert 2.5 into a fraction. 2.5 is the same as 2 1/2. So, the equation becomes:

2 1/2 = Distance / 6 1/5

To make the equation easier to work with, we can convert 2 1/2 into an improper fraction: 2 1/2 = 5/2. The equation now becomes:

5/2 = Distance / 6 1/5

To solve for Distance, we can use cross-multiplication:

(5/2)(6 1/5) = Distance

Simplifying the right side of the equation:

(5/2)(31/5) = Distance

(5/1)(31/5) = Distance

31 = Distance

So, the distance of the bike trail is 31 miles. Now, we can find out how long it took Lucy to bike the trail by using the formula Time = Distance / Rate:

Time = 31 / 6 1/5

Once again, let's convert 31 into a fraction: 31 = 31/1. The equation now becomes:

Time = 31/1 / 6 1/5

To divide fractions, we can multiply by the reciprocal of the second fraction. So, the equation becomes:

Time = 31/1 * 5 1/6

Now, we can convert 5 1/6 into an improper fraction: 5 1/6 = 31/6. The equation now becomes:

Time = 31/1 * 31/6

To multiply fractions, we can multiply the numerators together and the denominators together. So, the equation becomes:

Time = (31*31) / (1*6)

Calculating the numerator and denominator separately:

Time = 961 / 6

So, it took Lucy approximately 160.17 minutes to bike the trail.

Using the exponential growth formula, it is determined that by the end of five generations, 4096 people will know the art of quilling, starting with one teacher teaching four students, and each subsequent student teaching four others.

The question involves an exponential growth scenario where Amanda teaches the art of quilling to four students, and then these students each teach four others, and so on for five generations. To find out how many people will know the art of quilling by the fifth generation, we use the formula for exponential growth: Total = a(1 + r)^n, where a is the initial amount (number of people who know the art at the beginning), r is the rate of increase (each person teaches 4 others means the rate is 4), and n is the number of generations.

The initial teacher, Amanda, is not counted in the first generation of students she teaches, so we begin with 4 students as our initial amount (a=4). Thus, the calculation for five generations becomes: Total = 4(4)^5. The formula simplifies to 4 * 1024 = 4096 people. Therefore, by the end of five generations, 4096 people will know the art of quilling.
