A balloon holds 5.2 cubic feet of air. The balloon is blown up larger to hold 8.3 cubic feet of air. What is the percent
of change for the volume of air inside the balloon?

Answer:

5.1, 5 1/10

Step-by-step explanation:

(3.5 − 2/3) ⋅ (−2.8 + 4 3/5) =

= (7/2 - 2/3)(-14/5 + 23/5)

= (21/6 - 4/6)(9/5)

= (17/6)(9/5)

= (17 × 9)/(6 × 5)

= 51/10

= 5.1 = 5 1/10

Answer:

y = 2w - 1 + aw

Step-by-step explanation:

Given

y - aw = 2w - 1 ( isolate y by adding aw to both sides )

y = aw - 1 + aw

 In one design being considered for the containers shaped like a rectangular O.D. of 15 inches,Therefore, l = w.

the volume of the container is 0.0076 m³. Let us determine the height of the container using the given information.

The volume of the container can be expressed using the formula V = lwh where V is the volume, l is the length,

w is the width and h is the height.Substituting the given values into the formula,

we have;V = lwh0.0076 = (15 × w) × h... equation [1]

Since the container is shaped like a rectangular O.D,

the length and width are equal.

Substituting l = w into equation [1]

0.0076 = (15 × l) × h0.0076 = 15l × h... equation [2]

From equation [2],

h can be expressed as:

h = 0.0076/(15l)

Hence, the height of the container is given by h = 0.0076/(15l).

Step-by-step explanation:

the fraction of four-digit positive integers containing only digits from the set {2,4,6,8} that have at least one of their digits repeated is 29/32.

First, let's determine the total number of four-digit positive integers using digits from the set {2,4,6,8}. Since there are 4 choices for each of the 4 digits, there are a total of 4^4 = 256 possible integers.

Next, we'll count the number of four-digit integers without any repeating digits. Since there are 4 choices for the first digit, 3 choices for the second digit, 2 choices for the third digit, and 1 choice for the last digit, there are a total of 4! (4 factorial) = 4 x 3 x 2 x 1 = 24 integers without any repeating digits.

Now, to find the number of integers with at least one repeating digit, we can subtract the number of integers without any repeating digits from the total number of integers: 256 - 24 = 232 integers.

Finally, to find the fraction of these integers with at least one repeating digit, we'll divide the number of integers with at least one repeating digit by the total number of integers: 232/256 = 29/32.

For the given geometric sequence we have:

a) R = 3/4

b) 243/256

c) Aₙ = 3*(3/4)⁽ⁿ⁻¹⁾

The common reason is given by the quotient between two consecutive terms, so using the first two, we will get:

R = (9/4)/3

R = 3/4

That is the common reason.

b) To find the fifth therm, we need to take the fourth one and multiply it by the common reason, so we will get:

Answer:

Step-by-step explanation:

The answer for the missing piece is to 'find' the variable.

The coefficient of (3y² + 9)5 is 15.

A polynomial is of the form a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² + ... + aₙ₋₁x + aₙ.

Here, x is the variable, aₙ is the constant term, and a₀, a₁, a₂, ..., and aₙ₋₁, are the coefficients.

a₀ is the leading coefficient.

In the question, we are asked to identify the coefficient of (3y² + 9)5.

First, we expand the given expression:

(3y² + 9)5

= 15y² + 45.

Comparing this to the standard form of a polynomial, a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² + ... + aₙ₋₁x + aₙ, we can say that y is the variable, 15 is the coefficient, and 45 is the constant term.

Thus, the coefficient of (3y² + 9)5 is 15.

One gallon equals 16 eight ounce glasses of water.

According to the EPA, conventional shower heads utilize 2.5 gallons of water each minute. For the normal shower, that’s 20 gallons of water! To help lower your water impact, try trimming three minutes off your shower time. Delivering, purifying, and boiling hot water for your shower also consumes a lot of energy.

To determine the average shower water use, multiply the average flow rate of 2.1 gallons per minute by the average shower time of 8.2 minutes. So, 17.2 gallons is the average amount of water utilized. A 10-minute shower will consume 21 gallons of water. The amount of water consumed in the shower may quickly add up.

What is Similarity of Triangles?

Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion.

Solution:

Side-Side-Side (SSS) - If equivalent sides in two triangles have the same ratio, then their corresponding angles are equal, and the triangles are identical (SSS similarity criterion).

Angle-Angle-Angle (AAA) - If all the three angles of one triangle are equal to the three angles of the other triangle in two triangles, then the two triangles are comparable (AAA similarity criterion).

Side-Angle-Side (SAS) - If one angle of one triangle equals one angle of another triangle, and the sides containing these angles have the same ratio (proportional), the triangles are comparable (SAS similarity criterion).

Angle-Side-Angle (ASA) - By ASA rule, two triangles are said to be similar if any two angles and the side included between the angles of one triangle are proportional to the corresponding two angles and side included between the angles of the second triangle.

The percentage of category shelf facings for Brand F is 10% out of the total facings allotted for all brands in that category, based on the information provided.

To calculate the percentage of category shelf facings for Brand F, we need to determine the proportion of shelf facings allotted to Brand F out of the total facings allotted for all brands in that category.
Company U has 100 outlets, and half of those outlets carry Brand F. This means that there are 50 outlets that carry Brand F.
Out of the 50 facings allotted for all brands in that category, Company U allots Brand F 5 shelf facings.
To find the percentage, we divide the facings allotted to Brand F (5) by the total facings allotted for all brands in the category (50), and then multiply by 100 to express it as a percentage.
(5 facings / 50 facings) * 100 = 10%
Therefore, the percentage of category shelf facings for Brand F is 10%. This indicates that Brand F occupies 10% of the available shelf space in the category across Company U's outlets.

Answer:

x = 15, ∠ B = 108°

Step-by-step explanation:

∠ A and ∠ B are alternate exterior angles and congruent, so

6x + 18 = x + 93 ( subtract x from both sides )

5x + 18 = 93 ( subtract 18 from both sides )

5x = 75 ( divide both sides by 5 )

x = 15

Then

∠ B = x + 93 = 15 + 103 = 108°

Sampling Error is defined as; the discrepancy between a sample estimate of a population parameter and the real population parameter.

A sampling error is defined as a deviation that occurs in the sampled value when compared to the true population value. Now, sampling errors usually occur due to the fact that the sample is not representative of the population or is biased in some way.

The sampling error formula is used to estimate the overall sampling error in any given statistical analysis. The way we calculate the sampling error is by dividing the standard deviation of the population by the square root of the size of the sample, and thereafter multiplying the result with the Z-score value, which is largely based on the confidence interval.

Looking at the options, from the definitions above, it is clear that the sampling error is defined by option C
