The volume of a cube is 125 cubic inches what is the length of 1 edge of the cube

Answer: 4r-8+4y

Step-by-step explanation: Distribution is when you multiply every term inside the parantheses by the outside term. So 4(r-2+y)=4(r)+4(-2)+4(y). This is the same as 4r-8+4y. Since none of these are like terms we have the fewest symbols possible.

Answer:3 5/7

Answer:   A ----------------3 5/7

Answer:

Let's call the number of Twix bars "x".

Since there are three times as many Twix bars as Milky Ways, the number of Milky Ways is x / 3.

And, since there are 5 fewer Snickers bars than there are Twix bars, the number of Snickers bars is x - 5.

So, the total number of candy bars can be found by adding the number of each type of candy bar:

x + x / 3 + x - 5 = total number of candy bars

Combining like terms, we get:

5x / 3 - 5 = total number of candy bars

To find the value of x, we can solve this equation for x.

5x / 3 = total number of candy bars + 5

5x / 3 = total number of candy bars + 5

5x = 3(total number of candy bars + 5)

5x = 3(total number of candy bars) + 15

5x = 3(total number of candy bars) + 15

5x - 15 = 3(total number of candy bars)

5x - 15 = 3(total number of candy bars)

(5x - 15) / 3 = total number of candy bars

So, the total number of candy bars can be found by dividing (5x - 15) by 3. The value of x represents the number of Twix bars, and the rest of the candy bars can be found using the relationships described in the problem.

The 8th term of the geometric sequence is 13122x^22

The explicit form of a geometric sequence is expressed according to the equation;

Tn = ar^n-1

where

r is the common ratio

a is the first term

n is the number of terms

Given the sequence below;

6x,18x^4,54x^7

r = 18x^4/6x

r = 3x^3

a = 6x

n = 8

Substitute to have:

T8 = 6x(3x^3)^8-1

The remainder when polynomial function is divide by linear function is 773.

Given that the polynomial functon f(x)=3x⁴+5 and the linear function is x+4.

As it is given that we have to find the remainder the polynomial

f(x)=3x⁴+5 is divided by the linear expression g(x)=x+4.

f(x)=3x⁴+5    .......(1)

g(x)=x+4       .......(2)

We know the remainder theorem that when a polynomial f(x) is divided by a linear expression (x−a), the remainder will be f(a).

From equation (2), we have a linear expression.

Now, on simplifying equation (2) to obtain the zero of g(x), we get

g(x)=x+4=0

x+4=0

Now, on comparing (x+4) and (x−a), we get

a=-4      ......(3)

Here, we have to get the value of f(a).

Now, using the remainder theorem, we can say that to get the remainder when the polynomial f(x)=3x⁴+5 is divided by g(x)=x+4, we have to replace x by -4 in the polynomial f(x)=3x⁴+5, we get

f(-4)=3(-4)⁴+5

f(-4)=3(256)+5

f(-4)=768+5

f(-4)=773

Therefore, the remainder when the polynomial f(x)=3x⁴+5 is divided by the linear expression g(x)=x+4 is 773.

when multiplicity is removed, you get 2^(2n+1)/2 members, which is 2^(2n).

Take the power set. It has 2^(2n+1) members.

Replace any member which has n+1 or more elements with its complements.

Now the power set has members, which have n or fewer elements, and each such member appears twice.

Therefore, when multiplicity is removed, you get 2^(2n+1)/2 members, which is 2^(2n).

Considering the definition of an equation and the way to solve it, the number of points Carlos scored in the last game is 19.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being:

and knowing that in the last game, Fabio had 7 points less than 2 times as many points as Carlos, the equation to determine the number of points Carlos scored in the last game is:

2C - 7= F

Fabio scored 31 points in the game. So you get:

2C - 7= 31

Solving:

2C= 31 + 7

2C= 38

C= 38 ÷ 2

C=19

The equation which can be used to determine the number of pounds of peaches and crumbles that Stephen could have purchased is 1.8x+2.5y=19.4 and if Stephen purchased 8 pounds of peaches then he also purchased 2 pounds of crumbles.

Given that the cost of peaches is $1.80 per pound and cost of crumbles is $2.50 per pound and the total expenditure done by Stephen is $19.40.

We are required to find the equation that can be used to determine the number of pounds of peaches and crumbles that Stephen could have purchased and find the number of crumbles that Stephen purchased if he had 8 pounds of peaches.

Suppose the number of pounds of peaches be x and the number of crumbles be y.

The equation will be as under:

x*1.80+y*2.50=19.40

1.80x+2.50y=19.40---------1

Put the value of x=8 to find the number of crumbles.

1.8 *8+2.50y=19.40

14.4+2.50y=19.40

2.50y=19.4-14.4

2.50y=5

y=5/2.5

y=50/25

The 65-th percentile is  approximately 83.8 ounces.

A number at or below which a particular percentage falls in its frequency distribution, or a score below which a given percentage falls, is known as the k-th percentile in statistics. The 50th percentile, for instance, is the score at or below which 50% of the distribution's scores can be found.

The percentile can be calculated by using the formula

Percentile Value = μ + zσ  where

z is the z-score , μ is the mean and σ is the standard deviation.

Here the percentile that is to be calculated is 65.

So we take the value that is closest to 0.65 from the z-table.

We get the value of the data to be 0.39

Now putting the values in the equation we get:

Percentile Value = μ + zσ  

or, Percentile Value = 83 + (0.39 × 2)

or, Percentile Value = 83.78

or, Percentile Value ≈ 83.8

Hence the 65th percentile value of the function is given by 83.8  .

200x - 75x + 57,900  

The population of the second town after x months is  given by

The linear equation for the remaining Federal Helium Reserves, r(t) = 20 -1.9t

There is 20 billion cubic feet of Helium in 2010. Helium is depleted by about 1.9 billion cubic feet each year.

Let 'r' denotes the remaining Federal Helium Reserves in billions of cubic feet.

Let 't' denotes the number of years since 2010.

We have to find a linear equation to represent the depletion of Helium through years since 2010. A linear equation will have two variables, one dependent and one independent variable. Here, let 'r' be the dependent variable and 't' be the independent variable.

Then the amount of Helium depleted in 't' years = 1.9t

So, the remaining Helium in the Federal Helium Reserve since 2010 = 20 - 1.9t.

Thus, r(t) = 20 - 1.9t

This is a linear equation because it depends on only one variable, 't'.
