Answers

Answer 1

The first step is to move -x to RHS and second step is to solve to get the value of x. The solutions will be x = -2 , 0 , 2.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , division , etc.

The equation given is [tex]4x^{1/3}[/tex]- x = 0

We need to solve it stepwise.

The first step will be to to move -x to RHS.

[tex]4x^{1/3}[/tex]- x = 0

or

[tex]4x^{1/3}[/tex] = x

The second step is to solve to get the values of x.

4x = x³

4x - x³ = 0

x (4 - x²) = 0

So , this will give us two equations which are ,

x = 0

and

4 - x² = 0

or

x² = 4

x = ± 2

So , solving the equation for x initially yields two equations which are x = 0 and 4 - x² = 0 and the solution we get is x = 0 , 2 , - 2.

Thus , the solutions will be x = -2, 0, 2.

What is equivalent?

A comparable is how much a substance that responds with an erratic measure of one more substance in a given synthetic response. Comparable weight can be characterized as the mass of one likeness a given substance that will consolidate with or uproot a decent amount of the other substance. Identical loads not entirely set in stone by try, however (to the extent that they are as yet utilized) are currently gotten from molar masses. Identical load in science is the most widely recognized term utilized and one of the fundamental ideas of science in the actual science part. The significance of 'identical' by and large alludes to two numbers, articulations, or amounts with a similar worth. There are numerous ways of communicating a comparable amount - it tends to be indicated either by a bar or an identical image.

Root 40 to the nearest 10

Answers

Root 40 to the nearest 10 is 6.3

The root of a number in math is a number that when multiplied by itself produces the original number. For example, the square root of 49 is 7 because 7×7=49.

Rounding off to the nearest 10 means that we wish to round off the last two digits of a number, that is up to the tens place of a number.

We have been given that 40 is the number whose root we have to round off so here are step-by-step instructions for how to get the square root of 40 to the nearest tenth:

Step 1: Calculate. We calculate the square root of 40 to be: √40 = 6.32455532033676.

Step 2: Reduce. 6.32.

Step 3: Round. Round 6.32 so you only have one digit after the decimal point to get the answer: 6.3.

So therefore the nearest 10 of root 40 is 6.3

answer as an equation and solve, please help!!

Answers

The equation which represents the given situation as described about snow depths in the task content is; 4 + 3x = 1 + 5x and the solution is; x = 1 and a half hours.

At what time will the snow fall of the towns in discuss have the same snow depth according to the given rates?

It follows from the task content that the time at which the snowfall in the towns in discuss will be equal be determined.

According to.the word phrases given;

A town has accumulated 4 inches of snow and the snow depth is increasing by 3 inches every hour. Hence, we have;

4 + 3x.

Also, a nearby town has accumulated 1 inch and the depth is increasing by 5 inches every hour. Hence ,we have;

1 + 5x

Consequently, when the snowfalls are equal, we have;

4 + 3x = 1 + 5x

3 = 2x

x = 3/2.

x = 1 and a half hours.

Ultimately, the equation which represents the given situation as described about snow depths in the task content is; 4 + 3x = 1 + 5x and the solution is; x = 1 and a half hours.

X in an example​ of stochastic variable.

What is meant by stochastic variables?

Typically, a random (or stochastic) variable is defined as a variable that can assume more than one value due to chance.

The correct answers are: (a) stochastic variable: By stochastic variable we mean a variable (here X: the weight of students) whose values are subject to variation due to chance.

Here since X is the weight of the children sampled, hence X will vary along with change in the sampling units which gets selected by chance.

Hence X for a sample A and X value for a different sample B will be different. So the values of X vary due to chance ( chance takes part in the selecton of the sample). So X is a stochastic variable.

a​ company's charge for electricity is ​¢6.434 per​ kilowatt-hour. in​ addition, each monthly bill contains a customer charge of ​$7.81. if last​ year's bills ranged from a low of ​$51.74 to a high of ​$​192.28, over what range did usage vary​ (in kilowatt-hours)? course hero

Answers

The range in which the usage vary is from 682.77  kilowatt-hours to 2867.11  kilowatt-hours.

Given the charge of electricity charge is 6.434 cents  per​ kilowatt-hour.

Fixed customer charge = ​$7.81

Bill range = $51.74 to ​$​192.28

Since every value is in $ , we will first convert cents to dollar

per​ kilowatt-hour charge will be $6.434/100    ( as $1 = 100 cents )

per​ kilowatt-hour charge = $ 0.06434    …(1)

Lets us first find the lower range of usage

Last year's lowest bill was $51.74 (including the customer charge)

So last year lowest bill = $51.74-$7.81  = $43.93   …(2)

We know that (per KWh charge)x(no. of KWh used)=Total bill. …(3)

Substituting the values from (1) & (2) we get

(0.06434)x(no. of KWh used)=$43.93

no. of KWh used=[tex]\frac{43.93}{0.06434} = 682.77 KWh[/tex]

Similarly we will solve for maximum KWh used

Lets us find the maximum range of usage

Last year's highest bill was $192.28 (including the customer charge)

So last year highest bill = $192.28-$7.81  = $184.47   …(4)

Substituting the value of (1) & (4) in (3) we get

(0.06434)x(no. of KWh used)=$184.47

no. of KWh used=[tex]\frac{184.47}{0.06434} =2867.11 KWh[/tex]

Therefore ,  the The range in which the usage vary is from 682.77 kilowatt-hours to 2867.11  kilowatt-hours.

Mason is going to an amusement park. The prize of the admission into the park is $30, and once he is inside the park, he will have to pay $2 for every ride he rides on. How much money would mason have to pay in total if he goes on 9 rides? How much would he have to pay if he goes on r rides

Answers

Answer: $48 for 9 rides

$(30+2r) for r rides

Step-by-step explanation:

r=rides. t=total money spent

t=30+2r

t=30+2(9)

t=30+18

t=$48 for 9 rides

t=$(30+2r) for r rides

Mason has to pay $48 as total if he goes on 9 rides and he would have to pay a total of $30 + $2r if goes on r rides.

If Mason goes on 9 rides, we can calculate his total cost using the given information.

Admission cost: $30

Cost per ride: $2

Number of rides: 9

Total cost = Admission cost + (Number of rides × Cost per ride)

Total cost = $30 + (9 × $2)

Total cost = $30 + $18

Total cost = $48

Now, let's calculate how much he would have to pay if he goes on "r" rides.

Total cost = Admission cost + (Number of rides × Cost per ride)

Total cost = $30 + (r × $2)

Total cost = $30 + $2r

So, if Mason goes on 9 rides, he would have to pay a total of $48 and  if Mason goes on "r" rides, he would have to pay a total of $30 + $2r.
