Answer:

10x + 2

Step-by-step explanation:

Step-by-step explanation:

bobby's cat runs x mph. bobby's dog runs twice as fast as his cat. if the cat and the dog start running away from each other, how far away from each other will they be after 30 minutes

Answers

Answer:

They will be 0.5x miles away from each other.

Calculation of the distance:

Since Bobby's cat runs x mph. Bobby's dog runs twice as fast as his cat.

So here the speed of the dog should be 2x

Now we know that

Here distance of cat should be x of 30 minutes or half hour = 0.5x miles

And, Distance of dog should be 2x of 0.5 = x miles

So, the difference should be

= x - 0.5

= 0.5x miles

hence, They will be 0.5x miles away from each other.

Step-by-step explanation:

Answer:

1.5x miles, because you already know that the cat's speed is 0.5x miles, and the dog is x miles, so when you add it together, you get 1.5x miles

Solve the system of equations by graphing. Check the solution. y=-2x-3. y=2x+5. Graph each equation on the same coordinate plane. At what point do the graphs of the lines appear to intersect?​

Answers

Answer:

[tex]\left \{ {{x=-2} \atop {y=1}} \right.[/tex]

Step-by-step explanation:

[tex]\left \{ {{y=-2x-3} \atop {y=2x+5}} \right.[/tex]

Substitute into one of the equations
[tex]-2x-3=2x+5[/tex]

Rearrange variables to the left side of the equation
[tex]-2x-2x=5+3[/tex]

Combine like terms
[tex]-4x=5+3[/tex]

Calculate the sum or difference
[tex]-4x=8[/tex]

Divide both sides of the equation by the coefficient of variable
[tex]x=-\frac{8}{4}[/tex]

Cross out the common factor
[tex]x=-2[/tex]

Substitute into one of the equations
[tex]y=-2\times\left(-2\right)-3[/tex]

Calculate
[tex]y=1[/tex]

The solution of the system is

Kilani and Adrian are starting a nutrition program. Kilani currently consumes 1200 calories a day and will increase that number by 100 calories each day. Adrian currently consumes 3230 calories a day and will decrease that number by 190 each day. They will continue this pattern until they are both consuming the same number of calories per day. In how many days will that be? Be sure to define your variables, write an equation, and answer the question in context.

Answers

Answer:

7 days

Step-by-step explanation:

Let us represent the number of days = a

Kilani currently consumes 1200 calories a day and will increase that number by 100 calories each day.

1200 calories + 100 calories × a

1200 + 100a

Adrian currently consumes 3230 calories a day and will decrease that number by 190 each day.

3230 calories - 190 calories × a

3230 - 190a

The number of days that they would be consuming the same number of calories =

Kilani = Adrian

1200 + 100a = 3230 - 190a

Collect like terms

190a + 100a = 3230 - 1200

290a = 2030

a = 2030/290

a = 7 days

Therefore, the would be consuming the same number of calories in 7 days

In a high school of 1000 students, 355 are playing sports and 233 are in a school band. If there are 175 students playing sports and are in a school band, how many are in neither activity?

Answers

Answer:

237

Step-by-step explanation:

1000 minus 355= 645

645 minus 233= 412

412 minus 175= 237

Answer:

237 students

Step-by-step explanation:

355 are playing sports

233 are in a school band.

175 in both

355 + 233 + 175 = 763

763 students are in sports, band or both

1000 - 763 = 237

237 students aren't participating in neither.

Need help with geometric series'!
Please include a step by step explanation.

Answers

Answer:

[tex] - 13107[/tex]

Step-by-step explanation:

We would like to evaluate the following Geometric Series ,

[tex]\displaystyle\longrightarrow \sum _{n=1}^8 (-4)^{n-1 }[/tex]

In a geometric series, a common number is multiplied to the previous term in order to find the next term . And that common number is called common ratio (r) .

As we know that ,

[tex]\displaystyle\longrightarrow \sum_{x = 1}^n f(x) = f(1) + f(2) + \dots + f(n) [/tex]

So , we can write the series as ,

[tex]\displaystyle\longrightarrow (-4)^{1-1}+(-4)^{2-1}+\dots +(-4)^{8-1} [/tex]

Simplify,

[tex]\displaystyle\longrightarrow (-4)^0 + (-4)^1+(-4)^2+\dots +(-4)^7 [/tex]

We can find the common ratio by dividing and successive term by its preceding term , as ;

[tex]\displaystyle\longrightarrow r =\dfrac{-4}{1}=-4 [/tex]

Again , here ;

First term = a = [tex](-4)^0=1[/tex]Common ratio = [tex]-4[/tex]number of terms (n) = 8

And we can find the sum of geometric series using the formula , ( this is used when the value of r is less than 1 , here it is -4 ) .

[tex]\displaystyle\longrightarrow \Bigg[ Sum = \dfrac{a(1-r^n)}{1-r}\Bigg] [/tex]

where the symbols have their usual meaning.

On substituting the respective values, we have;

[tex]\displaystyle \longrightarrow\rm{ Sum }=\dfrac{ 1\{1-(-4)^8\}}{1-(-4)}\\ [/tex]

Simplify ,

[tex]\displaystyle\longrightarrow \rm{Sum} = \dfrac{1-65536}{1+4}\\[/tex]

[tex]\displaystyle\longrightarrow \rm{Sum} = \dfrac{-65535}{5} [/tex]

Simplify by dividing ,

[tex]\displaystyle\longrightarrow \underline{\underline{ \rm{Sum} = -13107}} [/tex]

And we are done !

the distance a car travels d, is a function of t the time it travels a certain car travels 425 miles at a speed of 50 miles per hour. What are the domain range of the function described?

Answers

The domain and range of the linear function described are given as follows:

The domain is all real values from 0 to 8.5 and the range is all real values from 0 to 425.

What is a linear function?

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.

In this problem, the car travels 425 miles at a speed of 50 miles per hour, hence for the amount of miles left for the car to travel after t hours is given by a linear function with m = -50 and b = 425, that is:

d(t) = 425 - 50t.

The domain is the set of all possible values of the input, which considering that the car travels while the distance is greater than 0, is given by:

d(t) > 0 -> 425 - 50t > 0 -> t < 8.5.

The range is the set of all possible values of the input, which is the distance remaining, assuming real values from 0 to 425.

Hence, the correct option is:

The domain is all real values from 0 to 8.5 and the range is all real values from 0 to 425.

Find the range of the data. 133,117,152,127,168,000,000

Answers

Answer:

168

Step-by-step explanation:

168  would be the range because the range is the highest number - the lowest number so 168=highest and 000=lowest

so 168-000 or just0=168

here's some extra answers.


The mean=100 rounded up to nearest 100

Mean= the average of the data set.

Median=127

The median is the middle number when the numbers in the data set are sorted least to greatest.

Mode=000 or just 0

The mode is the number that appear the most in the data set and 000 or just 0 appears twice rather than,all the other numbers only appear once.

Minimum=000 or just

The minimum is the lowest number in the data set and as for this one is is 0.

Maximum=168

The maximum is the highest number and the data set and 168 is the highest in this one.
