Answer:

x + 2x = 30 is the correct answer.

Answer:

No.

Step-by-step explanation:

To determine if the ordered pair is a solution, simply plug it into the equation and check. In other words:

[tex]y\geq x^2-4[/tex]

[tex]0\geq (0)^2-4[/tex]

[tex]0\geq -4[/tex]

This is true. 0 is greater than -4.

[tex]y<2x-1[/tex]

[tex]0<2(0)-1[/tex]

[tex]0<-1[/tex]

This is not true. 0 is greater than -1.

Thus, (0,0) is not a solution.

Answer:

(0,0) is not a solution of the given system.

Step-by-step explanation:

0≥-4 true

0>1 false

(0,0) is not a solution of the system.

13x ≤ 39

13x ≤ 39 ÷13

x ≤ 3

Answer:

One.

Step-by-step explanation:

It is a linear equation. This means that x is raised to the first power, which there can only be one solution.

Answer:

Hi, the correct answer to your question is Y,X would be (29,11)

ONE SOLUTION

Step-by-step explanation:

First you have to... solve for y

Y equals 2x+7

Next you have to use the variable y and put in into an equation.

2x+7 - 3x = -4 (Also) :) - x = -11

Now you have to solve the equation for the variable x

Which will be 11 (x will be 11)

Finally you have to use x to solve for y

2(11)+7 = 29

Now we have 11 and 29 so the answer to your question will be

= (29,11)

Also this means it has one solution

Btw this is a linear equation...

Hope this helps you! :)

Answer:

$186.75

Step-by-step explanation:

In order to solve this, we first need to convert the percentage into a decimal which can be done by dividing it by 100 like so

24.5 % 100 = 0.245

Now that we have the decimal form of the percentage we add a 1 to it and multiply that by $150 in order to get the total amount that is owed after two weeks .... without the 1 added it would only give us the amount of interest that needs to be paid.

$150 * 1.245 = $186.75

Therefore after two weeks you would need to pay a total of $186.75

Answer:

Records: $6000

Grass Seed: $4000

Toys: $3000

Food: $11000

Step-by-step explanation:

We have to use the number of degrees in each category in comparison to the total number of degrees in a circle, 360 degrees. Records is 90 degrees, so 90:360 = 1:4 = 1/4. So 1/4 of the total pie is $6000. For food, we add the other sub-category's costs, and subtract that from $24000.

Answer:

Step-by-step explanation:

1. Toys = [tex] \frac{45}{360} \times 24000 = 3000[/tex]

2. Grass seed[tex] = \frac{60}{360 } \times 24000 = 4000[/tex]

3. Records = [tex] \frac{90}{360} \times 24000 = 6000[/tex]

4. Food = 24000 - ( 3000+4000+6000)

= 24000 - 13000

= 11000

Answer:

Kristen had (3/4) of a granola bar in total.

Then the three other people have 2.25 granola bars to share amongst themselves.

Step-by-step explanation:

Complete Question

Tom, Kristen, Kaley, and Bill bought 3 granola bars to share among themselves. They divided each granola bar into 4 equal portions. Kristen ate 1 portion from each granola bar.

How many granola bars did Kristen eat.

Solution

4 of them bought 3 granola bars.

Then they divide each granola bar into 4 equal portions.

Each of the 3 granola bars gets divided into 4 equal portions, where each granola bar now has (4 × 1/4) portions.

Each portion is (1/4) of a granola bar.

Kristen then takes 1 portion from the 3 granola bars.

This means she had 3 × (1/4) granola bars.

Kristen had (3/4) of a granola bar in total.

Then the other three people had [3 - (3/4)] of a granola bar to share amongst themselves. It means they had (9/4) or 2.25 granola bars to share amongst themselves.

Answer:

245.04 cm²

Step-by-step explanation:

Use the formula for the surface area of a cylinder: 2[tex]\pi[/tex]r² + 2[tex]\pi[/tex]rh

Now, we can plug in the values:

2[tex]\pi[/tex](3)² + 2[tex]\pi[/tex](3)(10)

18[tex]\pi[/tex] + 60[tex]\pi[/tex] = 245.04

The total surface area of the can is 244.92 square centimeters which is closest to 245.04 square centimeters.

We have a can in the shape of a cylinder has a diameter of 6 centimeters and a height of 10 centimeters.

We have to determine total surface area of the can in square centimeters.

The total surface area of a cylinder with radius 'r' and height 'h' is given by -

A = 2πr(h + r)

According to the question, we have -

diameter of can = 6 cm

Then, the radius will be (r) = 6/2 = 3 cm

Height of can (h) = 10 cm

Substituting the values, we get -

A = 2 x 3.14 x 3 (10 + 3)

A = 2 x 3.14 x 3 x 13

A = 6 x 13 x 3.14

A = 78 x 3.14

A = 244.92 square centimeters.

Hence, the total surface area of the can is 244.92 square centimeters which is closest to 245.04 square centimeters.

Answer:  105, 15, 35, 21

Step-by-step explanation:

3 x 5 x 7 = 105

3 x 5       = 15

     5 x 7 = 35

3    x    7 = 21

The list of all composite factors of K are 15, 21, 35, 105.

A number which can be divisible by only 1 and the number itself, that number is said to be a Prime Number.

A number which can be divisible by factors other than 1 and itself are called Composite Numbers.

The process to write a number by the product of its prime numbers is called Prime Factorization.

Here given that the prime factorization of K is given by,

[tex]K=3\times5\times7[/tex]

Hence the number is [tex]K=105[/tex].

Composite factors of a number are given by the product of prime factors of that number in different combinations.

Here prime factors are 3,5,7

The composite factors are given by,

[tex]3\times5=15\\5\times7=35\\3\times7=21\\3\times5\times7=105[/tex]

Thus the composite factors of K are given by 15,21,35,105.

Answer: independent variables cause the effect measured in the dependent variables

Step-by-step explanation: In a causal - comparative study, the dependent variables refers to the variable whose changes is being measured or observed. The changes or alteration of the dependent variable is induced by the different values of the independent variable. In causal - comparative study, the different independent variables is assumed to have a direct impact on the output or values of the dependent variable which is measured by the experimenter. Therefore, the independent variable does not change, but causes the observed changes noticed in the dependent variable.

We know that 1/5 > 1/6 > 1/7

If we change the numbers to decimals we can see what decimals we can use that are between the number 1/5 and 1/7 .

1/5=.20

1/7≈.14

We can use any number between these two decimals to create a fraction. Let us use .16

.20>.16>.14

Now we can change that number to a fraction.

.16=16/100 which reduced to 4/25

Let's verify:

1/5 > 4/25 > 1/7    find LCM

35/175 > 28/175 > 25/175

One fraction that is between 1/5 and 1/7 that does not have a denominator of 6 is 4/25.

Answer:

Hypotenuse: 100

Segment Adjacent to the leg: 36

x=60

Step-by-step explanation:

I submitted and it was correct

The altitude of the triangle is approximately 76.81 units.

To find the altitude of the triangle, we can use the given information:

Hypotenuse: 100

Segment adjacent to the leg: 36

Let's denote the altitude as 'h' and the other leg of the right triangle as 'x'.

Using the Pythagorean theorem, we can relate the three sides of the triangle:

[tex]h^2 + x^2 = 100^2[/tex]

We also know that the adjacent segment (36) plus the other leg (x) equals the hypotenuse (100):

36 + x = 100

From the second equation, we can solve for x:

x = 100 - 36

x = 64

Now, substitute the value of x into the Pythagorean theorem equation to solve for h:

[tex]h^2 + 64^2 = 100^2\\\\h^2 + 4096 = 10000\\\\h^2 = 10000 - 4096\\\\h^2 = 5904[/tex]

Taking the square root of both sides to solve for h:

h = √5904

h ≈ 76.81

Therefore, the altitude of the triangle is approximately 76.81.

Answer:

Step-by-step explanation:

Answer:

114,400 and 118,976.

Step-by-step explanation:

Let's represent this using a function. Let's let:

[tex]P(y)[/tex] represent the total population, and [tex]y[/tex] represent the total number of years since last year.

We know that the population grows by 4% every year or 0.04 every year. This is exponential growth. We can write this as:

[tex]P(y)=110000(1.04)^y[/tex]

Note that the coefficient is 110000 because that is the year we are starting with. Also, note that it is 1.04 because we are essentially adding .04 to the original population.

Anyways, to find the present population, set y equal to 1 (because 1 year after last year is the present year)

[tex]P(1)=110000(1.04)^1=114400[/tex]

The present population is 114,400 people.

For next year, set y equal to 2 (2 years after last year is next year)>

[tex]P(2)=110000(1.04)^2=118976[/tex]

The population next year will be 118,976 people.
