Answer:

I think x=46 but I'm not sure, hope this helps

Answer:

x + 2x = 30 is the correct answer.

Answer:

See explanations below

Step-by-step explanation:

In the function

f(x) = x + 30

x represents the volume of coal in cubic yards.

The implicit coefficient of one, i.e. 1x, represents each cubic yard of coal weighs one ton.

The 30 represents the weight in tons of the empty coal car.

Thus when the weight of the coal car is only 26 tons, we replace 30 by 26 to get a new function

f(x) = x + 26.

Answer:

1200

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.

I want to make this clear, this is NOT MY ANSWER! Someone else has already answered this question on here I'm just pasting their answer here so you can get the full details on how it was solved.

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:

5.9 hours, 10£

Step-by-step explanation:

For the first question, you must find how long it would take 1 knitter to do all the work, and you can move on from there. Since it takes 11 knitters 7 hours, it would take 1 knitter 11 times as long, meaning it would take 7*11=77 hours for 1 knitter. Now we can divide 77 hours by 13 as 13 knitters could to it in 1/13 of the time. Dividing 77 by 13 we get 5.9 hours.

For the second question, if each person pays 9£, and there are 10 people, in total they are paying 10*9£=90£. This means that if the spit it up between 9 people instead, each would by 90£/9=10£. This means they would each have to pay 10£.

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:

No, it does not.

Step-by-step explanation:

Immediately from the given equation, we can see that it has a constant (-5).

Direct variation equations are in the form y=kx, where k is an coefficient. There are no constants in direct variations.

Answer:

There are about 568 miles left of the trip

Step-by-step explanation:

Notice that the 830 miles direct trip would be the hypotenuse of a right angle triangle. The captain goes due North for 605 mi, and then needs to turn west.

Please see the attache image to guide you.

So the question is what is the length of the third side (x) of that right angle triangle which accounts for the distance that has to be sailed due west. So we use the Pythagorean theorem:

[tex]hyp^2=leg_1^2+leg_2^2\\830^2=605^2+x^2\\x^2=830^2-605^2\\x=\sqrt{830^2-605^2} \\x=568.22\,\,mi[/tex]

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.

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:

0.5686

Step-by-step explanation:

The alternative hypothesis would be p ≠ 0.11. Thus, this is a two tailed test.

We are given;

p = 0.11

p^ = 8/88 = 1/11 = 0.0909

n = 88

Formula for the Test Statistic is given by;

z = (p^ - p)/(√(p(1-p)/n))

z = (0.0909 - 0.11)/(√(0.11(1 - 0.11)/88))

z = - 0.572642

z ≈ -0.57

Now, from the z-table to find the P-value at z = -0.57 is; 0.2843

Since this is a two tailed test, we have to multiply the P-value by 2 to get the total P-value.

Thus, P-value = 2 × 0.2843 = 0.5686

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:

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...
