Answer:

3. No errors were made. The problem was worked correctly.

Step-by-step explanation:

2(10x + 3) − x = 44

Distribute

20x +6 -x =44

Combine like terms

19x +6 = 44

Subtract 6 from each side

19x =38

Divide by 19

19x/19 =38/19

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.

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:

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: 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.

Answer:

El libro que Renzo está leyendo tiene 300 páginas.

Step-by-step explanation:

Dado que Renzo ha leído el 20 por ciento del libro de cuentos, en principio le queda leer el 80 por ciento de éste. Ahora bien, de las páginas restantes (es decir, de ese 80 por ciento) ha leído 1/4 parte. Por ende, ha leído un 20 por ciento adicional de dicho libro (80 /4 x 1 = 20). En conclusión, Renzo lleva leído un 40 por ciento del libro, con lo cual le resta leer un 60 por ciento, que está formado por 180 páginas. Para determinar cuántas páginas tiene el libro, entonces, hay que realizar el siguiente cálculo:

180 / 60 = 3 (valor del 1 por ciento del libro)

3 x 100 = 300 (valor del 100 por ciento del libro)

Por lo tanto, el libro que Renzo está leyendo posee 300 páginas.

Answer:

0.46 each

Step-by-step explanation:

Answer:

£0.46 per pen

Step-by-step explanation:

We need to find the unit rate, or price per pen.

Therefore, we can divide the price by the number of pens.

price / number of pens

It costs £2.76 for 6 pens.

price= £2.76

number of pens = 6 pens

£2.76 / 6 pens

Divide 2.76 by 6

£0.46 / pen

The price per pen is  £ 0.46

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:

A. Jorge distributed incorrectly.

Step-by-step explanation:

4x - (x + 20) + 6 = 2(3x + 8)

4x - x - 20 + 6 = 6x + 16

3x - 14 = 6x + 16

3x - 6x = 16 + 14

-3x = 30

x = -10

For Step 1 of Jorge's work, he writes "4x - x + 2 + 6 = 6x + 16", instead of "4x - x - 20 + 6 = 6x + 16". That is the error that messes up the rest of his calculations.

What he did wrong does not apply to addition, subtraction, multiplication, or division, so we can eliminate choices C and D. Jorge isn't combining like terms, either, so we can eliminate choice B. What Jorge did wrong was that he distributed incorrectly, so that is your answer: A. Jorge distributed incorrectly.

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: It would take 40 minutes to mow a lawn with a mower containing 12-inch wide blades.

Step-by-step explanation:

If the time taken by 14 inches wide is one hour then the blade of 12 inches wide will take 1 hour 17 minutes to mow a lawn.

The width of something is the measurement of one side of a body. It is generally less than length of that body or shape.

We have been given time of 1 hour if blade is 14 inches wide and we have to calculate time taken by 12 inches wide blade:

It will be as 14/12* 1 hour

=14/12

=1.167

=1.17 hour

Hence the time taken by the blade of 12 inches wide will be 1 hour and 17 minutes.

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.

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)
