is 28/7 a integer? yes or no

Hi! I'm happy to help!

Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)

2,000×4

8,000

8,000/5

Fractions are just a different way of putting division, so we can change this to a division problem:

8,000÷5=

1,600

1,600 of the people are middle class.

I hope this was helpful, keep learning! :D

I don't really know how to explain step-by-step from my messy notes

The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.

The given percentage are,

8%, 15%, and 20%.

Now to find the overall average increase we need to find the average percentage for three consecutive years.

overall average = sum of all the percentage/number of percentage

overall average =  8%+15%+ 20%/3

overall average =  43%/3

overall average =  14.33%

Hence,The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

Answer:

the answer is 8 oz

Step-by-step explanation:

well it says for the first ounce is $0.49 so $0.49 is your first number, then you're trying to figure out how many $.21

2.then to make this easier you subtract $0.49 from $1.96 and that's is $1.47

3.then all you need to do is divide $1.47 By .21 cents anand you should get 7.

4.but don't forget the $0.49 for the first ounce, then 1 ounce add it to the 7 and It will equal 8 oz in total

Explanation:

For now, let's ignore the blue curve.

If we kept the red curve completely fixed in place, and only moved the xy axis, then we can move the xy axis 5 units to the right to give the illusion the red curve is moving (even though it's fixed in place).

Moving the xy axis 5 units to the right means each x input is 5 units larger. So x jumps up to x+5

In other words, going from f(x) to f(x+5) will shift the f(x) curve 5 units to the left. So that's why we go from x^2 to (x+5)^2 which is what choice D shows.

Step-by-step explanation:

Have a nice day! :-)

Se debe remover aproximadamente 140.848 centímetros cúbicos de madera para reducir las esferas a anillos con altura de 6 centímetros.

En esta cuestión se precisa calcular el volumen de la esfera y sustraer los volúmenes de dos casquetes esféricos de igual cantidad [1] y un cilindro recto respectivo a la operación de taladrado. [2] La cantidad de madera a remover queda definida por la siguiente expresión:

[tex]V = \frac{2\pi}{3}\cdot h^{2}\cdot (3\cdot R - h) + \pi\cdot r^{2}\cdot (2\cdot R-2\cdot h)[/tex] (1)

Donde:

Si sabemos que [tex]h = 1\,cm[/tex], [tex]R = 4\,cm[/tex] y [tex]r = 2.5\,cm[/tex], entonces la cantidad de madera a remover es:

[tex]V = \frac{2\pi}{3}\cdot (1\,cm)^{2}\cdot [3\cdot (4 \,cm) - 1\,cm] +\pi\cdot (2.5\,cm)^{2}\cdot [2\cdot (4\,cm)-2\cdot (1\,cm)][/tex]

[tex]V \approx 140.848\,cm^{3}[/tex]

Step-by-step explanation:

it's irrational cuz it's negative

Answer:

Step-by-step explanation:

It seems like there is only one question. I'll answer that first and then we'll discuss what might be inferred from the introduction.

1)

The way the problem is set up you get a factoring to take place

(x^3 - 8) = (x - 2)(x^2 + 2x + 4)

                 ================      

                   (x - 2)

This question is unique. They expect you to cancel, which leaves you with y = x^2 + 2x + 4) which is a quadratic.

The reason you don't put in x = 2 is because technically, you get 0/0 which can be shown to be either 1 or 0. To get out of that, we say that 0/0 is undefined. The graphing program has taken the stance that 0/0 is 1. However I wouldn't really accept that. The whole problem comes down to 0/0 which is undefined.

Answer:

This given triangle is an equilateral triangle.

Answer:

using phythagoras formula of right angles we can calculate the hypotenuse

1^2=x^2+17^2

x^2=17^2-1^2(transpose)

×^2=288 (introduce a square root)

x=15.01(round of to the nearest tenth)

Step-by-step explanation:

x=10

The measure of the hypotenuse is 17.029

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have Pythagoras theorem:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Given;

The legs of a right triangle measures 1 cm

The other leg measures 17 cm

Now,

|AC|^2 = |AB|^2 + |BC|^2    

|AC|^2 = |1|^2 + |17|^2    

|AC|^2 = 1 + 289

AC=17.029

Therefore, by pythagoras theorem answer will be 17.029.
