The mass of a dust particle is approximately 7.5 x 10 –10kilograms and the mass of an electron is 9.1 x 10 –31kilograms. Approximately how many electrons have the same mass as one dust particle?

Answers

Answer 1

Answer:

(7.5 x 10-10 kg) / (9.1 x 10-31 kg) ≅ 8.24 x 1020

Step-by-step explanation:

Divide the mass of one dust particle by the mass of one electron, and that will be your answer.

(7.5 x 10-10 kg) / (9.1 x 10-31 kg) ≅ 8.24 x 1020

If the area of a rectangle is (15x2 - 16x - 15) square feet, and its length is (3x - 5) feet, find its width

Answers

Answer:

255

Step-by-step explanation:

(15x2 - 16x - 15) = 270

(3- 5) = -15

 270

-  -15

= 255

The breadth of the rectangle is (-5x-3).

Area of rectangle

The area of a rectangle is given as the product of its length to its breadth.

[tex]\rm{Area\ of\ Rectangle = Length \times breadth\\[/tex]

Given to us

area of a rectangle = (15x2 - 16x - 15)

length = (3x - 5)

Width

[tex]Area\ of\ Rectangle = Length \times breadth\\(15x^2-16x-15)=(3x-5)\times breadth\\\\(3x-5)\times breadth=(15x^2-16x-15)\\\\breadth = \dfrac{(15x^2-16x-15)}{(3x-5)}\\\\breadth = (-5x-3)[/tex]

Hence, the breadth of the rectangle is (-5x-3).

Is 2.8 greater than or less than 2.78? Pls answer

Answers

2.8 is greater than 2.78 :)


If you look in the tens place and compare the two numbers, you will see that 8 is greater than 7. That’s how you know that 2.8 is greater than 2.78
2.8 is greater than 2.78 because 2.8 would basically be 2.80 so you can just add 0 at the end cause that wouldn’t change anything. So 2.80 you can see is greater than 2.78 because .80 > .78

To find:

The shape and direction of the given function.

Solution:

We have,

[tex]f(x)=(x+7)(x+11)[/tex]

It can be written as

[tex]f(x)=x^2+11x+7x+77[/tex]

[tex]f(x)=x^2+18x+77[/tex]

It is a quadratic function and the power of [tex]x[/tex] is 2 so the graph of this function is a vertical parabola.

The leading coefficient is positive so the parabola opens upward.

Therefore, the given function is a vertical parabola that opens upward.

2. there's no relationship being displayed because there's no image

3 theyre vertical angles

4 is 51

5 is 41

6 is 59

Step-by-step explanation:

All you need to do to find the missing angles is subtract from whatever. so the first one is a straight line so all you would do is 180-40 for the one that kind of looks like an x just know they're going to be the same angle when they're like that and for number four you can see it's a 90° angle so you subtract 90 - 39 so that you can get the answer that way
