The mass of an electron is approximately 9 × 10-28 grams, while the mass of a neutron is approximately 2 × 10-24 grams. Which of the following is true?The mass of a neutron is approximately 2,000 times the mass of an electron.

The mass of a neutron is approximately 10,000 times the mass of an electron.

The mass of a neutron is approximately 20,000 times the mass of an electron.

The mass of a neutron is approximately 1,000 times the mass of an electron.

Answers

We simply divide the Mass of Neutron by Mass of electron

= 2 × 10⁻²⁴ / (9 × 10⁻²⁸)

= (2/9) × 10⁻²⁴ ⁻ ⁻²⁸

= (2/9) × 10⁻²⁴ ⁺ ²⁸

≈ 0.2222... × 10²⁸ ⁻ ²⁴

≈ 0.2222 × 10⁴

≈ 2222

This is approximately 2000 times.

So:

The mass of a neutron is approximately 2,000 times the mass of an electron

The first option. I hope this explains it.

Answer:

The mass of a neutron is approximately 2,000 times the mass of an electron

Step-by-step explanation:

= 2 × 10⁻²⁴ / (9 × 10⁻²⁸)

= (2/9) × 10⁻²⁴ ⁻ ⁻²⁸

= (2/9) × 10⁻²⁴ ⁺ ²⁸

≈ 0.2222... × 10²⁸ ⁻ ²⁴

≈ 0.2222 × 10⁴

≈ 2222

This is approximately 2000 times.

Help to answer 2 & 3 Pablo and Jasmine had just started studying systems of linear equations in algebra. They looked at Pedro's drawing and said, "We could write that as a system of equations." Let t be the price of each taco and d be the price of each drink. - Write an equation that represents the cost of Pablo's order. (6T + 2D = 9) - Write an equation that represents the cost of Jasmine's order. (4T + 2D = 7) 2. What operations with the equations from part (1) match your way of using Pedro's sketch to find the prices t and d? 3. Why do the operations make sense?

Answers

Answer:

Step-by-step explanation:

The equation for Pablo's order is given as 6T+2D=9 or 6T+2D-9=0

While the equation for Jasmine's order is given as 4T+2D=7 or 4T+2D-7=0

Subtracting Jasmine's equation from Pablo's

6T+2D-9-(4T+2D-7)=0

This gives us

6T+2D-9-4T-2D+7=0

The reduces to

2T-2=0

Dividing all through by 2 gives

T-1=0

Therefore

T=1

Substituting the value for T into any of the equations of either Pablo and Jasmine

Using Pablo's

6T+2D=9

6(1)+2D=9

2D=9-6

2D=3

There D= 3/2

Answer:

Carlita saw 5 times as many robins as cardinals while bird watching. She saw a total of 25 birds. How many more robins did she than cardinals?

Answers

Carlita was either sipping the hot chocolate while she was out, or else
approximating the numbers. The exact number she reported is not
possible. To see why, I'll do it strictly by the math:

Robins = 5 times
Cardinals = 1 time

Total birds = 6 times

6 times = 25 birds

Divide each side by 6 : 1 time = 25/6 = 4-1/6 birds

Robins = 5 times = 20-5/6 of them
Cardinals = 1 time = 4-1/6 of them

Total: (20-5/6) + (4-1/6) = 25 birds.

How many more robins than cardinals = (20-5/6) - (4-1/6) = 16-2/3 more.

The math works out fine. But if the numbers she reported are true,
then some of what she saw was partial birds ... legs, or feathers,
things like that. Eeeew. I don't want to talk about it.

20 because 5x5=25 so she saw 5 x as many if you divide 5 and 25 you get five

Y=2x squared +4x-1 . help me

Answers

Answer:

y = 9/8 for part one of solving y in this equation .

Step-by-step explanation:

Answer:

x= (√2y+6/2)-1

Step-by-step explanation:

Swap sides so that all variable terms are on the left hand side.

2x^2+4x−1=y

Subtract y from both sides.

2x^2+4x−1−y=0

Using quadratics formula:

x=-4±√4²-4*2(y-1)/2*2

x= −4±2√2y+6/4

Next solve the equation by using either ± = subtraction or addition

I am using ± = addition. This means I add -4 to 2. From there I simplify equation.

x= (√2y+6/2)-1

Not sure if this means to find x, but I think this is what it would be.

A group of 100 people, some students and some faculty, attended a museum opening. Each student paid $10 per person for entrance to the museum and each of the faculty paid $25 per person for entrance. If the total paid, for all 100 people, was $1300, how many students attended the museum opening?

Answers

The number of students who attended the museum opening is 80.

What is a linear equation?

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Given, A group of 100 people, some students and some faculty, attended a museum opening.

Assuming no. of students to be x and no. of faculty to be y.

∴ x + y = 100...(i)

Each student paid $10 per person for entrance to the museum and each of the faculty paid $25 per person for entrance and the total cost is $1300.

∴ 10x + 25y = 1300...(ii)

Now multiplying eqn(i) by 10 we get 10x + 10y = 1000...(iii)

Subtracting eqn(iii) from eqn(ii) we get 15y = 300 ⇒ y = 20 and substitting value of y in eqn(iii) we get x = 80.
