Answer:
If the mass of one electron is 9.11 x 10-28 g, and you are looking for the mass of a mole of electrons, you need to understand Avogadro's number. One mole is 6.02 x 1023 particles. So you will have to multiply (6.02 x 1023) x (9.11 x 10-28 g) to get your answer of 5.48 x 10-4 grams (answer rounded to significant figures)
Step-by-step explanation:
1.2 x 10¹ times greater is the mass of a carbon-12 atom than the mass of a neutron
What is Division?A division is a process of splitting a specific amount into equal parts.
To find the ratio of the mass of a carbon-12 atom to the mass of a neutron, we can divide the mass of carbon-12 by the mass of a neutron:
(1.99×10⁻²³ grams) / (1.68×10⁻²⁴ grams)
= 11.8 grams
This means the mass of a carbon-12 atom is 11.8 times greater than the mass of a neutron. Written in standard notation and rounded to the nearest tenth, the answer is 1.2 x 10¹
Hence, 1.2 x 10¹ times greater is the mass of a carbon-12 atom than the mass of a neutron

Bongeka purchased a new refrigerator and were expected to pay R1 684,00 five months ago and another R1 323,00 in eight months’ time. She could not make the payment five months ago, but after receiving a bonus at work, she rescheduled to repay the loan in two equal payments, the first due in two months and the second due in five months’ time. The payment at month five will settle the debt, therefore, the settlement date is month five. The debts and payments are subject to the same interest rate of 11,4% per annum, compounded monthly.
The discount factor computed shows that the value of each payment will be $1546.
How to calculate the payment?The following can be deduced from the information:
Payment due in 5 months = $1684
Payment due in 8 months = $1323
Annual interest = 11.40%
Monthly interest rate = 11.40%/12 = 0.95%
Present value of payment due 5 months ago = $1684 + (1 + 0.95%)⁵ = $1765.52
Present value of payment due 8 months ago = $1226.62
Total present value = $1765.52 + $1226.62 = $2992.14
After rescheduling, the payments will be in 2 months and 5 months.
Discount factor for payment due in 2 months = 0.9813
Discount factor for payment due in 5 months = 0.9538
Combined discount factors= 0.9360
Therefore, the value of each payment will be:
= $2992.14/(1 + 0.9360)
= $1546

What is slope? Write a conclusion about the ratio and slope.
The slope of the graph is $15 per hour. The linear function is given by y = 15x
What is a linear function?A linear function is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept
The graph passes through the point (1, 15) and (8, 120) is:
y - 15 = [(120 - 15)/(8 - 1)(x - 1)
y = 15x
For 20 hours; y = 15(20) = $300
If the person got a $50 bonus and also worked some hours, the graph would change because the y intercept would be 50.
If the person got a $2 per hour rate, the graph would change because the slope would be 2.
The slope of the graph is $15 per hour.

Write the slope-intercept for of the equation of the line with that passes through the point (2,-8) and is perpendicular to 2x+3y=15
Answer:
y = 3/2 x - 11
Step-by-step explanation:
Recall that a perpendicular line to the expression:
2 x + 3 y = 15
3 y = - 2 x + 15
y = - 2/3 x + 15/3
is going to have a slope equal to the opposite of the reciprocal of the original (-2/3) slope. So, the slope of the perpendicular line must be: 3/2.
We use this value in a general point-slope form of a line, where we use the point (2, -8) :
y - (-8) = 3/2 (x - 2)
y + 8 = 3/2 x - 3*2/2
y + 8 = 3/2 x - 3
y = 3/2 x - 3 - 8
y = 3/2 x - 11
