The mass, volume and density of the block of metal are 780 grams, 60 cm³ and 13 g/cm respectively
Volume of a rectangular prismvolume = lwh
where
l = lengthw = widthh = heightTherefore,
volume = 6 × 5 × 2 = 60 cm³
Therefore,
mass = 780 grams
volume = 60 cm³
density = mass / volume
density = 780 / 60
density = 13 grams per centimetre

Please help. I don’t understand what sample space is or how to get to the last answer.
Answer:
13/16
Step-by-step explanation:
A sample space is a collection or a set of possible outcomes of a random experiment.
I have created the sample space for these data and attached it. As you can see there are 16 possible outcomes.
To find the probability that the total showing is greater than 3, simply identify the number of values in the sample space that are greater than 3.
(I have highlighted these in yellow).
Therefore, P(X>3) = 13/16

The two angles inside the triangle added together equals the one other angle that's outside the triangle. Its called an exterior angle.
42° + 5x + 4 = 7x + 6
combine like terms
5x + 46 = 7x + 6
subtract 5x
46 = 2x + 6
subtract 6
40 = 2x

When we left James, he had decided to take a job at Jimmy John's as a sandwich artist with an expected salary of
$31,200 per year. James is really looking forward to the pay increase to help take care of his wife and two kids
After working four weeks, he gets his first check. It is much less than he expected. It turns out he will only get paid
for two weeks because Jimmy John's has a delayed paying process. Everyone gets paid two weeks after they work to
give Human Resources time to prepare the tax information. Since James gets paid every two weeks, a)what is his
gross income for his checks? His pay was much less. It tums out, other people get his money first. He had to pay
Federal Income Tax. b)Use the chart on the back of the test to determine his FIT. He also has to pay State
Income Tax. Oklahoma has a flat 5% tax. c)What is his SIT at 5% of his paycheck? Also, something called FICA
was on his paystub. His employer told him it was a required 6.2% tax for Social Security Retirement and a 1.45%
tax for Medicare when he gets older. d)Find James' Social Security Tax. e)Find his Medicare Tax. What is the
amount of FICA Tax listed as being withheld(add together)? Next came the big schock. Apparently, the
Republican Party still hasn't ended required healthcare. Because of this, James has to pay for group insurance with
Jimmy John's. It is $100 every paycheck, g)what percent of James' gross income is this each month? Finally,
James looks at the other category. It has two deductions listed. First, it has Sandwich Union Body Dues. Annual
dues are $130. h)How much was taken out for SUB dues just this paycheck? The second charged deduction for
other was IRA Retirement. He remembers signing up because Jimmy Johns' offers a matching 5%. If James' is
maximizing the match, i)how much is being taken out for retirement from his paycheck? After going over all the
numbers with his boss, it looks like James' check is correct. j)How much was his net income? If these numbers
remain consistent through the year, k)how much will James bring home for the year? DWhat percent of his
expected salary is this? James was really looking forward to his big paycheck. He thought he would have enough
money to get a loan on a new car. m)Do you think he should try to get the loan or not? n>Explain your opinion.

Evaluate (6 +2i) / (3-i).
Answer:
2(4 + 3i) / 5
Step-by-step explanation:
(6 + 2i) (3 + i) / (3 - i) (3 + i)
=> 18 + 12i + 2i² / 9 - i²
=> 16 + 12i / 10
=> 8 + 6i / 5
=> 2(4 + 3i) / 5
Answer:
(6 +2i) / (3-i) = (6+2i)/(3-i) x (3+i)/(3+i) = (6+2i)(3+i) / (3-i)(3+i) = 6(3+i)+2i(3+i) / (3)^2-(i)^2 = 18+6i+6i+2i^2 / 9-i^2 = 18+12i+2i^2 / 9-i^2 = 6+12i+2i^2 / 3-i^2 = 2+12i+2i^2 / 1-i^2 = 2+12i+2 / 1 = 4+12ianswer.

JKLM is a triangle. Find the measure of angle KL and JM
Answer:
x = 10
m∠K = 90°
y = 15
JM = 65
Step-by-step explanation:
KJ = LM
⇒ x + 31 = 5x - 9
⇒ 40 = 4x
⇒ x = 10
From inspection of the diagram, m∠K = 90° (right angle)
KL = JM
⇒ 4y + 5 = 2y + 35
⇒ 2y = 30
⇒ y = 15
JM = 2y + 35
⇒ JM = 2(15) + 35
⇒ JM = 30 + 35
⇒ JM = 65
Opposite sides of rectangle are equal

Triangle IJK is similar to triangle LMN. Find the measure of side LM. Round your answer to the nearest tenth if necessary.
Answer:
It's either 39.2 or 39.3 (a more accurate answer) because it depends on what you round by. since it's Delta Math, you should get 2 attempts.
Step-by-step explanation:
Since they are similar, they are proportional.
54/11=4.90909091 or 4.9
Multiply 11 by 4.90909091 and you get 54
Multiply 8 by 4.90909091 and you get 39.3
if you multiply by 4.9 you get 39.2

Fiona is x years old thomas is 3 years older than fiona cara is twice as old as fiona the sum of their ages is 51
The ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Fiona who is [x] years old. Thomas is 3 years older than Fiona. Cara is twice as old as Fiona the sum of their ages is 51.
We can write -
Age of Thomas = [y] = x + 3
Age of Cara = [z] = 2x
and
2x + x = 51
3x = 51
x = 17
Age of Thomas = [y] = x + 3 = 20
Age of Cara = [z] = 2x = 34
Therefore, the ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.

Calculate the volume of a right cylinder with a base area of 21.23 cenitimeters and
a height of 3.2 centimeters to the nearest hundredth of a centimeters).
Answer: 67.94 cm^2
Step-by-step explanation:
The volume of a cylinder equals the base area multiplied by the height.
Therefore, the volume would be equal to 21.23cm*3.2cm = 67.936 cm^2
Rounded to the nearest hunderedth, the volume would be 67.94 cm^2
a stock investment of 160 shares paid a dividend of $584 at this rate what dividend would be paid on 270 shares of stock
Answer:
4985.5
Step-by-step explanation:
To start, lets show what we know
160x = 584 where x is the amount paid per stock investment
Find: 270x
Now lets find x
160x = 584
160x/160 = 574/160
x = 3.65
270x = 270(3.65) = 985.5
Here, we have our answer of $985.5 for 270 shares of stock.
