Answer:
2 hours 30 minutes
Step-by-step explanation:
Effort is measured in people-hours per house. Here, the effort to deliver one leaflet is ...
(3 people)(2.5 hours)/(270 houses) = 1/36 people-hours/house
Then the number of hours (h) for 5 people and 450 houses is ...
(5 people)(h hours)/(450 houses) = 1/36 people-hours/house
h = (1/36)(450/5) = 2.5
It will take 2 hours 30 minutes to deliver to 450 houses.
_____
Alternate solution
The time is (assumed) inversely proportional to the number of people, so increasing the number of people from 3 to 5 multiplies the time by 3/5. The time is proportional to the number of houses, so increasing the number of houses from 270 to 450 multiplies the time by 450/270 = 5/3. The time for the second task is (3/5)(5/3) = 1 times the time for the first task.
2 1/2 hours is 2 hours 30 minutes.
List the steps that you will do in order to solve for 39 ÷ (12 + 1)− 2 × (4 + 15).
9514 1404 393
Answer:
simplify parenthesesdivide 39/13multiply 2(19)subtract 3-38Step-by-step explanation:
The order of operations tells you to evaluate parentheses first.
Step 1: simplify (12+1) and (4+15)
39÷13 -2×19
Then it tells you to do multiplication and division, left to right.
Step 2: divide 39÷13
3 -2×19
Step 3: multiply 2×19
3 -38
Finally, addition and subtraction are done, left to right.
Step 4: subtract 38 from 3
-35
Find the range and interquartile range (IQR) of the data set in the box plot.
11,7, 24, 7, 16, 18, 27, 8, 13, 14, 24, 30
Answer:
Range = 23
IQR= 14.5
Step-by-step explanation:
Range is the biggest number- smallest number
so 30-7=23
IQR - Interquartile range = upper quartile - lower quartile
24-9.5=14.5

Convert each percent into a fraction and decimal:
133 1/2%
87 1/3%
0.01%
8 1/3%
9514 1404 393
Answer:
267/200 = 1.335131/150 = 0.8733...1/10,000 = 0.00011/12 = 0.0833...Step-by-step explanation:
It might be helpful to think of the % symbol as being interchangeable with /100.
133 1/2% = (133 1/2)/100 = 267/200 = 1.335
87 1/3% = (87 1/3)/100 = 262/300 = 131/150 = 0.8733333... (repeating 3)
0.01% = 0.01/100 = 1/10000 = 0.0001
8 1/3% = (8 1/3)/100 = 25/300 = 1/12 = 0.0833333... (repeating 3)
What is 5% as a fraction?
Answer:
The answer would be 5/100 or 1/20 in it's simplest form
Step-by-step explanation:
So let's say you have only 5% of a pie and the rest of your family gets the rest, if you put that in a form of a fraction, the answer would be 5 over 100 (5/100). But if you simplify, the answer would be 1/20 since 5 goes into 5 once and 20 goes into 100 5 times.

Enter the ratio equivalent to sin (Y).
9514 1404 393
Answer:
5/13
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relation ...
Sin = Opposite/Hypotenuse
The side opposite Y is the one that does not have Y in its name: XZ. The hypotenuse is the longest side: YX. Then your ratio is ...
sin(Y) = XZ/YX
sin(Y) = 5/13
Mr. Crowder wants to get a new fit for class. He finds some Gucci glasses on sale for 20% off. If the glasses originally cost $240, what will the sales price be?
A)$192
B)$48
C)$288
D)$220
Answer:
A) 192
Step-by-step explanation:
20% = 0.2
240(0.2) = 48
This means $48 will be taken from the original price so:
240 - 48 = 192
Journal entries to record cash dividends are made on the:

B. Declaration date, record date, and payment date.
C. Declaration date and record date.
D. Declaration date and payment date.
Journal entries to record cash dividends are made on the:
D: Declaration date and payment date.
The ratio of dividends relative to the net income that is earned during a period of time is referred to as dividend payout ratio.
These dividends are defined as cash payments made to the stockholders out of the profits generated during that same period.
The higher the payout ratio, the lower are the earnings retained by the company and the lower the payout ratio, the higher the earnings retained by the company.
Now, when entering these cash dividends into a journal, the date of declaration of the dividends and the date of payment must be recorded.

The product of two consecutive even integers is 48. Find the integers
Answer:
The two consecutive integers are 6 and 8 or -8 and -6.
Step-by-step explanation:
The product of two consecutive even integers is 48, and we want to find the two integers.
We will let x represent the first even integer.
Then the consecutive even integer will be (x + 2).
Its product is 48. Therefore:
[tex]x(x+2)=48[/tex]
Solve for x. Since this is a quadratic, we should get one side to equal to 0. Expand:
[tex]x^2+2x=48[/tex]
Subtract 48 from both sides:
[tex]x^2+2x-48=0[/tex]
Factor:
[tex](x+8)(x-6)=0[/tex]
Zero Product Property:
[tex]x+8=0\text{ or } x-6=0[/tex]
Solve for each case:
[tex]x=-8\text{ or } x=6[/tex]
Therefore, our two consecutive integers are 6 and 8 or -8 and -6.

How much wrapping paper would you need to cover a rectangular box that is 6 inches by 8 inches by 3.5 inches?
Answer: 192 inches^2
Step-by-step explanation:
Basically what they want you to find is surface area which is adding the area of all the sides.
6*3.5*2+8*3.5*2+6*8*2=SA
42+56+96=SA
SA= 192 inches^2
A person invests $1,000 into stock of a company that hopes to go public in one year. The probability that the person will lose all his money after one year (i.e. his stock will be worthless) is 35%. The probability that the person’s stock will still have a value of $1,000 after one year (i.e. no profit and no loss) is 60%. The probability that the person’s stock will increase in value by $10,000 after one year (i.e. will be worth $11,000) is 5%. Find the expected profit after one year.
Answer:
The expected profit after one year is of $150.
Step-by-step explanation:
Probabilities after one year:
35% probability of losing $1,000, that is, 35% probability of a profit of -$1,000.
60% probability of still having a value of $1,000, that is, 60% probability of a profit of $0.
5% probability of a increase in value of $10,000, that is, a profit of $10,000.
Find the expected profit after one year.
Each value is multiplied by its probability. So
[tex]E = -0.35*1000 + 0.6*0 + 0.05*10000 = 150[/tex]
The expected profit after one year is of $150.

Find the area of an octagon with a radius of 11 units. Round your answer to the nearest hundredth. NO LINKS
Answer:
342.24 units²
Step-by-step explanation:
The area of one of the 8 triangular sections of the octagon is ...
A = (1/2)r²·sin(θ) . . . . . where θ is the central angle of the section
The area of the octagon is 8 times that, so is ...
A = 8·(1/2)·11²·sin(360°/8) = 242√2
A ≈ 342.24 units²
