Solve the equation :6/x+10=2/15
Answer:
x = - 45 / 74
Step-by-step explanation:
6 / x + 10 = 2 / 15
6 / x = 2 / 15 - 10
6 / x = 2 / 15 - 150 / 15
6 / x = - 148 / 15
6 = ( - 148 / 15 ) x
6 ( 15 / - 148 ) = x
x = 90 / - 148
x = - 45 / 74

23 What is the area of the shape?(1 Point) O 25 cm² O 50 cm² O 100 cm² O 150 cm² 5 cm 15 cm 5 cm, 10 cm 26°C Mostly clear
The area of the given figure is 100 cm².
In the above figure, we calculate total area by dividing the figure into two sub figures wherein we get a square portion of side 5 cm and a rectangular portion of length 15cm and breadth 5 cm. The area of the square and rectangle can be given as product of their two sides that is length multiplied by breadth.
Area of square portion = 5*5 = 25 square centimeter
Area of rectangular portion =15*5 = 75 square centimeter
Hence total area of the figure = Area of square portion + Area of rectangular portion.
Therefore, Total area of figure = 25 + 75 = 100 cm².

Step-by-step explanation:
The "experimental probability" is the ratio of actual outcomes of interest to the number of trials. It is based on actually performing the selection over and over some number of times. The "theoretical probability" will be the fraction that is the outcomes of interest divided by the total number of possible outcomes.
We note that Mel's purse contains a total of 6 +8 +4 +7 = 25 coins. The theoretical probability of selecting any given coin is then 1/25.

A. The experimental probability of selecting a dime is ...
number of dime outcomes / number of trials = 30/150 = 1/5
B. The theoretical probability of selecting a dime is ...
(4 dimes)/(25 coins) = 4/25
C. The assumption in probability experiments is that randomly selected outcomes will always approach the theoretical probability in their frequency of occurrence.
See the attachment for the appropriate answer choices.

A. The experimental probability of selecting a penny is ...
number of penny outcomes / number of trials = 45/200 = 9/40
B. The theoretical probability of selecting a penny is ...
(6 pennies)/(25 coins) = 6/25
C. The difference between these values is ...
6/25 -9/40 = 48/200 -45/200 = 3/200
See the attachment for the appropriate answer choices.

Joey bought 8 books. Some books cost $12 each the rest cost $18 each he spent a total of 108 which of the following system of linear equation could represent the given situation?
Answer: It's A
Step-by-step explanation: X + Y is the total books, which should equal 8. Some books treat them as X, while the rest treat them as Y. You end up with 12x+18y=108.
If m is the midpoint of CD, CM= 4x-5, and md=2x +5, find CM
Answer:
CM = 15
Step-by-step explanation:
since M is the midpoint of CD , then
CM = MD , that is
4x - 5 = 2x + 5 ( subtract 2x from both sides )
2x - 5 = 5 ( add 5 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Then
CM = 4x - 5 = 4(5) - 5 = 20 - 5 = 15
Hahn Company uses a job-order costing system. Its plantwide predetermined overhead rate uses direct labor-hours as the allocation base. The company pays its direct laborers $18,50 per hour. During the year, the company started and completed only two jobs-- Alpha, which used 62,300 direct labor-hours, and Job Omega. The job cost sheets for the these two jobs are shown below.
Answer:
1. $7 per DLH
2. Total Job Cost = $1,638,000
Step-by-step explanation:
Note: Question is incomplete and similar question is attached as picture below
1. Direct Labor Hours - Omega = $331,800 (Direct Labor) / $14 per Hour (Direct Labor Rate per hour)
Direct Labor Hours - Omega = 23,700 hours
Predetermined Overhead Rate = $165,900 (Applied Manufacturing Overhead) / 23,700 (Direct Labor Hours)
Predetermined Overhead Rate = $7 per DLH
2. Job Cost Sheet for Job Alpha
Direct Material $428,400
[$1,638,000 - ($806,400 + $403,200) ]
Direct Labor $806,400
(57,600 hrs * $14)
Manufacturing Overhead applied $403,200
(57,600 hrs * $7)
Total Job Cost $1,638,000
