What is the value of x? ​

Mathematics
1 answer:
Aliun [14]3 years ago
7 0

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

C6.1 PA1 short term decision Artisan Metalworks has a bottleneck in their production that occurs within the engraving department
laila [671]

Answer: $4850

Step-by-step explanation:

The other information related to the question is:

Direct materials = $3.50

Direct labor = $1.10

Variable overhead = $0.45

Fixed overhead = $2.80

Total = $7.85

Based on the information given in the question, the increase in the profit will be calculated as the contribution from the 3000 extra units minus the worker's salary.

Contribution from 3000 units will be:

= (Selling price - Direct materials - Direct labor - Variable overhead) × 3000

= ($25 - $3.50 - $1.10 - $0.45) × 3000

= $19.95 × 3000

= $59850

Increase on Profit:

= $59850 - $55000

= $4850

Which of the following sets of lengths could not be the side lengths of a triangle?
docker41 [41]
To find out if the three side lengths can create a triangle, the three smaller lengths must be greater than the longer length.

\bf~Option~A

\sf~3~meters,5~meters,7~meters

\sf3+5=8>7

So this can create a triangle.

\bf~Option~B

\sf1~yard,1.25~yards,1.5~yards

\sf1+1.25=2.25>1.5

So this can create a triangle.

\bf~Option~C

\sf5~inches,10.5~inches,17~inches

\boxed{\sf5+10.5=15.5

So this cannot create a triangle.

\bf~Option~D

\sf15~millimeters,18~millimeters,30~millimeters

\sf15+18=33>30

So this can create a triangle.

Therefore, your answer is Option C.

7. Find the distance between the points (13, 8) and (-12, 6)
Alik [6]

9514 1404 393

Answer:

  √629 ≈ 25.08

Step-by-step explanation:

The distance formula is useful for this.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((-12 -13)² +(6 -8)²) = √(625 +4) = √629 ≈ 25.08

The distance between the points is about 25.08 units.
