The length of each side is 4cm
It is the "structural detailer".
The detailer takes a structural drawing, isolates each piece of steel required to erect the structure. She will design the connections, including the number of angle clips and bolts required, the type, amount and length of weld to attach the connecting elements to the main piece. Field weld must be avoided wherever possible to avoid expensive quality control requirements.
Each separate piece of steel to be fabricated is shown on a separate plan/diagram so that the shop can distribute work to the appropriately skilled worker. The detailer also has to think about erection procedure in such a way that the pieces as fabricated can all fit together in an orderly fashion.
She is also responsible for the integrity of the connections, which often had been the cause of many structural failures.
We can see that the structural detailer is a highly skilled job with lots of responsibilities. Unfortunately the job has not been given as much credit as it deserves, and is often not even known to many in the field.
A decrease of 2% means only 98% of the original value lasts. Therefore Hal should multiply with 98%
To convert percentages to decimals, one has to divide by 100, and therefore
98% = 98/100 = 0.98.
Hence, Hal should multiply with 0.98.
Answer: The answer would be the 2nd choice. 2 4/5 is the answer. Step by-step explanation:
For 1 miles distance : 7/10 of a mile she runs and 3/10 she walks.
For 4 miles distance:(4 times the previous distance) she will run:
4*(7/10)= 18/20 = 2.8
2.8 as a mixed number/fraction is 2 4/5 therefore the answer is 2 4/5.
You multiply each term by each term when expanding double brackets, so:
-2x × 9x = -18x^2
-2x × -3y = 6xy
8y × 9x = 72xy
8y × -3y = -24y^2
Now you combine the like terms to get
-18x^2 + 78xy - 24y^2
I hope this helps!
