Finally, you can add them to get 43/100.

Answer 2

43/100
Make both denominators into 100 so that means 3/10 would be 30/100 then you add both so 30/100+ 13/100 only adding the numerators so it will equal 43/100

Answer:

x = 35

Step-by-step explanation:

We can tell that these two angles are supplementary—that means that they add up to 180˚.

So, subtracting 75 from 180, we get 105. That's the value of angle 3x. Now, just divide 105 by 3. That's 35.

By that logic, x = 35.

Answer:

Ans(1) 167 (rounded off)

ans(2) 32 (rounded off)

TLS's major product offerings include academic tutoring, standardized test preparation, and admissions consulting. Demand for standardized test preparation, which accounts for the majority of TLS's revenues, peaks before the most popular test dates. Demand for admissions consulting peaks late in the year, just before application deadlines. Demand for tutoring services varies less than demand for other TLS services, but it is highest near the end of academic semesters. Staff shortages during these times have been a persistent problem. In response, TLS is considering whether to 1) recruit and train a greater number of temporary workers during peak demand times; or 2) partner with a tutoring and testing outsourcing firm that would provide services to TLS customers using the TLS brand. An executive at TLS believes that the best way to measure the number of extra employees that TLS needs is to estimate the number of extra employees each product category requires and then add all of those estimates together. Which of the following points out a flaw in this approach??A. The largest growth area for TLS is governmental contracts, which have buying procedures that are very different from those of other customers.B. TLS currently maintains separate accounting departments in each of its regions. C. To be effective, TLS managers need to be experts in at least one of the products that TLS sells. D. TLS hopes to build sustained relationships with customers, selling the same person academic tutoring standardized test preparation, and admissions consulting. E.
