Answer: The answer is (D) 132^\circ.

Step-by-step explanation: We are given a figure where the line segments AE and RV are intersecting at the point N. We are to find the measure of \angle ENV.

Also, given that

\angle ANR=(8x+12)^\circ,\\\\\angle ENV=(5x+57)^\circ.

Since the line segments AE and RV intersect at N, so we have

\angle ANR=\angleENV~[\textup{vertically opposite angles}]\\\\5x+57=8x+12\\\\\Rightarrow8x-5x=57-12\\\\\Rightarrow3x=45\\\\\Rightarrow x=15.

Therefore,

\angle ENV=(5\times 15+57)^\circ=(75+57)^\circ=132^\circ.

Thus, (D) is the correct option.

Novosadov [1.4K]

Answer:

<u>42 Hours.</u>

Step-by-step explanation:

As an equation where y is the total pages and x is hours of class:

y=1+1x since she started with 1 page and does 1 page per hour.

Setting the total pages she needs as 43 (y=43) we get:

43=1+1x

Subtract one on both sides

42=1x

The 1 doesn't need to be written so

x=42

Therefore, it'll take her 42 hours to write all those notes.

At a college, 72% of courses have final exams and 46% of courses require research papers. Suppose that 31% of courses have a res
beks73 [17]

Answer:

0.25

Step-by-step explanation:

72% of courses have final exams and 46% of courses require research papers which means probability of 0.72 for courses that have final exams and 0.46 for courses that require research papers.

31% of courses have a research paper and a final exam, which means probability of 0.31 for both courses with exams and research papers, using Venn diagram approach, find picture attached to the solution.

P(R or E) = P(R) + P(E) - P(R and E), which gives:

P(R or E) = 0.15 + 0.41 - 0.31

P(R or E) = 0.25.

Firdavs [7]
Ok so 1.5 is pins and 6.5 is t shirts so you multiply 1.5 x 20 and 6.5 x 5 so for pins= $30 and T-shirts= $32.50 and you times both those numbers by 3 so for pins you get $90 and T-shirts you get $97.50. Finally you add them and get $187.5 so the answer is $187.5 for the project.

stealth61 [152]

The statement below best describes the value the base 0.86 is that "the car Trevor purchased depreciates at a rate of 86%".

  • It should be noted thàt depreciation occurs when we buy an equipment or machine and use it. With time, due to wear and tear or usage, the value reduces.

  • The value of the car will not appreciate but rather depreciate. Therefore, the correct option is "the car Trevor purchased depreciates at a rate of 86%".

In conclusion, the correct option is D.
