In a triangle, two angles have measures of 45 degrees and 85 degrees. What is the measure of the third angle in this triangle?

Answers

Answer:

50 degrees

Step-by-step explanation:

All three angles in a triangle add up to 180 degrees. If you know the measure of two angles, add them together and subtract the sum from 180.  

45+85=130.  Then, subtract 130 from the total, or 180.   180-130=50. The measure of the third angle of the triangle is 50 degrees.

The amount of motor oil used during the month by the local stock car racing team is g(t) hundred gallons, where t is the number of months past March of a given year.
(a) Write a sentence of interpretation for
g(4) = 13.10.

Answers

The answer is "The local inventory car racing team used 1310 gallons of engine oil in July".

The function consists of 3: input, output, as well as the relationship between the two.The interpretation of a mathematical formalism is to derive important data from a line chart or given symbolic image.Therefore, the amount of oil that the regional sports car racing team is using during the month is G(t), which is 100 gallons, wherein T is the number of months that very last March.

Given:

[tex]\to \bold{g(4) = 13.10}[/tex]

If [tex]\bold{g(4)=13.10}[/tex] means that [tex]\bold{1310 }[/tex] gallons of motor oil was used by the local stock car racing squad in July.So, the final answer is "The local inventory car racing team used 1310 gallons of engine oil in July".

727÷9 Pleaase HEEEELLLPPP!!!!!!!!

Answers

Answer:

80.77777778

Step-by-step explanation:

when dividing 727 by 9, think about how many times does 9 go into 7? none.

next how many times does 9 go into 72? 8 times!

but since we have established 9 cannot go into 7 we need to know how many times does 9 go into 727, since it goes into 72 8 times already try adding a zero behind that 8. So what is 80(9)? it's 720. So the answer would be 720 with a remainder of 7. :)

Which of the following describes an inference?
Please help ASAP!!!

Answers

Answer:

Step-by-step explanation:

I would say it is B

An inference is something that is not directly stated by logical deduction can be a reasonable conclusion to a conclusion drawn.

Example

There was a  person standing in front of me waiting for a bus. I made it guess that it was a girl because she was wearing pink shoes and had a pink phone in her back pocket.

I know that's a bit sexist, but I could not think of another answer. You should, however, note the evidence.

It is B, since inferences always need a educated guess.
