Which fraction shows the simplest form for 4/12 A.1/4 B.12 C.1/2 D.1/3

Answers

Answer 1

Answer: 4/12 can both go into 4. 4 divided by 4 is obviously 1, so the numerator is 1.12 divided by 4 is 3 so the denominator is 3.
The answer is 1/3 or D

Given that tan θ = –8∕15 and θ is in quadrant IV, find sin θ. Question 19 options: A) 15∕17 B) –15∕17 C) –8∕17 D) 8∕17

Answers

Answer: C

Step-by-step explanation:

In the quadrant IV, it is only a cos θ that is positive.

Given that tan θ = –8∕15

Where tan θ = opposite ÷ adjacent

Where opposite = 8 and adjacent = 15

We can find the hypothenus by using pythagorean theorem

Hypothenus = sqrt(15^2 + 8^2)

Hypothenus = sqrt(289)

Hypothenus = 17.

Sin θ = opposite ÷ hypothenus

Sin θ = 8/17

Since Sin θ is also negative in the fourth quadrant, therefore

Sin θ = - 8/17

Option C is correct.

Amy had homework for math,science,and history.she spent 1/3 of her time working on math and 1/4 of her time working on science.

Answers

First we need to multiply to make the fractions have equal denominators so we can add/subtract.

math: 1/3 x 4/4=4/12
science: 1/4 x 3/3=3/12

Now we can find the time she spent on history (I assume this is what you are looking for)

Total time-math time-science time=history time
12/12-4/12-3/12
=5/12

Amy spent 5/12 of her time working on history.

So,

I will be assuming the same thing as the other user.

First, we have to convert the fractions so that they have common denominators.

$(1)/(3) * (4)/(4) = (4)/(12)$

$(1)/(4) * (3)/(3) = (3)/(12)$

Now we add the fractions together.

$(4)/(12) + (3)/(12) = (7)/(12)$

Now, to find the fraction of the time that Amy spent on history, we need to subtract the sum of the time she spent in math and science from one whole.

$(12)/(12)-(7)/(12)=(5)/(12)$

Amy spent 5/12 of her time working on history.

2(36-4t) t= 3.4

Answers

Since we know that t = 3.4 you put 3.4 where the t is.

2 (36 - 4 × 3.4) So what you do first is multiply 4 and 3.4 which gives you 13.6

2 (36 - 13.6) then you subtract 36 and 13.6 which gives you 22.4

2 (22.4) then you multiply 2 and 22.4 which is 44.8.

So your answer is 44.8
