∠B = 64.62°

Step-by-step explanation:

cos B = 3/7 = 0.4286

∠B = 64.62°

Answer:

30 degrees ; 150 degrees

Step-by-step explanation:

1) rememeber that two supplementary angles have their sum equals to 180 degrees

2) write an equation with the given information

x + 5x = 180

2) solve the equation

- added up the terms with x

6x = 180

- divide the two members by 6

x = 30

- find the second angle by multiplying 30 by 5

150

Answer:

y=-x+4

Step-by-step explanation:

3-5/1-(-1) = -1

(y-(-1)) = -1(x-5)

y+1 = -x+5

y= -x +5-1

y= -x + 4

Answer:

C: monomial

Step-by-step explanation:

 You need to classify the polynomial. But before we start, let's recall the basic classifications of polynomials:

Monomials

Binomials

Trinomials

Polynomials

What are monomials?

 - expressions with only one term

What are binomials?

 - expressions with two terms

What are trinomials?

- expressions with three terms

What are polynomials?

- expressions with four or more terms

30x is an expression with only one term, so it's a monomial.

∴ letter C: monomial

Step-by-step explanation:

Answer:

10 hours and 20 minutes.

Step-by-step explanation:

We can find out how many hours of sleep Tucker gets every night by counting in one-hour intervals.

One hour from 8:25 is 9:25.

9:25, 10:25, 11:25, 12:25, 1:25, 2:25, 3:25, 4:25, 5:25, 6:25.

This is 10 hours.

Now we count in ten-minute intervals to get to 6:45

6:35, 6:45.

This is 20 minutes.

Therefore, Tucker gets 10 hours and 20 minutes of sleep each night.

This is equivalent to 620 minutes.

===================================================

Explanation:

The user purrugh has a great answer. I'll provide a slightly different approach.

The timespan from 8:25 PM to 9:00 PM is 35 minutes. Note how adding 35 minutes to 25 past the hour gets us to 25+35 = 60 minutes, so we're at the top of the hour now, and at 9 o' clock on the dot.

Then from 9 PM to 12 midnight is a gap of 3 hours (because 12-9 = 3). From midnight to 6 AM is another 6 hours. So far we have 3+6 = 9 hours, plus the additional 35 minutes mentioned earlier. The duration so far is 9 hours, 35 minutes. We still have to account for another 45 minutes, since we want to get to 6:45 AM and not 6:00 AM.

Note how 35+45 = 80, which is over 60. This means 35 min + 45 min = 80 min = (60 min) + (20 min) = 1 hr, 20 min

That "1 hr, 20 min" is added onto the "9 hours" from earlier and we arrive at 10 hours, 20 minutes as the final answer

-----------------------------

Yet another approach is to do everything in minutes, and then convert to hours,minutes format at the very end.

Again the gap from 8:25 PM to 9:00 PM is 35 minutes. From 9 PM to midnight is 3 hours, or 3*60 = 180 minutes. We have a duration so far of 35+180 = 215 minutes.

From midnight to 6 AM is 6*60 = 360 minutes. The duration has been updated to 360+215 = 575 minutes. Finally, from 6 AM to 6:45 AM is the last gap of 45 min to get us to 575+45 = 620 minutes.

Tucker slept a total of 620 minutes. Let's convert that to hours,minutes format. Note how 620 = 600+20 and how 600/60 = 10. Meaning that 600 minutes = 10 hours. Therefore,

620 min = (600 min) + (20 min) = 10 hours, 20 minutes

Answer:

59

Step-by-step explanation:

These angles make linear pair

so angle 4 +60+61=180

Angle 4 = 180-121 = 59
