Answer:
The length of segment TR with T(-4,5) and R(2, -1) is 8.49
Step-by-step explanation:
We need to find the length of segment TR with T(-4,5) and R(2, -1)
The length of segment can be found using distance formula.
The distance formula is: 
Putting values and finding length
We have: 

We found Distance = 8.49
So, The length of segment TR with T(-4,5) and R(2, -1) is 8.49.
Answer:
136
Step-by-step explanation:
You can do 8×10=80
And 8×7=56
Add the two together
Because 10+7=17 you split it, but multiplied it by the 8.
80+56=136
Answer:
Step-by-step explanation:
i believe this is multiplication so. just multiply 12 3/4 x 2/5. The answer to that would be 12 6/20. Now let's simplify. you can divide this fraction to the fraction 2/2. 12 6/20 divided by 2/2 equals to 12 3/4. I hope this right, and I really hope you get an A on your test.
If it's division than here's the steps. KCFM (keep, change, flip, multiply) keep 12 3/4, change the division symbol to multiplication, and flip the fraction 2/5 to 5/2. last step multiply. 12 15/8. If you can simplify that then simplify it. I don't see anyone to simplify it so your okay.
What is 40/100 as a decimal?
To write 40/100 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 40 by 100 what we write down as 40/100 and we get 0.4
And finally we have:
40/100 as a decimal equals <span>0.4</span>
Answer:
about 0.7 miles
Step-by-step explanation:
When you draw a diagram of the problem, you see that the shortest distance back to the course is the distance traveled times the sine of the angle:
distance off course = (14 mi/h)×(2 h)×sin(1.4°) ≈ 0.684 mi
The ship is about 0.7 miles from its intended course.
