To condition in which we can justify if the forces are pulling at right angles to each other is that the sum of the squares of the two lesser number should be equal to the square of the third number.
For the first set: 12 lb, 13lb, 19lb.
12^2 + 13^2 <span>≠ 19^2
For the second set: 15 lb, 36 lb, 39 lb
15^2 + 36^2 = 39^2
The first pair of forces do not pull at a right angle while the second do.
Thus, the answer is letter B. </span>
Answer:
length= 24 inches
width= 7 inches
Step-by-step explanation:
Start by writing down what you know.
width= w
length= 3w+3
Then, we can substitute into the perimeter of a rectangle equation, P=2l+2w.
62= 2(3w+3) + 2(w)
62=6w+6+2w
62=8w+6
56=8w
7=w
Now, plug this into our original equations for length and width:
width=7
length= 3(7)+3, so 24
There is no graph to choose from, but the one you are looking for should look like the attached photo.
Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
Answer:
C
Step-by-step explanation:
Good Luck and I hope you do well :)
100%/x%=60/18
<span>(100/x)*x=(60/18)*x </span>
<span>100=3.33333333333*x </span>(3.33333333333)
<span>100/3.33333333333=x </span>
<span>30=x </span>
x=30
<span>now we have: </span>
<span>18 is 30% of 60</span>
