Question restated.
which is not equivalent to d = rt?
r = t/d
r = d/t
t = d/r
d = tr
If we divide both sides of the original equation by t, we are left with r = d/t, so we know that this is true. if we compare this, however, with the first item on the list, we can see that t/d does not equal d/t, so the first item on the list is the wrong one.
We can solve for the value of x by applying the principles of sine and cosines method and laws of the inversed sign.
Given:
sin64°=cosx
Perform sin64° which is equal to 0.8987940463
0.8987940473=cosx
perform inverse sign:
cos-0.8987940473=x
x=26°
Therefore, the value of x is 26°.
So divide 1.89 by 6 to see how much would one pound of grape be
1.89/6=0.315
Then multiply 0.315 (price for one pound of grape ) by 15
0.315*15 =4.725 $for 15 pounds of grape
Answer:
Set 1 Yes
Set 2 No
Set 3 and Set 4 ???
Step-by-step explanation:
Use the converse of the Pythagorean theorem. Square the lengths and see if 2 results add up to the third result.
So, Set 1
100 + 576 = 676 Therefore we have a right triangle
Set 2
16 + 4 ≠ 36 Therefore we do NOT have a right triangle
I will let you do Set 3 and Set 4. OK?
Answer: 4units^2
Step-by-step explanation:
B*H/2
4*2/2= 4
So 4units^2 is the area
