Answer:
no
Step-by-step explanation:
It is close, but not exactly a right triangle.
If it were a right triangle, we would have ...
21² +70² = 73²
We have instead ...
441 +4900 ≠ 5329
5341 ≠ 5329 . . . . . . . . not a right triangle
Step-by-step explanation:
By sum of angles on a straight line = 180°,
we have Angle A + Angle B = 180°,
Angle C + Angle D = 180°, and
Angle E + Angle F = 180°.
Hence Angles A + B + C + D + E + F = (180°) + (180°) + (180°) = 540°.
Answer:
Step-by-step explanation:
16=2(4d-8-2)
4d-10=16/2
4d=8+10
d=18/4
d=9/2
(5,-1) and (2,-4) the solution is where the lines meet
The sales tax rate would be 8%.
To find how much you spent on tax in the total, you'd begin by subtracting the pre-tax notebook from the after tax notebook.
4.86 - 4.50 = 0.36
So now we know that you spent 36 cents on tax. From there, we'd divide our money spent on tax by our pre-tax total.
0.36 ÷ 4.50 = 0.08
This means that the sales tax is 8%.
Hope I could help!
