Answer:
(a) 3
(b) 4
(c) 3
Step-by-step explanation:
To find the number of significant figure, ignore all zeros on the left and count the remaing digits.
(a) ignore 0.0, so 590 is 3 s. f.
(b) no zeros to the left, so 4 s. f.
(c) ignore 0.00, so 122 is 3 s. f.
You will have to type it into Microsoft word first, type a number or algebraic expression into a Word document. Press the "Ctrl," "Shift" and "=" keys on your keyboard to turn on the Superscript mode. Enter another number or expression signifying the exponent.
Hope this helps! :)
Answer:
x = 8
Step-by-step explanation:
For the triangles to be congruent, then the legs
ED = AB, that is
4x + 2 = 34 ( subtract 2 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
Answer:
567 mph
Step-by-step explanation:
The speed will actually just be the slope of the line. Slope is change in y-coordinates over change in x-coordinates. We can pick any two points for this; let's just do (1, 567) and (2, 1134).
Slope = (1134 - 567) / (2 - 1) = 567 / 1 = 567
The speed is thus 567 miles/hour.
I think it is - 22
