Answer:
How to measure an angle with a protractor:
1 Place the midpoint of the protractor on the VERTEX of the angle.
2 Line up one side of the angle with the zero line of the protractor (where you see the number 0).
3 Read the degrees where the other side crosses the number scale.
The rules of significant figures are: 1. all non zeros are significant. 2. trailing zeros are significant. 3. zeros between non-zeros are signifincant. Hence, applying these to the given.
A. 4 sig figs
B. 1 sig fig
C.6 sig figs
D.1 sig fig
The equation for decreasing a price by 20% is
original price x 0.8 = sale price
Here, we can fill in the sale price so
original price x 0.8 = 51.44
This can be rearranged to show:
51.44 ÷ 0.8 = original price
So the original price was $64.30
Answer = B - $64.30
19z-7 - ( 5z-9 + <span>8z+3)
= 19z - 7 - (13z - 6)
= 19z - 7 - 13z + 6
= 6z - 1
answer
remaining side = </span> 6z - 1
