Answer:
8a=32
Step by Step
Since David is 8x older than Nicole you could write Nicole as the age of a, so then David would be 8a. You are given David is 32 years old so you set 8a equal to 32.
Answer is 4
Nicole is 4 years old
8a=32
divide both sides by 8
Answer is 4
Answer: A, B, D
Explanation:
40/ 160 = 0.25
1/4 = 0.25
22/88 = 0.25
80/330 = 0.2424...
16/64 = 0.25
Step-by-step explanation:
35. 1000 m / 1 km = 10³
Move the decimal point 3 places to the right.
36. 100 cm / 1 m = 10²
Move the decimal point 2 places to the right.
37. 1 mm / 1000 μm = 10⁻³
Move the decimal point 3 places to the left.
38. 1 km / 1000 m × 1 m / 100 cm = 10⁻⁵
Move the decimal point 5 places to the left.
39. 1 Mm / 10⁶ m × 1 m / 10⁶ μm = 10⁻¹²
Move the decimal point 12 places to the left.
40. 100 cm / m × 1000 m / km = 10⁵
Move the decimal point 5 places to the right.
When
you construct parallel lines you have to copy an angle by creating
arcs with a compass. For inscribed polygons you also have to use a
compass in order to be sure that the figure is a regular polygon.
There for the when you are constructing inscribed polygons and
parallel lines, A compass is used to draw arcs.
Answer:
C) A compass is used to copy an angle.
