(3.9 * 10^33)(1.55 * 10^7)
3.9 * 1.55 = 6.045
10^33 * 10^7 = 10^40
6.045 * 10^40 <=== ur answer for the 1st one
1.6 * 10^-3 = 1.6 * 1 / 10^3 = 1.6/1000 = 0.0016 <== its probably this one...the 1.6 * 10^-3
Answer : 58 square units.
Tip : break the shape down into shapes you can easily find the area of.
I found the area of the two squares on the bottom
They are identical and are both 2 units tall and two units long giving, giving an area of 4, and since there are two of them you can multiply the are by two giving you 8
Next found the area of the remaining shape which is just a rectangle that excludes the two bottom squares which is 10 units long and 5 units tall multiplying to 50
50+8=58
3. 170,000cm
4. 2,000m
5. 600mm
6. 2.38m
7. 2.4m
8. 0.175cm
The width is 12.8 and when u round it is 13 foot
Answer:
Step-by-step explanation:
Sum of all the angles of 12 sided polygon= (n -2)*180
= (12 - 2 )*180 = 10 * 180 = 1800
Four interior angle each of xº + 8 interior angles each of 2xº = 1800
4*x + 8*2x = 1800
4x + 16x = 1800
20x = 1800
x = 1800/20
x = 90°
