Answer:
2,242.5
Step-by-step explanation:
10² = 100 (one and 2 zeros ; notice that the exponent is 2 )
Makes sense that we will need a bigger number than 22.425 to divide by 100 to get a 22.425 so move the decimal point to the left 2 spots and get 2,242.5.
2,242.5 /100 = 22.425
Answer:
16 pieces
Step-by-step explanation:
The total length of ribbon cut off from the 20 pieces is 8*20 because each piece is equal to 8. 8*20=160
The amount of ribbon left afterwards is 400-160 which is equal to 240.
We can do 240 divided by 15 to see how many pieces that we can cut. 240/15=16
Answer:
x < -6

Answer:
B) 2\ sq.rt{3}units
Step-by-step explanation:
using Pythagoras theorem
a^2+ b^2=c^2
a^2+ 3^2=(√21)^2
a^2+9= 21
a^2=21-9
a^2=12
a=√12
a=2√3
