Answer:
B.
Step-by-step explanation:
The problem is saying 2/5 squared by -2 times -3 multiplied by itself 4 times.
2/5 multiplied by itself -2 times looks like this: -2/5 times -2/5.
-3 multiplied by itself 4 times looks like this: -3 times -3 times -3 times -3.
Put the two together and it looks like B.
Answer:
-0.45, 2/5, 54%
Step-by-step explanation:
54%=54/100
=87/50
2/5=20/50
-0.45 must be the smallest as it is negative
3/30=9/v
3×3=9
30×3= 90
v=90
New length = 30x110% = 33cm
new width = 20x105% = 21cm
original perimeter = 30x2 + 20x2
= 60 + 40 = 100
new perimeter = 33x2 + 21x2
= 66 + 42 = 108
increase in perimeter = 108-100 = 8
percentage increase = 8/100 x 100% = 8%
Answer:
Angle 1: 105
Angle 2: 75
Step-by-step explanation:
You know 2 is 75 because both lines are parallel.
To get 1 you subtract 75 from 180.
