I believe the measure of AB is 90 degrees, but I may be wrong.
A = bh/2
A = 2.4 x 3 / 2
A = 7.2 / 2
A = 3.6 m²
They will need 4 bags of pebbles.
First you turn 20% into a decimal by dividing by 100 and you get .20
then you multiply .20 by 160 and get 32
then subtract:
160-32=128
So if you have 120 bananas and you have a 20% decrease then you would have 128 left over
Hope this helped!! :D
Answer:
0.9545
Step-by-step explanation:
Let an integer be x.
If x is increased by 15%, then the value of the number would be
115/100x=1.15x
If 1.15x is decreased by 17%, then the value of the number would be:
(100-17)/100×1.15x
83/100×1.15x=0.9545x
