Where is the passage so i can help you
0.50 because the 8 is in the hundredth place and is greater than 5 so you round it up. Then you turn that to a zero because the 8 becomes a 10 but you only use the zero. Then you turn the 4 to a 5 or else the number would be getting smaller and not larger.
55% of 40 is 22
Change the percentage into a decimal by dividing it over 100:
55/100 = 0.55
Divide:
22/0.55 = 40
Answer:
The base is 10cm. The other two sides are 20cm each
Step-by-step explanation:
I believe that "the base is twice shorter" means that the two equal sides of the iscosceles triangle are twice the length of the base.
Using the equation x + 2x +2x = 50 where x is the length of the base, we can simplify it to
5x=50. Then divide both sides by 5 to get the results:
x=10 for the base and
2x=20 for the other two sides.
