P=a+b+c. Sub in what we know: 29=a+a+(a+5). Combine like terms: 29=3a+5. Subtract 5 from both sides: 24=3a. Divide by 3: 8=a. Short sides: A=8m, b=8m, long side: c=13m. :)
Answer:
a. 20%
b. 40%
Step-by-step explanation:
a. 3km =3000m
600/3000×100=20%
b. 3200/8000×100=40%
I have the answer for the first question, the second one idk how to do. To solve mean add all the numbers and divide by how many there are. 300/5 = 60 so that is the mean. For standard deviation subtract mean from every number in the list and square it. 225, 100,0, 25, and 225. Average these numbers and you will get the standard deviation of 115. Im sorry I cant do the second question but I hope this helped for the first one.
Answer:
a. rational numbers
Step-by-step explanation:
we observe that -3/4 is a proper fraction (i.e it is a rational number)
hence
1) It cannot be a whole number
2) it cannot be an integer
therefore any answer choices that mention whole number or integer is not correct. By default, only a is correct.
