Use a calculator to find that
7.095*2.55 = 18.09225
Then round to the nearest tenth to get 18.1
Why the nearest tenth? Because we want the answer to have 3 sig figs. This is the smallest number of sig figs between the two original numbers (7.095 and 2.55).
Answer: Choice D) 18.1
Answer:
1st answer
Step-by-step explanation:
From pythagorus theorem.
Since hypotenuse
Just subtract and then add then you should get your answer.
Answer:
27
Step-by-step explanation:
Given that the total number of people protesting is 81. These people are either male - Student or non student or Females (student or non students)
Given that there are 36 males then number of females
= 81 - 36
= 45
If there are 18 females non students then the number of females protesting that are students
= 45 - 18
= 27
To find invers
1. solve for y
2. replace y with xinverse
so
x=4-4y+y^2
reorder right side
x=y^2-4y+4
factor right side
x=(y-2)^2
squaer root both sides
+/-√x=y-2
add 2 to both sides
2+/-√x=y
switch x and y
2+/-√y=xinverse
xinverse=2+√y or 2-√y
subtract 4 from both sides
