5.2 < x < 5.5
square
5.2² < x² < 5.5²
27.04 < x² < 30.25
Pick any number for between 27.04 and 30.25 for x², as long as it's not a perfect square. So you could pick 30.
x² = 30
x = √30 → irrational number between 5.2 and 5.5
Answer:6
Step-by-step explanation:
Answer:
4.74 hours
Step-by-step explanation:
Given that both person have to place same number of rivets that is
11209
first person take 9 hours to complete the work
hence 1 hour work of 1st person is 
of total work
second person takes 10 hours to complete the same work
hence 1 hour work of 2nd person is 
Now if both work together then
1 hour work of both person = 
=
thus working together they need 
hours = 4.74 hours to complete the whole work which is placing 11209 rivets
Answer:
D
Step-by-step explanation:
Straight line (straight angle) is always 180 degrees.
The angle adjacent to 115 and 115 degree angle would sum up to 180 (straight line).
So, that angle would be:
180 - 115 = 65
Now, we know the triangle's 2 angles: 85 (given) and 65 (found), thus we can find the third angle (leftmost):
85 + 65 + third angle = 180 [sum of 3 angles in a triangle is 180]
150 + third angle = 180
third angle = 180 - 150
third angle = 30
This third angle is adjacent to w and forms a straight line, so we can write:
third angle + w = 180
30 + w = 180
w = 180 - 30
w = 150
Correct answer is D
i wish i knew but you got this
