Answer:
the answer is third one.......
Answer:
46 units
Step-by-step explanation:
The diagonals of a rectangle bisect each other, which means that in this case, AE = EC. So, set the two expressions equal to each other and solve for x:
6x - 55 = 3x - 16
3x = 39
x = 13
Now, another property of rectangle diagonals is that they're the same length, which means AC = DB. So, let's just find the length of AC:
AC = AE + EC = (6 * 13 - 55) + (3 * 13 - 16) = 23 + 23 = 46
Thus, since AC = DB, we know that DB = 46 units.
Hope this helps!
Answer:
Length = 12 feet, Width = 10 feet
Step-by-step explanation:
Let the length of the bedroom be 'x' ft and the width of the bedroom be 'y' ft.
We know that the perimeter of a rectangle is given by,
P=2(length+width)
P=2(x+y)
It is given that, the length of the bedroom is 2 more than the width, so,
x=y+2
Putting the values in the equation of perimeter we get,
44=2((y+2)+y)
44=2(2y+2)
44/2 =2y+2
22=2y+2
2y=22−2
y= 20/2 =10
Therefore, x=y+2=10+2=12
Hence, the length of the bedroom is 12 feet and the width of the bedroom is 10 feet.
Answer:
A negative correlation between the temperature and the amount of snow still on the ground.
A negative correlation between the number of digital photos uploaded to a website and the amount of storage space that is left.
Step-by-step explanation:
These are the two relationships that are most likely to be causal. Causal relationships are those in which one aspect is the cause of the second one being described. Moreover, a negative correlation is one in which one aspect of the relationship increases while the other one decreases. In the first example, as the temperature goes up, this causes the amount of snow on the ground to go down. In the second example, as you upload more pictures to a website, there is less storage space.
