Answer:
The question is incomplete or there are details missing.
Step-by-step explanation:
From similar parameters, if by what they mean is that the football field measures 300feet in length, which is the dimension in length, this can also be in terms of metre.
The conversion factor between ft and metre is 1ft = 0.3048m
As such, we can only have variations or the length of the field measured may have ranges of measurement, but as it is the length of the field can not be expressed in terms of miles, the most reasonable vale of n we can get will be the least measurement in metres.
Answer:
There were 423 adult tickets sold.
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 65 = the number of student tickets sold
x + x + 65 = 715
2x = 715
x = 357.5
x + 65 = 422.5 (round up)
Answer:
780 cubic inches
Step-by-step explanation:
Step one:
Given data
The bottom surface of the box has an area of 65 square inches.
Already given an area and a height of 12 in
we proceed to find the volume by multiplying Area and height
Required
The volume of the box
Volume= Area* height
Step two:
Volume= 65*12
Volume = 780 cubic inches
Assuming that CB is tangent, this is just a right triangle with a hypotenuse of 20 and a side of 12 so by the Pythagorean Theorem:
20^2=12^2+x^2
400=144+x^2
x^2=400-144
x^2=256
x=16
When you have this type of problem, you need to combine the like-terms and isolate the variable.
3x + 122 = 22x - 11
Add 11 to both sides to get rid of it
3x + 122 + 11 = 22x - 11 + 11 (-11 + 11=0)
3x + 133 = 22x
Then you would bring the 3x to the other side, so subtract 3x from both sides
3x + 133 = 22x
-3x -3x
133 = 22x - 3x
133 = 19x
Then divide both sides by 19 to isolate x
133/19 = 19x/19
133/19 = 7, so x = 7
Hope this helps!!
