Answer:
7.5
Step-by-step explanation:
It is longer than 5, so cross 2.5 and 5 out, 10 is too big, so 7.5 is the correct answer
Answer:
12.3 feet.
Step-by-step explanation:
As we are given that 
is an right angled triangle.
And we have to find out the value of side OP to the nearest tenth of a foot by rounding off the value as seen in the attached figure as well.
By using Trigonometric functions in a right angled 
, we know that:
Here, 
is 
, Perpendicular is side <em>OP</em> and Base is side <em>PN</em>.
So, 
Putting the values of <em>PN </em>and 
.
Hence, the value of <em>OP </em>is 
.
Answer:
3
Step-by-step explanation:
-16 + 3n = -(8 + 5n)
The - sign outside the parentheses acts as a -1, and so it is distributed to each term in the parentheses.
-16 + 3n = -8 - 5n
+16
3n = 8 - 5n
+5n
8n = 8
/8
n = 1
The sum of length and width is half the perimeter, so is (70 in)/2 = 35 in. Since this is the sum of length and width, if we add 5 inches, it will be twice the length. That is ...
... length + width = 35 in
... length + (width + 5 in) = (35 in) + (5 in)
... 2×length = (35 in) + (5 in) = 40 in
The length of the rectangle is 20 inches.
