Answer:
0
Step-by-step explanation:
-7=2x-7
+7 +7
0=2x
x=0
What you want to do is make a common denominator (the bottom number)
So does 3 go into 12? Yes it does (3 x 4)
So since you times the 3 by 4 you have to times the 2 by 4 aswell (so that it stays the same number just on a diffrent scale) the 2/3 becomes 8/12 (which is also 2 thirds) so you do 7/12 + 8/12 (7 twelths plus 8 twelths) which becomes 15/12 (15 - 12 = 3
So it comes 1 3/12 or 1 1/4)
Answer:
55.4 ft²
Step-by-step explanation:
The special triangle with angles 30°-60°-90° has side lengths in the ratios ...
1 : √3 : 2
The area of the triangle can be found using the area formula ...
A = 1/2bh
where b is the base and h is the perpendicular height.
__
<h3>sides</h3>
The longest side is given as 16 ft. This corresponds to "2" in the ratio, so the other two sides have lengths ...
8 ft, 8√3 ft
__
<h3>area</h3>
These area the perpendicular sides of the triangle so, work well to find the area.
A = 1/2bh
A = 1/2(8√3 ft)(8 ft) = 32√3 ft²
A ≈ 55.4 ft²
The area of the triangle is about 55.4 square feet.
