<span>if its 3 times (6/8 − 1/2) + 0.25 then this equals 1
if its </span><span>3x(6/8 − 1/2) + 0.25 then its 3/4x+1/4</span>
Alright, so you know that the formula for the area of a triangle is a=bh/2
First start out by identifying your base and height.
Base is the side that the shape is "standing on", in this case, that would be 9cm.
Now, the height is the measurement that is perpendicular (90 degrees to the base), which in this case is 12 cm.
Now, plug these values into your formula
(12)(9) /2 = 54 cm squared! hope this helps :)
Answer:
12n+9=93
solve for n
12n=93-9
n=84/12
n=7
therefore, Mr. copper bought 7 tickets.
Answer:
44%
Step-by-step explanation:
the area of a rectangle = Length × Breadth
original area of james pit = 20×20=400in²
new size = 20 + 4 =24 inches
new area = 24 × 24= 576in²
increase in area = 576 - 400 = 176
percentage increase = 
× 100
=
× 100
=0.44 × 100
=44%
percentage increase in area is 44%
