Answer:
50.05 cm^2
Step-by-step explanation:
Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.
The rectangle's size is 6.5x5.5=35.75 cm^2
The rectangle's size is 11.7-6.5 to get the base length, which is 5.2
The height is 5.5
So it's 5.2*5.5/2=14.3 cm^2
14.3+35.75=50.05 cm^2
The lowest common multiplier is 112.
14 times 8 = 112
<span>8 times 14 = 112 </span>
<span>7 times 16 = 112</span>
Answer:
y = 2
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = 
, then
sin45° = 
= 
= ( cross- multiply )
y = (
)² = 2
We have been given that the painting is 3 times as long as it is tall.The expression 
represents the perimeter of the painting, where x represents the length of the short side of the painting in feet.
To find the the amount of framing needed when short side of the painting measures 2.6 feet, we will substitute 
in our given expression.
We can simplify our expression as:
Therefore, a total of 20.8 feet of framing is needed.
Let x be the attendance in the fourth show to reach the
average they want.
So to solve:
100 + 105 + 91 + x
----------------------- > 100
4
296 + x
--------------- >
100
4
Then, multiply both sides by 4 and the result is:
296 + x > 400
X > 400 – 296
X > 104 is the number to achieve the desired attendance
average
