Answer = Red portion
Firstly, find out the area of the red portion (the area around the centre).
The three figures around the centre are trapeziums, so use the trapezium area equation.
a + b / 2 x h
4.5 + 5 = 9.5
9.5 / 2 = 4.75
4.75 x 1.5 = 7.125
As there are three trapeziums, times the area by 3.
7.125 x 3 = 21.375
Area of red portion = 21.375

Next, find out the area of the blue portion.
As the blue portion is in the centre and the figure at the centre is an equilateral triangle, use the equilateral triangle area equation.
root 3 / 4 x a^2
root 3 / 4 x 5^2 = 10.83 (rounded to 2 d.p)
—
Area of red portion = 21.375
Area of blue portion = 10.83
This means that the red portion has a greater area.
Hope this helps :)
It should be 20. I hope this helps!!
There are several information's already given in the question. Based on those information's the answer can be easily arrived at. Let us first write down the details given.
Cost of a box of 10 wings = $7.00
Cost of a tray of nachos = $4.00
Amount that Freddy can spend is less that $40.
Then the equation will be
7x + 4y < 40
I hope the procedure is clear enough for you to understand.
If its rounded to nearest hundredth its 14.29%, and if rounded to nearest tenth its 14.3%
Answer:
3x²+(-27x) +0
Step-by-step explanation:
The given expression is :
x + 3x² – 28x
We need to solve this in the form of ax²+bx+c.
we can write the given expression as :
3x²-28x+x = 3x²-27x
= 3x²+(-27x) +0
If we compare the given expression with the general expression, we find that,
a = 3, b = -27 and c = 0
Hence, the required equation is 3x²+(-27x) +0.
