Step-by-step explanation:
3 times n
As you can see, the area of the scarf is equal to the area of the rectangle minus the area of the 2 semi-circles (which form a circle)
Now, we calculate the area of the rectangle : 28 x 15 = 420 in2
The diameter of the circle is 15in -> The radius = 15 : 2 = 7.5in.
We now find the area of the 2 semi-circles : 7.5 x 7.5 x 3.14 = 176.625 in2
So, the area of the scarf is : 420 - 176.625 = 243.375 in2
#7 is 0.04 and it is a terminating decimal
Answer:
x = 14
BE = 6
Step-by-step explanation:
to find 'x': BG = 1/2[(x-9) + (3x-13)]
BG = 4x-22 / 2
BG = 3x-25
3x-25 / 1 = 4x-22 / 2
cross-multiply:
4x-22 = 2(3x-25)
4x-22 = 6x-50
-2x = -28
x = 14
to find 'BE': CB = BE
2x+4 = 7x-1
-5x = -5
x = 1
BE = 7(1) - 1
BE = 6
We set up a proportion: ?/42,000= 3/5
Cross multiply:
5*?= 3*42,000
⇒ ?= 3*42,000/5= 25,200
3/5 of 42,000 is 25,200~
