Answer:
1.179.17
Step-by-step explanation:
area of triangle= height*base/2=25.48
there are 4 triangles so multiply 25.48*4=101.92
Since it’s a regular octagon, all the sides are equal to = 4cm
Like shown above in the diagram, the sides of the octagon can be extended such that it forms a square.
According to Pythagorean theorem, x2 + x2 = 42; 2x2 = 16
x = √8cm
Total side length for the square= 4 + √8 + √8 = 9.657cm
Area of square= (9.657cm) 2 = 93.25cm2
Area of 4 triangles= 4 (1/2 * √8 * √8) = 16.0cm
Area of octagon, A = Area of square – Area of 4 triangles = 93.25 – 16.0 = 77.25cm2
now add 101.92+77.25=179.17
Answer:
C(n)=1.25n
Where n= number of cans
Step-by-step explanation:
C=cost
n=number of cans
Quantity Total cost
1 $1.25
2 $2.50
3 $3.75
4 $5.00
Total cost, c(n) =1.25n
Check
Total cost when n=4
Total cost c(4)=1.25×4
Total cost c(4)=5.00
Hi sorry I’m sorry I did get my message sorry to bother you’re going to be home today I’m sorry I wanna is that the way I do wanna was a good day and I’ml3553248374
Slope = (y2 - y1) / (x2 - x1)
slope = (-7-10) / (5 - (-3)
slope is supposed to be -17/8
I am guessing she made her mistake by adding a negative sign...the student did : (-7 - (-10) / (5 - (-3) = (-7 + 10) / (5 + 3) = 3/8
C.) 1600 pi cm3
When you do 10^2 you get 100 and you multiply that by the height so 16 and you get 1600.
