Step-by-step explanation:
Work:
V = 2m^3
2m^3 = (w)*(2w)*(h)
Possible dimensions:
length width height surface area
2 1 1 8 units^2
1 1/2 4 12.5 units^2
1/2 1/4 16 24 1/8 units^2
Answer:
C and E are not on the line.
Step-by-step explanation:
Just substitute for the x and the y and see which ordered pair fits and which does not:
If Left side of the equation = right side then the point fits.
A. y = -3
-2x+5 = -2(4) + 5 = -3 So A is on the line
B. y = 9
-2(-2) + 5 = 9 So this point does lie on the line.
C. y = 1
-2(3) + 5 = -1 No.
D. y = 7
-1(-1) + 5 = 7 YES.
E. y = 1
-2(1) + 5 = 3 NO.
Answer:
A = 20.5 sq units
Step-by-step explanation:
you have the height of 5 but need to figure out the base
we can use the Pythagorean Theorem two times to find it
1) a² + 5² = 7²
a² = 49-25
a = 
= 
·
= 2
2) b² + 5² = 6²
b² = 36-25
b = 
Base = 2 +
A = 1/2 x 5· (2 + )
A = 2.5 · (2 + )
A = 2.5(8.2)
A = 20.5
Answer:
about 6.6 years
Step-by-step explanation:
41,500=14,000*.45*x
41,500=6,300*x
41,000/6,300=x
6.5873=x
6.6=x
