The answer is 54 degrees I took the exam I got it right
$42.
13/2 = 6.5, 25/4 = 6.25, 42/7 = 6.
Answer:
Step-by-step explanation:
let's break down 2,000,000 into its multiples,
Multiples of 2,000,000= 2⁷ × 5⁶
Using above values to find different combinations of length(l) and breadth (b) of rectangle and corresponding parameter of rectangle
- l=5, b=400,000 ,parameter= 2(5) + 2(400,000)= 800,010, total length of fence required= parameter+ side with shortest length= 800,015
- l=2 b=1,000,000 parameter= 2,000,004, shortest fence required= 2,000,008
- l=4, b= 500,000 parameter= 1,000,008, shortest fence required= 1,000,012
- From above, we can see a trend that the parameter of rectangle decreases if length and breadth are increased provided that area is constant. So, a rectangle will have shortest parameter if all of its sides are equal.
- length of side of rectangle with shortest possible parameter= 2^3 ×5^3= 1000 and breadth of side of rectangle with shortest possible parameter= 2^4× 5^3=2000
- Shortest possible length of fence= 2(2000)+2(1000)+1000=7000ft
Answer:
B) 1,2
Step-by-step explanation:
Answer:
21). WX = 10
22). VW = 22
23). WY = 20
24). VX = 32
25). WZ = 30
26). VY = 42
Step-by-step explanation:
In the figure attached,
V, W, X, Y and Z are collinear.
VZ = 52, XZ = 20 and WX = XY = YZ
21). Since XZ = 20
XY + YZ = 20
WX + WX = 20 [Since, XY = WX = YZ]
2(WX) = 20
WX = 10
22). VZ = VW + WX + XY + YZ = 52
VW + 3(YZ) = 52 [Since, WX = XY = YZ]
VW +
= 52
VW +
= 52
VW = 52 - 30 = 22
23). WY = WX + XY
= 2(WX)
= 20
24). VX = VW + WX
= 22 + 10
= 32
25). WZ = 3(WX)
= 30
26). VY = VZ - YZ
= 52 - 10
= 42
