Answer:
l=102 feet, w=68 feet
Step-by-step explanation:
Let w=width and l=length
P=2l + 2w
And we know that w=2/3l
So, using substitution...
340=2l + 2(2/3l)
340=2l + 4/3l
340=6/3l + 4/3l
340=10/3l (now multiply both sides by 3 to get rid of fraction)
1020=10l
So l=102
Now plug in to get w
2(102)+2w=340
204+2w=340
2w=136
w=68
Now check:
2(102)+2(68)=
204+136=
340 It works!
Answer:
Given:
Sebastian :
Principal(invested)= $7,100
Rate of interest= 8.14% compounded monthly
Eva:
Principal(invested)= $7,100
Rate of interest= 8.12% compounded continuously
Step-by-step explanation:
After 5 years,
In Sebastian case:
Amount= Principal*
Amount = 7100*
Amount= 7100*
Amount=7100*109.4415
Amount= $777,034.43
In Eva case,
Amount= Principal*
Amount = 7100*
Amount= 7100*130.5818
Amount= $927,130.92
Difference between their money=$927,130.92-777034.43
=$150,096.49
Eva has $150,096 more money than Sebastian.
Answer:
that confusing
Step-by-step explanation:
Answer:
13.62 m
Step-by-step explanation:
We are to determine the value of the adjacent side given the value of the hypotenuse
we would use cos to determine this value
cos 63 = adjacent / hypotenuse
0.45399 = x / 30
x = 30 x 0.45399 = 13.62
Position vector R = < 4,0,1>
(given point)
normal vector n = < 3,-1,9>
equation:
n(r-R) = 0
3(x-4) - y + 9(z-1) = 0
