S is stocks and b is bonds
s + b = 28800
3b = 5s or s = 3/5 b
substitute in for s
3/5 b + b = 28800
3b + 5b = 144000
8b = 144000
b = 18000 amt in bonds
s + 18000 = 28800
s = 10800 amt in stocks
3751×2=7502
15002÷2=7502
250+7252=7502
7502+0=7502
This is the concept of algebra; given that the height of the house at time t is given by:
h(t)=<span> 400 − 39t − 157e−t/4
the velocity of the house is given by:
dh/dt
velocity of our object is:
dh/dt=-39+1/4*157e^-(t/4)
=-39+157/4 e^(-t/4)
thus the velocity at h=0 will be as follows:
at h=0, the value of t will be:
0=400-39t-157e^(-t/4)
solving for t we get:
t=-5.4 or t=10.1
since we don't have negative time, t=10.1
thus the velocity at this point will be:
dh/dt=-38+1/4*157e^(-10.1/4)
=-38.86 sec
this means that the object dropped by a velocity of 38.86 sec</span>
46 hours after 9:30 p.m. on Friday will be J. 7:30 p.m. Sunday.
Since 46 hours is almost two days, you just need to take away those two hours, and you will get the time you need, two days after the original day.
Answer:
10,000
Step-by-step explanation:
We can find the area of the floor in cm^2 and divide by the are of 1 tile in cm^2.
1 m = 100 cm
10 m = 1000 cm
40 m = 4000 cm
area of floor = LW = 1000 cm * 4000 cm = 4,000,000 cm^2
area of tile = s^2 = (20 cm)^2 = 400 cm^2
number of tiles = 4,000,000/400 = 10,000
Answer: 10,000 tiles
