Answer:
Step-by-step explanation:
Simple interest = 
End of first year = 650+19.5 = $669.50
End of second year = 669.50+19.5 = $ 689
End of third year = 689+19.5 = $708.50
End of fourth year = 708.50 +19.5 = $ 728
End of fifth year = 728 +19.5 = $747.50
Answer:
I think he made a mistake in the first one
Step-by-step explanation:
Answer:
8.058655822 mins
Step-by-step explanation:
We have a table and to solve for this we might want to find the equation for this
This is a exponential function
To solve for this we need the rate of decay and the x intercept
We know the x intercept is 180 because in 0 mins the temp is 180
To solve for decay we need to know the temp of the cake after 1 min
to get the decay value we can do
125= 180 (x)^5
.69444444444 = x^5
0.929667185 = x
so the equation would be
180 (0.929667185)^x
if we tell this equation to equal 100
we get
100 = 180 (0.929667185)^x
.5556 = (0.929667185)^x
log .5556 = log 0.929667185 *x
log .5556 / log .929667185)
8.058655822= x
After 8.058655822 mins the cake will be 100 degrees
Answer:
the answer is 80 i think
Step-by-step explanation:
bc dependng on 2lw+2lh+2hw, formula 8 and 10 would be length and width
Lets say
8=width
10=lenght
3in=height
u would do
2 x l x w + 2 x l h + 2 x h x w=
2 x 10 x 8 + 2 x 10 x 3 + 3 x 8=
160 + 60 + 48+=
268 is the sa
pls brainliest and more points :0
