Answer:
200/8=25
Step-by-step explanation:
the answer is 25cm^
Answer: after 6 years.
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^t
Where
A represents the value of the car after t years.
t represents the number of years.
P represents the initial value of the car.
r represents rate at which the value is decreasing.
From the information given,
P = 3000
A = < 10000
r = 16% = 16/100 = 0.16
Therefore
10000 = 30000(1 - 0.16)^ t
1000/30000 = (0.84)^t
0.333 = (0.84)^t
Taking log of both sides to base 10
Log 0.333 = log0.84^t = tlog0.84
- 0.4772 = t × - 0.0757
t = - 0.4772/ - 0.0757 = 6.3 years
2, 7.479, 8, 8.49, 9, 17, 20
Answer:
C= 15
Step-by-step explanation:
subtracting 32 from both sides
Dividing both sides by 9/ 5
Perimeter is 2L+2W so we can say 2L+2W=60
The width is 8 inches more than the length so W=L+8.
Substitute our expression for W into the equation so all the terms are the same
2L + 2(L+8)=60
2L+2L+16=60
4L+16=60
4L=44
Length=11 inches
Width= 11+8 = 19 inches
We can prove this answer is right by doing 11 + 11 + 19 + 19 which equals 60
