Answer:
y = 400(1.01)^t
Step-by-step explanation:
Firstly find the rate
(Take any balance for two years, e. g 400 and 404,412.12 and 416.24,etc to get simple interest)
408.04-404= 4.04
I=(P*R*T)/100
From which R=(100*I)/PT
R= 100*4.04/404*1
R=1%
Using compound interest formula
A =P(1+r/100)^n
where n is time
substituting each value
y = 400(1+1/100)^t
y= 400(1.01)^t
4/(m+9)+5/(m^2-81)=
4/ ( m+9) +5 / ( m-9)(m+9)=
4(m-9)/(m+9)(m-9)+ 5 / (m+9)(m-9)=
(4m-36+5)/(m+9)(m-9)=
4m-31/ (m+9)(m-9)
the answer is D
37 = 2/3x - 1
37 + 1 = 2/3x
38 = 2/3x
38 / (2/3) = x
38 * 3/2 = x
114/2 = x
57 = x <=== when complete, the highway will be 57 miles
Answer:
4 yellow rosebushes
Step-by-step explanation:
Givens(What the question tells us):
m = 3(There are 3 multicolored bushes)
r + y + p = 15 - m( total red bushes plus total yellow bushes plus total pink bushes equals 15 - the amount of multicolored bushes)
r = y = p (total red bushes equals total yellow bushes which also equals total pink bushes)
Since we know m =3 we can substitute m for 3 in the second equation:
r + y + p = 15 - 3.
r + y + p = 12
Now since r, y, and p are equal we can divide the total amount left (12) by the 3 kinds of roses left to get our answer:
12/ 3 = 4 red, 4 yellow, and 4 pink
Since we are solving for the amount of yellow the answer is:
4 yellow rosebushes
