If prices increase at a monthly rate of 2.7 by what do they increase in a year

guapka [62]

Answer:

37.67%

Step-by-step explanation:

Suppose initially a price of $ 100

Increasing per month at a rate of 2.7%. Which is equal to 0.027

Now applying the formula:

Vf = Vi * (1 + m) ^ n

where Vf is the final quantity, Vi is the initial value, m is the rate and n is the number of months.

We know that 1 year, is 12 months, since the rate is monthly means, n = 12, we replace:

Vf = 100 * (1 + 0.027) ^ 12

Vf = 137.67

It means price increase in 1 year = 137.67 - 100 = 37.67

Which means that n a year increases to 37.67%

Answer:

Step-by-step explanation:

Given, 

Sides of the triangle = (5k-7) cm, (k-4) cm and (3m - 9) cm

Therefore, 

Perimeter of the triangle in cm = (5k -7) cm + (k-4) cm + (3m - 9) cm

= 5k - 7 + k - 4 + 3m - 9

= 5k + k -7 - 4 - 9 + 3m

= 6k -20 + 3m

= - 20 + 3m + 6k

Hence,

-20 + 3m + 6k is the perimeter of the triangle in cm.
