Take the price of pears (£1.30 per kilogram) and multiply it by the amount of pears (7kg). You get 9.1 so now you take the total amount spent (£12.70) and subtract the 9.1 and you get 3.6 now that is the amount you spent on the apples. So take 3.6 and divide it by the amount of apples you got (2kg) you will get 1.8 and that is your overall answer.
The amount after 7 years is given by:

The answer is: $20,948.15
46.06 would be the answer
Answer:
112.81 m.
Step-by-step explanation:
The pole and the tower and their shadows form 2 similar triangles so their corresponding sides are in the smae ratio.
Therefore we have the relation:
1.21 / 48.75 = 2.8 / x where x is the height of the tower.
Cross multiplying:
x = 2.8 * 48.75 / 1.21
= 112.81 m
First of all, try to understand the questions then try to make a pair of linear equations. After that make the coefficients of x or y equal in both RFD equations by multiplying them by suitable values then add or subtract them ,in such a way which will terminate any one of the variables. Then find the value of left variable. After that just put the value you have found just now In any of the equations and you'll really get the value of the second variable too.
