David is paid £34000 per year. He is going to get a 3% increase in the amount of money he is paid. Work out how much money David will be paid per year after the increase. :)

His new sallary will be 35020.

Step-by-step explanation:

Since David is paid 34000 and will recieve a raise of 3% his new sallary will be the sum of the previous one and the raised amount. Since his previous sallary is the amount to wich the calculus is based we will consider it to be 100%, so his new sallary will be 103% of his previous one. To calculate that we can use a rule of three in such a way that 34000 is to 100% as x is to 103%. So we have:

34000 -> 100%

x -> 103%

x = (34000*103)/100 = 35020

His new sallary will be 35020.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
