So far i have determined the following equations from the my force body diagrams. T(cos(31)) - mg(sin(25)) = 0 N - (mg(cos(25)) + (T(sin(31))) = 0 to solve for tension you rearrange the first equation to get T(cos(31)) = mg(sin(25)) so if you solve for the horizontal component of gravity you will be able to determine the tension of the string. i have tried my following answer (which comes out to 1426N) but i am incorrect. if anyone can please point out what i am missing i would be really appreciate it.

lena works for 34 hours from monday to friday at her normal rate of pay ,on saturdays she gets an overtime rate of pay ,the over
kifflom [539]

Answer: £ 8

Step-by-step explanation:

Total hours Lena works from Monday to Friday = 34 hours

Hours she works on Saturdays = 4

Overtime rate of Saturday = 1.5 times her normal rate

Let x be the normal rate.

Then , Her total earning = 34 x + 4 \times(1.5x) =34x+6x=40x

Since her total earnings for week = £ 320

So,

320=40x\\\\\Rightarrow\ x=\dfrac{320}{40}\\\\\Rightarrow\ x=8

Thus, her normal rate of pay per hour = £ 8

O<br> What is the exact circumference of the circle?<br> 3.14<br> 4<br> 7<br> pi
kow [346]
The answer is 4pi because the formula to find the circumference is C = 2 pi r. this question is asking for the terms of pi which means you remove the pi from the formula and solve it with out it. the radius is 2 because of the 2 units on the graph is halfway of the circle. you would just multiply 2 x 2 and get 4. after that you put the pi on the end of the 4. so the answer is C. (4pi)
