Answer:

if solving for m it is m= n+58/30

if solving for n it is n= 30m-58

Step-by-step explanation:

for m- divide both sides by 30 but keep it in fraction form for n+58

for n- subtract 58 from both sides to make it n=30m-58

If PQR is a triangle,given that /PQ\=15m, /QR\=17m and /RP\=18m.Find the area of the triangle to the nearest whole number.

Answer:

118.3 m²

Step-by-step explanation:

Step 1. Calculate the semiperimeter (s).

s = (p + q + r)/2

s = (17 + 18+ 15)/2

s = 50/2

s = 25 m

===============

Step 2. Calculate the area (A).

Use Heron’s formula:

$A = \sqrt{s(s-p)(s-q)(s-r)}$

$A = \sqrt{25(25-17)(25-18)(25-15)}$

$A = \sqrt{25\times8\times7\times10}$

$A = \sqrt{14 000}$

$A = 20\sqrt{35}$

A = 118.3 m²

Divide the total amount charged by the number of hours worked, and you have $/hour
