Answer:
ans: ii) 87° and iii) 60°
Step-by-step explanation:
ii)
y° = 180° - ( 56° + 37°)
missing angle on triangle is alternate angle of y° so are equal and sum of angles of triangle is 180°
iii)
x° + 2x° = 180°
sum of co interior angles is 180°
Working together three workers would take 1 hour 36 minutes to finish the job
<em><u>Solution:</u></em>
Given that first worker can finish the job in 8 hours
So in one hour, first worker can do 
th of the work
The second worker can finish the job in 4 hours
So in one hour, second worker can do 
th of the work
The third worker can also finish the job in 4 hours
So in one hour, third worker can do th of the work
<em><u>The three workers working together in 1 hour can do:</u></em>
The three worker can thus do 
th of the work in one hour
Hence the three of them together can finish the work in 
hours
hours
Thus working together three workers would take 1 hour 36 minutes to finish the job
Answer:
it is y=0.25
Step-by-step explanation:
because Step 1: Simplify both sides of the equation.
3.2y−1.4y+y−0.6y=0.55
3.2y+−1.4y+y+−0.6y=0.55
(3.2y+−1.4y+y+−0.6y)=0.55(Combine Like Terms)
2.2y=0.55
2.2y=0.55
Step 2: Divide both sides by 2.2.
2.2y
2.2
=
0.55
2.2
To do this we need to rewrite the equation in terms of y
4y=12-3x
y=3-3x/4
Therefore the gradient is -3/4
Answer:
(11/15)'s
Step-by-step explanation:
(2/5) is equal to (6/15)
(1/3) is equal to (5/15)
(5/15)+(6/15)=(11/15)
