Answer:
It will take the apprentice 24 days working alone
Step-by-step explanation:
Let the number of days it takes the apprentice be x
It will take the landscaper x/3 ( since he is three times faster)
The rate for both will be 60/6 = 10 sq m per day
Rate for apprentice is 60/x
rate for the boss is 60/x/3 = 180/x
Adding the rates together;
60/x + 180/x = 10
240/x = 10
240 = 10x
x = 240/10
x = 24 days
So first subtract 20 from both sides of the equation.
3x-4=35
now add 4 to both sides.
3x=39
now divide both sides by
x=13
Answer:
(-2,0)
Step-by-step explanation:
remember the rule for 90 degree clockwise is (-y,x) opposite y and x
the negative in there DOES NOT mean it will always be negative it means opposite but in this case yes it's negative because the opposite of positive is negative
Hope this helps dude, I'm also learning this in online school lol. ^-^
A)she is not right.because if the remaining peice is the hypotenuse of the triangle, the answer will be around 27.8 if the hypotenuse is 22 then the missing angle is 13.96
b)yes it will work
if you double the measurements of the two sides of a right triangle the other one will be double, too(you can get help from Pythagoras theorem )
c)yes it is possible. if we can double the sides of a right triangle it means that we add measurements to the triangle.
for example:a triangle with sides of 3,4,5
if we add 6,8,10
it will be 9,12,15
hope I could help
