Answer:
A - 25%
B - 100%
C - 75%
Step-by-step explanation:
I'm pretty sure. Hope this helps. If the shape is divided into 4 equal parts, each one would be worth 25%.
1 time=2mins
xtimes=30mins
30/2 ×1= 15.
Therefore it can be completed 15 times in 30mins
Answer:
B. 15
Step-by-step explanation:
Prime factors of 15 is 3 and 5
sum of 3 and 5 is 8
If you factor the equation you can see what the solutions are. Two factor a quadratic of the form ax^2+bx+c, find two values which satisfy two conditions...
jk=ac=-15 and j+k=b=-2 so j and k must be -5 and 3 so the factors are:
(x-5)(x+3)
So the other solution is x=5
