Answer:
The volume of can A is half the volume of can B.
Step-by-step explanation:
Given
Can A and Can B
Required
The true statement
For Can A, we have:
The volume is:
This gives:
For Can B, we have:
The volume is:
This gives:
So, we have:
By comparison, (d) is correct
60*(1-x)=36
60-60x=36
-60x=36-60
-60x=-24
x=24/60
x=4/10
x=2/5
x=0.4
36 is 40% less than 60
Answer:
The answer is C.
Step-by-step explanation:
Add 3 to both sides and you will get x/2=10. Multiply by the reciprocal on both sides making x=20.
Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
Answer:
to be quick divide 3/4 ×100=75 percent
1/10=10
.25×100=25
0.8=80
1/2=50 so now u know which one is the smallest from largest so it is 1/10 , 0.25 ,1/2, 3/4, 0.8
