If Nate paints the wall in 4 hours, it means that he can paint 1/4 of the wall every hour.
Similarly, if Jill paints the wall in 7 hours, it means that he can paint 1/7 of the wall in one hour.
So, together, they paint the following fraction of the wall in one hour:
.
At this rate, they need 28/11 hours to paint the whole wall, in fact, after that amount of time they paint
i.e. the whole wall
Answer:
3, 4, 5.
Step-by-step explanation:
there are basic families of the right angled triangles and the one above is one of them.
some include;
7, 24, 25.
6, 8, 10. etc
We know that
in a quadratic equation of the form
ax²+bx+c=0
the discriminant is
D=b²-4ac
if D> 0 <span>then there are two real number solutions
if D=0 </span><span>then there's only one real number solution.
if D< 0 </span><span>then there are two complex number solutions
in this problem
we have
</span>3x²<span>-6x+3=0
a=3
b=-6
c=3
so
</span>D=b²-4ac-----> D=(-6)²-4*(3*3)----->D=36-36------->D=0
therefore
there's only one real number solution
Answer:
The equation is either n-6^3 (this is without cubing the 6, this is probably what your teacher is looking for.) or n-216 (this is what the equation looks like when 6 is cubed)
Answer:
1/3(3y^2+2y-15).that's the highest answer. I can do
