Step-by-step explanation:
12 marbles, 2 yellow
12/2= 6
1/6
Answer:
Step-by-step explanation:
65.97in
Change the function into vertex form:
f(x)=x²-10x+16
make a square by (adding half of -10)², which is 25, then subtract it:
f(x)=x²-10x+25-25+16
f(x)=(x-5)²-9
so the vertex is at (5,-9)
another way to do it:
f(x)=x²-10x+16
the vertex is when x=-

, b=-10, a=1 in this case.
x=-(-10/2*1)=5
plug x=5 into the quadratic function, you get f(x)=-9
Answer:
350 sq ft
Step-by-step explanation:
Given that:
840 sq ft area has a bedroom, kitchen and bathroom.
Let the area of bedroom be
sq ft.
Then the area of kitchen will also be
sq ft.
Let the area of bathroom be
sq ft.
As per question statement:

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.
i.e.

Subtracting equation (1) from (2):
i.e. (2) - (1):
sq ft
Putting the value of
in (1):

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>
