<span>For the answer to this question,
Let x = depth of the gutter
then
18 - 2x = width of the gutter
Cross section area
A = depth x width
</span><span> = x(18 - 2x)
A = 18x - 2x^2
:
Axis of symmetry will give x value for max area:
x = -b/(2a)
x = -18/(2x(-2))
x = 4.5 inches is the depth for max area
</span><span>Max area: 4.5 * 9 = 40.5 sq/in
I hope my answer helped you.</span>
So 1/9-16z^2 this is a diffirence of two perfect squares thing
so (1/3)^2-(4z)^2
so ((1/3)-4z)((1/3)+4z)
Ab + bc = ba + bc = b( a + c )
The equation that best represents the relationship between
the number of loaves of bread which is denoted by b and the number of cups of
bananas which is denoted by c is c = 2 1/4b.
We know that we need 11 ¼ cups of bananas is needed to make
5 loaves of bread.
We need to divide 11 ¼ to 5 which the answer is 2 ¼. The 2 ¼
represents how many cups is needed to make 1 loaf of bread.
For this case we have the following definition:
tens place: number of two digits whose absolute value is greater than zero.
Then, we have the following rounding rule:
If the previous number is greater than or equal to five, the next number increases by one unit.
We then have the following numbers rounded to 30 when rounded to the nearest ten:
26: twenty-six
27: twenty-seven
Answer:
two different numbers that round to 30 when rounded to the nearest ten are:
26: twenty-six
27: twenty-seven
