1h 15minutes, I converted each time into fractions, 2hours to
and the 8hour to
, this means, painter #1 finishes 1/2 of the project in 1 hour, and paither #2 finishes 1/8 of project in 1 hour, now when we make each fraction out of 2 hours, so
and
, we add them and get
, then as mixed number, 1 1/4 which is 1 hour and 15min<em>(1/4 of a hour)</em>
I believe im right.
Answer:
Step-by-step explanation:
The directrix y=-6 is parallel to the x axes, so parabola has equation of the form
where 
is the vertex of parabola and p is parabola's parameter.
By the definition, 
is the distance from the vertex to the directrix, so
Hence, the equation of parabola is
See attached diagram for the graph of parabola and its directrix.
In vertex form this equation is
9514 1404 393
Answer:
D. If a sum of two numbers is multiplied by a factor, you can multiply each number by that factor and then add the products.
Step-by-step explanation:
The point of the distributive property is that it allows multiplication to be distributed over addition. That is, ...
a(b +c) = ab +ac
The product of a factor and a sum is the same as the sum of the products of that factor with each of the elements of the sum. This is expressed in statement D.
__
Statement A refers to the commutative property of multiplication.
Statement B is a restatement of the multiplication rule in the "order of operations."
Statement C refers to the associative property of multiplication.
Statement D is a restatement of the distributive property.
