Answer:
60+2x≥300
Step-by-step explanation:
So we know that she makes a base of $60 a week and gets $2 extra for every item she sells. First, we set up an equation for how many items she would have to sell to make exactly $300 in a week. 60+2x=300. Now, all we do is replace the equal sign with a ≥ sign because it says at least which means more than or equal to.
If 3 =
, then we know 9 =
because 9 is 3 squared.
can be simplified to
So now we know
=
·
Since
and
have the same base, we can express it as a single term by adding the exponents together.

Answer:
Step-by-step explanation:
Solve the brackets first.
Division comes next.
Cancel the negative signs.
Multiply the terms.
We know that the volume of a sphere is:
V
=

where
r
=

ft
is the radius;
we need half of this, so we use:
