Answer:
21-ounce size: $3.89
Explanation:
To compare the cost, you can calculate the cost per ounce of cereal. This means you will have to divide the cost by the total number of ounces. The cereal that costs the least per ounce will be the best buy.
$4.79 / 18oz = $0.27/oz
$3.89 / 21oz = $0.19/oz
$6.49 / 32oz = $0.20/oz
The 21-ounce size is has the cheapest price per ounce, so this is your best buy.
We have that
(w^5*z^2)*(-9*w^2*z^<span><span>5)</span>
</span><span>Multiplying exponential expressions
we know that
</span>w^5<span> multiplied by </span>w^<span>2 = w</span>^<span>(5 + 2) = w</span>^7
and
z^2<span> multiplied by </span>z^<span>5 = z</span>^<span>(2 + 5) = z</span>^7
therefore
(w^5*z^2)*(-9*w^2*z^5) =-9*( w^7)*( z^7)
-9*( w^7)*( z^7)=-(3^2)*( w^7)*( z^7)
the answer is
-(3^2)*( w^7)*( z^7
Answer:
x - ($32 + $15); or x - $32 + $15
Step-by-step explanation:
Spending on the purse and a CD means less cash then the starting amount, x.
A cone that is sliced through the vertex would make the shape of a triangle.
You are told the h eight is 10 cm and the radius is 4 cm.
The radius would be half the base, so the base would be 4 * 2 =8 cm.
The area of the triangle is found by multiplying the base by the height, then dividing by two.
Area = 8 x 10 = 80
80 / 2 = 40 square centimeters.
