For clarity, let me make a few small corrections:
<span>Mrs. Hill purchased four new coffee urns at $1.69 each. For buying in quantity she is given a 3 1/2 percent discount on the bill. What is the amount she paid?
</span>
$1.69/urn is the unit price (the price for ONE urn). Multiply that by 4 urns. Note that urn and urn will cancel out, and you'll be left with an expression with a $ sign.
Next, multiply that result by 0.035 (which is the decimal equivalent of 3 1/2%).
Answer:
88cm^3
Step-by-step explanation:
The volume of a pyramid is the base times height divided by 3. First, we can find the area of the base. We have a right triangle with a base of 8 and a height of 6. The area of a triangle is the base times height divided by 2. This gives us:
8 * 6 ÷ 2 = 24cm^2
We can see that 11cm is the height as it is perpendicular to the base. We can set up an expression from the formula mentioned at the beginning:
11 * 24 ÷ 3 = 88cm^3
It’s two because each one is two away from each other like 50-52
