It is 65.97cm^2
So I think it is option B) 21 pi = 65.97
V=pi(3^2)7/3
Step-by-step explanation:
<span>y^2-12y+36 = (y - 6)^2
or
= (y - 6)(y - 6)

Triangle ABC is an equilateral triangle. it is equiangular. Therefore, the value of x is 60 degrees.
<h3>What is an equilateral triangle?</h3>
An equilateral triangle is a triangle that has all it sides and angles equal to each other.
An equilateral triangle is equiangular.
Therefore, the angles of an equilateral triangles are equal to 60 degree each.
Recall the sum of an angle of a triangle is 180 degrees.
Therefore, the value of angle x is 60 degrees.

Please see the answers below:
Step-by-step explanation:

<em>Cost of the Calculator = $65
</em>
<em>Sales Tax added = 6%
</em>
Total Price = t = Cost of the Calculator + (Sales Tax Added x Cost of Calculator)
t = $65 + (0.06 x $65)
t = $65 + $3.90
Total Price = t = 68.90

a. When there is a sale it means that there is a discount the products offered by store. Here store is offering sale on everything with 10% off, it means that the store is offering a discount of 10% on everything. We can calculate discount price by multiplying the percent discount by the original price, then subtract the result from original price. The new price is the sale price. We will have the equation:
s = r - 0.10r
s = 0.9r
b. A proportional relationship is one in which two quantities vary directly with each other. We say the variable s varies directly as r if:
s = 0.9r
So, yes there is a proportional relationship as the sale price s is proportional to the regular price r purchased at a constant discount rate 0.9.

<em>Cost Price = $40
</em>
<em>Mark up % = 25% = 0.25
</em>
<em>Sale Price = s = ?
</em>
Sale Price = Cost Price + Markup
s = Cost + (Mark up % x Cost)
s = $40 + (0.25 x $40)
s = $40 + $10
s = $50
