The queen size mattress has a catalog price of 428.99 dollars.
NOw, it has a trade discount rate or 20%
=> 20% / 100% = .20
Next is to do the solution:
=> 428.99 * .20 = 85.798 dollars or 85.80
Now, let's find out the net price:
=> 428.99 - 85.80 = 343.19 dollars or 343.2.
The distance between those two points is 41 and in decimal form to the nearest tenth, that's 6.4
Explanation:
Use the distance formula: √(x2 - x1)² + (y2 - y1)²
Then we plug in our x's and y's:
√(4 - (-1))² + ((-1) - 3)²
Then you simplify:
√(5)² + (-4)² = √25 + 16
√41 (And if you need to, you can put this into decimal form.)
We are to solve the total area of the pyramid and this can be done through area addition. We first determine the area of the base using the Heron's formula.
A = √(s)(s - a)(s - b)(s - c)
where s is the semi-perimeter
s = (a + b + c) / 2
Substituting for the base,
s = (12 + 12 + 12)/ 2 = 18
A = (√(18)(18 - 12)(18 - 12)(18 - 12) = 62.35
Then, we note that the faces are just the same, so one of these will have an area of,
s = (10 + 10 + 12) / 2 = 16
A = √(16)(16 - 12)(16 - 10)(16 - 10) = 48
Multiplying this by 3 (because there are 3 faces with these dimensions, we get 144. Finally, adding the area of the base,
total area = 144 + 62.35 = 206.35
Answer:
h squared is 65 but h is 8.06
Step-by-step explanation:
use the pythagorean theorem
7^2+4^2=
49+16= 65
square root of 65 is 8.06
