Answer: 6.7 mm
Step-by-step explanation:
The area of a square is equal to side(side), but is also equal to 1/2(apothem)(perimeter).
The apothem is the perpendicular distance from the center of the square to the midpoint of its side.
We can use these formulas to find the apothem and use the pythagorean theorem to find the hypotenuse (slant height).
Area of square = 9(9) = 81
Area of square = 1/2(apothem)(perimeter)
Perimeter = 4(9) = 36
81 = 1/2(apothem)(36)
162 = apothem(36)
apothem = 4.5
Pythagorean theorem: 
Plug the apothem and the given height into the equation:
(x being the slant height)
20.25 + 25 = 
x = 
x ≈ 6.7
Answer:
It is a parallelogram, I don't know what specified method you want us to use
For this case we define the following variables:
x: Number of party dresses
y: Number of suits
You have 30 hours per week to cut, that is, the first equation is given by:

It is also known that 25 hours per week are available for sewing, that is:

It has a system of two equations with two unknowns, solving we have:

Multiplying the second equation by -1:

Adding up:

Substituting x in the first equation:

Clearing and:


Thus, per week, the designer can produce 5 party dresses and 5 suits working at her maximum capacity.
Answer:
5 Party dresses
5 Suits
Answer:
366.
-1493.
Step-by-step explanation:
54.8-6.9-12
You perform the multiplications first:
= 432 - 54 - 12
= 378 - 12
= 366.
5-2.83.9-4
= 5 - 166* 9 - 4
= 5 - 1494 - 4
= -1489 - 4
= -1493
