As long as there are no numbers after them the zeros on the right of the decimal don't matter (i.e. 6.3000000=6.3 3.00000=3)
So 81.9=81.90=81.900
Since three of them are the same number there is only one answer left (81.91)
Answer:
architect because they need to determine the length, width, and height of objects, they need to use area to see if there's enough space for what they want to build, etc.

As per the direct variation formula, it take 11 hours : 6 minutes : 36 seconds to earn $25,000 for the restaurant.
Direct variation:
Direct Variation is said to be the relationship between two variables in which one is a constant multiple of the other.
Direct variation equation: y = kx
Given,
A local fast food restaurant takes in $9000 in a 4 hours period. Write a direct variation equation for the relationship income and number of hours.
Here we need to estimate how many hours it would take the restaurant to earn $25,000.
a) Let us consider income (I) directly varies to number of hours (h) where k is the constant of variation.
I = kh ⇒ Direct variation equation
Solve for k:
9,000 = (k)(4)
k = 9,000/4
k = 2,250
b) When income (I) = 25,000, find the number of hours:
I = kh
25,000 = (2,250) (h)
h = 25,000/2,250
h = 11.11
It will take approximately 11 hours : 6 minutes : 36 seconds for the restaurant to earn $25,000.

Answer:
16 units.
Step-by-step explanation:
Just to make things easy, let's name the points A(3,9) B(5,9) C(3, 3) and D(5, 3).
Because this question wants perimeter, we'll just use the distance formula twice, then l*2 + w*2 = p.
Distance formula is sqrt((x1 - x2)^2 + (y1 - y2)^2) = d.
sqrt((5 - 3)^2 + (9 - 9)^2) = 2
sqrt((5 - 5)^2 + (9 - 3)^2) = 6.
The distance of points A and B is 2 units, and B to D is 6 units, multiply both by 2, (2*2=4, 6*2=12) and add the values to find 16 units.
Hope this helps, and if this is for OW, I feel your pain.
