There is 273 thousands. Remember, take out your zeros. Hope it helps! :)
So they're proportional.
This means that the 2 triangles are exactly the same BUT the right one is smaller than the other, so all measurements are smaller too.
So to find the distance, you need to find the scale factor.
Think of it like this: 82m becomes 73.8m, and 92m becomes 82.8m.
Find the scale factor by finding the ratio.
73.8/82 = 9/10 or 0.9
You could do the same thing with the other two numbers too (92/82.8), gives the same answer.
Times the ratio by the distance of the bigger triangle:
0.9 x 47 = 42.3m
Answer:
33 by 45 meters
Step-by-step explanation:
The perimeter is twice the sum of adjacent side lengths, so the sum of the dimensions is 78 meters. If x is one of the dimensions, then 78-x is the other, and the area is their product:
x(78 -x) = 1485
Subtracting the left side, we get ...
x^2 -78x +1485 = 0
This can be graphed as ...
y = x^2 -78x +1485
and the zeros will reveal the dimensions.
The attached graph shows them to be ...
33 by 45 meters
Answer:
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(3x−6)−2x+1=25
(2)(3x)+(2)(−6)+−2x+1=25(Distribute)
6x+−12+−2x+1=25
(6x+−2x)+(−12+1)=25(Combine Like Terms)
4x+−11=25
4x−11=25
Step 2: Add 11 to both sides.
4x−11+11=25+11
4x=36
Step 3: Divide both sides by 4.
4x

Answer:
-m^3 - 3m^2 +2m -4
Step-by-step explanation:
(m^3-3m^2+m-1)-(2m^3-m+3)
Distribute the minus sign
(m^3-3m^2+m-1)-2m^3+m-3
I like to line them up vertically
m^3-3m^2+m-1
-2m^3 +m-3
--------------------------
-m^3 - 3m^2 +2m -4
