Triangle R has an area of 40 square units. Salome drew a scaled version of triangle R and labeled it triangle T what scale facto
r did salome use to go from triangle R to triangle T

Answer:
Scale factor = 1/2
Ratio R:T = 2:1
Attached is the missing image;
Step-by-step explanation:
From the image attached;
The height of the triangle T is = 5 units
Base of triangle T = 4 units
Since the two triangles are scaled versions;
Area of a triangle = 1/2 × h × b
For triangle R;
Area = 40 = 1/2 × h × b
hb = 80
And, h : b = 5:4
h= 5/4 b
5/4 ×b × b = 80
b^2 = 64
b = 8
h = 5/4 × 8 = 10
The height of the triangle R = 10 units
Base of triangle R = 8 units
Scale factor = h2/h1 = 5/10 = 1/2
Scale factor = 1/2

Answer:
1. $685 - ( $273 + $119 )
2. $273 + $119
3. $293
Step-by-step explanation:
It is given that,
Vanessa initially has $685.
Vanessa spent $273.
Vanessa donated $119.
1. So, we get that, the expression for the money she was left with is,
Vanessa is left with $685 - ( $273 + $119 ).
2. Since, before subtracting the amount Vanessa spent, we need to calculate the total expense she had.
Thus, the hidden calculation is $273 + $119.
3. We have the problem given by, $685 - ( $273 + $119 ) = $685 - $392 = $293.
Thus, Vanessa is left with $293.
The bar graph for the given problem is shown below.
