Good evening
Answer:
<h2>130</h2><h2 />
Step-by-step explanation:
let L represent the length of the hypotenuse :
Since we are in a right triangle case then the Pyth theorem is a valid choice to solve the problem :
the Pythagoren theorem states that :
L² = 50^2+120^2
then
L² = 16 900
then
L = √(16 900)
=130

Assume that the dimensions of the room in the plan are a (width ) by b (length),
such that a*b=30.
Since the scale is 1:100, a represents 100a, and b represents 100b.
So the actual dimensions are 100a by 100b.
The area is 100a*100b=a*b*10,000=30*10,000=300,000 (square units)
Answer: 300,000 (square units)
Answer: $21.20
Step-by-step explanation:
first, find the profit carmen makes on each pie
12.99 - 8.75 = 4.24
now, we multiply that by the 5 pies that she sold to see what profit she made
4.24 x 5 = 21.2
$21.20
Answer:
c. 15in
Step-by-step explanation:
Line 1:
Expanding the vertex form, we have
x² + 2·1.5x + 1.5² - 0.25 = x² +3x +2
Expanding the factored form, we have
x² +(1+2)x +1·2 = x² +3x +2
Comparing these to x² +3x +2, we find ...
• the three expressions are equivalent on Line 1
Line 2:
Expanding the vertex form, we have
x² +2·2.5x +2.5² +6.25 = x² +5x +12.5
Expanding the factored form, we have
x² +(2+3)x +2·3 = x² +5x +6
Comparing these to x² +5x +6, we find ...
• the three expressions are NOT equivalent on Line 2
The appropriate choice is
Line 1 only
