Answer:
The new drawing at the left enlarges the size of the original drawing.
Step-by-step explanation:
If I draw the map at the left using a scale of 0.5 cm : 1 cm.
That means the 0.5 cm length in the previous drawing is redrawn in the new map as 1 cm length.
Since 1 cm is larger than 0.5 cm and it is two times of 0.5 cm, so the new drawing at the left enlarges the size of the original drawing. (Answer)
Make use of the fact that side lengths in similar triangles are proportional.
.. 30/18 = (20 +x)/20
.. 20*(30/18) -20 = x . . . . multiply by 20, subtract 20
.. 33 1/3 -20 = x . . . . . . . . evaluate the product
.. 13 1/3 = x
The answer is B. There is a lot that is going to the housing in this problem
To solve this problem you must apply the proccedure shown below:
1. You have that :
-The <span>estimate from the moving is $675 for 6 hours of packing and 5 hours of moving.
- </span>The cost will decrease to $425 for 4 hours of packing and 3 hours of moving.<span>
x: rate for packing.
y: rate for moving.
6x+5y=675
4x+3y=425
2. When you solve the system of equations shown above, you obtain:
x=50
y=75
Therefore, the answer is: $50 (Rate for packing) and $75 (Rate for moving).
