The triangle is drawn and is shown in the image attached with.
We get two similar triangles. Triangle ABC and Triangle ADE. Since the triangles are similar the ratio of their corresponding sides will be the same.
D and E are the midpoints of AB and BC, therefore, AD and AE are both 4 units in length. Using the property of similar triangles, we can say:
AD : DE= AB : BC
AD = 4 units
AB = 8 units
BC = 6 units
DE = unknown = x units
So,
Therefore,
the length of DE will be 3 units
Answer:
56,000
Step-by-step explanation:
The scale drawing is a 1/40 ratio so you multiply 5 by 40 and you get 200. You do 200x280 and you get 56,000.
10/100 = x / (810+x)
1/10 = x / (810 + x)
10x = 810 + x
9x = 810
x = 90 g salt
mass of solution = mass of water + mass of salt
ms = mw + m salt
ms = 810 + 90
ms = 900 g of solution
