We sketch two triangles, DFE and DGH, as shown below
Side DF correspond to side DG, the scale factor is 40÷32=1.25
Side DE correspond to side DH, the scale factor is 30÷24=1.25
That leaves us with the last corresponding sides, EF and HG which would also have a scale factor 1.25
Both triangles share the same angle D
We can conclude triangle DFE and triangle DGH are similar for property SSS and SAS
Answer:
192 gallons
Step-by-step explanation:
1.6 gallons x by 4 (the amount of times flushed in a day) = 6.4 gallons a day
6.4x30 (days in a month) = 192
192 gallons of water is being flushed a month
Answer: 20/5

Divide 20/5
Answer: -4.775
Step-by-step explanation: 11(7/8) + 3(1/5) - (-4.775) = 15
Answer:
15 and 108
Step-by-step explanation:
3*(30-25)=3*5=15
