Answer:
k = 10
Step-by-step explanation:
The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.
So 10k + 15 must equal the remaining 115
subtract 15 from each side and you get 10k = 100
divide each each by 10 and you get the answer of k = 10
The answer to the proportion is t=52.5
The first one is 19,487,171 and the second is 7,776
Answer:
40
Step-by-step explanation:
A rain barrel is 65$ full
There are 26 gallons of water in the barrel
Therefore the numberr of gallons of water the barrel will hold can be calculated as follows
= 26×100/65
= 2600/65
= 40
Hence the barrel will hold 40 gallons of water
