Answer:
A
Step-by-step explanation:
73+107 = 180. When the smaller of the two angles is 73 all of the smaller angles are also going to be 73 and since the angles MTS and STN are bigger angles they both have to be 107
Answer:
3:1
54:18
Step-by-step explanation:
You can divide both sides by 9 to get one ratio:
27/9:9/9
3:1
You can also multiply both sides by 2 to get another ratio:
27(2):9(2)
54:18
Gas is 2.45 per gallon. So if we pay $12 we get 12÷2.45 gallons:
12 ÷ 2.45 ≈ 4.90 gallons.
You get roughly 4.90 gallons.
let's recall that a year has 12 months, so 15 months is really 15/12 years.
