I would have to say SAS because they give 2 sides and an angle. Also 3:4 because the one side is 3 and add 1 for 4, same for 30 and 40.
Answer:
4.30 naira
Step-by-step explanation:
Splitting in half, we have that they both get 3.60 naira each. Adding 70 kobo to 3.60 naira, we have 4.30 naira. Since we need Tayo's share to be 70 kobo more than Bisi's, we give Tayo the bigger share and the left cash to Bisi (2.90 naira).
Answer: a. 126.20 gallons.
b. 2740 miles.
Step-by-step explanation:
We will use unitary method in this question.
a) ∵ 310 miles can be covered by a car with the help of 15.5 gallons of gasoline
∴ 1 mile can be covered = gallons
∴2524 miles can be covered =
= 126.20 gallons
b). ∵ With 15.5 gallons of gasoline car can be driven = 310 miles
∴ With 1 gallon of gasoline car can go = 310/15.5 miles
∴ With 137 gallons can can go = (310×137)/15.5 miles
= 2740 miles.
We use the law of Cosines to find b=AC opposite B
We know all the sides of triangle ABM so we can use the law of Cosines, this time to solve for
Substituting,
Answer: AC=√39
