Answer:
7 : 1
Step-by-step explanation:
Paul's car goes 40 kilometers on 7 tanks.
Distance : Tanks
49 : 7
Fuel efficiency means the distance traveled by the car in one tank.
Therefore, we will reduce the ratio by dividing both sides by 7.
Distance : Tanks
: 
7 : 1
Therefore, car's fuel efficiency is 7 kilometers in one tank or the ratio between Distance traveled and fuel tanks is 7 : 1.
Answer:
hmm I'm pretty sure a is 3.2
Answer:
Sin 29° 32' = Cos 60° 28'
Step-by-step explanation:
Here in this problem, we have to write Sin 29° 32' in terms of its co-function.
We know that co-function of Sin Ф = Cos ( 90° - Ф ).
Therefore, we have to find a complementary angle of 29° 32'.
So, ( 90° - 29° 32' ) = 60° 28'
Therefore, Sin 29° 32' = Cos 60° 28' ( Answer )
Ok, MissWalker! Please try your best to understand this, it may get confusing.
I have solved this on a different website, and here is my solving in a picture. I hope I helped!!! :D
