Answer:
area of the original square = 144 cm²
Step-by-step explanation:
You didn't include the whole question, but nonetheless this is the answer.
Take care. (:
Z is directly proportional to x, that means :
z = k.x, with k is the coefficient of proportionality:
Let calculate k:
When x = 5, z = 55. Plug in:
55 = k.5 → k=55/5 ; k =11
The value of z when = 12 is : z= kx; z = 11(12) and z = 132
she ran 2/3 mile in 1/6 hour, which means she ran 1/3 of a mile in 1/12 of an hour
so 1 mile would be run in 1/12 + 1/12+ 1/12 ( = 1/4 of an hour)
there are 4 quarters to an hour so she is running at 4 miles per hour
Alright, lets get started.
Lets convert the efficiency of the car from miles/gallon to kilometers/liters.
13.62 km/liter
For 13.62 km, it takes gas = 1 liter
For 410 km, it takes gas =
= 30.10
30.10 liters of gas will you need to complete a 410.0 km trip. : Answer
