Answer:
20*30km = 600km
15*30km = 450km
600km * 450km = 270000 km^2
Step-by-step explanation:
assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map
using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km
Then we use a formula of an area of a rectangle 
assuming 
and get 
which is an actual area of Colorado
Answer:
4
Step-by-step explanation:
1. if the mass of coffee worth $10 is 'x', then its worth is 10x, and the worth of the mixture is 5(x+20);
2. using the previous item it is possible to write the next equation:
5(x+20)=4*20+10*x; ⇒ x=4.
3. the required mass is 4 pounds.

Answer:
1/50* 1/2 =0 .01
Step-by-step explanation:
First, the probability that the spinner lands on 20 is
1
/50
, as 20 is one of the 50 numbers on the wheel, and each number has an equal probability of being selected.
Second, the probability that the spinner lands on an odd number is
1/2
. This is because of the 50 numbers on the wheel, half are even and half are odd.
