He ratio of trucks to cars is 6 to 2. If there are a total of 24 trucks, how many cars are there?
2 answers:
Answer:8
Step-by-step explanation:
Truck:car
6:2 or simplified to 3:1, which means 3 trucks for every 1 car.
24 trucks divided by 3 gives you 8.
Answer:
8 cars
Step-by-step explanation:
Set up a proportion to model this situation. First, write and simplify the given proportion.
trucks to cars;
6 : 2
Simplify,
3 : 1
Assuming that the rate at which trucks and cars are present in the parking lot is constant, one can make the expression,
trucks : cars
3 : 1 = 24 : x
Where (x) represents the unknown amount of cars. One can use cross products to solve this proportion,
3 : 1 = 24 : x
24 = 3x
Inverse operations,
24 = 3x
8 = x

Answer: 72
Step-by-step explanation:
V=1/3bh
B= 6*6= 36
H=6
1/3*36*6
I'm pretty sure you add all the sides up together. So I think the answer to this would be 61 but I'm not 100% sure
I assume you need the difference between the percentages,
if
132 mil...........................100%
9.2 mil............................x
x=(9.2 mil * 100)/132= 6.96%
142 mil...........................100%
13.4 mil..........................y
y=(13.4 *100)/142= 9.43%
the difference is
9.43-6.96=2.47 %
