23 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
23 centimeter -> x kilometer
We clear x:
x = (23/1) * (1)
x = 23 kilometers
0.5 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
0.5 centimeter -> x kilometer
We clear x:
x = (0.5 / 1) * (1)
x = 0.5 kilometers

9 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
9 centimeter -> x kilometer
We clear x:
x = (9/1) * (1)
x = 9 kilometers

Answer:
c. 23 kilometers
a. 0.5 kilometers
b. 9 kilometers

UNO [17]

Answer:

Option C. Marcelina spends less that the intended amount of money and buy the correct amount of corn

Step-by-step explanation:

<u><em>The complete picture of the question in the attached figure</em></u>

Let

x----> is the amount of white corn she buys

y ---> is the amount of yellow corn she buys

we know that

She needs to buy 50 kg of corn in total

$x+y=50$ ----> equation A

She wants to spend $12 dollars total

$0.30x+0.15y=12$ ----> equation B

The solution of the system of equations is the intersection point both graphs

The solution is the point (30,20)

That means

Marcelina needs to buy 30 kg of white corn and 20 kg of yellow corn

we have the ordered pair D(15.35)

That means

15 kg of white corn and 35 kg of yellow corn

therefore

Total kg of corn bought is

$15+35=50\ kg\\50\ kg= 50\ kg$

Total spend is

$0.30(15)+0.15(35)=\$9.75\\\$9.75$

therefore

Marcelina spends less that the intended amount of money and buy the correct amount of corn
