Answer: He planted 670 acres of corn.

Step-by-step explanation:

Let x be the number of acres of corn and y be the number of acres wheat Farmer planted.

According to the given information, we have the following system of equations:

x+y=1180--------------(1)\\\\ 270x+135y=249750-----------------(1)

Divide equation (2) by 135 , we get

2x+y=1850---------------(3)

Subtract eqn (1) from (3), we get

x=670

Put value of x in (1), we get

670+y=1180\\\\ y=1180-670=510

Hence, he planted 670 acres of corn.

Answer: 4/3 hours or 1 1/3 hours

Step-by-step explanation:

From the question, we are told that two mechanics, Martin and Gordon, are working on your car. Martin can complete the work in 4 hours, while Gordon can complete the work in 2 hours.

Since Martin can complete the work in 4 hours, that means in 1 hour, he will do 1/4 of the work.

Since Gordon can complete the work in 2 hours, that means in 1 hour, he'll do 1/2 of the job.

When they both work together, we will add their fraction of work done in one hour together. This will be:

= 1/4 + 1/2

= 3/4

This means that both of them will do 3/4 of the job in one hour. Then to get the time taken to get the whole job done, we divide 1 by 3/4. This will be:

= 1 ÷ 3/4

= 1 × 4/3

= 4/3 hours

= 1 hour 20 minutes.

OLga [1]

Answer:

<u>There are 60 toddlers in the preschool class</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Percentage of the toddlers in a preschool class drink water with their lunch = 5

Number of the toddlers in a preschool class drink water with their lunch = 3

2.  How many toddlers are in the class?

We'll solve the question, using the Direct Rule of Three, this way:

Percentage      Toddlers

      5                       3

    100                     x

*******************************

5x = 3 *100

5x = 300

x = 300/5

x = 60

<u>There are 60 toddlers in the preschool class</u>
