Here's a riddle
A horse travels a certain distance each day. Strangely enough, two of its legs travel 30 miles each day and the other two legs travel nearly 31 miles. It would seem that two of the horse's legs must be one mile ahead of the other two legs, but of course, this can't be true, since the horse is normal. How is this possible?
You can search the answer

Answers

Answer: the horse does more work on one of the pairs so they went a different distance.

Answer:

The horse operates a mill and travels in a circular clockwise direction. The two outside legs will travel a greater distance than the two inside legs.

The plan of a patio deck is shown at the right. The scale is 2 inches: 6 feet. What are the length and width of the deck

Answers

Answer:

5in.=15ft. 2in.=6ft.

Step-by-step explanation:

What you have to do is translate 6ft. into inches which is 72in. Then you divide that by 2in. From that you get 36in. You then take that 36in. and multiply it by the 5in for the length. from that you get 180in. You divide the 180in. by 12 to turn your inches into feet and you end up with 15ft.

I hope this helps.

a car drives 10 1/2 miles in 1/6 hour. what is its speed in miles per hour

Answers

(Credit to guy/girl above) 63 miles 10 1/2 x 6 is 63.

The speed for the given distance and time is 12.6 miles per hour.

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, a car drives [tex]10\frac{1}{2}[/tex] miles in 1/6 hour.

We know that, the formula to find the speed is Speed=Distance/Time

Speed = [tex]10\frac{1}{2}[/tex] ÷ 1/6

= 21/10 ×6/1

= 63/5

= 12.6 miles per hour

Therefore, the speed for the given distance and time is 12.6 miles per hour.

Explain why the value of 0.6 is greater than the value of 0.39.

i know why... i just need help explaining plz! i will give brainliest

Answers

Answer:

the value 0.6 is greater than 0.39 bc 0.6 is a bigger value than 0.39 as u go down the values get more bigger and as u go up the values get more smaller. try this if not then I will tell u another thing.

Answer is 0.60 > 0.39

Decimal place value:

The decimal place value is the place value of the digits in a decimal number. We know that place value is the numerical value represented by a digit in a number.

Ex: 0.50 > 0.49 as the tenth place of 0.50 is more than 0.49.

Here,

0.6 = 0.60

0.60 > 0.39 as the tenth place of 0.6 i.e., 6 is greater than 0.39 i.e., 3.
