Which animal traveled at a rate of 1.5 meters per minute?
Fofino [41]

Answer:

The ant

Step-by-step explanation:

We know that the meters traveled is going to be more than the amount of minutes because it is 1.5:1 so that narrows it down to the turtle and the ant.

Now we can just take 150% of each and see if they match up.

150% of 5 is 7.5 so therefore it is not the Turtle which means it must be the ant.

Hope this helped ! !

if it did please consider marking brainliest i would appreciate it greatly :)

Scott wants to buy fencing to place around a semicircular rock garden The diameter of the semicircle is 16 feet Using 3.14 for p
Pavel [41]

The diameter of the semicircle is 16 feet.

He calculates that he needs to buy abut 25.12 feet of fencing.

To find amount of fencing we find the circumference of semicircle

Circumference of semicircle = \frac{1}{2}\pi d+d

Where d is the diameter of the circle

d= 16 given and value of pi is 3.14

Circumference of semicircle = \frac{1}{2}*3.14*16+16

=25.12 + 16 = 41.12 feet

Scott's calculation was wrong because he forgot to add the diameter d

Circumference of circle  is half way of circle plus the diameter of circle.

Correct amount of fencing = 41.12 feet
