A group of friends went on a three-day hike. During the second day of the hike, the group hiked twice as far as they did on the
Talja [164]

Answer: they hiked 2 miles on the first day.

Step-by-step explanation:

Let x represent the distance that the group hiked on the first day.

During the second day of the hike, the group hiked twice as far as they did on the first day. This means that the distance that they hiked on the second day is 2x.

On the third day, they hiked twelve miles farther than combined distance of the first two days. This means that the distance that they hiked on the third day is x + 2x + 12

In all, they hiked 24 miles. This means that

x + 2x + x + 2x + 12 = 24

6x + 12 = 24

6x = 24 - 12 = 12

x = 12/6 = 2 miles

Answer:

48!

Step-by-step explanation:

If the plot of land is a square, then the area can be found by multiplying one side by another.  You'll have to multiply each number by itslef to see if the answer ranges anywhere between 2200 and 2400.  48 x 48 = 2304.  2304 is a number in between 2200 and 2400, and it is the only answer that is between 2200 and 2400.  So, 48 can be one of the possible side lenghths of that square plot of land.

posledela

Answer:

63 feet.

Step-by-step explanation:

The total diameter of the circular garden is given by 5ft+ 10 ft + 5 ft= 20 feet

As the circumference of the circle = 2πr where r = radius obtained by dividing the diameter by 2. Here the diameter = 20 feet and r= d/2 = 20/2 = 10 feet

Putting the values in the circumference formula

Then C= 2(22/7) (10)= 62.85 feet

Rounding gives almost 63 feet .
