Answer:

9.6km / 9600m

Step-by-step explanation

B= 0.5km

L = 0.7km

perimeter of a rectangle = 2(L+B)

= 2( 0.7 + 0.5)

= 2.4km

wire for one round is 2.4km

wire for 4 rounds = 2.4 x 4

                             = 9.6km wire is required.

Hence, 9.6km wire is required to fence the rectangular piece of land 4 times.

Suki buys dog food in large 13.4-pound bags. She feeds her dog 0.3 pound of food twice a day. How many full days will the bag of
kozerog [31]

Hi!

Suki feeds her dog 0,3 pound of food twice a day, which means that in one day, Suki gives her dog 2 * 0,3 = 0,6 pound of food.

The total amount of dog food Suki bought for her dog is 13,4 pound-bag. To find the number of days the bag of dog food will last, we have to divide the total amount of the bag of dog food, which is 13,4 pounds, by the amount of what Suki gives her dog every day, which is 0,6 pound of food, like this:

13,4/0,6 = (multiply both values with 10) = 134/6 = 22,33

Because it is asked for the number of full days, in this case that's the lower whole number, 22 is the answer.

The bag of dog food will last full 22 days.

Hope this helps!

uranmaximum [27]

Answer:

Part 1: 114,570,685 people

Part 2: The population grew by 2.5% (1,722,862 people)

Step-by-step explanation:  For part 1 you would multiply 100,236,820 by 1.143 because of the fact that your percentage is increasing.  so the 1 before the decimal point stands for 100% of the starting number and the .143 stands for the 14.3% that the population is increasing by.  


Part 2 you would divide 53,594,378 by 55,317,240 to get approximately .975.  .975 shows that 53,594,378 is about 97.5% of 55,317,240.  You then subtract the numbers 100 and 97.5 to get 2.5.  2.5 is the percentage that the population is increasing by.  So, then you could just subtract 55,317,240 and 53,594,378 to get 1,722,862.  This is the amount of people the population increased by.  Then you just put your answer that the population increased.  That it increased by 2.5% and 2.5%= 1,722,862 people

I hope this helps you :)
