Answer:

3 pigs

Step-by-step explanation:

First split the shape into two rectangles to find the area. On the left you can make the rectangle 10*7 and on the right subtract 7 from 16 to get 9 so the one on the right is 9*6. Find the area of both rectangles by multiplying, which will get you 70 and 54 respectively. Add these to get 124 square meters of space in the field. Now you will have to divide it by 36 to see how many pigs can fit, which results in the answer 3.4444... Round down to get 3 pigs as you can not fit another pig in the .4444... of space.

Hello,

1)
I don't if in USA, we count beginning with 0 or beginning with 1

if you count 0,1,2,3,4,5,6... a(0) being the FIRST term the answer is A
if you count 1,2,3,4,5... a(1) being the first term (in this case how do you call a(0) the zeroth term?) the answer is C

In Europ, the first term is a(0).

2)

a(1)=8 Is it the FIRST term?
a(n)=a(n-1)-2

43 is 120% of what number? 0.36 3.58 358.33 35.83

Answers

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that 120% of a number is 43.

Let the number be x.

$x* (120)/(100)=43$

$x* (12)/(10)=43$

Multiply both sides by 10.

$x* 12=43* 10$

$12x=430$

Divide both sides by 12.

$x=(430)/(12)$

$x=35.8333333333$

$x\approx 35.83$

The required number is 35.83. Therefore the correct option is 4.
