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.
Answer:
x=7
Step-by-step explanation:
We have been given all exterior angles of a quadrilateral which is a polynomial having 4 sides
We know that sum of all exterior angles of a regular polygon is always 360 degree.
So we can all given exterior angles and set it equal to 360
(12x+37)+(12x-2)+(46)+(20x-29)=360
12x+37+12x-2+46+20x-29=360
12x+12x+20x+37-2+46-29=360
44x+52=360
44x=360-52
44x=308
divide both sides by 44
x=7
<u>Hence final answer is x=7.</u>
Hello! The salary goes up 20% due to the promotion. His original salary was $20,000. To find out his new salary, you have to do is multiply the original price by the rate. 20,000 * 20% (0.2) is 4,000. His promotion is $4,000. Now, we add. 20,000 + 4,000 is 24,000. There. Perry's new salary is $24,000.
