<u>Answer</u> :-</h2>
To find the cost of planting grass , we have to find area of the field.
Area of field = Length × Breadth


Now convert into hectare.
1 hectare = 10000m sq.
51000 / 10000
So area field = 5.1 hectare sq.
Now cost = 5.1 x 0.80 p

Answer:
The angles are 65° and 115°
Step-by-step explanation:
Let
x,y ----> the two side interior angles of two parallel lines
we know that
x+y=180° ----> equation A
x-y=50° ----> equation B
Adds equation A and equation B
x+x=180°-50°
2x=130°
x=65°
Find the value of y
x+y=180° -----> 65°+y=180° ----> y=180°-65°=115°
therefore
The angles are 65° and 115°
There are four (4) colors to choose from. The number of sample space is equal to 4. With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4. Similarly, the probability of landing on yellow on the second spin is 1/4.
P = (1/4)(1/4)
P = 1/16
Answer: 1/16
