Answer:
The fraction of students who likes soccer or basketball is 7/10.
Step-by-step explanation:
In this case we have two groups of students, the group a is the one that prefers soccer, while the second group is the one that prefers basketball. We then need to find the fraction that represents the students that are in either group, in these cases we need to take the fractions of each group and sum them. So we have:
soccer OR basketball = soccer + basketball
soccer OR basketball = 2/5 + 3/10
Through LMC we have:
soccer OR basketball = (2*2 + 3)/10 = (4 + 3)/10 = 7/10
The fraction of students who likes soccer or basketball is 7/10.
The area of a circle is A = r^2pi
Since the area is equal to 121pi the equation would be, 121pi = r^2. To find r in terms of pi take the square root of 121, to find the radius. Then multiply that by two to get the diameter.

Step-by-step explanation:pls mark me
To determine the cost to fertilize the trees, you need to figure out how many kilograms of fertilizer are needed. With the information given, you can determine The number of grams needed to fertilize 1200 trees. To do this you would multiply 200 times 1200. This equals 240,000 grams. To convert this to kilograms, divide 240000g by 1000 g. Every group of 1000 g is 1 kg. The answer is 240 kilograms. Multiply 240 kg by the price of $2.75 per kilogram to get $660 as the cost.
