Answer:
The other two vertices have coordinates (4,4) and (10,8). He will need 40 meters of fence for the soccer field. And inside the fence there are 48 square meters, which is a 24% of the total surface of the land behind his house, assuming it is a square of 10 meters of lengt and 10 meters of width.
Step-by-step explanation:
Since the coordinates must form a rectange, then, the other two location must be (4,4) and (10,8) (each coordinate must have something in common with the coordinates of the 2 locations we were given).
The sides of the fence have length 8-4 = 4, and 10-4 = 6. Thus, the perimeter of the fence is 2*4+2*6 = 20 units. Since each unit is 2 meters, then that means that Jonas will need 40 meters of fence.
The area inside the fence is 6*4 = 24 square units, therefore it is 48 square meters, and assuming that the grid goes from 0 to 10 in both coordinates, the area of the land behind his house is 10*10 = 100 square units, thus it is 200 square meters. He is using 48/200*100 = 24% of the land for the soccer field.
Answer:
Cost: $13,680.82
Number of pairs of skates: 1057.25 / 1057-1058
Step-by-step explanation:
To find the cost of the wheels, we need to multiply the cost of a set, $6.47, by the number of wheels needed, 8458, for a quotient of 54723.26. We then divide this quotient by 4, the number of wheels in each set, to get the cost of $13,680.82.
Next, to find the number of pairs that Adam can put wheels on, we divide 8458, the number of wheels Adam has, by 8, the number of wheels Adam puts on each pair of skates. This leaves us with a quotient of 1057.25 pairs. The two whole numbers this number is between are 1057 and 1058.
Answer:
Cost to paint 4 walls of a room = $24.20
Cost of painting 3 walls of a room =$18.15
Step-by-step explanation:
(a) Abby purchased 4 2/5 gallons of paint to paint 4 walls of a room in her house.
1 gallon cost = 5.50
So 22/5 gallons cost =
Cost to paint 4 walls of a room = $24.20
(b)cost of painting 4 walls of a room = $24.20
cost of painting 1 wall of a room =
Cost of painting 3 walls of a room = 6.05 * 3= $18.15
