Answer:
1 and ahalf, so 1 1/2
Step-by-step explanation:
Answer:
15x^2 - 14x - 8 = 0.
Step-by-step explanation:
(x - 4/3)(x + 2/5) = 0
Converted to integer values by multiplying the first bracket by 3 and the second by 5:
(3x - 4)(5x + 2) = 0
Expanding the brackets:
15x^2 + 6x - 20x - 8 = 0
15x^2 - 14x - 8 = 0.
Answer:
(1) True
(2) False
(3) True
(4) True
Step-by-step explanation:
(1) It is true Darla can use either the height of 6 m or 5 m to find the area of the triangle because Darla already knows the measurement of a side of the triangle. Multiplying the side by either of the heights divided by 2 gives the area of the triangle.
(2) It is false they will find the same area of the triangle.
Area of triangle = (side×height)/2
Darla's area of the triangle = (9×6)/2 = 54/2 = 27 m^2
Rico's area of the triangle = (7.5×5)/2 = 37.5/2 = 18.75 m^2
(3) It is true they will find the same area of the triangle.
Rico's area of the triangle = (7.5×6)/2 = 45/2 = 22.5 m^2
Darla's area of the triangle = (9×5)/2 = 45/2 = 22.5 m^2
(4) It is true the area of the triangle is 22.5 square meters as shown in part (3) above.
You need to figure out the number of teams in the lower quartile in order to figure out the answer
