The number of groupings = 11C3 + 11C2 = 165 + 55 = 220
Answer:
A) x = .9y
B) x + .9y = .038
Substituting A) into B)
.9y + .9y = .038
1.8y = .038
y = .038 / 1.8
y = 0.0211111111
From equation A)
x = .038 -.9*.02111111111111111111111
x = .038 -.019
x = .019
CHECK
x * .9 = .019
.019 + .9 * .021111111111111 = .019 + .019 = .038
Step-by-step explanation:
Answer: 4/7

Answer:
117 yards
Step-by-step explanation:
From the diagram here, we can see that we are to calculate the diagonal of the rectangular football field
we can calculate this by the use of Pythagoras’ theorem which posits that the square of the hypotenuse = the sum of the squares of the two other sides
From the diagram, the diagonal is the hypotenuse while the other two sides complete the right triangle
let’s say the diagonal is length d
Mathematically;
d^2 = 100^2 + 60^2
d^2 = 10,000 + 3,600
d^2 = 13,600
d = √13,600
d = 116.62 yards which is approximately 117 yards
