Answer:
D
Step-by-step explanation:
Let x be Bill’s scores.
Let y be Theo’s scores.
x + y = 90
x² = y
Solve for x in the second equation.
x = √y
Put x as √y in the first equation and solve for y.
√y + y = 90
√y = 90 - y
y = (90 - y)²
y = - y² - 180y - 8100
0 = -y² - 181y - 8100
0 = (-y+81)(y-100)
-y+81=0
y = 81
y - 100 = 0
y = 100
100 does not work if we plug in to check, so y is 81.
y = 81
Put y as 81 in the first equation and solve for x.
x + 81 = 90
x = 9
Bill scored 9 goals and Theo scored 81.

Answer:
5 pounds
Step-by-step explanation:
the volume of the container = 2*1.5*3.5= 10.5cubic foot.
Density of the content = 0.49 pound per cubic foot.
As already know,
Density = mass/ volume.
therefore, mass = density * volume.
mass of the content = 0.49 * 10.5 =5 pounds approximately
