6 gallons, if there is 216 gallons in 36 tubs you have to take 216÷36 to get 6 gallons. To check your answer you can take 36 × 6
Answer:
y = -2x+2
Step-by-step explanation:
A quadratic equation is an equation whose leading coefficient is of second degree. The time can not be negative, therefore, the time in which the athlete complete the jump is 0.75 seconds.
<h3>What is a quadratic equation?</h3>
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
The jump is represented by the equation h(x)= -16x²+4x+6. The time is represented by x, now the height of the athlete will be zero when the jump will be completed therefore, we can write,
0 = - 16x² + 4x + 6
0 = - 16x² + 12x - 8x + 6
0 = -4x(4x-3) -2(4x-3)
0 = (-4x-2)(4x-3)
x = -0.50, 0.75
Since the time can not be negative, therefore, the time in which the athlete complete the jump is 0.75 seconds.

(9.2-4.9÷7) +36.4
first divide -4.9 by 7 in the parenthesis.
9.2-0.7+34.6
now add -0.7 and 34.6
9.2+33.9
now add these numbers together and your answer is.... 43.1
