Flura [38]

11/3. This is because you multiply the denominator by the mixed number. Than you add the numerator to that. Put that number over the denominator you had in the original problem. Hope this helps!

Hurry !!!A typical barrel of bot-oil contains 70 liters of oil. If a hole in the barrel is causing a constant 6 liters an hour l

Tom [10]

Answer:

y = -6x + 70

Step-by-step explanation:

Since the amount of oil in the tank decreases constantly, we need to create a linear function. Using the base form, y = mx + b, we can replace -6 for m because volume decreases by 6 (or increases by -6) each hour, and +70 for b because we start off with 70 liters of oil. So we get y = -6x + 70, with x representing the number of hours, and y representing the volume of oil remaining.

Answer:

$3,813.33 \: {cm}^{3}$

Step-by-step explanation:

Volume of the space that is not occupied = Volume of cube shaped box - volume of soccer ball

$= {20}^{3} - \frac{4}{3} \times 3.14 \times {10}^{3} \\ \\ = 8000 - \frac{4}{3} \times 3.14 \times 1000 \\ \\ = 8000 - \frac{4}{3} \times 3140 \\ \\ = 8000 - \frac{12560}{3} \\ \\ = 8000 - 4,186.66667 \\ \\ = 3,813.33333 \\ \\ = 3,813.33 \: {cm}^{3}$

Artemon [7]

(a) $x^{2}$ = 400
(b) $\sqrt{x^2} = \sqrt{400}$
$x=20,-20$
(c) Only the positive solution makes sense because you cannot have a negative side length.
(d) Since one side of the painting is 20 inches, all four sides together will be 20*4 = 80 inches
