A gas pump fills 2^-2 gallon of gasoline per second. how many gallons does the pump fill in one minute?
astraxan [27]

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

  • Given that a gas pump fills 2^-2 gallon of gasoline per second.

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

60\:\times 2^{-2}

=60\times \frac{1}{2^2}             ∵ a^{-b}=\frac{1}{a^b}

\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}

=\frac{1\times \:60}{2^2}

=\frac{60}{2^2}

=\frac{2^2\times \:3\times \:5}{2^2}

=3\times \:5

=15 gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15

Factor the expression completely
Phantasy [73]
Factor : 8y - 36

Go through all of the answer choices & see which one is correct.

a) -4 (2y + 9)

You don't even have to fully simplify this, just by looking at the -4, you already know that this is incorrect because you need to have a positive 8. So, A is incorrect. 

b) 8 (y - 4)

Simplify.

8y - 32

Incorrect because it is not equal to the original equation.

c) 2 (4y - 18)

Simplify.

8y - 36

Correct answer because it is equal to the original equation.

d) 4(2y - 9)

Simplify.

8y - 36

D is also correct.

So, your answer is : (C) and (D) are your answers.

Can someone help me with this asap (algerbra)

<u>PEMDAS</u>

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.

First, divide 3 from both sides of the equation:

\frac{(3x^2)}{3} = \frac{(48)}{3}

x^{2} = \frac{48}{3}\\ \\x^2 = 16

Next, isolate the variable, x, by rooting both sides of the equation:

\sqrt{x^{2} } = \sqrt{16}\\ x = \sqrt{16} = \sqrt{4 * 4}

x = ±4

C) ±4 is your answer.
