A 12 ounce mixture of window cleaner is 4% alcohol. How many ounces of the mixture is alcohol

1 answer:

6 0

0.48 ounce is alcohol
Because you have to divide 100% from 12 ounces which is equivalent to 0.12 ounces for 1% now you will have to multiply 0.12 x 4% WHICH is 0.48 ounce

How to do polynomials

Travka [436]

Answer:

Step-by-step explanation:

12/6 is 2 and the the exponents when you are dividing you just subtract. so 9-3 = 6 which makes it x^6.

Please answer! I crossed out the ones you don’t have to complete.

Nina [5.8K]

Answer:

1. Rewriting the expression 5.a.b.b.5.c.a.b.5.b using exponents we get: $\mathbf{5^3a^2b^4c}$

5. $x^-6 = \frac{1}{x^6}$

6. $5^{-3}.3^{-1}=\frac{1}{5^3.3^1}$

7. $a^{-3}b^0c^4=\frac{c^4}{a^3}$

Step-by-step explanation:

Question 1:

We need to rewrite the expression using exponents

5.a.b.b.5.c.a.b.5.b

We will first combine the like terms

5.5.5.a.a.b.b.b.b.c

Now, if we have 5.5.5 we can write it in exponent as: $=5^{1+1+1}=5^3$

a.a as $a^{1+1}=a^2$

b.b.b.b as: $b^{1+1+1+1}=b^4$

So, our result will be:

$5^3a^2b^4c$

Rewriting the expression 5.a.b.b.5.c.a.b.5.b using exponents we get: $\mathbf{5^3a^2b^4c}$

Question:

Rewrite using positive exponent:

The rule used here will be: $a^{-1}=\frac{1}{a^1}$ which states that if we need to make exponent positive, we will take it to the denominator.

Applying thee above rule for getting the answers:

5) $x^{-6} = \frac{1}{x^6}$

6) $5^{-3}.3^{-1}=\frac{1}{5^3.3^1}$

7) $a^{-3}b^0c^4=\frac{b^0c^4}{a^3}$

We know that $b^0=1$ so, we get

$a^{-3}b^0c^4=\frac{b^0c^4}{a^3}=\frac{c^4}{a^3}$

How do you solve this URGENT (50pts)

Aliun [14]

Explanation:

x + 3y = 2

Converting it to slope intercept form:

y = mx + b [where m is slope, b is y-intercept]

Make y the subject:

$\sf \rightarrow 3y = 2 - x$

$\sf \rightarrow 3y = -x + 2$

$\sf \rightarrow y = -\dfrac{x}{3} + \dfrac{2}{3}$

$\sf \rightarrow y = -\dfrac{1}{3} x+ \dfrac{2}{3}$

which reveals slope:

$\star \ slope: \sf - \dfrac{1}{3}$
