Answer:

To fix the mixture to the correct shade of red, you can add 9 quarts of red, 7 quarts of yellow and 4 quarts of white.  

Step-by-step explanation:

The problem tell us the a specific shade of red nail polish needs the following ratio:  7 parts red to 2 parts yellow to 5 parts white or 7:2:5.  However, the current mixture contains a ratio of 40:7:31 and does not follow the same ratio as the given mixture.  In order to fix the mixture to make the correct shade, we will need to add additional quarts of each color in order to make our ratio a multiple of 7:2:5.  Given that 40 quarts is between the multiples of 42 and 49 for the number 7 and 31 is between the multiples of 35 and 40 for the number 5, it would make the most sense to multiply each number in the ratio by 7 to get:  49:14:35 and add the difference in the quarts to the mixture.  49 - 40 = 9 quarts red; 14 - 7 = 7 quarts yellow; 35 - 31 = 4 quarts white.

For an angle θ, tan(θ) is a negative number. Which quadrants might θ be in?
Klio2033 [76]

So for this question, we're asked to find the quadrant in which the angle of data lies and were given to conditions were given. Sign of data is less than zero, and we're given that tangent of data is also less than zero. Now I have an acronym to remember which Trig functions air positive in each quadrant. . And in the first quadrant we have that all the trig functions are positive. In the second quadrant, we have that sign and co seeking are positive. And the third quadrant we have tangent and co tangent are positive. And in the final quadrant, Fourth Quadrant we have co sign and seeking are positive. So our first condition says the sign of data is less than zero. Of course, that means it's negative, so it cannot be quadrant one or quadrant two. It can't be those because here in Quadrant one, we have that all the trick functions air positive and the second quadrant we have that sign. If data is a positive, so we're between Squadron three and quadrant four now. The second condition says the tangent of data is also less than zero now in Quadrant three. We have that tangent of data is positive, so it cannot be quadrant three, so our r final answer is quadrant four, where co sign and seek in are positive.

3/10 multiply to find an equivalent fraction
SCORPION-xisa [38]
<span>You multiply both the numerator and the denominator by the same number (but not 1 or 0), but don't simplify. 3/10 is your fraction, and you could multiply the top and bottom numbers by 2 to get 6/20.

I hope I helped please leave thanks

Solve the compound inequality. Graph your solution. 2x – 2 &lt; –12 or 2x + 3 &gt; 7 x &lt; –5 or x &gt; 5 x &lt; –5 or x &gt; 2
Brilliant_brown [7]

Answer:

The solution region is x < –5 and x > 2

Step-by-step explanation:

We are given the inequalities, 2x–2 < –12 or 2x+3 > 7

Upon simplifying the inequalities, we get,

A. 2x-2 < -12

2x-2 < -12 i.e. 2x < -10 i.e. x < -5

B.  2x+3 > 7

2x+3 > 7 i.e. 2x > 4 i.e. x > 2

So, we get the solution is x or x>2 and the plotted region can be seen below.
