find a:27=6:11, find a
Answer:
a = 14.73
Step-by-step explanation:
This ratio can also be written like this:
[tex]\frac{a}{27} = \frac{6}{11}[/tex]
Then you can cross multiply to get
11a = 6 x 27
11a = 162
Divide both sides by 11
11a / 11 = 162 / 11
a = 14.73

a = -1/2
Hope this helps :)
Answer:
a = -1/2
Step-by-step explanation:
-1/4a - 4 = 7/4a - 3
-a/2^2 - 4 = 7/ 2^2 a - 3
(-a) - ( 2^2) 4 / 2^2 = 7a/ 2^2 - 3

Coordinate planes: Do any of you know any nemonic devices or anything to help me remember quadrant numbers and the positive and negative signs? I have trouble remembering and anytime I look anything up Edgenuity kicks me out because it insists on being cancer.
Step-by-step explanation:
Hello!!!
I can understand how you feel about this. I hope to do my best in helping you understand quadrant numbering and signs.
Now for the number start form the top right and move counter-clockwise, that is
Top right =1st quadrant
Top left = 2nd quadrant
Bottom left = 3rd quadrant
Bottom right =4th quadrant
Basically moving counter-clockwise you will get this
Now for the sign convection
Up and right are both positive
Down and left are both negative.
I hope this helps. Don't forget to let me know should you need any further assistance.
Regards.

Don purchased software for $99.95. How much tax was
charged if the tax rate was 9.5%?
Answer:
9.49525
Step-by-step explanation:
You have the total and the percent so you are looking for the part. You can set up a proportion with 9.5 over 100 and x over 99.95. Then you multiply 9.5 times 99.95 to get 949.525 which then you divide by 100. So x is 9.49525
HAVING A BAD DAY HELP
Christine bakes 20 cookies every half hour. Charlie sells 38 cookies per hour. How many cookies are left unsold if they work from 6:00 AM until noon?
Answer:
12
Step-by-step explanation:
The number of cookies that are left unsold if they work from 6:00 AM until noon is 12.
Cookies baked per hour by Christine = 20*2 =40
Cookies sold per hour by Charlie = 38
How many hours will be there between 6:00 AM and noon?There will be 6 hours between 6:00 AM and noon.
So, Cookies baked by Christine in 6 hours = 40*6 =240
Cookies sold by Charlie in 6 hours = 38*6 =228
Number of unsold cookies =240-228 =12
Hence, the number of cookies that are left unsold if they work from 6:00 AM until noon is 12.

y = 4x - 5 and (3,4) (7, 3) A. parallel B. perpendicular D. neither
Answer:
The lines are perpendicular. Option B.
Explanation:
Equation of the Line
One of the characteristics of the line is its slope. It can be determined in two ways:
* From the equation y=mx+b, the m is the slope. The given equation is y=4x-5. Thus, the slope of this line is m=4.
* Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are (3,4) and (7,3), thus the slope is:
[tex]\displaystyle m=\frac{3-4}{7-3}=-\frac{1}{4}[/tex]
A. For two lines to be parallel, their slopes must be equal. Since m1=4 and m2=-1/4, the lines are not parallel. Incorrect
B. For two lines to be perpendicular, their slopes must meet the condition:
[tex]m1*m2=-1[/tex]
4*(-1/4)=-1
Both lines are perpendicular. Correct choice
D. Since choice B. is correct, this cannot be true. Incorrect
