24 minutes are spent working on science homework.

Given,

time spend for homework is

4/5 hours = 4/5×60 = 0.8×60 = 48 minutes

if 1/2 of this time is spent on working science homework

48×1/2= 48×0.5= 24 minutes

Hence, the total minutes spent, working on science homework is 24 minutes.

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

a = -1/2

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

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

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.

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

Answer:

Step-by-step explanation:

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

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.
