Imagine that the class only had 4 students (unrealistic most likely, but small numbers help much better I think)

If we had 4 students and 3 were boys, then 4-3 = 1 girl is in the class. This makes the ratio of boys to girls be 3 to 1. In other words, there are 3 times as many boys compared to girls.

Divide the number of girls (1) over the number of students total (4) to get 1/4 = 0.25 = 25%

<h3>Answer: 25%</h3>

How do you work in detail the problem below?<br><br> 2x=3x+1
natta225 [31]
2x=3x+1
First, subtract 3x from both sides to get the variable on only one side
-x=1
Now, divide -x by -1 so that it can get rid of the negative sign and so the only thing remaining on the x's side is x.
Your final answer should be: x=-1

A car dealership is having a sale in which customers pay 85% of the retail price for a new vehicle. keith is buying a vehicle wi
mash [69]
First, we calculated the discounted price which would have been paid by Keith. That is the product of 85% and $36,000.
                                      ($36,000) x (85%) = $30,600
Then, after negotiating to pay 9% off the sale price, he will only need to pay 91% of the sale price. The new price would be,
                              ($30600) x (0.91) = $27846
Thus, Keith will only need to pay $27,846.

Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y) = 9 sin(xy), (0, 8)
malfutka [58]

Answer:

The magnitude is  \Delta f(0,8)  =  72

The  direction  is  i i.e toward the x-axis

Step-by-step explanation:

From the question we are told that

   The function is  f(x, y) =  9sin(xy) \ \ \

    The point considered is  (0,8 )

Generally the maximum rate of change of f at the given point and the direction is mathematically represented as

            \Delta f(x,y) =  [\frac{\delta  f(x,y)}{\delta x } i + \frac{\delta  f(x,y)}{\delta y } j  ]

             \Delta f(x,y) =  [\frac{\delta  (9sin(xy))}{\delta x} i  + \frac{\delta  (9sin(xy))}{\delta y} i   ]

            \Delta f(x,y) = [9y cos (x,y) i +  9xcos (x,y) j]

At  (0,8 )

            \Delta  f (0,8) =  [9(8) cos(0* 8)i  + 9(8) sin(0* 8)j  ]

            \Delta  f (0,8) = 72 i

Wrich expreson is equivalent to 4(3-6).​
Korvikt [17]
You haven’t provided any option, however I think I can still help.

You can solve 4(3-6). You first deal with he parenthesis, and get 4(-3). This means that your expression is equivalent to -12.


Hope this helps :)
