1) First, you would need to create an equation for this problem. Let x represent the unknown percentage.
$\frac{35}{185}$ = $\frac{x}{100}$

Next, you would cross multiply.
185x = 3,500

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 185.
x = 18.918%

Your answer was correct!

2) First, you would need to create an equation for this problem. Let x represent the unknown 85%.
$\frac{x}{190}$ = $\frac{85}{100}$ 

Next, you would cross multiply.
100x = 16150

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100.
x = 161.5

3) First, you would need to create an equation for this problem. Let x represent the unknown percentage.
$\frac{24}{128}$ = $\frac{x}{100}$

Next, you would cross multiply.
128x = 2,400

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 128.
x = 18.75%

I hope this helps!

While eating dinner marian are 25% of the apples slices she had in her bag she ate 5 apple slices in her bag how many apple slic

Studentka2010 [4]

$\text{Hello there!}\\\\\text{We know that 25\% = 5 apples}\\\\\text{We need to multiply by 4 to get to 100\%}\\\\\text{This means we also have to multiply 5 by 4 in order to get the original}\\\text{amount of apples}\\\\5\cdot4=20\\\\\boxed{\text{Marian originally had 20 apples}}$

In equilateral ΔABC, AD, BE, and CF are medians. If FO = 4, then AE = A) 4 B) 4 3 C) 8 D) 12

vampirchik [111]

Firstly, we need to draw triangle

we know that

O is a centroid

and centroid divides median into 2:1

so,

$\frac{CO}{FO} =\frac{2}{1}$

we have FO=4

so, we can plug it

$\frac{CO}{4} =\frac{2}{1}$

$CO=8$

now, we can find CF

CF=OC+FO

CF=8+4

CF=12

now, we can see triangle ACF is a right angled triangle

so, we can use pythagoras theorem

$x^2=(\frac{x}{2} )^2+12^2$

now, we can solve for x

$\frac{3x^2}{4}=144$

$x^2=192$

$x=8\sqrt{3}$

Since, it is equilateral triangle

so,

$AC=x=8\sqrt{3}$

we know that

E is a mid-point

so,

$AE=\frac{AC}{2}$

now, we can plug values

$AE=\frac{8\sqrt{3}}{2}$

$AE=4\sqrt{3}$ ................Answer

Determine if the numerical value describes a population parameter or a sample statistic. 72%72% of all students at the local uni

Korolek [52]

72% of all students at the local university eat out more than twice a week is a population parameter. A population parameter is a value describing the whole population, i.e. all of the objects in it. A sample statistic on the other hand describes only a chosen sample from the population.

If xy + y² = 6, then the value of dy/dx at x= -1 is

mylen [45]

Hi there!

$\large\boxed{\text{At (-1, -2), }\frac{dy}{dx} = -\frac{2}{5}}}$

$\large\boxed{\text{At (-1, 3), }\frac{dy}{dx} = -\frac{3}{5}}}$

We can calculate dy/dx using implicit differentiation:

xy + y² = 6

Differentiate both sides. Remember to use the Product Rule for the "xy" term:

(1)y + x(dy/dx) + 2y(dy/dx) = 0

Move y to the opposite side:

x(dy/dx) + 2y(dy/dx) = -y

Factor out dy/dx:

dy/dx(x + 2y) = -y

Divide both sides by x + 2y:

dy/dx = -y/x + 2y

We need both x and y to find dy/dx, so plug in the given value of x into the original equation:

-1(y) + y² = 6

-y + y² = 6

y² - y - 6 = 0

(y - 3)(y + 2) = 0

Thus, y = -2 and 3.

We can calculate dy/dx at each point:

At y = -2: dy/dx = -(-2) / -1+ 2(-2) = -2/5.

At y = 3: dy/dx = -(3) / -1 + 2(3) = -3/5.
