It’s True.. you take the “extreme” variable from each proportion and cross multiply them before setting them equal to the product of the two “means” (which are just the other 2 numbers in the proportions).

Given: ∆AKM, R = 2, m∠A = 33°, O∈ AM . Find: perimeter of ∆AKM
Gwar [14]

Answer:

∆AKM is a right triangle for it is inscribed in semicircle O.

AM = diameter of semi-circle O = 2R = 2(2) = 4

%22AK%22%2F%22AM%22=cos%2833%5Eo%29

AK+=+AM%2Acos%2833%5Eo%29

AK+=+4cos%2833%5Eo%29

%22KM%22%2F%22AM%22=sin%2833%5Eo%29

KM+=+AM%2Asin%2833%5Eo%29

KM+=+4sin%2833%5Eo%29

The perimeter of a triangle is the sum of the three sides.

perimeter=AK%2BKM%2BAM

perimeter=4cos%2833%5Eo%29%2B4sin%2833%5Eo%29%2B4

1/3k+80=1/2k+120 k=??
Sati [7]

Answer:

The value of k is 240

Step-by-step explanation:

\frac{1}{3}k + 80 = \frac{1}{2}k + 120

Or, 120 - 80 =  \frac{k}{2} - \frac{k}{3}

Or, 40 = \frac{k}{6}

So. k = 40 × 6  = 240

Hence The value of k is 240   Answer

Sara sells homemade blueberry jelly (b) and strawberry jam (s) at the farmer's market. It is the end of berry picking season, so
Diano4ka-milaya [45]

System of inequalities representing given scenario is as follows

x + y ≤40  

5x + 4y ≥ 120    

<h3><u>Solution:</u></h3>

Given that Sara sells homemade blueberry jelly (b) and strawberry jam (s) at the farmer's market. She has enough berries for no more than 40 jars.

The blueberry jelly sells for $5 per jar,  

And the strawberry jam sells for $4 per jar.

Sara's goal is to make at least $120

Need to write system of inequalities for above scenario.

Let’s assume number of jars of blueberry jelly be represented by variable “x”

And assume number of jars of strawberry jam be represented by variable “y”

<em><u>Let’s create first inequality  </u></em>

As it is given that Sara has enough berries for no more than 40 jars, so total number of jars cannot be more than 40.  

=> Number jars of blueberry jelly + number of jars of strawberry jam ≤40

=>  x + y ≤ 40 ------(1)

<em><u>Now let’s create second inequality </u></em>

Selling Price of 1 blueberry jelly = $5  

So Selling Price of "x" blueberry jelly =x \times 5=5 x

Selling Price of 1 strawberry jam = $4

So Selling Price of "y" strawberry jam = \$ 4 \times \mathrm{y}=4 y

So amount generated by selling x blueberry jelly and y strawberry jam = 5x + 4y

And as Sara’s goal is to generate at least $120, so amount generated by selling “x” blueberry jelly and “y” strawberry jam must be greater than $120  

=> 5x + 4y ≥ 120   ------ (2)

Hence system of inequalities representing given scenario is as follows :

x + y ≤40  

5x + 4y ≥ 120
