Answer:

5.414

Step-by-step explanation:

Formula to find circumference is 3.14 x 2r

So we can create a algebraic expression.

3.14 x 2r = 34 / 3.14 = 10.828 / 2 = 5.414

Answer:

j(x) = [ (3/10) cookie/student ]x

Step-by-step explanation:

The "unit rate" here is

3 jumbo cookies

------------------------- = (3/10) cookie/student

10 students

Then the number of cookies needed to feed x students is

j(x) = [ (3/10) cookie/student ]x

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio on right triangle KJL

and the exact value sin30° = $\frac{1}{2}$

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{JL}{KL}$ = $\frac{JL}{8\sqrt{2} }$ = $\frac{1}{2}$ ( cross- multiply )

2JL = 8 $\sqrt{2}$ ( divide both sides by 2 )

JL = 4 $\sqrt{2}$

---------------------------------------------------------

Using the sine ratio in right triangle JLM

and the exact value sin45° = $\frac{1}{\sqrt{2} }$

sin45° = $\frac{opposite}{hypotenude}$ = $\frac{LM}{JL}$ = $\frac{x}{4\sqrt{2} }$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

x × $\sqrt{2}$ = 4 $\sqrt{2}$ ( divide both sides by $\sqrt{2}$

x = 4
