Im giving out 15 free points plus brainliest for correct answer !

examine the algebraic expression below.

1/3 r + 2

which scenario could this expression represent?
jacob’s rate is 3 times marc’s rate plus 2.
jacob’s rate is two more than 3 times marc’s rate.
jacob’s rate is two more than one-third marc’s rate.
jacob’s rate is two less than one-third marc’s rate.

The answer to your question is: third option is correct.

Step-by-step explanation:

The correct answer is: Jacob's rate is two more than one-third Marc's rate.

First option is:  3r + 2

Second option is: 2 + 3r

Fourth option: 1/3 r - 2

Jacob's rate is two more than one-third of Marc's rate.  

Step-by-step explanation:

Let's rewrite the expression as  

y = 2 + ⅓r  

Now convert it to a word expression

y  =   2           +                ⅓         r  

↑ ↑   ↑           ↑                 ↑        ↑

y is two (more than) (one-third) r.

Replace y with "Jacob's rate" and r with "Marc's rate", and the expression becomes

Jacob's rate is two more than one-third Marc's rate.

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
