BRAINLIEST FOR THE 1ST OR 2ND ANSWER... I'M BEING TIMED Kendra is making cookies. The recipe calls for `6\ \frac{3}{4}` cups flour for 4 batches of cookies. Janel is using the same recipe. She will make b batches of cookies using c cups of flour. Write two equations that represent the relationship between b and c.
Use the table to help guide you. The table will not be provided on the test, so you will need to decide whether to create your own table or not to help you with this problem.
Hints: When you solve for 1 cup of flour in the table, the number of batches you get, b, is the constant of proportionality. If you know the constant of proportionality, then you should be able to write an equation. As tempting as it is to use the calculator on this problem, it will actually be easier if you use fractions.
b = _ c
You can then write a second equation by reversing the variables and using the reciprocal.
c = _ b

the value of x is 9 ⇒ answer b

step-by-step explanation:

* we can solve this problem using cosine and sine rule

- in δ abc

∵ ab = 36 , bc = 28 , ac = 16

- lets find the measure of angle b using the cosine rule

∵ cos b = [ab² + bc² - ac²]/2(ab)(bc)

∴ cos b = [36² + 28² - 16²]/2(36)(28)

∴ cos b = 19/21

∴ m∠b = cos^-1(19/21) ≅ 25°

- lets find the measure of angle a using the sine rule

∵ sina/bc = sinb/ac = sinc/ab

∴ sina/28 = sin25°/16 ⇒ by using cross multiplication

∴ sina = 28 × sin25°/16

∴ sina = 0.7396

∴ m∠a = sin^-1(0.7396) ≅ 48°

- from the figure m∠abd = m∠dbc

∵ m∠abc = 25°

∴ m∠abd = 25°/2 = 12.5°

- in δabd

∵ m∠a = 48° , m∠abd = 12.5°

∵ the sum of the measures of the interior angles of any δ is 180°

∴ m∠adb = 180° - (48° + 12.5°) = 119.5°

∵ ab = 36

∵ ad = x

- use the sine rule to find x

∵ sin∠adb/ab = sin∠abd/x

∴ sin119.5°/36 = sin12.5°/x ⇒ by using cross multiplication

∴ x = 36 × sin12.5°/sin119.5° = 8.95 ≅ 9

* the value of x is 9

the correct answers are 1, 2, 4, and 5! i just got it right!
