Answer:

b = 30 / a

which agrees with the third expression in the list of possible options

Step-by-step explanation:

When we say that a and b vary inversely, that means that in mathematical form:

b = k / a where "k" is the so called "constant of proportionality". In order to write the function that models this inverse variation, we need to find the value of "k". We do such by using the information they provide (b = 5/2 when a = 12):

5/2 = k / 12

Then, solving for "k":

5 * 12 / 2 = k

60 / 2 = k

k = 30

Then we can now write the function that models this inverse variation:

b = k / a

b = 30 / a

4. As line SU and TV are intersecting each other at O.

A.T.Q, ∠UOV = (7x - 4)°

∠SOT = 87°

Then, ∠UOV = ∠SOT {Vertically Opposite Angles}

$\rightarrow\sf{7x - 4=87}$

$\rightarrow\sf{7x =87+4}$

$\rightarrow\sf{7x =91}$

$\rightarrow\sf{x =\frac{91}{7}}$

$\rightarrow\boxed{\bf{x =13}}$

5. radius = 17ft

circumference of circle = 2πr

$\rightarrow\sf{circumference=2\times\frac{22}{7}\times17}$

$\rightarrow\boxed{\bf{circumference=106.8ft}}$

3. ∠1 and ∠2 - add to 180 (linear pair)

∠1 and ∠3 - equal (Vertically Opposite Angles)

∠3 and ∠4 - add to 180 (linear pair)

∠2 and ∠4 - equal (Vertically Opposite Angles)

_______________________________________

2. 160° + (6x - 16)° = 180° (linear pair)

$\rightarrow\sf{6x - 16 = 180-160}$

$\rightarrow\sf{6x - 16 = 20}$

$\rightarrow\sf{6x = 20+16}$

$\rightarrow\sf{6x =36}$

$\rightarrow\sf{x =\frac{36}{6}}$

$\rightarrow\boxed{\bf{x =6}}$

Express 72 as a product of its prime factors.

ASHA 777 [7]

The trick is to just keep factoring out 2 until you get all prime numbers.

72 = 36 * 2
36 = 18 * 2
18 = 9 * 2
9 = 3 * 3

Therefore, the answer is:
72 = 2 * 2 * 2 * 3 * 3

Hope this helps

Consider the point (-6,3) and line L: 4x-3y=5. Write an equation (a) for the line passing through this point and parallel to L,

Kobotan [32]

4x - 3y =5

3y = 4x - 5

y = 4/3 x - 5/3

Equation of the line passing through the point (-6,3) and parallel to L

a) Parallel lines have same slope so slope = 4/3

y - 3 = 4/3(x + 6)

y - 3 = 4/3 x + 8

y = 4/3 x + 11

Answer:

Equation y = 4/3 x + 11

b) Perpendicular lines, slope is opposite and reciprocal so slope = -3/4

y - 3 = -3/4 (x + 6)

y - 3 = -3/4 x - 4.5

y = -3/4 x - 1.5

Answer:

Equation y = -3/4 x - 1.5
