First choose 1 equation and set it equal to 180 because supplementary angles equal up to 180 degrees. 

12q - 9 =180                                                              

Now solve for q.

12q - 9 +9 = 180 + 9

12q = 189

12q/12 = 18912

q = 15.75

now subtract 15.75 from 180

180.00 - 15.75 = 164.25

Your angles equal to 164.25 and 15.75 degrees.

Braxton loves downloading new music he originally had 41 songs but plans to purchase 4 new songs each week. he wants to know how
ycow [4]

Answer:

a_110=41+(110-1)4

Step-by-step explanation:

He already has songs = 41

Since we are given that he purchase four songs every week .

So, in first week he purchase songs = 4

Initially he already has 41 songs

So, total songs after 1 week = 41+(4\times1)=45

After 2 weeks he will have songs = 41+(4\times 2)=49

This forms an arithmetic sequence  : 41,45,49......

Formula of nth term in A.P. : a_n=a+(n-1)d

a = first term = 41

d = common difference = 45-41=49-45=4

Since we are required to find the new songs after110 weeks

So, n =110

Substituting values :

a_110=41+(110-1)4

Thus Option A is correct.

Using the approximation 3.14 for \pi what is the radius of a circle with circumference 44m
Feliz [49]

Answer:

7 m

Step-by-step explanation:

Circumference of a circle uses the formula;

Circumference = 2 × pi × radius(r)

If the circumference = 44

then we use the formula above to calculate the value of the radius,

44 = 2 × pi × r...then divide both sides by (2 × pi(3.14))

Radius = 44 ÷ ( 3.14 × 2)

;Radius = 7.01

;Radius = 7m

Hi i need help with 15a(ii)
Art [367]

Answer:

x = 5/2

Step-by-step explanation:

log4(x^2+5x)-log8(x^3)=1/log3(4)

log(x^2 + 5 x) / log(4) - log(x^3) / log(8) = log(3) / log(4)

log(x (x+5))/log(4) - log(x^3) / log(8) = log(3) / log(4)

(3 log(x (x+5)) - 2 log(x^3)) / log(64) = log(3) / log(4)

3 log(x (x+5)) - 2 log(x^3) = 3 log(3)

log((3 x)/(x+5))=0

x=5/2
