The lesson is 19.2 Angles in inscribed Quadrilaterals

alexdok [17]

Answer:

m<R=44.9,m<S=56.9,m<T=44.9,m<U= 32.9.

Step-by-step explanation:

When two chords are equal then the measure of the arcs are equal.

Chord RU= Chord UT

Or , m arc RU= m arc UT,

3z-4=x+2z+7 Or z=x+11

Chord RS=Chord ST ,

m arc RS=m arc ST=3x+5

Sum of m arc in a circle =360 degrees.

Or ,

3x+5+3x+5+3z-4+x+2z+7=360

7x+5z+13=360

Substituting z=x+11

7x+5(x+11)+13=360

7x+5x+55+13=360

12x+68=360

12x=292,x=24.3

z=x+11=11+24.3=34.3

m arc RU=marc UT= 3z-4=3(24.3)-4=69

m arc RS =marc ST= 3x+5=3(24..3)+5=77.9

m<R= (marc UT+ m arc ST)÷2

m<R=(69+77.9)÷2=73.45

m<S= (m arc RU+m arc UT)÷2

m<S= (69+69)÷2=69

m<T=(m arc RU+m arc RS)÷2=73.45

m<U=(m arc RS+m arc m arc ST)÷2=77.9

To find the weight of the gold in a 22 karat gold object,multiply the object's weight by 0.917.To find the weight of the gold in

gogolik [260]

Answer: 22 karat gold statue contains more gold than 14 karat gold statue by $4.23-2.68=1.55\ pounds$ .

Step-by-step explanation:

Since we have given that

There is 22 karat gold statue weighing 73.5 ounces,

So, weight of the gold in gold statue is given by

$73.5\times 0.917=67.4\ ounces$

There is 14 karat gold statue weighing 73.5 ounces,

So, weight of the gold in gold statue is given by

$73.5\times 0.583=42.85\ ounces$

As we know that

$1\ pound =16\ ounces$

So, 22 karat gold statue has

$\frac{67.4}{16}=4.23\ pounds\ of\ gold$

And, 14 karat of gold statue has

$\frac{42.85}{16}=\ pounds\ of\ gold$

Hence, 22 karat gold statue contains more gold than 14 karat gold statue by $4.23-2.68=1.55\ pounds$ .

Jana joined a music club that offered her 5 CDs for a total of 3.00 if she agreed to purchase an additional 10 CDs for 15.00 eac

Hunter-Best [27]

Answer:

Average price, excluding taxes, for each CD is <u>10.20</u>.

Step-by-step explanation:

Given:

Cost of first 5 CDs, $C_1 = 3.00$

Cost of each additional CD = 15.00

Now, cost of 10 additional CDs is the product of cost of one CD and total number of additional CDs. Therefore,

Cost of 10 additional CDs is, $C_2=15.00\times 10=150.00$

Now, total CDs purchased by Jana are, $N=5+10=15$

Total cost of the 15 CDs purchased is given as:

$C_T=C_1+C_2=3.00+150.00=153.00$

Now, average price, excluding taxes, for each CD is given as:

$\textrm{Average price}=\frac{\textrm{Total cost of purchase}}{\textrm{Total number of CDs purchased}}\\\\\textrm{Average price}=\frac{C_T}{N}=\frac{153.00}{15}=10.20$

Therefore, the average price, excluding taxes, for each CD is 10.20.
