Using the tangent theorem and the inscribed angle theorem, we have:

a. m∠SQT = 74°; b. m∠RQS = 16°.

Angle formed at the point of tangency between the tangent and the radius of a circle = 90 degrees based on the tangent theorem.

The inscribed angle theorem states that, measure of inscribed angle = 1/2(measure of intercepted arc).

a. Find m(SQT):

m∠RQT = 90° [tangent theorem]

m(QR) = 180° [semicircle]

m(QRS) = 212° [given]

m(RS) = m(QRS) - m(QR) = 212 - 180 = 32°

m∠RQS = 1/2[m(RS)] [inscribed angle theorem]

m∠RQS = 1/2(32)

m∠RQS = 16°

m∠SQT = m∠RQT - m∠RQS = 90 - 16

m∠SQT = 74°

b. m∠RQS = 1/2(32)

m∠RQS = 16°

Answer:

C. 1/3.

Step-by-step explanation:

There are 2 favourable outcomes:

a 5 or a 6.

So that is 2 numbers out of 6.

Therefore the probability is 2/6

= 1/3.

Answer:

The system of equation has infinite solution.

Step-by-step explanation

2x + y = 3

6x = 9 – 3y

First we re-write the second equation in standard form

So, we add 3y both sides

6x+3y=9 ---------------- (2)

2x+y = 3-----------------  (1)

3(2x)+3y = 3(3)

6x+3y=9

6x-6x + 3y-3y = 9-9

0=0

LHS=RHS

Using it's concept, it is found that the probability that a person who is above 35 years old has a hemoglobin level of 9 or above is of 0.247.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching the problem on the internet, we find a table, which says that there are 162 participants above 35 years old, and 40 have hemoglobin levels of 9 and above, hence the probability is given by:

p = 40/162 = 0.247.

Answer:

The total price David paid for the computer is $933.12

Step-by-step explanation:

The cost of the computer will be $1,080 with 20% off and 8% sales tax.

20% of 1080 is 1080(0.20)=216 this means 216 is 20% of 1080, so with the discount the price will be 1080-216=$864

Now we have to find 8% of 864.

864(0.08)=$69.12

So the total price will be 864+69.12= $933.12

(y³ - 2) (x² - 2).

Step-by-step explanation:

x²y³ - 2y³ - 2x² + 4

= y³ (x² - 2) - 2(x² - 2)

(x² - 2) is common to both parts so we have:

(y³ - 2) (x² - 2)

Step-by-step explanation:

the surface area consists of 6 individual areas :

front and back (both are equal)

left and right (both are equal)

top and bottom

front and back are trapezoids.

the area of a trapezoid is

(base 1 + base 2)/2 × h

the bases are the 2 parallel sides.

in our case the area of one trapezoid is

(5 + 19)/2 × 12.1 = 145.2 ft²

front and back together then are 290.4 ft².

left and right are 8×14 rectangles:

8×14 = 112 ft²

together they are 224 ft².

the bottom is a 5×8 rectangle :

5×8 = 40 ft²

the top is a 19×8 rectangle :

19×8 = 152 ft²

so, the total surface area is

290.4 + 224 + 40 + 152 = 706.4 ft²

Explanation

Step-by-step explanation

Here ...I'm not too sure about the question as you have written

P = 2 ( 1 + 6 ) and ask to solve for L ...

.So I guess the question you have written is wrong .. ...and I guess there should be L in the place of 1.

...So let me correct the question....

P = 2 ( l + 6 )

P = 2l + 12

P - 2l = 12

- 2l = 12 - P

- 2l = - P + 12

Change the sign of both side of the equation...

2l = P + 12

divide both side by the same number...

L = ( P + 12 ) ÷ 2

[tex]l = \frac{1}{2} p - 12 \times \frac{1}{2} \\ [/tex]

Calculate the product of rational numbers...

[tex]l = \frac{1}{2} p - 6 \\ [/tex]
