17=5k-2 what Is (k) help me please

Answers

Answer 1

Answer: 17=5k-2
add 2 to both sides
19=5k
divide both sides by 5
3.8=k

Answer=3.8

Answer 2

Answer: 17=5k-2
add 2 to both sides
19=5k
divide both sides by 5
19/5=k
19/5=3 and 4/5

If arc AD = 130° and arc AB = arc CD = 80°, what is the measure of ∠APD?

Answers

Answer:

(B)

Step-by-step explanation:

Given: It is given that arc AD=130° and arc AB=arc CD=80°.

To find: The measure of ∠APD.

Solution: It is given that arc AD=130°⇒m∠AOD=130° (The measure of the central angel is equal to the intercepted arc)

Also, arc AB=arc CD=80°⇒m∠AOB=m∠DOC=80° (The measure of the central angel is equal to the intercepted arc)

We know that the sum of the central angles is equal to 360°, thus

m∠AOD+m∠AOB+m∠BOC+m∠COD=360°

⇒130°+80°+m∠BOC+80°=360°

⇒290°+m∠BOC=360°

⇒m∠BOC=360°-290°

⇒m∠BOC=70°

Now, since (The measure of the central angel is equal to the intercepted arc), therefore arcBC=70°.

Also, we know that Angle Formed by Two Secants is half of the DIFFERENCE of Intercepted Arcs, therefore

$m{\angle}APD=(1)/(2) (arcAD-arBC)$

Substituting the values, we get

$m{\angle}APD=(1)/(2) (130-70)$

⇒ $m{\angle}APD=(60)/(2)$

⇒ $m{\angle}APD=30^(\circ)$

Thus, the measure of ∠APD is 30°.

Hence, option B is correct.

the answer is 25

What is 59424.77 square miles rounded to the nearest square mile

Answers

The next larger square mile is 59,425 .
The next smaller square mile is 59,424 .
59,424.77 is closer to 59,425 than it is to 59,424.
So the nearest square mile is 59,425 of them.

Answers

1. 150* .40 = 60 so 150 -60 = 90 so the markdown price is $90

2. 18.99*.25 =4.75 (rounded ) so 18.99-4.75 is $14.24 as your markdown price

3. 95 * .10= 9.5 so 95- 9.5 = $85.50 as your markdown price

4. 75*.15=11.25 so 75-11.25=$63.75 as your markdown price

Answer:

1. 150* .40 = 60 so 150 -60 = 90 so the markdown price is $90

2. 18.99*.25 =4.75 (rounded ) so 18.99-4.75 is $14.24 as your markdown price

3. 95 * .10= 9.5 so 95- 9.5 = $85.50 as your markdown price
