The figure shows the construction of a line tangent to a circle from a point on the circle. From the diagram, which statement is true?
1. OP ≈ QR
2. P is the midpoint of OR
3. OQ+QP=QP + PR
4. PQ≈ PR
The required statement that is true for the given circle is PQ = PR. Option D is correct.
What is a circle?A circle is a closed shape consisting of all points in a plane that are at a constant distance from a single fixed point called the center. The distance between the center and any point on the circle is called the radius, and the distance across the circle, passing through the center, is called the diameter.
Here,
From the figure,
QP = PR,
So P is the midpoint of QR,
Thus, the required statement that is true is PQ = PR. Option D is correct.

Jen traveled from Boston to Cape Cod at 60 mph. On her way back, the
traffic was bad and her return trip took 3 times as long. What was Jen's
average speed on the round trip?
Answer: 30 mph
Step-by-step explanation: As we know: the formula for Average Speed (AS) is Average Speed = Total Distance ÷ Total Time.
Since we don't know exactly how far Jen needed to drive, our distance there will be 1, and since we don't know how long it took to get there, we will put 1 as well.
Now we have to state the distance and time to get back. The distance will stay the same so we keep it 1. Now it is stated that when returning, it took Jen 3 times slower to get back, so we do 1 × 3 (because it took her longer) and get 3.
Next, we substitute: AS=TD÷TT ⇒ AS= (1+1) ÷ (1+3) = 2 ÷ 4= 1/2 or 1.4
Since our given beginning speed was 60mph, we need to multiply by 1/2 to get the final answer:
1/2 x 60 = 30
So ya, this is the answer *100% correct, checked on another website*

The line L1 is defined Ax + By = 3. The line L2 is defined by the equation Ax + By = 2. The line
L3 is defined by Bx − Ay = 1. Determine whether L1, L2 and L3 are parallel or perpendicular to each other.
Step-by-step explanation:
Line 1: Ax+By=3
By=-Ax+3
-> slope is -A/B
Line 2: Ax+By=2
By=-Ax+2
-> slope is -A/B
Line 3: Bx-Ay=1
Ay=Bx-1
-> slope is B/A
So lines 1,2 are parallel, and lines 1,3 and 2,3 are perpendicular
Cereal is on sale this week. Is it a better buy to get the 10-ounce box for $1.86 or the 14-ounce box for $2.61?

Jane and Eric are helping their teacher buy supplies for a research project. Every student will get a bag with 2 pencils and 30 index cards.
The teacher gave Jane $17 to buy pencils from the school store. The pencils come in boxes of 12 and cost $1.69 per box.
Eric was given $19 to buy index cards at an office supply store. Index cards are sold in packs of 150 cards and cost $2.99 per pack.
Jane buys as many boxes of pencils as she can afford. Eric buys as many packages of index cards as he can afford. How many complete bags of supplies can they make?
Answer:
They can make 30 Bags total.
Step-by-step explanation:
Jane has $17. There are 12 pencils in each pack for $1.60.
Jane can bay 10 packs of 12 pencils for $16.9 or else she will go over the amount of money she has.
1.69 x 10 = 16.9
Eric has $19. There are 150 cards in one pack for $2.99.
Eric can bay 6 packs of 150 cards for $17.94 or he ill go over the amount of money he has.
2.99 x 6 = 17.94
Eric.
150^6 = 900
900/30 = 30
Jane.
12^10 = 120
120/2 = 60
60/2 = 30
Together.
30 cards can go into 30 bags, and 2 pencils can go into 30 bags
Add 1/6 +3/4 + 2/3. Simplify the answer and write it as a mixed number, if possible.
Answer:
1 7/12
Step-by-step explanation:
Answer:
1 7/12
Step-by-step explanation:
Firstly, I'm not a native speaker, nor do we do mathematics in English but I'll explain it as I could possibly
Let all the denominators be 12, so multiplying 1/6 with 2, becomes 2/12
3/4 becomes 9/12 (multiplying with 3)
2/3 becomes 8/12
Adding them you get 19/12,
after you divide 19 by 12, the remaining is 7,
so as in mixed numbers, it's 1 7/12.

Step-by-step explanation:
On many cell phones with GPS, an approximate location can be given before the GPS signal is received. This is done by a process called triangulation, which works by using the distance from two known points. Suppose there are two cell phone towers within range of you, located 6000 feet apart along a straight highway that runs east to west, and you know you are north of the highway. Based on the signal delay, it can be determined you are 5050 feet from the first tower, and 2420 feet from the second. Determine the angle, , between your line of sight to the first tower and the highway to the nearest tenth of a degree. (A calculator is needed for this question)

tax, $74 FICA, and $41 state tax. The carpenter's take-home pay is
Answer:
762
Step-by-step explanation:
Since he makes 24 dollars a hour and he worked for a total of 40 hours that'll equal to 960 and when you subtract all the taxes away from his payment it'll equal to 762
The net income of the carpenter will be $762.

The amount paid by any company or industry to the employees after deductions of the several taxes is the net income.
Given that:-
A carpenter makes $24/hour and works a 40 hour week.The deductions are $83 federal tax, $74 FICA, and $41 state tax.So the net income of the carpenter will be calculated as:-
Gross pay will be = 24 x 40 = $960
Net income = 960 - ( 83 + 74 + 41 ) = $762
Hence the net income of the carpenter will be $762.

Complete the equation that represents the relationship between n and s.
Answer: s=n+6
Step-by-step explanation:
We know that s increases by 1 every time n increases by 1.
So we have s = n + [something]
To find this [something], we can just substitute one pair of values.
Take n=1, s=7 - we'll get 7 = 1 + [something] -> [something] = 6
So we have s = n+6

1.Spooky has a favourite number. It is a 2 digit number. The total of the digits is 10. It is an even number It is less than 30. What is it? .........
Answer:
10
Step-by-step explanation:
Even numbers less than 30 are:
2,4,6,8,10,12,14,16,18,20,22,24,26,28
We know it has two digits so we can cross out:
2,4,6,8
We are left with the last piece of information being that it's total is 10 - none of the remaining numbers add up / total to 10 therefore Spooky's favourite number is 10 !
