Please help me! I'm having trouble solving this! In the △PQR, PQ = 39 in, PR = 17 in, and the height PN = 15 in. Find QR. Consider all possible cases.

Answers

Answer: 44

Step-by-step explanation:

we will find RN and NQ, then add together to give us RQ.

To find RN;

RP= 17 PN = 15 and RN =?

using pythagoras theorem,

adj^2 = hyp^2 - opp^2

RN^2 = RP^2 - PN^2

?^2 = 17^2 - 15^2

?^2 = 289 - 225

?^2 = 64

? = √64

? = 8

RN=8

To find NQ,

PN = 15 PQ=39 and NQ=?

using pythagoras theorem

NQ^2 = PQ^2 - PN^2

?^2 = 39^2 - 15^2

?^2 = 1521 - 225

?^2 = 1296

? = √1296

? = 36

NQ= 36

RQ = RN + NQ

RQ= 8 + 36

RQ=44

Line segment AB measures 18 unit

Answers

Answer: The correct option is (B) 2 units.

Step-by-step explanation: Given that the length of the line segment AB is 18 units.

We are to find the value of d, the distance between the tick marks on the number line.

From the figure, we note that

the line AB is divided into nine equal segments and one of them measures d units.

So, we must have

$d*9=AB\n\n\Rightarrow 9d=18\n\n\Rightarrow d=(18)/(9)\n\n\Rightarrow d=2.$

Thus, the value of d is 2 units.

Option (B) is CORRECT.

d, the distance between thick marks on the number line is 2 units.

1 5/6 divided by 2 1/8 by writing it out to solve the problem. STEP BY STEP

Answers

1 5/6 divided by 2 1/8
1) you must change the mixed numbers into improper fractions
2) 1 5/6 is 11/6 and 2 1/8 is 17/8
3) then you must change the operation from division to multiplication
4) then you have to find the recipricol of 17/8 (flip it) and it will be 8/17
5) Finally, you multiply and you will get 88/102: 11/6x8/17=88/102 amd yoy can simplify if asked

Final answer:

To solve 1 5/6 divided by 2 1/8, convert each number into an improper fraction, reciprocate the second fraction and multiply it with the first. The result is 8/6 which simplifies to 1 1/3.

Explanation:

To solve the problem of 1 5/6 divided by 2 1/8, we should first convert each mixed number into an improper fraction. The number 1 5/6 becomes 17/6 (because 1*6 + 5 = 11) and 2 1/8 becomes 17/8 (because 2*8 + 1 = 17). Then we transform the division into multiplication by using the reciprocal of the second fraction. This makes the problem 17/6 multiplied by 8/17. These two fractions multiply to simplifying to 1, leaving us with the answer of 8/6, which can be simplified to 1 1/3.
