What is the length of PQ round to the nearest tenth of a unit p(-3 ,7) q(6 ,1)

Answers

Answer 1

Answer:

Answer: The approximate length of PQ is 10.8 unit.

Step-by-step explanation:

Here the coordinates of point P are (-3,7) and the coordinates of Q are (6,1)

Thus, by the distance formula,

The distance between the points P and Q is,

$PQ = √((6-(-3))^2+(1-7)^2)$

$=\sqrt{(6+3)^2+(-6)^2$

$=√(9^2+ 36)$

$=√(81+36)=√(117)=10.8166538264\approx 10.8$

Thus, the approximate length of PQ is 10.8 unit.

On June 8,1999, the national debt of the U.s.a was about $5,608,000,000,000.the population of the United states at the time was about 273,000,000.Suppose the national debt was divided evenly among everyone in the U.S,how much would each person owe ?

Answers

To figure out the answer, you must divide the debt by the population.

$(5,608,000,000,000)/(273,000,000) =20,542.12$

Each person would owe $20,542.12.

What is the sales rate for 5% of $50

Answers

well 5 is a percentage, so it goes over 100. soo its would be like 5%/100% and the 50$ is like the 100% except its not a percentage.. so it would be ... x/50

So from here, you cross multiply,so 5 times 50 equals 250
Now You have to divide 250 by 100
So your answer is: 2.5 OR 2.50

speed divided by time
per hour means per 1 hour
so we do

9.66/4.2=2.3/1

answer is 2.3 miles per hour

3. IF ON = 5x - 7, LM = 4x +4, NM = x - 7, and OL = 3y – 4, find the values of x and y for which LMNO mustbe a parallelogram. The diagram is not to scale.
N CH-7=5X

Answers

Answer:

x = 11 and $y = (8)/(3)$

Step-by-step explanation:

If LMNO is a parallelogram then it's opposite sides will be equal.

So, LM = ON

⇒ 4x + 4 = 5x - 7

⇒ x = 11

Now, MN = OL

⇒ x - 7 = 3y - 4

⇒ 11 - 7 = 3y - 4 {Since we already have, x = 11}

⇒ $y = (8)/(3)$ (Answer)
