If Point P is between Q and R and QP = 16 and Qr = 52. What is the length of PR?

Dimas [21]

1) Here, QR = QP + PR

52 = 16 + PR

PR = 52 - 16 = 36

In short, Your Answer would be Option C

2) Slope of mentioned line:
m = (5+5) / (0-4)
m = 10/-4
m = -5/2

Parallel lines have same slope so it would be -5/2 as well

In short, Your Answer would be Option B

Hope this helps!

441 is 63% of what number

blagie [28]

<span>Question: 441 is 63% of what number?
=> 63% = 63% / 100% = 0.63
Since 441 is the 63% let’s find the value of 37% to get the toal of 100%
Solution, follow the formula
=> 0.63x = 441 – where x will be the value of the missing 100% value.
=> x = 441 / 0.63
=> x = 700 – the 100% value that have 441 as 63%
let’s check if we have the correct answer:
=> 700 * .63 = 441 </span>

What is the valuable of x in the equation 1.8-3.7x=-4.2x+0.3

Mumz [18]

Answer:

x = 3

Step-by-step explanation:

1.8 - 3.7x = -4.2x + 0.3

add -4.2x to both sides

1.8 - 0.5x = 0.3

subtract 1.8 from both sides

-0.5x = 0.3 - 1.8

-0.5x = -1.5

divide by -0.5 on both sides

x = 3

GREAT JOB!!!! YOU GOT IT!!! =)

The function f(x) = −x^2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), i

pychu [463]

Set the function to equal zero:

$-x^2 - 5x + 50 = 0$

To find the zeros, or solutions, to this problem, we will use the quadratic formula:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Plug the values into the equation:

$a = -1, b = -5, c = 50$

$x=\frac{5\pm\sqrt{-5^2-4(-1)(50)}}{2(-1)}$

$x=\frac{5\pm\sqrt{25+200}}{-2}$

$x=\frac{5\pm15}{-2}$

Solve for both plus and minus:

$\frac{5 + 15}{-2} = \frac{20}{-2} = -10$

$\frac{5 - 15}{-2} = \frac{-10}{-2} = 5$

$x = -10, x = 5$

The question cannot use a negative value for x, as the diver cannot dive a negative distance from the board.

The answer is '<span>x = 5; the diver hits the water 5 feet away horizontally from the board', because x represents the horizontal distance away from the board.</span>
