Answer: x = 9

Step-by-step explanation:

9/x = x/16

y^2 + 16^2 = 49

root 16^3= 16 - y

square root 49 = 7

y is the variable for this example

16 - y = 16 - 7 because y = 7

16 - 7 = 9

x = 9

What is the distance between the two points (5,-2) and (-3,8)

bearhunter [10]

You need to use the distance formula
$d = \sqrt{ {(x - x)}^{2} + {(y - y)}^{2} }$

$\sqrt{ {(5 + 3)}^{2} + {( - 2 - 8)}^{2} }$
so the distance between points (5,-2) and (-3,8) is
$2 \sqrt{41}$
which won't simplify so it stays as is

Two grandparents want to pick up the mess that their granddaughter had made in her playroom. One can do it in 15 minutes working

Crank

Answer:

6 2/3 minutes

Step-by-step explanation:

Their rates in "jobs per hour" are ...

(60 min/h)/(15 min/job) = 4 jobs/h

and

(60 min/h)/(12 min/job) = 5 jobs/h

So, their combined rate is ...

(4 jobs/h) + (5 jobs/h) = 9 jobs/h

The time required (in minutes) is ...

(60 min/h)/(9 jobs/h) = (60/9) min = 6 2/3 min

Working together, it will take them 6 2/3 minutes.
