Answer:

there monthly budget is $4000

Step-by-step explanation:

if 600 is 15% then there is 85% of there budget left so in order to find how much is 1% then 600/15=40 so $40 = 1% so 1%x100=100% and 40x100=4000 so 100% of there budget is $4000

What is the value of x? Please show the steps

Let D be the endpoint of the angle bisector opposite A on lying on side BC. The angle bisector theorem states that the ratio of BD to CD is equal to the ratio of AB to AC. In this case, you have

$\dfrac{2x-1}{3x}=\dfrac9{15}$

(This is the same equation that you have, it's just rearranged.)

Multiply both sides by $3x$ and 15.

$15\times3x\times\dfrac{2x-1}{3x}=15\times3x\times\dfrac9{15}$
$15(2x-1)=3x\times9$

Now you can solve for $x$ .

$30x-15=27x$
$3x=15$
$x=5$

Amy looks up to the 8-foot basketball hoop as shown. If the vertical distance from the ground to Amy’s eyes is 5.9 feet, what is

Igoryamba

The angle of elevation of an object as seen by an observer is the angle between the horizontal and the line from the object to the observer's eye (the line of sight). since you did give the horizontal distance between amy and the hoop, so let us represent it as x.
so the angle of elevation = tan^-1 ( (8 - 5.9) / x)
angle elevation = tan^-1 ( 2.1 / x )
