<span>x/900(pi) = 135/360

x = [900pi][135/360] = 337.5(pi) sq ft (area that receives water)
Hope this helps!

Answer:

15 ft

Step-by-step explanation:

The circumference formula is C = 2πr, where we will use 3.14 for pi (not pie) and 94.2 ft:

94.2 ft = 2(3.14)r, or

94.2 ft

----------- = r = 15 ft

2. Jessica's financial advisor believes that she should spend no more than 28% of her gross monthly income for housing. She has

scoray [572]

Jessica's annual salary is $68571.43.

Data;

percentage saved for housing = 28%
amount saved annually = $1600

<h3>Percentage</h3>

This is the ratio of a number to the entire value and multiplied by 100

The percentage set aside for housing is given as 28% which is $1600.

Let find 28% of x which is equal to 1600

$\frac{28}{100} = \frac{1600}{x}$

cross multiply both sides and solve for x

$\frac{28}{100} = \frac{1600}{x}\\ 28*x = 100*1600\\28x = 160000\\$

Divide both sides by the coefficient of x

$\frac{28x}{28} = \frac{160000}{28}\\ x = 5714.28$

Her monthly income is $5714.28.

Let's multiply this by 12 (months in a year) to determine her gross monthly income.

$5714.28*12 = 68571.43$

From the above calculations, Jessica's annual salary is $68571.43.

Which choice shows the image of triangle QRS after the reflection over the x-axis followed by a rotation of 180° around the orig

Alex777 [14]

Answer:

Step-by-step explanation:

We see that triangle QRS is located in Quadrant III. (See attachment for labelling of quadrants)

Reflecting it over the x-axis means that we flip it over the x-axis, or we flip it vertically. Doing so, QRS will end up in Quadrant II.

Now, we need to rotate QRS 180 degrees about the origin. The quadrants are all 90 degrees away from each other, which means that if we rotate QRS about the origin 180 degrees, we'll end up two quadrants away from Quadrant II: we'll end in Quadrant IV.

Look at each of the answer choices. The only choice that features Q'R'S' (the image of QRS) in the fourth quadrant is the first choice, or A. So that's the answer.

The sun shines at a 30° angle to the ground. To the nearest inch, how long is the shadow cast by a 72-in, tall fence post?

Anestetic [448]

The length of the shadow is 124.7 in

<u>Explanation:</u>

Angle of sun to the ground, θ = 30°

Height of the fence, h = 72 in

Length of the shadow, l = ?

We know,

tan θ = (Perpendicular)/(Base)

So,

tan 30° = $\frac{72}{l}$

$\frac{1}{\sqrt{3} } = \frac{72}{l} \\\\l = 72\sqrt{3} \\\\l = 124.7$

Therefore, the length of the shadow is 124.7 in
