Answer:

the answer is 12 attendees

Step-by-step explanation:

Let a=the attendees & Let d=the cost

if the budget is $97 and the cost of the gala is represented by the equation d=7a+13, substitute the $97 for d

d=7a+13

97=7a+13

now take subtract 13 from both sides

97-13=7a+13-13

since the 13 cancels out on the right side it'll now read:

84=7a

to get a by itself you now divide 7 from both sides getting a by itself

84/7=7a/7

12=a

so the answer will be 12

Answer:

58.61%

Step-by-step explanation:

Your total backyard is 18ft * 9ft = 162 ft^2

Your patio is 5ft * 8ft = 40 ft^2

Your Garden is 4ft * 7ft = 28 ft^2

Your walkway is 3ft * 9ft = 27 ft^2

Add all those areas together you have 95 ft^2

95 of 162 = 58.61%

Step-by-step explanation:

If you don't understand some steps, comment it for me please.

1. Find diagonal.

d = 2r

d = 2(9)

d = 18

2. Find length of square.

each length of square = x

$x : 18 = 1 : \sqrt{2}$

$\frac{x}{18} = \frac{1}{\sqrt{2} }$

$\sqrt{2}x = 18$

$x = \frac{18}{\sqrt{2} } = 9\sqrt{2}$

3. Find area of circle and square.

Area for circle

$A = \pi r^2$

$A = \pi (9)^2$

$A = 81\pi = 254.4690...$

Area for square

$A = (length)^2$

$A = (9\sqrt{2})^2$

$A = 162$

4. Subtract area of circle to area of square.

254.4690... - 162 = 92.4690...

5. Find the shaded region.

92.4690... / 4 = 23.1172...

Rounded to the nearest hundredth = 23.12

The product of two number is 1575 and their quotient is 9/2 find the number

Otrada [13]

(1) p x q = 1575
(2) p / q = 9 / 2
divide 1 by 2 to eliminate p:
q^2 = 1575 / (9/2)
q^2 = 350
q = sqrt(350)

Substitue q in either 1 or 2 to find p.
