Answer:

  8700 cubic inches, about 37.66 gallons

Step-by-step explanation:

The volume of a rectilinear space is the product of its length, width, and height. So, the volume of the tank is ...

  V = L·W·H

  V = (60 in)(14 1/2 in)(15 in) = 13050 in³

Since the tank is 2/3 filled, the volume of the water is ...

  water volume = (2/3)V = 2/3 × 13,050 in³ = 8,700 in³

_____

There are 231 in³ in a gallon, so the number of gallons of water in the tank is ...

  (8700 in³)/(231 in³/gal) ≈ 37.66 gal

Let
x-------> the width of the rectangular area
y------> the length of the rectangular area

we know that
y=x+15------> equation 1
perimeter of a rectangle=2*[x+y]
2x+2y <= 150-------> equation 2

substitute 1 in 2
2x+2*[x+15] <=150--------> 2x+2x+30 <=150----> 4x <=150-30
4x <= 120---------> x <= 30
the width of the rectangular area is at most 30 ft
y=x+15
for x=30
y=30+15------> y=45
 the length of the rectangular area is at most 45 ft

see the attached figure
the solution is<span> the shaded area</span>

Dan draws a circle with a radius of 8 inches. Question 1 Part A: What is the circumference of Dan's circle, inches? If needed, r
geniusboy [140]

Answer:

The circumference of Dan's circle is approximately 50.27 inches.

Step-by-step explanation:

The length of the circumference (s), measured in inches, is determined by the formula:

s = 2\pi\cdot r (1)

Where r is the radius, measured in inches.

If we know that r = 8\,in, then the length of the circumference is:

s = 2\pi\cdot (8\,in)

s \approx 50.27\,in

The circumference of Dan's circle is approximately 50.27 inches.
