A company plans to enclose three parallel rectangular areas for sorting returned goods. The three areas are within one large rec
Svetlanka [38]

Answer:

The largest total area that can be enclosed will be a square of length 272 yards.

Step-by-step explanation:

First we get the perimeter of the large rectangular enclosure.

Perimeter of a rectangle =2(l + w)

Perimeter of the large rectangular enclosure= 1088 yard

Therefore:

2(L+W)=1088

The region inside the fence is the area

Area: A = LW

We need to solve the perimeter formula for either the length or width.

2L+ 2W= 1088 yd

2W= 1088– 2L

W = \frac{1088-2L}{2}

W = 544–L

Now substitute W = 544–L into the area formula

A = LW

A = L(544 – L)

A = 544L–L²

Since A is a quadratic expression, we re-write the expression with the exponents in descending order.

A = –L²+544L

Next, we look for the value of the x coordinate

L= -\frac{b}{2a}

L= -\frac{544}{2X-1}

L=272 yards

Plugging L=272 yards into the calculation for area:

A = –L²+544L

A(272)=-272²+544(272)

=73984 square yards

Thus the largest area that could be encompassed would be a square where each side has a length of 272 yards and a width of:

W = 544 – L

= 544 – 272

= 272 yards

a water sprinkler sends water out in in a circle .how large is the watered area if the the watering Patten is 23 ft
Dennis_Churaev [7]
I'm guessing you're saying that the sprinkler is shooting out 23 ft of water.

This would be the same as the radius of a circle, and we're trying to find the area. Use the formula.

\sf A=\pi r^2

Plug in what we know:

\sf A=\pi (23^2)

\sf A=529\pi ft^2

This is what they could be looking for, an exact value. If they want an approximation, we can input 3.14 for Pi:

\sf A\approx 529(3.14)

\boxed{\sf A\approx 1661.06~ft^2}

Mark is in training for a bicycle race. He needs to ride 50 km a week as part of his training. He rode 18.23 km on Monday and 13
konstantin123 [22]
The answer is B-about 18km


This is because you round 18.23 to 18km


then you round 13.94 to 14km


you add these rounded numbers together


you take it away from 50km


the answer would then me 18km


but it be ABOUT because that was only a rough estimate because it was rounded

What is the area of the sector of the circle below, if the radius is 5 m. and the central angle < AOB measures 88 °. (round a
MariettaO [177]

Answer:

b 19.2

Step-by-step explanation:

a = \pir^{2} for a circle.  We do not want to find the area for a whole circle.  We only want to find the area for part of a circle.  a hole circle is 360 degrees.

a = \frac{88}{360}\pir^{2}

a = \frac{88}{360}\pi(5^{2})

a = 19.2 rounded.
