In an isosceles triangle the 2 longest sides are equal
x + 9 = 2x - 8
so x = 17
and the value of BC is x sooooo it's 17

You have 350 feet of fencing to enclose a rectangular plot that borders on a river. If you do not fence the side along the river

IrinaVladis [17]

The length and width that will maximize the area are 175 ft and 87.5 ft respectively

The largest area that can be enclosed is 15312.5 ft²

<h3>Area of a rectangle</h3>

area = lw

where

l = length

w = width

The fencing is 350 ft it is use to enclose a rectangular plot with a river occupying one part.

Therefore,

perimeter = l + 2w

350 = l + 2w

l = 350 - 2w

area = (350 - 2w)w

(350 - 2w)w = 0

where

w = 0 or 175

average = 175/2 = 87.5

Hence, the max area is at w = 87.5 ft

Therefore,

l = 350 - 2(87.5) = 175 ft

length = 175 ft

width = 87.5 ft

Therefore,

area = 175 × 87.5 = 15312.5 ft²

Therefore, the largest area that can be enclosed is 15312.5 ft²

The volume of a certain right circular cylinder is 16. A larger circular cylinder has radius 25% greater and height 50% greater

san4es73 [151]

Answer:

$V_2 = 37.5$

Step-by-step explanation:

Given

$Volume = 16$

Represent the height of the smaller cylinder with h and its radius with r.

The height (H) of the larger cylinder is

$H = h + 50\% * h$

And the radius (R) is;

$R = r + 25\% * r$

Required

Determine the volume of the larger cylinder

Volume of the smaller cylinder is:

$V_1 = \pi r^2h$

Substitute 16 for V1

$16 = \pi r^2h$

While the volume of the larger cylinder is:

$V_2 = \pi R^2H$

We have that:

$H = h + 50\% * h$ and $R = r + 25\% * r$

--------------------------------------------------------------------------------------------------------------

Simplify both expressions

$H = h + 50\% * h$

$H = h + 0.50*h$

$H = h + 0.50h$

$H = 1.50h$

$R = r + 25\% * r$

$R = r + 0.25*r$

$R = r + 0.25r$

$R = 1.25r$

--------------------------------------------------------------------------------------------------------------

Substitute values for R and H in $V_2 = \pi R^2H$

$V_2 = \pi * (1.25r)^2 * 1.50h$

$V_2 = \pi * 1.5625r^2 * 1.50h$

Collect Like Terms

$V_2 = 1.50 * 1.5625* \pi*r^2 * h$

$V_2 = 2.34375* \pi*r^2 * h$

$V_2 = 2.34375* \pi r^2h$

Recall that: $16 = \pi r^2h$

$V_2 = 2.34375* 16$

$V_2 = 37.5$

<em>Hence, the volume of the larger cylinder is 37.5</em>
