Answer: the depth of the trench is 3685 ft

Step-by-step explanation:

The hole is approximately 347 yards wide. This means that the diameter of the hole is 347 yards.

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder or hole.

h represents the height or depth of the cylinder or hole.

π is a constant whose value is 3.14

From the information given,

Volume = 348289500 ft³

Radius = diameter/2 = 347/2 = 173.5 ft

Therefore,

348289500 = 3.14 × 173.5² × h

348289500 = 94521.065h

h = 348289500/94521.065

h = 3685 feet

The length of a rectangle is four time its width. If the permeter of the rectangle is 100yd, find i t s length and width.​
seropon [69]

Answer:

So let us call the shorter side, i.e the width: 'x'

So each length is four times the width = 4x

The perimeter consists of two widths and two lengths and equals 50 inches.

So:

x+x+4x+4x=50

solve for x:

10x = 50

to find x divide both sides by 10:

10x/10 = 50/10

x=5

So width equals 5 in and length is four times this i.e. 4x5=20

To check: 5+5+20+20=50 !!!!

In a zoo, there are 5 times as many monkeys as there are bears, and the number of bears is 2 fewer than the number of elephants.
HACTEHA [7]

m = 5b

b = e - 2

e = 6


first, solve for the number of bears by replacing e with 6.

b = 6 - 2

b = 4


now do the same for the monkeys.

m = 5b

m = 5(4)

m = 20


check the answer if you wish. the zoo has 20 monkeys.

The points of new triangle is (3,-2), (6,-3) and (2,-5).

<u>Step-by-step explanation:</u>

The given points in the triangle A(-3,7), B(9,3) and C(-7,-5).

The scale factor is \frac{1}{4} and centered at point (5,-5).

The formula to dilate a point that is not centered on a origin is given by,

D(x,y)=(h+t(x-h),k+t(y-t)).

where (h,k) is the center point.

To find A',

D(-3,7)=(5+\frac{1}{4}(-3-5),-5+\frac{1}{4}(7+5)).

D(-3,7)=(5+\frac{1}{4}(-8),-5+\frac{1}{4}(12)).

D(-3,7)=(5-2, -5+3).

D(-3,7)=(3,-2).

To find B',

D(9,3)=(5+\frac{1}{4}(9-5),-5+\frac{1}{4}(3+5)).

D(9,3)=(5+\frac{1}{4}(4),-5+\frac{1}{4}(8)).

D(9,3) = (5+1,-5+2).

D(9.3)=(6,-3).

To find C',

D(-7,-5)=(5+\frac{1}{4}(-7-5),-5+\frac{1}{4}(-5+5)).

D(-7,-5)=(5+\frac{1}{4}(-12),-5+\frac{1}{4}(0)).

D(-7,-5)=(5-3,-5+0).

D(-7,-5)=(2,-5).

∴ The points of new triangle is (3,-2), (6,-3) and (2,-5).
