Answer:

29/48

Step-by-step explanation:

3 5/8 Divided By 6= 29/48

Dividing fractions is simple if you know what to do, and how to multiply.

Here's how:

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

1. convert any whole number or mixed number into a fraction.

6 = 6/1.

Whole number x denominator + numerator = 29/8

(3) (8) (5) (answer/original denominator)

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

2. Keep, Change, Flip (KCF)

29 1

__ x __

8 6

With KCF, we keep the first fraction, change the division to multiplication, and flip the second fraction.

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

3. Multiply numerators and denominators

29 x 1 = 29

8 x 6 = 48

29/48 is in it's simplest form.

Hence, your answer.

The perimeter it a square field is 224. How long is

geniusboy [140]

Since each side of a sqare is equal and there are four sides to the square
$224 = 4x$
X being the side length.
Then you would simiply divide by 4 to isolate x
$x = 56$
A side length is 56

A grain silo has the shape of a right circular cylinder surmounted by a hemisphere. If the silo is to have a volume of 505π ft3,

Romashka-Z-Leto [24]

Answer:

radius x = 3 ft

height h = 23,8 ft

Step-by-step explanation:

From problem statement

V(t) = V(cylinder) + V(hemisphere)

let x be radius of base of cylinder (at the same time radius of the hemisphere)

and h the height of the cylinder, then:

V(c) = π*x²*h area of cylinder = area of base + lateral area

A(c) = π*x² + 2*π*x*h

V(h) = (2/3)*π*x³ area of hemisphere A(h) = (2/3)*π*x²

A(t) = π*x² + 2*π*x*h + (2/3)*π*x²

Now A as fuction of x

total volume 505 = π*x²*h + (2/3)*π*x³

h = [505 - (2/3)* π*x³ ] /2* π*x

Now we have the expression for A as function of x

A(x) = 3π*x² + 2π*x*h A(x) = 3π*x² + 505 - (2/3)π*x³

Taking derivatives both sides

A´(x) = 6πx - 2πx² A´(x) = 0 6x - 2x² = 0

x₁ = 0 we dismiss

6 - 2x = 0

x = 3 and h = [505 - (2/3)* π*x³]/2* π*x

h = (505 - 18.84) / 6.28*3

h = 23,8 ft

Solve equation 3(n - 5) = 7 - 2(n + 1)

AlladinOne [14]

Answer:

n= 4

Step-by-step explanation:

3 multiplied by n is 3n.

3 multiplied by -5 is -15.

so 3n-15= 7-2(n+1)

7-2(n+1) is -2 multiplied by n is -2n and -2 multiplied by 1 is -2.

3n-15=7-2n-2

then move the variables to one side and numbers to the one side.

3n+2n=15+7-2

*If you are moving across the equation the symbols change. Like negative to positive. Division to multiplication.

so 5n=22-2

5n=20

5 multiplied by 4 is 20 so n is going to be 4.
