$\dfrac{1}{6}w\geq2.5\qquad\text{multiply both sides by 6}\\\\\not6^1\cdot\dfrac{1}{\not6_1}w\geq6\cdot2.5\\\\\boxed{w\geq15}$

<u><em>Answer: w≥15 *The answer should be positive sign.*</em></u>

Step-by-step explanation:

multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.

a*c=b*c

multiply by 6 both sides of an equation.

6*1/6w≥2.5*6

simplify by equation.

2.5*6=15

w≥15

Hope this helps!

Thanks!

Have a great day!

Zack and Noah jogged 2/5 of a mile and walked another 1/4 of a mile. How far did they go in all?

Find a common denominator. The lowest one would come from you multiplying 2/5 by 4 on each side and 1/4 by 5 on each side. You are left with 8/20 and 5/20, added together would be 13/20.

Can someone help me with this problem

Maksim231197 [3]

The area of a triangle is .5*b*h = .5x^2

.5x^2 = 27 so

x^2 = 54

x = sqrt(54) = 7.3

Can someone help me with this? <br> **SHOW WORK PLEASE**

FYI, that L in the denominator is factorial.

This is some pretty serious stuff for high school.

My inclination is that the answer is A, which is the definition of <em>e. </em> Let's see if we can show this.

Let's write

$\displaystyle f(n) = \left(1 + \dfrac 1 n \right)^n$

Let's expand this with the binomial expansion

$\displaystyle f(n) =\sum_{k=0}^n {n \choose k} \dfrac{1}{n^k}$

$\displaystyle f(n) =\sum_{k=0}^n \dfrac{n!}{k!(n-k)!} \cdot \dfrac{1}{n^k}$

$\displaystyle f(n) =\sum_{k=0}^n \dfrac{n(n-1)\cdots(n-k+1)}{k! \, n^k}$

Let's focus on when n is really big and on the ks that are relatively small, which make up the bulk of the sum as the terms get small rapidly.

Then that numerator n(n-1)···(n-k+1) ≈ n^k as all the factors are about n.

$\displaystyle f(n)\approx \sum_{k=0}^n \dfrac{n^k}{k!\, n^k}$

$\displaystyle f(n)\approx \sum_{k=0}^n \dfrac{1}{k!}$

OK, we showed for large n this is approximately true, and it will be exactly true in the limit, so we choose

Joe and Sue were trying to calculate the square inches of paper needed to create a cone for the cotton candy. The radius

Feliz [49]

The correct statements are Neither was correct and Joe used the height and radius to calculate the slant height.

<h3>How to find the square inches of paper needed.</h3>

The square inches of paper needed A = surface area of cone + area of overlap

<h3>Surface area of cone</h3>

The surface area of the cone is given by A = πr[r + √(h² + r²)] where

r = radius of cone = 2 in and
h = height of cone = 6 in.

So, A = πr[r + √(h² + r²)]

A = π × 2 × [2 + √(6² + 2²)]

A = π × 2 × [2 + √(36 + 4)]

A = π × 2 × [2 + √40]

A = π × 2 × [2 + 2√10]

A = 2π[2 + 2√10]

A = 4π + 4π√10

<h3>The area of overlap</h3>

The area of overlap A' = wL where

w = width of overlap = 1/2 in and
L = slant height of cone = √(h² + r²)

So, A' = wL

A' = w[√(h² + r²)]

A' = 1/2[√(6² + 2²)]

A' = 1/2[√(36 + 4)]

A' = 1/2[√40]

A' = 1/2 × 2√10

A' = √10

So, the number of square inches of paper needed is A" = A + A'

= 4π + 8π√10 + √10

Since the number of square inches of paper needed is 4π + 4π√10 + √10

So, the correct statements are Neither was correct and Joe used the height and radius to calculate the slant height.
