Surface area of sphere =60.82m^2
4pi×r^2=60.82
4×22×r^2/7=60.82
r^2=60.82×7/22×4
r^2=425.74/88
r^2=4.83
r=2.19
or r=2.2m

A trimaran boat, with a top speed of 55 knots, won the tournament cup in 2010. Its top speed is 6 knots more than 3.5 times the
slavikrds [6]

Answer:

14 knots

Step-by-step explanation:

We know the speed (55 knots) is 6 more than 3.5 times the winner of the monohull in the 2007 tournament.

So let's set the variable for the speed of the monohull to <em>m</em>. Now, let's set up an equation:

55 = 6 + (3.5 * m)

We can solve this by first subtracting 6 from both sides to get:

49 = 3.5 * m

Dividing both sides by 3.5 we get:

14 = m

That means that the top speed of the monohull in the 2007 tournament was 14 knots

Suppose the man in the St. Ives poem has x wives, each wife has x sacks, each sack has x cats, and each cat has x kits. Write an
marishachu [46]

Answer: x+x^2+x^3+x^4

Step-by-step explanation:

As per given,

Number of wives = x

Number of sacks = x (\text{Number of wives} )= x\times x = x^2

Number of cats = x(\text{Number of sack})= x \times x^2=x^3

Number of kits = x(\text{Number of cats} )=x\times x^3=x^4

Now , the total number of kits, cats, sacks, and wives going to St. Ives = x+x^2+x^3+x^4

Hence, the required ex[pression:  x+x^2+x^3+x^4

Elena L [17]
112oz(lb/16oz)+x≤22

7+x≤22

x≤15

So she can pack 15 more pounds without going over the limit.

Which of the following is the solution to the differentiable equation dy/dx=4x/y, where Y(2)=-2
aliya0001 [1]

First we'll substitute \frac{dy}{dx} with y'

y'=\frac{4x}{y}

Then we can separate this.

yy'=4x

Then we'll solve this.

yy'=4x: \frac{y^2}{2}=2x^2+c_1

\frac{y^2}{2}=2x^2-6

y=2\sqrt{x^2-3},y=-2\sqrt{x^2-3}

Then we'll plug in to find the extraneous solutions (if any)

y=-2\sqrt{x^2-3}

1. Find the Surface Area of the rectangular prism. Show your work and explain how you solved using First,
mafiozo [28]

Answer:

376 inches^2

Step-by-step explanation:

<h3>1. Divide up each type of rectangle </h3>

- 10x6

- 6x8

- 8x10

<h3>2. Find the area of each rectangle</h3>

- 10x6=60

- 6x8=48

- 8x10=80

<h3>3. Multiply each rectangle by two to get the opposite one</h3>

- 60x2=120

- 48x2=96

- 80x2=160

<h3>4. Add them together</h3>

120+96+160=376

The surface area is 376 inches^2
