Answer:

$1251.59

Step-by-step explanation:

tax percent = 6.7%

cost price of watch = $113

tax amount = tax percent of total price

=6.7 % * 1173

=6.7/100 *1173

=78.591

Now find total cost of a watch with tax

total cost = tax amount + original cost price

=$78.591 + $1173

=$1251.59

F the sphere shown above has a radius of 5 units, then what is the approximate volume of the sphere?

bogdanovich [222]

<h3>Given:</h3>

Radius= 5 units

The approximate volume of the given sphere.

<h3>Solution:</h3>

$\large\boxed{Formula:V= \frac{4}{3}\pi{r}^{3}}$

Let's substitute the values according to the formula.

Let's solve!

$V=\frac{4}{3}×\pi×{5}^{3}$

$V=523.59878 \: {units}^{3}$

Now, well have to round off to the nearest hundredth.

$\boxed{V=523.6 \: {units}^{3}}$

Hence, the volume of the given sphere is 523.6 cubic units.

Note: If your using π as π you'll get this answer.

A rectangular piece of land borders a wall. The land is to be enclosed and to be into divided 3 equal plots with 200 feet of fen

Answer:

Area = 2500 square feet is the largest area enclosed

Step-by-step explanation:

A rectangular piece of land borders a wall. The land is to be enclosed and to be into divided 3 equal plots with 200 feet of fencing

Let x be the length of each box and y be the width of the box

Perimeter of the box= 3(length ) + 4(width)

$200=3x+4y$

solve for y

$200=3x+4y$

$200-3x=4y$

divide both sides by 4

$y=50-\frac{3x}{4}$

Area of the rectangle = length times width

$Area = 3x \cdot y$

$Area = 3x \cdot (50-\frac{3x}{4})$

$A=150x-\frac{9x^2}{4}$

Now take derivative

$A'=150-\frac{9x}{2}$

Set it =0 and solve for x

$0=150-\frac{9x}{2}$

$150=\frac{9x}{2}$

multiply both sides by 2/9

$x=\frac{100}{3}$

$A''=-\frac{9}{2}$

For any value of x, second derivative is negative

So maximum at x= 100/3

$A=150x-\frac{9x^2}{4}$ , replace the value of x

$A=150(\frac{100}{3})-\frac{9(\frac{100}{3})^2}{4})$

Area = 2500 square feet is the largest area enclosed
