$45.58 - e = $19.95 What is e? And to Check is it True or False?

Anettt [7]

We can change up the expression to find e.

45.58 - 19.95 = e.

25.63 is the result of this, so we can check:

45.58 - 25.63 = 19.95.

e = 25.63

Walt received a package that is 2 1/3 inches long, 6 ¾ inches high, and 8 ½ inches wide. What is the surface area of the package

Umnica [9.8K]

The surface area of prism is 185.815 square inches

Solution:

Given that,

$Length = 2\frac{1}{3}\ inches = \frac{3 \times 2 + 1}{3} = \frac{7}{3}\ inches = 2.33\ inches$

$Width = 8\frac{1}{2}\ inches = \frac{17}{2}\ inches = 8.5\ inches$

$Height = 6\frac{3}{4}\ inches = \frac{27}{4}\ inches = 6.75\ inches$

The surface area of package is given as:

$A=2(wl+hl+hw)$

Where,

"l" is the length

"w" is the width

"h" is the height

Substituting the values we get,

$A = 2((8.5 \times 2.33) + (6.75 \times 2.33) + (6.75 \times 8.5))\\\\Simplify\ the\ above\ equation\\\\A = 2(19.805+15.7275+57.375)\\\\A = 2 \times 92.9075\\\\A = 185.815$

Thus the surface area of prism is 185.815 square inches

Solve each system of equation Y=-3x+5 5x-4y=-3

____ [38]

Y = -3x + 5
5x - 4y = -3

   5x - 4(-3x + 5) = -3
5x + 4(3x) - 4(5) = -3
   5x + 12x - 20 = -3
   17x - 20 = -3
   + 20 + 20
      17x = 17
   17    17
      x = 1
      y = -3x + 5
      y = -3(1) + 5
      y = -3 + 5
      y = 2
      (x, y) = (1, 2)

Find volume of cone z=sqrt(x^2+y^2) that is bounded with z=5 and z=7

Nina [5.8K]

Convert to cylindrical coordinates first, using

$\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}$

Then the volume is

$\displaystyle\int_{\zeta=5}^{\zeta=7}\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=\zeta}r\,\mathrm dr\,\mathrm d\theta\,\mathrm d\zeta$
$=\displaystyle\pi\int_{\zeta=5}^{\zeta=7}\zeta^2\,\mathrm d\zeta$
$=\dfrac{218\pi}3$
