** Calculation is based on 52 weeks per year.

$\smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile$

$\boxed {Annual \ Premium \ = \$2530}$

Your employer is paying 75% of the Premium:
$\boxed {75\% \ of \ \$2530 \ = \ 0.75 \times 2530\ = \ \$1897.50}$

Amount you need to pay:
$\boxed { \$2530 - \$1897.50 = \$632.50}$

Amount needed to be deducted weekly from paycheck:
$\boxed{ \$632.50 \div \ 52 = \$12.16}$

$\Bigg( \boxed{ \boxed {Ans: \$12.16 }} \Bigg)$

Write the equation of the circle in standard form: Center (7,0) R=1

Mice21 [21]

Answer:

$(x-7)^2+y^2=1$

Step-by-step explanation:

Hi there!

Equation of a circle: $(x-h)^2+(y-k)^2=r^2$ where the circle is centered at (h,k) and the radius is r

<u>1) Plug in the given center (7,0)</u>

$(x-7)^2+(y-0)^2=r^2\\(x-7)^2+y^2=r^2$

<u>2) Plug in the radius (1)</u>

$(x-7)^2+y^2=1^2\\(x-7)^2+y^2=1$

I hope this helps!

A solid is formed by adjoining two hemispheres to the ends of a right circular cylinder. An industrial tank of this shape must h

mestny [16]

Answer:

Radius =6.518 feet

Height = 26.074 feet

Step-by-step explanation:

The Volume of the Solid formed = Volume of the two Hemisphere + Volume of the Cylinder

Volume of a Hemisphere $=\frac{2}{3}\pi r^3$

Volume of a Cylinder $=\pi r^2 h$

Therefore:

The Volume of the Solid formed

$=2(\frac{2}{3}\pi r^3)+\pi r^2 h\\\frac{4}{3}\pi r^3+\pi r^2 h=4640\\\pi r^2(\frac{4r}{3}+ h)=4640\\\frac{4r}{3}+ h =\frac{4640}{\pi r^2} \\h=\frac{4640}{\pi r^2}-\frac{4r}{3}$

Area of the Hemisphere = $2\pi r^2$

Curved Surface Area of the Cylinder = $2\pi rh$

Total Surface Area=

$2\pi r^2+2\pi r^2+2\pi rh\\=4\pi r^2+2\pi rh$

Cost of the Hemispherical Ends = 2 X Cost of the surface area of the sides.

Therefore total Cost, C

$=2(4\pi r^2)+2\pi rh\\C=8\pi r^2+2\pi rh$

Recall: $h=\frac{4640}{\pi r^2}-\frac{4r}{3}$

Therefore:

$C=8\pi r^2+2\pi r(\frac{4640}{\pi r^2}-\frac{4r}{3})\\C=8\pi r^2+\frac{9280}{r}-\frac{8\pi r^2}{3}\\C=\frac{9280}{r}+\frac{24\pi r^2-8\pi r^2}{3}\\C=\frac{9280}{r}+\frac{16\pi r^2}{3}\\C=\frac{27840+16\pi r^3}{3r}$
