Kanya is comparing the rate for shipping and handling for two online shopping websites. For the item she has selected, Big Barga

kari74 [83]

Answer:

D. Discount Deals Depot; $15.20

Why?
Lets do Big Bargain Bonanza first.
$8.00 would stay the same as it is for handling. The only number that would change is $1.25, it uses the the words PER pound for shipping.

Your equation would look like this with p being how many pounds Kanya is shipping:
$8.00+$1.25p

Now we just plug in the numbers.
$8.00+$1.25(6)=
$8.00+$7.50=
$15.50

The same games for Discount Deals Depot.
$9.50+$0.95(6)=
$9.50+$5.70=
$15.20

So in conclusion Discount Deals Depot; $15.20 is cheaper than Big Bargain Bonanza;$15.50

A can of beans has surface area 337 cm2. It's heights is 11cm. What is the radius of the circular top?

Karolina [17]

Answer:

3.66 cm

Step-by-step explanation:

r = Radius of cylinder

h = Height of the cylinder = 11 cm

A = Total surface area of the cylinder = $337\ \text{cm}^2$

Total surface area of a cylinder is given by

$A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r(r+h)\\\Rightarrow \dfrac{A}{2\pi}=r^2+rh\\\Rightarrow r^2+rh-\dfrac{A}{2\pi}=0\\\Rightarrow r^2+11r-\dfrac{337}{2\pi}=0\\\Rightarrow r^2+11r-53.64=0\\\Rightarrow 100r^2+1100r-5364=0\\\Rightarrow r=\dfrac{-1100\pm \sqrt{1100^2-4\times 100\left(-5364\right)}}{2\times 100}\\\Rightarrow r=3.66,-14.65$
