On the way home from rug shopping, Sophia stopped and bought a rectangular cake. The bottom is not frosted, but all other sides

Brums [2.3K]

Answer:

A) Total Surface Area = 164 sq. feet.

B) Radius = 4.5 inches

C) Diameter = 9 inches

Step-by-step explanation:

A)

A rectangular prism has 6 faces. Since bottom is not covered in frosting, we only need to find area of all the 5 faces (surfaces) and sum it.

<em>The length is 8, width is 11, and height is 2 (of the cake).</em>

<em />

Hence, top surface is 8 * 11 = 88

There are 2 sides measuring 8 and 2. So area is 8*2= 16 *2 = 32

THere are other 2 sides measuring 11 and 2. So area is 11 * 2 = 22 * 2 = 44

Total surface area of the cake that has frosting = 88 + 32 + 44 = 164 sq. inches

B)

Top of the cylinder (pineapple cake) is covered in icing. Top is the shape of a circle, which has area $\pi r^2$ , which is given as 63.585

Solving for radius (r), we get:

$\pi r^2=63.585\\r^2=\frac{63.585}{\pi}\\r=\sqrt{\frac{63.585}{\pi}}\\ r=4.5$

radius = 4.5 inches

C)

The diameter is <em>twice the length of the radius</em>.

The diameter is thus D = 2 * r

D = 2 * 4.5 = 9

Diameter = 9 inches

A gerbil cage,priced at $18, is discounted 20% for one week, and then this price is marked up 20%. is the price back to 20% expl

stiks02 [169]

No, it isn't!

first, the discount is 20 percent of 18 dollars, that is 18/5=3.6

this means that during the first week the prize is 18-3.6=14.4

now, the prize is marked up 20 % of 14.4! this is 2.88

so the prize later will be 14.4+2.88, that is 17.28, not 18

what is relevant here is what a number is a percent OF

If aſc and a +b = C, prove that a|b.

mars1129 [50]

Answer with Step-by-step explanation:

Since we have given that

a + b = c

and a|c

i.e. a divides c.

We need to prove that a|b.

⇒ a = mb for some integer m

Since a|c,

So, mathematically, it is expressed as

c= ka

Now, we put the above value in a + b = c.

So, it becomes,

$a+b=c\\\\a+b=ka\\\\b=ka-a\\\\b=a(k-1)\\\\\implies a|b$

a=mb, here, m = k-1

Hence, proved.
