Answer:

The amount of tax paid is C. $3.20

Step-by-step explanation:

If we take $50.00 and give a 20% discount, we're taking 20% of 50 and then subtracting it from the origional price (50) which brings us down to 40, because 20% of 50 is 10 and we subtract.

Now that we have $40.00, sales tax comes in at a whopping 8%. To calculate the solution of a price with sales tax, we need to find what 8% of $40 is, which after calculations will be 3.20.

Since this question is asking on tax only, our answer is $3.200, C.

Use distributive law to factor the given expression: 3+21a+15b
Reil [10]

Answer:

3(1+7a+5b)

Step-by-step explanation:

The distributive law states that

a\cdot (b+c)=a\cdot b+a\cdot c.

The expression 3+21a+15b consists of three terms:

  1. 3=3·1;
  2. 21a=3·7a;
  3. 15b=3·5b.

You can see that 3 is the common factor of these three terms, thus

3+21a+15b=3(1+7a+5b).

Mr. Toney gets his car washed every 15 days. Mr. Brown gets his car washed every 20 days. Today, they are both getting their car
Zinaida [17]
They both get their cars washed on every 60th day.


You can solve this equation by finding the lcm (least common multiple):

15 30 45 60 75 90 105

20 40 60 80 100

The lowest common multiple is 60 as it is the first multiple the two have in common.

So, in sixty days, they’ll both get their car washed again

A sphere has a volume of Vequals=3600 in cubedin3. Find its surface area.
Mice21 [21]
\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\qquad 
\begin{cases}
r=radius\\
------\\
V=3600
\end{cases}\implies 3600=\cfrac{4}{3}\pi r^3
\\\\\\
3600=\cfrac{4\pi r^3}{3}\implies \sqrt[3]{\cfrac{3\cdot 3600}{4\pi }}=\boxed{r}\\\\
-----------------------------\\\\
\textit{surface area of a sphere}\\\\
S=4\pi r^2\implies S=4\pi \left(\boxed{\sqrt[3]{\cfrac{3\cdot 3600}{4\pi }}}  \right)^2
