Answer:

$180

Step-by-step explanation:

Since the discount is 40 percent and is also $72, We will cross multiply. 72 x 100 = 40 x what?

7200/40 = 180

The mirror was originally $180.

Solve C = 2πr (solve for "r")<br> C = 15

Jobisdone [24]

C = 2 pi r

but c = 15

15 = 2 pi r
15 = 2 * (22/7) * r
r = (15*7) / 2 / 22
r = 2.386

If the answer can be left in a fraction than this is the solution: 2×5/8=5/4
5/4-1/3=11/12
if you mean the answer must be left in a whole number than.. I don't really know how to do it

These triangles are similar and the sides are proportional. Which proportion correctly describes the situation below?

Veronika [31]

Answer:

Option (3)

Step-by-step explanation:

"If two triangles are similar, their corresponding sides are proportional."

We will check each proportionality ratio given in the options for the given property,

Option (1),

$\frac{QB}{DM}=\frac{DF}{QL}=\frac{LB}{MF}$

$\frac{3.5}{2}=\frac{5}{8.75}=\frac{10.5}{6}$

$\frac{7}{4}=\frac{4}{7}=\frac{7}{4}$

But $\frac{7}{4}\neq \frac{4}{7}$ .

Therefore, this option is not the answer.

Option (2),

$\frac{FM}{LB}=\frac{BQ}{MD}=\frac{QL}{DF}$

$\frac{6}{10.5}=\frac{3.5}{2}=\frac{8.75}{5}$

$\frac{4}{7}=\frac{7}{4}=\frac{7}{4}$

But $\frac{4}{7}\neq \frac{7}{4}$ ,

Therefore, this option is not the option.

Option (3),

$\frac{BQ}{MD}=\frac{QL}{DF}=\frac{BL}{MF}$

$\frac{3.5}{2}=\frac{8.75}{5}=\frac{10.5}{6}$

$\frac{7}{4}=\frac{7}{4}=\frac{7}{4}$

Therefore, this option is the answer.

Option (4),

$\frac{6}{10.5}=\frac{2}{3.5}=\frac{5}{10.5}$

$\frac{4}{7}=\frac{4}{7}=\frac{10}{21}$

But, $\frac{4}{7}\neq \frac{10}{21}$

Therefore, this is not the correct option.
