Alina [70]

Answer: It means the value is rational

Step-by-step explanation:

Repeating decimals can be converted to fractions and rational numbers are numbers that can be expressed as a fraction but irrational numbers cannot be expressed as a fraction and neither does it terminate or repeat.

Solve V=1/3bh for h. (1/3 is a fraction, idk if that matters.)

Vadim26 [7]

Answer:

3V/b = h

Step-by-step explanation:

Step 1: Write equation

V = 1/3bh

Step 2: Multiply both sides by 3

3V = bh

Step 3: Divide both sides by b

3V/b = h

Match each description to its example.

kvv77 [185]

Answer:

if we have the point (x, y), a reflection over the x-axis give us the point (x, -y)

if we have the point (x, y), a reflection over the y-axis give us the point (-x, y)

if we have the point (x, y), a reflection across both axes give us the point (-x, -y)

1. (2, -3) → (-2, -3) ------- reflection across the y-axis

2. (2, -3) → (-3, 2) -------- not a reflection

3. (2, -3) → (-2, 3) ------ reflection across both axes

4. (2, -3) → (2, 3) ----- reflection across the x-axis

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.
