Answer:

width: 6

length: 12

Step-by-step explanation:

lenght: 2x

width: x

perimeter: 2l+2w

2(2x)+2(x)=36

4x+2x=36

6x=36

divide each side by 6

Simplify. 3725−−√−2825−−√+6325−−√ 457√ 7√ 257√ 857√

Andru [333]

Answer:

Option A.

Step-by-step explanation:

Consider the given problem is

$3\sqrt{\frac{7}{25}}-\sqrt{\frac{28}{25}}+\sqrt{\frac{63}{25}}$

Using the properties of radical expressions we get

$3\cdot \frac{\sqrt{7}}{\sqrt{25}}-\frac{\sqrt{28}}{\sqrt{25}}+\frac{\sqrt{63}}{\sqrt{25}}$ $[\because \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}]$

$3\cdot \frac{\sqrt{7}}{\sqrt{25}}-\frac{\sqrt{4}\sqrt{7}}{\sqrt{25}}+\frac{\sqrt{9}\sqrt{7}}{\sqrt{25}}$ $[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]$

$3\cdot \frac{\sqrt{7}}{5}-\frac{2\sqrt{7}}{5}+\frac{3\sqrt{7}}{5}$

Taking out common factors.

$\frac{\sqrt{7}}{5}(3-2+3)$

$\frac{\sqrt{7}}{5}(4)$

$\frac{4\sqrt{7}}{5}$

The simplified form of given expression is $\frac{4}{5}\sqrt{7}$

Therefore, the correct option is A.

Central= 127 Radius= 7. What is the length of the indicated arc (x)

tia_tia [17]

Given:

$\begin{gathered} \theta\text{ = 127} \\ r\text{ = 7 mm} \end{gathered}$

Required:

Length of an arc x.

Explanation:

Length of an arc is given as,

$Length\text{ of an arc =}\frac{\theta}{360}\times2\pi\text{r}$

Length of an arc is calculated as,

$\begin{gathered} Length\text{ of an arc = }\frac{127}{360}\times2\times3.14\times7 \\ Length\text{ of an arc = 0.3528 }\times2\times3.14\times7 \\ Length\text{ of an arc = 15.5091 mm} \\ \end{gathered}$

Answer:

Thus the value of the length of an arc is 15.5091 mm

the greatest integer function below, is defined to be the greatest _________ less than or equal to x : f(x)= [[x]] whats the ans

meriva

The greatest integer function is defined as the greatest integer less than or equal to x.
for example,
[x] = greatest integer less than or equal to x.
[3.5] = 3
[-3.6] = -4 (because -4 is less than -3.6)
[-5]=-5
[12]=12
[ π ] = 3
[ π /2 ] = [ 1.57 ] = 1
[ π ] /2 = 3/2 = 1.5
[[ π ] /2 ] = [ 1.5 ] = 1

etc.

It is also called the floor function.
