<span>5200mL </span>→ 520 cL → 52dL →<span> 5.2L

</span><span>Example:

If

1L ------ 1000mL
x -------- 5200mL

1000x = 5200
</span> $x = \frac{5200}{1000}$
<span>x = 5,2
</span>
Therefore:
<span>52L > 5200mL or 5.2L (True)

Ava bought some pens for $ 2 each and some pencils for $ 1 each. She bought 3 more pens than pencils and spent a total of $ 12.

Rudiy27

Answer:

Step-by-step explanation:

price of 1 pen= $ 2

price of 1 pencil= $1

total money spent= $12

Let the number of pen be a and number of pencil be b.

2 a + b = 12 ----------------Equation 1

We have, she bought 3 more pens than pencils

a - b = 3 ------------------ Equation 2

Equation 1 +Equation 2,

2 a + b + a - b = 12 + 3

3a = 15

a = 5

Substituting in equation

5 - b = 3

b = 2

Number pencils Ava bought = 2

Given right triangle XYZ, what is the value of tan(60°)?

Svetlanka [38]

we know that

Step $1$

in the right triangle XYZ

Applying the Pythagorean Theorem

Find the value of ZY

$XY^{2}=XZ^{2} +ZY^{2} \\ ZY^{2}=XY^{2}-XZ^{2}\\ ZY^{2}=42^{2}-21^{2}\\ ZY^{2}=1,323\\ ZY=\sqrt{1,323}\ units$

$ZY=21\sqrt{3}\ units$

Step $2$

in the right triangle XYZ

Find tan $60$ °

we know that

$tan\ 60=\frac{opposite\ side\ angle\ 60}{adjacent\ side\ angle\ 60}$

in this problem

opposite side angle $60$ is ZY

adjacent side angle $60$ is XZ

so

$tan\ 60=\frac{ZY}{XZ} \\ \\ tan\ 60=\frac{21\sqrt{3}}{21} \\ \\ tan\ 60=\sqrt{3}$

therefore

the answer is

$\sqrt{3}$

What is the quotient of StartFraction negative 8 x Superscript 6 Baseline Over 4 x Superscript negative 3 Baseline EndFraction?

scZoUnD [109]

Answer:

Option D.

Step-by-step explanation:

We need to find the quotient of

$\dfrac{-8x^6}{4x^{-3}}$

It can rewritten as

$\dfrac{-8}{4}\times \dfrac{x^6}{x^{-3}}$

$-2\times x^{6-(-3)}$ $[\because \dfrac{a^m}{a^n}=a^{m-n}]$

$-2x^{6+3}$

$-2x^{9}$

The required expression is $-2x^{9}$ .

Therefore, the correct option is D.
