Answer:

Step-by-step explanation:

The secants form a proportion where the full length of the secant is the denominator of a fraction where the numerator is the external part of the secant.

7/(x + 7) = 6/(15 + 6) Cross Multiply after combining

7 / (x + 7) = 6/(21)

6 * (x + 7) = 7 * 21 Remove the brackets

6x + 42 = 147 Subtract 42

6x = 147 - 42

6x = 105 Divide by 6

x = 17.5

I think I've done this correctly. If you find an error, please let me know and I'll open it for editing.

A packing box has the dimensions 3 by 2 by 5 1/2<br> What is the volume of the box?<br> feet.

Lelechka [254]

Answer:

The volume of packing box is 33 unit³

Step-by-step explanation:

Given as :

The dimension of packing box are 3 by 2 by 5 $\frac{1}{2}$

I.e Length = 3 unit

Width = 2 unit

Height = 5 $\frac{1}{2}$ = 5 + $\frac{1}{2}$ = $\frac{11}{2}$ unit

Let the volume of box = V unit³

∵ The shape of box is similar to the shape of cuboid

So, volume of box = Length × width × Height

Or, V = 3 unit × 2 unit × $\frac{11}{2}$ unit

∴ V = 3 × 11 = 33 unit³

Hence The volume of packing box is 33 unit³ Answer

$\sf{Hey!}$

$\boxed{\underline{Question:}}$

$(\frac{1}{5})^4 = \frac{1}{632}$

If you want the decimal.

$^A^n^s^w^e^r^~:$

$0.0016.$

$\huge\bold{\textbf{\textsf{{\color{EXPLANATION :}{}}}}}$

Apply exponent rule: $(\frac{a}{b})^c =\frac{a^c}{b^c}$

= $\frac{1^4}{5^4}$

$1^4=1$

$=\frac{1}{5^4}$

$5^4=625$

= $\frac{1}{625}$

Hope It Helps. . .
