Answer: $\dfrac{11}{20}$ represents the fraction of guests order the signature dish.

Step-by-step explanation:

Since we have given that

Percentage of guest who order the signature dish = 55%

Total percentage = 100

We need to find the fraction of guests order the signature dish.

So, Fraction of guests order the signature dish is given by

$\dfrac{\text{Percentage of guest order the signature dish}}{\text{Total percentage}}\\\\=\dfrac{55}{100}\\\\=\dfrac{11}{20}$

Hence, $\dfrac{11}{20}$ represents the fraction of guests order the signature dish.

Make n the subject of the formula

kogti [31]

Answer:

$\mathsf{ \frac{m + 21}{5} = n }$

Step-by-step explanation:

To make "n" the subject of the formula, rearrange the formula so it begins with " n = "

To isolate the variable "n", you need to inverse the other terms on that side of the equation where "n" really is.

=> m = 5n - 21

there's a "-21" next to "5n", inverse of subtraction is addition, so add 21 on both sides of the equation.

=> m + 21 = 5n - 21 + 21

=> m+ 21 = 5n

There's also a 5 attached to n, that means the multiplication of n with 5, the inverse of multiplication is division, so dividing both sides of the equation by 5

$\mathsf{ \frac{m + 21}{5} = n }$

If a pool is 4 m wide and 16 m diagonally across, how long is the pool? (Pyth. Theorem)

alukav5142 [94]

Answer:

$L=4\sqrt{15}\ m$

$L=15.49\ m$

Step-by-step explanation:

we know that

Applying the Pythagorean Theorem in the rectangular pool

$d^2=L^2+W^2$

where

d is the diagonal of the pool

L is the length of the pool

W is the wide of the pool

we have

$d=16\ m\\W=4\ m$

substitute the given values

$16^2=L^2+4^2$

solve for L

$L^2=16^2-4^2\\L^2=240\\L=\sqrt{240}\ m$

simplify

$L=4\sqrt{15}\ m$

$L=15.49\ m$
