A-5/a divided by 4/a

maria [59]

Answer:

$\frac{a-5}{4}$

Step-by-step explanation:

the given equation is

$\frac{a-5}{a} /\frac{4}{a}$

from the multiplication rules we know that

$\frac{a}{b}/\frac{c}{d}=\frac{a}{b}*\frac{d}{c}$

so for the given equation changing the sidn of division to multiplication

the equation becomes

$\frac{a-5}{a} * \frac{a}{4}$

a cancels out from both numerator and denominator

so it becomes

$\frac{a-5}{4}$

which is the answer

Elden [556K]

Answer:

available is 111.5cm tall and Olivia is 88.5cm

Step-by-step explanation:

ok so Olivia is half the height of Luca which means the height of Luca divided by 2

177÷2=88.5

so Olivia is 88.5cm tall

we know that Available is 23cm taller than Olivia which means

the height Available= the height of Olivia+ 23cm

=88.5+23

=111.5

so Available is 111.5cm tall

A rectangle is drawn so the width is 5 inches longer than

CaHeK987 [17]

Answer:

$length = l\\width = 5 + l\\Diagonal = 36\\diagonal^2 = (5+l)^2 + l^2\\36^2 = 25 + l^2 +10l + l^2\\1296 = 2l^2 +10l +25 \\2l^2 +10l=1271\\\\l_1=\frac{-10+2\sqrt{2567}}{2\cdot \:2},\:l_2=\frac{-10-2\sqrt{2567}}{2\cdot \:2}$

$l_1=\frac{-5+\sqrt{2567}}{2},\:l_2=\frac{-5-\sqrt{2567}}{2}$

clearly,

$l_{2} \ is \ a \ negative\ number$

So we consider

$l_{1} =\frac{-5+\sqrt{2567}}{2} = 22.83$

Therefore height = 22.8inches
