Answer:

$\large\boxed{\dfrac{1}{5(m-4)}}$

Step-by-step explanation:

One (1) over (fraction) five m (5m) - 20:

$\dfrac{1}{5m-20}$ <em>distributive</em>

$\dfrac{1}{(5)(m)-(5)(4)}=\dfrac{1}{5(m-4)}$

Find the missing value when given the modulus. <br><br> |48+bi|=50

xxMikexx [17]

Answer:

missing value b is 14

Step-by-step explanation:

We have been given the modulus of a complex number which is

$r=\sqrt{a^2+b^2}$

Here on comparing the given complex number with general a+bi we get:

a=48 and b=b

On substituting the values in the formula for modulus we get:

$\sqrt{48^2+b^2}=50$

$\Rightarrow 2304+b^2=50^2$

$\Rightarrow b^2=2500-2304$

$\Rightarrow b^2=196$

$\Rightarrow b=\sqrt{196}$

$\Rightarrow b=14$

Therefore, missing value b is 14

Iris is building a model of the Washington Monument. Her model measures 15 in. tall and is 1.5 in. wide at the base. The actual

irina [24]

Using how tall it is over how wide
=>tall/wide
The model 15in/1.5in
The actual x/55ft

Convert everything into the same units so 55ft to inches
There are 12in in 1ft
55ft * 12in/1ft
The ft cross out leaving in
55*12in= 660 in

So
15in/1.5in = x/660in
Now solve for x my multiplying both side by 660in
660in *15in/1.5in=x
x= 6600in tall
