The perimeter of a rectangle is 70 inches. If its length is four times its width, find the dimensions. Write an equation and sol

katen-ka-za [31]

Answer: Length = 28cm

Width = 7cm

Step-by-step explanation:

Let the width be represented by x.

Since the length is four times its width. Therefore, the length would be:

= 4 × x = 4x

The perimeter of a rectangle is calculated as:

= 2(length + breadth)

Therefore, 2(4x + x) = 70

2(5x) = 70

10x = 70

x = 70/10

x = 7

Therefore, width = 7cm

Length = 4x = 4 × 7 = 28cm

If a hospital patient is given 50 milligrams of medicine which leaves the bloodstream at 10% per hour, how many milligrams of me

SpyIntel [72]

Alright
so equation is
$A(t)=Pe^{rt}$
P=initial amount
and t=time
r=rate

given
initial amount is 50
rate is 10%, but decreasing by 10% so -0.1
and time=6

$A(6)=50e^{-0.1*6}$
$A(6)=50e^{-0.6}$
A(6)=27.4406
about 27mg
