The width of a rectangle measures (2p-5) centimeters, and its length measures (8p+8)centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

The expression that represents the perimeter, in centimeters, of the rectangle=20p + 11 centimeters

Step-by-step explanation:

Perimeter of a rectangle = 2(l+w)

length measures (8p+8)centimetres.

width  measures (2p-5) centimeters,

Such that Perimeter= 2 L +2 W

Perimeter= 2( 8p+8) + 2(2p-5 )      This gives the expression to solve for the Perimeter

Solving

Perimeter= 2( 8p+8) + 2(2p-5 )

Permeter= 16p+ 16+ 4p-5

 Perimeter=   16p+4p+16-5

Perimeter= 20p + 11 centimeters

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
