1 kilogram (kg) is about 2.2 times as heavy as 1 pound (lb). Suppose the function f determines Marcus's weight (in lbs), f ( t )
Karolina [17]

Answer:

1. g(29)=88.18

2. g(t)=\frac{f(t)}{2.2}

Step-by-step explanation:

It is given that 1 kilogram (kg) is about 2.2 times as heavy as 1 pound (lb).

1 kg = 2.2 lb

Let as consider f determines Marcus's weight (in lbs), f ( t ) , given the number of days t since the beginning of 2017.

The function g determines Marcus's weight (in kg), g ( t ) , given the number of days t since the beginning of 2017.

It is given that f ( 29 ) = 194, it means the 29 Marcus's weight (in lbs) is 194.

Using the above conversion we get

1\text{ lb }=\frac{1}{2.2}\text{ kg}

Multiply both sides by 194.

194\times 1\text{ lb }=194\times \frac{1}{2.2}\text{ kg}

194\text{ lb }=88.181818\text{ kg}

It means the 29 Marcus's weight (in kg) is about 88.18.

g(29)=88.18

Since 1 kg = 2.2 lb, it means weight in kg must be multiplied by 2.2 to convert it into lbs.

g(t)\times 2.2=f(t)

Divide both sides by 2.2.

g(t)=\frac{f(t)}{2.2}

Therefore the formula for g using the function f is g(t)=\frac{f(t)}{2.2}.

Martin uses 5/8 of a gallon of paint to cover 4/5 of wall. What is the unit rate at which Martin paints in walls per gallon
MAVERICK [17]

Answer:

24/25 walls per gallon

Step-by-step explanation:

to get per gallon, we want gallon to be zero.

5/8 gallon of paint: 3/5 of wall

multiply by 8/5 on both sides

1 gallon: 24/25 of wall

24/25 walls per gallon.
