A client is 45 years old and has a resting heart rate of 75 bpm issa.
Firlakuza [10]

The target heart rate of the 45 year old client with a resting heart rate of 75 bpm is; 135 bpm

Complete question is;

A client is 45 years old and has a resting heart rate of 75 bpm using the karvonen formula what is their target heart rate at an exercise intensity of 60%.

We are given;

Age of client = 45 years

Resting Heart rate = 75 bpm

%Intensity = 60%

The karvonen formula is;

Target Heart Rate = [(max HR − resting HR) × %Intensity] + resting HR

Formula for maximum heart rate is;

Max HR = 220 - age

Max heart rate = 220 - 45

Max HR = 175 bpm

Thus;

Target Heart rate = [(175 - 75) × 0.6] + 75

Target Heart rate = (100 × 0.6) + 75

Target Heart rate = 60 + 75

Target Heart rate = 135 bpm

It would make sense to buy it in pounds because there are 454 grams in a pound and if your serving 500 people with a cupcake that holds 20 grams than that would take 10,000 grams so u would need about 23 pounds of sugar to make 500 cupcake <span />
