Word Problem The Waist to Hip Ratio (WHR) is a ratio commonly expressed as a decimal that has been shown to be a good predictor

of possible cardiovascular problems in both men and women. If Kevin has a WHR greater than 1, he is considered to be “high risk” for cardiovascular problems. Calculate Kevin’s WHR with a waist measurement of 42 inches and a hip measurement 2 inches less.

Answer:

1.05

Step-by-step explanation:

The Waist to Hip Ratio (WHR) is calculated by comparing the waist measurement to the hip measurement.

Here, the waist measures 42 inches, and the hip measurement is 2 inches less, resulting in a hip measurement of 40 inches.

This leads to a WHR of 42 divided by 40, giving 1.05.

The ratio of the waist to hip measurements is $\boxed{\bf 1.05}$ and indicates he is at high risk for cardiovascular issues.

Further explanation:

The ratio refers to a quantitative relationship between two amounts.

<pthis can="" be="" expressed="" as="" src="https://tex.z-dn.net/?f=a%3Ab" id="TexFormula2" title="a:b" alt="a:b" align="absmiddle" class="latex-formula">, where $a$ and $b$ denote the real numbers.<pthe ratio="" src="https://tex.z-dn.net/?f=a%3Ab" id="TexFormula5" title="a:b" alt="a:b" align="absmiddle" class="latex-formula"> is represented as a fraction, written as $\frac{a}{b}$ where $a$ is divided by $b$ .

Given:

Kevin has a waist measurement of $42\text{ inches}$ and his hip measurement is $2\text{ inches}$ inches less than his waist measurement.

Calculation:

Step 1:

We first determine Kevin’s hip measurement.

His hip measurement is $2\text{ inches}$ inches less than the waist, which is $42\text{ inches}$ .

Thus, subtract $2\text{ inches}$ from $42\text{ inches}$ to find the hip measurement.

This can be expressed mathematically as:

$\begin{aligned}\text{Hip measurement}&=42-2\\&=40\end{aligned}$

Step 2:

Next, we calculate Kevin’s WHR.

This ratio, referred to as “WHR”, can be defined mathematically:

$\boxed{\text{WHR}=\dfrac{\text{Waist measurement}}{\text{Hip measurement}}}$ …… (1)

Substituting the values for waist and hip measurements into equation (1):

$\begin{aligned}\text{WHR}&=\dfrac{42}{40}\\&=\dfrac{21}{20}\\&=1.05\end{aligned}$

The resulting value for WHR is $1.05$ .

The waist to hip ratio (WHR) acts as a predictor of cardiovascular issues for both genders.

The ratio should remain below $1$ as exceeding this threshold indicates a high risk for cardiovascular problems.

<ptherefore kevin="" waist="" to="" hip="" ratio="">(WHR) is higher than $1$ .<pthus he="" is="" identified="" as="" being="" at="" high="" risk="" for="" cardiovascular="" issues.="">

Consequently, the waist to hip ratio is $\boxed{\bf 1.05}$ , indicating he is in the high risk of cardiovascular problems.
