the length of the longer leg of a right triangle is 3 ft more than three times the length of the shorter leg. the length of the
Ulleksa [173]

with the pythagorean theorem

\begin{gathered} (4+3x)^2=x^2+(3+3x)^2 \\ 16+24x+9x^2=x^2+9+18x+9x^2 \\ 16+24x+9x^2=10x^2+18x+9 \\ 16+24x+9x^2-9=10x^2+18x+9-9 \\ 9x^2+24x+7=10x^2+18x \\ 9x^2+24x+7-18x=10x^2+18x-18x \\ 9x^2+6x+7=10x^2 \\ 9x^2+6x+7-10x^2=10x^2-10x^2 \\ -x^2+6x+7=0 \end{gathered}

using the formula of the quadratic equation

\begin{gathered} x_{1,\: 2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \\ x1=\frac{-6+\sqrt{6^2-4\left(-1\right)\cdot\:7}}{2\left(-1\right)}=-1 \\ x2=\frac{-6-\sqrt{6^2-4\left(-1\right)\cdot\:7}}{2\left(-1\right)}=7 \end{gathered}

the length cannot be negative, therefore x=7

length of the shorter leg is: 7ft

length of the longer leg is: 3+3(7)= 24ft

length of the hypotenuse is: 4+3(7)= 25ft

Find two mixed numbers or fractions with a quotient of 3.2
sergij07 [2.7K]

Answer:

\frac{32}{10}\\\\\frac{64}{20}\\\\\frac{96}{30}

These all thave the same quotient of 3.2

Step-by-step explanation:

The fractions which are given and and which are also required are called equivalent fraction. In this, the denominator and numerator of both fractions is different, but when you divide the numerator and denominator to get a value, the values of both the fractions are found same.

To find 2 mixed number or fraction with a quotient 3.2.

We can write 3.2 in the fractional form:

3.2 = \frac{32}{10}

Now multiply both the numerator and denominator with 2, we get

\frac{2\cdot32}{2\cdot10}= \frac{64}{20}

which also has the quotient 3.2

Similarly, multiply both numerator and denominator of 32/10 by 3, we get

\frac{3\cdot32}{3\cdot10}=\frac{96}{10}

whici also has the quotient of 3.2

Similarly we can go on to find as many values as we want with the same quotient.
