Answer:

The value of 4 in 400 is 10 times the value of 4 in 40.

Step-by-step explanation:

Given :  40 and 400.

To find : compare the values of the underlined digits .

Solution : We have given  40 and 400.

In 400

4 is place at hundred place

The value of 4 in 400 is 4 hundred.

In 40

4 is place at tens place

The value of 4 in 40 is 4 tens.

ON comparing

The value of 4 in 400 is 10 times the value of 4 in 40.

Therefore, The value of 4 in 400 is 10 times the value of 4 in 40.

Find the length of the leg a of a right triangle with leg length b = 21.5 inches and the hypotenuse c = 31.9 inches. Use a calcu
mylen [45]

The length of the leg a of the right triangle is obtained by applying the Pythagorean theorem which is given as:

\text{opposite}^2+adjacent^2=hypothenus^2

Thus, we have that:

a^2+b^2=c^2

Given that b = 21.5 inches and c = 31.9 inches, we now have:

a^2+(21.5)^2=(31.9^2)a^2+462.25=1017.61a^2=1017.61-462.25a^2=555.36\begin{gathered} a=\sqrt[]{555.36}=23.57 \\ \Rightarrow a=23.6\text{ inches (to one decimal place)} \end{gathered}

Therefore, the length of the leg a of the right triangle is 23.6 inches

Answer:

<h3>\frac{\sqrt{24}- \sqrt{54} }{\sqrt{6}} = -1   </h3><h3>\sqrt{\frac{9}{20}*\frac{10\sqrt{2} }{3\sqrt{5} } = 1.4142</h3><h3>\frac{10\pi\sqrt{2}-8\pi\sqrt{2}}{2\sqrt{2}}  = π =3.14159</h3><h3>\pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}} = π² = 9.8696</h3>

Explanation:

1.) Rewrite √24 = \sqrt{4*6} = 2\sqrt{6}   Rewrite √54 =\sqrt{9*6}= 3\sqrt{6}

Divide both terms by the denominator; √6 cancels. 2-3 = -1

2.) Rewrite as \frac{3}{2\sqrt{5}} ×\frac{10\sqrt{2}}{3\sqrt{5}}  The 3's cancel.  10/2 = 5√2 in the numerator.

√5 × √5 = 5 in the denominator.  The 5's cancel.

That leaves √2 ≈1.4142

3.) Divide the terms in the numerator by the term in the denominator.

√2's cancel.  10π/2 = 5π   8π/2 = 4π  

Subtract and we are left with π = 3.14159

4.) \pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}}  The square roots are reciprocals. They multiply to 1

We are left with π × π = π² ≈  9.8696
