Answer:

Distance

=

\sqrt{(a {}^{2} -  a {}^{1}) {}^{2} +(b{}^{2} -  b {}^{1}) {}^{2}   }

=

=  \sqrt{( - 8 + 6) {}^{2}  + (6 - 3) {}^{2} }

\sqrt{4 + 9}

=  \sqrt{13}

=3.61/2

S =The maximum walking speed S, in feet per second, of an animal can be modeled by the equationVgL, where g = 32 ft/sec and L is
grin007 [14]

1.41 times

1) Well, let's get started by writing out the equation:

S=\sqrt[]{gL}

2) Let's find out the maximum walking speed of a giraffe, plugging into that the given data: Giraffe Leg Length: 6

\begin{gathered} S_{\text{giraffe}}=\sqrt[]{32\times6} \\ S_{\text{giraffe}}=\sqrt[]{192}\approx13.86 \end{gathered}

And the hippotamus:

S_{\text{hippo}}=\sqrt[]{32\times3}\Rightarrow\sqrt[]{96}\approx9.80

And now how many times greater by dividing the giraffe's speed by the hippopotamus speed:

\frac{13.86}{9.8}\approx1.41

Hence, the answer is 1.41 times.

I am in fourth grade and I have no idea how to find whole numbers between a fraction can you show me?
allsm [11]

Answer:

To find a a fraction of a whole number, you multiply the numerator of the fraction by the given number and then divide the product by the denominator of the fraction

Solved example for finding a fraction of a whole number:

1)

Find 1/3 of 21.

To find 1/3 of 21, we multiply the numerator 1 by the given whole number 21 and then divide the product 21 by the denominator 3.

1/3 × 21 = 1 × 21/3 = 21/3 = 7

So, 1/3 of 21 = 7.

1/3 of 21 is 7

A student repeatedly measures the mass of an object using a mechanical balance and gets the following values: 560 g, 562 g, 556
MrRissso [65]

Answer: 2.76 g

Step-by-step explanation:

The formula to find the standard deviation:-

\sigma=\sqrt{\dfrac{\sum(x_i-\overline{x})^2}{n}}

The given data values : 560 g, 562 g, 556 g, 558 g, 560 g, 556 g, 559 g, 561 g, 565 g, 563 g.

Then,  \overline{x}=\dfrac{\sum_{i=1}^{10} x_i}{n}\\\\\Rightarrow\ \overline{x}=\dfrac{560+562+556+558+560+556+559+561+565+563}{10}\\\\\Rightarrow\ \overline{x}=\dfrac{5600}{10}=560

Now, \sum_{i=1}^{10}(x_i-\overline{x})^2=0^2+2^2+(-4)^2+(-2)^2+0^2+(-4)^2+(-1)^2+1^2+5^2+3^2\\\\\Rightarrow\ \sum_{i=1}^{10}(x_i-\overline{x})^2=76

Then, \sigma=\sqrt{\dfrac{76}{10}}=\sqrt{7.6}=2.76

Hence, the  standard deviation of his measurements = 2.76 g
