A scale on a hiking map shows that 33 inches represents 1.25miles. What number of inches on the map represent 1010 actual miles?

user100 [1]

Answer:

26,664 inches

Step-by-step explanation:

Set up a proportion to solve this...

33 inches is to 1.25 miles as 'x' inches is to 1,010 miles

33/1.25 = x/1,010 now solve for x by cross multiplying

33,330 = 1.25x

33,330/1.25 = x

26,664 = x

How would you rewrite x^(9/7) ???

Anastaziya [24]

The given expression is

$x^{9/7}$

We can write it in radical form, and the denominator of the exponent became the power of the radical. That is

$x^{9/7} = \sqrt[7]{x^9}$

And

$\sqrt[7]{x^9} = \sqrt[7]{x^7*x^2}$

We can also write it as

$\sqrt[7]{x^7}*\sqrt[7]{x^2} = x \sqrt[7]{x^2}$

And that's the simplified form of the given exponential form .

A relation is plotted as a linear function on the coordinate plane starting at point E at

Jobisdone [24]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 0}} &,&{{ 27}}~) 
% (c,d)
&&(~{{ 5}} &,&{{ -8}}~)
\end{array}
\\\\\\
% slope = m
\stackrel{\stackrel{average}{rate~of~change}}{slope}= {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{-8-27}{5-0}\implies \cfrac{-35}{5}\implies -7$

well, when x = 0, namely at the very beginning, y = 27, thus, that IS the initial value.
