The route to an ancient pyramid is 79 miles long
Elanso [62]

If the speed is 26.33 miles per day. Then the number of miles you traveled on the 4 days will be 105.33 miles.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

The route to an ancient pyramid is 79 miles long.

If you traveled the same amount of time for 3 days.

Then the speed will be

S = 79 / 3

S = 26.33 miles per day

Then the number of miles you traveled on the 4 day will be

26.33 = D / 4

      D = 105.33 miles

More about the speed link is given below.

(-6,2) and (2,-3) distance in simplest form
malfutka [58]

Answer:

answer is √65

Step-by-step explanation:

Distance=

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

distance=

\sqrt{8 ^{2} + ( - 1) ^{2}  }

distance=

\sqrt{64 + 1}

distance=

\sqrt{65}

What is the equation of the line that passes through the point (-2,14) and is perpendicular to the line with the following equat
tino4ka555 [31]

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{2}{5}}x-1\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill

\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{\cfrac{-2}{5}} ~\hfill \stackrel{reciprocal}{\cfrac{5}{-2}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{5}{-2}\implies \cfrac{5}{2}}}

so we're really looking for the equation of a line whose slope is 5/2 and it passes through (-2 , 14)

(\stackrel{x_1}{-2}~,~\stackrel{y_1}{14})\hspace{10em} \stackrel{slope}{m} ~=~ \cfrac{5}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{14}=\stackrel{m}{ \cfrac{5}{2}}(x-\stackrel{x_1}{(-2)}) \implies y -14= \cfrac{5}{2} (x +2) \\\\\\ y-14=\cfrac{5}{2}x+5\implies {\Large \begin{array}{llll} y=\cfrac{5}{2}x+19 \end{array}}

ABC and DBC are complementary angles. 54, what's the measurement of x?
-BARSIC- [3]

I don't really know what your talking about, so i will guess.

 

One angle is 54, and its complememtery is x. So, 90-54=36

x=36

A store discounts a $75 sweater for 25% off. How much did you pay?
Korolek [52]

Answer:

$56.25

Step-by-step explanation:

25% of Original Price = 25% of $75 = 0.25*75 = 18.75

The discount is $18.75. This is amount you save.

Final Price = (Original Price) - (Discount)

Final Price = (75) - (18.75)

Final Price = 56.25
