The maxwell family goes out for dinner and the price of the meal is $60 the sales tax on the meal is 7% and they also want to le

sukhopar [10]

So we start with the $60 untouched.

Then we add the tax which is $60•0.07= 4.20 that is the tax

Then add the tax to the total $60 + $4.20= $64.20

Next we must add the tip so $60•0.15= 9.

Then $64.20 + $9.00 = $73.20

Total cost of meal $73.20

Any questions? :)

If M is the midpoint of XY, find the coordinates of X if M(-3,-1) and Y(-8,6)

vova2212 [387]

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
X&({{ a}}\quad ,&{{ b}})\quad 
% (c,d)
Y&({{ -8}}\quad ,&{{ 6}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)$

$\bf \left( \cfrac{-8+a}{2}~,~\cfrac{6+b}{2} \right)=\stackrel{M}{(-3,-1)}\implies 
\begin{cases}
\cfrac{-8+a}{2}=-3\\\\
-8+a=-6\\
\boxed{a=2}\\
----------\\
\cfrac{6+b}{2}=-1\\\\
6+b=-2\\
\boxed{b=-8}
\end{cases}$

Rounded to three decimal places, the value of the irrational number e is .A.3.142B.3.615C.2.718D.2.947

notka56 [123]

REQUIRED:

Round to 3 decimal placed the value of the irrational number e.

Step-by-step solution/explanation;

The letter e in mathematics is also known as the Eular's number and is a mathematical constant used in many calculations especially natural logarithms of numbers.

The value of the Eular's number is approximately;

$e\approx2.71828182846...$

It can continue till infinity, however approximations of this number is always used to avoid unnecessary complications.

Therefore, rounded to 3 decimal places, the value of e is now;

ANSWER:

$e\approx2.718$

Note that we take 3 digits aftre the decimal and then if the fourth digit after the decimal is 5 or greater than 5, we make it 1 and add that 1 to the third digit after the decimal. Otherwise we simply make it zero and cancel it along with all other digits after it.

The digit that follows 8 (third digit) is less than 5, therefore, we write it off along with all other digits after it, and we are left with the decimal point and then ...718.

Option C is the correct answer.
