What is 12% on $3,200 in sales?

Karolina [17]

Answer:

The easiest way of calculating discount is, in this case, to multiply the normal price $3200 by 12 then divide it by one hundred. So, the discount is equal to $384. To calculate the sales price, simply deduct the discount of $384 from the original price $3200 then get $2816 as the sales price.

(8CQ) Find the sum of the geometric series. <br> 20-10+5-5/2+...

Ivahew [28]

Answer:

b. $\frac{40}{3}$

Step-by-step explanation:

The given geometric series is;

$20-10+5-\frac{5}{2}+...$

The first term of this series is

$a_1=20$

The common ratio is

$r=\frac{-10}{20}=-\frac{1}{2}$

The sum to infinity of this series is

$S_{\infty}=\frac{a_1}{1-r}$

Substitute the given values to obtain;

$S_{\infty}=\frac{20}{1--\frac{1}{2}}$

This implies that;

$S_{\infty}=\frac{20}{\frac{3}{2}}$

$S_{\infty}=\frac{40}{3}$

How to find the coordinates of the midpoint of a segment with the given endpoints?

inn [45]

Answer:

see explanation

Step-by-step explanation:

given the endpoints of a line segment

(x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ $\frac{1}{2}$ (x₁ + x₂), $\frac{1}{2}$ (y₁ + y₂) ]

For example

consider the endpoints (4, 2) and (6, - 4)

midpoint = [ $\frac{1}{2}$ (4 + 6), $\frac{1}{2}$ (2 - 4)] = (5, - 1)
