the price of an item originally priced at $24 was increased by 15%. what percentage decrease will restore it to its original pri

konstantin123 [22]

Answer:

$20.40

Step-by-step explanation:

First of all we find the value of 10%, so we do 24 ÷ 10 which equals to 2.4, then we find the halved value of 2.4, so we do 2.4 ÷ 2 which equals to 1.2. Then we add 2.4 and 1.2 together, which then gives us 3.6 as the number. We then subtract 3.6 from 24 which gives us 20.4, but we need in money terms so we change it to $20.40. Hope this helps.

Given f(x)=4x^3+7x^2-7x-10 factor f(x), given that -1 is a zero

stira [4]

If - 1 is a zero then
$(x + 1)$
is a factor.

Dividing with this factor using the long division approach, we get the quadratic factor to be,

$4 {x}^{2} + 3x - 10$
(see attachment).

We can rewrite the polynomial as
$f(x) = (x + 1)(4 {x}^{2} + 3x - 10)$

We can further factor as

$f(x) = (x + 1)(4 {x}^{2} - 5x + 8x - 10)$
That is

$f(x) = (x + 1)(x + 2)(4x - 5)$

in germany, VAT is at 19% Jeremy buys a calculator in germny for €58.31 This price includes VAT Find the amount of VAT paid by

Len [333]

We can use this equation to solve this problem:

t=p+(p⋅r)

Where:

t is the total price paid: 58.31 for this problem

p is the price before taxes: What we are solving for in this problem.

r is the tax or VAT rate: 19% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 19% can be written as 19100 or 0.19.

Substituting and solving for p gives:

58.31=p+(p⋅0.19)

58.31=1p+0.19p

58.31=(1+0.19)p

58.31=1.19p

58.311.19=1.19p1.19

49=1.19p1.19

49=p

p=49

Now, we can find how much the VAT was by taking 19% of 49:

19%×49=0.19×49=9.31

Another was to solve this is to subtract the price without the tax or VAT from the total price giving:

58.31−49=9.31

Jarron has a piece of chalk tied to the end of a

solniwko [45]

Answer: A 24 cm piece of string is cut into two pieces , one piece is used to form a circle and the other piece is used to form a square.

How should this string be cut so that the sum of the areas is a minimum .

:

Let x = the circumference of the circle

then

(24-x) = the perimeter of the square

:

Find the area of the circle

find r

2*pi*r = x

r =

Find the area of the circle

A =

A = sq/cm, the area of the circle

:

Find the area of the square

A = sq/cm the area of the square

The total area

At = +

Graph this equation, find the min

Min occurs when x=10.6 cm

cut string 10.6 cm from one end

Step-by-step explanation: Hope I help out alot (-: :-)
