Answer:

3%

Step-by-step explanation:

If an item cost $450 before tax and the sales tax is $13.50 then the sales tax rate is 3%.

percentage, a relative value indicating hundredth parts of any quantity.

Given that An item cost $450 before tax

The sales tax of the item is $13.50

We have to find the sales tax rate in percentage

To find the percentage we have to multiply x/100 with four hundred fifty which is equal to thirteen point five

x/100×450=13.5

4.5x=13.5

Divide both sides by 4.5

x=13.5/4.5

x=3%

Hence, if an item cost $450 before tax and the sales tax is $13.50 then the sales tax rate is 3%.

Answer:

  1.  f = 9/a +7

  2.  x = (y -5)/3

  3.  x = 3/(y +2)

  4.  l = (P +9)/4

Step-by-step explanation:

I find it convenient to use the fact that a=b/c can be rewritten as c=b/a:

  [tex]a=\dfrac{b}{c}\qquad\text{given}\\\\ac=b\qquad\text{multiply by $c$}\\\\c=\dfrac{b}{a}\qquad\text{divide by $a$, effectively swapping $a$ and $c$}[/tex]

1. f - 7 = 9/a . . . . use the above shortcut

  f = 9/a +7 . . . . add 7

Answer:

29/4   or   7.25

Step-by-step explanation:

Complimentary angles are two angles that add up to 90

Supplementary angles are two angles that add up to 180

Angle ABC = x

Angle CBD = 7y + 4

Angle DBE = 8y + x

If we can find the measure of angle CBD, then we can find x.

We know that CBD + DBE = 180  because they are supplementary. Therefore...

(7y + 4)  +  (8y + x)  =  180

      AND

(7y + 4)  +  (x)  = 90

Now we can use algebra to solve for x and y...

Blah blah blah...

x  =  29/4

y  =  45/4

Answer:

so the answer is 8x+10y

Step-by-step explanation:

since we have to combine like terms like

3y+7y = 10y

and 6x + 2x= 8x

Answer:

Step-by-step explanation:

triangle ABC is an equilateral so all angles and sides are equal to each other

AB = 6

triangle DEF is an isosceles so two of its angles are equal to each other

a triangles angles add up to 180°

to find the measure of these angles we’ll write this equation:

x + x + 40 = 180

and solve for x

2x + 40 = 180

2x = 140

x = 70°

so mF is 70°

Answer:

Step-by-step explanation:

1. The triangles are not similar because the ratios of side lengths are not the same:

  3 : 4 : 5 ≠ 6 : 7 : 8

__

2. We can make the ratios be the same by multiplying the side lengths by a common value, such as 2:

  3 : 4 : 5 = 6 : 8 : 10

If triangle B had side lengths of 6, 8, 10, then it would be similar to triangle A.

Answer:

  x = 3

Step-by-step explanation:

It is convenient to remember the ratios of side lengths of these "special triangles."

The side ratios of ΔABC are 1 : 1 : √2, so BC = AC/√2 = 6.

The side ratios of ΔBCD are 1 : √3 : 2, so BD = BC/2 = 6/2 = 3.

The value of x is 3.

Answer:

D=[0, 8 214.29]

R=[0, 230 000]

Step-by-step explanation:

In order to find the domain, we must think of the least price you can give to the product you are selling. The price cannot be less than zero, since that would mean that you are giving money to the consumer for taking the product away, so zero is the smallest value p can get.

The greatest value the price can get is the one such that the quantity demanded is zero. So we need to determine that price by setting the equation equal to zero and solving for p.

230,000-28p=0

so we get

-28p=-230,000

[tex]p=\frac{-230,000}{-28}[/tex]

so

p=$8,214.29

so the restricted domain for this function would be:

[tex]0\leq p \leq 8,214.29[/tex]

or in interval notation:

D=[0, 8 214.29]

In order to find the range, we just need to determine what's the least and greatest value the function can get. Since this is a linear function, we can find them by just substituting each of the extreme values of the domain in the function, so we get:

q=230,000-28(0)=230,000

q=230,000-28(8214.29)=0

so the range would be:

[tex]0\leq q \leq 230,000[/tex]

or in interval notation:

R=[0, 230 000]

Answer:

log9

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

logx - logy = log([tex]\frac{x}{y}[/tex])

log[tex]x^{n}[/tex] ⇔ nlogx

Given

2(log18- log3) + [tex]\frac{1}{2}[/tex]log[tex]\frac{1}{16}[/tex]

= 2(log([tex]\frac{18}{3}[/tex] ) ) + log[tex](\frac{1}{16}) ^{\frac{1}{2} }[/tex]

= 2log6 + log[tex]\frac{1}{4}[/tex]

= log6² + log[tex]\frac{1}{4}[/tex]

= log36 + log[tex]\frac{1}{4}[/tex]

= log( 36 × [tex]\frac{1}{4}[/tex] )

= log9
