How do you figure out tax percentages?

1 answer:

4 0

Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
Make sure you put the sales tax into decimal form. You do this by taking the percentage and sliding the decimal point two places to the left:
7.5% sales tax becomes .075 in decimal form
3.4% sales tax becomes .034 in decimal form
5% sales tax becomes .05 in decimal form
Example: $60 (item cost) x .075 (sales tax) = $4.5 total sales tax

A chicken casserole recipe serves 12

Musya8 [376]

Answer:

4.5 cups of spinach

Step-by-step explanation:

we know that

The recipe serves 12 people and calls for 3 cups of spinach

using proportion

Find out how many cups of spinach should you use, to serve 18 people

$\frac{12}{3}\ \frac{people}{cups} =\frac{18}{x}\ \frac{people}{cups}\\\\x=18(3)/12\\\\x=4.5\ cups$

1. Explain what the slope represents in this situation. please help

DanielleElmas [232]

Answer:

The slope is how much he saves per week (In this case it would be $5 per week)

Step-by-step explanation:

Slope is rise/run or change in y/change in x

In this graph, from x=0 to x=8, the rise or change in y is 40$ and the run or change in x is 8 weeks. So the slope is $40/8 weeks, or $5/week

Please help with these two questions

nevsk [136]

Answer:

10. Let m<Y = y.

Then,

m<Y + m<X +m<Z = 180 [ Sum of angles of triangle is 180 degrees]

or, y + (6x-23) + (4x + 9) = 180

or, y + 10x -14 = 180

or, y = 194 - 10x

or, m<Y = 194 - 10x

12. Solution,

a. m<1 = 60 degrees [Each angles of equilateral triangle is equal to 60 degrees]

b. In triangle WYZ,

m<Z + m<ZWY + m<ZYW =180 [Sum of angles of triangle is 180]

or, 138 + m<ZWY +m<ZWY =180 [Base angles of isosceles triangle are equal, i.e. m<ZYW = m <ZWY]

or, 2 (m<ZWY) = 180 -138 = 42

or, m<ZWY = 21 = m<ZYW

or, m<3 = 21 = m<5

c. Solution,

m<XWY = m<2 + m<3 [Addition axiom]

or, 60 = m<2 + 21 [Each angle of equilateral triangle is 60]

or, m<2 = 39

d. Solution,

m<4 + m<5 =60 [<XYW = 60 ]

or, m<4 + 21 = 60

or, m<4 = 39

How do I solve this limits problem?

motikmotik

Each piece of this function is continuous on its respective domain (because all polynomials are continuous functions), meaning

• 2 - x exists for all x < -1

• x exists for all -1 ≤ x < 1

• (x - 1)² exists for all x ≥ 1

So this really just leaves the points where the pieces are split up, i.e. x = -1 and x = 1. At both of these points, the two-sided limit exists as long as the one-side limits from both sides exist and are equal to one another.

At x = -1, as I said in my comment, you have

$\displaystyle \lim_{x\to-1^-}f(x) = \lim_{x\to-1}(2-x) = 2-(-1) = 3$
