The answer is b. a triangle is equal to 180. to find x the equation would be 180= 3x-100+x-10+x-10 which is equal to 60. then sub 60 in to each equation. 3(60)-100=80, 60-10=50, 60-10=50

A pack of cinnamon-scented pencils sells for $8.00. What is the sales tax rate if the total cost of the pencils is $8.64?
vesna_86 [32]
Selling price of a pack of cinnamon scented pencils = $8
Cost of the pack of pencils along with tax = $8.64
Then
Amount of tax taken = (8.64 - 8.00) dollars
                                 = 0.64 dollars
Percentage of sales tax taken = (0.64/8.00) * 100
                                                 = 64/8
                                                 = 8 percent
So the rate of sales tax for the pack of cinnamon scented pencils is 8%. I hope the procedure is clear enough for you to understand. You can use this method for solving similar problems without requiring any help from outside.

Ashley’s Phone bill went from 32.25 to 18.70 what was the percent of decrease? Plz help a little confused...plz explain how you
Kruka [31]

Answer:

42%

Step-by-step explanation:

To find the percent of decrease first find the difference between 32.25 and 18.70.

32.25 - 18.70 = 13.55

Now divide this number by the original number, in this case 32.25, and then multiply the answer you get by 100.

13.55 / 32.25 = 0.42

Multiply this number by 100 to get the percentage.

0.42 * 100 = 42

What is the answer to this geometry problem
Marizza181 [45]
Because we were not given any specific point to start off with. I choose (2,2), which is shown in red as 1.

We translate it 2 times.
a) (x+5)(y+3) = (2+5)(2+3) = (7,5) is our new point (shown in brown as 2)
     Translation process shown in yellow.

b) (x-4)(y+2) = (7-4)(5+2) = (3,7) is our final point (shown in orange as 3)
    Note that we use the 2nd point for the second translation as required.
    Translation process shown in lime.

We can therefore determine from the picture below that you can use the translation (x+1)(y+5), which the translation process is shown in blue.
Proof: (x+1)(y+5) = (2+1)(2+5) = (3,7)

Now let's do it again, except we do the second translation first and the first translation last.

c) (x-4)(y+2) = (2-4)(2+2) = (-2,4) is our new point (shown in purple as 4)
    Translation process shown in pink.

d) (x+5)(y+3) = (-2+5)(4+3) = (3,7) is our final point (shown in orange as 3)
    Translation process shown in dark blue.
    Same rules as (b). Notice how the final point is still the same? Therefore it     makes no difference.

Hope I helped a lot :P

(2×100)+(9×10)+(6×1)+(3×1/10)+(8×1/100)= <br> In standard form
Sidana [21]
We know that standard form = the number that is not expanded.
This equation is expanded so standard form =

2*100=200
9*10=90
6*1=6
3*1/10= 0.3
8*1/100=0.08

200+90=290
290+6=296
296+0.3=296.3
296.3+0.08=296.38

Your answer is 296.38
Hope this helped!
