Zoe paid $18.60 in sales tax and tips for her dinner. The sales tax rate is 11%and she tipped 20% (The sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax.)
What was the price of Zoe's dinner, before sales tax and tip?

Answers

Answer:

$60 was the price of Zoe's dinner, before sales tax and tip.

Step-by-step explanation:

Sales tax  + tips for dinner = 18.60

The sales tax rate is 11%, and she tipped 20%. Given that the sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax. Let x be the original price

Sales tax = 11% * original price = 0.11 * x= 0.11x

Tips for dinner = 20% * original price = 0.20 * x = 0.2x

We know Sales tax  + tips for dinner = 18.60

0.11x + 0.2x = 18.60

0.31x = 18.60

Divide by 0.31 on both sides

x = 60

Does the equation x+7=12 have the same answer as 2x+14=24? Do you think there is a way to tell without solving each equation? Explain.

Answers

Answer: yes they both have the same answer.

Step-by-step explanation: 12 - 7 equals 4 and 28/7 equals 4

Answer:

yes x is the same in both problems

Step-by-step explanation:

in the first one you subtract seven from both side to leave you with x=5

in the second problem you subtract 14 (2x=10) from both sides then divide both sides by 2 so you are left with x=5

Answers

Answer:

absolute error: 0.4 kgrelative error: 6.1%

Step-by-step explanation:

The absolute error is the difference between the estimate and the actual weight:

  7.0 kg -6.6 kg = 0.4 kg . . . . absolute error

__

The relative error is the ratio of the absolute error to the actual weight:

  (0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error

Step-by-step explanation:

There are 5 red, 3 green, and 4 yellow, so make it into a fraction. In total there are 12 marbles(5+3+4). There are 4 yellow marbles, so the fraction would be 4/12. Turn this into a percent to get the probability. 4/12 = 0.33 = 33%

The graph shows the cost in dollars, y, of a muffin delivery and the number of muffins, x, ordered. The slope of the line is 2 and the y-intercept is 3.

Answers

Answer:

The slope means that every time the x value changes by +1, then the y value will change by +2.

The y-intercept is 3, which means is that when the y value is at 3, the line crosses the y-axis, or x has as value of 0.

For real though, why are there so many questions about slope and intercept, I just finished answering a question like this.

Answers

Answer:

[tex]A^{'}[/tex] = {1,3,5,7,9,....}

[tex]B^{'}[/tex] = {1,2,4,5,7,8,10,11,13,14......}

[tex]D^{'}[/tex] = {10,11,12,13,14,15,......}

Step-by-step explanation:

Solution:

It is given that, Universal set is the set of all Natural Numbers.

and

Set A, Set B, Set  C, Set D are subsets of Universal set.

A = {x:x is even natural numbers} = {2,4,6,8,10,.....}

B = {x:x ∈ N and x is a multiple of 3} = {3,6,9,12,15,....}

C = {x:x∈ N and x < 5} = {6,7,8,9,10,.....}

D = {x:x ∈ N and x > 10} = {1,2,3,4,5,6,7,8,9}
