Zoe paid 18.60 in sales tax and tips for dinner. The sales tax is 11% and she tipped 20%. 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 = 11% * original price = 0.11 * x= 0.11x
Tips for dinner = 20% * original price = 0.20 * x = 0.2x
0.11x + 0.2x = 18.60
0.31x = 18.60
x = 60
$60 was the price of Zoe's dinner, before sales tax and tip.

Answer:

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

Step-by-step explanation:

1. Sales tax = 11% times original price = 0.11 times x= 0.11x

2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x

3. 0.11x + 0.2x = 18.60

4. 0.31x = 18.60

5. x = 60

6. $60 was the price of Zoe's dinner, before everything else

write as an equation and solve: when 4 is added to the number that is produced by three times the number p, the result is equal to 25.

Answers

Answer:

3p+4=25

Step-by-step explanation:

3p+4=25

Answer:

Equation is 3p+4=25

p=7

Step-by-step explanation:

Isolate the variable

3p + 4 - 4 = 25 - 4

Simplify

3p = 21

Solve for p

3p/3 = 21/3

p=7

State the next term of each sequence
a) 1, 16, 81, 256....
b) 1, 1, 2, 4, 7, 13, 24....

Answers

a) 1, 16, 81, and 256 are all perfect squares. Find their squares:
1, 4, 9, 14.
In this sequence, you first at 3, then 5, then 7. So, logically, you would add 9 next. 14 + 9 is 23, and 23 squared is 529.
b) I'm not sure the data points for this sequence are correct. I'd have to guess 42 based on this difference chart:
1 1 2 4 7 13   24   42
+0 +1 +2 +3 +6 +11 +18
+1 +1 +1 +3 +5   +9
+0 +0 +2 +2   +4
  +0 +2 +0 +2

a)
$1,16,81,256,\underline{625}\n\text{The general formula is } n^4 \text{ where } n\in \mathbb{N}$

b)
$1,1,2,4,7,13,24,\underline{44}\n\text{Each number is the sum of three preceding numbers.}$

What is the volume of a cylinder using pi or 3.14 which the height being 8 and the width being 2

Answers

Answer:

The volume of the cylinder is 25.12

Step-by-step explanation:

The width is the diameter in the circle of the base

radius = half of diameter

r = 2/2 = 1

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 8

π = 3.14

r = radius = 1

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (1)²) * 8

v = (3.14 * 1) * 8

v =3.14 * 8

v = 25.12

The volume of the cylinder is 25.12
