Regular price = 100% is $100Discounted price = x% is $89
a)
If Janette pays $89 then the percentage paid compared to the original price is = 89/100 = 89%
b)
She received a discount of (100-89) % = 11%Please press the Thank You button and indicate as best answer if these are the answers you're looking for.<span>

Answer:
Step-by-step explanation:
1.51 gram to $ 1567.01 = 2.23 gram to $ x
1.51 / 1567.01 = 2.23 / x
cross multiply because this is a proportion
(1.51)(x) = (1567.01)(2.23)
1.51x = 3494.43
x = 3494.43 / 1.51
x = $ 2314.19 <===== what 2.23 grams of gold is worth
==========================
x = first car and y = new car
x = 28,033.51
y = 2x - 301.26
y = 2(28,033.51) - 301.26
y = 56,067.02 - 301.26
y = $ 55,765.76 <====== new car cost
1 gallons=42.68 miles what about 149.38 miles
149.38 x 1 divided by 42.68
=3.5 gallons

Answer:
7.2
Step-by-step explanation:
The problem statement tells you to use the distance formula to find the distance between points A and B. In order to do that, you need to read their coordinates from the graph. You find A(-5, 5) and B(1, 1).
The distance formula is ...

Using the point coordinates, the formula tells us the distance is ...
d = √((1-(-5))² +(1-5)²) = √(6² +(-4)²)
d = √(36 +16) = √52 ≈ 7.2111
Rounding the distance to the nearest tenth, we have ...
length AB ≈ 7.2 units

<em>About the Pythagorean theorem</em>
If you draw point C(-5, 1) on the graph, then you can see that triangle ABC is a right triangle. It has legs AC and BC. You can subtract coordinates or count grid squares to see that the lengths of those legs are AC = 4, BC = 6.
The Pythagorean theorem tells you the square of the hypotenuse (AB) is the sum of the squares of the sides (AC and BC).
AB² = 4² +6² = 16 +36 = 52
AB = √52 . . . . as above
