If you know how much a penny weighs then you can weigh any amount of pennies and take that weight and divide by the weight of one penny, to get how many there are without counting all the coins.
Answer:
b
Step-by-step explanation:
The equation, in slope-intercept form, of the line that is perpendicular to the line y- 4 = -(x-6) and passes through the point (-2,-2) is y = x.
<h3 />
<h3>How to represent equation in slope intercept form?</h3>
The equation in slope intercept form is represented as follows;
y = mx + b
where
Therefore,
perpendicular lines follows the rule as follows;
m₁m₂ = -1
Therefore,
y - 4 = -(x - 6)
y - 4 = -x + 6
y = -x + 6 + 4
y = -x + 10
Therefore,
-1m₂ = -1
m₂ = 1
Hence, the line passes through (-2, -2).
Therefore,
-2 = 1(-2) + b
b = -2 + 2
b = 0
Therefore, the equation is as follows;
y = x

Answer:
Discounted price = $160
Step-by-step explanation:
Let x be the discounted price of shoes.
Given:
A department store has a discount on shoes based on a percentage of the price.
and marked down on one pair of shoes is $80 to $64.
So, the discounted rate = 80 - 64 = 16
therefore, the percent of discount is.
% value 
% value 
% value 
% value 
% value 
% value = 20%
Find the price for a $200 pair of shoes after the same discount is applied.
So the discount is 20% and the discounted price of the shoe is 80% of $200.
% value 
80 
x = $160
Therefore, the discounted price of the shoe is $160.
It is a product. So it is (B)
Hope I helped :)
