Answer:
per one foot of aluminum foil it costs .62 cents
Step-by-step explanation:
there are 3 ft in a yard
so 3 x 3 is 9 which is the total amount of feat
then divide 5.58 by 9
5.58 /9 = .62
this means that per one foot of aluminum foil it costs .62 cents
Answer:
A = L x W
Step-by-step explanation:
<em>Because the equation of a rectangle is understood the best way to help you understand the equation of l*w is to break down the definiton of a rectangle.</em>
Defining a rectangle:
The rectangle is a quadrillateral with two parallel sets of sides which are perpendicular to each other.
Understanding it:
Now let's look at a rectangle
Let's say the length is 5 units and the width is 10 units.
To find that meat in between we understand that 5 units of length extends through all 10 units of the width. This means 5 is carried out for 10 units meaning that 5x10 is the area of the Rectangle. As such the area would be 50
So the area of a rectangle is its length times its width
Answer: the fraction 3/7
=====================================================
Explanation:
We have 7 places: India, Tokyo, Houston, Peru, New York, Tijuana, Canada
Out of these 7 places, 3 of them are both a city and in North America. Those three places are: Houston, New York, Tijuana
We divide the two values (smaller over larger) to get the final answer 3/7
writing P(A and B) is shorthand for asking for the probability of getting a city AND that place is also in north america as well.
