Set up an equation to represent the areas of the shapes in the table:
(area of rectangle) - 2(area of circle)
There is a 2 in front of the area of the circle, since there are two identical circles punched out of the rectangle.
First, find the area of the rectangle. The area of the rectangle is given by the following formula:
length * width
You already have your two values for length and width. Plug those values into the formula:
236 is the area of the rectangle.
Now we'll find the area of the circle.
The diameter of the circle is 2. The radius is one half of the diameter, so the radius is 1.
The area of a circle is found with the following formula:
pi is equal to 3.14, so replace the pi symbol with the 3.14. Then, plug your radius into the equation.
The area of the circles is 3.14.
Plug your areas into the first equation above.
The approximate area of the cardboard is
229.72.
Numbers can be expressed, ordered and compared by a lot of mathematical principles, properties, models and paradigms. There are different properties of numbers to associate, group and distribute numbers. For example commutative property of addition, 1 + 2 = 3 can be 3 = 1 + 2. Moreover, numbers can be expressed by mathematical form, thus 100 wherein 1 is in the place order of hundreds. And so on… other examples can be mathematical symbols or inequality to compare numbers. For example, 1 > 2. One is less than 2.
Answer:
y = 10852 bacteria
Step-by-step explanation:
The equation is exponential growth
y = a b^x where a is the initial amount , b is the growth rate and x is the time
At time 0, we have 5000 bacteria
5000 = a * b^0
5000 = a *1
a = 1
At 4 hours, we have 6000 bacteria
6000 = 5000 * b^4
Divide each side by 5000
6000/5000 = b^4
6/5 = b^4
Take the 4th root of each side
(6/5)^(1/4) = (b^4)^(1/4)
1.046635139 = b
Our equation is
y = 5000 (1.046635139) ^ x
We want to find the number of bacteria present after 17 hours
y = 5000 (1.046635139)^17
y=10851.51313
To the nearest whole number
y = 10852 bacteria
