Answer:
Step-by-step explanation:
Since the country wants to reduce the emission by the percentage each year, the function will be decaying function. The formula of decaying function will look like this
Where
E(t) = the number of emission after t years
E0= the number of initial emission= 40 million tons
r=rate of growth/decay = 35%= 0.35
t= time in years
If we put the number, the equation will be:
Answer:
McDonald’s hamburger has a greater volume, compared to Wendy’s hamburger.
McDonald’s hamburger is 0.5 cubic Inch bigger.
Step-by-step explanation:
Volume of square burger = 4 * 4 * 3/16 = 3 cubic Inch
Area of the circular hamburger:
pi * diameter
Volume of the circular hamburger =
pi * diameter * thickness
pi * 4.5 * 1/4 = 3.53429173528852 cubic Inch
rounded answer is 3.5 cubic
McDonald’s circular hamburger has a greater volume, compared to Wendy’s hamburger, a bit more then 0.5 cubic Inch bigger.
The sum of two rational numbers will always be rational. A rational number is a number that can be expressed in the form a/b with b ≠ 0. So, if we can prove that the sum of two rational numbers has a denominator, we have proven this statement. Since any rational number can be written as a/b, we can write sum of two rational numbers as a/b + c/d. We can make this ad+bc/bd. Since we proved that the sum of two rational numbers has a denominator, we also prove that their sum is rational.
Since we have a rectangle triangle, then we can find the other side of the triangle using the Pythagorean theorem.
We have then:
Then the surface area is given by the sum of the areas.
Triangle of the base and the top:
Rectangle 1:
Rectangle 2:
Rectangle 3:
Finally, the surface area is:
Substituting values:
Answer:
The surface area of a right triangle prism is:
B. 132
Use a proportion.
2.2/5.5 = 48/x
2.2x = 5.5 * 48
2.2x = 264
x = 120
Answer: 120 ft
