Answer:
See below
Step-by-step explanation:
Part A: The expression would be (4x+5)(3x+10), or, when expanded, 12x^2+55x+50 since the area of a rectangle is length*width
Part B: The degree is 2 because it's classified as a quadratic and trinomial expression
Part C: The closure property of polynomials is that polynomials will be closed under an operation if the operation produces another polynomial. For example, since we had to multiply two binomials in Part A, the exponents of x get combined to make x^2 (because x^1*x^1=x^(1+1)=x^2)
Answer:
757.35
Step-by-step explanation:
1. We assume, that the number 891 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 891 is 100%, so we can write it down as 891=100%.
4. We know, that x is 85% of the output value, so we can write it down as x=85%.
5. Now we have two simple equations:
1) 891=100%
2) x=85%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
891/x=100%/85%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 85% of 891
891/x=100/85
(891/x)*x=(100/85)*x - we multiply both sides of the equation by x
891=1.1764705882353*x - we divide both sides of the equation by (1.1764705882353) to get x
891/1.1764705882353=x
757.35=x
x=757.35
now we have:
85% of 891=757.35
The average volume if these eggs will be found as follows:
Volume of one egg is:
V=4/3πr²
V=4/3×π×(4.5/2)^3
V=71.57 cm³
Given that the turtle lays on average 113 eggs, thus the total volume of eggs will be:
(113×71.57)
=8187.41~8187 cm³
