Answer:
14137.17 cubic cm
Step-by-step explanation:
I can see that the radius here is 15cm, and when it says air, I am going to guess we are looking for the volume. We do the equation in order to get the volume, and get the answer 14137.17cm.
IMPORTANT : When it says air- you have to realize it's VOLUME.
radius= 15 cm
to find:the amount of cubic centimeters of air needed to fill the soccer ball.
solution:[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]
[tex]v = \frac{3}{4} \times \pi \times {(15)}^{2} [/tex]
[tex]v = 14137.17 {cm}^{3} [/tex]
therefore, the soccer ball can hold 14137.17 cubic centimeters of air.

[tex]3\frac{3}{10}[/tex]
Step-by-step explanation:
Given: diameter = [tex]6\frac{3}{5}[/tex]
This is a mixed number.
We have to convert mixed numbers to improper fractions.
[tex]6*\frac{5}{5}+\frac{3}{5} \\ \frac{30}{5}+\frac{3}{5}=\frac{33}{5}[/tex]
diameter = 33/5
Now diameter = 2*radius so we divide 2 by diameter to get our radius.
[tex]\frac{33}{5} /2=\frac{33}{5}*\frac{1}{2} =\frac{33}{10}[/tex]
Improper fraction back to a mixed number.
10 can go into 33, 3 times so left with a 3 remainder.

y=mx+b (-6,-5) and (-4,-4)
Step-by-step explanation:
We will put this in y=mx +b form so first calculate the slope
m= (-4)-(-5)/(-4)-(-6)
m= 1/2. So y= x/2. +b
Now just substitute the x and y values of either given point to calculate b
I will use (-4,-4)
-4= (1/2)(-4) +b
-4= -2 +b
b=-2
So equation is y= x/2 -2

A rectangle has sides measuring (6x + 4) units and (2x + 11) units.
Part A: What is the expression that represents the area of the rectangle? Show your work.
Part B: What are the degree and classification of the expression obtained in Part A?
Part C: How does Part A demonstrate the closure property for polynomials?
Answer:
Down Here ↓↓↓
Step-by-step explanation:
Hello!
A)
The area of a rectangle is L * W.
Area = (6x + 4)(2x + 11)Area = 12x² + 8x + 66x + 44Area = 12x² + 74x + 44B)
The degree of a polynomial is the value of the highest exponent. The degree of 12x² + 74x + 44 is 2, because 2 is the highest exponent.
C)
This demonstrates the closure property, as adding, subtracting, and or multiplying polynomials will give a polynomial.
Rabbits can exhibit a number of colors in their coats: black, white, tan, brown, red, and grey. A disease randomly kills off most of the population and leaves only black and grey rabbits. Future generations are only black or grey. What is the term used to describe this phenomenon
Answer:
Genetic drift
Step-by-step explanation:
I took da test
The term used to describe this phenomenon of future generation fluctuations would be Genetic drift.
What is Genetic drift?Genetic drift refers to the random fluctuations in the number of offspring in a population.
Rabbits can exhibit several colors in their coats: black, white, tan, brown, red, and grey.
A disease randomly kills off most of the population and leaves only black and grey rabbits.
Future generations are only black or grey. We can see that the future rabbits have some common colors that are given by their parents.
So, this must be Genetic drift.

Bob's driveway is a rectangular shape with a length of 45 feet and a width
of 18 feet. Yolanda wants to find the area of Bob's driveway in yards. She
made sense of the problem by first finding the area of the driveway in feet
by doing 45(18) = 810 square feet. She then converted the area into yards
by doing 810(3). Her final answer was 2430 square yards. Did Yolanda

Write an equation to describe the sequence below. Use n to represent the position of a term in the sequence, where n=1 for the first term. 84, 168, 252, 336, ... an
Answer:
[tex]a_{n}[/tex] = 1 + (n-1)84
Step-by-step explanation:
to solve a sequence there's a formula-
[tex]a_{1}[/tex]+(n-1)d
where a1 is the first term, and d is the common difference
since we know the first term, and we have a few subsequent terms we can solve for d and creat the general formula for the nth term
to find d we simply check the difference between two terms-
168-x = 84
168-84 = x
84 = x
we can confirm this by checking the next two even
252- x = 168
252 - 168 = x
84 = x
now we have enough for a general formula
[tex]a_{n}[/tex] = 1 + (n-1)84

A. Zero product property
B. quadratic formula
C. square root property
The value of x by using the zero product property therefore option A is correct.
We have given that,
(x+3)(x+2)=0
we have to determine the technique that is most appropriate to use to solve each equation
What is the zero product property?The Zero Product Property simply states that if ab = 0, then either a = 0 or b = 0 (or both).
Therefore we have
(x+3)=0 and (x+2)=0
This implies that,
x+3=0
x=-3 and (x+2)=0 this implies that x=-2
Therefore we get the value of x by using the zero product property therefore option A is correct.

Find the equation of the circle in standard form.
center (5,-5)
radius = 3 units
Answer:
(x - 5)² + (y + 5)² = 9
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k ) = (5, - 5 ) and r = 3 , then
(x - 5)² + (y - (- 5) )² = 3² , that is
(x - 5)² + (y + 5)² = 9
