how mant cubic centimeters of air would be needed to completely fill a soccer ball with a radius of 15cm?
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.

A series contains 18 numbers and has a sum of 4,185. the last number of the series is 275. what is the first number? 42.5 190.0 465.0 740.0
The first term of the series if the series contains 18 numbers and has a sum of 4,185 is 190
Sequence and seriesSeries are sum of sequences
The formula for calculating the last term of a sequence is expressed as:
Sn = n/2(a+l)
Given the following
Sn = 4185
n = 18
l = 275
Required
first term "a"
Substitute
4185 = 18/2(a + 275)
4185 = 9(a + 275)
465 = a+ 275
a = 465 - 275
a = 190
Hence the first term of the series if the series contains 18 numbers and has a sum of 4,185 is 190

The average rate of change for the interval from x = 5 to x = 6 is - 22.
What is quadratic function?A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.
Since, the quadratic function has a vertex at (1, 2),
Hence, the equation for the function can be written in vertex form as:
⇒ y = a(x - 1)² + 2
Where "a" is a constant that determines the shape of the parabola. To find the value of "a", we can use one of the other points on the parabola.
Let's use the point (2, 1):
1 = a(2 - 1)² + 3
1 = a + 3
a = - 2
So, the equation for the quadratic function is:
y = -2x² + 2
Now we can use this equation to find the average rate of change between x = 5 and x = 6. The value of the function at x = 5 is:
y = - 2 x 25 + 2 = - 48
The value of the function at x = 6 is:
y = -2 x 36 + 2 = - 70
The average rate of change between x = 5 and x = 6 is:
(y₂ - y₁) / (x₂ - x₁) = (- 70 - (-48)) / (6 - 1) = - 22
Therefore, the average rate of change for the interval from x = 5 to x = 6 is - 22

Bruno will spin the arrow on the spinner 2 times. what is the probability that the arrow will stop on c at least once? 19 29 13 59
The probability that the spinner will land on c at least once is 5/9
How to determine the probability?From the complete question, the probability that the spinner will not land on c when spun twice is:
P = 4/9
Using the complement rule, the probability that the spinner will land on c at least once is:
P' = 1 - P
This gives
P' = 1 - 4/9
Evaluate
P' = 5/9
Hence, the probability that the spinner will land on c at least once is 5/9

Find (f•g) (x) if f(x)=3x^2 and g(x)=5-x
Answer:
f(g(x))=3x^2-30x+75
Step-by-step explanation:
We want to find the value of f(x) when x is equal to g(x)
So we can substitute the value of g(x) into the f(x) equation
f(g(x))= 3(5-x)^2
f(g(x))= 3(25-10x+x^2)
f(g(x))=3x^2-30x+75

A force of 61 N is applied to an area of 750 cm2.
Calculate the pressure in N/m2.
Give your answer to the nearest integer.
Answer:
813.33 N/m²
Step-by-step explanation:
Before finding the answer to this, let us convert 750cm² to m².
1 m ⇒ 100cm
1 m × 1 m ⇒ 100 cm × 100 cm
--------------
1 m² ⇒ 10000 cm²
x ⇒ 750 cm²
Let us use cross multiplication to find the value of x.
10000x = 750 × 1
10000x = 750
x = 750/10000
x = 0.075
∴ 750 cm² = 0.075 m²
And now let us find the pressure.
Pressure = Force ÷ Area
Pressure = 61 N ÷ 0.075 m²
Pressure = 813.33 N/ m²
