Step-by-step explanation:
We have,
The diameter of a basketball is 9.39 inches.
It is required to find the number of square inches of material used in constructing a basketball. It means we need to find the area of basketball. It is given by :
[tex]A=\pi r^2[/tex]
r is radius of basketball, r = 4.695 inches
So,
[tex]A=3.14\times (4.695)^2\\\\A=69.21\ \text{inches}^2[/tex]
So, the area of the basketball is [tex]69.21\ \text{inches}^2[/tex].

The store salsa jars have a height of ten centimeters and a radius of five centimeters. If there is only four centimeters of salsa left in the jar, then determine how much salsa is missing from the jar
Answer:
Step-by-step explanation:
The Salsa jar has a cylindrical shape. We would determine the volume of Salsa that the jar normally contains and the volume left in the jar by applying the formula for determining the volume of a cylinder which is expressed as
Volume = πr²h
Where
r = radius
π = 3.14
For normal volume,
h = 10 cm
r = 5 cm
Volume = π × 5 × 10 = 50π cm³
For volume left,
h = 4cm
Volume = π × 5 × 4 = 20πcm³
Missing volume = 50πcm³ - 20πcm³ = 30π cm³ = 30 × 3.14 = 94.2 cm³
Find the 96th term of the arithmetic sequence
-3, -14, -25, ...
Answer:
The 96th term of the given AP is (-1048)
Step-by-step explanation:
We have, the given AP is :
-3, -14, -25....
First term is -3
Common difference is -14 - (-3)= -11
Let [tex]a_{96}[/tex] is the 96th term of the AP.
The nth term of the AP is given by :
[tex]a_n=a+(n-1)d[/tex]
Put all the values, such that,
[tex]a_{96}=(-3)+(96-1)\times (-11)\\\\a_{96}=-1048[/tex]
So, the 96th term of the given AP is (-1048).

The perimeter of a square is 28 feet. What is its area
in square feet?
Answer:
A = 49 ft^2
Step-by-step explanation:
The perimeter of a square is given by
P = 4s where s is the side length
28 = 4s
Divide each side by 4
28/4 = 4s/4
7 =s
We want the area
A = s^2
A = 7^2
A = 49 ft^2
Which fraction is greater than 4/8 a.1/2 b.1/4 c.7/8 d.3/5
Answer:
c and d
Step-by-step explanation:
4/8 = 1/2
a.1/2 =1/2 so it is not greater
b.1/4 < 1/2 = 2/4 so 4/8 is greater
c.7/8 > 4/8 so 7/8 is greater
d.3/5 3/5 = 6/10 1/2 = 5/10
3/5 > 4/8
Answer: 7/8 and 3/5
Step-by-step explanation:
First, let’s look at 4/8 and 1/2. They have different denominations so let’s change them. 2 and 8’s closest multiple that they share is 8. 8/8=1, so we have to multiply the numerator and denominator by 1 which doesn’t change the fraction. 8/2=4, so we have to multiply the numerator and denominator by 4 which makes it: 4/8. 4/8 and 4/8 are the same so they are equal.
Next, let’s look at 4/8 and 1/4. They have different denominations so let’s change them. 4 and 8’s closest multiple that they share is 8. 8/8=1, so we have to multiply the numerator and denominator by 1 which doesn’t change the fraction. 8/4=2, so we have to multiply the numerator and denominator by 2 which makes it: 2/8. 4/8 is greater than 2/8 so this would be a wrong answer.
Then, let’s look at 4/8 and 7/8. They have the same denominations so we don’t have to change them. Let’s look at the numerators though: 4 and 7. 7 is greater than 4 so this answer would be correct.
Finally, let’s look at 4/8 and 3/5. They have different denominations so let’s change them. 5 and 8’s closest multiple that they share is 40. 40/8=5, so we have to multiply the numerator and denominator by 5 which makes it 20/40. 40/5=8, so we have to multiply the numerator and denominator by 8 which makes it: 24/40. 24/40 is greater than 20/40, so this answer is correct.
Hope this helps!

( i really need help )
Answer: 3.4
Step-by-step explanation:
V=4/3•pi•(r)^3
164.636=4/3•pi•(r)^3
164.636/(4/3•pi)= 39.3…

There are 130 people in a sports centre. 65 people use the gym 51 people use the swimming pool, 44 people use the track 15 people use the gym and the pool 14 people use the pool and the track 10 people use the gym and the track 1 person uses all 3 facilities A person is selected at random, what is the probability that this person doesn't use any facilities?
Answer:
Step-by-step explanation:
The Venn diagram representing the situation is shown in the attached photo.
G represents the set of people that use the gym.
P represents the set of people that use the swimming pool.
T represents the set of people that use the track.
Since 1 person uses the 3 facilities, it means that
Number of persons that use gym and pool only is 15 - 1 = 14
Number of persons that use pool and track only is 14 - 1 = 13
Number of persons that use gym and track only is 10 - 1 = 9
Number of persons that use gym only is
65 - (14 + 1 + 9) = 41
Number of persons that use pool only is
51 - (14 + 1 + 13) = 23
Number of persons that use track only is
44 - (9 + 1 + 13) = 21
N represents the number of people that use none of the facilities. Since there are 130 people in a sports centre, it means that
41 + 23 + 21 + 9 + 14 + 13 + 1 + N = 130
122 + N = 130
N = 130 - 122
N = 8
Therefore, the probability that a person doesn't use any facilities is
8/130 = 0.062
[tex]\frac{4}{65}[/tex] is the required probability.
What are sets?A set is an unorganized well-defined collection of similar types of objects.
Eg : {1,2,3,4,5} or {Science, Maths, English}
How to solve?Given:-
Total people (n) = 130
People using gym (G) = 65
People using swimming pool (P) = 51
People using track (T) = 44
(Gym U pool) = 15
(pool U track) = 14
(Gym U track) = 10
(Gym U track U pool) = 1
Using venn diagram :
Total participating people are 41 + 23 + 21 + 14 + 9 + 13 + 1 = 122
since total people are 130, non participants are 130 - 122 = 8
Probability of an event = [tex]\frac{favourable}{total}[/tex] = [tex]\frac{8}{130} = \frac{4}{65}[/tex]
Thus, the probability that a random person doesn't uses any facility is [tex]\frac{4}{65}[/tex]

A quadratic equation can be written in the form =(−ℎ)2+ y = a ( x - h ) + k , where (h, k) is the vertex of the parabola. This form can be used to determine the minimum y-value of the related function. Which is the minimum y-value of =52−20+24 y = 5 x 2 - 20 x + 24 ?
Answer:
(2,4)Step-by-step explanation:
The given function is
[tex]y=5x^{2} -20x+24[/tex]
Where [tex]a=5[/tex], [tex]b=-20[/tex] and [tex]c=24[/tex].
The vertex is at [tex](h,k)[/tex], which is defined as [tex]h=-\frac{b}{2a}[/tex] and [tex]k=f(h)[/tex]. So, replacing values, we have
[tex]h=-\frac{-20}{2(5)}=\frac{20}{10}=2[/tex]
Then, [tex]k=f(2)=5(2)^{2} -20(2)+24=5(4)-40+24=20-40+24=4[/tex]
So, the vertex is at [tex]V(2,4)[/tex].
Remember that the minium or maximum value of a quadratic function is defined by its vertex. In this case, it represents a minimum at (2,4).
What is the circumference of a circle with a diameter of 21cm, rounded to the nearest tenth
Answer:
Step-by-step explanation:
22/7 * 21 = 66cm
65.9 cm
Step-by-step explanation:
The formula for the circumference of a circle is...
[tex]C=\pi d[/tex]
Since the problem asks to round to the nearest tenth, we know that we will convert pi to 3.14. We also know the diameter is 21, so we can put both of these in the formula.
[tex]C=3.14*21[/tex]
C = 65.940
Rounded to the nearest tenth...
C = 65.9 cm
Ann replaces letters in the calculation KAN + GA - ROO with some of the numbers from 1 to 9 and then calculates the result. The same letters are replaced by the same numbers and different letters by different numbers. What is the largest possible result she can get?
Answer:
The largest possible result she can get is 550
Step-by-step explanation:
Here we have that to find the largest possible result, the numbers from which the last number is subtracted from should be the largest possible, hence
Whereby, we had K × A × N + G × A - R × O × O, then;
K ------- 9
A---------8
N---------7
G---------6
A---------8
R---------2
O---------1
O---------1
will give, 504 + 48 - 2 = 550
If however, the A = 7 and N = 8 we have;
504 + 42 - 2 = 544
Hence, the largest possible result she can get = 550.
