Answer:
3888pi cm^3 or 12214.5122372 cm^3
Step-by-step explanation:
To being, let's list out what we know
The volume of a sphere is
V = 4/3(pir^3)
But this is only half of a sphere, so the volume of it should be
V =2/3(pir^3)
With the diameter of the shape being
d = 36
We will first need to find the radius to use the formula above
r = d / 2
= 36 / 2
= 18
Now, let's start plugging in values
V = 2/3(pi18^3)
= 2/3 ( 5832pi)
= 3888pi or 12214.5122372

Answers
Answer:
47,1
Step-by-step explanation:
it is because when you multiply 3,14 by 15 you get your answer as 47,1 and it is a decimal
Using Multiplication, Jada need 47.1 feet of protective material around the rim of the pool.
What is multiplication?Multiplication is the "method of finding product of two or more numbers".
According to the question,
A circular swimming pool has a diameter of 15 feet.
In order to find how many feet of protective material jada need:
Formula for area of circle = πr² where 'r' is the radius of the circle.
Diameter = r²
= (3.14) (15) [π = .14]
= 47.1
Hence, Jada need 47.1 feet of protective material around the rim of the pool.

Select the correct answer. Which equation is true for the value a = 7? A. a + 2(a – 3) = 15 B. 4a – 4(14 – a) = 24 C. 2a + 47 = 105 D. 3a + 2(a – 3) = 34 E. 4a – 2a = 18
100 POINTS!!!!!!
Answers
Answer:
[A]. a + 2(a – 3) = 15
Step-by-step explanation:
To See which equation is true for the value a = 7 Solve all of it.
Start with [A]
[A] a + 2(a – 3) = 15
7+2(7-3)=15
Hence,this is True.
Next ,[B]
[B] 4a-4(14-a)=24
4(7)-4(24-7)= -40
Hence, this is False.
Then, we have [C]
[C] 2a + 47 = 105
2(7) + 47 =61
Hence, this is False.
Now, We have [D]
[D] 3a+2(a-3)=34
3(7)+2(7-3)=29
Hence, this is False.
Lastly, We have [E]
[E] 4a-2a=18
4(7)-2(7)=14
Hence, this is False.
Thus, Correct Answer = [A].a + 2(a – 3) = 15

A The length of a rectangle is 4 m more
than the width. The area of the rectangle
is 45 m2. Find the length and width.
Answers
Given :
The length of a rectangle is 4m more than the width.The area of the rectangle is 45m²⠀
To Find :
The length and width of the rectangle.⠀
Solution :
We know that,
[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\:[/tex]
So,
Let's assume the length of the rectangle as x and the width will be (x – 4).
⠀
Now, Substituting the given values in the formula :
[tex]\qquad \sf \: { \dashrightarrow x \times (x - 4) = 45 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 4x = 45 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 4x - 45 = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 9x+ 5 x - 45 = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow x(x - 9) + 5(x - 9) = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow (x - 9) (x + 5) = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow x = 9, \: \: x = - 5}[/tex]
⠀
Since, The length can't be negative, so the length will be 9 which is positive.
⠀
[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 9\:m}}}\:[/tex]
[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 9 - 4=5\: m}}}\:[/tex]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The length is 9m and the width is 5m.
What is a Rectangle?This is defined as is a quadrilateral with four right angles and the area is calculated as Length × width.
Let's assume length is x and width is (x-4).
We have x × (x-4) = 45m²
x² - 4x = 45
x² - 4x - 45 = 0
x² - 9x + 5x -45 = 0
x(x-9) +5 (x-9)
(x+5)(x-9) = 0
x = -5 or x = 9
x is therefore 9m and the width is (9-4) = 5m

Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models
Answers
Answer:
15% of 25
Step-by-step explanation:
Given the following questions:
25% of 15
15% of 25
We find the answer by using the formula to calculate percentage for both questions.
Question one:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{25\times15}{100} =25\times15=375\div100=3.75[/tex]
[tex]=3.75[/tex]
25% of 15 is 3.75
Question two:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{15\times 25}{100}=15\times25=375\div100=3.75[/tex]
[tex]=3.75[/tex]
15% of 25 is 3.75
Finally:
[tex]3.75=3.75[/tex]
[tex]15-3.75=11.25[/tex]
[tex]25-3.75=21.25[/tex]
[tex]11.25 < 21.25[/tex]
Which means 15% of 25 is "greater than" 25% of 15.
