Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models
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.

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.
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

Answer:
(a) 5 : 8 < 7 : 10
(b) 9/6 = 36/24
Step-by-step explanation:
(a)Perhaps simplest to explain is the use of a common denominator: 40.
[tex]5 : 8 = (5\cdot5):(8\cdot5)=25:40\\\\7:10=(7\cdot4):(10\codt4)=28:40\\\\25:40 < 28:40\quad\leftrightarrow\quad\boxed{5:8 < 7:10}[/tex]
__
Other ways you can do this comparison are ...
Multiply by 8·10 = 80, the product of the denominators:
5·10 = 50 < 7·8 = 56
Convert the fractions to decimal:
5/8 = 0.625 < 7/10 = 0.700
__
(b)Remove a factor of 4 from the second fraction:
[tex]\dfrac{9}{6}\text{ and }\dfrac{36}{24}\quad\leftrightarrow\quad\boxed{\dfrac{9}{6}=\dfrac{9\cdot4}{6\cdot4}}[/tex]
Write as a power of 3
[tex] \frac{ {3}^{n} }{ {9}^{n - 1} } [/tex]
Please help, many thanks
Answer:
3⁻ⁿ⁺²
Step-by-step explanation:
we need to make both bases the same
9 can be written as 3²
[tex] \frac{3 {}^{n} }{3 {}^{2(n - 1)} } [/tex]
multiply 2(n-1) = 2n - 2
[tex] \frac{3 {}^{n} }{3 {}^{2n - 2} } [/tex]
I'll rewrite as 3ⁿ ÷ 3²ⁿ⁻²
subtract the exponents when dividing numbers with the same base
n - (2n-2) or n - 1(2n-2) imagine the 1 is there
remember that the whole of (2n-2) is being multiplied by -1, so expanding
n - 2n + 2 = -n + 2
final answer: 3⁻ⁿ⁺²

which is 12 closer to?
7.5 or 15 ?
15 of course
Answer:
1
Step-by-step explanation:
12/15 = 0.8
0=0.0
1/2=0.5
1=1.0
0<0.5<0.8<1
So now it is in between 0.5 and 0.8 and it is closer to 1 as it is only 0.2 away, 0.5 is 0.3 away.

The cost to produce x units of wire is C=30x +500, while the revenue is R = 40x. Find the interval where the product will at least break even.
The break even point is the point where the cost and the revenue are equal
The break even point is at x = 50
How to determine the break even intervalThe functions are given as:
C(x) = 30x + 500 --- cost function
R(x) = 40x ---- revenue function
At the break even, we have:
R(x) = C(x)
So, the equation becomes
40x = 30x + 500
Subtract 30x from both sides
10x = 500
Divide both sides by 10
x = 50
Hence, the break even point is at x = 50

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.

8x9 = 9x8
2 x (1 x 9) = (2 x 1) (2 x 9)
(3 x 8) x 6 = 3 c (8 x 6)
1x 15 = 15
Answer: Choice C
(3 x 8) x 6 = 3 x (8 x 6)
=================================================
Explanation:
The associative property in general is
(a x b) x c = a x (b x c)
where the x stands for the multiplication symbol.
The a,b,c is in the same order for both sides, but grouped in slightly different ways with the parenthesis.
Plug in a = 3, b = 8, c = 6 to arrive at (3 x 8) x 6 = 3 x (8 x 6)

100 POINTS!!!!!!
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
