percentage of 0.492?
Answer: 49.2%
Step-by-step explanation:0.492×100%
= 49.2%
How to convert decimal to percent
1 = 100%
The value V% in percent (%) is equal to the decimal value Vd times 100%:
V% = Vd × 100%
Examples
0.01 = 0.01 × 100% = 1%
0.05 = 0.05 × 100% = 5%
0.3 = 0.3 × 100% = 30%
0.35 = 0.35 × 100% = 35%

Answer:
Your answer would be 26.64cm.
A step-by-step explanation for you, peabrain:
For all four sides:
1.8cm x 2.7cm = 4.86cm
4.8cm x 4 sides = 19.44cm
For the top and bottom:
1.8cm x 1.8cm = 3.6
3.6cm x 2 sides = 7.2cm
For the complete LSA (lateral surface area):
19.44 + 7.2cm = 26.64cm
Do not forget to round, if that is in your homework instructions :-)!
Answer:
Solution given;
l=1.8cm
b=1.8cm
h=2.7cm
now
lateral surface area =2(lb+lh+bh )
=2( 1.8*1.8+1.8*2.7+1.8*2.7)
=25.92cm² is a required answer.
A research study comparing three treatments with n= 5 in each treatment produces T1= 5, T2= 10, T3= 15, with SS1= 6, SS2= 9, SS3=9, and EX= 94. For this study, what is SSbetween
Answer:
SSbetween is 10
Step-by-step explanation:
Given the data in the question;
A research study comparing three treatments with n = 5 in each treatment produce;
that is: n₁ = 5, n₂ = 5, n₃ = 5
T₁ = 5, T₂ = 10, T₃ = 15,
SS₁ = 6, SS₂ = 9, SS₃ = 9
∑x² = 94
First, we obtain the grand total;
G = T₁ + T₂ + T₃ = 5 + 10 + 15 = 30
N = n₁ + n₂ + n₃ = 5 + 5 + 5 = 15
Total SS = ∑x² - ( G²/N )
we substitute
Total SS = 94 - ( (30)²/ 15 )
Total SS = 94 - ( 900 / 15 )
Total SS = 94 - 60
Total SS = 34
To get the SSbetween or Between SS;
Between SS = ∑( T²/n ) - ( G²/N )
Between SS = ∑( (5)²/5 + (10)²/5 + (15)²/5 ) - ( (30)²/ 15 )
Between SS = ∑( 25/5 + 100/5 + 225/5 ) - ( 900 / 15 )
Between SS = ∑( 5 + 20 + 45 ) - 60
Between SS = 70 - 60
Between SS = 10
Therefore, SSbetween is 10

Your family's new business is finally starting to get on track. You started with an investment of $20,000, but lost 10% the first year, 6% the second year, and 3$ the third year. During the fourth year, however, you gained 5%
(A) How much money did you have after the first three years?
(B) What was the cumulative decay factor after the first three years?
(C) What was the cumulative factor after the first four years? Does this factor represent decay or growth?
(D) What percent increase do you need to get during the fifth year to break even (end up with $20,000)?
Answer:
A)
$16412.40.
B)
Our culminate decay factor was 0.82062.
C)
0.861651. It represents decay because it's less than one.
D)
We need at least a 16.1% increase.
Step-by-step explanation:
We started off with $20,000. In the first year, we lost 10%. In the second year, we lost an additional 6%, and another 3% in the third year. During the fourth year, however, we regained 5%.
Part A)
In the first year, we lost 10% of our original investment. In other words, we will have left 100% - 10% or 90% of our original investment. So, after the first year, we will have:
[tex]20000(0.9)=\$ 18000[/tex]
During the second year, we lost another 6%. So, it will be 100% - 6% = 94% = 0.94 of our current investment. So, after the second year, we will have:
[tex]18000(0.94)=\$ 16920[/tex]
Finally, during the third year, we lost 3%. So, it will be 100% - 3% = 0.97 of our current investment:
[tex]16920(0.97)=\$ 16412.4[/tex]
After the first three years, our investment dwindled down to $16412.40.
Part B)
We started off with $20,000 and ended up with $16412.40. Let r represent the decay factor. We can write the following equation:
[tex]20000d=16412.4[/tex]
This reads, "our original investment of $20,000 by multiplied by some (decay) factor equals our current investment of $16412.4."
Solve for d:
[tex]\displaystyle d=\frac{16412.4}{20000}=0.82062[/tex]
So, our decay factor is 0.82062.
(Note: This means that our rate of decay was 1 - 0.82062 = 0.17938. So, we lost approximately 18% of our investment over the course of the three years.)
Part C)
After the third year, our investment was $16412.40.
During the fourth year, we gained 5% on our investment. So, it will be 100% + 5% = 105% = 1.05 of our current investment:
[tex]16412.4(1.05)=\$ 17233.02[/tex]
Again, we can write an equation:
[tex]20000d=17233.02[/tex]
Where d represents the culminative factor after four years.
Solving for d yields:
[tex]d=0.861651[/tex]
Since the culminative factor is less than one, this is decay.
Decay is also correct contextually, since after four years, our current investment is lower than our original investment.
Part D)
After the fourth year, we have $17233.02.
In order to find the percent increase to rereach $20,000, we can write an equation:
[tex]17233.02d=20000[/tex]
Solving for d yields:
[tex]\displaystyle d\approx 1.1606[/tex]
So, the growth factor is about 1.1606.
This means that during the fifth year, we will need to grow by 1 - 1.1606 or about 16.1% in order to rereach our original investment of $20,000.

Given f(x) = x + 1 and g(x) = x^2, what is (g o f) (x)?
A. (g o f) (x) = x^2+x+1
B. (g o f) (x) = x^2+1
C. (g o f) (x) = (x + 1)^2
D. (g o f) (x) = x^2(x + 1)
Answer:(g o f)(x)=x^2+x+1
Step-by-step explanation:
It is Given f(x) = x + 1 and g(x) = x^2 therefore, the function (g o f) (x) is x^2 + x + 1.
What is function of functions and how are they represented?The function of function, as the name suggests, is functions applied over functions themselves. This is also called function composition.
We have input. We apply one function on that input. Then we apply another function on the output obtained by the first function. This whole function application on the first input is called the function of functions.
The resultant function which maps the input x to the final output is called the function of a function.
If the first function is g( and the other function is f, then we can write the resultant function of the function as
[tex](f\circ g)(x)[/tex]
where the x is the input to the first function.
Thus, we have;
[tex](f\circ g)(x) = f(g(x))[/tex]
It is Given f(x) = x + 1 and g(x) = x^2, we need to find (g o f) (x)
(g o f)(x) = g(x) + f(x)
= x^2 + x + 1

Step-by-step explanation:
cbhchchfvhvhshc;h
Answer:
456.73 cm²
Step-by-step explanation:
Area of a circle = πr²
The radius of the hub cap
= 75.74÷3.14÷2
= 12.06 cm (rounded to the nearest hundredth)
The area of the hub cap
= 3.14 × 12.06²
= 456.7314968152...
= 456.73 cm² (rounded to the nearest hundredth)
Circumference means the perimeter of a circle. So if the perimeter of a shape is smaller, it makes the shape turn out to be smaller.
So the area of the hub cap will be smaller.
A sprinter ran the 400 meter dash in 44.62 seconds. Convert her speed into miles per hour
Answer:
v = 20.7 mph
Step-by-step explanation:
Given that,
Distance, d = 400 m
Time, t = 44.62 s =
We need to find the speed of the sprinter. The speed of an object is defined as total distance covered divided by time taken. It can be given by :
[tex]v=\dfrac{d}{t}\\\\=\dfrac{0.248\ mile}{0.012\ s}\ (As\ 1\ m=0.000621371\ mile)\\\\=20.7\ mph[/tex]
Hence, the speed of the sprinter is equal to 20.7 mph.

Given a = 20, c=52, find b =
Answer:
b = 48
Step-by-step explanation:
a = 20
b = ?
c = 52
a^2 + b^2 = c^2
20^2 + b^2 = 52^2
400 + b^2 = 2704
b^2 = 2704 - 400
b^2 = 2304
sqrt(b^2) = sqrt(2304)
b = sqrt(2304)
b = 48

A right angle triangle has sides whose lengths are $2$-digit integers. The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides. Determine the smallest possible length of the hypotenuse.
Answer:
Smallest possible length of the hypotenuse = 65
Step-by-step explanation:
Given - A right angle triangle has sides whose lengths are $2$-digit integers. The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides.
To find - Determine the smallest possible length of the hypotenuse.
Proof -
The possible Pythagoras triplets of a right angled triangle with 2 digit integers are -
(11, 60, 61)
(12, 35, 34)
(13, 84, 85)
(16, 63, 65)
(20, 21, 29)
(28, 45, 53)
(33, 56, 65)
( 36, 77, 85)
(39, 80, 89)
(48, 55, 73)
(65, 72, 97)
But, Here Given that
The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides.
So, There is only one possibility that satisfy the condition.
and that is, (33, 56, 65)
So, we get
Length of one side = 33
Length of second side = 56
Length of hypotenuse = 65
So,
Smallest possible length of the hypotenuse = 65
