Answer:
250
Step-by-step explanation:
250 ÷ 400 = 0.625 = 0.625 × 100/100 = (0.625 × 100)/100 = 62.5/100 = 62.5% Answer: Percentage of 62.5% of what number = 250?
The required number whose 62.5% is 2.25 is given as 3.6.
Given that,
To determine the number whose 62.5% is 2.25.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Given that,
Let the number be x,
According to the condition,
62.5% of x = 2.25
0.625x = 2.25
x = 2.25/0.625
x = 3.6
Thus, the required number whose 62.5% is 2.25 is given as 3.6.

This is an incredibly beautiful problem! It is solved mostly by algebra. r = 1 and the height will therefore be 2
Equations
l^2 + r^2 = l^2
l is the slant height.
Solution
SA = π * l * r + π r² = π(1 + √5) Divide both sides by π
Find l
l * r + r^2 = 1 + √5
l^2 = r^2 + h^2
l^2 = r^2 + (2r)^2
l^2 = 5r^2
l = √5 * r
Now go back to this equation to find r
l * r + r^2 = 1 + √5 Substitute the value for l
√5 r * r + r^2 = 1 + √5 On the left pull out r^2
r^2 (1 + √5) = 1 + √5 Divide by 1 + √5
r^2 = 1 Take the square root on both sides
sqrt(r^2) = sqrt(1)
r =1
Therefore h = 2

Form the diagram, you can see that UV is parallel to TS, this means that <UVS = < UTS
Given
<UVS = 5x + 38
<UTS = 12x - 28
Since the sum of opposite angle of a quadrilateral is 180 degrees, hence;
5x + 38 + 12x - 28 = 180
Collect like terms
5x + 12x - 28 + 38 = 180
17x + 10 = 180
17x = 180-1-
17x = 170
x = 170/17
x = 10
hence the value of x is 10

A car driving cross-country traveled 180 mites in 4 hours. At this rate of speed, how many mites further will the car travel in the next 3 hours?
Answer:
I'm sure you mean miles, but the car will travel 135 mites.
Step-by-step explanation:
(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

Let us take all the numbers one after the other
All numbers on numerator and denominator;
(4 * 9)/(2 * 4) = 9/2
All x
(x^2 * x^2)/(x^2 * x) = x
All y
(y^4 * y^4)/(y * y^9) = y^8/y^10 = 1/y^2
So the complete answer is;
9/2 * x * 1/y^2
= 9x/2y^2
All of the following represent the same function except _____.
y = x - 1

x y
1 0
3 2
5 4
8 7
Answer: {(0, 1), (2, 3), (4, 5), (7, 8)}
Step-by-step explanation:
For the function: y = x - 1 (y is one less than x)
If x =1 , y= 0
if x= 3 . y= 2
If x = 5 , y= 4
If x= 8 , y= 7
So it is same as
x y
1 0
3 2
5 4
8 7
But different from {(0, 1), (2, 3), (4, 5), (7, 8)} [here x is 1 less than y]
So, the complete statement would be : All of the following represent the same function except {(0, 1), (2, 3), (4, 5), (7, 8)} .

Table 1 and table 3 are represent linear functions of x.
What is a linear function?A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra.
Given are four tables, we need to find that which of them shows linear functions of x,
Linear functions will have the ratios of x and y coordinates, constant.
In table 1 :-
x/y = -1/2
-2/4 = -1/2
-3/6 = -1/2
Since the x and y coordinates are constant, therefore, the function is linear.
In table 2 :-
x/y = 1/1 = 1
2/4 = 1/2
3/9 = 1/3
Since the x and y coordinates are not constant, therefore, the function is not linear.
In table 3 :-
x/y = 1/5
2/10 = 1/5
3/15 = 1/5
Since the x and y coordinates are constant, therefore, the function is linear.
In table 4 :-
x/y = 1/1 = 1
2/8 = 1/4
3/27 = 1/9
Since the x and y coordinates are not constant, therefore, the function is not linear.
Hence, table 1 and table 3 are represent linear functions of x.
