IS THE FRACTION 37/8 A RATIONAL NUMBER AND WHY
Option A)
Yes, Fraction 37/8 is a rational number because the decimal form of the number is terminal.
.
A Rational Number is any number that can be expressed as a fraction or ratio of two integers.
For example, 3/4, 8.75, 2, and -6 are all considered rational numbers.
Note that integers, or "whole numbers", are rational numbers. This is because they can be expressed as fractions.
For example, 2 can be rewritten as 2/1, or 200/100. -6 can be rewritten as -6/1, 6/-1, or -12/2.
Many non-integer, or decimal numbers, are also rational numbers.
For instance, 8.75 can be rewritten as 8 3/4, 875/100, or 1750/200. This also includes repeating decimal numbers like 0.3333333..., which can be rewritten as 1/3.
Fraction = 37 /8
Numerator = 37
Denominator = 8
Both are integer
The fraction of 37 divided by 8 = 37/8 is a Rational Number because both the numerator and denominator are integers.

I WILL GIVE BRAINLIST!!
Answer:
a=2s-b-c
Step-by-step explanation:
2s=a+b+c
a=2s-b-c
Answer:
2s-c-b =a
Step-by-step explanation:
s = ( a+b+c)/2
Multiply each side by 2
2s = ( a+b+c)/2 *2
2s = a+b+c
Subtract c from each side
2s -c = a+b+c-c
2s -c = a+b
Subtract b from each side
2s-c-b = a+b-b
2s-c-b =a

Answer:
1) -0.016 pounds per square inch per cubic inch.
2) [tex]\displaystyle V'(P)=-\frac{800}{P^2}[/tex]
Step-by-step explanation:
We are given the equation [tex]PV=800[/tex].
Part A)
We want to determine the average rate of change of P as V increases from 200 cubic inches to 250 cubic inches.
To find the average rate of change between two points, we find the slope between them.
Rewrite the given equation as a function of V:
[tex]\displaystyle P(V)=\frac{800}{V}[/tex]
Hence, the average rate of change for V = 200 and V = 250 is:
[tex]\displaystyle \begin{aligned} m &= \frac{P(250) - P(200)}{250 - 200} \\ \\ & = \frac{3.2 - 4}{250 - 200} \\ \\ & = -0.016\end{aligned}[/tex]
Therefore, the average rate of change is -0.016 pounds per square inch per cubic inch.
Part B)
We want to express V as a function of P. This can be done through simple division:
[tex]\displaystyle V(P)=\frac{800}{P}[/tex]
We want to show that the instantaneous change of V with respect to P is inversely proportional to the square of P. So, let's take the derivative of both sides with respect to P:
[tex]\displaystyle \frac{d}{dP}\left[V(P)\right]=\frac{d}{dP}\left[\frac{800}{P}\right][/tex]
Differentiate. Note that 1/P is equivalent to P⁻¹. This allows for a simple Power Rule:
[tex]\displaystyle \begin{aligned} V'(P) & = 800\frac{d}{dP}\left[ P^{-1}\right] \\ \\ & = -800(P^{-2}) \\ \\ & = -\frac{800}{P^2}\end{aligned}[/tex]
Therefore, the instantaneous change of V is indeed inversely proportional to the square of P.
Find the extreme values of f on the region described by the inequality.
f(x, y) = e−xy; x2 + 4y2 ≤ 1
Answer:f(x, y) = e
−xy. For the interior of the region, we find the critical points:
fx = −ye−xy
, fy = −xe−xy, so the only critical point is (0, 0), and f(0, 0) = 1.
For the boundary, we use Lagrange multipliers.
g(x, y) = x
2 + 4y
2 = 1 ⇒ λ∇g = h2λx, 8λyi, so setting ∇f = λ∇g we get
−ye−xy = 2λx and −xe−xy = 8λy. The first of these gives e
−xy = −2λx/y,
and then the second gives −x(−2λx/y) = 8λy ⇒ x
2 = 4y

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. There were twice as many large boxes shipped as small boxes shipped and the total weight of all boxes was 1435. Determine the number of small boxes shipped and the number of large boxes shipped.
Answer:
There were 7 small boxes and 14 large boxes shipped.
Step-by-step explanation:
This problem may be solved by a system of equations:
I am going to say that:
x is the number of small boxes used
y is the number of large boxes used
There were twice as many large boxes shipped as small boxes shipped
This means that y = 2x
Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. The total weight of all boxes was 1435 pounds.
This means that 45x + 80y =1435
So we have to solve the following system:
y=2x
45x + 80y =1435
45x + 80 (2x) = 1435
205x = 1435
x= 1435/205
x=7
y=2x= 2(7) = 14
There were 7 small boxes and 14 large boxes shipped.

express 7.84684846 as a rational number in the form p/q were p and q have no common factors
It's not clear what the pattern is supposed to be for the digits in the givne number. It looks like the repeating block should be 846, but it could just as easily be 84684.
Assume the first case, and let x = 7.846846846... . Then
1000x = 7846.846846846...
Subtract x from this to cancel the repeating decimal part, then solve for x :
999x = 7846 - 7 = 7839
x = 7839/999 = 871/111
If instead you meant the second case, let x = 7.846848468484684... . Then
10⁵ x = 784,684.846848468484684...
Solve for x :
99,999 x = 784,684 - 7 = 784,677
x = 784,677/99,999 = 261,559/33,333

2. Xandria rides through a jeepney which charges P 8.00 for the first 4 kilometers
and additional P0.50 for each additional kilometer. Express the jeepney fare (F)
as function of the number of kilometers (d) that Xandria pays for the ride.
Answer
Answer:
F(d) = 30 + 0.50d
Step-by-step explanation:
Given
Charges = P8.00 ---- first 4 km
Additional = P0.50
Required
Write a function to address the scenario.
Represent the whole distance covered with d.
First,we need to determine the total charges for the first four hours.
Charges = 8.00 * 4
Charges = 32.00
Next, we determine the charges for additional distance.
Charges = 0.50 * (d - 4)
d - 4 is the remaining distance after the first 4.
Charges = 0.50d - 2
The function is then written as;
F(d) = 32 + 0.50d - 2
F(d) = 32 - 2 + 0.50d
F(d) = 30 + 0.50d

how to solve this equation x²=16
Step-by-step explanation:
Hey there!
To solve this type of question, you must take square of variable"X" to right side making it ±squareroot. As it is a quadratic equation it will have two values (±).
Given;
[tex] {x}^{2} = 16[/tex]
Taking (square) to right side. It becomes ± square root.
[tex]x = + - \sqrt{16} [/tex]
[tex]x = + - \sqrt{ {4}^{2} } [/tex]
Cancel square and square root.
[tex]x = + - 4[/tex]
Therefore, X = ±4

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Step by step solution :
STEP
1 :
Trying to factor as a Difference of Squares:
1.1 Factoring: x2-16
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 16 is the square of 4
Check : x2 is the square of x1
Factorization is : (x + 4) • (x - 4)
Equation at the end of step

(x + 4) • (x - 4) = 0

2.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
2.2 Solve : x+4 = 0
Subtract 4 from both sides of the equation :
x = -4
Solving a Single Variable Equation:
2.3 Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4 and/or x=-4
Suppose that y varies directly with x, and y=3 when x=15
Find y when x=10
Answer:
yaa , when X=15, y = 3;
here the value of X is five times the value of y
so when X= 10
then. y =X/5 = 10/5= 2
so the value of y will be 2
