What is the conversion of 2/5 in decimal ?
The conversion of a fraction number with denominator 5 and numerator 2 , 2/5 in decimals is equals to the 0.4 value.
A decimal number can be defined as a number whose whole number part and fractional part are separated by a decimal point. Writing 2/5 as a decimal number by converting the denominator to powers of 10. We multiply the numerator and denominator by a number so that the denominator is a power of 10.
2/5 = (2 × 2) / (5 × 2) = 4/10
Now move the decimal point to the left as many places as there are zeros in the denominator, which is a power of 10.
The decimal moved one place to the left because the denominator was 10. Therefore, 4/10 = 0.4. Hence, required value is 0.4.

Based on the function given, the slope of the function can be found to be 1.25.
How to find the slope?The slope of a function refers to the value that the dependent variable, x, changes by as a result of a unit change in the independent variable, y.
In a linear function, the slope is m as shown below:
y = mx + b
y = dependent variable
m = slope
x = independent variable
b = y- intercept
As seen above, the slope multiplies the independent variable which means that in the function, y = 5x + 3, the slope is 5.

Find the work W done by a force of 6 pounds acting in the direction 60\deg to the horizontal in moving an object 6 feet from(0,0) to (6,0)
The work done by the force of 6 pounds acting at an angle of 60 degrees to the horizontal in moving the object 6 feet is 18 foot-pounds.
To find the work done by a force of 6 pounds acting in the direction of 60 degrees to the horizontal in moving an object 6 feet from (0,0) to (6,0), we can use the formula for work:
Work (W) = Force (F) * Distance (d) * cos(θ)
Where:
Force (F) is given as 6 pounds
Distance (d) is the displacement of the object, which is 6 feet in this case
θ is the angle between the force vector and the displacement vector, which is 60 degrees in this case
Plugging in the values into the formula, we have:
W = 6 pounds * 6 feet * cos(60 degrees)
To calculate cos(60 degrees), we need to convert the angle to radians:
60 degrees = (60 * π) / 180 radians
= π / 3 radians
Now we can calculate the work:
W = 6 * 6 * cos(π/3)
Using the value of cos(π/3) = 0.5, we can simplify further:
W = 6 * 6 * 0.5
= 18

Prove by C/D formula that cos A + cos 2A + cos 5A = cos 2A (1 + 2 cos 3A)
We have proved the trigonometric expression cos A + cos 2 A + cos 5 A = cos 2 A (1 + 2 cos 3 A) by using C/D formula.
We are given the expression:
cos A + cos 2 A + cos 5 A = cos 2 A (1 + 2 cos 3 A)
We need to prove the expression.
We know that:
Cos C + Cos D = 2 cos ( C + D / 2) cos ( C - D / 2)
Using this identity, we get that:
= cos 5 A + cos A + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= 2 cos ( 5A + A / 2) cos ( 5A - A / 2) + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= 2 cos 3 A cos 2 A + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= cos 2 A ( 2 cos 3A + 1) = cos 2 A (1 + 2 cos 3 A)
= cos 2 A (1 + 2 cos 3 A) = cos 2 A (1 + 2 cos 3 A)
LHS = RHS
Hence proved.

Write an equation in slope-intercept form of the line that passes through the points (2, 4) and (3,6).
Answer:
\(y=2x\)
Step-by-step explanation:
We want to write an equation in slope-intercept form that passes through the points (2, 4) and (3, 6).
So, we will first find the slope. Let (2, 4) be (x₁, y₁) an let (3, 6) be (x₂, y₂).
The slope formula is given by:
\(\displaystyle m=\frac{y_2-y_1}{x_2-x_1}\)
So, by substitution, our slope is:
\(\displaystyle m=\frac{6-4}{3-2}=\frac{2}{1}=2\)
Now, we can use the point-slope form:
\(y-y_1=m(x-x_1)\)
By substitution:
\(y-(4)=2(x-(2))\)
Distribute:
\(y-4=2x-4\)
Adding 4 to both sides yields:
\(y=2x\)
And we have our equation.
In this case, the y-intercept is 0.

Answer:
x = 15
Step-by-step explanation:
\(12.45=4.95+0.5\timesx\)×x
Solve the equation
\(12.45=4.95+0.5x\)
Rearrange variables to the left side of the equation
\(-0.5x=4.95-12.45\)
Calculate the sum or difference
\(-0.5x=-7.5\)
Divide both sides of the equation by the coefficient of variable
\(x=\frac{-7.5}{-0.5}\)
Determine the sign for multiplication or division
\(x=\frac{7.5}{0.5}\)
Multiply both the numerator and denominator with the same integer
\(x=\frac{75}{5}\)
Cross out the common factor

If dy/dt=f(t)g(y), the equilibrium solutions can be obtained by finding the solutions to f(t)=0
The statement "If dy/dt=f(t)g(y), the equilibrium solutions can be obtained by finding the solutions to f(t)=0" is not entirely correct.
In a differential equation of the form dy/dt = f(t)g(y), the equilibrium solutions are the constant solutions where dy/dt = 0. These occur when g(y) = 0.
To find the equilibrium solutions, we need to solve g(y) = 0. Once we have found these solutions, we can determine their stability by analyzing the sign of f(t) near these equilibrium values. If f(t) is positive near an equilibrium value, the solution is unstable (i.e., solutions near the equilibrium will move away from it). If f(t) is negative near an equilibrium value, the solution is stable (i.e., solutions near the equilibrium will move towards it).
So, while f(t) = 0 may be useful in some cases for finding equilibrium values, it is not the correct approach for finding all equilibrium solutions in a differential equation of the form dy/dt = f(t)g(y). The equilibrium solutions are found by solving g(y) = 0.

lim x approaches infinity (2x-1)(3-x)/(x-1)(x+3) is
The limit of (2x-1)(3-x)/(x-1)(x+3) as x approaches infinity is 0.
To find the limit of the function (2x-1)(3-x)/(x-1)(x+3) as x approaches infinity, we will divide both the numerator and denominator through the highest power of x. In this case, the highest power of x is x², so we can divide both the numerator & the denominator through x²:
\([(2x-1)/(x^2)] * [(3-x)/((x-1)/(x^2)(x+3))]\)
Now, as x approaches infinity, every of the fractions within the expression procedures zero except for (2x-1)/(x²). This fraction techniques 0 as x procedures infinity because the denominator grows quicker than the numerator. therefore, the limit of the expression as x strategies infinity is:
0 * 0 = 0
Consequently, When x gets closer to infinity, the limit of (2x-1)(3-x)/(x-1)(x+3) is 0.

Mia takes 5/7 hours to deliver 100/1 news papers on her paper route whats is the eater per hour at which she delivers the news papers
Mia delivers newspapers at a rate of 140 papers per hour.
The correct answer is C.
To determine Mia's delivery rate, we need to calculate the number of newspapers she delivers per hour.
Mia takes \(\frac{5}{7}\) hours to deliver \(\frac{100}{1}\) newspapers.
We can convert the given fraction of time to hours by multiplying the numerator by 1 hour:
\(\frac{5}{7}\) hours = \((\frac{5}{7} )\times1\) hour
= \(\frac{5}{7}\) hour
Now, we can calculate Mia's delivery rate per hour by dividing the number of newspapers she delivers (100/1) by the time it takes her to deliver them (\(\frac{5}{7}\) hour):
Delivery rate = \(\frac{(\frac{100}{1} )}{\frac{5}{7}}\)
= \((\frac{100}{1} )\times(\frac{7}{5} )\)
= \(\frac{700}{5}\)
= \(140\)
Therefore, Mia delivers newspapers at a rate of 140 papers per hour.
The correct answer is C.

I have 4 times as many 10-cent stamps as 3-cent stamps. I have one less 2-cent stamp than 3 cent stamp. If I have b2-cent stamps, what is the value of my stamp collection in terms of b ?
Answer:
Value of stamp collection = (45b + 43) cents
Step-by-step explanation:
What we have here is as follows;
if there are x 3-cent stamps, then there are 4x 10-cent stamps
So the number of 2-cent stamps is 1 less than 3 cent stamps and that will be x-1 2 cent stamps
Number of 2 cents stamps = b
This means that x-1 = b
Thus, x = b + 1
So the value of the stamp collection is as follows;
x 3 cents stamps = 3(b+ 1) = 3b + 3 cents
4x 10 cents stamps = 10(4(b + 1)) = 10(4b + 4) = 40b + 40
value of the 2 cents stamp = 2b cents
Total value is thus;
2b + 40b + 40 + 3b + 3 = (45b + 43) cents
Answer:
45b + 43 cents
Step-by-step explanation:

From the diagram attached below, we can see the ratios of the sides of the triangle.
The question asks us to find the ratio of sin ∠X : sin ∠Z. To solve this, we have to know the definition of sine of an angle Θ:
\(\boxed{\mathrm{sin \theta = \frac{opposite}{hypotenuse}}}\).
For • ∠X: opposite side ⇒ YZ = 4
hypotenuse ⇒ XZ = 5
• ∠Z: opposite side ⇒ XY = 3
hypotenuse ⇒ XZ = 5
Therefore,
sin ∠X : sin ∠Z
= \(\frac{4}{5}\) : \(\frac{3}{5}\)
= 4 : 3 [Multiplying both sides by 5]
Therefore, the ratio sin ∠X : sin ∠Z = 4:3.
