How do you compare fractions with like numerators?
To compare fractions with like numerators always compare denominators.
We can calculate the LCM of the numerators and then multiply the numerators by the corresponding values to make the numerators of two or more fractions the same or similar. If the numerators are similar or the same, comparisons become simple. Verify the denominators of fractions with comparable or identical numerators. The fraction decreases as the denominator increases. They are referred to as having like or the same numerators when two or more fractions have the same numerators but distinct denominators. While they are referred to as having like or the same denominators when the denominators of two or more fractions are the same.

Arjun begins the calendar year with $4000 in his bank account. he earns 9% simple interest annually. after how many years will the valance of the account be $6500?
The number of years that it will take for the Valence of the account to be $6500 = 6.9 years
What is annual simple interest?Annual simple interest is defined as the amount of money that is being paid to an individual who invested a specific amount of money for a period of time.
The principal amount = $4000
The rate for earnings= 9%
The simple interest= $6500 - 4000 = 2500
Time = X
Using the formula:
Simple interest = P ×T×R/100
Make T the subject of formula;
T = Simple interest × 100/ P × R
T = 2500 × 100/ 4000× 9
T = 250000/36000

Let R(s, t) = F(u(s, t), v(s, t)), and assume the following are true.
u(1, 0) = 2
us(1, 0) = −2
ut(1, 0) = 6
v(1, 0) = 3
vs(1, 0) = 5
vt(1, 0) = 4
Fu(2, 3) = −1
Fv(2, 3) = 10
Find the values below.
Rs(1, 0) =
Rt(1, 0) =
Answer:
To find Rs(1,0) and Rt(1,0), we need to use the chain rule of partial differentiation.
Rs(1,0) can be found by computing the partial derivative of R with respect to s, while holding t constant and then evaluating the result at (1,0). Similarly, Rt(1,0) can be found by computing the partial derivative of R with respect to t, while holding s constant and then evaluating the result at (1,0).
Using the chain rule, we have:
Rs = Fu * us + Fv * vs
Rt = Fu * ut + Fv * vt
We are given the values of u, v, us, ut, vs, vt, Fu, and Fv at the point (1,0) and the values of u and v at the point (2,3). We can use these values to compute Rs(1,0) and Rt(1,0) as follows:
Rs(1,0) = Fu(2,3) * us(1,0) + Fv(2,3) * vs(1,0)
= (-1) * (-2) + (10) * (5)
= 52
Rt(1,0) = Fu(2,3) * ut(1,0) + Fv(2,3) * vt(1,0)
= (-1) * (6) + (10) * (4)
= 34
Therefore, Rs(1,0) = 52 and Rt(1,0) = 34
find the area of the figure below:
The area of the figure is 71 in².
The area can be found by noticing that the figure is a rectangle with a triangular section taken out from the corner (see attached figure). You can use this information to easily find the shape's area.
To find the area of the original rectangle, before the triangle was taken away, multiply its length and width together: This gives you the area of the rectangle, in in².
Next, we need to find the area of the small triangle. Using the information given, you can find that this triangle has side lengths of 4 and 5. The area of a triangle can be found by multiplying its base times its height, then dividing this value by two. Doing so for this triangle gives us:
in².
Now that we know the areas of both shapes, simply subtract the area of the triangle from the area of the rectangle: 81 in² - 10 in² = 71 in², which is the area of the entire shape.

Find the volume of the described solid of revolution or state that it does not exist. The region bounded by f(x) = (x - 1)^-1/4 and the x-axis on the interval (1, 6] is revolved about the x-axis. Set up the integral that should be used to find the volume of the solid. Use increasing limits of integration. (Type exact answers.) Find the volume or state that it does not exist. Select the correct answer and, if necessary, fill in the box to complete your choice. A. The volume is cubic units. (Type an exact answer.) B. The volume does not exist.
The correct option is A. The volume is 6.77 cubic units
The function and interval given are f(x) = (x - 1)^-1/4 and the x-axis on the interval (1, 6].
We want to find the volume of the solid of revolution when the region is rotated about the x-axis.
Let's consider the graph of the function: graph{(x-1)^(-1/4) [-10, 10, -5, 5]}
To set up the integral to find the volume of the solid of revolution, we can use the disk method.
We need to integrate the area of each disk perpendicular to the x-axis from x = 1 to x = 6.
The area of a disk is given by the formula: A = πr²
where r is the radius of the disk and is equal to f(x) in this case.
Therefore, the area of a disk is: A = πf(x)²
Let's substitute f(x) into this formula and integrate from x = 1 to x = 6 to get the volume of the solid.
We have The integral that should be used to find the volume of the solid is given as:
V = ∫₁⁶ πf(x)² dx
We substitute f(x) = (x - 1)^(-1/4) into this expression and integrate to get the volume.
We have: V = ∫₁⁶ π(x - 1)^(-1/2) dx
Let u = x - 1, so that du/dx = 1 and dx = du.
When x = 1, u = 0, and when x = 6, u = 5.
Therefore, we have: V = ∫₀⁵ πu^(-1/2) du= 2π[u^(1/2)]₀⁵= 2π(√5 - 1) ≈ 6.77 cubic units.
The volume of the solid of revolution when the region is rotated about the x-axis is approximately 6.77 cubic units.
Thus, the correct option is A. The volume is 6.77 cubic units.

Answer:
g = \(\frac{4}{3}\)
Step-by-step explanation:
4 - \(\frac{1}{12}\) g - 2 = \(\frac{3}{2}\) g + 1 - \(\frac{5}{6}\) g
multiply through by 12 ( the LCM of 12, 2 and 6 ) to clear the fractions
48 - g - 24 = 18g + 12 - 10g
- g + 24 = 8g + 12 ( subtract 8g from both sides )
- 9g + 24 = 12 ( subtract 24 from both sides )
- 9g = - 12 ( divide both sides by - 9 )
g = \(\frac{-12}{-9}\) = \(\frac{12}{9}\) = \(\frac{4}{3}\)

The average velocity of Gwen over the time interval 0 < t is zero. We need to solve the equation:250sin(πt/45) = 0Solving for t, we get:πt/45 = nπwhere n is an integer.
Given that Gwen runs back and forth along a straight track and her velocity, in feet per second, is modeled by the function v(t) during the time interval 0 < t < 45 seconds; We are to determine the first time at which Gwen changes direction and find her average velocity over the time interval 0 < t.Firstly, we know that velocity is a vector quantity and has both magnitude and direction.
Since she is running back and forth along a straight track, her displacement at any given time t is given by the function s(t), which is the integral of her velocity function v(t).That is, s(t) = ∫v(t)dtWe can find the displacement by taking the definite integral of v(t) from 0 to t. Since Gwen is running back and forth, her displacement will be zero at the times when she changes direction.
Therefore, we need to solve the equation:250sin(πt/45) = 0Solving for t, we get:πt/45 = nπwhere n is an integer. Therefore,t = 45n/πwhere n is an integer. Since we are looking for the first time at which Gwen changes direction, we need to take the smallest positive value of n, which is n = 1.

A. 10-4
B. 102
C. 106
D. 10-2
E. 104
The quantity 1.0 mg/cm2 is the same as 1.0 x 10-4 kg/m2.
To convert from milligrams per square centimeter (mg/cm2) to kilograms per square meter (kg/m2), we need to use conversion factors to adjust the units. The given options represent different powers of 10 that can be used as conversion factors.
We know that 1 kilogram (kg) is equal to 1,000,000 milligrams (mg), and 1 meter (m) is equal to 100 centimeters (cm). Therefore, we can express the conversion factors as follows:
1 kg = 1,000,000 mg (1)
1 m2 = 10,000 cm2 (2)
To convert from mg/cm2 to kg/m2, we can combine these conversion factors:
1 mg/cm2 = (1 mg / 1 cm2) x (1 kg / 1,000,000 mg) x (10,000 cm2 / 1 m2)
Simplifying the expression, we have:
1 mg/cm2 = (1 / 1,000,000) kg/m2 = 1 x 10-6 kg/m2
Therefore, the quantity 1.0 mg/cm2 is the same as 1.0 x 10-6 kg/m2.
Among the given options, the value that matches the conversion is option A: 10-4

Find the missing length of the triangle. A right-angled triangle with its opposite side labeled 0.3 centimeters, adjacent side labeled b, and hypotenuse labeled 0.5 centimeters.
The missing length of the triangle can be found using the Pythagorean Theorem which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We can use the formula c² = a² + b² where c is the hypotenuse, a is the opposite side and b is the adjacent side.
To find the missing length, we can rearrange the formula to solve for b: b² = c² - a². Substituting the given values,
we have: b² = (0.5)² - (0.3)².
Simplifying the equation, we get: b² = 0.16.
Taking the square root of both sides, we get: b = 0.4 cm.
Therefore, the missing length of the triangle is 0.4 centimeters.
