Answer:

2 4/5

Step-by-step explanation:

4/5 divided by 2/7 is 2.8. 2.8 in the form of a fraction is 2 4/5.

The fraction 4/5 divided by 2/7 in the simplest form, is 14/5.

Given that, (4/5) divided by (2/7).

To divide fractions, multiply the first fraction by the reciprocal of the second fraction

Let a, b, c and d be real numbers. Divide a fraction (a/b) by another fraction (c/d), we can multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of a fraction is obtained by swapping the numerator and denominator. So, the reciprocal of (c/d) is (d/c).

To divide (a/b) by (c/d), multiply the first fraction by the reciprocal of the second fraction:

(a/b) ÷ (c/d) = (a/b) x (d/c)

Multiplying the numerators and denominators:

(ad) / (bc)

Therefore, the result of (a/b) divided by (c/d) is (ad) / (bc).

To simplify this expression, and multiply the first fraction by the reciprocal of the second fraction:

(4/5) x (7/2)

Multiplying the numerators and denominators:

(4 x 7) / (5 x 2)

Simplifying the numerator and denominator:

28 / 10

To further simplify the fraction, and divide both the numerator and denominator by their greatest common divisor, which is 2:

28 ÷ 2 / 10 ÷ 2

This gives us:

14 / 5

Therefore, the fraction 4/5 divided by 2/7, in the simplest form, is 14/5.

Using trigonometric identity, sin(α + β) = -28/85.

To compute sin(α + β), we can use the trigonometric identity:

sin(α + β) = sin α cos β + cos α sin β

Given the values:

sin α = 15/17 (π/2 < α < 3π/2)

sin β = -4/5 (π < β < 3π/2)

To find sin α, we can use the Pythagorean identity:

cos α = ±√(1 - sin² α)

Since α is in the range π/2 < α < 3π/2, sin α is positive, so cos α will be negative.

sin α = 15/17

cos α = -√(1 - (15/17)²)

      = -√(1 - 225/289)

      = -√(64/289)

      = -8/17

Now, we can substitute the values into the formula for sin(α + β):

sin(α + β) = (sin α cos β) + (cos α sin β)

          = (15/17) * (-4/5) + (-8/17) * (-4/5)

          = -60/85 + 32/85

          = -28/85

Therefore, sin(α + β) = -28/85.

The question is incomplete:

Ava makes bead necklaces. She has a total of 6048 beads. Each necklace has 24 beads. Her friend maria says that the greatest number of necklace she can make with the beads is 162. Marias. Work is shown here. Explain why Maria is incorrect and how she can find the correct answer.

Answer:

Maria is incorrect because when you divide the number of beads by the beads in each necklace, you find that she can make 252 necklaces.

Step-by-step explanation:

You can find the number of necklaces Avan can make by dividing the number of beads she has by the amount in each necklace:

6048/24=252

According to this, you can say that Maria is incorrect because when you divide the number of beads by the beads in each necklace, you find that she can make 252 necklaces.

the answer is 30°

EXPLAINATION:

since the angle is a right angle triangle one of it's angles is 90°, and all the angles of a triangle always add up to 180°

so, 90° + 60° + x = 180

150° + x = 180°

so x = 180° - 150° = 30°

hence, the other acute angle is 30°.

The five-number summary for the given data is as follows: Minimum = 40, First Quartile = 51.5, Median = 69, Third Quartile = 86, Maximum = 95.

To obtain the five-number summary, we consider the minimum, first quartile, median, third quartile, and maximum values of the dataset.

Minimum: The smallest value in the dataset is 40.

First Quartile: The first quartile (Q1) is the median of the lower half of the dataset. To find Q1, we arrange the data in ascending order: 40, 46, 50, 55, 58, 61, 64, 69, 74, 79, 85, 86, 90, 94, 95. Since there are 15 data points, the median is the 8th value (69), which becomes the first quartile.

Median: The median is the middle value of the dataset. In this case, since we have an odd number of data points, the median is the 8th value (69).

Third Quartile: The third quartile (Q3) is the median of the upper half of the dataset. Again, using the ordered data, we find Q3 as the median of the values above the median (69). This gives us the third quartile of 86.

Maximum: The largest value in the dataset is 95.

Thus, the five-number summary for the given data is Minimum = 40, Q1 = 51.5, Median = 69, Q3 = 86, and Maximum = 95.

The partial sums will cease to change when the terms of the series become smaller than the smallest representable number in the floating-point system.

In floating-point arithmetic, there is a finite range of representable numbers and a limited precision for calculations. When dealing with infinite series, the terms are added or subtracted sequentially, but due to the limitations of numerical precision, there is a point at which the terms become too small to affect the sum significantly.

For the series 1/n, as n increases, the terms approach zero but never actually reach zero. Eventually, the terms become smaller than the smallest representable number in the floating-point system, and at this point, they essentially contribute zero to the sum. As a result, the partial sums of the series will cease to change beyond this point.

It's important to note that although the sum of the series may appear to be finite in floating-point arithmetic, mathematically, the series diverges and does not have a finite sum. The convergence to a finite value in floating-point arithmetic is a result of the limitations of numerical representation and precision. A divergent infinite series, such as the sum of 1/n from n=1 to infinity, can have a finite sum in floating-point arithmetic due to the limitations of numerical precision.

Step-by-step explanation:

The solution to the equation is x = 69.

To solve the equation 345 = 5x for x, we can isolate the variable by dividing both sides of the equation by 5:

345/5 = 5x/5

69 = x

Therefore, the value of x = 69.

This means that if we substitute x with 69 in the equation 5x, we will obtain the left-hand side of the equation 345. The solution is accurate to the hundredth place, as there are no decimal places involved in this particular equation. It's important to note that the solution is a whole number, and in this case, it represents the value of x that satisfies the equation.

Step-by-step explanation:

I hope this helped you out!!

Answer:

62.8

Step-by-step explanation:

Circumference is 2pi*radius. 2*pi*10 = 20 * 3.14 = 62.8

This equation represents the solution to the given initial value problem.

[tex]1/4 * e^{(4(y - 2))} = x + 1/4 * e^{(16)}[/tex]

To solve the initial value problem, we'll separate variables and integrate both sides.

Starting with the given differential equation:

[tex]dy/dx = e^{4(y - 2)}[/tex]

Separating variables:

[tex]e^{(4(y - 2))} dy = dx[/tex]

Integrating both sides:

[tex]\int e^{(4(y - 2))} dy = \int dx[/tex]

To integrate [tex]e^{4(y - 2)}[/tex], we can use the substitution u = 4(y - 2), du = 4dy:

[tex]1/4 \int e^u du = x + C[/tex]

Integrating [tex]e^u[/tex] gives us:

[tex]1/4 * e^u = x + C[/tex]

Substituting back u = 4(y - 2):

[tex]1/4 * e^{(4(y - 2))} = x + C[/tex]

Now, applying the initial condition y(0) = 6, we can solve for C:

[tex]1/4 * e^{(4(6 - 2))} = 0 + C[/tex]

[tex]1/4 * e^{(4(4))} = C[/tex]

[tex]1/4 * e^{(16)} = C[/tex]

Therefore, the solution to the initial value problem is:

[tex]1/4 * e^{(4(y - 2))} = x + 1/4 * e^{(16)}[/tex]

This equation represents the solution to the given initial value problem.

Answer:

(7, 3 )

Step-by-step explanation:

Given the 2 equations

x = 4y - 5 → (1)

2x + 3y = 23 → (2)

Substitute x = 4y - 5 into (2)

2(4y - 5) + 3y = 23 , that is

8y - 10 + 3y = 23

11y - 10 = 23 ( add 10 to both sides )

11y = 33 ( divide both sides by 11 )

y = 3

Substitute y = 3 into (1) for corresponding value of x

x = 4(3) - 5 = 12 - 5 = 7

solution is (7, 3 )
