Step-by-step explanation:

You want the product of (5/8a) and (3/7a).

The commutative and associative properties of multiplication help you find this product:

  [tex]\dfrac{5}{8}a\,\times\,\dfrac{3}{7}a = \left(\dfrac{5}{8}\cdot\dfrac{3}{7}\right)\times (a\cdot a)=\dfrac{5\cdot3}{8\cdot7}a^2=\boxed{\dfrac{15}{56}a^2}[/tex]

The expression 6wy-2wz+3xy-xz can be factorized into (2w+x) ( 3y-z). The value of a and b are 2 and 3 respectively

To factorize an algebraic expression, the highest common factors of the terms of the given algebraic expression are determined and then we group the terms accordingly. In another word, the reverse process of expansion of an algebraic expression is its factorization.

to factorize 6wy-2wz+3xy-xz , we firstly collect like terms, 6wy + 3xy -2wz - xz

The next step is to group the expression into two

(6wy+3xy)(-2wz-xz)

bringing out the factors in each parentheses

3y( 2w+x) -z(2w+z)

therefore 6wy-2wz+3xy-xz = (3y-z)(2w+z)

comparing the expression (aw+x)(by-z)

Therefore a = 2 and b= 3

The minimum cost per unit is obtained for an order of 8 units.

Since the total cost is modeled by;

We'll solve this by unitary method

The unitary method is a technique for solving a problem by finding the value of a single unit, I.e.,1,(by dividing), and then finding the necessary value by multiplying the single unit value.

C(x)=5x²+320

Then;

1 unit costs; C(x)=5(1)²+320 = 325

cost per unit 325/1 = 325

8 units costs; C(x)=5(8)²+320 = 640

cost per unit = 640/8 = 80

80 units costs; C(x)=5(80)²+320 = 32320

Cost per unit = 32320/80 = 404

The minimum cost per unit is obtained for an order of 8 units.

Find a particular solution of the following differential equations:

y" + 3y + 2y = –20 sin(2x)

Answer:

x = -19/7 z

z = -7/19 x

Lets solve for x in 21x + 39z = (7x+z):

Step 1: Add -7x to both sides.

21x+39z+−7x=7x+z+−7x

14x+39z=z

Step 2: Add -39z to both sides.

14x+39z+−39z=z+−39z

14x=−38z

Step 3: Divide both sides by 14.

14x/14 = −38z/14

x = −19/7 z

Lets solve for z in 21x 39z = (7z+z):

Step 1: Add -z to both sides.

21x+39z+−z=7x+z+−z

21x+38z=7x

Step 2: Add -21x to both sides.

21x+38z+−21x=7x+−21x

38z=−14x

Step 3: Divide both sides by 38.

38z/38 = −14x/38

z = −7/19 x

It is impossible to determine with certainty which number of pushups Bucky will never do in any game, as this depends on Bucky's physical abilities, training, and determination.

It is possible that Bucky may be able to do a very large number of pushups in a game, or he may not be able to do very many. It is also possible that there may be certain numbers of pushups that Bucky finds more challenging or difficult to do than others, but this would depend on his individual physical abilities and strengths.

Answer:

A quadrilateral is a parallelogram if and only if opposite angles are equal.

So, to make the quadrilateral a parallelogram, we can set the following equalities:

(4x + 13) deg = (5x - 12) deg

(4y + 7) deg = (3x - 8) deg

Solving the first equation,

4x + 13 = 5x - 12

x = -5

Solving the second equation,

4y + 7 = 3(-5) - 8

4y + 7 = -17

4y = -24

y = -6

So, the values of x and y that make the quadrilateral a parallelogram are x = -5 and y = -6

The range of probability is:

​c. ​zero to one

Probability is a measure of the likelihood of an event occurring. It is a value that ranges between 0 and 1, where 0 represents an impossible event, and 1 represents a particular event. In other words, a probability of 0 means that an event will not happen, and a probability of 1 means that an event will happen. Any probability value between 0 and 1 can be written as a decimal or a percentage. For example, a probability of 0.5 can also be written as 50%.

It is important to note that probability values cannot be negative or greater than 1. In probability theory, events that are impossible to happen have a probability of 0, and events that are certain to happen have a probability of 1. For example, a probability value of 0.5 means a 50% chance of an event and a 50% chance of it not happening. Therefore, the range of probability is between 0 and 1, as any value outside of this range would not be a valid probability.

Each student must work 14 hours on the project.

To solve this problem, we need to isolate the variable x on one side of the equation.

First, we can get rid of the fraction on the left side of the equation by multiplying both sides by 5:

5 * (x + 28) / 5 = 5 * (3x) / 5

This simplifies to:

x + 28 = 3x

Then, we can subtract x from both sides to get:

x + 28 - x = 3x - x

This simplifies to:

28 = 2x

Finally, we can divide both sides by 2 to find the value of x:

28 / 2 = 2x / 2

This simplifies to:

14 = x

The required measures of the angles of parallelogram ABCD as are follows m∠A = 66°,  m∠B = 114°, and m∠C = 66°.

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

Given parallelogram ABCD,

m∠D = 114°

In a parallelogram, the opposite angles are congruent, so m∠A is congruent to m∠C. This means that m∠A and m∠C have the same measure.

If m∠D = 114°, then m∠A must be equal to 180° - 114° = 66°, since the measures of the adjacent angles of a parallelogram add up to 180°.

So, m∠A = m∠C = 66°

So, m∠B = 114°

The diagonal length of the figure, to make sure the base of his tree house is a rectangle, is given as follows:

15 feet.

We want for the figure in this problem to represent a rectangle. For a rectangle, the diagonal is the hypotenuse of a right triangle in which the side lengths are the same as the side lengths of the triangle, and there is an angle of 90º between them.

Hence the Pythagorean Theorem can be used to obtain the diagonal, which states that the length of the hypotenuse squared is equals to the sum of each of the sides of the triangle squared.

Then the diagonal length is calculated as follows:

d² = 12² + 9²

d = square root (12² + 9²)

d = 15 feet.

The total number of girls and the total number of boys in the club are

number of girls = 58

number of boys = 25

The total number of girls and the total number of boys in the club is solved using the equation generated as follows

The number of girls in the Middle School Cyber Club was 8 more than double the number of boys

let the number of girls be x and the number of boys be y

x = 8 + 2y

total there were 83 middle school students in the Cyber Club

x + y = 83

substituting for x in x + y = 83

x + y = 83

plugging in x = 8 + 2y

8 + y + y = 83

8 + 2y = 83

solving for y

3y = 83 - 8

3y = 75

y = 25

solving for x

x = 8 + 2y

x = 8 + 2 * 25
