Jun Wei has a total of 40 coins. An algebraic expression or equation with the given information is formed to calculate the total number of coins.

An algebraic expression is the combination of one or more variables, coefficients, and constants separated by operators. Each of them is called terms of the expression.

Eg: a + 6x + 5y + 2

Here there are 4 terms with 3 variables, 3 coefficients, and one constant.

Given that,

Jun Wei has 12 more 10 cents coins than 20 cents coins.

So,

Consider the number of 20-cent coins = x

Then, the number of 10 cent coins = x + 12

It is given that the total value of all the coins is $5.40.

Where 1 $ = 100 cents. That implies, $5.40 = 540 cents

So,

the total value of the coins = 540 cents

⇒ 20(x) + 10(x + 12) = 540

⇒ 30x = 540 - 120

⇒ 30x = 420

∴ x = 40

Hence, there are 40 coins with Jun Wei.

7 lbs 8 oz more weight can the trolley hold the trolley can hold 20 lbs of groceries and Annie put 12 lbs 8 oz of groceries on the trolley. This can be obtained by converting the values to oz and subtracting them.

We know that, 1 lbs = 16 oz

Capacity of the trolley = 20 lbs

                                     = 20 × 16 oz

                                     = 320 oz

Weight put in the trolley = 12 lbs 8 oz

                                        = ( 12 × 16 ) + 8 oz  

                                        = 192+8 oz

                                        = 200 oz

Remaining weight that the trolley can hold = 320 oz - 200 oz

                                                                       = 120 oz

                                                                       = (7 × 16) + 8 oz

                                                                       = 7 lbs 8 oz

Hence 7 lbs 8 oz more weight can the trolley hold the trolley can hold 20 lbs of groceries and Annie put 12 lbs 8 oz of groceries on the trolley.

The equation of an ellipse for the graph shown is [tex]\frac{x^2}{5^2} + \frac{y^2}{21^2} = 1[/tex]

Since the given coordinates of the vertices and foci have the form (-5, 0) and (5, 0) and (-2, 0) and (2, 0) respectively, this ultimately implies that the major axis of this ellipse is the x-axis.

Thus, the standard form of the equation of this ellipse is given by:

[tex]\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1[/tex]

Next, we would solve for b² by using this equation:

b² = a² - c²

b² = 5² - 2²

b² = 25 - 4

b² = 21.

Substituting the parameters into the standard equation of an ellipse, we have;

[tex]\frac{x^2}{5^2} + \frac{y^2}{21^2} = 1[/tex]

Step-by-step explanation:

In the given diagram, the value of y is 53°

From the question, we are to determine the value of y

The angle subtended by the arc is 74°. This is the angle the arc subtends at the center of the circle.

Then,

74° + y + y = 180° (Sum of angles in a triangle)

74° + 2y = 180°

2y = 180° - 74°

2y = 106°

y = 106°/2

y = 53°

Hence, the value of y is 53°

The number, which on divided by 7 gives a quotient of 247 and a remainder of 3 is 1732. Computed using linear equations.

In the question, we are informed that a number when divided by 7, gives a quotient of 247 and a remainder of 3.

Assuming the number to be x.

We can say that x is our dividend, 7 is the divisor, 247 is the quotient, and 3 is the remainder.

The division algorithm equation is:

Dividend = Divisor*Quotient + Remainder,

Substituting values in this equation, we get a linear equation:

x = 7*247 + 3.

To solve for the unknown number x, we solve the equation as follows:

x = 7*247 + 3,

or, x = 1729 + 3,

or, x = 1732.

Thus, the number, which on divided by 7 gives a quotient of 247 and a remainder of 3 is 1732. Computed using linear equations.

2. If ab = 0, then a = 0 or b = 0. This statement is true. It is a property of the real numbers which was stated in class

Answer:

(9, 6)

Step-by-step explanation:

the given points are

(3, 2)

(6, 4)

so, can you see, how the sequence continues ?

I see immediately that for every 3 additional units of x we add 2 units of y.

so, yes, the next point in the sequence is

(6 + 3, 4 + 2) = (9, 6).

so, this point (or ordered pair) follows the same ratio or proportional relationship between x and y as the points already in the graph.

in other words, they are on the same line following the same slope ("y coordinate change / x coordinate change" when going from one point on the line to another).

Answer:

A

Step-by-step explanation:

an arithmetic sequence is a sequence that is increasing or decreasing by a constant number (addition)

The correct answer is option A which is ABCD ≅ A'B'C'D'.

The process of changing the location of the image on the coordinate system will be known as the translation.

Quadrilateral ABCD is rotated at 145° about point T. The result is quadrilateral A'B'C'D'.

ABCD ≅ A'B'C'D'is correct Since the quadrilateral remains the same even after rotation of 145 degrees. Its corresponding sides and angles will remain the same.

Thus ABCD is congruent to A'B'C'D'.

Answer: 0.001389

Step-by-step explanation:

Since you have 6 probabilities that it could be red, you get 1/6. Now, you took 1 probability out of 6, so now you only have 5. So you multiply 1/6 by 1/5. Now you have only 4 cards. Multiply 1/ 6 * 1/5 * 1/4 and keep going (e.g 1/6 * 1/5 * 1/4 * 1/3 * 1/2 * 1). This comes out to 0.00138888888, or rounded to six decimal places, 0.001389.

The simplified expression that represents the total perimeter of the triangle is 2x^2 + 10x  + 3

The side lengths are given as:

2x^2 + 5x + 3, 2 + 2x and 3x - 2

Add these lengths to determine the perimeter (P)

P = 2x^2 + 5x + 3 + 2 + 2x + 3x - 2

Collect like terms

P = 2x^2 + 5x + 2x + 3x  + 3 + 2 - 2

Evaluate the like terms

P = 2x^2 + 10x  + 3

Hence, the simplified expression that represents the total perimeter of the triangle is 2x^2 + 10x  + 3
