Answer: 5

Step-by-step explanation:

A = Lw (area of rectangle is length times width)

A = 15 (Area is 15)

L = 2x + 5 (length is 2 times a number plus another 5)

w = x - 4 (width is 4 less than that number

Plug in the values:

15 = (2x + 5)(x - 4)

FOIL

15 = 2x2 - 8x + 5x - 20

simplify:

15 = 2x2 - 3x - 20

Subtract 15

0 = 2x2 - 3x - 35

Factor out the quadratic. We know that one number has to be 7 and the other 5 so that they multiply together to make 35, and that one of them has to be negative so that it's actually -35.

That means we have m * n = -35

We also need it set up so that so that 2m + n = -3:

2 * -5 + 7 = -3

0 = (2x + 7)(x - 5)

So:

0 = 2x + 7, or 0 = x - 5

x = -7/2 or 5

We cannot have a negative length, so x = 5

Check:

15 = (2 * 5 + 5) (5 - 4)

15 = 15 * 1

15 = 15

The five-number summary of the class, determined by the results of the final test, is:

Joel cannot buy 2 games and 6 puzzles and satisfy the constraints was solved by using inequality.

The total cost of x puzzles and y games must be less than or equal to $96, which gives us the first inequality: 8x + 12y ≤ 96

The second inequality: x + y ≥ 9.

An inequality is a mathematical statement that compares two quantities or expressions and shows the relationship between them using one of the following symbols: <, >, ≤, or ≥. For example, "x > 5" is an inequality that states that x is greater than 5.

In the given question,

Part A:

Let x be the number of puzzles Joel can buy and y be the number of games Joel can buy.

The total cost of x puzzles and y games must be less than or equal to $96, which gives us the first inequality: 8x + 12y ≤ 96

Joel needs to buy at least 9 gifts, which means that the total number of gifts must be greater than or equal to 9. Since x represents the number of puzzles and y represents the number of games, the total number of gifts is x + y. This gives us the second inequality: x + y ≥ 9

We also know that Joel can only buy puzzles or games, not both. Therefore, x and y must be either both integers or both half-integers (such as 1.5 or 2.5), but they cannot be mixed. This gives us the third inequality:

x, y are both integers or both half-integers

Part B:

To see if Joel can buy 2 games and 6 puzzles and satisfy the constraints, we can substitute x = 6 and y = 2 into the inequalities:

8x + 12y ≤ 96

8(6) + 12(2) ≤ 96

72 ≤ 96

This inequality is true, so the first constraint is satisfied.

x + y ≥ 9

6 + 2 ≥ 9

8 ≥ 9

This inequality is not true, so the second constraint is not satisfied. Therefore, Joel cannot buy 2 games and 6 puzzles and satisfy the constraints.

The ordered pair (2,6) means that 2 plain rings and 6 initial rings were purchased, and the total cost would be 23 + 64 = 24 dollars.

In mathematics, an ordered pair is a collection of two objects, which are arranged in a specific order. The order of the objects in the pair is important, as the ordered pair (a, b) is different from the ordered pair (b, a) if a and b are not equal.

The two objects in an ordered pair can be anything, such as numbers, variables, or other mathematical entities. The ordered pair (x, y), for example, can represent a point on a two-dimensional coordinate plane, where x represents the horizontal coordinate and y represents the vertical coordinate.

The ordered pair notation is commonly used in set theory and other branches of mathematics to represent relationships between two objects. Ordered pairs can also be used to define functions, where the first object in the pair represents an input to the function, and the second object represents the output.

Here's the completed table and ordered pairs:

Cost of plain rings (x) Cost of initial rings (y) (Ordered Pairs (x,y))

              0                                 4                              (0,4)

               4                                 8                              (4,8)

In each ordered pair, the first number represents the number of plain rings purchased (x) and the second number represents the number of initial rings purchased (y). For example, the ordered pair (2,6) means that 2 plain rings and 6 initial rings were purchased, and the total cost would be 23 + 64 = 24 dollars.

Step-by-step explanation:

a) The speed at which the car gets maximum gas mileage is given as follows: 48 miles per hour.

b) The max gas mileage is given as follows: 29.5 miles per gallon.

The gas mileage is modeled as a function of the velocity x according to the quadratic function presented as follows:

m(x) = -0.028x² + 2.688x - 35.012.

The coefficients are given as follows:

a = -0.028, b = 2.688, c = -35.012.

The leading coefficient a is negative, hence the vertex represents the point at which the maximum mileage is obtained.

The velocity is given as follows:

x = -b/2a

x = -2.688/[2(-0.028)]

x = 48 miles per hour.

The max gas mileage is obtained as follows:

m(48) = -0.028(48)² + 2.688(48) - 35.012.

m(48) = 29.5 miles per gallon.

To calculate the total amount paid over two years, we first need to determine the annual premium increase percentage. Let's assume the insurer increases the premium by 5% per year to keep up with inflation.

After the first year, the new premium would be:

R450 + (5% of R450) = R472.50 per month

After the second year, the new premium would be:

R472.50 + (5% of R472.50) = R496.13 per month

To calculate the total amount paid over two years, we can use the following formula:

Total amount paid = (monthly premium x 12 months x number of years)

= (R450 x 12 x 2) + (R472.50 x 12 x 1) + (R496.13 x 12 x 1)

= R10,800 + R5,670 + R5,953.56

= R22,423.56

Therefore, you would have paid a total of R22,423.56 over two years.

The number 3 in the equation h(t) = -16t² + 6t+ 3 represents option 2 - the height from which the ball is thrown.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The equation h(t) = -16t² + 6t+ 3 gives the height of the ball as a function of time.

The constant term in this equation is 3, which represents the initial height of the ball when it is thrown.

Therefore, the correct answer is (2) the height from which the ball is thrown.

Option (1) cannot be correct, because the maximum height of the ball occurs when the derivative of h(t) is zero, which is not necessarily equal to the constant term in the equation.

Option (3) cannot be correct, because the ball reaches the ground when h(t) = 0, which requires solving a quadratic equation.

Option (4) cannot be correct, because the time it takes for the ball to reach its maximum height is given by the formula t = -b/2a, where a and b are the coefficients of the quadratic equation, and it does not depend on the constant term.

Therefore, option 2 is the correct answer.

We estimate that Jordan will drive a distance of approximately 4668.3 miles during the entire 7-day road trip.

Distance and displacement are two key words in mechanics that, although having similar sounds, have distinct definitions and meanings. How much of an object's path is covered by a moving object is measured in terms of distance. Whereas "How much route is covered by the item in a specific direction" is measured by displacement, The main distinction between distance and displacement is therefore that the former is a scalar quantity while the latter is a vector quantity.

Given that, the distance travelled is  666.9 miles.

The same distance is travelled for 7 days thus,

distance = Distance per day x Number of days

distance = 666.9 miles/day x 7 days

distance = 4668.3 miles

The formula for the perimeter of a triangle is expressed as;

P = a + b + c

Given that;

From the diagram shown, we have that;

Using the tangent identity;

tan 44 = BC/29

find the value and cross multiply

BC = 28. 00

Also, AC ²= 29² + 28²

AC = √1625 = 40. 3

Then, the perimeter = 29 + 28. 00 + 40. 3 = 97. 3 units

For the second diagram;

Note that the perimeter of a rectangle is expressed as 2(length + width)

Substitute the values

Perimeter =2 ( 4 + 3) = 14 units

For triangle;

sin 45 = 4/t

cross multiply

t = 5. 7 units

To determine the adjacent side;

5.7² - 4² = x²

The volume of Eli's trophy case is 64.4 cubic feet.

Eli's trophy case's length, breadth, and height must be multiplied to determine its volume. The case has the following measurements:

Length = 4 3/5 feet

Width = 2 feet

Height = 3 1/2 feet

We can sum the improper fractions after converting the mixed integers to fractions to arrive at:

Length = 4 3/5 feet = (5*4 + 3)/5 = 23/5 feet

Height = 3 1/2 feet = (2*3 + 1)/2 = 7/2 feet

Now that we have the volume, we can multiply the length, width, and height:

Volume equals length, width, and height

= (23/5) feet x 2 feet x (7/2) feet

= (23 x 2 x 7)/(5 x 2) cubic feet

= (644/10) cubic feet

= 64.4 cubic feet

Eli's trophy case therefore has a 64.4 cubic foot volume.

Therefore, 5 bakers can make 30 loaves of bread in 2 hours.

Therefore, 6 bakers can make 30 loaves of bread in 1.25 hours.

Therefore, 15 bakers can make 30 loaves of bread in 2 hours.

Step-by-step explanation:

In the number of bakers, it would take 2 hours to make 30 loaves of bread.

A proportion is an equation in which two ratios are set equal to each other.

Let h be the number of hours needed for a given number of bakers to make 30 loaves. Then we have:

2 bakers can make 30 loaves in 1 hour, so 1 baker can make 15 loaves in 1 hour.

Therefore:

3 bakers can make 45 loaves in h hours, so 45/3 = 15 loaves can be made in 1 hour. Thus, 3 bakers can make 30 loaves in 2 hours.

5 bakers can make 75 loaves in h hours, so 75/5 = 15 loaves can be made in 1 hour. Thus, 5 bakers can make 30 loaves in 2 hours.

6 bakers can make 90 loaves in h hours, so 90/6 = 15 loaves can be made in 1 hour. Thus, 6 bakers can make 30 loaves in 2 hours.

15 bakers can make 225 loaves in h hours, so 225/15 = 15 loaves can be made in 1 hour. Thus, 15 bakers can make 30 loaves in 2 hours.

Therefore, regardless of the number of bakers, it would take 2 hours to make 30 loaves of bread.

A math equation is a technique that links two statements and utilises the equals sign (=) to express equivalence. In algebra, an equation is a mathematical statement that proves the equivalence of two mathematical expressions. For example, in the computation 3x + 5 = 14, the equal sign inserts a gap between the numbers 3x + 5 and 14. A mathematical formula may be used to explain the link between the two phrases written on either side of a letter. The logo and the programme are usually the same. For example, 2x - 4 equals 2.

4x + 4y = 12 is obtained by multiplying the first equation by four.

To remove y, combine the first and second equations: (4x + 4y) + (4x - y) = 12 + 7, which simplifies to 8x = 19.

Divide both sides of the equation by 8 to find x: x = 19/8.

To find y, plug the value of x into either equation: y = 3 - x = 3 - 19/8 = 5/8.
