The area of the new shape formed by the two rectangles is calculated to be equal to 71 square centimeters.

The new shape will have a square region of 3 cm by 3 cm covered from one of the rectangles which will be under, so the area of the new shape is calculated as follows:

area of one identical rectangle = 8 cm × 5 cm

area of one identical rectangle = 40 cm²

area of the square region under = 3 cm × 3 cm

area of the square region under = 9 cm²

Area of the new shape = 40 cm² + (40 cm² - 9 cm²)

Area of the new shape = 40 cm² + 31 cm²

Area of the new shape = 71 cm²

Therefore, the area of the new shape formed by the two rectangles is calculated to be equal to 71 square centimeters.

Answer:

The GCF is 12. ^^

Step-by-step explanation:

Answer:

12(1+5)

Step-by-step explanation:

The gcf of 12 and 60 is 12. This is because both are divisible bt 12. 12/12=1 and 60/12 is 5. Since, they're both divisible by 12, take out the 12, and multiply it by it's factors. Since 12x1= 12 and 12x5=60, it would be 12(1+5)

a) The population is modeled by:

[tex]y = 13,500*(1.04)^t[/tex]

b) In the year 2008, the population is  18,476

The general population equation is an exponential equation of the form:

[tex]y = A*(1 + r)^{t}[/tex]

Where A is the initial population, r is the rate of growth, and t is the variable, time in years.

Here we know that the initial population is 13500, the rate is 4% (or 0.04 in decimal form).

Then the equation is:

[tex]y = 13,500*(1.04)^t[/tex]

b) 2008 is 8 years after 2000, so we need to evaluate in t = 8.

[tex]y = 13,500*(1.04)^8 = 18,475.68[/tex]

Answer:

[tex]m = \frac{ - 2 - 3}{5 - 1} = - \frac{5}{4} [/tex]

Answer:

The midpoint of segment AB is: M = ((-3 + 7)/2, (3 + (-7))/2) = (2, -2)

The slope of segment AB is: m = (y2 - y1)/(x2 - x1) = (-7 - 3)/(7 - (-3)) = -1

The slope of a line perpendicular to AB is the negative reciprocal of m: m_perp = -1/m = 1

The equation of the line passing through M with slope m_perp is: y - (-2) = 1(x - 2)

Simplifying, we get: y = x - 4

Therefore, an arbitrary point P(x, y) is on the perpendicular bisector of segment AB if and only if its coordinates satisfy the equation: y = x - 4

Answer:

y = x - 4

Step-by-step explanation:

To find the perpendicular bisector of the line segment AB, we first need to find the midpoint of AB. The midpoint M can be found using the midpoint formula:

M = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) = A and (x2, y2) = B

M = ((-3 + 7)/2, (3 - 7)/2) = (2, -2)

The slope of AB can be found using the slope formula:

m = (y2 - y1)/(x2 - x1)

m = (-7 - 3)/(7 - (-3)) = -10/10 = -1

The slope of the perpendicular bisector of AB is the negative reciprocal of the slope of AB. So, the slope of the perpendicular bisector is:

m_perp = 1/m = -1/-1 = 1

Now we have the midpoint M and the slope of the perpendicular bisector. We can use the point-slope form of a line to find the equation of the perpendicular bisector.

y - y1 = m(x - x1)

where m = 1 and (x1, y1) = (2, -2)

y + 2 = 1(x - 2)

y = x - 4

Therefore, the formula that expresses the fact that an arbitrary point P(x, y) is on the perpendicular bisector of segment AB with endpoints A(-3, 3) and B(7, -7) is:

y = x - 4

The maximum salary Larry can offer a new employee per annum is $250,000.

The maximum salary conferrable on a new employee is based on projections, worked out as follows:

The gross revenue to be generated = $8 million

Annual profit margin = 15% or $1.2 million ($8 million x 15%)

Current projected expenses for the year = $6.3 million

Actual cost of an employee = $0.5 million ($8 - 1.2 - 6.3)

Maximum salary = $250,000 ($0.5 million x 50%).

Thus, based on current projections of a gross revenue of 8 million USD with a 15% annual profit margin and projected expenses of 6.3 million, the maximum salary that Larry can offer a new employee is $250,000.

An equation that shows the cost of a pack of test tubes, t, in terms of the cost of a set of beakers is 10t = b - 4.

An equation with t and b that describes this situation is 8t + 12b = 348.

An equation that shows this substitution is 8t + 12(10t + 4) = 348.

The value of b is equal to $27.4.

The amount of money which the school paid for a set of beakers is $27.4 and $2.34 for a pack of test tubes.

In order to write a linear equation to describe this situation, we would assign variables to the cost of a pack of test tubes and the cost of a set of beakers respectively, and then translate the word problem into a linear equation as follows:

Since a pack of 10 test tubes costs $4 less than a set of nested beakers, a linear equation which can be used to model the cost of a pack of test tubes with respect to the cost of a set of beakers is given by;

10t = b - 4    .....equation 1.

For t and b, a linear equation which can be used to model the total cost is given by;

8t + 12b = 348      .....equation 2.

By making b the subject of formula in equation 1, we have;

b = 10t + 4

By substituting the value of b, we have;

8t + 12(10t + 4) = 348

8t + 120t + 48 = 348

128t = 300

t = 2.34

Answer:

To determine the scale factor used to create the image, we need to compare the corresponding side lengths of the original triangle ABC and the dilated triangle A'B'C'.

Let's take the side AB of triangle ABC and its corresponding side A'B' of triangle A'B'C'. The length of AB is 18-9=9 units, while the length of A'B' is 6-3=3 units. Therefore, the scale factor for the dilation from triangle ABC to triangle A'B'C' is:

scale factor = length of A'B' / length of AB = 3/9 = 1/3

So the answer is: the scale factor used to create the image is one third.

Step-by-step explanation:

The scale factor used to create the image triangle A'B'C' is 1/4.

To determine the scale factor used to create the image, we can compare the corresponding side lengths of the original triangle ABC and the resulting triangle A'B'C'.

Let's calculate the length of a side of triangle ABC and the corresponding side of triangle A'B'C':

Length of side AB in triangle ABC:

AB = √(12 - 4)² + (4 - 4)²

= 8

Length of side A'B' in triangle A'B'C':

A'B' = √(3 - 1)² + (1 - 1)²

=2

To find the scale factor, we can divide the length of the corresponding side in the image triangle (A'B'C') by the length of the corresponding side in the original triangle (ABC):

Scale factor = A'B' / AB

= 2 / 8

Answer: y = -3x + 5

Step-by-step explanation:

We are given that the line passes through the point (1,2) and has a slope of -3. To find the y-intercept, we can use the point-slope form of a line:

y - y1 = m(x - x1)

where (x1, y1) is the point the line passes through.

Substituting the values we have:

y - 2 = -3(x - 1)

Expanding the brackets and rearranging:

y - 2 = -3x + 3

y = -3x + 5

Therefore, the equation of the line is y = -3x + 5, in slope-intercept form.
