The system of inequalities is:

x + y ≤ 10

x*$1.25 + y*$1.50 ≥ $24

And the graph can be seen below, on the graph, we can see that there are no solutions.

So we need to start by defining the variables we will be using, these are:

First, we know that Larissa wants to make at most 10 loaves of bread, then we can start with the inequality:

x + y ≤ 10

We also know that each banana bread sells for $1.25 and each but bread sells for $1.50, and she wants to make at least $24, then:

x*$1.25 + y*$1.50 ≥ $24

So the system of inequalities is:

x + y ≤ 10

x*$1.25 + y*$1.50 ≥ $24

So to graph these inequalities, we need to shade the region abovce the first line:

x + y = 10

and below the second line:

1.25*x + 1.50*x = 24

The graph of that system of inequalities can be seen below. The graph shows that the system has no real solutions (only has solutions for negative values of x).

Step-by-step explanation:

I guess you mean 1cm:100000cm

Hence, for every 1 cm on the map 100000 cm is covered on the land.

Take the distance on the map for 20 km be x

Hence, 1:100000:: x: 2000000 cm

In order to solve this ratio, you must multiply the extremes and the moderates (nears).

Hence, 2000000×1=100000×x [1km=100000 cm]

Hence, 2000000= 100000x

Hence, x=2000000/100000 cm

Hence, x=20 cm

Hence, 20 cm on the map

The angle x in the diagram is 98 degrees.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angle, alternate exterior angles, vertically opposite angles, same side interior angles etc.

Therefore, let's find the angle of x using the angle relationships as follows:

The size of the angle x can be found as follows:

82 + x = 180(same side interior angles)

Same side interior angles are supplementary.

Hence,

82 + x = 180

x = 180 - 82

x = 98 degrees

The zeros at the end of a number can be significant if it contains decimal point only if the digit next to or at the end of the number (of decimal point) is a significant number.

Significant numbers of a given number are those digits that can convey the meaning of the number or what it stands for (measures as) according to its accuracy.

All non-zero numbers are significant numbers irrespective of the fact where they are positioned, that is they can be positioned before or after a decimal (also before or after a zero).

All zeros are not significant numbers and whetehr they are to be called significant numbers or depend on the fact where they are positioned and whether they convey any meaning (or value ) of the number.

Answer:

(x-2)^2 + (y - 5)^2 = 16

Step-by-step explanation:

Given the standard form of an equation of a circle

(x-h)^2+(y-k)^2=r^2

If (h, k) = (5,2) and r = 4

Substitute

(x-2)^2 + (y - 5)^2 = 4^2

(x-2)^2 + (y - 5)^2 = 16

Hence the required equation is (x-2)^2 + (y - 5)^2 = 16

The metric unit from pounds to tons is 250 pounds = 0.125 tons

From the question, we have the following parameters that can be used in our computation:

250 pounds = how many tons

As a general rule, we have

1 pound = 0.0005 tons

Multiply both sides of the equation by 250

So, we have

250 * 1 pound = 0.0005 tons * 250

Evaluate the products

250 pounds = 0.125 tons

Hence, the conversion is 250 pounds = 0.125 tons

Answer:

Step-by-step explanation:

By comparing the intercepts of the linear equation with the ones in the graph, we conclude that the given graph corresponds with the linear equation.

Here we have the linear equation:

1.5*s + 3.5*c = 21

And we have a graph, which we want to see if it is the graph of the linear equation.

To check this, we just need to look at the intercepts, the variable "c" is on the vertical axis and the variable "s" is on the horizontal axis.

The "s" intercept is what we get when we take c = 0, replacing that we will get:

1.5*s + 3.5*0 = 21

1.5*s = 21

s = 21/1.5 = 14

This means that the line should pass through the point (14, 0), and we can see that this happens.

The other intercept is what we get when we take s = 0.

1.5*0 + 3.5*c = 21

c = 21/3.5 = 6

The other intercept is at (0, 6), which we also can see on the graph.

With that is enough to conclude that the given graph represents the given linear equation.

Answer:

The length will be 13 feet.

Step-by-step explanation:

Let the width be represented by w.

Based on the information given, the length will be:

= (2 × w) - 3

= 2w - 3

Therefore, the perimeter will be:

2(w) + 2(2w - 3) = 42

2w + 4w - 6 = 42

6w = 42 + 6

6w = 48

w = 48/6

w = 8

Therefore, the length will be:

L = 2w - 3

L = 2(8) - 3

L = 16 - 3

L = 13 feet

3. Segment Addition Postulate.

By the angle-angle similarity postulate, △YXZ∼△YZQ, and △YXZ∼△ZXQ.

The corresponding sides of two similar triangles are proportional.

Since similar triangles have proportional sides, therefore

\(\frac{a}{c}=\frac{f}{a}\) and \(\frac{b}{c}=\frac{b}{e}\)

Solving the equation for a² and b² gives

\(a^2=cf\) and \(b^2=ce\)

The value of a² is cf and the value b² is ce.

Adding these together gives

\(a^2+b^2=cf+ce\)

Factoring out the common segment gives

\(a^2+b^2=c(f+e)\)

From the given figure it is clear that

\(c=f+e\)

        (Segment Addition Postulate)

Using the Segment Addition Postulate, we get

\(a^2+b^2=c(c)\)

(a) The price is $18.

(b) The rate of change of demand with respect to price when x = 3 is 1/8 thousand units per dollar.

(c) The elasticity of demand when x = 3 is -3/4.

(a) When x = 3, the price, p can be computed by substituting the value of x in the given equation.

So, p = -2(3)² - 2(3) + 31 = -18 dollars

Price, p = $18.

(b) The demand function is given by:

p = -2x² - 2x + 31

Differentiate with respect to p.

dp/dp = d/dp(-2x^2 - 2x + 31)

Simplifying this, we get:

1 = -4x dx/dp - 2

Solving for dx/dp, we get:

dx/dp = (1 + 2)/(4x)

Substituting x = 3, we get:

dx/dp = 3/24 = 1/8

Therefore, the rate of change of demand with respect to price when x = 3 is 1/8 thousand units per dollar.

(c) To compute the elasticity of demand when x = 3, we use the formula:

E = (p/x) * (dx/dp)

Substituting x = 3 and dx/dp = 1/8 from parts (a) and (b), we get:

E = (p/3) * (1/8)

Substituting p = -18 from part (a), we get:

E = (-18/3) * (1/8) = -3/4

(6) Complementary angles          (7)Complementary angles

In geometry, special angles refer to specific angles that have special properties or characteristics. These angles include right angles, acute angles, and obtuse angles. A right angle is an angle that measures exactly 90 degrees, while an acute angle is an angle that measures less than 90 degrees. An obtuse angle, on the other hand, measures more than 90 degrees but less than 180 degrees. These angles are important in geometry as they form the foundation for many geometric shapes and concepts. Understanding the properties and characteristics of these special angles is crucial for solving geometry problems and constructing geometric figures accurately.

Special angles in geometry are specific angle measures that have unique properties and are often encountered in geometric problems. These angles include:

1. Right angle: A right angle is an angle that measures exactly 90 degrees. It is formed when two lines intersect perpendicularly.

2. Acute angle: An acute angle is an angle that measures between 0 and 90 degrees. It is smaller than a right angle.

3. Obtuse angle: An obtuse angle is an angle that measures between 90 and 180 degrees. It is larger than a right angle.

4. Straight angle: A straight angle is an angle that measures exactly 180 degrees. It is formed when two lines intersect in a straight line.

5. Reflex angle: A reflex angle is an angle that measures between 180 and 360 degrees. It is larger than a straight angle.

(5) All snow geese can eat for 11.5 days before the research and rescue center runs out of supplies.

What is snow geese?

Despite having a reputation for having white feathers, many snow geese are actually blue geese, which are darker, gray-brown birds. These birds were formerly believed to be two distinct species, however it has recently been discovered that they are actually just two color variants of the same bird. The variation in color is controlled by a single gene.

9 snow geese are housed in the research and rescue center.

Each geese consumed 16 ounces of seeds, therefore that's how much.

Therefore, the amount of seeds consumed by 9 snow geese is equal to (16*9) ounces.

144 ounces of seeds were consumed by 9 snow geese.

There are currently 1,656 ounces of seeds.

Thus, the number of days before the center runs out of food is equal to the sum of the ounces of seeds eaten by the nine snow geese divided by the total ounces of seeds.

Days till the food center runs out of supplies = 1656/144

11.5 days are required until the center runs out of food.

Hence, all snow geese can eat for 11.5 days before the research and rescue center runs out of supplies.
