The system of inequalities is 1.25x + 2y >= 375 and x + y <= 500, while the smallest number of chocolate covered almonds is 400

We make use of the following representations:

x = chocolate bars

y = chocolate covered almond

Using the above as a guide, and the given parameters;

We have:

1.25x + 2y >= 375 -- the amount raised

x + y <= 500 --- number of bars sold

From the question, we have

x = 100

Substitute x = 100 in x + y <= 500

100 + y <= 500

Evaluate

y <= 400

So, the least amount to sell is 400

To demonstrate that the diagonal slopes are opposing reciprocals, use the slope formula from coordinate geometry.

What is coordinate geometry?

The science of geometry using coordinate points is known as coordinate geometry (also known as analytical geometry).

Finding the difference between two points, breaking lines into m:n segments, locating a line's midpoint, computing a triangle's area in the Cartesian plane, and other operations are all feasible using coordinate geometry.

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

(x1,y1) =  coordinates of the line's first point

(x2,y2) = coordinates of the line's second point

Answer:

See below

Step-by-step explanation:

Use points given in hint to find slope, m  =  (2000 -1000) /( 6- 8) = -500

    then y = - 500x + b     sub i oneof the points to calculate b = 5000

so   y = - 500x + 5000    

if x = 7.5

      y = -500(7.5) + 5000 = 1250 dollars

Scott paid;

$13.24 for 3.41-pound bag of shrimp

This means,

$18.99 for 4.96-pound bag of shrimp

This means,

Therefore, the bag that is a better buy based on the unit price is the 4.96-pound because of the unit price which is lesser than the unit price for the 3.41-pound bag.

Thus, the 4.96-pound is a better buy.

We must write the ratio 7 to 15 and reduce it to the lowest term if possible.

The total cost of a Jacket is $124.75 and the cost of pair of sneaker is $74.75.

Let us say that the cost of the pair of sneakers is X dollars.

According to the given situation,

Cost of One jacket is 50 dollars more than the cost of a pair of sneakers.

Cost of one jacket = $(50 + X).

Total cost of one jacket and one pair of sneakers is $200.

Total cost of jacket and sneakers = $200

We get,

X + (X+50.5) = 200

2X + 50.5 = 200

The above equation that we have got is linear equation in one variable because it has degree 1 and one 1 variable.

Further solving the equation,

2X + 50.5 = 200

2X = 149.5

X = 74.75

So, the cost of one pair of sneakers is $74.75

Cost of One jacket is $(X + 50.5).

Cost of one jacket = $124.75.

So, one jacket costs $124.75 and sneakers cost $74.75.

The contrapositive of the statement is:

Jose isn't going for a bike ride if and only if he doesn't woke up early.

What is contrapositive?

A conditional statement's hypothesis and conclusion are switched, and both are then rejected, in a contrapositive. For instance, "if not B then not A" is the opposite of "if A then B." A conditional statement's contrapositive combines the inverse and converse.

The given statement is,

Jose wakes up early if and only if he is going for a bike ride.

We divide the statement into two parts.

1. Jose wakes up early.

2. He is going for a bike ride.

The negative of the statements are,

Jose doesn't wakes up early and he isn't going for a bike ride.

Therefore, the contrapositive of the statement is,

Jose isn't going for a bike ride if and only if he doesn't woke up early.

x³ is N²/15. The index form of a number is that digit written as an exponential expression or an unmarried number presented to another number.

A number's index form is that number written as an exponential expression or as a single number raised to another number. The exponent, or index, of an exponential expression indicates how many times the base must be multiplied by itself to evaluate the expression.

This fact can be used to write a number in index form. An index number is a number that has been multiplied by a power. The power, also known as the index, indicates how many times the number must be multiplied by itself. For example, 25 means multiplying 2 by itself five times

The distance between the points (−3, −5) and (−3, −7) is 2 units.

The distance formula gives the shortest distance between two points in a two-dimensional plane.

The distance formula is a useful tool for calculating the distance between two points.

Therefore,

d = √(x₂ - x₁)²+(y₂ - y₁)²

Let's find the distance between the points (−3, −5) and (−3, −7).

Hence,

x₁ = -3

x₂ = -3

y₁ = -5

y₂ = -7

d = √(-3 + 3)² + (-7 + 5)²

d = √(-2)²

d = √4

d = 2

Therefore, the distance between the point is 2 units.

From cosecant identity the expression cos(x)+sin(x)/ sin(x) =1+cot(x) was verified.

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.

The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.

The Pythagorean Theorem says: (hypotenuse)²= (leg1)²+(leg2)² . And the main trigonometric ratios are: sin (x) ,  cos  (x) and tan  (x) , where:

sin (x) = [tex]\frac{opposite\ leg}{hypotenuse}[/tex]

cos(x)=[tex]\frac{adjacent\ leg}{hypotenuse}[/tex]

tan (x) = [tex]\frac{\frac{opposite\ leg}{hypotenuse} }{\frac{adjacent\ leg}{hypotenuse} } = \frac{opposite\ leg}{adjacent\ leg}[/tex]

The question gives the following identity:  [tex]\frac{cos (x)+sin(x)}{sin(x)}[/tex]

First, you should rewrite the identity using the cosecant  identity -                          csc(x)= 1/sin(x) . Then,

(cos(x)+sin(x)) * csc(x)

After that, you should expand the previous expression.

cos(x)*csc(x) + sin(x)  * csc(x)

cos(x)*1/sin(x) + sin(x)  * 1/sin(x)

cos(x)/sin(x) + sin(x)/sin(x)

Is his answer reasonable: No, Emtiaz's answer is not reasonable because he assumed that the rate of descent was proportional.

The average rate of change is a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Next, we would determine the rate at which the skydiver falls per seconds:

Rate = time/distance

Rate = 100/0.8

Rate = 125

Also, an equation which models the height (h) of the skydiver at a 0.8 seconds is given by:

h = 125t

At 3.1 seconds, we have:

Rate = time/distance

Rate = 500/3.1

Rate = 161.3

At 1.5 seconds, we have:

Rate = time/distance

Rate = 187.5/1.5

Rate = 125

Therefore, the average rate of change at each time interval is not equal and as such Emtiaz's answer is not reasonable because the rate increases as the time increases.

Kaori taking a free throw is a guarantee. H(d) simulates the basketball's height (in meters) at d meters of horizontal separation from Kaori.

It is said that H(R) = 4H.

In this case, H(R) displays the height of a basketball instead of H(d). Therefore, it is evident that a basketball's height is 4H since H(R)=4H at d = R.

The horizontal distance from Kaori is R because d is the horizontal distance from Kaori.

Let's identify the coordinates of the initial and final triangle.

R = (-4, 5)

S = (-2, 5)

T = (-4, 1)

In the same way,

R' = (3, 2)

S' = (5, 2)

T' = (3, -2)

So, we can say that the translation was 7 units to the right and 3 units down, so the rule will be:

(x, y) ---> (x + 7, y - 3)

If we apply this rule to the points R, S, and T, we get:

R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)

R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)

R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)
