Answer:

192 feet of fabric

Step-by-step explanation:

Since each curtain needs to be 36 inches long, or 3 feet long, the total length of fabric needed for one curtain is 3 feet. To make 64 curtains, Ivania's curtain company will need a total of:

3 feet/curtain x 64 curtains = 192 feet of fabric

The number of feet of fabric that Ivania needs to make the curtains is 192 feet.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Given that,

Ivania's curtain company is making curtains for a local hotel.

Length of each curtain needed = 36 inches

                                                    = 36/12 feet

                                                    = 3 feet

At the fabric store, fabric is sold by the foot.

Number of curtains needed to make = 64

We have to multiply the length of each curtain with the total number of curtains to find the total length of the curtain needed.

Feet needed = 64 × 3 feet = 192 feet

Hence the feet of curtains needed is 192 feet.

The feasible region is the area below the line x+3y=9, below the line 3x+y=9, and to the right of the y-axis and the bottom of the x-axis.

What are the steps to make the graph for the feasible region?

To graph the feasible region, we first graph the boundary lines of the inequalities.

To graph the line x + 3y = 9, we can first find its intercepts by setting x = 0 and y = 0:

When x = 0,

3y = 9, so y = 3

When y = 0, x = 9

So the line passes through the points (0, 3) and (9, 0).

To graph the line 3x + y = 9, we can again find its intercepts:

When x = 0, y = 9

When y = 0,

3x = 9, so x = 3

So the line passes through the points (0, 9) and (3, 0).

Now we can shade the region that satisfies all the inequalities, which is the region below the line x + 3y = 9, below the line 3x + y = 9, and to the right of the y-axis and the bottom of the x-axis (since x and y must both be greater than or equal to 0).

By answering the presented question, we may conclude that As a result, slope the correct answer is y = (4/5)x + 23/5.

The slope of a line indicates how steep it is. The term "gradient overflow" refers to a mathematical equation for the gradient (the change in y divided by the change in x). The slope is defined as the ratio of the vertical change (rise) between two places to the horizontal change (run). The slope-intercept form of an equation is used to express a straight line's equation, which is written as y = mx + b. The y-intercept is found where the slope of the line is m, b is b, and (0, b). For example, the slope and y-intercept of the equation y = 3x - 7 (0, 7)

To determine the equation of the line perpendicular to the line 5x + 4y = 9, travel via the point (-2, 3).

5x + 4y = 9 4y = (-5/4)x + 9/4

As a result, the slope of the supplied line is -5/4.

4/5 is the negative counterpart of -5/4.

As a result, the new line's slope will be 4/5.

y - y1 = m(x - x1), where (x1, y1) is the provided point and m is the newly discovered slope.

y - 3 = (4/5)(x + 2)

y = (4/5)x + (8/5) + 3

y = (4/5)x + 23/5

Hence the equation of the perpendicular to the line 5x + 4y = 9 line going through the point (-2, 3) is y = (4/5)x + 23/5.

As a result, the correct answer is y = (4/5)x + 23/5.

The given passage is a proof that a certain set H is a subgroup of a group X.

The given passage is a proof that a certain set H is a subgroup of a group X. It first defines H as the set of all products of elements of X and inverses of elements of X.

Then, it shows that H satisfies the three conditions necessary for it to be considered a subgroup: H contains the identity element I, it is closed under products (i.e., if h and k are in H, then hk is also in H), and it is closed under inverses (i.e., if h is in H, then h^-1 is also in H).

Finally, it concludes that since H contains all elements of X and is closed under products and inverses, it must be the smallest subgroup of X that contains X itself. Therefore, H is a subgroup of X.

Answer:

Step 1 : we will name the number of pounds of type A coffee were used is letter x then

We also do the same name the number of pounds of type B coffee were used in letter y.

Step 2: we will find the hints to find x and y

Hint 1 : We have total cost of two type A and type B is $560.5.

Price per pound of Type A : $9.95

Price per pound of Type B : $4.40

Cost = price per pound  * (multipe) number per pound .So we have an expression 1:

9.95 * x  + 4.4*y = 560.5

Hint 2: This month's blend used twice as many pounds of type B coffee as type A . That means the number of pounds of type B is double than the the number of pounds of  type A so we have a another expression 2:

y = 2*x (2)

Step 3: we have enough hints so we could find x (number of pounds of type A coffee)

We will pass the value of y = 2*x into the expression 1 so we get:

9.95 *x + 2*x*4.4 = 560.5

9.95x + 8.8x = 560.5

18.75x =560.5

x = 560.5 / 18.75

x = 29.89

The anwser is number of pounds of type A coffee is 29.89

To calculate the expected value of this lottery game, we need to find the probability of winning the game and the probability of losing the game.

Probability of winning:

There are a total of C(25, 6) possible combinations of choosing 6 numbers out of 25, where C(n, k) represents the number of combinations of choosing k items from a set of n items. The formula for combinations is:

C(n, k) = n! / (k!(n-k)!)

C(25, 6) = 25! / (6!19!) = 177100

So, there are 177,100 possible combinations. Since there's only 1 winning combination, the probability of winning is:

P(Winning) = 1 / 177,100

Probability of losing:

Since there's only 1 winning combination, the probability of losing is:

P(Losing) = 1 - P(Winning) = 1 - (1 / 177,100) = 177,099 / 177,100

Expected value:

Now, we can calculate the expected value (EV) by multiplying the probabilities of each outcome by their respective values and then summing up these products:

EV = P(Winning) * Value(Winning) + P(Losing) * Value(Losing)

EV = (1 / 177,100) * $40,000 + (177,099 / 177,100) * (-$1)

EV ≈ ($40,000 / 177,100) - ($177,099 / 177,100)

EV ≈ $0.2256 - $1

EV ≈ -$0.7744

The expected value of this lottery game is approximately -$0.7744. This means that, on average, a player would lose about 77.44 cents per game.

The answer of the given question based on the rectangular pyramid is ,  the height of the pyramid is 24 units.

Volume is the amount of space occupied by an object or a substance. It is a three-dimensional measurement that is expressed in units like cubic meters, cubic centimeters, liters, or gallons.

The volume of  rectangular pyramid is given by formula:

V = (1/3) * B * h

where V is the volume, B is the area of the rectangular base, and h is the height of the pyramid.

In this problem, we are given that the volume of the pyramid is 1824 units^3, and the length and width of the rectangular base are 12 units and 19 units, respectively. We can use this information to find the area of the rectangular base:

B = length * width = 12 * 19 = 228 units²

Substituting this value and the formula for the volume into the equation above, we get:

1824 = (1/3) * 228 * h

Multiplying both sides by 3, we get:

3 * 1824 = 228 * h

Simplifying, we get:

5472 = 228 * h

Dividing both sides by 228, we get:

h = 5472 / 228

Simplifying, we get:

h = 24

Therefore, the height of the pyramid is 24 units.

Interest that is accrued on both principal and previous interest is known as compound interest. As a result, it is often referred to as "interest over the interest". Here, the principal is increased by the interest that has already accrued, and the resulting sum serves as the new principal for the subsequent period. i.e., compound interest is equal to interest on the principal plus interest on interest already paid.

First, convert R as a percent to r as a decimal.

r = R/100

r = 5.67/100

r = 0.0567 per year,

Then, solve the equation for P:

P = A / [tex](1 + r/n)^{nt}[/tex]

P = 100,000.00 / [tex](1 + 0.0567/1)^{40}[/tex]
