x>=45 is the req. inequality

The inequality equation for the number of tickets to be sold is x ≥ 45

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the number of tickets to be sold be x

Let the total amount of money to be saved be = $ 800

The amount of money already saved = $ 350

So , the remaining amount of money = $ 800 - $ 350 = $ 450

The cost of each ticket = $ 10

So , the cost of x tickets = 10x

Now , the number of tickets to be sold to raise $ 450 is given by

10x ≥ 450   be equation (1)

On simplifying the equation , we get

Divide by 10 on both sides of the equation , we get

x ≥ 45

Therefore , the number of tickets to be sold is 45

Hence , the inequality is x ≥ 45

A committee with 4 democrats and 2 republicans formed from a group of 7 democrats and 5 republicans can be created in a total of 350 ways. Therefore, the option C holds true.

The calculation of the same has been shown as below,

A group has 7 Democrats and 5 Republicans.

Committee with 4 Democrats and 2 Republicans = 7C4 x 5C2

7C4 x 5C2 = 7! / (4! 3!) x 5! / (2! 3!)

7C4 x 5C2 =(7×6×5 / 3×2×1) x (5×4 / 2×1)

7C4 x 5C2 = 35 × 10

7C4 x 5C2 = 350

The amount of worth of machine Larry needs to sell to recieve 15,000 dollars is 125, 000 dollars.

Larry  thinks the big money is in rowing machines. If Larry switches jobs,

he will earn a 12% commission on all the machines he sells. For Larry to

receive $15,000 in commissions, the worth of dollars of machines he must

sell can be computed as follows:

Therefore,

let

x = amount he will earn

Hence,

15, 000 = 12% of x

15,000 = 12 / 100 × x

15000 = 12x / 100

cross multiply

1500000 = 12x

divide both sides by 12

x = 1,500,000 / 12

x = 125,000

Therefore, he needs to sell $125, 000 worth of machine.

To find the percent that 1.5 is of 7.5, we need to divide 1.5 by 7.5 and multiply the result by 100% to convert it to a percentage:

1.5 / 7.5 = 0.2

0.2 * 100% = 20%

Therefore, 1.5 is 20% of 7.5.

To find the percent that 5ft is of 37.5ft, we need to divide 5 by 37.5 and multiply the result by 100% to convert it to a percentage:

5ft / 37.5ft = 0.1333

0.1333 * 100% = 13.33%

Therefore, 5ft is 13.33% of 37.5ft.

The probability that exactly two of thirteen fireworks are blue ones out of total 4 selections is 63/143.

The stated data;

You want 2 of the 7 items she selects to be blue, leaving 2 to be red.

Selecting 2 blue out of 7 blues is ⁷C₂ = 7!/(5!.2!)  =  21

Selecting 2 red out of 6 red = ⁶C₂ = 6!/(4!2!) = 15

Selecting total of 4 out of 13 ; ¹³C₄ = 13! / (9!.4!) = 715

Thus, probability that exactly two of them are blue ones;

P(2 blue) = 21 x 15 / 715

P(2 blue) = 63/143

Thus, probability that exactly two of them are blue ones out of total 4 selections is 63/143.

In the given question,

The 2 digit number which become 5 by 6th of itself when it digit are revered.

The difference in the digit of the number being 1, then we have to find the two digit number.

Let the two digit number = 10y+x

When we reversed the number then the number is 10x+y

As given that;

10y+x = 5/6(10x+y)

Multiply by 6 on both side, we get

60y+6x = 50x+5y

Subtract 5y on both side, we get

55y+6x = 50x

Subtract 50x on both side, we get

55y-44x = 0

Divide by 11 on both side, we get

5y-4x = 0

4x-5y = 0......................(1)

It is given that the difference between the number is 1.

x-y = 1..................(2)

Multiply by 4 in equation 2

4x-4y = 4.........................(3)

Now subtract equation 3 and 1, we get

y = 4

Now putting the value of y in equation 2

x-4 = 1

Add 4 on both side, we get

x = 5

Since the number is 10y+x. So

10y+x = 10(4)+5

The equilibrium price is; $12

The quantity for the two equations is; 400

The equilibrium price formula is based on the demand and supply quantities; you will set quantity demanded (Qd) equal to quantity supplied.

The equilibrium price definition above is one that tells us that there is a price point that meets the needs of both supply and demand. In order to understand when those needs are met, we need to know how to find equilibrium price.

We are given;

Quantity supplied; S(p) = -200 + 50p

Quantity demanded; D(p) = 1060 - 55p

Thus, equilibrium price is p when;

S(p) = D(p)

-200 + 50p = 1060 - 55p

1060 + 200 = 55p + 50p

1260 = 105p

p = 1260/105

253 is not divisible by 3 or 9 since the sum of digits is not divisible by 3 or 9. It is not divisible by 7 (since 25 - 3*2 = 19 is not divisible by 7) but divisible by 11, since the sum of digits in odd places is same as the digit in the even place (recall divisibility by 11):

Answer: This means that the range of values of k is k ∈ [-1/3, 1/3].

Step-by-step explanation: The quadratic equation (x+2)² +3k-1=0 can be written as (x+2)² = 1-3k. For the equation to have two real and distinct roots, the expression under the square root must be nonnegative. Therefore, we have the inequality 1-3k ≥ 0. Solving this inequality gives us -1/3 ≤ k ≤ 1/3. This means that the range of values of k is k ∈ [-1/3, 1/3].

The linear equation on the table is the one in option D.

y = 25*x + 45

A general linear function is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we know two points on the line, (x₁, y₁) and (x₂, y₂), the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

Using the first two points, (0, 45) and (1, 70) we can get the slope:

a = (70 - 45)/(1 - 0) = 25

And because of the point (0, 45) we know that the y-intercept is b = 45, then the linear equation is:

y = 25*x + 45

So the correct option is D.
