Answer:5

Step-by-step explanation:

The total number of possible solutions for both the inequalities to be true at the same time are 3.

Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.

Given in the question is the solution of two inequalities as a function of x.

Since, both the inequalities must be true at the same time, this means that only those solutions will be taken into consideration which are common to both. In order to do so, we have to find the intersection of the sets representing their solutions. Now,

Solution set for inequality 1 → S[1] ∈ [-3, 2)

Solution set for inequality 2 → S[2] ∈ (-1, 4]

The set representing the solution for the existence of both the inequalities at the same time is -

S = S[1] ∩ S[2] = [-3, 2) ∩ (-1, 4] = [0, 1, 2]

n(S) = 3

Therefore, the total number of possible solutions for both the inequalities to be true at the same time are 3.

According to the given value;

side of square floor 5.6

a = 7x³y⁰

Side of suare tiles s=x²y

Area of square floor is

A = a

A = (7x³y6) ²

A = 49x1012

Area of square tiles,

A₁ = s

A₁ = (x²y)²

A=x⁴y²

Now the number of tiles required,

n=\frac{A}{A_t}

Substitute the data,

n =49x¹ y 12

Consider two points P([tex]x_{1} ,y_{1}[/tex]) and Q([tex]x_{2},y_{2}[/tex]).Finding the coordinates of the point R that divides PQ in the ratio m: n is necessary because [tex]\frac{PR}{RQ}[/tex] = [tex]\frac{m}{n}[/tex].

The value of the unknown variable x in the equation x² + 5² = 13² is 12.

The use of numbers and words in the same mathematical equation is considered as an algebraic expression.

We can calculate the square of a number by multiplying the number by itself.

Therefore, the square of 5 is equal to 5 multiplied by 5 which is equal to 25.

While the square of 13 is equal to 13 multiplied by 13 which is equal to 169.

So to find the value of x, we can rearrange the given equation as:

x² = 13² - 5 ²

x² = 169 - 25

x² = 144

As x² is equal to 144, we can calculate the value of x by taking the square root of the value of 144.

Therefore,

x= √144

x= 12

Hence, the value of the unknown variable x in this equation is 12.

The sum of the arithmetic series 4+9+14+19+24+ . . . . . . . +99 is S(20) = 1030

The given series:

4+9+14+19+24+ . . . . . . . +99

We can conclude:

a(1) = 4

a(n) = 99

d = 9 - 4 = 5

Find n using the formula of nth term.

a(n) = a(1) + (n-1) . d

99 = 4 + (n -1). 5

99 = 5n - 1

5n = 100

n = 20

Find the sum for the n terms using the sum formula of an arithmetic series:

S(n) = n/2 (a(1) + a(n))

Substitute n = 20, a(1) = 4, and a(20) = 99

S(20) = 20/2 . (4 + 99)

Comparing the unit price of each bag of fries, the large bag of fries, which costs $0.014825 per gram, has the lower cost per gram than the other bag.

Unit price is defined as the price or the cost per unit of the item. The importance of the unit price is that it allows the buyer to understand how the total price has been calculated. Unit price can be solved by dividing the total cost to the total amount of the item.

unit price = total cost/total amount

Solving for the unit price of each bag of fries:

small bag : unit price = $1.39/80 grams = $0.017375/gram

large bag : unit price = $1.69/114 grams = $0.014825/gram

$0.014825 < $0.017375
