Answer:

x(x)=1/4(30+60+x)

Step-by-step explanation:

minutes spent on math homework= x

minutes spent on history homework= 30 min

minutes spent on English homework= 60 min

Total minutes spent on homework = x+30 +60

Also

x= 1/4(x+30 +60)

x= x/4 + 90/4

x-x/4= 90/4

(4x-x)/4=90/4

3x=90

x=30

Hence time spent on maths=30 min

total time spent= 30+60+30

                          = 120 min

1/4 of 120 min= 30 mins!

Answer:

A. 1/4(x + 30 + 60) = x

Step-by-step explanation:

But as you can see, 22/7 is not exactly right. In fact π is not equal to the ratio of any two numbers, which makes it an irrational number. A really good approximation, better than 1 part in 10 million, is: 355/113 = 3.1415929...

Answer: A really good approximation, better than 1 part in 10 million, is: 355/113 = 3.1415929...

Step-by-step explanation:  As you can see, 22/7 is not exactly right. In fact π is not equal to the ratio of any two numbers, which makes it an irrational number. So, therefore, the ratio that is equal to pi is 355/113 = 3.1415929...

Answer:

The two consecutive integers are -119 and -120

Step-by-step explanation:

As we know that these two integers are consecutive, that means that they will have a difference of 1. This means that we can find the two integers by adding 1 to the sum of -239 and then dividing it by two

[tex]1-239=-238\\\frac{-238}{2} =-119\\-119-1=-120[/tex]

When needing to determine two consecutive integers with a given sum, they can be represented as 'x' and 'x+1'. The equation x + (x + 1) = -239 gives us the solution of the two integers as -120 and -119.

In the given question, since we are dealing with consecutive integers, we can represent the integers as 'x' and 'x+1'. As per the information in the question, we know that the sum of these two consecutive integers is -239. Therefore, we can create the equation:

x + (x + 1) = -239

Solving this equation gives us:

2x + 1 = -239

Therefore,

2x = -240

So, x = -120

This indicates that our first integer is -120. Because we are dealing with consecutive integers, the next integer would be -120 + 1 = -119. Thus, the two consecutive integers are -120 and -119.

ANSWER

[tex]a_n=7n - 22[/tex]

EXPLANATION

The recursive rule for the sequence is

[tex]a_n=a_{n-1}+7[/tex]

In general the recursive rule is written as:

[tex]a_n=a_{n-1}+d[/tex]

This implies that, d=7

The first term of the sequence is

[tex]a_1= - 15[/tex]

The explicit rule is given by:

[tex]a_n=a_1 + d(n - 1)[/tex]

We substitute to get;

[tex]a_n= - 15 + 7(n - 1)[/tex]

[tex]a_n= - 15 + 7n - 7[/tex]

[tex]a_n=7n - 22[/tex]

Answer with explanation:

 →The equation of line which we have to write in slope intercept form is:

b. closed circles on 1 and 4 with arrows pointing outward

Step-by-step explanation:

Which of the following describes the graph of {x | x < = 1} u {x | x > = 4},

We have been given the following set;

x < = 1

This set comprises of real numbers that are less than or equal to 1;

(1, 0, -1, -2, -3, -4, .......... -∞)

On the other hand, the set x > = 4 comprises of real numbers that are greater than or equal to 4;

(4, 5, 6, 7, 8, 9, ........∞)

The symbol ∪ means a union of sets. That is the set of numbers that belong in either or both sets;

{x | x < = 1} u {x | x > = 4} is same as writing;

(1, 0, -1, -2, -3, -4, .......... -∞) ∪ (4, 5, 6, 7, 8, 9, ........∞)

Therefore, the solution set will be closed circles on 1 and 4 with arrows pointing outward

Answer:

Closed circles on 1 and 4 with arrows pointing outward ⇒ answer b

Step-by-step explanation:

* Lets study the meaning of the inequality

- If a < x < b, that means the value of x is between a and b

- If a ≤ x ≤ b, that means the value of x is from a to b

- If x < a and x > b, that means the value of x is smaller than a and

 grater than b

- If x ≤ a and x ≥ b, that means the value of x is smaller than or equal a and

 grater than or equal b

* Now lets solve the problem

∵ {x I x ≤ 1}

∴ x is smaller than or equal 1

∵ {x I x ≥ 4}

∴ x is greater than or equal 4

∵ {x I x ≤1} ∪ {x I x ≥ 4}

- The meaning of ∪ is all numbers smaller than or equal 1 and all

  the numbers greater than or equal 4

∴ {x I x ≤ 1} ∪ {x I x ≥ 4} = (-∞ , 1] ∪ [4 , ∞)

- This solution represented graphically by closed circles on 1 and

Answer:

x = 2  is the axis of symmetry

Step-by-step explanation:

y - 4x = 7 – x2?

y =  -x²+4x +7

y = - ((x²- 4x+4)-4)+7

y = - (x-2)²+11 ..... is the the parabola's equation  when : x = 2  is the axis of symmetry

The axis of symmetry for the graph of y - 4x = 7 – x² is x= 2.

The axis of symmetry is a hypothetical straight line that divides a shape into two identical sections, resulting in one component being the mirror image of the other. When folded along the axis of the symmetry, the two portions get overlaid. The straight line is also known as the line of symmetry/mirror line.

The axis of symmetry is a straight line that makes an object's shape symmetrical. The axis of symmetry produces identical reflections on all four sides. It might be horizontal, vertical, or lateral in orientation.

We have the Equation:

y - 4x = 7 – x²

Now, arranging the equation as

y =  -x²+4x +7

y = - ((x²- 4x+4)-4)+7

Now, using the algebraic Identity

(a -b)² = a² - 2ab + b²

So, the equation can be written as

y = - (x-2)²+11

This is in the parabola's equation.

Thus, the axis of symmetry is x= 2.

Answer:

A)

Step-by-step explanation:

 Since we are given the function, we can simply plug in the x as 9. So we get 50(0.952)9. Solving this, we get 450(.952) and this is about 428. SO our answer is a) about 428 feral cats.

There will be 428 feral cats in 9 years.

We can substitute the given number in the function to find the required value here, years are represented by x. Therefore, we must substitute the value of x = 9 in the function to find the population of feral cats in 9 years.

The function is given as:

f(x) = 50(0.952)x.

We have to find the number of feral cats in 9 years. Therefore, the value of x is 9.

Now, we can substitute the value of x in the function. This can be done as follows:

f(x) = 50(0.952)x

f(9) = 50(0.952)*9

f(9) = 50(8.568)

f(9) = 428.4

f(9) ≈ 428

We have found the number of feral cats in 9 years. The number of feral cats that will be alive after 9 years is found to be 428.

Therefore, we have found that there will be 428 feral cats in 9 years. The correct answer is option A.

The surface area of the pyramid is 160ft^2

To find the surface area of a pyramid, we need to calculate the sum of the areas of all its faces. A pyramid has 4 triangular faces and 1 square base. The formula for the surface area of a pyramid is: Surface Area = Base Area + (0.5 × Perimeter of Base × Slant Height). In this case, the base side of the pyramid is 8ft and the slant height is 6ft.

First, we calculate the perimeter of the square base, which is 4 times the length of the base side: Perimeter = 4 × 8ft = 32ft.

The base area of the pyramid is found by squaring the length of one side of the base: Base Area = (8ft)^2 = 64ft^2.

Now we can substitute the values into the formula: Surface Area = 64ft^2 + (0.5 × 32ft × 6ft) = 64ft^2 + 96ft^2 = 160ft^2.

The surface area of a pyramid with an 8 ft side length and a 10 ft slant height is 224 square ft. Hence, option A is correct.

To find the surface area of a pyramid with a square base, we need to calculate both the base area and the lateral surface area.

The side length of the square base is 8 ft, so the base area is:

The slant height of the pyramid is 10 ft, and the side length of the base is 8 ft. Each triangular face of the pyramid has a height (slant height) and base equal to the side of the square base. The area of one triangular face is:

Since a square-based pyramid has 4 triangular faces, the total lateral surface area is:

Adding the base area and the lateral surface area gives the total surface area:

Therefore, the total surface area of the pyramid is (Option A) 224 square ft.
