What is an equation?

An equation is a statement that asserts the equality of two expressions. The expressions on either side of the equation are separated by an equals sign (=), and they must have the same value for the equation to be true.

1) 30p = 900

  p = 900/30

  p = 30

2) h/9 = 11

   h = 9 * 11

   h = 99

3) t + 32.4 = 62

   t = 62 - 32.4

   t = 31.4

4) r - 17 = 40

   r = 40 + 17

  r = 57

5)  5t = 25

      t = 25/5

      t = 5

6) 8w = 64

    w = 64/8

   w = 8

7)  9y = 81

     y = 81/9

     y = 9  

8) p + 5 = 12

   p = 12 - 5

   p = 7

9)  a + 2 = 15

    a = 15 - 2

    a = 13

10)  w + 8 = 20

      w = 20 -8

      w = 12

11)  h/6 = 4

    h = 6 * 4

    h = 24

12) g/8 = 16

    g = 16 * 8

    g = 128

13) a/7 = 3

    a = 3 * 7

    a = 21

14) y - 11 = 28

    y = 28 + 11

    y = 39

15) d - 4 = 12

    d = 12 + 4

    d = 16

16) w - 10 = 15

    w = 15 + 10

    w = 25

Hence, solutions for all the equations would be

1. p = 30

2. h = 99

3. t = 31.4

4. r = 57

5. t = 5

6. w = 8

7. y = 9

8. p = 7

9. a = 13

10. w = 12

11. h = 24

12. g = 128

13. a = 21

14. y = 39

15. d = 16

What are linear and non-linear functions?

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, Christopher has set up a lemonade stand outside his house and sells small cups and large cups of lemonade.

Small cups sold is x and the number of large cups sold is y.

Each small cup holds 10 ounces of lemonade and each large cup holds 20 ounces of lemonade and he sold 800 ounces.

Therefore,

10x + 20y = 800...(i)

He also sold twice as many small cups as large cups.

Therefore,

2y = x...(ii)

10(2y) + 20y = 800.

Mattie is twice as old as Pat. Jon is twice as old as Mattie. In 4 years the sum of their ages will be 61. How old is each person?

Answers

Answer:

Let's mark Pat's age is x. Then Mattie's age is 2x and Jon's age is 4x.

So (x + 4) + (2x + 4) + (4x + 4) = 61.

7x + 12 = 61 => 7x = 49 => x = 7.

So the answer is

Pat = 7

Mattie = 14

Jon = 28

The ages of Pat, Mattie, and Jon are as follows: 7 years, 14 years & 28 years.  

If we take Pat's age as = 'x' years,

so, Mattie's age will be = '2x' years.

and then, Jon would be = 2(2x)

                                        = '4x' years.

Now, the sum of their ages after 4 years =

 => (x+4) + (2x+4) + (4x+4) = 61

 => 7x+12 = 61

 => 7x= 61-12

 => 7x= 49

 => x= 49/7

 => x = 7

Therefore, Pat's age is  = 7 years.

              Mattie's age is = 14 years (2×7).

                  Jon's age is = 28 years (4×7).

Answers

b = $3.5 the cost of each pound of jelly beans.

a = $1, the cost of each pound of almonds

What is the elimination method?

The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients.

Here,

We let a be the almond and b be the jelly bean.

5a + 2b = $12....(1)

3a + 8b = $31....(2)

...Solving by elimination method.

5a = 12 - 2b

a = (12 - 2b)/5

Now, we put the value of a in equation(2)

3a + 8b = $31

3(12 - 2b)/5 + 8b = 31

(36 - 6b)/5 + 8b = 31

36 - 6b + 40b = 155

34b = 155 - 36

34b = 119

b = $3.5 the cost of each pound of jelly beans.

a = $1, the cost of each pound of almonds.

What is Geometric Progression?

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the geometric progression be represented as A

Now , the value of A is

A geometric progression is said to converge if the common ratio r lies between -1 < r < 1

So , If -1 < r < 1, the geometric sequence converges

a)

The geometric progression is A = 0.3 + 0.03 + 0.003 + ...

The common ratio r = second term / first term

The common ratio r = 0.03 / 0.3

The common ratio r = 0.1

So , -1 < r < 1 and the GP converges

b)

The geometric progression is A = 0.25 + 0.05 + 0.01 + ...

The common ratio r = second term / first term

The common ratio r = 0.05 / 0.25

The common ratio r = 0.2

So , -1 < r < 1 and the GP converges

c)

The geometric progression is A = 0.23 + 1.15 + 5.75 + ...

The common ratio r = second term / first term

The common ratio r = 1.15 / 0.23

The common ratio r = 5

So , r > 1 and the GP diverges

d)

The geometric progression is A = 0.75 + 0.15 + 0.03 + ...

The common ratio r = second term / first term

The common ratio r = 0.15 / 0.75

The common ratio r = 0.2

So , -1 < r < 1 and the GP converges

e)

The geometric progression is A = 0.00025 + 0.00125 + 0.00625 + ...

The common ratio r = second term / first term

The common ratio r = 0.00125 / 0.00025

The common ratio r = 5

So , r > 1 and the GP diverges

f)

The geometric progression is A = 128,750 + 25,750 + 5,150 + ...

The common ratio r = second term / first term

The common ratio r = 25,750 / 128,750

The common ratio r = 0.2

The unit rate of flavor A is; $0.2245 per ounce

The unit rate of flavor B is; $0.20 per ounce

An equation to help Ray determine how many red balloons are needed compared to the the total number of balloons used is; y = ²/₅x

How to find the unit rate?

A unit rate is also called unit ratio and it describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.

We are given that Flavor A is 20 ounces and costs $4.49. Thus;

Unit rate of flavour A = $4.49/20 = $0.2245 per ounce

For Flavor B, the equation y = 0.20x represents the cost (y) per ounce (x) in each box. Thus, the unit rate is $0.20 per ounce

Since ray is making bouquets of balloons. In each bouquet 2 out of every 5 balloons are red.

If x is the number of ounces, then the unit rate is 2/5 . Thus, the equation is; y = ²/₅x

A submarine in the middle of the ocean at a depth of 115 feet and dives to a depth of four times its initial death rate in submarines death as an integer

Answers

The integer number that represents the submarine's depth is given as follows:

-460.

What are integer numbers?

Integer number are numbers that can have either positive or negative signal, but are whole numbers, meaning that they have no decimal part.

The concepts of height and depth are given as follows:

Height is above the sea level, hence it is represented by positive integers.Depth is above the sea level, hence it is represented by negative integers.

A submarine in the middle of the ocean at a depth of 115 feet, hence the integer that represents the initial depth is given as follows:

-115.

The submarine dived to a depth that is four times the initial depth, hence the integer that represents the final depth is given as follows:

4 x -115 = -460.

(meaning that the final depth of the submarine is of 460 feet).

How do you factor with 4 parts?

Answers

When a polynomial has four or more terms, the easiest way to factor it is to use grouping.

Grouping can be understand more better with an example:

for eg:  factor x^3 + x^2 – x – 1 by using grouping. Just follow these steps:

Break up the polynomial into sets of two. You can go with (x^3 + x^2) + (–x – 1). Put the plus sign between the sets, just like when you factor trinomials. The square x2 is the GCF of the first set, and –1 is the GCF of the second set. Factoring out both of them, you get x^2(x + 1) – 1(x + 1).one can Factor again as many times as you can. The two terms you’ve created have a GCF of (x + 1). When factored out, you get (x + 1)(x^2 – 1).

However, x^2 – 1 is a difference of squares and factors again as (x+1)(x-1). This gives you a final factorization of: (x + 1)(x + 1)(x – 1), or (x + 1)2(x – 1).

What is Radius?

A circle's or a sphere's radius is the length of the line between the center and the edge.

From the center of the circle or sphere to any point on its perimeter, the radius' length is constant.

Its diameter is halved by its length.

A line segment from a circle's or sphere's center to its perimeter or boundary is known as the radius in geometry. I

Before beginning a unit of frog anatomy, a seventh grade biology teacher gives each of the 24 students in the class a pretest to assess their knowledge of frog anatomy. The teacher wants to compare the effectiveness of an instructional program in which students physically dissect frogs with the effectiveness of a different program in which students use computer software that only simulates the dissection of a frog. After completing one of the two programs, students will be given a posttest to assess their knowledge of frog anatomy. The teacher will then analyze the changes in the test scores (score on posttest minus score on pretest). a) Describe a method for assigning the 24 students to two groups of equal size that allows for a statistically valid comparison of the two instructional programs. b) Suppose the teacher decided to allow the students in the class to select which instructional program on frog anatomy (physical dissection or computer simulation) they prefer to take, and 11 students choose actual dissection and 13 students choose computer simulation. How might that self-selection process jeopardize a statistically valid comparison of the changes in the test scores (score on posttest minus score on pretest) for the two instructional programs?
