For the past 4 years, Jesse has grown 3 inches each year. He is now 15 years old and is 5 feet 6 inches tall. He predicts that when he is 20 years old, he will be 6 feet 9 inches tall. What would you tell Jesse about his prediction?
Answers
He estimates that he will stand 6 feet 9 inches tall when he is 20 years old. His prediction is correct.
How to check Jesse's prediction?Given: Growth per year = 3 inches
Height at 15 yrs of age = 5'6''
Height at 20 yrs of age = 6'9''(predicted)
We know that Jesse grows 3 inches every year.
In 5 years(15yrs - 20yrs) his growth = 5 × 3 = 15 inches.
At 15 years(present) height = 5'6''
At 20 years (future) height = 5'6'' + 15'' = 6'9'' (since, 1ft = 12 inches)
Thus, Jesse's prediction is correct

Δ A B C has vertices A(-3,3), B(2,5) , and C(4,-3) . What are the coordinates of the centroid of ΔA B C ? Explain the process you used to reach your conclusion.
Answers
The coordinates of the centroid of Δ ABC is y = -1/3x + 2.
What is meant by the slope of the line?
The slope of the line is the rise-to-run ratio or the rise divided by the run. It expresses the slope of a line in the coordinate plane. Finding the slope of a line is similar to determining the slope between two points.
The midpoint D of AC is (-3+4/2, 3-3/2) or (1/2, 0).
Note that DB is a line that connects the vertex B and D, the midpoint of AC.
The slope of the line DB is ((5-0)/(2-1/2)) or 10/3.
The equation of DB is
y - 5 = 10/3 (x - 2)
simplifying the above equation, we get
y - 5 = 10x/3 - 20/3
y - 5 + 5 = 10x/3 - 20/3 + 5
y = 10x/3 - 5/3
Use the same method to find the equation of the line between point A and the midpoint of BC.
Therefore, the coordinates of the centroid of Δ ABC is y = -1/3x + 2.

Write the component form of →PQ .
Answers
The vector PQ is given by the addition of the components of the two vectors i.e. →PQ = →Q + →P
Vector is a quantity having magnitude as well as direction and is used to denote the mathematical and geometrical direction of the given quantity.
For example : Velocity, Displacement etc.
Let us first assume that,
P(x,y,z) and Q(u,v,w)
Now, we need to find the vector PQ
→PQ = →Q + →P
= (ui + vj + wk ) + (xi + yj + zk)
= (ui + xi ) +(vj + yj) + (wk +zk)
= (u+x) i + (v + y) j + (w + z)k
= →PQ
For example : Let P(1,2,1) and Q ( -1, -2,4)
Then, →PQ = →Q + →P
= (1i + 2j + 1k ) + (-1i + (-2)j + 4k)
= (1-1) i + (2 -2) j + (1 + 4)k
= oi+0j +5j
= 5j
Hence, the vector PQ is given by the addition of the components of the two vectors.

The correct answer is A. 13.
We have been given equation. Now, to find the value of x, we will take square root. So, solving the mathematical expression now -
x = √169
Taking square root to find the value of x
x = 13
Since the number is positive. the square root of the number will also be positive.
Hence, the solution to equation is A. 13.
Further to cross check, we can also square the resultant number.

The product of the smallest and largest integer is 672
What is the product of the smallest and largest integer?Represent the smallest even integer with x.
So, the other even integers are x + 2 and x + 4
The sum is represented as
x + x + 2 + x + 4 = 18 + 5/2x
Evaluate the like terms
3x + 6 = 18 + 5/2x
Evaluate the like terms
1/2x = 12
Multiply by 2
x = 24
The largest integer is x + 4
So, we have
x + 4 = 24 + 4
x + 4 = 28
The product of the smallest and largest integer is
Product = 24 * 28

A brick path is being installed around a circular pond. The pond has a circumference of 68 feet. The outer edge of the path is going to be 4 feet from the pond all the way around. What is the approximate circumference of the path? Round to the nearest hundredth.
Answers
The approximate circumference of the path Round to the nearest hundredth is 93.12 feet.
What is circumference of circle?A circle's outside boundary is called the circumference and can be measured, or calculated, by using
Circumference = 2πr
where r is the radius of circle.
Now it is given that,
circumference of pond = 68 feet
⇒ 2πr = 68
⇒ r = 34/π
⇒ r = 10.82 feet
Now it is also given that, The outer edge of the path is going to be 4 feet from the pond all the way around
⇒ Radius of path, R = r + 4
⇒ Radius of path, R = 10.82 + 4
⇒ R = 14.828
So,circumference of the path = 2πR
⇒ circumference of the path = 2π*14.828 = 93.119 feet
⇒ circumference of the path Round to the nearest hundredth = 93.12 feet
Thus, the approximate circumference of the path Round to the nearest hundredth is 93.12 feet.

How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2

In mathematics, an inequality is a relation which makes a non-equal comparison between the two numbers or other mathematical expressions. Inequalities have no solution are X>X, -4+X>-2+X.
What do you mean by inequality?An inequality compares two values, showing if one is less than, greater than, or simply not equal to the another value.
The a ≠ b says that a is not equal to bThe a < b says that a is less than bThe a > b says that a is greater than b (those two are known as strict inequality)The a ≤ b means that a is less than or equal to bThe a ≥ b means that a is greater than or equal to b.Inequalities are governed by following properties. All of these properties also hold if all of non-strict inequalities (≤ and ≥) are replaced by their corresponding strict inequalities (< and >) and — in case of applying a function — monotonic functions are limited to the strictly monotonic functions.

Suppose we draw a single card from a deck of 52 fair playing cards. what is the probability of drawing an ace or a two?
Answers
The probability of getting an Ace is 1/13.
Probability of an event = number of favorable outcomes for the event/number of all possible products.
First, let's calculate the number of all possible outcomes. Randomly picking the cards could result in each of the 52 being selected. So, there are 52 possible outcomes.
But if you want an Ace in your desired event, you have four options—ace of Spades, Ace of Clubs, Ace of Hearts, and Ace of Diamonds. Therefore, the number of favorable outcomes for Aces = 4.
Therefore,
The probability of getting an Ace with a deck of 52 cards = 4/52 = 1/13.

A student has some 1 bills and 5 bills in his wallet. He has a total of 15 bills that are worth 47 . How many of each type of bill does he have?
Answers
If a student has some 1 bills and 5 bills in his wallet and he has a total of 15 bills that are worth 47, then the number of 1 bills he has is equal to 7 and the number of 5 bills he has is equal to 8.
The number of bills of each type can be calculated by forming a system of equations.
Consider x to be the number of 1 bills and y to be the number of 5 bills.
The first equation can be given as,
x + y = 15
The second equation can be given as,
x + 5y = 47
The two equations can be solved by using the substitution method:
By rearranging the first equation the value of x can be calculated to be,
x + y = 15
x = 15 - y
Putting this value of x in the second equation,
x + 5y = 47
15 - y + 5y = 47
4y = 47 - 15
4y = 32
y = 32 ÷ 4
y = 8
The value of x can be determined by putting y = 8 in the first equation,
x + y = 15
x + 8 = 15
x = 15 - 8
x = 7
Hence, the number of 1 bills and 5 bills are equal to 7 and 8 respectively.
