Richard started his walk at the ice cream shop. He reached the library and continued to the park. If Richard walks for a total of 20/8 miles, how much farther did he walk beyond the park?
Answer:
He has walked almost 12 miles beyond the park.
Step-by-step explanation:
Richard walked for a total of 20/8 miles. He started the walk from ice cream shop and then reached the library. The distance from library to the ice cream shop is 8 miles. The total distance that he travelled from the library to park is 12 miles.

Square FGNM and its diagonals are shown below. Which pairs of line segments are parallel? Select all that apply.
Answer:
The parallel sides are:
- FG and MN
- GN and FM
Step-by-step explanation:
The question is incomplete, as the image of the square is not attached.
However, I will answer this question using a general rule.
When a square is named ABCD, it means that AB and DC are parallel sides & BC and AD are also parallel
Using this logic, the parallel sides of FGNM are:
- FG and MN
- GN and FM
The diagonals are:
FN and GM

Ray wants to buy a hat that costs $10 and some shirts that cost $12 each. The sales tax rate is 6.5%. The expression 0.065(10+12s) can be used to determine the amount of sales tax that Ray will pay on his entire purchase. Expand the expression
Answer: 0.65 + 0.78s
Step-by-step explanation:
From the question, we are informed that Ray wants to buy a hat that costs $10 and some shirts that cost $12 each and that the sales tax rate is 6.5%.
We are further told that the expression 0.065(10+12s) can be used to calculate the amount of sales tax that Ray will pay on his entire purchase.
Therefore, expanding the expression will give:
= 0.065(10+12s)
= (0.065 × 10) + (0.065 × 12s)
= 0.65 + 0.78s
Order the following set of rational numbers from least to greatest: -8, -19, 0, 1/2, 1/4
Answer:
[tex]-19,-8,0,\frac{1}{4}, \frac{1}{2}[/tex]
Step-by-step explanation:
Skills required: Ordering a set of numbers
1) [tex]-8,-19,0,\frac{1}{4}, \frac{1}{2}[/tex] are the numbers we are given. There are 2 important things to think about when ordering this set.
Negative numbers (the numbers with a "-" sign in front of it) are always less than 0. Negative numbers are: -1, -5, -67, -990Positive numbers (the numbers without a "-" sign in front of them) are always greater than 0. Positive numbers are: 1, 3, 45, 672) Based on this, we can split the 5 numbers into 3 groups:
The negative group: -8,-19The special group: 0The positive group: [tex]\frac{1}{2}, \frac{1}{4}[/tex]3) Starting with the negative group, we can easily find which number is greater.
-1 is greater than -2.
-23 is greater than -35.
Based on this: -8 is greater than -19. That means when ordering our numbers, -8 is the first number, and -19 is the second number
4) 0 is the 3rd number, since it is less than positive numbers and greater than negative numbers
5) Now onto the positive numbers, which is also easily solvable.
When you have two fractions, there are different ways to find out which fraction is greater than the other. I will show you 2 different ways here.
Do division. [tex]\frac{1}{4}[/tex] is 1 ÷ 4 and [tex]\frac{1}{2}[/tex] is 1 ÷ 2. So, generally, given a fraction [tex]\frac{x}{y}[/tex], you would do x ÷ y to find the decimal form. If you know how to compare decimals, this is a good way. 1 ÷ 4 is 0.25 and 1 ÷ 2 is 0.5, and 0.5 is greater than 0.25, making [tex]\frac{1}{2}[/tex] greater than [tex]\frac{1}{4}[/tex] Compare denominators. So, these two fractions have the same numerator of 1. To find out which is greater, we can look at the denominators. If 2 fractions have the same numerator, the one with a lower denominator is greater, when looking at positive numbers. 2 is less than 4, so [tex]\frac{1}{2}[/tex] is greater than [tex]\frac{1}{4}[/tex]This means that [tex]\frac{1}{4}[/tex] is the 4th number, and [tex]\frac{1}{2}[/tex] is the 5th term.
Our ordered pair would then be: [tex]-19,-8,0,\frac{1}{4}, \frac{1}{2}[/tex]

A taxi charges a $2 flat fee plus $2.35 per mile. If Caleb can spend no more than $47, write and solve an inequality to represent the number of miles m he can ride in the taxi.
Select the correct inequality to represent this situation.
2.35 + 2m < 47
2 + 2.35m ≤ 47
2.35 + 2m ≤ 47
2 + 2.35m < 47
Answer:
2+2.35<47
Step-by-step explanation:
because the taxi charge $2 + $2.35 per mile and < means you spend less than $47.

Given: y= 2x + 1 and - 4x + y = 9,
solve the system by substitution
Answer:
x=-4 y=-7
Step-by-step explanation:
-4x+y=9 get y alone
add 4x both sides
y=4x+9
insert into y=2x+1
2x+1=4x+9
subtract 1 both sides
2x=4x+8
subtract 4x both sides
-2x=8
divide by -2
x=-4
y=2x+1
y=2(-4)+1
y=-8+1
y=-7
check
-4(-4)+(-7)=9
-16+(-7)=9
9=9
x=-4
y=-7

History of algebra
Algebra can essentially be considered as doing computations similar to those of arithmetic but with non-numerical mathematical objects. However, until the 19th century, algebra consisted essentially of the theory of equations. For example, the fundamental theorem of algebra belongs to the theory of equations and is not, nowadays, considered as belonging to algebra (in fact, every proof must use the completeness of the real numbers, which is not an algebraic property).
This article describes the history of the theory of equations, called here "algebra", from the origins to the emergence of algebra as a separate area of mathematics.

CDE is reflected over the Y- Axis
Answer:
The answer to this question is A
The new coordinates will be C( 3 ,0), D( 7,1) , E(2,4) , Option A is the correct answer.
What is the meaning of Reflection ?When a object or a figure is reflected , it means an mirror image if the object is being created , the shape and size of the object remains same , Only the coordinates change on the basis of the axis used for Reflection.
The figure is given in the question.
The coordinates of the figure is
C( -3 ,0)
D( -7,1)
E(-2,4)
When reflection is done along any axis , the coordinates of the other axis change sign.
so in this case ( x,y ) -----> ( -x,y)
The new coordinates will be
C( 3 ,0)
D( 7,1)
E(2,4)
Therefore Option A is the correct answer.

Step-by-step explanation:
Pi x radius² = area of a circle
Sixteen inches is the diameter and since the radius is half the diameter, this must mean the diameter is eight inches.
Therefore, if we substitute this into the equation, pi x eight² is the area.
This could be written as sixty four pi or 201.06192983 in²
This means the closest answer is C
Answer:
C
Step-by-step explanation:
Area= π(r squared)
Area= π(8 squared)
Area= 200.96 in squared
