estimate the difference of 1 1/5 - 9/10
estimate the difference of 1 1/5 - 9/10
we have
1 1/5=1+1/5=6/5
6/5=12/10
so
12/10-9/10=3/10=0.3
answer is 0.3
estimete
1 1/5 is about 1
9/10=0.9
so
1-0.9=0.10
the estimate is 0.10
steps
Rounded 1 1/5------> 1
we know that
9/10=0.9
so
substitute
1-0.9=0.10

Create your own quadratic equation whilst explaining how to use the quadratic formula to solve it. Be specific, using a, b, and c of your equation and give solutions to theequation you chose.
Let the quadratic equation is
[tex]x^2-8x+16=0[/tex]Here, a is the coefficient of x^2, b is the coefficient of x and c is the constant.
For the equation we have a = 1, b = -8 and c = 16.
We know that the quadratic formula is given by:
[tex]x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}[/tex]So, the solution of the quadratic equation is:
[tex]\begin{gathered} x=\frac{-(-8)\pm\sqrt[]{(-8)^2-4(1)(16)}}{2(1)} \\ x=\frac{8\pm\sqrt[]{64-64}}{2} \\ x=\frac{8\pm\sqrt[]{0}}{2} \\ x=\frac{8}{2} \\ x=4 \end{gathered}[/tex]Thus, there are two real and equal solutions for the given quadratic equation that is x = 4 and x = 4.
Evaluate x^3 - 6y + 2 for x = 4 and y= 6.
The given expression is x^3 - 6y + 2
We are gven x = 4 and y = 6
Substituting the given values into the expression, it becomes
4^3 - 6*6 + 2
= 12 - 36 + 2
= - 22
a model of a skyscraper is made so that 1 inch represents 75 feet what is the height of the actual building if the height of the model is 20 1/4 inches
Given the proportional relationship:
1 in = 75 feet
To get feet, of 20 1/4th inches, we have to multiply the inches by 75:
[tex]\begin{gathered} 20\frac{1}{4}\times75 \\ =\frac{81}{4}\times75 \\ =\frac{6075}{4} \\ =1518\frac{3}{4}\text{ fe}et \end{gathered}[/tex]Note: we converted 20 1/4th to improper fraction, then did the mulitplication.

a) y =2^x
b) Exponential
c)
a) According to that graph, we have point (1,2) and (2,4) since that exponential function is
[tex]\begin{gathered} y=a(b)^x \\ 1=a(b)^0\rightarrow a\text{ =1} \\ 4=ab^2\text{ }\rightarrow4\text{ =}b^2\rightarrow\text{ }b=2 \\ y=2^x \end{gathered}[/tex]Since the function is increasing, due to its direction, we can write y =2^x
b)The type of function is exponential, since x= 0, y = 1, and due to its shape.
3) As we can see the shape of the graph is curve,
chords AB and CD intersect as shown nelow find the length of CD
We are asked to determine the length of CD, to do that we will use the following relationship:
[tex]\begin{gathered} CD=21+x+1 \\ CD=22+x \end{gathered}[/tex]Therefore, we need to determine the value of "x". To do that we will use the intersecting chords theorem, that is:
[tex](21)(x+1)=(9)(3x-9)[/tex]Now we solve for "x" first by applying the distributive law:
[tex]21x+21=27x-81[/tex]Now we will subtract 21 to both sides:
[tex]\begin{gathered} 21x=27x-81-21 \\ 21x=27x-102 \end{gathered}[/tex]Now we will subtract 27x to both sides:
[tex]\begin{gathered} 21x-27x=-102 \\ -6x=-102 \end{gathered}[/tex]Dividing both sides by -6:
[tex]x=-\frac{102}{-6}=17[/tex]Now we replace the value of "x" in the expression for segment CD:
[tex]\begin{gathered} CD=22+17 \\ CD=39 \end{gathered}[/tex]Therefore, the length of CD is 39.

Let "x" represent the width of the rectangular steel, then the length, which is 2meters less than triple the width, can be expressed as "3x-2".
The perimeter of the rectangular piece is 60meters.
The formula for the perimeter is the following:
[tex]P=2w+2l[/tex]Replace the formula with the expressions for the width and length and the given perimeter of the piece of steel:
w=x
l=3x-2
P=60
[tex]60=2x+2(3x-2)[/tex]From this expression, you can determine the value of x.
-First, distribute the multiplication on the parentheses term
[tex]\begin{gathered} 60=2x+2\cdot3x-2\cdot2 \\ 60=2x+6x-4 \end{gathered}[/tex]-Second, simplify the like terms and pass "-4" to the left side of the expression by applying the opposite operation "+4" to both sides of it
[tex]\begin{gathered} 60=8x-4 \\ 60+4=8x-4+4 \\ 64=8x \end{gathered}[/tex]-Third, divide both sides by 8 to determine the value of x
[tex]\begin{gathered} \frac{64}{8}=\frac{8x}{8} \\ 8=x \end{gathered}[/tex]The value of x is 8m, which means that the width of the piece of steel is 8m
To determine the length you just have to replace the expression by x=8
[tex]\begin{gathered} l=3x-2 \\ l=3\cdot8-2 \\ l=24-2 \\ l=22 \end{gathered}[/tex]The length is 22m
f(x) = (x-1.5)^2 find the vertex
The given function is
[tex]f(x)=(x-1.5)^2[/tex]It is important to know that the function is in vertex form
[tex]f(x)=a(x-h)^2+k[/tex]Where h and k are the coordinates of the vertex.
Having said that, we can deduct that the vertex of the given function is (1.5, 0) because those are the values for h and k.
Hence, the answer is V(1.5, 0).4. During a long weekend, Devon paid a total of x dollars for a rental car so he could visit his family. He rented the care for 4 days at a rate of $36 per day. There was an additional charge of $0.20 per mile after the first 200 miles.
a. Write an expression to represent the amount Devon paid for additional mileage.
b. Write an expression to represent the number of miles over 200 miles that Devon drove.
c. How many miles overall did Devon drive overall if he paid $174 for the car rental? Show work.
Answer:
A)
c = 0.20m + 144
Where c is total cost and m is miles driven.
B)
c = (200 + 0.20m) + 144
C)
174 = 0.20m + 36x4
174 = 0.20m + 144
30 = 0.20m
30/0.20 = m
m = 150+200
m = 350miles

Jay had 60 tickets he could turn in at the end of the year for extra-credit points he had earned during the year. Some tickets were worth two points and others were worth five points. If he was entitled to a total of 231 extra-credit points, how many two-point tickets did he have?
Answer:
23 2-points + 37 5-points = 231
Step-by-step explanation:
Answer:
53 two-point tickets.
Step-by-step explanation:
This is a system of equations:
x + y = 60
2x + 5y = 231
Then..
-2x - 2y = -120
2x + 5y = 231
Then...
3y = 111
y=7
All you need to do now is plug it in:
x + 7 = 60
60-7 = x
x = 53

Solve the inequality and draw the solution |r|-3>2
We want to solve the following inequality
[tex]|r|\text{ -3 >2}[/tex]To solve this inequality, we first add 3 on both sides, so we get
[tex]|r|>2+3=5[/tex]So we have the inequality
[tex]|r|>5[/tex]Recall that the absolute value represents the distance from a number to 0. So this means that the number r is greater than 5 or it is less than -5. So we have the following two inequalities
[tex]r>5[/tex][tex]r<\text{ -5}[/tex]This could be drawn on the number line as follows. Greater than (>) means that the number 5 is on the left, and the less than (<) means that the number -5 is on the right side. So we get the following

One positive integer is 2 less than twice another. The sum of their squares is 745.
The numbers are 13 and 24
What is Integers?
The negative numbers are the additive inverses of the corresponding positive numbers.[2] In the language of mathematics, the set of integers is frequently denoted by the boldface Z or blackboard bold displaystyle mathbb Z mathbb Z.[3][4][5] An integer is the number zero (0), a positive natural number (1, 2, 3, etc.), or a negative integer with a minus sign
y=first number
x=2y-2 (second number)
y^2+(2y-2)^2=745
y^2+4y^2-8y+4=745
5y^2-8y+4-745=0
5y^2-8y-741=0
Now, from the equation we can solve
5y^2 -65y +57y - 741 = 0
5y(y - 13) + 57(y - 13) = 0
(5y + 57)(y - 13)= 0
now, since the Integers are positive so the value obtained from (5y + 57) = 0 can't hold true.
So, y-13 = 0
y = 13
The first number is : 13
The second number is :
x = 2(13) - 2
x = 26 - 2
x = 24
The second number is : 24
Hence, the numbers are 13 and 24
