What is the mean of the numbers given below? 1, 5, 7, 9, 11, 16, 18, 20, 30, 35 Report your answer in decimal form. Enter
Answer:
15.2
Step-by-step explanation:
1) First, add all of the numbers together. 1+5+7+9+11+16+18+20+30+35=152.
2) Then, divide this by the amount of numbers. There are 10, so it is 152÷10=15.2
3) The answer is 15.2
Rewrite each expression by combining like terms.

Answer:
ill try what's the problem???
Step-by-step explanation:
Solve the following story problem.
The perimeter of a rectangle is 60 inches. The length is four times the
width.
What are the length and width of the rectangle?
Define your variables.
X =
Equation 1
y =
Equation 2
What is the length?
what is the width?
Answer:
The perimeter of a rectangle is equal to 2L + 2W, where L = the length of the rectangle and W = the width of the rectangle. So, one equation is
2L + 2W = 60
From the info given in the problem, we also know that L = 4W. Therefore, we can use the Substitution Method to re-write the first equation as:
4W + 2W = 60
You should be able to solve this equation for W. Once you find W, you can then calculate L.

write an algebraic expression for the verbal expression
x more than 7
Answer:
x+7
Step-by-step explanation:
idek kinda thought that was obvious but who know I could be wrong
The algebraic expression for the verbal expression x more than 7 will be x + 7.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The algebraic expression for the verbal expression x more than 7 will be
The numbers will be x and 7. And the sum of the numbers x and 7 will be given as,

Eight angles of a nonagon measure 1389, 154º. 145°, 132°, 148°, 143,
147°and 150°. What is the measure of the ninth angle?
Answer:
103°
Step-by-step explanation:
The total angle in a nonagon is 1260. To get the missing angle, we add up all the given angle together and subtract it from 1260.
138 + 154º + 145° + 132° + 148° + 143 + 147 + 150 = 1157
1260 - 1157 = 103
Therefore, the missing angle is 103°
Find the length of the third side. If necessary, write in simplest radical
form.
8
17
Answer:
9
Step-by-step explanation:
so we know that its a right triangle and 8 and [tex]\sqrt{17}[/tex] are not the hypotenuse.
the equation for this is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex] with c being the hypotenuse.
[tex]8^{2}[/tex]+[tex]\sqrt{17} ^{2}[/tex]=[tex]c^{2}[/tex]
64+17=[tex]c^{2}[/tex]
81=c
[tex]\sqrt{81}[/tex]=c
9=c
Answer:
Step-by-step explanation:
To make the use of Pythagoras's theorem clear
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]
where C is they hypotenuse or Hyp
A is one side often called the Adjacent side
B is the other side often called the Opposite side
when A = 8
and B = [tex]\sqrt{17}[/tex]
then
[tex]C^{2}[/tex] = [tex]8^{2}[/tex] + [tex]\sqrt{17} ^{2}[/tex]
[tex]C^{2}[/tex] = 64 + 17
[tex]C^{2}[/tex] = 81
C = [tex]\sqrt{81}[/tex]
C = 9

f(x)=2x^2-5x-20
find f(-9)
Answer:
The output when x = -9 is f(x) = 187.
Step-by-step explanation:
We are given a function and asked to find the output of that function.
The input of a function refers to a value that is substituted into the function in order to simplify it to a final value.The output of a function is the value that is achieved when the input is substituted into the equation and the function is evaluated.Our standard function is in the form of a quadratic equation.
[tex]ax^2+bx+c=0[/tex]
Let's check for a change in the presentation of the first value in the equation.
[tex]\bold{f(x)} = 2x^2 - 5x - 20\\\\\bold{f(-9)}[/tex]
We see that x becomes -9. We also know that from conventional algebra, we need to make this change throughout the entire equation. Therefore, since we changed the x in f(x), we need to change it in 2x² - 5x - 20 as well.
[tex]f(-9) = 2(-9)^2 - 5(-9) - 20[/tex]
Now, it's time to simplify this function. Let's first simplify the first term of the function: [tex]2(-9)^2[/tex].
Let's follow PEMDAS in order to simplify the term.
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
When using this acronym, make sure that all operations are performed left to right.
We see that -9 is raised to the power of 2, so we square -9. Otherwise, we carry out the following operation.
[tex]-9 \times -9 = 81[/tex]
Then, we see that 2 is multiplied into this value. Therefore, we multiply 81 by 2.
[tex]81 \times 2 = 162[/tex]
Now, we need to subtract the product of 5 and -9.
[tex]5 \times -9 = -45[/tex]
[tex]162 - - 45 = 207[/tex]
Finally, we subtract 20 from this value.
[tex]207 - 20 = 187[/tex]
Therefore, the value of f(-9) is 187.
[tex] \sf f(x) = 2 {x}^{2} - 5x - 20[/tex]
To Find :-[tex] \sf f( - 9)[/tex]
Solution :-[tex] : \implies \sf f( - 9) = [2 \times( { - 9}^{2} )]-[ 5 \times - 9] - 20[/tex]
[tex] : \implies \sf f( - 9) = 2 \times 81 + 45 - 20[/tex]
[tex]: \implies \sf f( - 9) = 162 + 45 - 20[/tex]
[tex] : \implies \sf f( - 9) = 207 - 20[/tex]
[tex]: \implies \bf f( - 9) = 187[/tex]

6. Tim and Jude share some
money in the ratio 3:4. If Tim gets
$450. How much did they share?
Answer:
They shared $1050.
Step-by-step explanation:
Divide 450/3 = 150
150 * 4 = 600
If Tim gets $450, then Jude will get $600.
450 + 600 = 1050
If Tim gets $400, then Jude will get $600.

Answer:
∠SAP = 85°
Step-by-step explanation:
The whole is the sum of the parts.
∠SAX = ∠SAP + ∠PAX
142° = ∠SAP + 57° . . . . . . . use the given values in the equation
∠SAP = 142° -57° . . . . . . . . subtract 57° from both sides
∠SAP = 85°
