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
7(x + 2) = 6(x + 5) solve for x
X = 16
7 x + 14 - 6 x = 30
x + 14 = 30
Samantha runs 3 miles every 2 days. How many days would it take her to run 24 miles
Answer:
16
Step-by-step explanation:
3 miles = 2 days
24 miles = ? days
24 / 3 = 8
8 x 2 = 16
Answer:
16 days
Step-by-step explanation:
[tex]\frac{3}{2}[/tex] to represent the relationship from miles to days
[tex]\frac{3}{2}[/tex]=[tex]\frac{24}{x}[/tex]
3 x 8 = 24
so do the same thing to 2
2 x 8 = 16 days

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.

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°
1. Find the volume of a cube with a side of 9 cm.
2. Find the perimeter of a rectangle whose length is 4
cm and breadth is 3 cm.
3. Find the area of a square of side 11 m.
4. Find the area of a rectangle that is 14 m long and 5
m wide.
5. Find the perimeter of an equilateral triangle with
side 15 cm.
I'm in tension right now I am studying for exams and I'm tired it would be nice if you help me out!
Step-by-step explanation:
1. Given,
Side of the cube = 9 cm
Therefore, volume of the cube = side × side × side
= 9cm × 9cm × 9cm
[tex] = 729 {cm}^{3} (ans)[/tex]
2. Given,
Length of the rectangle = 4cm
Breadth of the rectangle = 3cm
Therefore, perimeter of the rectangle = 2(l+b)
= 2(4cm + 3cm) = 2 × 7cm = 14 cm (Ans)
3. Given,
Side of a square = 11 m
Therefore, area of the square = side × side
= 11 m × 11 m
[tex] \: = {121cm}^{2} (ans)[/tex]
4. Given,
Length of the rectangle = 14 m
Width of the rectangle = 5 m
Therefore, area of the rectangle = l × b
= 14 m × 5 m
[tex] = 70 {m}^{2} (ans)[/tex]
5. Given,
Side of the equilateral triangle = 15 cm
Therefore, perimeter of the triangle = 3 × side
= 3 × 15 cm = 45 cm (Ans)

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

what is the formula of cylinder
Answer:
V = πr²h
Step-by-step explanation:
r = radius of circle
h = height of cylinder
Step-by-step explanation:
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . ... Therefore, the volume of the cylinder is about 3016 cubic centimeters.
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.
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]
