Answer:
6
Step-by-step explanation:
to find the mean, you must add all the numbers together and divide by the amount of numbers. for example, 2+4+6+8+10=30. next, you divide 30 by the amount of numbers, which is 5. if you count there are five numbers. so 30÷5=6 :)
The manager of a store increases the price of the bathing suits by 7%. Let t be the original price of a bathing suit. The new price is t + 0.07t. A. Find an expression equivalent to t + 0.07t.
Answer:
[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]
Step-by-step explanation:
There are a couple of equivalent expressions to the function [tex]t+0.07t[/tex]. For example:
[tex]t+0.07t[/tex]
Factor:
[tex]t+0.07t=t(1+0.07)[/tex]
If you add the terms inside the parentheses:
[tex]t(1+0.07)=t(1.07)[/tex]
Basically you can add the like terms from the start and get the same result.
[tex]t+0.07t=1.07t[/tex]
Therefore:
[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]

Evaluate f(x) = –4x – 5 for x = –1. –9 –1 4 1
Answer:
f(-1) = -1
Step-by-step explanation:
f(x) = –4x – 5
Let x = -1
f(-1) = -4(-1) -5
= 4 -5
= -1
What are the solutions of the equation (x – 3)2 + 2(x – 3) -8 = 0? Use u substitution to solve.
x = -5 and x = 1
x = -1 and x = 5
x= -1 and x = -7
x = 1 and x = 7
Answer:
x = -1 and x = 5
Step-by-step explanation:
What are the solutions of the equation (x – 3)² + 2(x – 3) -8 = 0? Use u substitution to solve.
(x – 3)² + 2(x – 3) -8 = 0 -------------------------------------------------------(1)
To solve this problem, we will follow the steps below;
let u = x-3
we will replace x-3 by u in the given equation:
(x – 3)² + 2(x – 3) -8 = 0
u² + 2u -8 = 0 ----------------------------------------------------------- --------------(2)
We will now solve the above quadratic equation
find two numbers such that its product gives -8 and its sum gives 2
The two numbers are 4 and -2
That is; 4×-2 = -8 and 4+(-2) = 2
we will replace 2u by (4u -2u) in equation (2)
u² + 2u -8 = 0
u² + 4u - 2u -8 = 0
u(u+4) -2(u+4) = 0
(u+4)(u-2) = 0
Either u + 4 = 0
u = -4
or
u-2 = 0
u = 2
Either u = -4 or u = 2
But u = x-3
x = u +3
when u = -4
x = u + 3
x = -4 + 3
x=-1
when u = 2
x = u + 3
x = 2 + 3
x=5
Therefore, x = -1 and x =5

X=1-y, 6x+5y=11 using substitution method
Answer:
x=6 y=-5
Step-by-step explanation:
6x+5y=11
X=1-y
6x=6(1-y)
6x=6-6y
6-6y+5y=11
6-y=11
y=-5
x=1-y
x=1-(-5)
x=6
so,
x=6
y=-5
Answer:
[tex]y = ( - 5) \\ x = 6[/tex]
Step-by-step explanation:
[tex]x = 1 - y \\ 6x + 5y = 11 \\ \\ \\ 6(1 - y) + 5y = 11 \\ 6 - 6y + 5y = 11 \\ - 6y + 5y = 11 - 6 \\ - y = 5 \\ y = - 5[/tex]
[tex]x = 1 - y \\ x = 1 - ( - 5) \\ x = 1 + 5 \\ x = 6[/tex]
Let's check whether the answer is correct.
[tex]6x + 5y = 11 \\ 6 \times 6 + 5 \times ( - 5) = 11 \\ 36 - 25 = 11 \\ 11 = 11[/tex]

area of the shaded segment of a circle. radius is 10 arc measures 90 degrees
Answer:
[tex]25\pi[/tex] or about 78.54 units
Step-by-step explanation:
Since the arc measures 90 degrees, since 90/360=1/4 the segment is 1/4 of the area of the circle. The whole area of the circle is [tex]\pi 10^2=100\pi[/tex], meaning that the area of the segment is [tex]25\pi[/tex] square units, or about 78.54. Hope this helps!

3x + 4 = 13 solve for X
Answer:
x = 3
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
First, subtract 4 from both sides:
3x + 4 (-4) = 13 (-4)
3x = 13 - 4
3x = 9
Next, divide 3 from both sides:
(3x)/3 = (9)/3
x = 9/3
x = 3
3 is your answer for x.

then MN =
A. 7
B. 8
C. 9
Answer:
The measure of [tex]MN[/tex] :
[tex]MN = 8[/tex]
Step-by-step explanation:
To find the measure of [tex]MN[/tex], add the measure of [tex]RO[/tex] and [tex]ES[/tex] together and divide it by 2 to get the actual measure of [tex]MN[/tex]:
[tex]RO =[/tex] 10
[tex]ES =[/tex] 6
[tex]MN =[/tex] unknown
-Finding the measure of [tex]MN[/tex]:
[tex]10 + 6 = \frac{16}{2} = 8[/tex]
[tex]MN = 8[/tex]
So, the measure of [tex]MN[/tex] would be [tex]8[/tex] .

Step-by-step explanation:
The graph of the function f (x) = StartFraction 6 Over x minus 3 EndFraction is shown below. On a coordinate plane, a hyperbola is shown. Both curves approach x = 3. What is the vertical asymptote of the function? x = –3 x = –2 x = 0 x = 3
Answer:
D.) x=3
Step-by-step explanation:
its right
The function will form a vertical asymptote at [tex]x=3[/tex].
Option D: [tex]x=3[/tex] is correct.
Given:
The function is [tex]f (x) = \dfrac{ 6} { x - 3 }[/tex].
We need to find the vertical asymptote of the function.
The given function is a rational function in which the denominator is [tex]x-3[/tex].
Now, the denominator should not be equal to zero.
As the function approaches [tex]x=3[/tex], the function will lead to infinity (positive or negative).
So, the function will form a vertical asymptote at [tex]x=3[/tex].
Option D: [tex]x=3[/tex] is correct.

Please refer to the attached image for the detailed labeling of all the sides.
[tex]\triangle ABC[/tex] is the triangular base of the prism.
BC is the base of triangular base of the prism.
AP is the height of triangular base.
Area of triangular base is represented by B and is calculated by following formula of area of a triangle.

Find the area of each sector. Photo attached
Answer:
Area of sector: 48π in^2; Option D
Step-by-step explanation:
~ We can see that the bolded portion of the circle must be the the sector that we need to compute the area of... ~
Let us plan out this problem. If we were to find the area of the circle provided a radius of 12 inches, we could create a proportionality between the degree of the sector, and the degree of the circle ( 360 ) and the area of the sector and the area of the circle.
1. To calculate the area of this circle, let us apply the formula πr^2, such that r is 12 inches ( and let us keep π in terms of π ) ⇒ π * ( 12 )^2 ⇒ 144 * π ⇒ Area of Circle: 144π
2. Let us see this as a proportionality:
Degree of sector/ Degree of circle = Area of sector/ Area of circle
3. Now let us say x ⇒ Area of the sector. Substitute values into this formula, and solve for x through algebra:
120 / 360 = x / 144π,
120 * 144π = 360 * x,
17,280π = 360 * x,
x = 17,280π / 360,
Area of sector: 48π in^2

In your piggy bank, you have 15 quarters, 2 dimes, 1 nickel and 32 pennies. You tip the bank, and out rolls one, then another , then another coin. Find the probability that the coins came out as the follows:
a) 1 penny, 1 quarter, 1 dime
b) 1 penny, 1 quarter, 1 penny
Please show work. Thank You!
Answer:
B) Is the answer.
Step-by-step explanation:
If you have 15 quarters and 32 pennies, you have more than twice the amount of pennies that you do quarters. There is a small chance that it could be a dime or a nickel but this is unlikely. The chance of a quarter and penny falling out is much greater than a dime or nickle.
