What is the value of x in the figure?
A. 40
B. 70
C. 80
D. 120
E. 150
Answer:
E) 150°
Step-by-step explanation:
angle adjacent to 70° angle is 110°
the angle supplemental to 'x' must be 180-(40+110) or 30°
this means 'x' must be 150°
Which value is equivalent to √-25
What is the recursive and explicit formula of the geometric sequence?
2,5, 12.5, 31.25, 78, 125, ...
Answer:
Option (2)
Step-by-step explanation:
Given geometric sequence is,
2, 5, 12.5, 31.25, 78.125......
First term = a₁ = 2
Common ratio of the sequence = r = [tex]\frac{5}{2}[/tex]
= 2.5
Recursive formula of a geometric sequence is given by,
[tex]a_n=a_{n-1}(r)[/tex]
Here, [tex]a_n=[/tex] nth term of the sequence
[tex]a_{n-1}=[/tex] (n - 1)th term
r = common ratio
Therefore, recursive formula for the given sequence will be,
[tex]a_1=2[/tex]
[tex]a_n=a_{n-1}(2.5)[/tex]
Explicit formula of a geometric sequence is given by,
[tex]a_n=a_1(r)^{n-1}[/tex]
Therefore, explicit formula of the sequence will be,
[tex]a_n=2(2.5)^{n-1}[/tex]
Option (2) will be the correct option.
Which expression is equivalent to 12n - 6x + 48 ?
A. 6 (2n - x + 8 )
B. 6nx +48
C. 2(6n + x ) +48
D. 12n - 6 (x + 4)
Answer:
A. 6 (2n - x +8)
Step-by-step explanation:
Answer:
6(2n-x+8)
Step-by-step explanation:
If a number is in front of the bracket it means times everything on the inside by that number.
So you times everything by 6.
6×2n=12n
6×-x= -6x
6×8=48
Then you put it into an equation:
12n-6x+48
Hope this helps :)
How are formulas for the volume of a cylinder, pyramid, and cone derived?
Answer:
Calculus-based analytic geometry makes the cylinder, pyramid, and cone from "solids of revolution". From there, they can measure the length or radius of the base, and then the height. This is true even if the solid of revolution is along the X axis intead of the Y axis. Then someone "figured out" the formula, just like they did with a cube, and proved it.
A ladder that is 6 meters long leans
against a building. The base of the
ladder is 1.5 meters from the base
of the building. To the nearest
hundredth of a meter, how far up
the building does the ladder reach?
Answer:
Height of building from base to ladder = 5.8 meter (Approx.)
Step-by-step explanation:
Given:
Length of ladder = 6 meters
Distance of ladder from base = 1.5 meters
Find:
Height of building from base to ladder
Computation:
Perpendicular = √Hypotenuse² - Base²
Height of building from base to ladder = √Length of ladder² - Distance of ladder from base²
Height of building from base to ladder = √6² - 1.5²
Height of building from base to ladder = √36 - 2.25
Height of building from base to ladder = √33.75
Height of building from base to ladder = 5.8 meter (Approx.)

At a carnival, Ivan bought 9 packs of 16 tickets each. He has used 35 of the tickets so far. How many tickets does he have left?
Answer:
He has 109 tickets left!
Step-by-step explanation:
ok, let's find out how many tickets he bought in total!
he bought: 9 packs with 16 tickets inside each pack
so...
9 x 16 = 144
144 - 35 = 109
Make sure to double check before writing it down!
45 + 9/4 + 4 + 12/20
45 + 2.25 + 4 + 0.6 =
45 + 6.85 =
51.85

Using the figure at the left, complete the extended similarity statement:
ΔUVW ∼ Δ _______ ∼ Δ __________
Answer:
[tex]\triangle {UVW} \sim \triangle {UVA} \sim \triangle {UAW}[/tex]
Step-by-step explanation:
The triangles UVW, UVA and UAW, since all three are right angles and have the same combination of angles, meaning the existence of proportionality between corresponding lengths. That is:
[tex]UA \propto AV \propto UV[/tex], [tex]AW \propto UA \propto UW[/tex], [tex]UW \propto UV \propto WV[/tex]
Hence, the complete similarity statement is:
[tex]\triangle {UVW} \sim \triangle {UVA} \sim \triangle {UAW}[/tex]

I NEED THIS ANSWERED ASAP PLEASE HELP!!! select the correct answer for points
Answer:
C. 120°
Step-by-step explanation:
length of arc = 4π cm
r = 6 cm
central angle = s/r
=> central angle = 4π/6
=> central angle = 2π/3 radians
In degrees,
central angle = (2π/3)(180/π) = 120°
hope this helps and is right. p.s i really need brainliest :)
If the perimeter of a square is 28 inches and the area of the square is (x2 + 4x + 4) square inches, where x is a positive number, what is the value of x?
Answer:
If the perimeter of a square is 28 inches and the area of the square is (x2 + 4x + 4) square inches, and x is a both a real and a positive number, then the value of x must be 5.
Step-by-step explanation:
All sides of a square are equal length.
The area of a square is the side length squared.
perimeter p, side length s, area a, and variable x.
p = 28. s = ? a = x^2 + 4x + 4. x = ?
p = 28
p = 4s.
28 = 4s.
7 = s.
a = s^2.
s = 7.
a = 7^2.
a = 49.
a = x^2 + 4x + 4.
a = 49.
x^2 + 4x + 4 = 49.
factor x^2 + 4x + 4.
(x+2)(x+2) = 49.
(x+2)^2 = 49.
√ ((x+2)^2) = √49.
take positive answer.
x+2 = 7
x = 5.
What is the solution to the equation below?
Answer:
The solutions are (2,0) and (3,0)
Step-by-step explanation:
The common denominator is (x - 2)(x - 4) which comes to x^2 - 6x + 8 which is exactly what the denominator on the right hand side is.
2x (x - 4) - (x+3)(x - 2) = - 4x
============= ========
(x -2)(x - 4) x^2 - 6x - 8
Multiply both sides by x^2 -6x - 8
2x(x - 4) - (x^2 + x - 6 ) = - 4x Remove the brackets
2x^2 - 8x - x^2 - x + 6 = - 4x Combine like terms on the left
2x^2 - x^2 - 8x - x + 6 = - 4x
x^2 - 9x + 6 = - 4x Add 4x from both sides
x^2 - 9x + 4x + 6 = 0
x^2 - 5x + 6 = 0
This factors into
(x - 2) and (x - 3)
x - 2 = 0
x = 2
x - 3 = 0
x = 3
In 1945, a microwave cost $435. Today, a microwave costs $130. What is the percent of change?
Answer:
29.89%
Step-by-step explanation:
Step 1: We assume that 435 is 100% since it is our output value.
Step 2: We next represent the value we seek with [tex]$x$[/tex].
Step 3: From step 1, it follows that [tex]$100\%=435$[/tex].
Step 4: In the same vein, [tex]$x\%=130$[/tex].
Step 5: This gives us a pair of simple equations:
[tex]100\%=435(1)\\\\x\%=130(2)[/tex]
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left-hand side) of both equations have the same unit (%); we have
[tex]$\frac{100\%}{x\%}=\frac{435}{130}$[/tex]
Step 7: Taking the inverse (or reciprocal) of both sides yields
[tex]\frac{x\%}{100\%}=\frac{130}{435}\\\\\Rightarrow x=29.89\%[/tex]
Therefore, [tex]$130$[/tex] is [tex]$29.89\%$[/tex] of [tex]$435$[/tex].

Can a triangle have two 30° angles? two 60° angles? two 90° angles? Explain.
Answer:
Step-by-step explanation:
Two 30 - yes, 180 - 30 - 30 = 120. It is possible for 2 angles to be 30, the remaining angle would also be 120
Two 60 - yes, 180 - 60 - 60 = 60. It is possible for 2 angles to be 60, the remaining angle would also be 60
Two 90 - Not possible. The entire angles of a triangle have to equal 180, this would mean only 2 angles.

GOD BLESS WHAT IS THE ANSWER TO THIS?
Answer:
Option 1
Step-by-step explanation:
It's asking me to write 20 words so blah blah blah.
help ASAP PLEASE look like a
Answer: B. 1
Step-by-step explanation: A common factor is something that two or more numbers have in common. It is 1 because you multiply 1 by 1 to get 1, and 1 by 2 to get 2.
(1 by 1) = 1
(2 by 1) = 2
These two numbers have the number 1 in common because both 1 and 2 can only be multiplied by 1 and itself to get the number. (That is also what you call prime numbers.)
