Answer:
AN = 9
Step-by-step explanation:
so we can imagine this in a line like:
A---------------N---------------X
Step 1 : solve for x
AX=21 (our total)
because we know that AN+NX together makes AX, we put that into an equation
AN + NX = AX
(2x+1) + (3x) = 21
2x + 1 + 3x = 21 <-- subtract 1 from both sides
2x + 3x = 20 <-- add 2x +3x
5x = 20 <-- divide 5 from both sides
x = 4
Step 2 : input x into AN
AN = 2x + 1 <-- input 4 for x
AN = 2(4) + 1 <-- simplify from there
AN = 9
A sector of a circle has an arc length of π cm and a central angle of π6 radians. What is the area of the sector?
A. 5π cm²
B. 2π cm²
C. 3π cm²
D. π cm²
Answer:
C
Step-by-step explanation:
The Area of sector is π cm². so option D is correct.
How to find the area of a sector of a circle?The sector of a circle is like a slice of a circular pizza.
[tex]A = \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]
Mathematically π radians = 180 degrees
thus, π /6 radians = 180/6 = 30 degrees
The formula for the length of an arc is;
Ф/360 x 2πr
where Ф, is 30 degrees
And the arc length is pi
so we have
30/360 x 2πr = π
30/360 x 2r = 1
60r = 360
r = 360/60
r = 6 cm
Now the area of a sector is;
Ф/360 x πr^2
30/360 x π36
= π cm^2

Answer:
y=5-2x
Step-by-step explanation:
What are the values of x and y if you answer is not a whole number write it as a decimal and round if neccasasry
a) 3x + 5y = 26
b) 2x + 2y = 12
First, we need to find a way to equate either the x terms or the y terms in each equation. a) 6x + 10y = 52
b) 6x + 6y = 36
Then take equation b) from the equation a) to eliminate the x component.
a) 6x + 10y = 52
- b) 6x + 6y = 36
0x + 4y = 16
y = 4 ?
Then substitute the value of y into either equation to find the value of x.
b) 2x + 2y = 12
2x + (2x4) =12
2x + 8 = 12
2x = 4
x = 2

Meredith has two different-sized bags of trail mix. The larger bag contains 6.18 ounces of trail mix. The smaller bag contains more trail mix? Why
Answer:
The answer is "smaller bag ".
Step-by-step explanation:
Please find the complete question in the attached file.
There are more trail mixes in the smaller pack.
It's because in the smaller bag (6.8 ounces) the trail mix is more than in the bigger bag (6.18 ounces).
It was reasonable because the capacity of the bag is not stated, and both bags will contain far more than 6,8 ounces.

Answer:
∠ B = 54°
Step-by-step explanation:
Supplementary angles sum to 180°, so
7x + 7 + 4x - 14 = 180
11x - 7 = 180 ( add 7 to both sides )
11x = 187 ( divide both sides by 11 )
x = 17
Then
∠ B = 4x - 14 = 4(17) - 14 = 68 - 14 = 54°

Step-by-step explanation:
the perimeter is the sum of all numbers around the rim of the shape.
f(x)=x^2+2x-6 and g(x)=x+5
Type the composition (gof)(x) of the given functions
F ( x + 5 )= x ^2 + 12 x + 29
The composition (gof)(x) of the given functions is (g°f)(x) = x² + 12 x + 29
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
For two given functions f(x) and g(x), the composite function
(g ° f)(x) is g(f(x))
we know that:
g(x) = x+5
f(x) = x² + 2x - 6
Then:
(g°f)(x) = g(f(x))
So, we just need to evaluate g(x) in f(x):
g(f(x)) = f(x) + 5 = (x² + 2x - 6) + 5
(g°f)(x) = x² + 12 x + 29
Then the correct answer is (g°f)(x) = x² + 12 x + 29

Since you have a 180-degree angle, you can subtract it by 50. replace <2 by x
so, 50 + x = 180
180 - 50 = 130
The answer is 130 degree angle.

The perimeter of the pentagon below is 10.5 units. Four sides of this pentagon have the same length, h, and the other side has a length of 1.7 units, as shown below.
What is the value of h?
A 2.2
B 3.7
C 4.8
D 8.8
Answer:
A 2.2
Step-by-step explanation:
So the perimeter is 10.5 and one side is 1.7 and the others are the same.
The Equation for the perimeter of a pentagon is P = side + side + side + side + side.
Fill it out for the sides.
10.5 = 1.7 + 4h
8.8 = 4h
h = 2.2
Write a recursive sequence that represents the sequence defined by the
following explicit formula:
An = 1 - 5(n − 1)
Answer:
[tex]a_1=1\\a_n=a_{n-1}-5[/tex]
Step-by-step explanation:
a₁ = 1 - 5(1 - 1) = 1 - 5·0 = 1
a₂ = 1 - 5(2 - 1) = 1 - 5·1 = 1 - 5 = a₁ - 5
a₃ = 1 - 5(3 - 1) = 1 - 5·2 = 1 - 5 - 5 = a₂ - 5
a₄ = 1 - 5(4 - 1) = 1 - 5·3 = 1 - 5 - 5 - 5 = a₃ - 5
and so on, therefore:
aₙ = aₙ₋₁ - 5Gomez isn’t sure what to do. Should he put his $3000 into an account paying 6% for 10 years compounded annually or should he put into an account paying 10% for five years?
Answer:
If these are the only two options, the most profitable is the first option (6% and 10 years).
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,000
Number of periods (n)= 10 years or 5 years
Interest rate (i)= 6% or 10%
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1 + i)^n
6% interest rate:
FV= 3,000*(1.06^10)
FV= $5,372.54
10% interest rate:
FV= 3,000*(1.1^5)
FV= $4,831.53
If these are the only two options, the most profitable is the first option (6% and 10 years).
