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°

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

Answers

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

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

Answers

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.

Gomez 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?

Answers

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).

Answers

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

Answers

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

Write a recursive sequence that represents the sequence defined by the
following explicit formula:
An = 1 - 5(n − 1)

Answers

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

a = 1 - 5(2 - 1) = 1 - 5·1 = 1 - 5 = a - 5

a = 1 - 5(3 - 1) = 1 - 5·2 = 1 - 5 - 5 = a - 5

a = 1 - 5(4 - 1)  = 1 - 5·3 = 1 - 5 - 5 - 5 = a - 5

and so on, therefore:

                              aₙ = aₙ₋₁ - 5
