Help PlzzzWhich Of The Following Is NOT An Equivalent Expression To Area Of Sector =

Answers

Answer 1

Answer:

Step-by-step explanation:

Answer 2

From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.

What is the area of a circular sector?

The area of the circular sector is the space occupied by it. The area of the circular sector is the half of the product of the angle of the sector and the radius of the circle. It can be given as,

[tex]A_s=\dfrac{r^2\theta}{2}[/tex]

Here, (r) is the radius of the circle and θ is the angle of the sector. Multiply with π/180 to convert it into the degrees.

[tex]A_s=\dfrac{r^2\theta}{2}\left(\dfrac{\pi}{180}\right)\\A_s={\pi r^2}\left(\dfrac{\theta}{360}\right)[/tex]

Thus, the option D is correct. Now, πr² is the area of circle . Thus,

[tex]\rm \text{Area of sector}=\dfrac{(Area\; of \;Circle)(Arc\; Measure)}{360^o}\\\rm \dfrac{(Area\; of \;Sector)}{(Arc\; Measure)}=\dfrac{\text{Area of sector}}{360^o}[/tex]

From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.

work out a and b

I dont really care about the answer I just want the working out and the reason why​

Answers

Answer:

a=5 b=8

Step-by-step explanation:

[tex] {(a {r}^{b} )}^{3} = 125 {r}^{24} [/tex]

[tex] {(a {r}^{b} )}^{3} = {5}^{3} {r}^{24} [/tex]

{125 = 5×5×5 = 5³}

[tex]{(a {r}^{b} )}^{3} = {(5 {r}^{8}) }^{3} [/tex]

{Taking 3 power outside to get 5r⁸}

{Then match the positive integer with a and b}

Therefore,

a= 5

b= 8

<b= 48 degree

Step-by-step explanation:

<B = 2x + 14 degree

<C = 4x - 26 degree

[tex]90+2x+14+4x-26=180 degree\\2x+4x=180+26-90-14\\6x=102\\x=\frac{102}{6} \\x=17 degree\\[/tex]

By the fiftieth year, there will be 112 wolves ([tex]y = 2[/tex] × [tex]50 + 12[/tex])

Step-by-step explanation:

You start with 12 wolves in the population.

Each year, the wolf population will increase by 2 years.

Let x represent the number of years.

Let P represent the total population.

Considering all this, P = 2x + 12.

In this case, we want to find how many wolves will be in the population in 50 years. Therefore, we will need to plug 50 into the equation in place of x.

P = 2(50) + 12

A small school has 78 students. If 24 students are boys what is the ratio of girls to boys​

Answers

54:24
Explanation:
If there’s 78 students, and you subtract 24, you’re left with 54, therefore your answer would be 54:24

Answer:

54 : 24

Step-by-step explanation:

Total: 78 students

Part (boys): 24 students

We can find the number of girls in the school by subtracting the number of boys from the total number of students.

Part (girls): Total - Part (boys) = 78 - 24 = 54

We now have the amount of girls and boys, so we can rewrite as a ratio of girls to boys.

Girls: 54

Boys: 24

Girls : Boys = 54 : 24

You have a pile of 45,000 candies. You are going to give away 18% every day. USING THE EXPLICIT EQUATION how many candies will you have left after 5 days. Round you answer to the nearest whole candy

Answers

Answer:

16683 candies

Step-by-step explanation:

Given:

Initial value is 45000.Reduction per day is 18%.

The equation would be:

[tex]C(t) = 45000*(1 - 0.18)^t=45000*0.82^t[/tex], where C(t) is the number of candies left after t days

Find the value of C(5):

C(5) = 45000*0.82⁵ ≈ 16683 rounded

[tex]\\ \sf\longmapsto C(t)=P\left(1-\dfrac{R}{100}\right)^t[/tex]

[tex]\\ \sf\longmapsto C(t)=45000\left(1-\dfrac{18}{100}\right)^t[/tex]

[tex]\\ \sf\longmapsto C(t)=45000(1-0.18)^t[/tex]

[tex]\\ \sf\longmapsto C(t)=45000(0.82)^t[/tex]

Now

[tex]\\ \sf\longmapsto C(5)=45000(0.82)^5[/tex]

[tex]\\ \sf\longmapsto C(5)=45000(0.37)[/tex]

[tex]\\ \sf\longmapsto C(5)\approx16650[/tex]
