Answer:

8 pieces of candy

Step-by-step explanation:

Take the original amount of candy in the bowl to be x.

It says that 20 pieces of candy were added, therefore there are x+20 pieces of candy in the bowl.

Half of the candy is gone, therefore \frac{x+20}{2} pieces of candy are left in the bowl.

After half of the candy is gone, there are 14 pieces left, so we can say that \frac{x+20}{2} =14

Solve for x:

x+20 = 28

x=8

A community pool that is shaped like a regular pentagon needs a new cover for the winter months. the radius of the pool is 20.10
inn [45]

The area of the pool that needs to be covered is 960.42 square feet.

<h3>What is Pythagoras theorem give example?</h3>
  • To determine the undiscovered side of a right-angled triangle, utilize the Pythagoras theorem.
  • The hypotenuse (third side) of a right-angled triangle, for instance, can be determined using the formula c2 = a2 + b2, where 'c' stands for the hypotenuse and 'a' and 'b' are the two legs.

According to the question:

  • We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.
  • To find the area of community pool we will use area of pentagon formula.
  • Area of pentagon=\frac{1}{2} a * p$ , where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.

Let us find the perimeter of our given pentagon by multiplying each side length by 5.

Perimeter of community pool $=5 \times 23.62\\Perimeter of community pool $=118.1$

Now let us find apothem of our pentagon by using Pythagoras theorem.  

a^{2}=20.10^{2}-11.81^{2}\\$a^{2}=404.01-139.4761\\$a^{2}=264.5339\\$a=\sqrt{264.5339}\\$a=16.2645$

Upon substituting our given values in above formula we will get,

Area of community pool =\frac{1}{2} \times 16.2645 \times 118.1\\Area of community pool $=8.13224907 \times 118.1\\Area of community pool $=960.418615627971 \approx 960.42$

Therefore, the area of the pool that needs to be covered is 960.42 square feet.

Hello,

The answer will be "-5+2".

Reason:

I These lines turn negative numbers into positive:

Therefore the answer will be -5+2 (since how the first - sign was outside of the I).

If you need anymore help feel free to ask me!

Hope this helps!

The center of a circle represented by the equation (x+9)^2 + (y-6)^2 =10^2 is what
inysia [295]

Answer:

A

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 9)² + (y - 6)² = 10² is in this form

with centre = (- 9, 6) → A
