answer: 400 athletes

explanation: 35 + 21 + 14 = 70 total students surveyed. 35 of the students select water (35/70) which is equal to 1/2 so you can do 800 divided by 1/2 and you’ll get 400 :)

The sum of the interior angles of s regular polygon is 3960, how many sides does it have?

Tju [1.3M]

The equation for the sum of interior angles is :

Sum = (n-2) x 180, where n is the number of sides.

Replace sum with the given sum:

3960 = (n-2) x 180

Divide both sides by 180:

22 = n-2

Add 2 to each side:

24 = n

It has 24 sides.

For Each interior angle, divide the total sum by the number of sides:

3960 / 24 = 165 degrees

The interior and exterior angle needs to equal 180 degrees. To find the exterior angle, subtract the interior angle from 180:

180 - 165 = 15 degrees.

PLSSSSSSSS HELLPPPPPP.......Which triangle’s unknown side length measures StartRoot 53 EndRoot units?

Orlov [11]

The right answer is Option 2: A right triangle with side length of √47 and hypotenuse of 10.

Step-by-step explanation:

We know that;

$a^2 + b^2 = c^2$

We will put the unknown length as √53 to check the solution.

Option 1: a = 6 , b = √53 , c = √91

$(6)^2+(\sqrt{53})^2=(\sqrt{91})^2\\36+53=91\\89\neq 91$

Option 2: a=√47, b = √53, c = 10

$(\sqrt{47})^2+(\sqrt{53})^2=(10)^2\\47+53=100\\100=100$

Option 3: a = √19, b=√53, c= √34

$(\sqrt{19})^2+(\sqrt{53})^2=(\sqrt{34})^2\\19+53=34\\72\neq 34$

Option 4: a=√73, b=√53, c=20

$(\sqrt{73})^2+(\sqrt{53})^2=(20)^2\\73+53=400\\126\neq 400$

Option 2 satisfies pythagoras theorem.

Therefore;

The right answer is Option 2: A right triangle with side length of √47 and hypotenuse of 10.

The sum of two integers is 310. if one of them is - 52. find the other

Elanso [62]

Answer:

Integer = 362

Step-by-step explanation:

Let the two integers be x and y

Sum of two integers, x + y = 310 ------(1)

Given one of the integer, Let x = -52

Substitute x = -52 in (1) ,

-52 + y = 310

y = 310 + 52

y = 362
