Answer:
Both sports = 15
Step-by-step explanation:
Remark
What an interesting question. At first I didn't think it was possible. Then I saw the word only. That made all the difference in the world.
Givens
Football only = 35
Volleyball only = 15
Ratio = 5/3
Equation
Let the number of students who play both = x
Volleyball / Football = (x + 15) /(x + 35) = 3/5
Solution
(x + 15) / (x + 35) = 3/5 Cross multiply
5*(x + 15) = 3(x + 35) Remove the brackets
5x + 75 = 3x + 105 Subtract 3x from both sides
<u>3x 3x</u>
2x + 75 = 105 Subtract 75 from both sides
<u> - 75 -75 </u>
2x = 30 Divide by 2
2x/2 = 30/2
x = 15
15 people play both sports.
Hello :
<span> the equation of the circle is (x-a)²+(y-b)² = r²
A(a;b) center r : </span><span>radius
</span>in this exercice : (x+3)²+y²=25
Responder:
3 m
Explicación paso a paso:
Dado que:
Longitud, L = 25 m
Ancho, W = 8 m
Volumen = capacidad = 600.000 litros
1m³ = 1000 litros
x = 600.000 litros
600.000 litros / 1000 = 600 m³
Volumen = Largo * ancho * alto
600 = 25 * 8 * h
600 = 200 horas
h = 600/200
h = 3 m
The length of the swimming pool is, 230 centimeters in length, and 216 centimeters in width. How I got my answer.
I first divided 446÷2=223, then I subtracted 223-7=216, that's width. Now I realise that there is 7 remaining, so I added 223+7=230, that's length!!
So to double check my work I added the width and length together, 216+230=446.
I hope this helps!
Answer:
(0,-4) (-8,0)
Step-by-step explanation:
x = 0, y = -4
y=0, x = -8
