Answer:
420 m^2
Step-by-step explanation:
Ancho: x
Largo: 2x + 2
2x + 2(2x+2) = 88
2x + 4x + 4 = 88
6x = 88 - 4
x = 84/6
x = 14
Ancho: 14
Largo : 30
Area: 14 * 30 = 420 metros cuadrados
Answer:
1500 people
Step-by-step explanation:
Since 40% are HIV positive (that's a lot of people), 60% will be HIV negative. All you have to do is find 60% of 2500.
60% of 2500 = 0.6 * 2500 = 6 * 250 = 1500
Hope this helps!
Since in the above case, the beaker has two sections each with different radius and height, we will divide this problem into two parts.
We will calculate the volume of both the beakers separately and then add them up together to get the volume of the beaker.
Given, π = 3.14
Beaker 1:
Radius (r₁) = 2 cm
Height (h₁) = 3 cm
Volume (V₁) = π r₁² h₁ = 3.14 x 2² x 3 = 37.68 cm³
Beaker 2:
Radius (r₂) = 6 cm
Height (h₂) = 4 cm
Volume (V₂) = π r₂² h₂ = 3.14 x 6² x 4 = 452.16 cm³
Volume of beaker = V₁ + V₂ = 37.68 + 452.16 = 489.84 cm³
Answer:
Step-by-step explanation:
I'm guessing we are missing a piece of the question such as the average speed at which Nadeem can ride. Let's call it v
distance is a product of velocity and time
d = vt
t = d/v
so if v is in miles/hr, an inequality could be
12/v ≤ t ≤ 15/v
