Answer:
20m
Step-by-step explanation:
Area of garden = 400m²
Area = L² = 400m²
L = √400m²
L = 20m
Answer:
(3 and 15)
Step-by-step explanation:
If the product of both of these two numbers needs to be a negative 45 then there are no pair of integers that comply with both requirements.
If the multiplication in the question is wrong and it is a positive 45 then the pair of integers that would comply with these requirements would be (3 and 15). Multiplying this pair together would give you 45 and the difference between them is also 12 meaning it complies with both requirements that were asked for in the question.
B
the volume (V) of a sphere =
πr³
We require to know the radius r to calculate the volume
using surface area of a sphere = 4πr² = 615.752
divide both sides by 4π
r² =
= 49.0248...
take the square root of both sides
r =
≈ 7, hence
V=
× π × 7³ = 1436.76 m³ → B
Answer:
125
Step-by-step explanation:
x(t) = x0 × (1 + r) t
where:
x(t) = the amount of some quantity at time t
x0 = initial amount at time t = 22
r = the growth rate
t = time
