Answer:
Rate = 0.035 per weeks
Step-by-step explanation:
Given that,
An artist has completed 1/14 of a painting in 2 weeks.
We need to find the rate at which she is working. Let the rate is R. It can be calculated by dividing part that is completed and time.
Hence, her rate is 0.035 per weeks.
The answer would be the bottom left one because 5.15 round to 5 and 42,980 rounds to 40,000 which is equal to 4x10^4 (4 zeros). Then you subtract the exponents and divide the other terms to get 1.25x10^2
Answer:
Step-by-step explanation:
Given
(a) to (d)
Required
Which will give:
Equate the expression in bracket to g(x)
Replace g(x) with x in:
Step-by-step explanation:
The problem statement says λ<1. If this is true, then the cannonball is slower than the boat, and it will never reach the boat. So I assume it's actually λ>1.
If we say t is the amount of time, then the boat travels south a distance of ut, and the cannonball travels a distance of λut.
v = λut
ut = v/λ
Using Pythagorean theorem:
d² + (ut)² > v²
d² + (v/λ)² > v²
λ²d² + v² > λ²v²
λ²d² > (λ² − 1) v²
λ² / (λ² − 1) > (v/d)²
The answer for 30% of 80 is “20”
