18·0.05= 0.9
0.9+18= 18.90
Even will earn $18.90 dollars an hour.
Answer:
8
Step-by-step explanation:
dog=3x
cat=x
3x+x=32
4x=32
4/4
32/4
x=8
3(8)=24
x=8
So she trained 24 dogs and 8 cats
The equation would be y = -5x - 7
Answer:
n = 18 cycles
Step-by-step explanation:
To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:
(1)
f: frequency of the oscillation of the current
t: time = 0.30s
The frequency is the number of cycles per second, that is, f = 60 cycles/s
You replace the values of f and t in the equation (1):

In 0.30s the current oscillates 18 times
Answer: he used incorrect time ratio
He incorrectly concluded that she is not running fast enough
