First, find out how many messages are received a second. Do this by dividing messages by 60 seconds.
120/60 = 2 messages a second
now multiply 2 by 150
2*150 = 300messages in 150 seconds
your answer is (3) 300
Answer:
c. 24/25
Step-by-step explanation:
1. Use SOH CAH TOA
2. Highlight C, so you know what your looking for
3. Since were finding the cosine of C we need the side adjacent(next to) and the hypotenuse of C. We know this because of CAH(cosine= adjacent/hypotenuse
4. C is closest to 24 so we have our adjacent side as 24, this will be the numerator
5. Then find the hypotenuse, which is opposite of the 90 degree angle, marked by the square box in the triangle
6. Our Hypotenuse is 25, which will be our denominator
<h3>7. Giving the answer is 24/25</h3>
Answer:
Step-by-step explanation:
6x+14=50
(6x is hourly wage, x being the hours, 14 is the amount he started with, and 50 is what he needs)
6x=36
x=6 hours
Answer:
2 2/5
Step-by-step explanation:
5/6 x-4 = -2
Add 4 to each side
5/6 x-4+4 = -2+4
5/6 x = 2
Multiply by 6/5 to isolate x
6/5 *5/6 x = 6/5 *2
x = 12/5
Changing this from an improper fraction
5 goes into 12 2 times with 2 left over
x = 2 2/5
Answer: 16 g
Step-by-step explanation:
We can solve this with the Radioactive Half Life Formula:
Where:
is the final amount of radioactive calcium
is the initial amount of radioactive calcium
is the time elapsed
is the half life of radioactive calcium
Solving with the given data:
This is the amount of radioactive calcium left
