Answer: The difference in temperature is -44 degrees.
Explanation: Since the new temperature is a negative number and the old was positive, you add them together. However instead of (-5) +39 (which the answer would be 35), you would write 5 +39 because -5 is 5 spaces away from 0. You can also check by using the equation 39 -44. You would get the answer -5, proving that the answer is indeed -44 degrees.
The only way I can see to work this out is long hand writing out all prime numbers multiply them by 2 and looking for prime number interferes therefore = 3+7=10
Answer:
5/6 minutes x 60 = 50
1/3 minutes x 60 = 20
I got my answer by multiplying by 60 since there are 60 min in one hour.
Using the keyword 'of" it means to multiply so multiply your two given numbers.
Answer:
There will be viewers in 1 year
640 people will see the video on 7th day
Step-by-step explanation:
On the day a video was posted online, 5 people watched the video.
Initial viewers = 5
The next month the number of viewers had doubled.
Assume the number of viewers continues to double each day.
Formula:
Where a is the initial amount
b is the rate
t is time in days
1) We are supposed to find the no. of viewers in 1 year
1 year =
So,
2)Estimate on which day will 640 people see the video?
So, y = 640
So,
So, t = 7
Hence 640 people will see the video on 7th day
Answer:
Each hotdog costs $1.65
Each juice drink costs $1.05
Step-by-step explanation:
Let's begin by letting represent the number of hot dogs and the number of juice drinks.
The Baxter family bought 6 hot dogs and 4 juices for $14.10.
The Farley family bought 3 hot dogs and 4 juices for $9.15.
Now, we subtract these equations.
Since has reversed coefficients, it gets eliminated. Now solve for x.
NOW, we find y by substituting x with 1.65 (in either equation).
We'll use the first equation.
= 1.65
= 1.05
represents hotdogs and represents juice drinks.
Therefore, each hotdog costs $1.65 and each juice drink costs $1.05.
