Answer:
I think it would be D, but can you correct me if I'm wrong :)
Step-by-step explanation:
If it's + 3, it will move over to the right 3 times
Hope that this helps you and have a great day :)
I'm not sure how the correct way to do this would be but if you have a ratio that is 5:2 think of it as having 5 groups of animals and 2 groups of animals.
Find the number by dividing the total amount of animals 98/7 = 14.
We know that there are 5 groups of cats, the ratio for 5 cats. 14 x 5 = 70.
The remainder is dogs, which has a ratio of 2:5. 14 x 2 = 28.
70 + 28 = 98.
Answer:
<u>About 8.5 mins</u>
Step-by-step explanation:
This is a compound decay problem, which goes by the formula:
Where
F is the future amount (we want it to be 380)
P is the present amount (980 now)
r is the rate of decay per minute (10.5% = 10.5/100 = 0.105)
t is the time it takes (what we want to find)
Substituting, we get our answer to be:
SO, it is going to take about 8.54 mins, rounded to nearest tenth (1 decimal), we have:
<u>About 8.5 mins</u>
Answer:
2 2/3 hours
Step-by-step explanation:
Before it was 5 hours for 1 guitar, or 5 hours/guitar
Now it is 7 guitars in 3 hours or 7/3 hours/guitar
7/3 = 2 1/3
5 hours - 2 1/3 hours = 15/3 hours - 7/3 hours = 8/3 hours = 2 2/3 hours
The reduced the time it takes to build 1 guitar by 2 2/3 hours.
Answer:
A
Step-by-step explanation:
To calculate the scale factor k, find the ratio of corresponding sides
= = 6
= = 6
Hence the scale factor k = 6 → A
