Apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
<u>Solution:</u>
Need to determine what operation is required to get one-tenth of a number and 10 times of a number
To get one tenth of a number, divide the number by 10.
For example to get one – tenth of 100, divide it by 10, we get 10 as a result.
To get ten times of a number, multiply the number by 10
For example 10 times of 10 = 10 x 10 = 100
Hence apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
Answer:
A and D
Step-by-step explanation:
These dot plots show the ages (in years) for a sample of two types of fish. Wat are the differences between the centers and spreads of these distributions? Select two choices: one for the centers and one for the spreads.
A. Centers: The sharks have a lower median age than the koi.
B. Spreads: The ages of the sharks are more spread out.
C. Centers: The sharks have a greater median age than the koi.
D. Spreads: The ages of the koi are more spread out.
The answer is the last option (Option D), which is:
D. 25
The explanation is shown below:
1. You have that:
(a ± b)^2=a^2 <span>± 2ab + b^2
2. The expression given in the problem is:
</span><span>x^2-10x+n
Where x^2=a and 2ab=10x
2b=10
b=10/2
b=5
3. Therefore, you have:
b^2=5
b^2=25
b^2=n
n=25</span>
Don’t know the answer to the question but I don’t know the answer question mark I don’t know what about it I don’t I don’t know I just really don’t know I don’t know the answer would help you but I don’t know
Answer:
D
Step-by-step explanation:
10* 8 = 80
15-10=5
8-6=2
5*2= 10
10/2= 5
80+5=85
