Answer:
- square root of 5 is approximately 1 less than square root of 10
- square root of 10 is between 3.1 and 3.2
- square root of 10 is less than 3.5
Step-by-step explanation:
√5 and √10 are plotted on the number line shown below.
Rounded to 1 decimal place, √5 ≈ 2.2 and √10 ≈ 3.2, so it could be said they differ by about 1 unit. The above answer choices are the ones that match the graph.
Answer:
n = 9
Step-by-step explanation:
20 + 18 + ... + 6 + 4
---------------------------
a = 20 ; d = -2 ; n = ?
--------
4 = 20 + (n-1)(-2)
-16 = (n-1)(-2)
---------
n-1 = 8
n = 9
-------
S(9) = (9/2)(20+4)
S(9) = 4.5*24
S(9) = 108
Answer:
im not sure if sqrt of -27 by it self or over -27 but anyways.
sqrt{-27} = 3i(sqrt)3
sqrt{-37}/(-27) = - i(sqrt)3/9
Answer:
202 tickets for adults were sold and 70 tickets for children are sold.
Step-by-step explanation:
Solve this question using simultaneous linear equation.
•Let the number of tickets sold for adults be a
•Let the number of tickets sold for children be b
The question stated that 272 tickets were sold altogether. So:

Now, make sure that only one of the unknown values remain on the left hand side. For example:

I will refer to the above equation as equation 1.
Now, the question also stated that the tickets sold $1694. This means that:

I will refer to this equation as equation 2.
Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:

Then just solve the equation by finding the value of b.

Lastly, find the value of a. Just take the value of b and then substitute into equation 1.
