Answer:
B.70
Step-by-step explanation:
For one or two angles are complementary angle(s), they have to equal 90°.
So, we need to find the larger angle, but what about the other?
Let x be the other angle and y be the angle we are looking for
x + y = 90
Lets look for x first, since one angle is ten less than four times the angle we are looking for or visa versa, we must:
y = 4x - 10
For an exchange, lets take out the y variable for another x variable:
So now we should have x + 4x - 10 = 90
Combine like terms and do cross equation :
x + 4x -10 = 90
5x - 10 = 90
Add 10 to both sides:
5x = 100
100/5 = 20
So <u><em>x=20</em></u>
<u><em></em></u>
Now for y which is what we are looking for,
y = 4x - 10
Since x is 20, plug it in
y = 80 - 10
y=70 is our larger angle
Answer:
Step-by-step explanation:
Yes!
The square root of a number represents the "middle number" possible as a divisor of any given number.
All other factors will have one number above the square root and one number below the square root.
For example consider 80.
The prime factors are 2 * 2 * 2 * 2 * 5. The square root of 80 is about 9, so any factor of 80 must have all the primes under the square root or 1 above and 1 below.
10 * 8 is one such pair. 10 is above 9 and 8 is below it.
=============
I have read the comments made by others. I believe what they are saying is true, but I'm not interpreting the question the same way. I'm looking at these as pairs. The commenter is taking 1 prime at a time. It's a fair way to look at the question. You have to decide how you want to present your answer. You could go either way. That's the problem with some of these questions.
Answer:
The right answer for the question that is being asked and shown above is that: " B. Accounts Receivable for $500." Sue’s Jewelry sold 20 necklaces for $25 each to a credit customer. The invoice included a 6% sales tax and payment terms of 2/10, n/30. Five necklaces were returned prior to payment. The entry to record the original sale would include a debit to accounts Receivable for $500.
"Accounts Receivable for $530. B. Accounts Receivable for $500. C. Sales for $530. D. Sales for $500."
I think you missing this in your question but this is the answer
The sum of the measures of the angles in a triangle is always 180 degrees.
If you follow the procedure in the question, you will have a straight angle when you put the pieces together. All straight angles have 180 degrees. Therefore, there are 180 degrees in every triangle.
