Answer:
add the decimals thats all
Step-by-step explanation:
Answer:
You would do this problem like a normal varible problem. x=10
Step-by-step explanation:
Since 9x is a right angle the inside would also be 9x
9x+4x+10+40=180
180 because that is how much a triangle equals
combine like terms
13x+50=180
subtract 50 from both sides
13x=130
divide by 13
x=10

Answer: 15 / 86
Step-by-step explanation:
First find out the total number of customers at Deion's boutique:
= 15 + 71
= 86 customers
Out of this 86, 15 customers wore a small size.
The odds of picking one of those 15 is:
= 15 / 86
I think it would be 19.2% if you rounded it would be 19%
Answer:
n = 2 + 2√3 and n = 2 - 2√3
Step-by-step explanation:
Let the number be n.
Then n² + 1 = 4n.
Rearranging this in proper quadratic format:
n² - 4n + 1
Here the coefficients are a = 1, b = -4 and c = 1.
Then the discriminant is b²-4ac, or (-4)²-4(1)(1) ), or 16 - 4, or 12.
By applying the quadratic formula, we find that the roots are:
- (-4) ± √12
n = ------------------
2
or n = 2 + 2√3 and n = 2 - 2√3
