Answer:
Commission earned= $43.95
Step-by-step explanation:
Giving the following information:
Commission rate= 15% = 0.15
Sales= $293
<u>To calculate the commission earned by selling the laptop, we need to use the following formula:</u>
Commission earned= commission rate*sales
Commission earned= 0.15*293
Commission earned= $43.95
Discriminant = b^2 - 4ac, where a, b and c come from the form of the quadratic equation as ax^2 + bx + c
Discriminant = (4)^2 - 4(1)(5)
= 16 - 20
= -4
-4 < 0, therefor there are no roots
(If the discriminant = 0, then there is one root
If the discriminant > 0, there are two roots, and if it is a perfect square (eg. 4, 9, 16, etc.) then there are two rational roots
If the discriminant < 0, there are no roots)
For how many books he got : 4
This is but adding up 3 of $3.95 to get the total of $11.85
You then want to subtract that from $47.65 to get $34.80
You subtract that by the $8.95 4 times so you see he bought 4 books
After you talk about how many books did he buy after that sentence I’m not sure what your saying
Answer:
a = sqrt(2)
Step-by-step explanation:
This is a right triangle so we can use trig functions
sin theta = opp / hyp
sin 30 = a / 2 sqrt(2)
2 sqrt(2) sin 30= a
2 sqrt(2) * 1/2 =a
sqrt(2) =a
45 + 35x = 40x
45 = 40x - 35x
45 = 5x
45/5 = x
9 = x <=== they are the same cost at 9 nights
