Answer: 75%
Step-by-step explanation:
Only 9 students have taken fewer than 21 courses
9/12 = 0.75 or 75%
Answer:
upward
Step-by-step explanation:
y=4x²+4
Look at the coefficient of x²
If it is positive, it opens upward, IF it is negative, it opens downward.
In this case, the x² coefficient is +4, hence it opens upward
(see attached for plot)
To find the answer to this problem, all you have to do is divide the price of the product by the number of ounces. So to find the price per ounce of the large can of tomato soup, you divide 4.40 by 22, which equals .20 cents per ounce. For the smaller can, you divide 1.80 by 10, which equals .18 cents per ounce. So the smaller can has the best price per ounce.
Answer:
angle 1
Step-by-step explanation:
Using the trigonometric mnemonic SOH CAH TOA, we know that cos or cosine is the ratio between the adjacent side and hypotenuse side.
This means that if cos A = 0.48, A is the measure of the angle which it's relative adjacent side divided by the hypotenuse of the triangle will be around 0.48.
Let's try angle 2, cos (angle 2) = adjacent / hypotenuse = 7.8 / 8.9 = 0.876404494382 ≈ 0.87 ≠ 0.48. Since the proportions are not equal, this angle cannot be the one marked as A.
Since angle 3 is a right angle, the adjacent could be either side so it cannot be correct. Thus angle 1 is correct.
