Answer:
-500/11
Step-by-step explanation:
0.22 in fraction is 11/50
After replacing the decimal with a fraction, subtract it from -10.
You'll have -10÷(11/50)
You'll then change the division sign to a multiplication sign.
You'll then have that -10 × 50/11
-10×50 = -500/11.
F(x) = x² - 13x + 30
f(x) = x² - 3x - 10x + 30 = 0
f(x) = x(x - 3) -10(x - 3) = 0
f(x) = (x-3)(x-10) = 0
f(x) = 3 OR 10
In short, Your Answer would be Option B & D
Hope this helps!

Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:

First, use the co-function identity:

We can turn the second term into cosine:

Substitute:

Now, use the sum to product formulas. We will use the following:

Substitute:

Use the even-odd identity:

Therefore:

Replace the second term with the original term:

Proof complete.
You would take the number of ice cream cups which is 12 and divide it by the cost which is 9.60
12/9.60=1.25
