Answer:
the scale factor is 2
Step-by-step explanation:
Step 1: Set up the proportion
4/12 = 10/x
Step 2: Cross multiply to get
120 = 4x
Step 3: Divide all by 4 to get
30 = x
Answer: So in total, 10 students would spend $30 on lunch!
Answer:
Step-by-step explanation:
x^2-8x+12=(x-2)(x-6)
Using the formula for interest:
F = P (1 + r/n)^t
Where:
F = future value
P = Principal value
r = interest rate per year
n = interest period
t = duration
Substituting the given values:
F = 200 (1 + 0.32/12)^1
F = 205.33
To obtain the interest, we subtract the principal value from the future value. This is shown below:
Interest = 205.33 - 200 = 5.33
Among the choices, the answer is A.
