150% of 66(Need the work shown)

Answers

Answer 1
Answer: Change 150% into a decimal by multiplying it by 100.
150(100)= 1.50
Now multiply 1.50(66)= 99
Answer 2
Answer: 66 is the 100%
we can solve this problem by the rule of three.

Therefore:
66------------------------100%
x--------------------------150%

x=(66 * 150%) / 100%=99

Answer 150% of 66 is 99.

Other method:
150% of 66=1.5 *66=99

Dr. Six drives through two stoplights on her way to work. The first light is green for 20 seconds out of each minute. The second light is green for 35 seconds out of each minute. What is the probability that Dr. Six will hit two green lights?

Answers

Probability 1 * Probability 2 = Probability of both

Let minute = 60 seconds

First light probability = 20/60 (20 seconds out of each 60 seconds)
= 0.33 (recurring)

Second light probability = 35/60 (35 seconds out of each 60 seconds)
= 0.5833 (recurring)

To get a more accurate end probability use the numbers 
20/60 and 35/60 appose to the rounding (on the calculator):

Using the formula at the top:
20/60 * 35/60 = 0.194  (3 DP) 

The probability of that Dr. Six will hit two green lights is 0.194 (3DP)





The quadratic function below represents a parabola that opens down. Which value could be the missing number in the equation ? The missing coefficient could be ?

Answers

Answer:

-4

Step-by-step explanation:

The direction of the parabola depends on the sign of the leading coefficient i.e. sign of the coefficient with the squared term.

Remember these two points for vertical parabola:

  • If the leading coefficient is positive the parabola will always open upwards
  • If the leading coefficient is negative the parabola will always open downwards

We are given that the parabola opens down. This means that the leading coefficient must be negative. Among the given options only one option contains a negative number i.e. -4.

Therefore, the missing coefficient could be -4
