x=128/8

x=16

therefore,

room 1 = 1x

           = 1*16=16

room 2 = 3x

            =3*16=48

room 3 = 4x

Step-by-step explanation:

Using Pemdas:

3 (1 + 4) / 3 + 4^2

3 (5) / 3 + 4^2

3 (5) / 3 + 16

15 / 3 + 16

Answer:

A

Step-by-step explanation:

First you have to simplify the equation, you should use PEMDAS. This means you first have to simplify the parenthesis.  simplify it, multiply 3 by 1 and 4. This makes the equation 3+12/3+4^2. Then following PEMDAS, you simplify the exponent. 4^2 is the same as 4x4 so 4^2 is 16. 3+12/3+16, then you can simplify either side first. 3+12/18, then you simplify the only part left. 15/18. The GCM of this fraction is 3 so you divide both sides by 3. 15/3/18/3. Simplify this to get 5/6.

When you simplify equation A, you get 15/3/6. First simplify 15/3 to get 5. This equation answer is 5/6 which is equal to 5/6 so this is the correct answer.

When you simplify equation B, you get 15/3/8. Simplify 15/3 again and get 5. This equation answer is 5/8 which is not equal to 5/6 so this is not the correct answer.

When you simplify equation C, you get 15/3/16. Simplify 15/3 first and get 5. 5/16 is not equal to 5/6 so this is not the correct answer.

Therefore, Equation A is the correct answer.

Perry used the formula V (t) = 24,450(1-0.13)

to find the value of his car t years after he purchased it.

What does 0.13 represent?

A the price of the new car

B the time of year the car was purchased

the value of the car after t years

a 13% decrease in value each year

Answers

Answer:

D) a 13% decrease in value each year

Step-by-step explanation:

Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.

What does 0.13 represent?

The expression given above represents and expression of exponential decrease.

This is represented by the formula

y = a(1 - r)^t

Where

y = Value after time t

a = Initial value

r = Rate of decrease

t = Time

Comparing both expressions

y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t

We can see that:

r = 0.13

This is the rate of decrease.

Converting to Percentage = 0.13 × 100

= 13%

Irene has a spinner with 5 sections, each with a different color. Irene spins the spinner many times, and records the results in the table.

Color: Red Orange Yellow Green Blue
Frequency: 16 11 9 14 10


Find the probability of spinning each color, based on the data. Explain how you calculated each probability.

Answers

Step-by-step explanation:

Probability of spinning a specific colour is the frequency of the colour divided by the total frequency.

Total frequency = 16 + 11 + 9 + 14 + 10 = 60

Hence we have the following probabilities:

P(Red) = 16/60 = 4/15P(Orange) = 11/60P(Yellow) = 9/60 = 3/20P(Green) = 14/60 = 7/30P(Blue) = 10/60 = 1/6
