A model car is built to a scale of 1 in. : 2.5 ft. If the model is 5.8 in. Long how long is the car in real life?

Answers

Answer:

14.5 ft

Step-by-step explanation:

We are told that the model car is built to a scale of 1 in. : 2.5 ft.

That means 1 inches represents 2.5 ft in actual measurement.

Thus, for a 5.8 inch long model, the real life measurement is;

(5.8 inch × 2.5 ft)/1 inch = 14.5 ft

Answers

Answer:

D i believe.

Step-by-step explanation:

Hope this helps :)

The equation with the greatest growth factor is d(t) = 400 . 3^t

Correct option is D.

As per the given data:

Equations representing the number of bacteria in four different dishes as a function of time, t in days, are given.

To find out the equation with the greatest growth factor:

Growth Factor = Term whose power is raised to t.

For option (A), Growth Factor = (5/6) = 0.834

For option (B), Growth Factor = (1/50) = 0.02

For option (C), Growth Factor = (5/2) = 2.5

For option (D), Growth Factor = (3) = 3

Hence, the equation with the greatest growth factor is d(t) = 400 . 3^t

Putting the given values, we get

A set of average city temperatures in December are normally distributed with a mean of 16.3 degrees C and a standard deviation of 2 degrees C.
∘What proportion of temperatures are between 12.9 degrees C and 14.9 degrees C?
you may round your answer four decimal places.

Answers

Answer: 0.1974

Step-by-step explanation:

z1 = (12.9 - 16.3)/2 = (-3.4)/2 = -1.7

Z2 = (14.9 - 16.3)/2 = (-1.4/2) = -0.7

“Z table”

Z1= -1.7 ~ 0.0446

Z2 = -0.7 ~ 0.242

0.2420 - 0.0446= 0.1974

Julie works at a pizza place in Phoenix. She receives a 15% discount on any pizza that she buys. If a large pizza costs $14.00, what is the amount of Julie’s discount? What is the final cost of her pizza?

Answers

Answer:

The final cost of her pizza is $11.90

Step-by-step explanation:

First we need to convert 15% into a decimal, which is 0.15.

Now we multiply $14 and 0.15.

$14 × 0.15 = $2.10.

Now we subtract $2.10 from $14.00.

$14.00 - $2.10 = $11.90
