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

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

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

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

What is $2.75 in cents

Answers

275 cents
100 times 2 is 200
200 plus 75 is 275
So it’s 275 cents

To convert dollar into cents, we need to multiply by 100. Thus, the total amount is equivalent to 275 cents.

Given:

Given amount is $ 2.75.

According to question, we have to convert currency of dollar into cents.

Conversion of amount from dollar to cent can be done as,

[tex]1\;\$=100\;\rm{cents}\\ \$\;2.75=\$\;\frac{275}{100}\\=\frac{275}{100}\times 100\;\rm{cents}\\=275\;\rm{cents}[/tex]

Therefore, the total amount in cents is 275 cents.

Alright, archtan /

tan

−

(

)

is the inverse of tangent. Tan is

sin

cos

. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.

Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.

Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.

Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.
