A 108-inch pipe is cut into two pieces. One piece is five times the length of the other. Find the lengths of the two pieces.
The short piece is
inches long

Answers

Answer:

18 and 90

Step-by-step explanation:

If we express in units,

Long piece has 5 units

Short piece has 1 unit

total 6 units

108/6 = 18 inch

which is the length of 1 unit

short = 18 * 1

long = 18 *5

A pizza is removed from the oven at a temperature of 425 F. After 15 minutes, the pizza has

cooled to 200°F. Use a continuous exponential decay model to find the approximate decay

rate.


WILL MARK BRAINLIEST!! 20 POINTS!

Answers

Answer:

The decay rate is of 0.05 = 5% per minute.

Step-by-step explanation:

Continuous exponential decay model:

The exponential equation of decay for an amount, after t units of time, is given by:

[tex]A(t) = A(0)e^{-rt}[/tex]

In which A(0) is the initial amount, e(approx 2.72) is the Euler value and r is the decay rate, as a decimal.

A pizza is removed from the oven at a temperature of 425 F.

This means that [tex]A(0) = 425[/tex]

After 15 minutes, the pizza has cooled to 200°F.

This means that [tex]A(15) = 200[/tex], that is, when [tex]t = 15, A(t) = 200[/tex]

We use this to find r.

[tex]A(t) = A(0)e^{-rt}[/tex]

[tex]200 = 425e^{-15r}[/tex]

[tex]e^{-15r} = \frac{200}{425}[/tex]

[tex]\ln{e^{-15r}} = \ln{\frac{200}{425}}[/tex]

[tex]-15r = \ln{\frac{200}{425}}[/tex]

[tex]r = -\frac{\ln{\frac{200}{425}}}{15}[/tex]

[tex]r = 0.05[/tex]

The decay rate is of 0.05 = 5% per minute.

2(19-c)=2(6c+2)+3c
What is this answer (d

Answers

Answer:

2(19-c)=2(6c+2)+3c  use distributive property

38-2c=12c+4+3c      combine like terms

38-2c=15c+4        add 2c on both sides

38=17c+4        subtract 4 from both sides

34=17c         divide by 17 on both sides

2=c and you get 2=c or c=2

Step-by-step explanation:

if brainiest is earned its Greatly Appreciated

The solution to the given equation is c =2.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

2(19 - c) = 2(6c + 2) + 3c

Apply the distributive property

38 - 2c = 12c + 4 + 3c      

Combine like terms in the above equation,

38 - 2c = 15c + 4        

Add 2c on both sides of the equation,

38 = 17c + 4        

Subtract 4 from both sides in the above equation,

34 = 17c        

Divide by 17 on both sides

2 = c or

c = 2

Therefore, the solution to the given equation is c =2.

Answers

Answer: B.

Explanation:
Reflex angle that is more than 180°

175° isn’t more than 180° therefore statement B is not correct.

From the above explanation, the option B statement is not correct.

From the given options we need to identify which statement is not correct.

What is an obtuse angle?

An obtuse angle is any angle greater than 90° and less than 180°.

From option A:

100° angle is an obtuse angle, because which is greater than 90° and less than 180°.

From option B:

175° angle is a reflex angle because it is greater than 180° and less than 360°.

From option C:

Less than 90° lies in I quadrant, more than 90° and less than 180° lies in II quadrant and more than 180° and less than 270° lies in III quadrant.

From option D:

An 85° angle is an acute angle because it is greater than 0° and less than 90°.

From the above explanation, the option B statement is not correct.

6. Describe how we could conduct a simulation to decide whether a simple random sample from this population could produce a sample proportion like 0.55 if, in fact, only 50% of the population supports ban on smoking in cars when young children are present. Each trial represents Number of trials

Answers

Step-by-step explanation:

We have proportion p = 50/100 = 0.50

Probability of success = 1-0.50 = 0.50

To conduct simulation, let's assume experiment is to be done 10 times

1. Use binomial parameters n, number = 10, p = 0.50. we then get the necessary size of population To carry out the sampling.

2. We get a random sample and get the size of people who support an against smoking with kids in the car.

3. We repeat this process after drawing sample and also get the number of those in support of ban.

4. After getting n, we find proportion.
