An element with mass 640 grams decays by 7.3% per minute. How much of the element is remaining after 8 minutes to the nearest 10th of a gram?

Answers

9514 1404 393

Answer:

  349.0 grams

Step-by-step explanation:

The amount remaining can be modeled by an exponential function of the form ...

  remaining = (initial amount)(1 - decay rate)^t

  q(t) = 640(1 -0.073)^t

  q(8) = 640(0.927^8) ≈ 349.0 . . . grams

The amount remaining after 8 minutes is about 349.0 grams.

|10-4x|-2=9
Please help

Answers

I'm assuming you're asking for x.

Answer: -1/4 and 21/4

Step 1: Add 2 to both sides of the equation.

∣10−4x∣=9+2

Step 2: You can get two equations from this.

10−4x=11  and -(10-4x)=11−(10−4x)=11

Solve both equations.

1st equation:

−4x=11−10

−4x=1

x=-1/4

2nd equation:

−10+4x=11

4x−10=11

4x=11+10

4x=21

x=21/4

Answer:

[tex]x=-\frac{1}{4} , \frac{21}{4}[/tex]

Step-by-step explanation:

Isolate the absolute value signs by adding 2 to both sides of the equation.

[tex]|10-4x|=11[/tex]

Create a positive and negative case to solve for absolute value problems.

[tex]10-4x=11 \\ 10-4x=-11[/tex]

Subtract 10 from both sides of both equations.

[tex]-4x=1 \\ -4x=-21[/tex]

Divide both sides of each equation by -4 in order to isolate and solve for x.

[tex]x=\frac{1}{-4} \\ x= \frac{-21}{-4}[/tex]

Simplify these x-values by canceling out the negative sign (2 negatives = 1 positive).

[tex]x= -\frac{1}{4} \\ x = \frac{21}{4}[/tex]

x = -1/4 and 21/4 are the solutions to this equation.

Exercise 18.14. Toy defects. Workers at a factory produce a toy with a defect about once every 4 hours on average. Each toy costs the factory approximately $7 in labor and supplies. a. What is the expected number of toys with defects at the end of a 40-hour work week

Answers

Answer: $70

Step-by-step explanation:

Given that:

Toy with defect is produced once every 4 hours

Cost of labor and supplies incurred for producing a defective toy = $7

Number of defective toys that is expected to be produced in a 40 hour work week :

Number of hours / average hour for producing 1 defective toy

= 40/ 4

= 10 defective toys

Cost incurred for producing 10 defective toys :

($7 * 10) = $70

Xavier is solving a problem on the whiteboard as shown.
Part A. Is Xavier's solution correct? If not, identify where he made an error.
Part B. Solve 7950 divided by 25.

Answers

Let us see how we can solve this step by step each :

6417 ÷ 31 , we divide 64 by 31 and get the resulting quotient as 2 .

Then we bring down 1 . So , the number below is 21 , which cannot be divided by 31 .

So , we will have to bring down 7 for which we have to add a 0 to the quotient . Then the quotient will become 20 as of now .

As 217 is divisible by 3 , I put seven near 21 , making the quotient as 217 and get the remainder 0 .

Hence in the correct solution the correct quotient = 207 .

In Xavier's solution :

But the same thing has not been done in Xavier's solution as he has put a 0 after 7 instead of putting it before 7 . Hence , Xavier's mistake is that he put the 0 after 7 instead of putting it before 7 .

In Xavier's solution the quotient is = 270

Therefore , Xavier's mistake is that he put the 0 after 7 instead of putting it before 7 .
