Jason has $2.25 worth of dimes and quarters he has twice as many dimes as quarters determine the number of dimes and the number

of quarters that jason has
Mathematics

Answer: jason has 10 dimes and 5 quarters.

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a quarter is 25 cents. Converting to dollars, it becomes

25/100 = $0.25

Let x represent the number of dimes that he has.

Let y represent the number of quarters that he has.

He has twice as many dimes as quarters. This means that

x = 2y

Jason has $2.25 worth of dimes and quarters. This means that

0.1x + 0.25y = 2.25 - - - - - - - - - - - 1

Substituting x = 2y into equation 1, it becomes

0.1 × 2y + 0.25y = 2.25

0.2y + 0.25y = 2.25

0.45y = 2.25

y = 2.25/0.45

y = 5

x = 2y = 2 × 5

x = 10

A chemist examines 12 sedimentary samples for bromide concentraction. The mean bromide concentration for the sample date is 0.43
Umnica [9.8K]

Answer:

a) z = 1.645

b) Lower endpoint: 0.422cc/m³

Upper endpoint: 0.452 cc/m³

Step-by-step explanation:

Population is approximately normal, so we can find the normal confidence interval.

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645. This is the critical value, the answer for a).

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.645*\frac{0.0325}{\sqrt{12}} = 0.015

The lower end of the interval is the sample mean subtracted by M. So it is 0.437 - 0.015 = 0.422cc/m³.

The upper end of the interval is the sample mean added to M. So it is 0.437 + 0.015 = 0.452 cc/m³.

b)

Lower endpoint: 0.422cc/m³

Upper endpoint: 0.452 cc/m³

Kate sold 12 of her paintings and purchased 7 more. if kate has 21 paintings now, how many paintings did she have to begin with?
kicyunya [14]
First, let x or any variable represent the number of paintings Kate initially has. After selling 12 of it, her paintings now becomes only x - 12. Then, she purchased 7 more making the number of her paintings become x - 12 + 7 = x - 5. This number tantamount to 21. 

                                           x - 5 = 21      ; x = 26

Thus, Kate initially had 26 paintings.

PLSS HELP ME!!!<br><br><br>question <br><br>3x - 4/5= - 1/2<br><br>what is the value of x?​
Minchanka [31]

Answer:

x = \frac{1}{10}

Step-by-step explanation:

Given

3x - \frac{4}{5} = - \frac{1}{2}

Multiply through by 10, the lcm of 5 and 2 to clear the fractions

30x - 8 = - 5 ( add 8 to both sides )

30x = 3 ( divide both sides by 30 )

x = \frac{3}{30} = \frac{1}{10}
