The value (in cents) of the change in a purse that contains twice as many nickels as pennies, five more dimes than nickels, and

nexus9112 [7]

Value of the pursue in cents: $131p+175$

Step-by-step explanation:

Let's call:

$p$ = number of pennies

The problem tells us that the pursue contains twice as many nickels as pennies, so the number of nickels is

$n=2p$

Also, the pursue contains five more dimes than nickels, so the number of dimes is

$d=n+5=2p+5$

And finally, the pursue contains as many quarters as dimes and nickels combained, so the number of quarters is

$q=d+n=(2p+5)+2p=4p+5$

The value of each type of coin is:

Penny: 1 cent

Nickel: 5 cents

Dime: 10 cents

Quarter: 25 cents

So, the total value of the pursue in cents is:

$1p+5n+10d+25q$

And substituting,

$=p+5(2p)+10(2p+5)+25(4p+5)=\\p+10p+20p+50+100p+125=\\131p+175$

So, this is the value of the change in the pursue in cents.

What is the perimeter of the triangle?

Dmitrij [34]

Answer:

19.24 cm

Step-by-step explanation:

Square the outsides of the triangle. 8 squared is 64 and 5 squared is 25.

A^2+B^2=C^2

c^2 is always the diagonal line.

a^2=25

c^2=64

Subtract 25 from 64 to find b^2

64-25= 39

Add all three together to get your perimeter.

The square root of 64 is 8, the square root of 25 is 5 and the square root of 39 is 6.24. Add 8, 5 and 6.24 together and you get the perimeter.

5+8+6.24= 19.24

HELP PLEASE!!!! THERE R 3 QUESTIONS. MAKE SURE TO ANSWER ALL 3!!! TYSM

sergeinik [125]

Answer:
1. k=2
2. b=2f
3. 68

Explanation

1. y=kx (replace x&y with 2 values)

12=k(6) (isolate k)
/6 /6

2=k *check with another value to see if k truly is 2

2. since the constant of variation is 2, we can see that 2x the number of flowers make up the birds. so...

b(birds/y-value)=2(constant)f(number of flowers)

b=2f

3. input 34 into f, since there are 34 flowers

b=2*34 (use mental math)

b=68
in other words, there will be 68 birds.

If two variables were completely correlated, their correlation coefficient would be:

meriva

Pearson's correlation coefficient 'r' measures the degree to which two variables are correlated. The value is between -1 and 1. Negative values correspond to negative correlation (as one variable increases, the other variable decreases) whereas positive values correspond to positive correlation. The larger the absolute value of r, the closer a correlation graph resembles a set of points on the same line. Therefore, if two variables are completely correlated, the correlation value is 1 or -1, depending on whether the correlation is positive or negative.
