Shkiper50 [21]

Answer:

David find 8 quarters.

Step-by-step explanation:

Given:

David was in need for some money so he decided to clean out the water fountain at the mall he found 20 nickels and quarters.

The collection of nickels and quarters totaled to 2.6.

Now, to find the quarters David find.

Let the number of nickels be $x$

And the number of quarters be $y$

Thus, the number of nickels and quarters he found:

$x+y=20.$

⇒ $x=20-y$ .........( 1 )

The totaled of nickels and quarters:

$0.05x+0.25y=2.6$

(As 1 nickel=$0.05 and 1 quarter=$0.25)

Now, putting the equation ( 1 ) in the place of $x$ we get:

$0.05(20-y)+0.25y=2.6$

⇒ $1-0.05y+0.25y=2.6$

⇒ $1+0.20y=2.6$

Subtracting both sides by 1 we get:

⇒ $0.20y=1.6$

Dividing both sides by 0.20 we get:

⇒ $y = 8.$

So, the quarters = 8.

Therefore, David find 8 quarters.

Answer:

-8

Step-by-step explanation:

p(x) = - 2x - 3, x ≤ 0 You would use this equation for finding p(0), since 0 is equal to 0.

p(x) = - 2x - 3, x ≤ 0 ← You can ignore the x≤0 part.

p(0) = - 2(0) - 3 Input the value 0 as x.

p(0) = 0 - 3 Simplify

p(0) = -3

Next,

p(x) = -x² - 4, x > 0 You would use this equation for finding p(1), since 1 is greater than 0.

p(x) = -x² - 4, x > 0 ← You can ignore the x>0 part.

p(1) = -(1)² - 4 Input the value 1 as x. 1² is equal to 1 times negative is -1.

p(1) = -1 - 4 Simplify

p(1) = -5

Then,

p(x) = - 2x - 3, x ≤ 0 You would use this equation for finding p(-2), since -2 is less than 0.

p(x) = - 2x - 3, x ≤ 0 ← You can ignore the x ≤ 0 part.

p(-2) = - 2(-2) - 3 Input the value -2 as x. A negative times a negative is

p(-2) = 4 - 3 a positive.

p(-2) = 1 Simplify

Finally, you have to fine the value of $\frac{p(0)+p(1)}{p(-2)}$

$\frac{p(0)+p(1)}{p(-2)}$

$\frac{(-3) + (-5)}{(1)}$ Input the values of p(0), p(1), and p(-2).

$\frac{-8}{1}$ Simplify

-8

The answer is -8.

Compare the two ratios by entering >, < , or = in the box. 1/8 3/20

Elanso [62]

In order to compare the fractions, we need to convert them into decimal form,
1/8 = 0.125
3/20 = 0.15
As 0.15 > 0.125

In short, Your Answer would be 3/20 > 1/8

Hope this helps!
