Fred has a bag of coin with only nickels and quarters. He got $20 by

Sedbober [7]

Answer:

75 quarters 25 nickels

Step-by-step explanation:

q=quarters n=nickels

q+n=100 n=100-q

0.25q +0.05(100-q)=20

From now I will multiply by 100 to avoid decimals

25q + 5(100-q)=2000

20q=1500

q=75 n=25

75*0.25= 18.75

25*0.05=1.25

18.75+1.25=20

**PLEASE HELP ASAP** Terri is analyzing a circle, y^2 + x^2 = 36, and a linear function g(x). Will they intersect?

Alborosie

We analyze the linear function to find that it has equation $y=x$ . Drawing the line, we find that it will intersect the circle at negative and positive x-coordinates.

We can prove this by substituting $y=x$ into the given equation:

$x^2+x^2=36$

$2x^2=36$

$x^2 = 18$

$x = \pm 3\sqrt{2}$

Hence, $x = 3\sqrt{2}$ or $-\sqrt{2}$ , so there are both positive and negative values for $x$ .

Arrange the list of numbers in increasing order.. . 2/5, 4/9, 3/7

Allushta [10]

The numbers given in the question are 2/5, 4/9 and 3/7. We have to take them to decimal form for arranging the numbers in increasing order.
2/5 = 0.40
4/9 = 0.44
3/7 = 0.43
Then, the increasing order of the numbers would be
2/5 < 3/7 < 4/9
I hope the answer has helped you.
