Hannah has $3.10 in her piggy bank in nickels and quarters. If there are 22 coins in her piggy bank, how many are nickels and ho

PIT_PIT [208]

Answer:

$12\ nickel$

$10\ quarter$

Step-by-step explanation:

we know that

$1\ nickel=\$0.05$

$1\ quarter=\$0.25$

Let

x------> the number of nickel coins

y-----> the number of quarter coins

we know that

$x+y=22$

$x=22-y$ -----> equation A

$0.05x+0.25y=3.10$ ----> multiply by 100 both sides

$5x+25y=310$ -----> equation B

Substitute equation A in equation B and solve for y

$5(22-y)+25y=310$

$110y-5y+25y=310$

$20y=310-110$

$20y=200$

$y=10\ quarter$

$x=22-y$ ------> $x=22-10=12\ nickel$

Answer:

x = 9
y = 45
z = 9 root 2

Step-by-step explanation:

In this isosceles right triangle, the acute angles are equal and the side lengths have the ratios 1 : 1 : √2

y° = 90° -45° = 45°

9 : x : z = 1 : 1 : √2 = 9 : 9 : 9√2

x = 9; z = 9√2
