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

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

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

$20y=310-110$

$20y=200$

$y=10\ quarter$

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

Can the sides of a triangle have lengths 2, 5, and 5?

oksian1 [2.3K]

Answer:

No, the sides of a triangle cannot have the lengths 2, 5, and 5.

Step-by-step explanation:

Using the right triangle formula, aka. the Pythagorean Theorem, which is $a^{2}+b^{2}=c^{2}$ we need to substitute the sides given with the variables.

$2^{2} +5^{2} =5^{2}$

Simply to $4+25=25$ .

Add 4 to 25.
