Sam has $2.25 in quarters and dimes, and the total number of coins is 12. How many quarters and how many dimes?

a_sh-v [17]

N₁*$0.10 + n₂*$0.25 = $2.25

n₁ + n₂ = 12

-----------

This means that:

n₁ = 12 - n₂

And:

(12 - n₂)*$0.10 + n₂*$0.25 = $2.25

12*$0.10 - n₂*$0.10 + n₂*$0.25 = $2.25

$1.20 + n₂*$0.05*(5-2) = $2.25

$1.20 + n₂*$0.05*3 = $2.25

$1.20 + n₂*$0.15 = $2.25

n₂*$0.15 = $2.25 - $1.20

n₂*$0.15 = $1.05

n₂ = ($1.05)/($0.15)

n₂ = 7

If n₂ = 7:

n₁ + 7 = 12

Therefore, n₁ = 5.

---------

Answer:

5 dimes and 7 quarters.

Show that the two triangles ABC and DEF are congruent by the<br> HL theorem.

inna [77]

Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.

The Hypotenuse-Leg theorem states that two <em>right</em> triangles are <em>congruent</em> if and only if their hypotenuses and any of their <em>corresponding</em> legs are <em>congruent</em>. That is to say:

$\overline {AC} \cong \overline {DF}$ , $\overline{BC} \cong \overline {EF}$

$AC = DF, BC = EF$

$\sqrt{AB^{2}+BC^{2}} = \sqrt{DE^{2}+EF^{2}}$ , $BC = EF$

If we know that $AB = 10$ , $BC = 4$ , $DE = 10$ and $EF = 4$ , then we have the following outcomes:

$\sqrt{10^{2}+4^{2}} = \sqrt{10^{2}+4^{2}}$

$4 = 4$

Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.

a jumbo jet carries 330 passengers, 32 in first class, and the remainder in coach. if the average first class ticker is $860 and

Sholpan [36]

330-32 = 298

32 * 860 = 27,520

298 * 360 = 107,280

107,280 + 27,520 = $134,800 total
