y=7.5x

because if every 2 you go up by 15, 1 is 7.5 for your slope.

The area of the smallest equilateral triangle with one vertex on each of the sides of the right triangle with side lengths and <

Gre4nikov [31]

Set up the given triangle on x-y coordinates with right angle at (0,0). So the two vertices are at (5,0) and (0,2 $sqrt{x} n]{3}$ )

let (a,0) and (0,b) be two vertices of the<span> equilateral triangle. So the third vertex must be at </span> $(\frac{a+\sqrt{3}b}{2} , \frac{b+\sqrt{3}a}{2} )$

for a pt (x,y) on line sx+ty=1, the minimum of $\sqrt{x^{2} + {y^{2} }$
equals to $\frac{1}{ \sqrt{ s^{2} + t^{2} } }$

smallest value happens at $\frac{10 \sqrt{3} }{67}$

so area is $\frac{75\sqrt{3}}{67}$

hence m=75, n=67, p=3
m+n+p = 75+67+3 = 145

Amy needs to mail a gift card to a friend. She uses 47-cent stamps and 6-cent stamps to pay $2.42 in postage. How many of each s

AVprozaik [17]

Answer:

Answer:Amy used 4 41-cent stamps and 8 6-cent stamps.

Step-by-step explanation:

Let x represent the number of 41-cent stamps that Amy used. Let y represent the number of 6-cent stamps that Amy used.

41 cents = 41/100 = $0.41

6 cents = 6/100 = $0.06

She uses 41-cent stamps and 6-cent stamps to pay $2.12 in postage. It means that

0.41x + 0.06y = 2.12

Multiplying through by 100, it becomes

41x + 6y = 212

6y = 212 -41x

We would test for corresponding values of x and y that satisfies the equation and they must be whole numbers.

If x = 3,

6y = 212 - 41 × 3 = 89

y = 89/6 = 14.8333

If x = 4,

6y = 212 - 41 × 4 = 48

y = 48/6 = 8

y = 48/6 = 8
