You are hiking on a trail that leads down from the top of a mountain. At 1 P.M. you are at an elevation of 6000 feet. At 5 P.M.

Hitman42 [59]

Okay to start this out. You started hiking at 1 P.M. You are at an elevation of 6000 ft. At 5 PM You are at an elevation of 4800 feet. 6000 feet - 4800 feet = 1200 feet in 4 hours.
Make a ratio 4(Hr):1200 Ft
3(Hr):900 Ft
2(Hr):600 Ft
1(Hr):300 Ft
So at the end of the equation your hourly change is -300 ft, because the elevation is going down.

Find the vertices of the image after the given transformation (x,y)—> (2x, 1/3y)

Olin [163]

Answer:

see explanation

Step-by-step explanation:

the translation rule (x, y ) → (2x, $\frac{1}{3}$ y )

means multiply the x- coordinate by 2 and multiply the y- coordinate by $\frac{1}{3}$ ), so

A (- 1, - 3 ) → A' (- 2, - 1 )

B (4, - 3 ) → B' (8, - 1 )

C (4, 3 ) → C' (8, 1 )

D (- 1, 3 ) → D' (- 2, 1 )

Hannah has some pennies and some nickels. She has a maximum of 25 coins worth a minimum of $0.65 combined. If Hannah has 11 nick

kotykmax [81]

Answer:

Minimum number of pennies = 10

Step-by-step explanation:

Given:

Maximum number of coins Hannah have = 25

Total number of of nickels (coins) she has = 11

Total value of the combined coins = $ 0.65

We have to find the minimum number of pennies.

Let the number of pennies be "p" and no. of nickels be "n".

Note:

Value of 1 penny = $ 0.01

Value of 1 nickel = $ 0.05

Arranging the above situation in terms of equations:

According to their quantities.

⇒ $n+p\leq 25$ and $11+p\leq 25$ so $p\leq 14$

According to their values.

⇒ $0.05(n)+0.01(p)\leq \$\ 0.65$

⇒ $0.05(11)+0.01(p)\leq \$\ 0.65$

⇒ $\$\ 0.55+0.01(p)\leq \$\ 0.65$

⇒ $0.01(p)\leq \$\ 0.65-\$\ 0.55$

⇒ $0.01(p)\leq \$\ 0.10$

⇒ $(p)\leq\frac{ \$\ 0.10}{0.01}$

⇒ $(p)\leq 10$

Minimum number of pennies :

⇒ $(p)\leq 10$ which also satisfies $p\leq 14$

Therefore :

⇒ $p=10$

Plugging p= 10 we can verify the values.

⇒ $0.05(11)+0.01(10)\leq \$\ 0.65$

⇒ $0.55+0.10\leq \$\ 0.65$

⇒ $\$\ 0.65\leq \$\ 0.65$

So,

Minimum number of pennies Hannah have = 10
