Leo is looking at two different savings plans. The first plan requires an initial deposit of $500 and grows at an annual interes
aksik [14]

Answer:

3rd Option and 4th Option

Step-by-step explanation:

Note: The options to the question is attached as picture below

<u>1st case</u>

Initial deposit (P) = 500

Annual interest rare (r) = 2.5%

Account balance after x years, y = P(1+r/100)×

y = 500(1+2.5/100)×

y = 500(1+0.025)×

y = 500(1.025)× ----- 3rd option

<u>2nd case</u>

Initial deposit (P) = 400

Annual interest rare (r) = 2%

Account balance after x years, y = P(1+r/100)×

y = 400(1+2/100)×

y = 400(1+0.02)×

y = 400(1.02)× ---- 4th option

When traveling with the current, it takes Kamal 1 hour to travel 12 miles on a boat. It takes the boat 1.5 hours to travel the s
Sergeu [11.5K]

Answer:

the rate / speed of the boat is 10 miles per hour.

the rate / speed of the current is 2 miles per hour.

Step-by-step explanation:

r = rate of boat (speed of boat)

t = time

d = distance.

c = rate of current (speed of current)

with the current, the formula becomes (r + c) * t = d

against the current, the formula becomes (r - c) * t = d

going with the current, the boat takes 1 hour to travel 12 miles.

therefore:

(r + c) * t = d becomes (r + c) * 1 = 12

going against the current, the boat takes 1.5 hour to travel the same 12 miles.

therefore:

(r - c) * t = d becomes (r - c) * 1.5 = 12.

your two equations that need to be solved simultancously are:

(r + c) * 1 = 12

(r - c) * 1.5 = 12

divide both sides of the second equation by 1.5 and leave the first equaion as is to get:

 

r + c = 12

r - c = 8

add the equations together to get:

2 * r = 20

solve for r to get:

r = 20 / 2 = 10

(r + c) * 1 = 12 becomes (10 + c) * 1 = 12

simplify to get 10 + c = 12

solve for c to get c = 12 - 10 = 2

(r - c) * 1 = 8 becomes (10 - c) * 1 = 8

simplify to get 10 - c = 8

solve for c to get c = 10 - 8 = 2

you have:

r = 10

c = 2

that's your solution.

the rate / speed of the boat is 10 miles per hour.

the rate / speed of the current is 2 miles per hour.

The elevation of Mt.Everest is 29,028 feet. The elevation of the Dead Sea is -485 feet. What is the difference in the elevation
Dvinal [7]

The difference in the elevation between Mt.Everest and the Dead Sea is 29513 feet

<h3><u>Solution:</u></h3>

Given that,

Elevation of Mt.Everest = 29028 feet

Elevation of the Dead Sea = -485 feet

To find: difference in the elevation between Mt.Everest and the Dead Sea

Therefore,

Difference = Elevation of Mt.Everest - Elevation of the Dead Sea

Substituting the given values, we get

Difference = 29028 - ( - 485)

Difference = 29028 + 485 = 29513

Thus the difference in the elevation between Mt.Everest and the Dead Sea is 29513 feet
