A punch recipe calls for orange juice and pop in the ratio of 2:5 the recipe requires 1L of Pop to serve 7 people a) how much orange juice is needed for 7 people?
b)about how much orange juice and pop do you need to serve 15 people? 20 people?
plz say how you answered this

Answers

Answer 1
Answer:

O : P => 2 : 5

(a)    1 liter of pop to serve 7 people

=>           5 units = 1

               1 unit = 1 / 5

Orange juice => 2 units

Hence, Orange juice needed is 2 * 1 / 5 = 0.4 liters

 

(b)    If 1 liter of pop is needed to serve 7 people, then we will need (1 / 7) * 15 for 15 people

i.e. 2.14 liters

 

As the ratio of O : P = 2 : 5,

               5 units = 2.14

               1 units = 2.14 / 5

 

For Orange juice, we will need 2 * 2.14 / 5 = 0.856 liters for 15 people

What is Pythagoras theorem?

The Pythagoras theorem which is also referred to as the Pythagoreantheorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Let the length of the rope be x.

Now, x²=53²+28²

⇒x²=2,809+784

⇒x=59.94≈60

Therefore, the length of the rope is 60 feet.

So Pythagorean theorem, I assume.
remember: a^(2) + b^(2) = c^(2)
The a and b seems to be 53 and 28 (the order doesn't really matter)
so, 53^(2) + 28^(2) = c^(2)
OR \sqrt{53^(2) + 28^(2) } = c

Calculator time! 
√(2809 + 784)
√(3593) = c
59.94 ≈ c
Therefore, the rope is approximately 59.94 feet long.

As the train’s engineer, Erin guided the train on a 64 mi run, which took 1.7 h. She then stopped on a side rail to let a second train pass. She then continued another 80 mi, which took 1.9 h.What was the train’s average speed for the entire run?

Answers

(144 miles)/(3.6 hours)= 40 (m)/(h)Let's calculate how many miles the train has passed in total:
64+80=144 miles

let's also calculate the complete time: (we can ignore the waiting time here, since they also didn't move during this time:

1.7h+1.9h=3.6 hours.

And now we only need to divide the distance per time:

So the correct answer is 40 miles per hour!
