Answer:
4 CUPS OF SUNFLOWER SEEDS for the larger batch
Step-by-step explanation:
From the small batch:
2 cups of peanuts= 1 cup of sunflower seeds
Since the ratios are thesame, it therefore means that the proportion will be thesame.
For the large batch:
8 cups of peanuts = X cups of sunflower seeds.
Mathematically, let's express it as:
Let p = cups of peanuts
S= cups of sunflower seeds
X = unknown number of sunflower seeds
Therefore, connecting equation is:
2P = 1S
8P = X's
Cross Multiply to solve for X
X's * 2P = 1S * 8P
2PX = 8P
X = 8P / 2P
It therefore means that there'll be a need of:
4 CUPS OF SUNFLOWER SEEDS for the larger batch
Answer:
Step-by-step explanation:
- Let the speed of the boat = b and the speed of the current = c
<u>Equations to reflect time, time = distance/speed:</u>
- 80/(b + c)= 5 ⇒ b - c = 80/5 ⇒ b + c = 16
- 80/(b - c) = 10 ⇒ b - c = 80/10 ⇒ b - c = 8
<u>Sum of the 2 equations above</u>
- b + c + b - c = 16 + 8
- 2b = 24
- b = 12
- c = 16 - 12 = 4
So the speed of the boat is 12 mph
The speed of the current is 4 mph
