Answer:
The number of the cups of uncooked rice is 3 cups
The number of the cups of water is cups
Step-by-step explanation:
* Let us read the recipe of Nasi Gorang
- 2 cups of uncooked rice need cups of water to
make cups of cooked rice
- Joseph needs cups of cooked rice
- We need to know how many cups of uncooked rice Joshep needs
for this recipe and how much water should be added
* We can solve this problem by using the ratio method
⇒ uncooked cups : water cups : cooked cups
⇒ 2 : :
⇒ x : y :
- By using cross multiplication
∵ x ( ) = 2 (
)
∵ =
∵ =
∴ x ( ) = 2 (
)
∴ x = 13
- Divide both sides by
∴ x = 3
∴ The number of the cups of uncooked rice is 3 cups
- By using cross multiplication
∵ y ( ) = (
)(
)
∵ =
∵ =
∵ =
∴ y = (
)(
)
∴ y =
- Divide both sides by
∴ y =
∴ The number of the cups of water is cups
Answer:
m∠2 = 140°
Step-by-step explanation:
m∠1 = m∠3, since they're vertical angles.
Solve for x:
Plug in 6 for x for either m∠1 or m∠3. Doesn't matter since they're equal.
m∠1 = (2(6) + 28)°
m∠1 = (12 + 28)°
m∠1 = 40°
Now that we know m∠1, we can now solve for m∠2.
m∠1 + m∠2 = 180°
40° + m∠2 = 180°
m∠2 = 140°
