Geometry questionnn!

Musya8 [376]

Answer:

88 units

Step-by-step explanation:

$In\: \triangle OBR \:\&\: \triangle OWN$

BR || WN (Given)

Therefore,

$\angle OBR \cong \angle OWN$ (Alternate angles)

$\angle BOR \cong \angle WON$ (Vertical angles)

$\therefore \triangle OBR \sim \triangle OWN$ (AA postulate)

$\therefore \frac{OR}{ON} =\frac{BR}{WN}$ (csst)

$\therefore \frac{OR}{56} =\frac{24}{42}$

$\therefore \frac{OR}{56} =\frac{4}{7}$

$\therefore OR =\frac{4\times 56}{7}$

$\therefore OR ={4\times 8}$

$\therefore OR =32$

RN = OR + ON

RN = 32 + 56

RN = 88 units

The answer si:
- 16 servings - 6 oz of salmon
- 24 servings - 9 oz of salmon
- 80 servings - 30 oz of salmon
- 100 servings - 37.5 oz of salmon

1 roll is 8 servings and it is also made of 3oz of smoked salmon. That means that 3oz of smoked salmon is needed fo 8 servings.
Now, let's made some proportions:

16 servings:
3 oz is for 8 servings, how much oz is for 16 servings:
3 : 8 = x : 16
x = 3 · 16 ÷ 8 = 6 oz

24 servings:
3 oz is for 8 servings, how much oz is for 24 servings:
3 : 8 = x : 24
x = 3 · 24 ÷ 8 = 9 oz

80 servings:
3 oz is for 8 servings, how much oz is for 80 servings:
3 : 8 = x : 80
x = 3 · 80 ÷ 8 = 30 oz

100 servings:
3 oz is for 8 servings, how much oz is for 100 servings:
3 : 8 = x : 100
x = 3 · 100 ÷ 8 = 37.5 oz
