andrew-mc [135]

Answer:

The total number of students that ate lunch are 300 .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

There are 4 lunch choices in a school cafeteria: Salad, Pizza, Spaghetti, and Sub Sandwiches.

The percentage of students that chose salad is 15%.

If 45 students chose salad.

Here

Percentage = 15%

Part value = 45

15 = \frac{45\times 100}{Total\ value}

Total\ value= \frac{4500}{15}

Total\ value= 300

Therefore  the total number of students that ate lunch are 300 .

Suppose that ∠BNR and ∠RNA are adjacent angles where m∠BNR=12w-19,
wariber [46]

Answer:

Step-by-step explanation:

Sum of interior adjacent angle is 180 degrees.

Given  

m∠BNR=12w-19,

m∠RNA= ¼(w+199)

m∠BNA=2(12w-19).

Substitute

m∠BNR+m∠RNA=

¼(w+199)+12w-19, = 2(12w-19).

W+796+48W-76 = 96W-152

49W-96W = -152+76-796

-47W = 872

W = 872/47

W = 18.55
