densk [106]

Answer:

The fraction that eats in the cafeteria is 2/3

Step-by-step explanation:

To find this, start by taking the number of students and subtracting the amount that bring their lunch.

18 - 6 = 12 that eat in the cafeteria.

Now that we have that number, divide by the total number of students.

12/18

A kite has A = 120 cm2 and d1 = 16 cm. Identify the length of d2.​
neonofarm [45]

Answer:

d₂ = 15 cm

Step-by-step explanation:

The area (A) of a kite is calculated as

A = \frac{1}{2} d₁d₂

Here A = 120, d₁ = 16 , then

\frac{1}{2} × 16 × d₂ = 120

8d₂ = 120 ( divide both sides by 8 )

d₂ = 15 cm
