Answer:
<em>( - y - 3 , - x - 1 ) </em>
Step-by-step explanation:
( x , y ) ----> ( - y , x ) ----> ( - y - 3 , x + 1 ) ----> <em>( - y - 3 , - x - 1 )</em>
Answer:
She should order 12 pizzas.
Step-by-step explanation:
5 pizza for every 20 students gives us the ratio 5:20.
5/20 = 0.25 = the amount of pizza each student gets.
If there are 48 students, you would just multiply 0.25 * 48 to get your answer.
Area = L x W
Area = (y+5) (y-5)
Use Foil to multipy (First, Outer, Inner, Last)
Area = y² -5y + 5y -25
Area = y² -25
Answer:
= 30.144 km²
Step-by-step explanation:
Area of a sector is given by the formula;
θ/360 × πr², where θ is the angle subtended by the arc to the center of the circle, and r is the radius.
Area = 54/360 × 3.14 × 8 × 8
= 30.144 km²
