Answer:
40
Step-by-step explanation:
30/12=2.5
20/2.5=8
8+8+12+12=40
60 divided by 5 is 12, so one pizza is 12$. then do 9 times 12 and you'll get 108. so 9 pizzas cost 108$.
so 25 - 13 = 12 so then your going to divide 12 by the number of tickets he bout so it would look like 12/6 which comes out to 2 so each ticket costs $2
Answer:
49°
Step-by-step explanation:
90 - 41 = 49
The angle shown is 90° so to figure out the second angle, subtract 41° from 90° to get the second angle.
Answer:
Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.
The school decided to cover the semicircles with grass to create a space for stretching and other activities.
To Find: area of one of the semicircles at either end of the track
How many square yards of grass will the school need to cover the entire circle?
Solution:
Diameter of semicircle = 70 yards
Radius of semicircle = 70/2 = 35 yards
Area of semicircle at one end = (1/2)πr²
= (1/2)(22/7)35²
= 1,925 sq yards
area of one of the semicircles at either end of the track = 1,925 sq yards
square yards of grass will the school need to cover the entire circle
= 2 x 1,925
= 3850 sq yards
distance around one of the semicircles at either end of the soccer field = πr = (22/7) 35 = 110 yards
distance around the inner lane of the track = 100 + 100 + 110 + 110
= 420 yards
