A. X=81
B. Y=99
C. Z=129
A triangle equals 180 degrees so all the numbers inside the triangle must add up to 180. Therefore you do 48+51-180 to give you x. Then subtract the number you got for x from 180 to find y and subtract 51 from 180 to find Z
Answer:
see explanation
Step-by-step explanation:
1 revolution is equivalent to the circumference of the wheel
1 revolution = πd ( d is the diameter )
= 70π cm
50 revolutions = 70π × 50 = 3500π cm = 35π m ≈ 110m ( nearest metre )
70 = 1 x 70, 2 x 35, 5 x 14, and 7 x 10. It is usually written as 1,2,5,7,10,14,35,70
86 = 1 x 86 or 2 x 43. It can be written as 1,2,43,86
154 = 1 x 154, 2 x 77, 7 x 22, 11 x 14. Can be written as 1,2,7,11,14,22,77,154
238 = 1 x 238, 2 x 119, 7 x 34, or 14 x 17. Can be written as 1,2,7,14,17,34,119,138
Miranda's I think because her car may take more gas but it goes a farther distance
Each student pays 7.25 for lunch.
Multiply that by 25 for the total lunch cost: 25 * 7.25 = 181.25.
Subtract the lunch total from the total cost to find the total ticket amount:
443.75 - 181.25 = 262.50
Now divide total ticket amount by 25 students to find the cost of one ticket:
262.50 / 25 = $10.50
The first choice is the correct answer.
