Answer:
No
Step-by-step explanation:
8 marbles cost $2.32. He needs 32 more cents.
Answer:
subtract 2a + 3b - 3b =5 - 3b
simply 2a = 5 -3b
divide both sides by 2 . 2a over 2 = 5 over 2 - 3b over 2
simply a= 5- 3b over 2
Answer:
Conclusion: x = 0
Step-by-step explanation:
given: If a ● b = 0, then a = 0 or b = 0
then for 3x = 0, either 3 = 0 (not possible because 3 is obviously not zero) or x = 0 (answer)
Answer:
The area of the sector is 8*pi cm² or 25.13272 cm².
Step-by-step explanation:
In order to calculate the area of a circular sector we can apply a rule of three in such a way that the circle's area, pi*r² cm², is related to 360º in such a way that "x" cm² is related to the angle of the sector. We have:
pi*r² cm² ---------> 360º
x cm² ------------> 80º
pi*r²/x = 360/80
360*x = 80*pi*r²
x = 80*pi*r²/360
x = 80*pi*(6)²/360
x = 80*pi*36/360
x = 8*pi cm²
The area of the sector is 8*pi cm² or 25.13272 cm².
