Answer:
182 cm³
Step-by-step explanation:
Let x cm³ be the total volume of the glass.
1/2 x + 65 = 6/7 x
by multiplying both sides by 2, we have
x + 130 = 12/7 x
5/7 x = 130
x = 182
On the bottom line, the 106 and number 1 make a straight line and needs to equal 180 degrees.
This means number 1 = 180-106 = 74 degrees.
Because x and y are parallel, the top outside angle is the same as number 1.
6x +8 = 74
Subtract 8 from both sides:
6x = 66
divide both sides by 6:
x = 66 / 6
x = 11
Now you have x, replace x in the equation for 7x-2 to find that angle:
7(11) -2 = 77-2 = 75 degrees.
The three inside angles need to equal 180 degrees.
Angle 2 = 180 - 74 - 75 = 31 degrees.
6 - 6, 12, 18, 24, 30, 36, 42, 48 54, 60, 66, 72, 78, 84, 90, 96
Answer:
B) 3
Step-by-step explanation:
This is because they are both circles and they each have the same equation for circumference. C=2πr
So that if pi stays x 2 then the perimeter will still be 3 x as big as the smaller circle. Which means it takes 3 full turns as to turn around the perimeter.
