So the ornament is $16.00-3/4% off=15.88
-3/4%=0.12 So, $16.00-0.12=15.88
The ornament costs $15.88.
If we divide 360 by the number of sides, 16, we will get the measure of one of the 16 central angles. 360/16 = 22.5. The vertex angle of one of the triangles that makes up this 16-gon is 22.5. That means that each of the base angles measure 78.75. If we put 2 of these triangles next to each other, 2 sides touching, the bases of both those triangles meet to form an interior angle. Two base angles of 78.75 together form the interior angle: 78.75+78.75 = 157.5. An interior angle measures 157.5. The exterior angle then has to measure 180-157.5 which is 22.5, same as the vertex angle of 1 of the triangles that make up this 16-gon.
to make 72 cookies you need to triple the amount of butter that you would need to make 24.
1.5 x 3= 4.5
You will need 4.5 cubes of butter.
Hope this helps!!
Answer:
Step-by-step explanation:
The error occured where the distributive property was applied. 3 × -4 should give us -12 not +12.
Here's the correct way to solve the equation
3(x - 4) = -9
3x - 12 = -9 (distributive property)
3x - 12 + 12 = -9 + 12 (addition property of equality)
3x = 3
3x/3 = 3/3 (division property of equality)
x = 1
