What is the sum of the interior
angle measures of a polygon
that has 7 sides?
Sum = [?]
Hint: Sum = (n-2)180
Answer:
Sum = 900 degrees.
Step-by-step explanation:
Sum = (n-2)180
=(7-2)180
=(5)180
=900
Answer:
900 degrees
Step-by-step explanation:
The formula for calculating the sum of the interior angles of a regular polygon is : ( n - 2) × 180°. when n is number of sides.
Sum of angles = ( n-2) × 180
Sum of angles = (7-2) × 180
Sum of angles = 5 × 180
Sum of angles = 900 degrees
There will be 6 people at Eli's cake party. She wants to bake enough cake so that each person she feeds eat at least 1/5 of the cake. What is the minimum number of cakes you should bake?

Suppose a - b = 0Which one of these expressions equals ab?
A. 2a
B. 0
C. b^2
D. 2b
E. a/b
If a-b=0, a=b, so ab=bb=b^2
Answer:
b^2
Step-by-step explanation:
a - b = 0
Add b to each side
a-b+b = 0+b
a=b
We want to find ab
Replace a with b
b*b
b^2

Tasha is packing gift bags that include
the same items. She has 72 glow sticks,
36 markers, and 24 bottles of bubbles.
Tasha believes that she can pack no
more than 6 bags using all of her
supplies. Do you agree with Tasha? Explain.
Answer:
No, I do not.
She can pack up to 12 bags
Step-by-step explanation:
Given
[tex]Glow\ sticks = 72[/tex]
[tex]Markers = 36[/tex]
[tex]Bubbles = 24[/tex]
Required
Is Tasha correct?
The maximum number of bags she can pack is determined by the greatest common factors (GCF) of the items.
i.e. GCF of 72, 36 and 24.
This is calculated as:
[tex]24 = 2*2*2*3[/tex]
[tex]36 = 2 * 2 *3*3[/tex]
[tex]72 = 2 * 2 * 2 *3*3[/tex]
Multiply all common factors:
[tex]GCF = 2 * 2 * 3[/tex]
[tex]GCF = 12[/tex]
The GCF is 12.
This implies that she can pack up to 12 bags
