Answer:

Nope.

Hey mate, here is your answer. Hope it helps you.

Step-by-step explanation:

No,not all polygons have symmetry. Only regular polygons who have same number of sides have point symmetry. Point Symmetry is when every part has a matching part the same distance from the central point but in the opposite direction.

A student has $1 bills and $5 bills in his wallet. He had a total of 15 bills that are worth $47. How many of each type does he
Mrrafil [7]

Total number of $1 bills=7

Total number of $5 bills=8

Further explanation:

Given

Let x be the number of $1 bills

and

y be the number of $5 bills

Then according to the given statements

x+y=15

x+5y=47

From first equation:

x+y=15\\x=15-y

Putting x=15-y in second equation

x+5y=47\\15-y+5y=47\\4y=47-15\\4y=32\\\frac{4y}{4}=\frac{32}{4}\\y=8

Putting y=8 in first equation

x+8=15\\x=15-8\\x=7

Hence,

Total number of $1 bills=7

Total number of $5 bills=8

The area of a triangle is 24 square inches. What is the height of the triangle if the base length is 6 inches?
ikadub [295]
The height should be 8 because the area of a triangle is b*h/2 so 6*8= 48/2=24 so the height is 8.

Answer:

X = 50

Step-by-step explanation:

I believe these two angles are called verticle angles.  This means that 147 = 3x-3 (key information).  Now that we know that, we can solve for x.

<h2>147 = 3x - 3</h2><h2>150 = 3x</h2><h2>\frac{150}{3} = \frac{3x}{3}</h2><h3>x = 50</h3>
