how many sides does a regular polygon have if the measure of an interior angle is 160 degrees? justify ur answer EXPLAIN HOW PLSSS
Step-by-step explanation:
Size of Interior angle = 180° - 360°/n, where n is the number of sides of the regular polygon.
We have 180° - 360°/n = 160°.
=> 360°/n = 20°, n = 18.
Therefore it is a 18-sided regular polygon.

[tex]\frac{4^{9} }{4^{3} }[/tex]
9x9x9x9divide by 4x4x4
Answer:
4⁹ / 4³ = 4⁶ = 4096
Step-by-step explanation:
You can solve this by realising that exponents (the 9 and the 3 in this case), simply tell you how many times to multiply the numbers together.
What you're see there then can also be expressed as:
[tex]\frac{4 \times 4 \times 4 \times 4 \times 4 \times 4 \times 4 \times 4 \times 4}{4 \times 4 \times 4}[/tex]
Because the numerator and denominator are all multiples of the same number repeatedly, you can simply eliminate the bottom three fours from the top and bottom, giving you:
[tex]\frac{4 \times 4 \times 4 \times 4 \times 4 \times 4 \times (4 \times 4 \times 4)}{(4 \times 4 \times 4)}\\\\= 4 \times 4 \times 4 \times 4 \times 4 \times 4[/tex]
[tex]4 \times 4 \times 4 \times 4 \times 4 \times 4[/tex]
A simpler way to look at it is to understand that when the same number is being raised to different bases, and then multiplied or divided, you can simply add or subtract the exponents. For example, speaking very generically:
[tex]x^a \times x^b = x^{a + b}[/tex]
and
[tex]x^a \div x^b = x^{a - b}[/tex]
In this case then, we can simply say:
[tex]\frac{4^9}{4^3} = 4^{9 - 3} = 4^6[/tex]
So when simplified, the expression is equal to 4⁶, or 4096.

if 50% is 15 what is 75%
Answer:
22.5
Step-by-step explanation:
50% of a number is 15
let the unknown number be = x
[tex] \frac{50}{100} \times x = 15[/tex]
[tex]x = 15 \div \frac{50}{100} [/tex]
[tex]x = 15 \times \frac{100}{50} [/tex]
[tex]x = \frac{1500}{50} [/tex]
[tex]x = 30[/tex]
75% of 30:
[tex] \frac{75}{100} \times 30 = 22.5[/tex]
The following data is from a simple random sample of 12 students GPAs. 3.12 2.45 4.0 3.76 3.54 2.78 3.39 3.21 1.98 3.43 3.98 2.77 Develop a point estimate of the population mean.
Answer: 3. 2
Step-by-step explanation:
Given the data:
3.12 2.45 4.0 3.76 3.54 2.78 3.39 3.21 1.98 3.43 3.98 2.77
Point estimate of population mean :
Σx / N
(3.12 + 2.45 + 4.0 + 3.76+ 3.54 + 2.78 + 3.39 + 3.21 + 1.98 + 3.43 + 3.98 + 2.77)
= 38.41 / 12

What is measure p angles has 5 sides
Answer:
[tex]\huge\boxed{m\angle P = 94\textdegree}[/tex]
Step-by-step explanation:
In order to answer this question, we need to note a couple of things about the angle relationships in a pentagon.
A) The sum of the measures in a pentagon will be 540° (We know this because the angle sum formula tells us that an n sided polygon angles will have a sum of [tex](n-2) \cdot 180[/tex] - 180 * 3 = 540).B) Equations can represent angle measures, added together will help us determine their value.Since we know the sum of all of the angles will be 540, we can create an addition statement to find out the value of x.
[tex]132 + (4x-10) + (5x-11) + 128 + (4x+2)=540[/tex]
Let's solve for x.
Combine the angles we already know:[tex]132 + 128 =260[/tex] Combine like terms: [tex]260 + 13x - 19=540[/tex] Add 19 to both sides, subtract 260 from both sides: [tex]13x =299[/tex] Divide both sides by 13: [tex]x = 23[/tex]Now that we know the value of x, we can substitute it into the expression for point P ([tex]4x+2[/tex]) to find it's value.
[tex]4 \cdot 23 + 2[/tex] [tex]92+ 2[/tex] [tex]94[/tex]Therefore, the angle of measure P is 94°.
