Find the number of sides of a regular polygon if one interior angle is 120 degrees A3 B4 C5 D6
Answer:
n = 6
Step-by-step explanation
Number of sides = 360/Measure of exterior
Measure of exterior = 180 - interior angle
Exterior angle = 180 - 120
Exterior angle = 60 degrees
Substitute into the formula
number of sides = 360/60
number of sides = 6
Hence the number of sides required is 6

Jerry played with 333 friends today, all at different times. He played with Tommy for 1\dfrac{7}{8}1 8 7 1, start fraction, 7, divided by, 8, end fraction hours, then Nathan for 1\dfrac{3}{4}1 4 3 1, start fraction, 3, divided by, 4, end fraction hours, then Chris for \dfrac{3}{2} 2 3 start fraction, 3, divided by, 2, end fraction hours. How many hours did Jerry play with his 333 friends today?
Answer:
8 1/8 hours
Step-by-step explanation:
Jerry played with 3 friends today, all at different times.
Tommy = 1 7/8 hours
Nathan = 1 3/4 hours
Chris = 3 3/2 hours
How many hours did Jerry play with his 3 friends today?
Number of hours Jerry play with his 3 friends today = 1 7/8 + 1 3/4 + 3 3/2
= 15/8 + 7/4 + 9/2
= (15+14+36)/8
= 65/8
= 8 1/8 hours

. Find f(3) for the following function
[tex]f(x)=3(2)^x+6[/tex]
a.f(3) = 222
b.f(3) = 9
c.f(3) = 24
d.f(3) = 30
Answer:
[tex]\boxed {\boxed {\sf D. \ f(3)= 30}}[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)= 3(2)^x+6[/tex]
We want to find f(3), so we must substitute 3 in for x.
[tex]f(3)= 3(2)^3+6[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve the exponent first.
2³= 2*2*2= 4*2= 8[tex]f(3)= 3(8)+6[/tex]
Multiply 8 and 3.
[tex]f(3)= 24+6[/tex]
Add.
[tex]f(3)=30[/tex]
For the function given, f(3) is 30.

Which set of values makes the inequality n > -5 true?
A
{-5, -5.5, -6}
B
{-5, -4.5, -3}
С
{-6,0,5}
D
{-6, -7,-8}
Answer:
B
Step-by-step explanation:
≥ means that it is greater than or equal to.
Any set that has all numbers over or equal to -5 would be correct, meaning that -5, -4.5, and -3 would be correct.
Hope this helps. Have a nice day.
Inequalities help us to compare two unequal expressions. The set of values makes the inequality n > -5 true is {-5, -4.5, -3}.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
As we need to find the values that will satisfy the inequality n≥-5, therefore, we need values that are greater than or equal to -5.
Hence, the set of values makes the inequality n > -5 true is {-5, -4.5, -3}.

Which of the following expressions are equivalent to -4/7 - 8/9 + 4/7 + 9/8?
Answer:
C and D
Step-by-step explanation:
I'm too braindead to explain this, read comments
Answer:
-2 1/72
Step-by-step explanation:
Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.

10x - 12y = 22
5x - 6y = 11 elimanation
Answer:
This is an identity or infinite solutions
Step-by-step explanation:
10x - 12y = 22
5x - 6y = 11
-2(5x - 6y = 11 )
-10x + 12y = -22
10x - 12y = 22
0=0
Identity solution
Answer:
2(5x - 6y = 11)= 10x - 12y = 22 so they are the same equation

Which expression is the factorization of x^2+10x+21?
Answer:
To factor a trinomial in the form Ax^2 + Bx + C when the A = 1. You need to find the factors of C that when added or subtracted will give you B.
Factors of 21 are either 1,21 or 3,7. Since +3 and +7 will give you 10 then those will be the two factors you will use.
Factoring x^2+10x+21 will give you (x+3)(x+7)

25. Multi-A carpenter is making a tray to fit between two circular pillars in the shape of the shaded area as shown. She is using a jigsaw to cut along the edge of the tray. What is the length of the cut encompassing the tray? Round to the nearest half foot.
Answer:
21.5 feet.
Step-by-step explanation:
Calculate the length of a curved edge.
s =
m
360
· 2πr Use the formula for arc length.
=
90
360
· 2π(3) Substitute 3 for r and 90 for m.
= 1.5π Simplify.
Let t be the length of the cut encompassing the tray.
t = 2 · 1.5π + 2 · 6
= 3π + 12 Simplify.
≈ 21.5 ft Use a calculator to evaluate. Then round your answer to the nearest half foot.
The length of the cut encompassing the tray is 21.5 feet.
