Answer:
7 sides
Step-by-step explanation:
The sum of exterior angles of a polygon is 360°.
Now, exterior angle of the point with interior angle of 120 is; 180 - 120 = 60 (angle on a straight line)
For the others, it is; 180 - 130 = 50
Thus;
60 + 50n = 360
50n = 360 - 60
50n = 300
n = 300/50
n = 6
Thus,number of sides = 6 +1 = 7 sides

The interest of $4000 in 2 years is 500. what is the simple interest rate?
Answer:
0.0625/year or 6.25%/year
Step-by-step explanation:
Simple interest formula:
I = Prt where I = interest (final) amount, P = principal (initial) amount, r = interest rate, t = time (years)We are given these values:
I = $500 P = $4000 t = 2 yearsWe want to find r, the simple interest rate.
Substitute these known values into the formula.
I = Prt 500 = (4000) × r × (2) 500 = 8000r 0.0625 = rThe simple interest rate is 0.0625, aka 6.25% per year.

A method of calculating interest using 365-day year is the(?) method.
(Quantitative literacy)
Step-by-step explanation:
To calculate the interest payment under the 365/360 method, banks multiply the stated interest rate by 365, then divide by 360. However, due to the numerator and denominator not matching, the 365/360 method has been held to increase the effective interest rate by 0.01389 in a non-leap year.I need to know how to simplify 18 - 9 x (-4) ÷ 3 + 10 x 2

The required value of x = 12 and the side length of the triangle is 12 units. which is determined by Pythagoras's theorem.
What is Pythagoras's theorem?
Pythagoras's theorem states that in a right-angled triangle, the square of one angle is equal to the sum of the squares of the other two sides.
The given triangle is a right-angled triangle.
As per Pythagoras's theorem,
⇒ a² + b² = c²
Here a = 16, b = x and c = 20
Substitute the values in the formula,
⇒ 16² + x² =20²
⇒ 256 + x² = 400
⇒ x² = 400 - 256
Apply the subtraction operation,
⇒ x² = 144
⇒ x = √144
⇒ x = 12
Therefore, the required value of x is 12 units.

Answer:
1) Z = 3.17
2) 4.69 or √22
3) X = 42°
4) X = 60°
Step-by-step explanation:
1) (4)(8+4) = (Z)(Z+12)
48 = Z² + 12Z
Z² + 12Z -48 = 0
(Z +15.17)(Z - 3.17) = 0
Z = 3.17
2) (2)(11) = Y²
y² = 22
Y = 4.69 or √22
3) 180° - 139° = 41°
41° = 1/2(40° + X)
41° = 20° + 0.5X
21° = 0.5X
X = 42°
4) X = 1/2(240°-120°)
X = 1/2(120°)
X = 60°

A sandwich shop offers 3 different kinds of bread, 4 different kinds of meat, and 6 different toppings. How many different sandwiches with one bread, one meat, and one topping are possible?
Answer:
yeah
Step-by-step explanation:
0
Your second impression was "right"; the answer is 36 in one restricted interpretation of the problem, in which a sandwich has precisely one type of bread, one type of meat, and one type of cheese.
The largest possible interpretation is that a sandwich consists of a top bread, 1 to 3 types of meat, 1 to 3 types of cheese, and a bottom bread which could be different from the top slice of bread (but two sandwiches are considered the same if the only difference is turning one upside down). The answer to that problem involves, for example, seven possible combination of meats, and is
(42)bread⋅(23−1)meat⋅(23−1)cheese=6⋅7⋅7=594
If you must use the same type of bread top and bottom the answer is
(41)bread⋅(23−1)meat⋅(23−1)cheese=4⋅7⋅7=396

Answer:x=−8 and y=8
Step-by-step explanation: Do you want it solved step by step?
Answer:
One solution, (-8,8)
x = -8
y = 8
Step-by-step explanation:
-6x + 3y = 72 then 3y = 72 + 6x, y = 24 + 2x
5x + 8y = 24
substitute for y:
5x + 8(24 + 2x) = 24
5x + 192 + 16x = 24
21x = -168
x = -8
y = 24 + 2(-8) = 8

i have 4 questions on here and i don’t understand it.
Answer:
Step-by-step explanation:
y = mx + b, where "m" - slope, "b" - y-intercept
Slopes of parallel lines are the same and y-intercepts are different.
P ( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
~~~~~~~~~~~~
y = 6x + 1 , m = 6
( - 7, 1 )
y - 1 = 6[x - ( - 7 )]
y = 6(x + 7) + 1
y = 6x + 43

A classroom has 60 students in total
42 can swim
46 can bike
50 can skate
55 can badminton
How many students can play all 4 sports
Answer: You see if out of the 60 students in total42 can swim46 can bike50 can skate55 can badmintonThen there must be some students who are playin all sports because if each student played one sport, there would be 193 students in total, not 60. Since we know this, it must be wise to say that the lowest number of students playing sports one, is the lowest number of students playing all 4 sports to add up to 60.

If a rocket travels 68,732 milometers in 3 hours, what is it's speed?
a) 23,000 Km/hr
b) 23,000 hr/km
c) 22,910 hr/km
d) 22,911 km/hr
Answer:
v = 0.0229 km/h
Step-by-step explanation:
Given that,
Distance, d = 68,732 milometers = 0.0687 km
Time, t = 3 hours
We need to find the speed of the rocket. The speed of an object is given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{0.0687}{3}[/tex]
v = 0.0229 km/h
So, the speed of the rocket is 0.0229 km/h.

Answer:
(4,8)
Step-by-step explanation:
4 + 8 = 12
3(4) + 8(8)
= 12 + 64
= 76
The possible solutions are (4,8),(4,6),(2,8)
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given;
The sum of two numbers =12
The sum of 3 times the first number and 8 times the second number=48
Solving (4,8)
4+8=12
3*8+8*4=24+32=56
(8,6)
8+6=14
(4,6)
=4+6=10
3*4+8*6=12+48=60
(2,8)
2+8=10
3*2+8*8=6+64=72
Therefore, the possible outcomes of algebra will be A,C and D.
