Geometry- please hurry!!
Answer:
1 is a polygon. 2 and 3 are not.
Step-by-step explanation:
For the first shape:
This shape is a polygon because the sides of the shape are straight, have angles, and do not intersect.
For the second shape:
This is not a polygon because of the lines being bent and having curvature.
For the third shape:
This is not a polygon because the lines intersect at a point.
For a shape to be a polygon, it must have 3 or more straight sides, angles, and no intersections.

write an expression for the area of the gym. Write an expression for the area of the cafeteria. Write an expression for the total area of the gym and cafeteria. Write an expression for the total perimeter of the gym and cafeteria.
Answer:
a. The expression for the area of the gym is 15·x
b. The expression for the area of the cafeteria is 15·x + 45
c. The expression for the total area of the gym and the cafeteria is 30·x + 45
d. The expression for the total perimeter of the gym and the cafeteria is 36 + 4·x
Step-by-step explanation:
The parameters of the given figures are;
The width of the figure, w = 15
The breadth of the gym, [tex]b_{gym}[/tex] = x
The breadth of the cafeteria, [tex]b_{cafeteria}[/tex] = x + 3
The shape of the area of the gym = A rectangle
The shape of the area of the cafeteria = A rectangle
a. The expression for the area, 'A₁', of the gym is given by the area of a rectangle which is Width × Breadth
The area of the gym, A₁ = The width of the figure × The breadth of the gym
Therefore, we have; The area of the gym, A₁ = w × [tex]b_{gym}[/tex]
A₁ = 15 × x
The area of the gym, A₁ = 15·x
b. The area of the cafeteria, A₂ = The width of the figure × The breadth of the cafeteria
The area of the cafeteria, A₂ = w × [tex]b_{cafeteria}[/tex]
∴ A₂ = 15 × (x + 3) = 15·x + 45
The expression for the area of the cafeteria, A₂ = 15·x + 45
c. The expression for the total area of the gym and the cafeteria, 'A', is given as follows;
A = A₁ + A₂
∴ A = 15·x + 15·x + 45 = 30·x + 45
The expression for the total area of the gym and the cafeteria = 30·x + 45
d. The expression for the total perimeter of the gym and the cafeteria, 'P', is given as follows;
P = The perimeter of the rectangular area of the gym plus the area of the cafeteria
∴ P = 2 × 15 + 2 × (x + x + 3)
P = 30 + 4·x + 6
P = 36 + 4·x
The expression for the total perimeter of the gym and the cafeteria P = 36 + 4·x.

Write the equation of the line through (2,-4) that is perpendicular to the line Y= 1/3x-4
Answer:
y + 4 = -3(x - 2)
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes. Since the slope of the given line is 1/3, a perpendicular line would have a slope of -3. We know that the line goes through the point (2 , -4), so we can use point-slope form to write an equation.
Point slope: [tex]y-y_{1} =m(x-x_{1})[/tex]
y + 4 = -3(x - 2)
If necessary, this can be written in slope-intercept form as well. In this case, you'd solve for y.

x-6/9=-5
Answer:
x = -13/3
Step-by-step explanation:
Given: x-6/9 = -5
You want to isolate the variable (x).
To make this easier, turn -5 into -45/9 (common denominator w/ -6/9)
Then, add -6/9 to -45/9.
x = -39/9
Simplify.
x = -13/3
Costco sells hotdogs in packs of 8 and hotdog buns in packs of 12. If you want to buy an equal number of hotdogs and hotdog buns, what is the least number of each that you can buy?
Answer:
24 hotdogs
Step-by-step explanation:
Costco sells hotdogs in packs of 8 and hotdog buns in packs of 12. If you want to buy an equal number of hotdogs and hotdog buns, what is the least number of each that you can buy?
We solve using the Lowest Common Multiple Method.
Find and list multiples of 8 and 12 until the first common multiple is found. This is the lowest common multiple.
Multiples of 8:
8, 16, 24, 32, 40
Multiples of 12:
12, 24, 36, 48
Therefore,
LCM(8, 12) = 24
Therefore, the least number of each that you can buy is 24 hotdogs

A farmer had 90 black sheep and 10 white ones. What fraction of the flock is black?
Answer:
90%
Step-by-step explanation:
In hockey, Ed makes 7 goals for every 10 shots. If he takes 6 shots, what is the probability that he will make at least 5 goals?
================================================================
Explanation:
Let's consider the case where Ed makes all 6 shots. The probability of this happening is (7/10)^6 = 0.117649
Let A = 0.117649 so we can use it later.
----------------
Now consider the case where Ed makes exactly 5 shots. So he misses exactly 1 shot. Furthermore, consider the case where his first shot is a miss and the remaining 5 shots are successful.
The probability of getting the first shot a miss and the remaining 5 successful is (3/10)*(7/10)^5 = 0.050421
Note how 3/10 and 7/10 add to 1. The 3/10 is the probability of getting a miss (since he makes 7 goals for every 10 shots, he misses those 3 goals).
The value 0.050421 represents the probability for that first shot being a failed attempt while the rest are successful shots. Since there are 6 slots total, this means 6*0.050421 = 0.302526 represents the probability of missing exactly one goal and hitting the others. By this point, we aren't making the failed attempt at slot 1. It could be at any slot. For instance, the failed attempt could be at slot 4.
In other words, 0.302526 is the probability of making exactly 5 shots.
Let B = 0.302526
----------------
To recap,
A = probability of getting all 6 shots in the goal (no failed attempts).B = probability of getting exactly 5 shots in the goal (exactly one attempt failed).These two events are mutually exclusive. They cannot happen at the same time. That allows us to add the values of A and B to get the final answer
A+B = 0.117649+0.302526 = 0.420175
Therefore, A+B = 0.420175 represents the probability of either getting all 6 shots in the goal OR getting exactly five shots in the goal.
In short, 0.420175 represents the probability of making at least 5 shots. The phrasing "at least 5" means "5 or more".
-----------------
If you wanted to calculate this in one line, then you could say
(7/10)^6 + 6*(3/10)*(7/10)^5 = 0.420175
This decimal value is exact.
