Complementary: When two angles add up to 90 degrees
Supplementary: When two angles add up to 180 degrees
Similarities are both involve two angles, the difference is the total degrees they add up to.
A stadium has 47,000 seats. Seats sell for $35 in Section A, $20 in Section B, and $15 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,482,000 from each sold-out event. How many seats does each section hold?
Answer - its 31
step by step
If it takes a fan 12 minutes to walk her seat in the last section in the stadium and it takes 7 minutes to get to the
lowest-level seats, what is the average time to find a seat in these two sections at the stadium?
Answer:
9.5
Step-by-step explanation:
Probably wrong, but to find average you add up 12+7 then divide by 2, that is 19/2 which is 9.5
The average value of the time is 9.5 minutes.
What is average?"The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set".
For the given situation,
Time to walk in the stadium are 12 minutes and 7 minutes.
Number of values = 2
Formula to find average,
Average = Sum of Values/ Number of values
⇒ [tex]Average = \frac{12+7}{2}[/tex]
⇒ [tex]Average = \frac{19}{2}[/tex]
⇒ [tex]Average = 9.5[/tex]
Hence we can conclude that the average value of the time is 9.5 minutes.

Which shows how to solve the equation 5 x = 80 for x in one step?
-(-5)X = 80(-5)
(5)x=80(5)
Help pls
Answer:
The second one.
Step-by-step explanation:
With the equation -4/5x=80, you need to multiply the reciprocal of the fraction in order to isloate x so that you can solve. Therefore, the second answer seems to best represent this.

determine whether the function is even odd or neither
Answer:
neither
Step-by-step explanation:
If the graph is symmetric by the y-axis the function is even OR we can say that
f(x) = f(-x) for the function to be even
for f(3) = 2 and f(-3)= 2 works yet
for f(2) = 0 and f(-2) = 1 NOT an even function
f(-x) = -f(x) will make the function odd
f(-3) = 2 and -f(3) = -2 NOT an odd function
f(-x) ≠ -f(x) will make the function neither
f(-3) = 2 ≠ -f(3) = -2 the function is neither odd or even

2x +94 = 18043°Step-by-step explanation:
The sum of angles in a triangle is 180°. We are told the measures of the three angles are ...
x + x + 94 = 180
2x +94 = 180 . . . . . . equation to solve for x
2x = 86 . . . . . . . subtract 94
x = 43 . . . . . . divide by 2
The congruent angles each measure 43°.

Answer:
See Below
Step-by-step explanation:
The negation of a statement is almost like the opposite, but it needs to cover all cases that the statement does not.
1) x is not equal to 300.
This statement is true for all x except 300 while our original statement is true for all x except 100. These two have overlaps between what values of x could be, meaning that it is not the negation.
2) x is equal to 100.
This statement is true only for the case x equals 100 while our original statement is true for all the cases where x is not 100. These two do not overlap and cover all numbers. This means that it is the negation.
3) It is not the case that x is equal to 400.
This statement is true for all x except 400 while our original statement is true for all x except 100. These two have overlaps between what values of x could be, meaning that it is not the negation.
4) x is equal to 300.
This statement is true only for the case x equals 300 while our original statement is true for all the cases where x is not 100. This two cases have overlaps(300), meaning it is not the negation.

Noah started to solve the equation -4.6p - 6.3p + 3.9= 9.18 below.
1. Combine like terms: -10.9p+3.9=-9.18
Apply the next steps to solve the equation. What is the solution?
P= ?
9514 1404 393
Answer:
p = 1.2
Step-by-step explanation:
From here, it is a 2-step linear equation.
Step 1:
Identify the constant term on the side of the equation with the variable. Subtract that constant from both sides.
-10.9p = -13.08
Step 2:
Divide both sides by the coefficient of the variable.
p = -13.08/-10.9 = 1.2
The solution is p = 1.2.

Write an
equation of the line that passes through each pair of points.
(-3,9), (-3,-5)
Answer:
since slope(m) = y2 -y1/x2- x1
-5 - 9/ -3 - (-3)= -14/0
m = -14/0 (undefined)
using the formula
y-y1 = m(x -x1)
y - 9 = -14/0(x - (-3)
y-9 = -14/0(x + 3)
0 = -14( x+3). (cross multiplication)
0 = -14x - 42
14x = -42
x = -3( equation of the line)

Answer:
The value of the expression is 0.5.
Step-by-step explanation:
To evaluate, we need to do order of operations.
To solve, we start with the parenthesis because they come first in the order of operations.
-1+3[(10-12)³/(-16)]
-1+3[-2³/-16]
Now we do the second thing in the order of operations, which is to simplify the exponents.
-1+3[-8/-16]
Now we do the third thing left to do, which is to do division and multiplication from left to right.
-1+3[0.5]
-1+1.5
Now we do the last thing left to do, which is to do addition and subtraction from left to right.
0.5
So the value of this expression is 0.5.

Answer:
See below.
Step-by-step explanation:
The top is a square 3 cm by 3 cm.
The other 4 sides are rectangles. Each one is 4 cm by 3 cm.
Front: 4 cm * 3 cm = 12 cm^2
Back: 4 cm * 3 cm = 12 cm^2
Right: 4 cm * 3 cm = 12 cm^2
Left: 4 cm * 3 cm = 12 cm^2
Top: 3 cm * 3 cm = 9 cm^2
TOTAL: 12 cm^2 + 12 cm^2 + 12 cm^2 + 12 cm^2 + 9 cm^2
TOTAL: 57 cm^2
Bottom prism (blue):
Front: 5 cm * 6 cm = 30 cm^2
Back: 5 cm * 6 cm = 30 cm^2
Right: 5 cm * 6 cm = 30 cm^2
Left: 5 cm * 6 cm = 30 cm^2
Bottom: 5 cm * 5 cm = 25 cm^2
Top: 5 cm * 5 cm - 3 cm * 3 cm = 25 cm^2 - 9 cm^2 = 16 cm^2
TOTAL: 30 cm^2 + 30 cm^2 + 30 cm^2 + 30 cm^2 + 25 cm^2 + 16 cm^2
TOTAL: 161 cm^2
Explanation for area of top of bottom (blue) prism.
Notice that the entire bottom of the top (yellow) prism is connected to the bottom prism, so there is no area of the bottom of the top prism that adds to the total surface area of the composite solid. With the bottom prism's top surface it is different. Since the top surface of the blue prism is larger than the bottom surface of the yellow prism, there is a bit of top surface of the blue prism that is seen. That area is the area of the top surface of the blue prism minus the area of the bottom surface of the top prism.
5 cm * 5 cm = 3 cm * 3 cm = 25 cm^2 - 9 cm^2 = 16 cm^2
The area of the top surface of the blue prism is 16 cm^2
Total surface area of the composite solid:
57 cm^2 + 161 cm^2 = 218 cm^2
Answer:
57 cm^2
Step-by-step explanation:
4 (4x3) + (3x3) = 48 + 9 = 57 cm^2
Front: 12 cm2
Back: 12 cm^2
Right: 12 cm^2
Left: 12 cm2
Top: 9 cm^2
What is the answer for this Problem?
Answer:
Increasing on the interval(s) [tex]-2\leq x\leq -4[/tex]
Decreasing on the interval(s) [tex]-1\leq y\leq 1[/tex]
Step-by-step explanation:
Anytime the graph is going upward, the function is increasing. However, anytime the graph goes down, the function is decreasing. Look at the image below for further reference. Also, when the function is increasing, the slope is positive, and when the function is decreasing the slope is negative.
The increasing interval of the graph is -3
The decreasing interval of the graph is 0.5
Since the values are in the middle of the interval, it automatically becomes the answer.
