Answer:
200
Step-by-step explanation:
You can simply just graph it and see where the points intersect, or you can do it algebraically.
0.45x+29.99=0.40x+39.99 subtract 29.99 both sides
0.45x=0.40x+10.00 subtract .40x both sides
0.05x=10.00 divide both sides by 0.05
x=200
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.

Plssss helppppp, this is geometry
Answer:
Step-by-step explanation:
measure angle b
add it with 90
90 + b = A
and create an angle with the measure of sum (A)
Answer:
90
Step-by-step explanation:
the question sat sum of A'angle and B'angle.
so A+B=180
so when you subtract 180-90=90
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

This is the same as writing [tex]-18w^7[/tex]
=====================================================
Explanation:
The three terms we are multiplying are:
3w^(-2)2w^6-3w^3The coefficients of those terms are: 3, 2, -3
Multiplying the coefficients gets us 3*2*(-3) = -18 which is the coefficient of the final answer.
As for multiplying the w terms, we add the exponents: -2+6+3 = 7, and this is the exponent of the final answer.
Wrapping everything up, that's how we end up with -18w^7
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)

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.

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.

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.

Answer:

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

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.
