The average attendance at a local high school’s football games went down from 2,000 people to 1,840. What was the percent of decrease in attendance at the football games?
Answer:
8%
Step-by-step explanation:
Initial attendance = 2000
New attendance record = 1840
Percentage decrease in attendance :
((Initial - new attendance record) / initial attendance) * 100%
((2000 - 1840) / 2000) * 100%
(160 / 2000) * 100%
0.08 * 100%
8%
8% decrease in attendance
What name best describes this shape?
Answer: Quadrilateral
Explanation:
Any four sided polygon is considered a quadrilateral since "quad" means "four". You can think of a quad bike, which has four wheels, to help remember this math term.
Usually in problems like this, we'll be given information about if certain sides are parallel or the same length. However, we don't this info, so we cannot narrow down this classification anymore.
Forty-six students go on a field trip. The students are divided into groups of 7 students. How many groups of 7 will there be?
Answer:
6
Step-by-step explanation:
Given that :
The school children are going for a school field trip. There are total forty - six number of students for the field trip.
They are asked to form groups of seven students in a group.
Therefore they will form = [tex]$\frac{46}{7}$[/tex]
= 6.5
Therefore there will 6 number of groups having 7 students. And the remaining 4 students will form another group.
So there will be 6 groups of seven in each group.

4. Is the point (3,-4) a solution to the given system? Justify your answer.
y = 4x - 16
y = 2x + -6
Answer: No, it is not a solution
==========================================================
Explanation:
The point (3,-4) means that x = 3 and y = -4 pair up together
Let's plug these x,y values into each equation
Starting with the first equation, we get,
y = 4x-16
-4 = 4(3)-16 ... x replaced with 3; y replaced with -4
-4 = 12-16
-4 = -4 .... this is a true statement
Repeat for the second equation
y = 2x-6
-4 = 2(3)-6
-4 = 6-6
-4 = 0 ... this is false
Since we get a false statement, this means (3,-4) is not on the line y = 2x-6, which means that overall (3,-4) is not a solution to the system of equations. The point (3,-4) must make both equations true for it to be a solution.

Step-by-step explanation:
Probability that Dan chooses a Green card = 0.2
Probability that Esther chooses a Green card = 0.2 (same set of cards = same probability)
Since they are independent events,
total probability = 0.2 * 0.2 = 0.04.
help I will give brainiest
Answer:
c and b
Step-by-step explanation:
Answer:
B (4, 9)
Step-by-step explanation:
Isolate one of the variable on the first equation
5 = -x + y
turn to
x = y - 5
Then insert this into the second equation
3 = 3(y - 5) - y
Simplify-
3 = 3y - 15 - y
3 = 2y - 15
Add 15 to both sides
18 = 2y
Divide by 2
9 = y
knowing y = 9 you can assume that -
(x, 9)
This means the only possible answer is B

What is the average rate of change for f(x) = 2 ^ x - 12 over the interval 4 <= x <= 8
Answer:
The everage rate of change over the interal 4 ≤ x ≤ 8 will be: 60
Step-by-step explanation:
Given the function
[tex]f\left(x\right)\:=\:2^x-\:12\:\:\:[/tex]
Interval : 4 ≤ x ≤ 8
or
Interval = [4, 8]
so
at x₁ = 4, f(x₁) = 2ˣ - 12 = 2⁴ - 12 = 16-12 = 4
at x₂ = 8, f(x₂) = 2ˣ - 12 = 2⁸ - 12 = 256 - 12 = 244
Using the formula to determine the average rate of change over the interval 4 ≤ x ≤ 8 wil be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [244 - 4] / [8-4]
= 240 / 4
= 60
Therefore, the everage rate of change over the interal 4 ≤ x ≤ 8 will be: 60

f(x)=(x+2)(x−4)
1) What are the zeros of the function?
2) What is the vertex of the parabola?
Answer:
(a) Zeroes of the function is -2,4.
(b) The vertex of the parabola is (1,-9).
Step-by-step explanation:
Given,
f(x)=(x+2)(x−4)
(a)To find the zeros of the function put f(x)=0.
(x+2)(x-4)=0
x+2 = 0 or x-4 = 0
x = -2,4
Hence, zeroes of the function is -2,4.
(b)Now,
f(x)=(x+2)(x−4)
[tex]f(x)= x^2 -2x+1 -1-8[/tex]
[tex]f(x)= (x-1)^2-9[/tex] .......(i)
We know that,
If [tex]f(x)=a(x-h)^2 +k[/tex] is the equation of parabola the (h,k) is the vertex of the parabola.
On comparing with equation (i), we get
h = 1
k = -9
Hence, the vertex of the parabola is (1,-9).

The Vertical position y (in feet) of a rock T seconds after it was dropped from a Cliff is given by the formula y= -60tsquared +4t+380. The base of a Clift corresponds to y=0 after how many seconds with a rock hit the ground at the base of the Cliff
Answer:
2.48 seconds
Step-by-step explanation:
The given function is
[tex]y=-60t^2+4t+380[/tex]
When [tex]y=0[/tex] the ball will be at the ground
[tex]0=-60t^2+4t+380[/tex]
[tex]\Rightarrow t=\dfrac{-4\pm \sqrt{4^2-4\left(-60\right)\times 380}}{2\left(-60\right)}[/tex]
[tex]\Rightarrow t=-2.48,2.55[/tex]
So, the time taken by the rock to hit the ground is [tex]2.48\ \text{seconds}[/tex].
Suppose you are driving. You notice that after driving for 4 hours, you are 135 miles from Seattle. You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. What is your rate? How far do you drive every 9 hours? How far from Seattle are you after driving for 17 hours?
Answer:
1,423
Step-by-step explanation:
Your average rate is 36.7 miles per hour over nine hours
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
In the first 4 hours, you've averaged 33.75 miles per hour, but this is apparently not sustainable, since at 9 hours you've only averaged 36.7 miles/hour.
You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. you've averaged 31.8 miles per hour
So the answer is that your average rate is 36.7 miles per hour over nine hours, although you did manage a faster burst of 50 mph for four hours once.
