7. The population of Flood River City is now 42,000. Experts predict the population will decrease 25% each
year for the next five years. What will be the population in five years?
Answer: The population after five years = 9967
Step-by-step explanation:
The exponential equation for population decay : [tex]P=A (1-r)^t[/tex], where A = initial population r= rate of decay , t= time
Given: A= 42000, r= 25%= 0.25, t= 5
then
[tex]P=42000(1-0.25)^5\\\\=42000(0.75)^5\\\\=42000(0.2373046875)\\\\\approx9967[/tex]
Hence, The population after five years = 9967
Fill in the blanks with the correct words:
An event that has probability O is said to be
An event that has probability 1 is said to be
Answer:
Impossible; certain to happen
Step-by-step explanation:
Probability = 0 applies to an event which cannot happen. Example: roll a die and get a 7.
Probability = 1 applies to an even which is certain to occur. Example: roll a die and get a number less than 8.
Trinity and Peyton were collecting box tops for their class. Trinity collected 36 box tops. Peyton collected
1 ½ times as many. How many cans did they collect all together?
Note: We need to find the number of total box tops instated of total number of cans.
Given:
Trinity collected 36 box tops.
Peyton collected [tex]1\dfrac{1}{2}[/tex] times as many as Trinity.
To find:
The number of box tops they did collect all together.
Solution:
It is given that,
Number of box tops collected by Trinity = 36
Number of box tops collected by Peyton = [tex]1\dfrac{1}{2}\times 36[/tex]
= [tex]\dfrac{3}{2}\times 36[/tex]
= [tex]54[/tex]
Total = [tex]36+54[/tex]
= [tex]90[/tex]
Therefore, the total number of box tops collect all together is 90.
Angie and Kenny play online video games. Angie buys 2 software packages and 3 months of game play. Kenny buys 1 software package and 1 month of game play. Each software package costs $30. If their total cost is $170, what is the cost of one month of game play?
Answer:
$20
Step-by-step explanation:
Kenny's gameplay: 1 month
Angie's gameplay: 3 months
1+3= 4
Kenny bought 1 software pack
Angie bought 2 software packs
1+2= 3
Each software package= $30
So 30×3= 90
Total cost= $170
170-90= 80
80÷4= $20

Answer:
x² - 2x - 15 = 0Step-by-step explanation:
Roots:
x₁ = -3, x₂ = 5The equation:
(x - x₁)(x - x₂) = 0(x - (-3))(x - 5) = 0(x + 3)(x - 5) = 0x² + 3x - 5x - 15 = 0x² - 2x - 15 = 0Step-by-step explanation:

Incase you can’t see the picture, it says “Explain how to solve the following equation and check for extraneous solutions: x= square root of -2x+6 then out of square root +3 Please help guys
Answer:
x=3
Step-by-step explanation: too much math to put here
Answer:
x= 3 ; (x=1 is an extraneous solution)
Step-by-step explanation:
-2x+6 is under a square root, so its value must be > or equal to 0
If we solve the inequality
-2x+6 ≥ 0 we obtain
-x+3≥ 0
-x ≥ -3
x ≤ 3
now that we know the possible values of x we can proceed like this:
1) move 3 on the left side of equal and change its sign
x-3 = √-2x+6
2) square the two members of the equation
x^2 + 9 -6x = -2x+6
3) solve the equation
x^2 -4x +3 = 0
(x-3)(x-1) = 0
x = 3
x = 1
4) Check if the solution are ≤ 3 and if they make true the equation
Both solutions are ≤ 3
if x = 3
3 = √-6+6 + 3
3 = 3
true
x=1
1 = √-2+6 + 3
1 = 2+3
1 = 5 false
In conclusion we can say the 3 is a real solution, while 1 is an extraneous solution

Finding the product of 9, 10 and 9 ; 810
Step-by-step explanation:
Given that :
Length = 10 feets
Width = 9 feets
Height = 9 feets
The volume of a rectangular prism is obtained by :
Length * width * height
The volume could be obtained by taking the product of 10, 9 and 9
Hence, the volume of the rectangular prism is :
(10 * 9 * 9) feet³ = 810 feet³
Number of 1 feet³ boxes = 810 feet³ / 1 feet³ = 810

Answer:
H=22.5 in
The answer is A
Step-by-step explanation:

Evaluate F (-5) and f(2) without a calculator 
Answer:
f(x) = 3x2 + 5 and y = 3x2 + 5
Step-by-step explanation:
The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5.
In a right triangle one angle measure 28° more than the other acute angle. Use equations to solve for the measures of the two unknown angles.
Answer:
One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.
Step-by-step explanation:
In the right angled triangle one angle is always equal to 90 degrees.
Suppose <a= 90 degrees
< b= x degrees
< c= x+28 degrees
The sum of all the angles of the triangle are always equal to 180 degrees
therefore
<a+ <b+<c= 90 + x+ x+28 = 180
or
2x= 180- 28- 90
2x=62
x= 31 degrees
One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.
An acute angle is an angle which has less than 90 degrees in measurement .
Hence both angles of the right angle triangle are acute angles , 31 and 59 degrees.
In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angle.
Write and solve an equation to determine the measure of angle x.
Answer:
X =50 Y is also 50 since they are vertical angles
Step-by-step explanation:
70+ 60 + X = 180 (the 3 angles form a straigh line = 180 )
130 +X =180
X = 180-130
X=50

hello my friend is from 7th grade she need help with her math 5200 at 49% for 3years??
Answer:
At the end you will have 12,844$ and you have earned 7644$
Step-by-step explanation:
49% 49 times the money 5,200$ = 254,800 divided by 100 = 2548 in 1 year.
Times 2548 by 3 and get 7644$ ( Interest Earned ) add that by original money and get 12,844$ (Money In Total)
In a class of 19 students, 12 are female and 13 have an A in the class. There are 4 students who are male and do not have an A in the class. What is the probability that a student chosen randomly from the class does not have an A?
answer is
6/19
× whats the point of this
The likelihood of selecting a classmate at random who does not have an A is 6/19.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
To find the probability of a student not having an A, we need to first find the total number of students who do not have an A.
The number of students who have an A is 13, so the number of students who do not have an A is:
19 - 13 = 6
Out of these 6 students, 4 are male and 2 are female.
So, the probability of choosing a student randomly who does not have an A is:
P(not A) = number of students without an A / total number of students
P(not A) = 6 / 19
Therefore, the probability of choosing a student randomly from the class who does not have an A is 6/19.

Find the missing measure of the arc formed by the endpoints of a central angle.
Answer:
The missing measure of the arc is 125°.
Step-by-step explanation:
Since the circle is 360°, you would first subtract 360 by the degrees given: 360-115-35-85 and the sum is 125. Then, you would set 125 equal to -32x-3 to solve for x.
[tex]125=-32x-3[/tex]
[tex]+3[/tex] [tex]+3[/tex]
-----------------------
[tex]\frac{128}{-32} =\frac{-32x}{-32}[/tex]
[tex]x=-4[/tex]
The missing measure of the arc is 125°.
Does anyone know this?
True or False: If I solve for the angle measure to the nearest 1/10th of a degree, the answer is 50.90
