The correct answer is $241.1 each week and $964.4 each month
Explanation:
To calculate the amount Karen should receive, it is required to calculate the money she earned from Monday to Saturday and then the money she earned on Sunday as the amount paid per paper is different on Sunday.
Monday to Sunday:
Karen delivers 124 papers each day from Monday to Sunday. This means she delivers a total of 744 papers (124 papers each day x 6 days = 744 papers). Now, let's find the money she earned from Monday to Sunday:
744 papers x 18.2 cents = 13540 cents or 135.4 dollars (each dollar is equivalent to 100 cents, which means if you divide the cents into 100 you get the equivalent in dollars)
This means the total Karen earned from Monday to Saturday is $135.4
Sunday:
Karen delivers 151 Sunday papers and with each of these she earns 70 cents
151 papers x 70 cents = 10570 cents or 105.7 dollars
Total per week:
$135.4 + $105.7 = $241.1 each week, which is equivalent to $964.4 a month ($241.1 x 4 weeks = $964.4 )
Use inductive reasoning to predict the most probable next number in the list. 1, 4, 9, 16, 25, ?
Answer:
36
Step-by-step explanation:
Starting with 4, 9.
9 - 4 = 5 then + 2
So forward.
Answer:
1, 4, 9, 16, 25, 36
Step-by-step explanation:
This is because as you see 1 + 3 = 4, then 4 + 5 = 9, then 9 + 7 = 16. So we see that it goes like 3 + 5 + 7 + 9 + 11 + 13 . . . That is the pattern. Hope this helps!
Solve the rational expression 9x+3/12x+4
Answer:
The answer is
[tex] \frac{3}{4} [/tex]Step-by-step explanation:
[tex] \frac{9x + 3}{12x + 4} [/tex]
To solve the rational expression factorize both the numerator and the denominator.

9x + 3
Factorize 3 out
We have
3( 3x + 1)
For the denominator
12x + 4
Factorize 4 out
That's
4( 3x + 1)
So we now have
[tex] \frac{3(3x + 1)}{4(3x + 1)} [/tex]Reduce the expression with (3x + 1)
We have the final answer as

The height of an object tossed upward with an initial velocity of 120 feet per second is given by the formula h = −16t2 + 120t, where h is the height in feet and t is the time in seconds. Find the time required for the object to return to its point of departure.
Answer:
7.5 seconds
Step-by-step explanation:
[tex]h = - 16 {t}^{2} + 120t \\ \because \: we \: have \: to \: find \: the \: time \: required \: \\ for \: the \: object \: to \: return to \: its \: \\ point \: of departure. \\ \therefore \: plug \: h = 0 \: in \: the \: given \: euation. \\ \therefore \: 0 = - 16 {t}^{2} + 120t \\ \therefore \:16 {t}^{2} - 120t = 0 \\ \therefore \:8t(2t - 15) = 0 \\ \therefore \:8t = 0 \: \: or \: \: (2t - 15) = 0 \\ \therefore \:t = \frac{0}{8} \: or \: t = \frac{15}{2} \\ \therefore \:t = 0 \: or \: t = 7.5 \\ \because \: t = 0 \: is \: not \: possible \\ \huge \purple{ \boxed{ \therefore \: t = 7.5 \: seconds}}[/tex]
Thus, the time required for the object to return to its point of departure is 7.5 seconds.
The bus fare in a city is $ 1.75 People who use the bus have the option of purchasing a monthly coupon book for $ 35.00 With the coupon book, the fare is reduced to $0.50. How many times must someone use the bus so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book?
Answer:
28 times
Step-by-step explanation:
Create an equation where x represents the number of times the bus is used:
1.75x = 0.5x + 35
Solve for x:
1.75x = 0.5x + 35
1.25x = 35
x = 28
So, the bus has to be used 28 times for the prices to be the same.

cook books have recipes that are designed for 4 people. if a particular recipe in a cook book calls for 3 eggs, how many eggs would you need if you were cooking the recipe for 14 people?
Answer:
10.5
Step-by-step explanation:
If the recipe is designed for 4 people than you would need 6 eggs for 8 people (8 is twice as many as 4 so you need twice as many eggs.) similarly, 14 is 3.5 times as many as 4 (14/4=3.5) so you would need 3x3.5=10.5 eggs.

Answer:
The side of the square is 15m
The side of the triangle is 20m
Step-by-step explanation:
P square = 4s where s is the side length
P triangle = 3 x where x is the side length
x = s+5
The perimeters are equal
4s = 3x
Replace x with s+5
4s = 3(s+5)
Distribute
4s = 3s+15
Subtract 3s from each side
4s-3s = 15
s = 15
The side of the square is 15
x =s+5
=15+5
= 20
The side of the triangle is 20
Answer:
[tex]\Large \boxed{\mathrm{square: 15 \ meters}} \\\\ \Large \boxed{\mathrm{triangle: 20 \ meters}}[/tex]
Step-by-step explanation:
The perimeter of a square is [tex]\sf P=4s[/tex], where s is the side length.
The perimeter of an equilateral triangle is [tex]\sf P=3a[/tex], where a is the side length.
The side length of the equilateral triangle is 5 more than the side length of the square.
[tex]\sf a = s+5[/tex]
The perimeter of the square and equilateral triangle are equal.
[tex]\sf 4s=3(s+5)[/tex]
Expanding brackets.
[tex]\sf 4s=3s+15[/tex]
Subtracting 3s from both sides.
[tex]\sf s=15[/tex]
The side length of the square is 15 meters.
[tex]\sf a=15+5 \\\\\\ a=20[/tex]
The side length of the triangle is 20 meters.
Two fair dice are tossed and the number on each die is recorded, e.g. (3,2) indicates the first die had 3 and the second die had a 2. In total, there are 36 (equally likely) outcomes in the sample space. What is the probability the sum of the two dice is 7
Answer:
[tex]\dfrac{1}{6}[/tex]
Step-by-step explanation:
Given that two fair dice are tossed.
Total outcomes as we toss two dice are given as:
{
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
}
Where (a, b) represents a is the outcome of the die rolled for the 1st time and b is the outcome of 2nd toss of the die.
Total number of outcomes = 36
The outcomes with sum = 7 are :
{(1, 6), (2, 5), (3, 4) , (4, 3), (5, 2), (1, 6)}
Number of outcomes = 6
Probability of an event E is given as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
[tex]P(sum=7) = \dfrac{6}{36}\\\Rightarrow \bold{P(sum=7) = \dfrac{1}{6}}[/tex]

Which point lies on the line with point-slope equation y - 3 = 4(x + 7)?
A.
(7, 3)
B.
(7, -3)
C.
(-7, -3)
D.
(-7, 3)
Answer:
D. (-7, 3)Step-by-step explanation:
The standard form of a point slope equation of a line is expressed as shown;
y-y₀ = m(x-x₀) where;
m is the slope of the line
(x₀, y₀) is the coordinate of the point that lies in the line.
Comparing the standard equation given with the equation in question
y - 3 = 4(x + 7) to get the point on the line we will have;
y₀ = 3 and -x₀ = 7
for -x₀ = 7;
multiply both sides with a minus sign
-(-x₀) = -7
x₀ = -7
Hence the coordinate of the point required (x₀, y₀) is (-7, 3).
Alana noticed that a number like 8 = 2 (i.e. ) has exactly four factors: 1, 2, 2 , and ! 2 . What other numbers are of this form have exactly four factors? Do all the perfect cubes have exactly four factors? Is it true that all numbers that have exactly four factors are perfect cubes?
Answer:
Step-by-step explanation:
Hello,
What other numbers are of this form have exactly four factors?
[tex]8=2^3\text{ has 4 factors } 1, 2, 2^2, 2^3\\\\\text{For any prime p, }p^3\text{ has 4 factors } 1, p, p^2, p^3\\\\[/tex]
Do all the perfect cubes have exactly four factors?
[tex]\text{If p is not prime, then it is not true anymore} \\ \\\text{For instance, }8^3\text{ has more than 4 factors } 1, 2^2, 2^3, 2^4, etc..[/tex]
Is it true that all numbers that have exactly four factors are perfect cubes?
6 has 4 factors : 1, 2, 3, 6 but this is not a perfect cube.
Thank you.
We know that any number can be decomposed as a product of prime numbers.
For example:
[tex]8 = 1\cdot 2\cdot 2\cdot 2[/tex]
8 has four factors if we count the 1.
Now we need to answer some questions regarding this:
What other numbers are of this form have exactly four factors?
8 is a cube number.
Remember that all cube numbers X can be written as:
[tex]X = n\cdot n\cdot n \cdot 1[/tex]
Now, if n is prime, then we can say that X is of the form of 8 and also has 4 factors.
But let's see the case:
[tex]8\cdot 8\cdot8= 512[/tex]
512 is a perfect cube, and if we decompose it we get:
[tex]512 = 8\cdot 8\cdot 8 = (2\cdot 2\cdot 2)\cdot (2\cdot 2\cdot 2)\cdot (2\cdot 2\cdot 2)\cdot 1[/tex]
So we found a perfect cube that has 10 factors.
This means that not all perfect cubes have exactly 4 factors.
Now, all numbers that have exactly four factors are perfect cubes?
This is also false, just let's create a counterexample.
[tex]1\cdot 2\cdot 3\cdot 5 = 30[/tex]
the number 30 is not a perfect cube, and we can see that it has exactly 4 factors.

Answer:12
Step-by-step explanation:
100 points, will mark brainliest!!!! Explain why (4, 1) is not a solution to the equation y = 3x + 1.
Because if you substitute x = 4 and y = 1 in the equation of y = 3x + 1, you'll see that both sides are different.
So if we substitute x = 4 and y = 1 in the equation, we get:
1 = 3(4)+1
1 = 12+1
1 = 13
The equation isn't true though. Also we can explain why (4,1) isn't the solution to the equation by graph (you can go draw the graph of y = 3x + 1 and notice that the line doesn't pass through (4,1) )
Also how about another example? But this time, we use (0,1) which is the solution of y = 3x + 1.
Substitute x = 0 and y = 1 in the equation as we get:
1 = 3(0)+1
1 = 0 + 1
1 = 1
Since the equation is true, that means the (0,1) is one of the solution of y = 3x + 1.
Maybe, you want another example again? How about (1,4) which is also one of the solution of y = 3x + 1.
Again, substitute x = 1 and y = 4.
4 = 3(1)+1
4 = 3+1
4 = 4
Since the equation is true. Therefore (1,4) is also one of the solution of y = 3x + 1.
Also here's why (4,1) is not the solution of y = 3x + 1
Basically, from (x,y), 4 is the x and 1 is the y. If we substitute "x" in any equations, we get the "y". Meaning that the x value can be meant as "input" and we get the output "y" like Function which is it.
If we substitute x = 4 in the equation...
y = 3(4)+1
y = 12+1
y = 13
Meaning that the actual y value is 13, not 1. This explains why (4,1) isn't the right solution.
Maybe, what if we substitute y instead? Well that works. Now let's try substitute both y = 1 and y = 13 to see which is the right value.
(1) For y = 1,
1 = 3x+1
1-1=3x
0=3x
x=0 (Therefore, x = 0 and y = 1)
So the actual order is (0,1).
(2) For y = 13
13 = 3x+1
13-1 = 3x
3x = 12
x = 4 (Therefore, x = 4 and y = 13)
so the actual order for (2) is (4,13).
Basically, (4,1) is false for y = 3x + 1.
Answer:
See below
Step-by-step explanation:
Given the point (4,1) means
(x,y) = (4,1)
So, x = 4 , y = 1
Given the equation y = 3x+1
Put x = 4 and y = 1
=> 1 = 3(4)+1
=> 1 = 12 + 1
=> 1 ≠ 13
Since Left hand side doesn't equal right hand side, (4,1) is not the solution to y = 3x+1
