(c) Yes, +4 more
Step-by-step explanation:
The problem statement is telling you the available quantity in pounds. The answer choices are expressing the difference in terms of packets. A conversion of units of measure is needed.
__
availablePatel has 8 pounds of seed, and he puts it into 1/2-pound packets. Each pound will fill two (2) half-pound packets, so he has enough for ...
(8 lb) × (2 packets/lb) = 16 packets
neededPatel has 12 people planting seed, so needs 12 of the 16 packets in order to give each team member one packet.
He has enough seed for this need, and enough for 16 -12 = 4 more packets than he needs.

Noah receives a 5$ discount each month on his cell phone bill because he signed up for an auto pay from his bank account over the last 8 months Noah has paid a total of 280$ for his cell phone bill. what would Noah be charged for his cell phone bill each month if he stopped using auto pay
Using proportions, it is found that Noah would be charged $40 each month for his cell phone bill each month if he stopped using auto pay.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
He paid a total of $280 during 8 months, hence the monthly amount he paid is given by:
M = 280/8 = $35.
Without the discount, he would have paid $5 more, hence Noah would be charged $40 each month for his cell phone bill each month if he stopped using auto pay.

A vertical shift of 4 up.
A horizontal shift of 4 to the right.
A vertical shift of 5 down.
A horizontal shift of 4 to the left.
Question 4
Answer: Choice B
A horizontal shift of 4 to the right.
========================================================
Reason:
Replacing x with x-4 basically means we're decreasing each input by 4 units.
What this does is move the xy axis 4 units to the left. If we held the function curve fixed in place as the xy axis moved like this, then it would give the illusion the function is moving 4 units to the right.

What is the Arithmetic Sequence?Arithmetic sequence is a sequence where each consequtive term has a common constant difference.
An arithmetic sequence, therefore, is defined by two parameters, viz. the starting term and the common difference.
The arithmetic sequence formula is;
aₙ = a + (n − 1)d,
where;
a is the first term
n is the position of the term in the sequence
d is the common difference
aₙ is the nth term of the sequence.
Our sequence is 10, 14, 18, 22 up to row 20.
Using the sequence formula;
[tex]a_{20} = 10 + (20 - 1)4.\\a_{20} = 10 + (19\times 4)\\a_{20}= 10 + 76\\a_{20}= 86.[/tex]
Thus, the number of seats in row 20 was 86 seats.

Put the following equation of a line into slope-intercept form, simplifying all fractions. 5x+6y=42
Answer:
[tex]y=-\frac{5}{6} + 7[/tex]
Step-by-step explanation:
Slope-intercept formula requires us to isolate the y variable. We can do this in just a couple of steps.
1) Move 5x from the left to the right side by subtracting 5x from both sides. This cancels out the 5x on the left side, and remember, what we do to one side we must do to the other to keep the equation balanced.
[tex]6y=-5x+42[/tex]
2) Divide both sides by 6. Again, we are cancelling out the 6 on the left but we must also divide on the right. This would mean dividing -5 and 42 by 6 to get:
[tex]y=-\frac{5}{6} + 7[/tex]
28. sylvia researched changes in the deer population in her state's parks during her lifetime
and found that population has been halved every 8 years.
she wrote the equation 4800(8) { = 600 and plans to solve fort to determine in how
many years it will take for the current population of 4800 deer to reduce to 600.
Using an exponential function, it is found that it will take 24 years for the current population of 4800 deer to reduce to 600.
What is an exponential function?An exponential function is modeled by:
[tex]y = ab^x[/tex]
In which:
a is the initial value.b is the rate of change, as a decimal.In this problem, considering the initial value of 4800, and that the population halves every 8 years, the equation is given by:
[tex]A(t) = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}[/tex]
The population will be of 600 when A(t) = 600, hence:
[tex]A(t) = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}[/tex]
[tex]600 = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}[/tex]
[tex]\left(\frac{1}{2}\right)^{\frac{t}{8}} = \frac{600}{4800}[/tex]
[tex]\left(\frac{1}{2}\right)^{\frac{t}{8}} = \frac{1}{8}[/tex]
[tex]\left(\frac{1}{2}\right)^{\frac{t}{8}} = \left(\frac{1}{2}\right)^3[/tex]
Hence:
t/8 = 3.
t = 24.
It will take 24 years for the current population of 4800 deer to reduce to 600.

14.35: a baseball league has nine teams. during the season, each of the nine teams plays exactly three games with each of the other teams. what is the total number of games played?
Answer:
One team must play 8 games 3 times equals 24 games
One team must play 24 games
But each game uses 2 teams so there are 12 games in all
Or 9 * 24 / 2 = 108 games
Check: If there were 3 teams then one team must play
2 games 3 times for a total of 6 times so the total of games played will be six for each team or 18 games, but each game uses 2 teams so the total of games is nine: 1-2, 2-3, 1-3 (each team has played its opponent once) - 3 * 3 = 9
T = number of teams in league
(T - 1) 1 team plays each other once
(T - 1) * T each team has played 1 game for entire league
(T - 1) * T / 2 total games to be played for 1 game each
G * (T - 1) * T / 2 where G is number of games
