1. What is the unit price for each detergent? Brand Size (oz) Price ($) Brand A: $ per ounce A 32 4.80 Brand B: $ per ounce B 48 5.76 Brand C: $ per ounce C с 128 17.92 2. Which detergent is the best buy?
To determine the unit price for each detergent, i.e. the price per ounce, you have to divide the cost of the detergent by the number of ounces the container has.
Detergent A
Has 32 ounces
Costs $4.80
The unit price can be calculated as:
[tex]\frac{4.80}{32}=0.15[/tex]Detergent A costs $0.15/ounce
Detergent B
Has 48 ounces
Costs $5.76
The unit price can be calculated as the quotient between the price and the amount of detergent:
[tex]\frac{5.76}{48}=0.12[/tex]Detergent B costs $0.12/ounce
Detergent C
Has 128ounces
Costs $17.90
Calculate the unit price by dividing the price by the number of ounces of the container:
[tex]\frac{17.90}{128}=0.139\approx0.14[/tex]Detergent C costs $0.14/ounce.
The best detergent to buy is the one that has the lower unit price, so to determine which one is it you have to compare their price per ounce.
In this case, detergent B has the lower price per ounce and thus it is the best detergent to buy.

4. Ash is three years older than ShawnCrystal is four times as old as Shawn. Oscaris twice as old as Ash. Altogether their agestotal 49. Find each person's age.
Shawn's age = 5 years
Ash's age = 8 years
Crystal's age = 20 years
Oscar's age = 16 years
Explanations:Let Ash's age be represented by A
Let the Shawn's age be represented as S
Let the Crystal's age be represented as C
Let Oscar's age be represented as O
Ash is three years older than Shawn
A = S + 3.....................(1)
Crystal is 4 times as old as Shawn
C = 4S................................(2)
Oscar is twice as old as Ash
O = 2A.................................(3)
Altogether, their ages total 49
A + S + C + O = 49 ...............(4)
First, to get Oscar's age in terms of Shawn's age, substitute equation (1) into equation (3)
O = 2 ( S + 3)
O = 2S + 6..................(5)
Substitute equations (1), (2), and (5) into equation (4)
(S + 3) + S + (4S) + (2S + 6) = 49
S + S + 4S + 2S + 3 + 6 = 49
8S + 9 = 49
8S = 49 - 9
8S = 40
S = 40 / 8
S = 5
Shawn's age = 5 years
To get Ash's age, substitute the value of S into equation (1)
A = S + 3
A = 5 + 3
A = 8
Ash's age = 8 years
To get Crystal's age, substitute the value of S into equation (2)
C = 4S
C = 4(5)
C = 20
Crystal's age = 20 years
To get Oscar's age, substitute the value of A into equation (3)
O = 2A
O = 2(8)
O = 16
Oscar's age = 16 years

The effect of both trains moving in opposite directions is the same that if one of them was stationary and the other one was moving at 65 + 72 = 137 mph.
Now, we know that distance = speed x time. Let's call the distance d and the time y
We would have:
[tex]d=137t[/tex]Using the distance we're given,
[tex]822=137t[/tex]Solving for t :
[tex]\begin{gathered} 822=137t \\ \rightarrow\frac{822}{137}=t \\ \Rightarrow t=6 \end{gathered}[/tex]It would take 6 hours for them to be 822 miles apart .
Excluding hydropower, U.S. power plants used renewable energy sources to generate 105 million megawatthours of electricity in 2007. By 2012, the amount of electricity generated had increased to 219 million megawatthours. Let x represent the time (in years) since 2007 and let y represent the number of megawatt hours (inmillions).Because time x is defined in years since 2007, 2007 corresponds to x = 0 and 2012 corresponds to x = 5. Fnd therate of change (slope) of the use of renewable energy sources between 2007 and 2012.
In order to calculate the rate of change, we just need to divide the difference in megawatt hours generated between 2007 and 2012 by the period of 5 years.
So we have that:
[tex]\text{rate}=\frac{219-105}{5}=\frac{114}{5}=22.8[/tex]So the rate of change is 22.8 millions of megawatt hours generated per year.

Exercise data
$ 1500
Interest rate = 0.07%= 0.07/ 100 = 0.0007
a) How much interest will Arielle pay for the statement for the month of May which
has 31 days?
Simple Interest=P×I×N
where:
P=principle
I=daily interest rate
N=number of days between payments
Interest= 1500 x (0.07/100) x 31 = $ 32.55
another way to write
Interest= 1500 x (0.0007) x 31 = $ 32.55
b)What is the balance that she owes?
Balance = P x ( 1 + I*t) where t= time.
Balance = 1500 x (1 + 0.0007*31)
Balance = 1500 x (1 + 0.217)
Balance = 1500 x (1 .217)
Balance = 1532.55
another way to solve
Balance = P + Interest
Balance = 1500 + 32.55
Balance = 1532.55

What type of sequence and how to write the explicit rule.
The Solution:
Given the sequence below:
[tex]26,18,10,2,\ldots[/tex]We are required to identify the type of sequence and to find the explicit rule for the given sequence.
Step 1:
To determine the type of sequence, we shall run the following check:
[tex]\begin{gathered} a_2-a_1=a_3-a_2\text{ then it is an Arithmetic sequence} \\ \text{ but if} \\ \frac{a_2}{a_1}=\frac{a_3}{a_2}\text{ then it is a Geometric sequence.} \end{gathered}[/tex]So,
[tex]\begin{gathered} 18-26=10-18 \\ -8=-8 \\ \text{ Then it follows that the sequence is an Arithmetic sequence.} \end{gathered}[/tex]Thus, the sequence is an arithmetic sequence.
Step 2:
To find the explicit rule, we shall use the formula below:
[tex]a_n=a_1+(n-1)d[/tex]In this case,
[tex]\begin{gathered} a_1=\text{ first term=26} \\ n=\text{ number of terms=?} \\ d=\text{ co}mmon\text{ difference=18-26=-8} \end{gathered}[/tex]Substituting these values in the formula, we get

An aquarium is 0.5 feet wide, 1.5 feet tall, and 2 feet long.The bottom is covered with gravel to a height of 3 inches.The tank will be filled with water to 3 inches below the top.How many gallons of water are needed to fill the aquarium?(Use 1 gallon = 0.134 ft.) Ignore any water that might seepinto the layer of gravel. Round to the nearest tenth.
Step 1: Find the base area of the tank.
The base of the tank is a rectangle of length 2 ft and width 0.5 ft.
Hence,
[tex]\text{ the base area of the tank }=2ft\times0.5ft=1ft^2[/tex]Step 2: Find the height of the water in the tank.
The height of the tank = 1.5ft
the height of the gravel = 3in = 3/12 ft = 1/4 ft
The water is 3 inches (= 1/4 ft) below the top of the tank.
Hence, we must have that
[tex]\begin{gathered} x+\frac{1}{4}+\frac{1}{4}=1.5 \\ x+0.25+0.25=1.5 \\ x+0.5=1.5 \\ x=1.5-0.5=1\text{ ft} \end{gathered}[/tex]Therefore, the height of the water in the tank is 1 ft.
Step 3: Find the volume of the water in the tank
[tex]\begin{gathered} \text{ the volume of the water is given by} \\ V=\text{ base area of the tank }\times\text{ height of the water} \\ \text{ Where V is the volume of the water} \end{gathered}[/tex]Therefore,
[tex]V=1ft^2\times1ft=1ft^3[/tex]Since 1 gallon is equivalengt to 0.134 ft³ then
[tex]V=\frac{1}{0.134}\text{gallons }=7.5\text{ gallons}[/tex]Hence, the number of gallons of water are needed to fill the aquarium is 7.5 gallons.

A desk is on sale for $380, which is 20% off the original price. Which equation can be used to determine theamount of money saved, s, in dollars, when purchasing this desk on sale?A s= 0.2(380)BS = (380 = 0.8) - 380Cs= (380 = 0.5) – 380D8 = (380 = 0.8)
Since the desk was 20% off, the price of $380 represents 80% of the original price.
Step 1. Define an expression to find the original price.
To find this original price, we divide the discounted price of 380 by the percentage it represents: 0.8 (we represent 80% in decimal form as 0.8)
[tex]380\div0.8[/tex]That expression represents the original price.

EXPLANATION
Given:
Point ( - 4, 1)
⇒x = -4 and y = 1
Perpendicular equation
3/4 x + y = -5/4
We need to re-write the above equation in the form y = mx + b
y = -3/4 x -5/4
Compare the above with y=mx + b where m is the slope and b is the intercept.
slope(m) = -3/4
Slope of vertical lines are inverse of one another.
This implies that the slpe of our new equation is:
[tex]m=\frac{-1}{m}=\frac{-1}{-\frac{3}{4}}=\frac{4}{3}[/tex]Next, is to find the intercept of the new equation.
We can find this by substituting m = 4/3 , x = -4 and y = 1 into y=mx + b and then solve for b.
That is;
[tex]\begin{gathered} 1=\frac{4}{3}(-4)+b \\ \\ 1=-\frac{16}{3}+b \\ \\ 1+\frac{16}{3}=b \\ \\ b=\frac{3+16}{3} \\ \\ b=\frac{19}{3} \end{gathered}[/tex]We can proceed to form the new equation by simply substituting the values of m and b into y=mx + b
Hence, the equation is:

With all expenses factored in, they make a total of $4125. How much, on average, is the band payed per bar gig? (assume they are paid the same amount per party this month as they were last month). Write 2 algebra equations then solve.
We have two cases. The first month, they played in 3 private parties that payed the same. They had a cost of $200 in travel and, in the end, they made $2500. Let "p" be the paid amount of each party. Since there were 3, they were payed 3*p. If we then substract their expenses of $200, we get the final amount, that should be equal to $2500.
In an equation, this is:
[tex]\begin{gathered} 3p-200=2500 \\ 3p=2500+200 \\ 3p=2700 \\ p=\frac{2700}{3} \\ p=900 \end{gathered}[/tex]So, each party payed $900.
In the second month, they worked on 5 bar gigs and 2 private parties. We already know that each private party pays $900, so, if "b" is the average amount they made in each bar gig, then "5b" will be the total they made in bar gigs and, adding the party amount, we have, in the second month:
[tex]5b+2p=5b+2\cdot900=5b+1800[/tex]The had $350 travel expenses, so we need to substract this and we should end up with the total they made, that was $4125:
[tex]\begin{gathered} 5b+1800-350=4125 \\ 5b+1450=4125 \\ 5b=4125-1450 \\ 5b=2675 \\ b=\frac{2675}{5} \\ b=535 \end{gathered}[/tex]Thus, on average, they were payed $535 per bar gig.
The points (2,11) and (6,33) form a proportional relationship. Find the slope of the line through the points. Then use the slope to graph the line.
The slope (m) of the line using the given coordinates is 11/2 and the equation of the slope is plotted on the graph.
What do we mean by slope?The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on a straight line, a slope can be determined using a variety of approaches.A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).So, the slope formula is:
m = y₂ - y₁/x₂ - x₁Now, put the values and calculate as follows:
m = 33 - 11/6 - 2m = 22/4m = 11/2So, the slope equation will be:
y = mx + by = 11/2x + bNow, plot the graph of the equation, taking b = 1.
(Refer to the graph attached below)Therefore, the slope (m) of the line using the given coordinates is 11/2 and the equation of the slope is plotted on the graph.
