A store sells packages of candy for $52. Each packet cost $4 to make and contains $48 flavored gum and candy.Rolando knows how much each candy cost per pound and knows how many pounds of each candy are packed in each package. Let x represent the amount of gum per pound in each package and y represent the amount of candy per pound in each package.Use the following equation to complete the questions: x+y=180.75x+5.25y+4=52how many pounds of candy are in a box?what is the price per pound for a piece of candy?what does the term 0.75x represents in the second equation?
Answers
Let:
x be the amount of gum in pounds in each package.
y be the amount of candy in pounds in each package.
Each box or package cost $52: a packaging that cost $4 and $48 in gum and candy.
The amount of candy (in pounds) in each package is shown in the equation:
[tex]x+y=18[/tex]As this is the sum of the amount of gum x and the amount of candy y, we can say that each package has 18 pounds of candy and gum.
Then, the following equation,
[tex]0.75x+5.25y+4=52[/tex]seems to be the total cost, as it results in 52, that is the total cost of the box. There is also a term with value 4, that corresponds to the packaginf cost.
The other terms represent the cost of the gum (0.75 * x) and the candy (5.25 * y).
We can read from this equation that the price per pound of the gum is 0.75, because it is the factor that multiply the amount x to calculate the cost.
In the same way, we can say that 5.25 is the price per pound of the candy, as it is the factor that multiplies y.
Answers
How many pounds of candy are in a box? 18 pounds
What is the price per pound for a piece of candy? 5.25 $/lb
What does the term 0.75x represents in the second equation? The second equation represents the sum of all the costs (gum, candy and packaging cost). The term 0.75x represents the cost of the gum, as it multiplies the price of the gum per pound (0.74 $/lb) and the amount of gum (x, in lb/package).

What is decimal and fraction?
Suppose there is a collection and a part of collection has to be taken. The part which is taken is called fraction. The upper part of the fraction is the numerator and the lower part of the fraction is the denominator.
Decimal numbers are those numbers which consist of an integer part and a fractional part.
Decimal are of two types-
Terminating decimals are those decimals which has finite number of figures after decimal point
Non terminating decimals are those decimals which has infinite number of figures after decimal point.
Here, the fraction needs to be converted to decimal

Answers
The lines in the graph represent the growth rate of two plants, the height is on the y-axis and the time is on the x-axis.
a)
If the plants growth represent an equation system, the solution of said system will be the point where both lines intersect. This point is arround x=7 weeks and y=39 centimeters, you can expres it as a ordered pair (7,39)
b)
This means that by the 7nth week both plants were 39 centimeters tall.
c)
Looking at the graph, the line corresponding to plant 2 is more inclined than the line of plant 1, this means that the growth rate (slope) of plant 2 is greater than the growth rate of plant 1.
The second plant grows faster than the first one.
3. A business account was opened with $225,000earning 6.25% interest compounded yearly. Whatis the balance in the account after 3 years? Howmuch interest is earned after 3 years?
Answers
Answer:
Balance = 269,897.15
Interest earned 44,879.15
Explanation:
The compound interest formula is
[tex]A=P(1+r)^t[/tex]where P is the principal amount, is the interest rate, and t is the time interval.
Now in our case, we have
P = $225,000
r = 6.25%/100
t = 3 years
therefore, the final amount is
[tex]A=225,000(1+\frac{6.25}{100})^3[/tex][tex]\boxed{A=\$269,879.15}[/tex]which is the balance earned in 3 years.
The interest earned is the final amount minus the initial amount
[tex]\begin{gathered} I=A-P \\ I=\$269,879.15-\$225,000 \end{gathered}[/tex][tex]\boxed{I=\$44,879.15}[/tex]which is the interest earned in 3 years.

Answers
The volume of a prism can be calculated by multiplying the area of the base of the prism times its height:
[tex]V=A\cdot h[/tex]On the other hand, the area of the base of a triangle can be found by multiplying 1/2 times its base times its height (don't confuse the height of the triangle with the height of the prism):
[tex]A=\frac{1}{2}b\times h[/tex]Substitute the values for the base of the triangle and its height to find the area of the base. Then, substitute the result for the area and the value of the height of the prism to find the volume of the triangular prism.
If the base of the triangle has a length of 5.4cm, and its height is 3.2cm, then:
[tex]\begin{gathered} A=\frac{1}{2}\times5.4\operatorname{cm}\times3.2\operatorname{cm} \\ =8.64cm^2 \end{gathered}[/tex]If the height of the prism is 6cm, then its volume is:

Beth had 1/3 hour to get ready for work.She spent 1/5 hour putting on makeup.How much time does Beth have left?Give your answer in simplest form.1 hourEnter
Answers
To find how much time Beth has left, substract the time she spends on make up to the time she had to get ready.
This means that you have to substract 1/5 hour, which is the time she spends in make up, to 1/3 hour which is the time she has to get ready. This is: 1/3-1/5.
Imagine that you spent certain time on doing any activity, then you have to substract that time you spent from the time you had to do all your activities and duties. That is exactly what happened with Beth, she had 1/3 hour, but she spent 1/5 on make up, she needs to substract that 1/5 hour spent to the total time she had to know how much time she has left.
This will be a substraction of not similar fractions, you solve it this way:
[tex]\begin{gathered} \frac{1}{3}-\frac{1}{5} \\ =\frac{1\cdot5-1\cdot3}{3\cdot5} \\ =\frac{5-3}{15} \\ =\frac{2}{15} \end{gathered}[/tex]Now, she has 2/15 hours left.

To Find -
Solution =?
Step-by-Step Explanation -
x - y + z = -3 ........(1)
x - y - z = -3 ..........(2)
5x - 5y + z = -15 .........(3)
So, from equation 1:
z = -3 -x + y
Now, put the value of z in equation 2 and 3:
x - y - (-3 -x + y) = -3
2x - 2y = -6
x - y = -3 ........(4)
5x - 5y + (-3 -x + y) = -15
4x - 4y = -12
x - y = -3 ......(5)
Now, on subtracting equations (5) and (6):
x - y -(x - y) = -3 - (-3)
x - x + y - y = 3 - 3
0 = 0

Directoins: consider the leading coefficient of each polynomial function. what is the end behavior of the graph? can check using graphing calculator or Desmos.10. F(x) = 4×over 3 - 3x
Answers
Concept
We can find the degree of a polynomial by identifying the highest power of the variable that occurs in the polynomial. The term with the highest degree is called the leading term because it is usually written first. The coefficient of the leading term is called the leading coefficient.
From the function
[tex]f(x)=4x^3\text{ - 3x}[/tex]Therefore,
The leading coefficient = 4
The degree = 3
Next, the end behavior of the function
The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. So, the sign of the leading coefficient is sufficient to predict the end behavior of the function.
Interpretations:
As x tends to positive infinity, f(x) tend to positive infinity
As x tends to negative infinity, f(x) tend to positive infinity

The total finance charges forone year were S303. How much did each computer cost before finance charges?Note that the ALEKS graphing calculator can be used to make computations easier.
Answers
Answer
Cost of desktop = $1750
Cost of laptop = $1900
Explanation:
Let the price of the desktop computer be x
Let the price of laptop computer be y
Laptop cost $150 more than desktop
Therefore, the cost of laptop y is given mathematically below
y= x + 150 ------------ equation 1
The interest rate of laptop is 9.5%
The interest rate of desktop is 7%
A sum of $303 was paid for the total financial charges
This statement can be represented mathematically as
0.07x + 0.095y = 303 ------------------ equation 2
Combine the two system of equations together and solve simultaneously
y = x + 150 ------------ equation 1
0.07x + 0.095y = 303 ---equation 2
Substitute the value of y in equation 2
0.07x + 0.095(x + 150 ) = 303
Open the parentheses
0.07x + 0.095x + 14.25 = 303
Collect the like terms
0.07x + 0.095x = 303 - 14.25
0.165x = 288.75
Divide both sides by 0.165
0.165x / 0.165 = 288.75 / 0.165
x = $1750
Find y
Since y = x + 150
x = 1750
y = 1750 + 150
y = $1900
Therefore, the cost of a desktop is $1750 and the cost of a laptop is $1900Answer
The point (7,-2) is a point on the graph of y=f(x)B) write the function that would shift (7,-2) right 3 then up 4
Answers
B) We have to find a function that would shift (7,-2) 3 units to the right and 4 units up.
To move a function in the horizontal axis, we have to add or substract the numbers of units in the argument:
f(x-k) will translate f(x) "k" units to the right. If "k" is negative, the function will be translated "k" units to the left.
Then, if we need to translate the point 3 units to the right, f(x) should have an argument of (x-3).
If we have to translate it in the vertical axis, we just add or substract outside f(x).
For example, f(x)+h will translate f(x) "h" units up. If "h" is negative, it will be translated down.
In this case, as we have to translate the function 4 units up, we add 4 outside of f(x).
Combining the two translations, we get:
[tex]y=f(x-3)+4[/tex]Answer:
B) The function that translates the function 3 units right and 4 units up is y = f(x-3)+4.

Success (x₂) = 220
Find: test statistic and p-value of this sample
Solution:
Based on the given data, we have two proportions here and its sample size is large. The test statistic that is appropriate for this would be Test of Two Proportions and the formula is:
[tex]z=\frac{p_1-p_2+cont\text{ }}{\sqrt[]{\frac{p(1-p)}{n_1}+\frac{p(1-p)_{}}{n_2}}}[/tex]in which,
[tex]p=\frac{x_1+x_2}{n_1+n_2}[/tex]Let's solve the value of p first. Let's plug in the given data that we have above.
[tex]p=\frac{122+220}{202+340}=\frac{342}{542}=\frac{171}{271}[/tex]Now that we have the value of p, let's calculate p₁ and p₂. Formula is:
[tex]\begin{gathered} p_1=\frac{x_1}{n_1}=\frac{122}{202}=\frac{61}{101} \\ p_2=\frac{x_2}{n_2}=\frac{220}{340}=\frac{11}{17} \end{gathered}[/tex]Lastly, let's calculate the value of cont or continuity correction. Formula is:
[tex]cont=\frac{F}{2}(\frac{1}{n_1}+\frac{1}{n_2})\text{ }[/tex]For our claim p₁ < p₂, our F = 1.
[tex]cont=\frac{1}{2}(\frac{1}{202}+\frac{1}{340})=0.0039458[/tex]Let's plug these values to the test of two proportions formula:
[tex]\begin{gathered} z=\frac{p_1-p_2+cont\text{ }}{\sqrt[]{\frac{p(1-p)}{n_1}+\frac{p(1-p)_{}}{n_2}}} \\ z=\frac{\frac{61}{101}-\frac{11}{17}+0.0039458}{\sqrt[]{\frac{\frac{171}{271}(1-\frac{171}{271})}{202}+\frac{\frac{171}{271}(1-\frac{171}{271})_{}}{340}}} \end{gathered}[/tex][tex]z=\frac{-0.03915259}{\sqrt[]{\frac{0.2328399668}{202}+\frac{0.2328399668}{340}}}=\frac{-0.03915259}{0.04286603008}\approx-0.913[/tex]Hence, the test statistic is -0.913.
The equivalent p-value for this is 0.1805.
The p-value is greater than α = 0.05.
Since p-value is greater than α, we fail to reject the null hypothesis.

[tex]\begin{gathered} K=6\times20-5=115 \\ J=20+8=28 \\ L=2\times20-3=37 \end{gathered}[/tex]7. Triangle MNQ is similar to triangle MOP. N 30 cm 9 cm M 0 12 cm P M M 24 cm Find the length of NQ. O A. 9.6 cm O B. 15 cm O C. 60 cm O D. 22.5 cm Please help!!! :( It is due today !!!

If the triangles MNQ and MOP are similar, then you know that the corresponding sides are at the same ratio. Because of this property, we can determine that:
[tex]\frac{MN}{MO}=\frac{MQ}{MP}=\frac{NQ}{OP}[/tex]We know the measure of the corresponding sides MQ=12cm and MO=24cm, and the measure of the corresponding side to NQ, using these measures we can calculate NQ as follows:
[tex]\begin{gathered} \frac{MQ}{MO}=\frac{NQ}{OP} \\ \frac{12}{24}=\frac{x}{30} \\ 30(\frac{12}{24})=x \\ x=15 \end{gathered}[/tex]Side NQ measures 15 cm
The correct option is B.

The given function is:
[tex]f(x)=x+3x+5[/tex]The domain is the set of all x-values for which the function is defined.
We can observe in this function, we don't have any restrictions on the domain, since the function is defined for any real number.
So, the domain is all real numbers.
