The required number of green tiles is 48
Given that,
Sandy has 288 tiles and wants one-half of the tiles divided evenly into three different colors (green, yellow, burgundy), How many green tiles she need is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
total number of tiles = 288
half of the tiles = 288 / 2 = 144
Now this half number of tiles is divided into 3 equal parts, in (green, yellow, burgundy)
= 144 / 3
= 48
So, she needs 48 green tiles.
Thus the required number of green tiles is 48.

Which of the following could be a first step in correctly solving the equation below?
5(x-2)-2x=2
A.5(x-2)-2x+2=0
B.5(x-2)-2x=2-2x
C.5x-2-2x=2
D.5x-10-2x=2
The first step in solving the equation is to distribute the 5, making option D the correct choice, which results in 5x - 10 - 2x = 2.
Explanation:The first step in correctly solving the equation 5(x-2)-2x=2 would be to distribute the 5 into the parentheses of the left term. This action aligns with option D where the distribution results in 5x - 10 - 2x = 2. Doing so simplifies the equation and sets it up for further steps such as combining like terms and isolating the variable.
Julie is selling candy bars to raise money for new band uniforms. Candy bar X sells for $2 and candy bar Y sells for $3. Julie needs to sell at least three times more Y candy bars than X candy bars. She has at most 36 candy bars to sell. Which objective function can be used to find the profit P that Julie makes from selling the candy bars?
A) P = x + y
B) P = 36xy
C) P = 2x + 3y
D) P = 3x + 2y
Answer:
Answer is C [tex]P = 2x + 3y[/tex]
Step-by-step explanation:
Selling price of candy bar X =$2
Selling price of candy bar Y =$3
So if Julie sells x from X candy bars and y bars from Y candy bars,
Profit made from selling X candy bars = [tex]2\times x[/tex]
Profit made from selling Y candy bars = [tex]3\times y[/tex]
Therefore, assuming that there is no cost for the candy bars the profit by selling candy bars can be represented by the following objective function:
[tex]P = 2x + 3y[/tex]
Therefore, answer is C

What is the equation of the line that is parallel to the line y − 1 = 4(x + 3) and passes through the point (4, 32)?
A)y = –x + 33
B)y = –x + 36
C)y = 4x − 16
D)y = 4x + 16
The equation of line that is parallel to the line [tex]y-1=4\left({x+3}\right)[/tex] and passes through the point [tex]\left({4,32}\right)[/tex] is [tex]\boxed{{\mathbf{y=4x+16}}}[/tex] and it matches with [tex]\boxed{{\mathbf{OPTION}}\,{\mathbf{D}}}[/tex] .
Further explanation:
It is given that the equation of line is [tex]y-1=4\left({x+3}\right)[/tex] and passes through point [tex]\left({4,32}\right)[/tex] .
Rewrite the given equation [tex]y-1=4\left({x+3}\right)[/tex] as follows:
[tex]\begin{aligned}y-1&=4\left({x+3}\right)\\y-1&=4x+12\\y&=4x+12+1\\y&=4x+13\\\end{aligned}[/tex]
Now, compare the obtained equation of line [tex]y=4x+13[/tex] with the standard equation of line [tex]y=mx+b[/tex] .
[tex]\begin{aligned}m&=4\\b&=13\\\end{aligned}[/tex]
Therefore, the slope is [tex]4[/tex] .
It is given that both lines are parallel to each other so the product of slope must be equal.
[tex]{m_1}={m_2}[/tex] …… (1)
Substitute [tex]4[/tex] for [tex]{m_1}[/tex] in equation (1) to obtain the value of slope [tex]{m_2}[/tex] .
[tex]{m_2}=4[/tex]
Therefore, the slope is [tex]4[/tex] .
It is given that the line passes through point [tex]\left({4,32}\right)[/tex] .
The point-slope form of the equation of a line with slope [tex]m[/tex] passes through point [tex]\left({{x_1},{y_1}}\right)[/tex] is represented as follows:
[tex]y-{y_1}=m\left({x-{x_1}}\right)[/tex] …… (2)
Substitute [tex]4[/tex] for [tex]{x_1}[/tex] , [tex]32[/tex] for [tex]{y_1}[/tex] and [tex]4[/tex] for [tex]m[/tex] in equation (2) to obtain the equation of line.
[tex]\begin{aligned}y-32&=4\left({x-4}\right)\\y-32&=4x-16\\y&=4x-16+32\\y&=4x+16\\\end{aligned}[/tex]
Therefore, the equation of line is [tex]y=4x+16[/tex] .
Now, the four options are given below.
[tex]\begin{gathered}{\text{OPTION A}}\to y=-x+33\hfill\\{\text{OPTION B}}\to y=-x+36\hfill\\{\text{OPTION C}}\to y=4x-16\hfill\\{\text{OPTION D}}\to y=4x+16\hfill\\\end{gathered}[/tex]
Since OPTION D matches the solution that is [tex]y=4x+16[/tex] .
Thus, the equation of line that is parallel to the line [tex]y-1=4\left({x+3}\right)[/tex] and passes through the point [tex]\left({4,32}\right)[/tex] is [tex]\boxed{{\mathbf{y=4x+16}}}[/tex] and it matches with [tex]\boxed{{\mathbf{OPTION}}\,{\mathbf{D}}}[/tex] .

A normal distribution in which approximately 68% of the data values fall within one standard deviation of the mean behaves according to
Final answer:
The normal distribution in question behaves according to the Empirical Rule, which states that about 68% of the data falls within one standard deviation of the mean in a bell-shaped, symmetric distribution. This percentage changes to about 95% within two standard deviations and over 99% within three standard deviations.
Explanation:
A normal distribution in which approximately 68% of the data values fall within one standard deviation of the mean behaves according to the Empirical Rule. This is a key concept of descriptive statistics that applies specifically to bell-shaped, symmetric distributions. According to the rule, about 68 percent of the data lies within one standard deviation of the mean, about 95 percent lies within two standard deviations, and over 99 percent lies within three standard deviations.
For example, if a distribution has a mean (μ) of 50 and a standard deviation (σ) of 6, then approximately 68 percent of the values (x) would lie between 44 (50 - 6) and 56 (50 + 6). These points are one standard deviation away from the mean and correspond to the z-scores of -1 and +1, respectively. It is important to remember that this rule only applies when the distribution is perfectly bell-shaped and symmetric.
Miguel Rodriguez borrow 200 from his brother Julio to pay for books and tuition . He agreed to pay Julio 6!months with simple annual interest at 6.2% A)how much with the interest amount to ? B) what amount must Miguel pay Julio at the end of 6 months ?
To answer the problem, you must the formula in finding the interest and after that we will add it to the principal to get the future value.
The formula is: I = Prt
Interest = Principal x rate x time
= 200 x 0.062 x 6/12
= $6.2 is the interest for 6 six months.
Future Value = Principal + Interest
FV = 200 + 6.20
FV = $206.20 is the amount to be paid at the end of 6 months.

A car travels 2 1/3 miles in 3 1/2 minutes at a constant speed. Write an equation to represent the car travels in miles and minutes
Answer:
x = [tex]\frac{2}{3}\times t[/tex]
Step-by-step explanation:
We know the formula to represent the speed is,
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
If a car travels the distance = [tex]\frac{7}{3}[/tex] miles in [tex]\frac{7}{2}[/tex] minutes then the speed will be
Speed = [tex]\frac{\frac{7}{3}}{\frac{7}{2}}[/tex]
= [tex]\frac{7}{3}\times \frac{2}{7}[/tex]
= [tex]\frac{2}{3}[/tex] miles per minute
If the car travels x miles in t minutes then the equation to calculate the distance will be
[tex]\frac{2}{3}=\frac{x}{t}[/tex]
x = [tex]\frac{2}{3}\times t[/tex]
Therefore, the equation that represents the distance in terms of time will be
x = [tex]\frac{2}{3}\times t[/tex]

Dan bought 5 1/4 gallons of gas on Friday and 6 1/2 gallons of gas on Saturday. How many liters of gas did he buy? Assume 1 gallon = 3.8 liters.
Answer:
Dan bought 44.65 liters of gas.
Step-by-step explanation:
The gas Dan bought on Friday and Saturday in gallons is
[tex]5\frac{1}{4}+6\frac{1}{2}[/tex]
[tex]=\frac{21}{4} +\frac{13}{2}[/tex]
We collect LCM for the denominators,
[tex]=\frac{21+26}{4}[/tex]
[tex]=\frac{47}{4}[/tex]gallons
We now convert to liters using the relation,
[tex]1\:gallon=3.8\: liters[/tex]
Let [tex]\frac{47}{4}\:gallons=x\:liters[/tex]
Then,
[tex]x=3.8\times \frac{47}{4}[/tex]
[tex]x=\frac{38}{10}\times \frac{47}{4}[/tex]
[tex]x=\frac{19}{5}\times \frac{47}{4}[/tex]
[tex]x=\frac{893}{20}=44.65[/tex]
Therefore Dan bought 44.65 liters of gas.
