Answer: Melissa sleeps for 8 hours and wakes up at 7 am.
Step-by-step explanation: For this i was able to do just eliminate some answer. "Melissa sleeps for 7 hours and wakes up at 8 am," in this case Melissa would drink coffee because she slept less than 8 hours. "Melissa sleeps for 9 hours and wakes up at 5:30 am," in this case Melissa would drink coffee since she had woke up at 5:30 am. "Melissa sleeps for 7 hours and wakes up at 6 am," in this case Melissa would drink coffee since she had less than 8 hours of sleep. In conclusion, The only time Melissa wouldn't had drank coffee is when she had slept for 8 hours and woke up at 7 am. That is because had slept more than 8 hours and had woke up after 7 am.
Don buys a shirt for $24.85. His friend Daryl spends $3.15 more for his shirt. Sean paid the same price as Daryl for his shirt but bought 2. How much did Sean spend for his 2 shirts?
Solution
- Don buys a shirt for $24.85.
- Daryl spends $3.15 more for his shirt. This means that Daryl spends
[tex]\$24.85+\$3.15=\$28[/tex]- Thus, Daryl spends $28 on his shirt.
- Sean paid the same price as Daryl, that is, he paid $28 for each shirt.
- Sean bought two shirts, thus, Sean spends:
[tex]\$28+\$28=\$56[/tex]Final Answer
Sean spends $56 on his 2 shirts
3. Solve the absolute inequality |2x + 3| < x + 6
Answer
The solution is
-3 < x < 3
Explanation
To solve an expression with the absolute value symbol. we obtain two solutions for it.
We first solve when the other side of the equation to the absolute value symbol has positive sign.
Then, we obtain another solution by setting that other side (the right-hand side) to negative. For equations involving inequality signs, the second solution usually changes the inequality sign.
| 2x + 3 | < x + 6
First solution
2x + 3 < x + 6
2x - x < 6 - 3
x < 3
Second solution
2x + 3 > -(x + 6)
2x + 3 > -x - 6
2x + x > -6 - 3
3x > -9
Divide both sides by 3
(3x/3) > (-9/3)
x > -3
So, the solution written together,
x > -3 and x < 3
together, it is
-3 < x < 3

Answer: 64
Step-by-step explanation:
Length x width x higth= volume
4 x 8 x 2 = 64
Answer:
4 cm
Step-by-step explanation:
First, find the volume of the rectangular prism.
4*8*2=32*2=64 cm^-3
Now, the formula for the volume of the cube is:
Volume = side ^ 3
We know the volume is 64 cm^3, so plug it in to the equation:
64 = side ^ 3
take the cube root of both sides
4 = side

We have to find the line equation of the function shown. We see that passes through the points:
[tex](0,2)\text{ and }(3,1)[/tex]For doing so, we will find the slope and the y-intercept. The slope is given by the expression:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]where (x₁,y₁) and (x₂,y₂) are two points of the line. In this case, replacing we obtain:
[tex]m=\frac{1-2}{3-0}=\frac{-1}{3}=-\frac{1}{3}[/tex]And thus, the slope is - 1/3. Now, for the y-intercept, we remember that when the x-coordinate is 0, the y-intercept is the y-coordinate.
As the line passes through the point (0,2), the y-intercept will be 2.
Putting those two together, the equation of the line will be:
[tex]\begin{gathered} y=mx+b \\ y=-\frac{1}{3}x+2 \end{gathered}[/tex]Please solve for x using steps 1/3x= 1/3+6/x
You have the following algebraic equation:
1/3x = 1/3 + 6/x
In order to solve the previous equation you first multiply both sides of the equation by x, thus, you can quit x denominators in the equation. Proceed as follow:
1/3x = 1/3 + 6/x multiply by x both sides
1/3 = x/3 + 6 multiply by 3 both sides
1 = x + 18 subtract 18 both sides
1 - 18 = x + 18 - 18
-17 = x
-17 = x is the same as x = -17. The solution to the given equation is x = -17.
The country of Latveria has a population of 11.2 million at the start of 1988, which grows at 4.4% per year.A) Write a recursive equation for the population of Latveria.B) Write an explicit equation for the population of Latveria.C) To the nearest tenth of a million, what is the population of Latveria at the start of 1994.
A) The recursive formula takes into account the previous term. For each term, the next term is expressed in respect to it
Looking at the given scenario, the popularion is increasing by 4.4%. This means that the common ratio is
1 + 4.4/100 = 1.044
Given that the initial population is 11200000, the recaursive formula or equation would be
[tex]\begin{gathered} f_n=\text{ 1.044}f_{n\text{ - 1}} \\ \text{where f}_1=\text{ 11200000} \end{gathered}[/tex]B) For the explicit formula, the general formula for a geometric sequence is
an = a1 * r^(n - 1)
a1 = first term = 11200000
r = common ratio = 1.044
The explicit equation would be
an = 11200000 * 1.044^(n - 1)
C) At the start of 1994, the number of terms, n = 7
We would find a7 by substituting n = 7 into the explicit equation. We have
a7 = 11200000 * 1.044^(7 - 1)
a7 = 11200000 * 1.044^6 = 14501770

How much grain can a farmer hold in this silo? Use π = 3.14.A. 2,093.3 ft³B. 11,513.3 ft³C. 9,420 ft³D. 12,560.2 ft³
To find out how much grain the farmer can hold we need to find the volume of the silo. The silo is made from a circular cylinder and half a sphere.
The volume of the cylinder is given by:
[tex]V=\pi r^2h[/tex]In this case r=10 and h=30, plugging this values in the equation above we have that the volume of the cylinder is:
[tex]\begin{gathered} V=(3.14)(10)^2(30) \\ V=9420 \end{gathered}[/tex]Hence the volume of the cylinder is 9420 cubic feet.
Now we need to find the volume ot half the sphere, the volume og an sphere is given by:
[tex]V=\frac{4}{3}\pi r^3[/tex]Plugging the radius we have that:
[tex]\begin{gathered} V=\frac{4}{3}(3.14)(10)^3 \\ V=4186.6 \end{gathered}[/tex]Now, we only need half this volume then the volume of the top of the silo is:
[tex]V=2093.3[/tex]Finally we add the volume of the cylinder and half the sphere, therefore the volume of the sylo is:
[tex]11513.3[/tex]and the answer is B.

1.064 x 10¹ is 15.2 times larger than the 7 x 10⁻¹. It is obtaining the taking ratio of the given number. Option B is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We'll apply division by splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
Let 7 x 10⁻¹ be x times the number 1.064 x 10¹.
The value of x is obtained by taking the ratio of 1.064 x 10¹ and 7 x 10⁻¹.
x = 1.064 x 10¹ / 7 x 10⁻¹
x = 15.2

Which graph represents the solution set of the system of inequalities-2x+y<_4 y>x+2
The graph of the solution set of the system of inequalities y > x + 2 and
- 2x + y ≤ 4 is shown in figure.
What is mean by Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequalities is,
⇒ y > x + 2
And, - 2x + y ≤ 4
Now,
The inequality is,
⇒ - 2x + y ≤ 4
Add 2x both side, we get;
⇒ - 2x + y + 2x ≤ 4 + 2x
⇒ y ≤ 2x + 4
And, The second inequality is;
⇒ y > x + 2
So, Plot the graph of the inequalities y ≤ 2x + 4 and y > x + 2.
We get the solution set of the system of inequalities.
Which is shown in figure.
Thus, The graph of the solution set of the system of inequalities y > x + 2 and - 2x + y ≤ 4 is shown in figure.

Together, Nora and Addison own 152 shares of stock. Nora has 4 less than three times Addison's amount. How many shares does each girl have?
Dora have 144 shares of stocks while Addison have 37 shares of stocks.
Let us say that Addison own X shares of stock.
According to the situation provided,
The number of shares of stocks own by Dora are 4 less than 3 times of the Stocks owned by Addison.
Stocks Owned by Dora = 3x - 4
The total shares of stocks are 152.
So, we can write the relation between the stocks as,
x + 3x - 4 = 152
4x - 4 = 152
The above formed relations between the stocks is in the form of linear equation in one variable. A linear equation has highest power of variable equal to 1 and only one variable.
Now, solving the equation further,
4x - 4 = 152
4x = 148
x = 37
The total numbers of stocks owned by Addison are 37.
Shares of stocks owned by Dora are 3(37)-4.
The share of stocks owned by Dora are 144.
