Answer:
D: y = 3x
Step-by-step explanation:
The relationship shown is a proportion. The only "unknown" is the constant of proportionality, the slope of the line. That is most easily found by looking for the value of y that corresponds to the value x=1.

A farmer sells eggs in containers holding a dozen eggs. If he has 2178 eggs, how many containers will be filled completely? How many eggs will be left over?
Answer:
~181 containers filled completely, 6 eggs left over
Step-by-step explanation:
2178 ÷ 12 (a dozen, the number of eggs per container) = 181.5 containers
181 × 12 = 2,172 eggs
2,178 eggs - 2,172 = 6 eggs left over

Suppose that $500 is deposited into an account that pays 5.5% interest compounded
quarterly. How long will it take for the account to contain at least $1400? Round to the
nearest whole number.
Answer:
18.85 years
Step-by-step explanation:
Using the [tex]A=P(1+\frac{r}{n} )^{nt}[/tex] we can manipulate it to give us time.
However, let's identify our variables:
A is our final amount which is given to us, $1400.
P is our principle which is $500.
r is our rate which is 5.5% which can be traducted into 0.055.
n is the # of time our money get compounded per year, in this case quarterly means 4 times a year therefore n = 4.
t is time and is what we are trying to solve for.
Now let's manipulate our equation to find t:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
[tex]\frac{A}{P} =(1+\frac{r}{n} )^{nt}[/tex]
[tex]\frac{1400}{500} =(1+\frac{0.055}{4} )^{4t}[/tex]
[tex]2.8=1.01375^{4t}[/tex]
[tex]log_{1.01375}(2.8)=log_{1.01375}1.01375^{4t}[/tex]
[tex]log_{1.01375}(2.8)=4t[/tex]
[tex]\frac{log_{1.01375}(2.8)}{4} =t[/tex]
[tex]18.84876253=t[/tex]
It would take about 18.85 years in order for you to accumulate at least $1400.

represents "owing $26.00 is
better than owing $147.00.”
6.NS.7b
Answer:
See belowStep-by-step explanation:
Owing represent a negative balance.
So the inequality for this case is:
- 26.00 > - 147.00The word owing is given which simply denotes to negative transaction
So here the inequality is
-26.00>-147.00Or
-147.00<-26.00Find the Mean Absolute Deviation: {6, 6, 3, 4, 4}
Answer:
To find the mean absolute deviation take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set.

Answer:
144 sq cm
Step-by-step explanation:
The base is a triangle. Area of a triangle is:
A = 1/2 b • h
A = 1/2(4)•3
A = 6
There are 2 of these bases.
Area of 2 bases= 12.
There are three rectangular sides. Area of a rectangle is:
A = l × w (or b•h)
A = 5 × 11 = 55
A = 3 × 11 = 33
A = 4 × 11 = 44
Add up three rectangular faces and two bases for Total Surface Area:
12 + 55 + 33 + 44
= 144 sq cm
Answer:
144 cm ²
Step-by-step explanation:
The surface area of a right triangular prism is made up of 2 congruent triangles (these are called the "bases") and 3 rectangles.
Surface area of a right triangular prism formula
Surface area = (S₁ + S₂ + S₃)L + bh
where:
S₁, S₂ and S₃ are the side lengths of the triangleL is the length of the prismb is the length of the base of the triangleh is the height of the triangle⇒ Surface area = (3 + 4 + 5)11 + 4 × 3
= (12)11 + 12
= 132 + 12
= 144 cm²

A rectangle is graphed on a coordinate plane. The
coordinates for two of the vertices of the rectangle are
(-5, 8) and (-5, -6). What is the distance between
the two vertices?
The two vertices (-5, 8) and (-5, -6) of the rectangle have the same x-coordinates
The distance between the two vertices is 14 units
How to determine the distance between the two vertices?The vertices are given as:
(-5, 8) and (-5, -6)
The distance between the two vertices is calculated using:
d = √[(x2 - x1)^2 + (y2 - y1)^2]
So, we have:
d = √[(-5 + 5)^2 + (8 + 6)^2]
Evaluate the sum
d = √196
Evaluate the square root
d = 14
Hence, the distance between the two vertices is 14 units

NO LINKS!! Explain your answer (show the support by showing the changes in x and y on your table). If the relationship is linear, inverse or exponential, write the equation. #9
Answer:
relationship: inverseequation: y = 25/xStep-by-step explanation:
You are correct that the relationship is inverse, and that the product of x and y is a constant, 25.
__
The equation should be written so that y is a function of x:
[tex]\boxed{y=\dfrac{25}{x}}[/tex]
The x in the denominator clearly shows that y is proportional to the inverse of x.
Answer:
Linear relationship: increasing or decreasing one variable will cause a corresponding increase or decrease in the other variable.
Inverse relationship: the value of one variable decreases as the value of the other variable increases.
Exponential relationship: a constant change in the independent variable (x) gives the same proportional change in the dependent variable (y)
Question 5
As the x-value increases (by one unit), the y-value decreases.
Therefore, this is an inverse relationship.
The y-values can be calculated by dividing 25 by the x-value.

what’s the height of the cylinder? Is it 6? Or do i have to find it with the 17. Is it 10?
PLS HELP
Answer:
Cylinder height = 10
Semi-circle height = 3
Cone height = 4
Step-by-step explanation:
The height of the cylinder is always going to be the long side. 6 is the diameter of its circle. Here is a list of variables:
Diameter, D = 6
Radius, r = 3
Slant height of cone, c = 5
To find the height of the cylinder, we will need to find the height's of the cone and semi-circle:
CONE (see image attached)
a² + b² = c²
3² + h² = 5²
h² = 25 - 9
h = √16
h = 4
SEMI-CIRCLE
h = radius
h = 3
CYLINDER
Cylinder height = total h - semi-circle h - cone h
h = 17 - 3 - 4
h = 10

Carlos has 8 dollars and 48 cents. Alissa has 4 dollars and 14 cents. How much money does Carlos need
To give Alissa so that each of them has the same amount of money?
Answer:
.2 dollars and 17 cents
Step-by-step explanation:
Carlos has 8dollars and 48 cents --->8+0.48=8.48
Alissa has 4dollars and 14 cents--->4+0.14=4.14 let
x--->amount of money that Carlos needs to give Alissa
The linear equation that represents this situation is 8.48-x=4.14+x
solve for x2x=8.48-4.14
2x=4.34
x=2.17
therefore,the amount of money is 2 dollars and 17 cents.

a triangle banner is to be made according to the specifications in the figure shown with dimensions given in inches. WOODEN STICKS WILL BE USED TO OUTLINE THE PERIMETER of the banner in order to attach the interior material. How many inches of wooden sticks will be required?
Applying the Pythagorean theorem, the amount of inches of wood required = Perimeter of triangle = 15 + 13 + 9 = 37 inches.
What is the Pythagroean Theorem?The Pythagorean theorem is used to find a side of a right triangle, and it states that if c is the hypotenuse and a and b are the other legs, therefore: c² = a² + b².
Find the altitude/height of the triangle using the Pythagorean theorem:
height = √(13² - 5²)
height = 12
Also, use the Pythagorean theorem to find the missing side (part of the longest side of the main triangle):
missing side = √(15² - 12²) = 9
Amount of inches of wood required = Perimeter of triangle = 15 + 13 + 9 = 37 inches.

Which values are in the solution set of the compound inequality –8 < 3x + 7 ≤ 10? Select three options. –15 –5 –3 0 1
Answer:
Your answers: -5, 0, 1
Step-by-step explanation:
–8 < 3x + 7 ≤ 10 That is the original compount inequality given.
We need to solve it in order to get an easy option.
-15, -5, -3, 0, 1 are the options.
_________________________________________________
Steps to solve:
–8 < 3x + 7 ≤ 10
Subtract 7 from both sides
–8 < 3x ≤ 10 - 7
Now do 10-7
–8 < 3x ≤ 3
Do 3x divided by 3
–8 < x ≤ 1
________________________________________________________
Evaluation and Answer Explanation:
–8 < x ≤ 1
That is your inequality statement.
The inequality statement states that "x" is greater than -8 but less than or equal to 1.
We can automatically choose 0 and 1 because 0 is greater than -8 and less than or equal to 1.
1 is correct because it is greater than -8 and less than or equal to 1
Now, there are two answers remaining: -15; -5.
Let's try -15.
-15 isn't greater than -8 but is less than 1. This is incorrect because it follows one inequality but doesn't follow both.
**Rule: the bigger you go on the negatives like -20 or -99 your numbers get smaller. If you go more towards the 0 like -1, -5, -3 your numbers get bigger.
-5 works because it is greater than -8 and less than or equal to 1.
