Solution:
Note that:
Given equation: y = 8xLet's substitute x as 2 to find out y.
y = 8x=> y = 8(2)=> y = 16Let's substitute x as 4 to find out y.
y = 8x=> y = 8(4)=> y = 32Final answer:
When x = 2, y = 16When x = 4, y = 32Option B is correct.
Find the value of x if mean of the given data is 4.5
5, 7, 7, 8, x, 5, 4, 3,1 and 2
Answer:
Step-by-step explanation:
First add what you have.
Sum = 5 + 7 +7+8 + x + 5 + 4 +3 + 1 +2
Sum = x + 42
Now when you divide this by the number of terms, you get
(x + 42) / 10
The answer is 4.5
(x + 42) / 10 = 4.5 Multiply by 10
x + 42 = 4.5 * 10
x + 42 = 45 Subtract 42
x = 45 - 42
x = 3

Solution:
We know that:
[tex]\bullet \ \ \tex\text{Area of triangle:} = \frac{1}{2} \times \tex\text{Base} \times \tex\text{Height}[/tex]
Let the base of the triangle be 11 yd. If we extend the base, it will allow us to find the height of the triangle, which is 8 yd.
Using the formula:
[tex]\bullet \ \ \tex\text{Area of triangle:} = \frac{1}{2} \times 11 \times 8[/tex]
Now, let's simplify.
[tex]\bullet \ \ \tex\text{Area of triangle:} = \frac{1}{2} \times 11 \times 8[/tex]
[tex]\bullet \ \ \tex\text{Area of triangle:} = 11 \times 4[/tex]

the perimeter of rectangular lawn is 300 m. if the length and breadth are in ratio of 8:7, find the area of the lawn
Answer:
5600 m²
Step-by-step explanation:
The perimeter of a rectangle is 2x + 2y = 300
If we have a ratio of length to breadth, we can just assign variables to simplify the problem. It doesn't matter if x is breadth or length and the same goes for y. But in this case, I just choose x as length and y as breadth.
x = 8n
y = 7n
2(8n) + 2(7n) = 300
30n = 300
n = 10
so, plugging n into x and y
x = 8(10) = 80
y = 7(10) = 70
Area of a rectangle
A = xy
A = (80)(70) = 5600 m²

Answer:
B. Shifted leftStep-by-step explanation:
Initial function is
f(x) = x²Changed function is
f(x + 8)This is best explained when graphed. See below to confirm the correct option
f(x+8)
(x+8)²So
x² is changed to (x+8)²

Find the value of x.
3x -8°
2x + 1°
If the angles are equal, then, x = 9.
What is simplification?Simplification of expressions means rewriting the same algebraic expression with no like terms and in a compact manner.
Given are two angles, 3x -8° and 2x + 1°, simplifying by equating them,
3x -8° = 2x + 1°
x = 9
Hence, If the angles are equal, then, x = 9.

Assume that in a local city it rains once every 7 days, on average. Also, assume that a full moon occurs once every 29 days. If we select a random date on the calendar, what is the probability that there will be rainfall and a full moon on that date.
The events of rainfall and having a full moon on a given date are illustrations of probability
The probability that there will be rainfall and a full moon on that date is 0.0049
How to determine the probabilityFrom the question, we have the following parameters
P(A) = 1/7 --- the probability that it rains
P(B) = 1/29 --- the probability of having a full moon
So, the probability that is rains and there is a full moon on a given day is:
[tex]p = \frac 17 * \frac 1{29}[/tex]
Simplify
[tex]p = 0.0049[/tex]
Hence, the probability that there will be rainfall and a full moon on that date is 0.0049

At 20 degrees celsius, the ice will melt in 20 minutes. How long will it take to melt in 30 degrees celsius?
Answer:
13.33
Step-by-step explanation:
Write the equation for an inverse variation
⇒ y = k/x
Where x is degrees and y is minutes
Substitute 20 and 20 for x and y
⇒ 20 = k/20
Multiply both sides by 20 to solve k
⇒ 20 × 20 = 20 × k/20
⇒ k = 400
After solving for k, write an equation for the inverse variation
⇒ y = 400/x
Substitute 30 for x
⇒ y = 400/30
⇒ y = 40/3
⇒ y = 13.3333333333
⇒ y = 13.33

Answer:
C
Step-by-step explanation:
Causation is when one thing causes another.
Correlation means one thing is related to another but doesn't cause it.
A - we know more rain means more rainfall which means more water in a river.
B - We know hotter temperature means things melt or evaporate faster.
C - This does not work. How does vision loss cause people to have hearing aids? There might be a correlation but it can't cause it.
D - We know fewer mistakes mean higher grades.
Which situation best demonstrates the phrase "correlation is not causation"?
O As rainfall increases, so does the water level in the river.
O The hotter the temperature, the faster ice will melt
O As the number of people with vision loss increases, the sale of hearing aids increases. ✓
In this case ,the correlation isn't causation because the sale of hearing aids hasn't increased because of increasement in vission loss cases but hearing aids cases but perhaps there's a correction of the sales of hearing aids and vision lossO The fewer mistakes a student makes on a math test, the better their grade is on the math test.

The epicenter of an earthquake is the point on Earth’s surface directly above the earthquake’s origin. A seismograph can be used to determine the distance to the epicenter of an earthquake. Seismographs are needed in three different places to locate an earthquake’s epicenter. Find the location of the earthquake’s epicenter if it is 3 miles away from (2,1) , 4 miles away from (5,-3) , and 5 miles away from (10,1)
Based on the calculations, the location of the earthquake’s epicenter is at (-1, 1).
What is an epicenter?An epicenter can be defined as the point on the surface of planet Earth, which is perpendicular to the hypocenter (focus) and directly above the earthquake’s origin. Also, it indicates where the seismic waves from an earthquake are most intense.
For this exercise, we would set the epicenter at x and y. Using the equation of a circle, we have the following:
At A (2, 1) and 3 miles away;
[tex](y-1)^2+(x-2)^2=3^2[/tex] ......equation 1.
At B (-5, 3) and 4 miles away;
[tex](y-3)^2+(x-(-5))^2=4^2\\\\(y-3)^2+(x+5)^2=4^2[/tex] ......equation 2.
At C (10, 1) and 5 miles away;
[tex](y-1)^2+(x-10)^2=5^2[/tex] ......equation 3.
Subtracting eqn. 2 from eqn. 1, we have:
[tex](x-2)^2-[(x+5)^2]=3^2-4^2\\\\x^2-2x-2x+4-[(x^2+5x+5x+25)]=9-16\\\\x^2-4x+4-x^2-10x-25=-7\\\\-14x-21=-7\\\\-14x=-7+21\\\\-14x=14\\\\x=\frac{-14}{14}[/tex]
x = -1 when y = 1.

Answer:
384sqrt3
Step-by-step explanation:
The formula for the area of a hexagon is A = 3sqrt3 times s^2 /2
Plug in s = 16 to get A = 3sqrt3 times 16^2 (256) / 2
3sqrt3 times 256 is 768sqrt3
You divide that by 2 to get 384sqrt3

Answer:
Given that measure 2 is 79 degrees, we know it'll be supplementary to angle 1 meaning that that both angle measures 1 and 2 will equal 180 degrees:
79 + x = 180
-79 -79
x = 101, ∠1 = 101°
Angles 2 and 4 are vertical, so they are congruent meaning they measure the same degrees:
if ∠2 = 79, then ∠4 is also equal to 79°
Now that we found the measure of angle 1, we can determine the measure of angle 3 since they are vertical as well, (vertical angles are congruent, meaning they measure the same degrees):
if ∠1 = 101, then ∠3 is also equal to 101°

The measure of angle x from the diagram is 102 degrees
Lines and anglesFrom the given diagram, we can see that the measure of angle "x" lies on the same line with 39 degrees. Since the sum of angles on a straight line is 180 degrees, hence;
39 + x + 39 = 180
78 + x = 180
Subtract 78 from both sides
78 + x - 78 = 180 - 78
x = 180 - 78
x = 102 degrees
Hence the measure of angle x from the diagram is 102 degrees
