If y varies directly as x, and y is 180 when x is n and y is n when x is 5, what is the value of n?
18
Answer:
30
Step-by-step explanation:
y varies directly with x, so:
y = kx
When x = n, y = 180.
180 = kn
When x = 5, y = n.
n = 5k
Solve for k in the first equation:
k = 180 / n
Substitute into the second equation:
n = 5 (180 / n)
n = 900 / n
n² = 900
n = 30

Where do I plot those fractions
Answer:
plot decimal values
Step-by-step explanation:
One approach is to convert them to decimal using your calculator or long division:
3/4 = 0.75
7/9 ≈ 0.78
1/2 = 0.50
2/3 ≈ 0.67
Since the number line has 0.1 increments, you can place each value in between the right increments. For instance 3/4 you place between 0.7 and 0.8. You place it halfway because 0.75 is halfway between 0.7 and 0.8. It's ok to estimate the exact location in this case.

How is the graph of the parent function y=x^2 transformed to produce the graph of y=3(x+1)^2?
Answer:
Shift 1 units towards left and then stretch vertically 3 times.
Step-by-step explanation:
We are given that a parent function
[tex]y=x^2[/tex]
After transformation, we get a graph [tex]y=3(x+1)^2[/tex]
We have to find that how the parent function transformed to produce the graph of [tex]y=3(x+1)^2[/tex]
The parent graph is shifted 1 unit towards left by the rule of transformation
[tex]f(x)\rightarrow f(x+1)[/tex]
By applying this rule then, we get
[tex]y(x)=(x+1)^2[/tex]
Now, the parent function stretched vertically 3 times the previous graph by the rule
[tex]f(x)\rightarrow 3f(x)[/tex]
Apply this rule then, we get

Find and interpret the meaning of the x -interpret in this scenario
(10,0) the time it takes for the helicopter to reach the ground
(18,0) the time it takes the helicopter to take off
(10,0) the time it takes the helicopter to take off
(18,0) the time it takes for the helicopter to reach the ground
Answer:
18,0 the time it takes or the helicopter to reach the ground.
Step-by-step explanation:
if you look at the table, it slowly is decreasing, therefore it is going towards the ground.
Answer: The correct option is
(D) (18,0) the time it takes for the helicopter to reach the ground.
Step-by-step explanation: Given that the table shown in the picture gives the number of feet a helicopter flies above the ground as a function of time.
We are to find and interpret the meaning of the x -interpret in this scenario.
From the table, we note that
the graph of function f(x) will pass though the points (0, 18) and (2, 16).
So, the slope of the line graph of f(x) is
[tex]m=\dfrac{16-18}{2-0}=\dfrac{-2}{2}=-1[/tex]
Since the line passes through the point (0, 18), so its equation will be
[tex]y-18=m(x-0)\\\\\Rightarrow y-18=-1\timesx\\\\\Rightarrow y=-x+18.[/tex]
Now, to find x-intercept, we need to substitute y = 0 in the equation of the line.
So, at y = 0, we get
[tex]0=-x+18\\\\\Rightarrow x=18.[/tex]
Therefore, the required x-intercept is (18, 0) and is shows that the time taken by the helicopter to reach the ground is 18.
Thus, option (D) is CORRECT.
Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) os located at (-2,1). What is the distance from B to B'?
Answer:
The distance from B to B' is 5 units
Step-by-step explanation:
The complete question is
Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) and point A' is located at (-2,1). What is the distance from B to B'?
we know that
In a translation the figure maintains its dimensions and internal angles
so
AA'=BB'=CC'=DD'
The distance BB' is the same that the distance AA'
Find the distance AA'
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
we have
A(1,5),A'(-2,1)
substitute in the formula
[tex]AA'=\sqrt{(1-5)^{2}+(-2-1)^{2}}[/tex]
[tex]AA'=\sqrt{(-4)^{2}+(-3)^{2}}[/tex]
[tex]AA'=\sqrt{25}[/tex]
[tex]AA'=5\ units[/tex]
therefore
The distance from B to B' is 5 units

A few years ago. Sarah acquired a parcel of land valued at $16,500. Today, that same parcel of land has a value of $17.820. Find the percent increase in the property's
value. Round your answer to the nearest hundredth, if necessary.
Answer:
8%
Step-by-step explanation:
Use formula
[tex]\text{Percent increase}=\dfrac{\text{New value - Old value}}{\text{Old value}}\cdot 100\%[/tex]
Old value = $16,500
New value = $17,820
Hence, the percent increase is
[tex]\dfrac{\$17,820-\$16,500}{\$16,500}\cdot 100\%=\dfrac{\$1,320}{\$16,500}\cdot 100\%=\dfrac{8}{100}\cdot 100\%=8\%[/tex]
0.08 is equal to 8%, the percent increase in the value of the property is 8%.
First, calculate the increase in the value of the property:
increase = 17820 - 16500
= 1,320
Next, calculate the percent increase by dividing the amount of the increase by the original value of the property and multiply by 100%:
percent increase = (1320 / 16500) * 100
percent increase = 0.08
Since 0.08 is equal to 8%, the percent increase in the value of the property is 8%.

find the value of x and y. y=2x and 1.85x+3.7y=12.95
Answer:
x=1.4 y=2.8
Step-by-step explanation:
Lets substitute y with 2x. We get: 1.85x+7.4x=12.95.
Simplifying by combining x: 9.25x=12.95
Then you just divide 12.95 by 9.25: x=1.4
Now for y. We know why is 2x so we just have to multiply x by 2: y=2x, y=2.8.
3. Angle A in triangle ABC is obtuse. Can angle B or angle C be obtuse? Explain your reasoning
No, angle B or angle C can't be obtuse.
Step-by-step explanation:It is given that:
Angle A in triangle ABC is obtuse.
This means that:
∠A > 90°
Now, let us assume that:
Angle B is obtuse.
i.e. ∠B > 90°
Hence, we get that the sum of two angle is greater than 180 degree.(i.e. ∠A+∠B > 180° )
hence, the sum of all the three angles will be greater than 180 degrees.
But we know that in order to form a triangle the sum of all the three angles must be equal to 180 degree.
No, angle B and angle C cannot be obtuse if angle A is obtuse because the sum of angles in a triangle is always 180 degrees, and if one angle is obtuse, the other two must be acute to satisfy this rule.
We have,
In a triangle, the sum of all angles is always 180 degrees.
If angle A in triangle ABC is obtuse, it means it measures more than 90 degrees (greater than a right angle).
For the sum of the angles to be 180 degrees, angles B and C must be acute (measuring less than 90 degrees).
This is because if either angle B or angle C were obtuse, the sum of the angles would exceed 180 degrees, which is not possible in a triangle.
So, angle B and angle C cannot be obtuse if angle A is obtuse.
Thus,
No, angle B and angle C cannot be obtuse if angle A is obtuse because the sum of angles in a triangle is always 180 degrees, and if one angle is obtuse, the other two must be acute to satisfy this rule.

At noon, a tank contained 8 cm of water. After several hours, it contained 4 cm of water. What is the percent decrease of water in the tank?
The water level in the tank decreased from 8 cm to 4 cm. This represents a decrease of 4 cm or a 50% decrease.
Explanation:The decrease in water level in the tank is calculated by finding the difference between the initial level and the final level. In this case, the initial level is 8 cm and the final level is 4 cm. The difference between these two levels is 4 cm.
To calculate the percent decrease, divide the decrease in level by the initial level and then multiply by 100%. So, in this case, the percent decrease in water level is (4 cm / 8 cm) * 100% = 50%.
The percent decrease of water in the tank from noon to several hours later is therefore 50%.

The answers are B, C, and D.
Step-by-step explanation:
When you rotate an image 180° about the origin, you are flipping it twice. An easy rule is that an (x, y) pair becomes (-x, -y). Now just reverse the sign of the coordinates. Our rotated shape has the coordinates (-5, -6), (-5, -4), and (-8, -4).
Answer: C. (−5, −6) D. (−8, −4)

We know that the rule for rotation a shape by [tex]180^{\circ}[/tex] (counterclockwise or clockwise) is given by :-
[tex](x,y)\to(-x,-y)[/tex] [Polarity of coordinates gets changed]
Given : Troy drew a triangle with coordinates ( 5 , 6 ) , ( 5 , 4 ) , and ( 8 , 4 ) . He rotated the triangle 180° about the origin.
Then, the coordinates of the image will be :-
[tex]( 5 , 6 )\to(-5,-6)[/tex]
[tex]( 5 , 4 )\to(-5,-4)[/tex]
[tex]( 8 , 4 )\to(-8,-4)[/tex]
From the options, the coordinates of the image = (-5,-6) and (-8, -4)
Hence, option C and D are correct.
