If a house has decreased 35% since it was purchased and it currently values 117,000 what was purchase value
Step-by-step explanation:
that means the current value of $117,000 is 100 - 35 = 65% of the original price.
65% = $117,000
1% = 65%/65 = 117000/65 = $1,800
100% = 1%×100 = 1800×100 = $180,000

Step-by-step explanation:
A boat is purchased for $51,000 and has a resale value of $42,000 after a useful life of 6 years. Using a book value depreciation chart, calculate the number of years until the book value of the boat is $48,000.
The number of years until the book value of the boat is $ 48, 000, can be found to be 2 years
How to find the number of years ?To find the number of years till the book value of the boat is $ 48, 000, you first need to find the depreciation rate per year by the formula :
= ( Purchase price of boat - Resale value ) / Useful life
= ( 51, 000 - 42, 000 ) / 6
= 9, 000 / 6 years
= $ 1, 500 per year
In the first year, the value of the boat would depreciate to:
= 51, 000 - 1, 500
= $ 49, 500
In the second year, the value would depreciate to:
= 49, 500 - 1, 500
= $ 48, 000
It therefore takes 2 years for the book value to be $ 48, 000.

The graph shows the cube root parent function Which statement best describes the function?
Answer:
The graph of the cube root function is a continuous and smooth curve that starts at the point (0,0) and extends indefinitely in both the positive and negative directions on the x-axis. The graph increases as x increases from negative infinity to 0, and then decreases as x increases from 0 to positive infinity.
The graph has a vertical asymptote at x = 0, meaning that as x approaches 0 from either direction, the y-values of the points on the graph become very large. However, since the function is defined as the cube root of x, the function is not actually defined at x = 0, so the asymptote is not part of the graph.
The function is an odd function, which means that it is symmetrical about the y-axis. This means that if we were to reflect the part of the graph that is to the right of the y-axis over the y-axis, the resulting graph would exactly match the part of the graph that is to the left of the y-axis.
Overall, the graph of the cube root function is a smooth curve that starts at (0,0) and extends indefinitely in both directions on the x-axis, with a vertical asymptote at x = 0 and symmetry about the y-axis.

You need to give 250 mcg of adrenaline, and you have a 1 mL ampoule of 1:1000 adrenaline. How many mL do you want?
The volume of adrenaline you want is 0.25mL
How to determine the volume you wantFrom the question, we have the following parameters that can be used in our computation:
Amount to give = 250 mcg of adrenaline
Available = 1 mL of 1 : 1000 of adrenaline
The expression 1 mL of 1 : 1000 of adrenaline means that
1:1000 contains 1 mg in 1 mL (i.e. 1000 microgram/mL)
So, we have
Available = 1 mL * 1000 microgram/mL
Evaluate
Available = 1000 micrograms
This can be expressed as
Available = 1000 mcg
So, we have
Amount to give = 250 mcg of adrenaline
Available = 1000 mcg of adrenaline
When converted to mL, we have
Available = 1 mL of 1 : 1000 of adrenaline
Divide by 4
Amount = 1 mL of 1/4 : 1000/4 of adrenaline
Evaluate
Amount = 1 mL of 1/4 : 250 of adrenaline
This implies that
Amount = 1 mL of 1/4

What is the meaning of total sales?
Total sales revenue usually referred to as gross sales is the sum of the value of the products and services a company provides to its clients over the course of a given reporting period.
Given that Larry earns $840 per pay period, plus a commission of 8% on his sales.
Assume that Larry sale $x during the last pay period.
The total earn is 840 + 8% of x
= 840 + 0.08x
According to the question:
840 + 0.08x = 2,440.00
Subtract 840 from both sides:
0.08x = 2,440 - 840
0.08x = 1600
Divide both sides by 0.08
x = 1600/0.08
x = 20,000
The sales is $20,000.
7. Given that, Tom's bill at a local restaurant was $19.47. He leaves 15% of the total bill as a tip.

A. The line that passes through the given coordinates does not represent a proportional relationship because the line passes through the origin.
B. The line that passes through the given coordinates represents a proportional relationship because the line passes through the origin.
C. The line that passes through the given coordinates does not represent a proportional relationship because the line does not pass through the origin.
D. The line that passes through the given coordinates represents a proportional relationship because the line does not pass through the origin.
The correct statement regarding the linear function passing through the coordinates (2, 1), (3,3), (5,7), (6,9) is given as follows:
A. The line that passes through the given coordinates does not represent a proportional relationship because the line passes through the origin.
When does a linear function represents a proportional relationship?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the change in y divided by the change in x.b is the y-intercept, representing the value of y when x = 0.A linear function represents a proportional relationship if it has an intercept of zero.
For the points in this problem, when x increases by one, y increases by two, hence the slope is given as follows:
m = 2/1 = 2.
Hence:
y = 2x + b.
When x = 2, y = 1, hence the intercept b is given as follows:
1 = 2 + b
b = -1.
As the intercept is different of zero, this is not a proportional relationship, and option A is correct.

A triangle has dimensions 9ft by 12ft if you wanted to increase the size of the triangle by a scale factor of 10 over three what would the area of the new triangle be
The area of the new triangle is 600ft²
How determine the area of the new triangle?To increase the size of a triangle by a scale factor of 10/3, multiply each dimension of the triangle by 10/3.
The new dimensions of the triangle will be:
10/3 × 9ft = 30ft
10/3 × 12ft = 40ft
The area of a triangle is given by the formula A = 1/2 × b ×h,
where b is the length of the base and h is the height of the triangle.
Thus, the area of the new triangle will be:
A = 1/2 × 30 × 40 = 600ft²

Using the scale drawing shown in the image find the actual length of the truck
The actual length of the modeled truck is 20.4 feet.
What is a scale factor?The scale factor defines a variable in a ratio of two different measurements.
Sometimes drawings of large models are represented in a scale factor of a smaller unit.
Given, A model diagram of a truck and each gridline represent 1 cm distance.
Now, To find the length of this model we'll count the number of gridlines horizontally from two endpoints of the truck which is 12 gridlines hence 12 cm.
Also given that 1 cm is equal to 1.7 feet.
Therefore, The actual length of the truck is (1.7×12) feet.
= 20.4 feet.
So, the length of the truck is 20.4 feet.

The velocity of the train is given as follows:
900 m / min.
How to obtain the velocity of the train?To obtain the velocity of the train, we must understand the relation between velocity, distance and time, which is given as follows:
v = d/t.
In which the parameters are given as follows:
v is the velocity.d is the distance.t is the time.The train took a difference of 200 m in 15 seconds = 0.25 minutes, hence the difference in velocities is given as follows:
200/0.25 = 800 m / min.
(the difference in velocity is the distance covered divided by the time).
As Uncle Tony is walking at a rate of 100 m / min, the velocity of the train is calculated as follows:
