Answer:
Thus, the original price of the pair of shoes was $100.
Step-by-step explanation:
Percentages
After a 60% discount, the sale price is now valued at 100-60=40% of its original price.
If the sale price is $40, then the original price is calculated as
$40 / 40 * 100 = $100
Thus, the original price of the pair of shoes was $100.
Verify applying 60% discount:
$100 - 60*$100/100 = $40
Consider the equation 2y - 4x = 12
Which equation, when graphed with the given equation, will form a system with Infinitely many solutions?
-y-2x = 6
-y=2x = 12
y=2x+6
y=2x + 12
Answer:
y = 2x + 6 and 2y-4x=12 are the same line, so have infinitely many solutions.
Step-by-step explanation:
2y - 4x = 12
This is the same as y = 2x + 6
The solution is Option C.
The value of the equation is y = 2x + 6
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
2y - 4x = 12 be equation (1)
On simplifying the equation , we get
Adding 4x on both sides of the equation , we get
2y = 4x + 12
Divide by 2 on both sides of the equation , we get
y = 2x + 6
Hence , the equation is y = 2x + 6

A car traveling at 45 ft/sec decelerates at a constant 7 feet per second squared. How many feet does the car travel before coming to a complete stop
Answer:
s = 144.64 feet
Step-by-step explanation:
Given that,
The initial speed of a car, u = 45 ft/s
Deacceleration of the car, a = -7 m/s²
We need to find the distance covered by the car travel before coming to a complete stop. let it is d.
Final velocity, v = 0
Using the third equation of motion as follows :
[tex]v^2-u^2=2as\\\\s=\dfrac{v^2-u^2}{2a}\\\\s=\dfrac{0^2-45^2}{2\times (-7)}\\\\s=144.64\ \text{feet}[/tex]
So, it will cover a distance of 144.64 feet.

The populations P (in thousands) of a certain town in North Carolina, from 2006 through 2012 can be modeled by
P = 5.5e^kt,
where t is the year, with
t = 6
corresponding to 2006. In 2008, the population was 7000.
Find the value of k for the model. Round your result to four decimal places.
Use your model to predict the population in 2018. (Round your answer to the nearest person.)
Answer:
k= 0.8936P = 53198890Step-by-step explanation:
In 2008
t = 8P= 7000As per equation, P = 5.5e^kt
7000 = 5.5e^(8k)e^(8k) = 7000/5.5e^(8k) = 1272.7272ln e^8k = ln 1272.72728k = 7.14891k= 7.14891/8k= 0.8936In 2018, t= 18, k= 0.8936

The slope of the line will be 6 and its [y] - intercept will be 90. Refer to the graph attached for more clearance.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation y = Kx also represents direct proportionality. Here, K is called constant of proportionality. It is same as slope.
Given is the elevation [h] (in feet) of the balloon which is modeled by the function h(x) = 6x + 90, where [x] is the time (in seconds) since you first noticed the hot air balloon.
We have the following equation -
y = 6x + 90
Refer to the graph attached.
The line passes through the points (-15, 0) and (0, 90). So, the slope of the line will be -
m = 90/15
m = 6
AND
[y] - intercept will be 90.
Domain → (0, ∞) and range → (0, ∞) for ideal situations.
Therefore, the slope of the line will be 6 and its [y] - intercept will be 90.

A)$10.21
B)$14.61
C)$16.51
D)$20.21
Answer:
$20.21
Step-by-step explanation:
$35.55 - $3.15 = $32.40
$32.40 - $2.20 = $30.20
30.20 - $14.99 = $15.21
$15.21 + $5.00 = $20.21
The answer is D
$35.55 - $3.15 = $32.4 $32.4 - $30.2 $30.2 - $14.99 = $15.21 $15.21 + $5 = $20.21

If a car is traveling at 120 km/s within 120 min, what is its distance? (Remember: 60 seconds = 1 min. 120 km = 120,000 m) *
Answer:
[tex]d=864\times 10^6\ m[/tex]
Step-by-step explanation:
Given that,
Speed of a car, v = 120 km/s
It takes 120 minutes
v = 120000 m/s
t = 7200 s
We need to find the distance covered. Speed is given by :
v = distance/time
[tex]d=v\times t\\\\d=120000\ m/s\times 7200\ s\\\\d=864\times 10^6\ m[/tex]
So, the distance covered is [tex]864\times 10^6\ m[/tex].
compare the fraction 3/5 to 1/2
Answer:
1 / 2 is smaller than 3 / 5.
Step-by-step explanation:
Compare 1/2 and 3/5. 1 / 2 is smaller than 3 / 5. Steps for comparing fractions. Find the least common denominator or LCM of the two denominators: LCM of 2 and 5 is 10; For the 1st fraction, since 2 × 5 = 10, 1 / 2 = 1 × 5 / 2 × 5 = 5 / 10; Likewise, for the 2nd fraction, since 5 × 2 = 10, 3 / 5 = 3 × 2 / 5 × 2 = 6 / 10 Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
