The sale price of a trampoline before tax is $300 the sales tax is 4% find the sales tax in the total price of the trampoline
The trampoline will attract a sales tax of $12 which will take its total price to $312.
The trampoline costs $300 without taxes being accounted for yet.
The tax is 4%. In dollar terms this is:
= Sales tax percentage x Cost of trampoline
= 4% x 300
= $12
The total price of the trampoline will therefore be:
= Cost of trampoline + sales tax
= 300 + 12
= $312
In conclusion, the sales tax would be $12 and the total price would be $312.

Y+1=2/5(x+3) in standard form?
For this case we have that by definition, the equation of a line in the standard form is given by:
[tex]ax + by = c[/tex]
According to the statement we have the following equation of the line:
[tex]y + 1 = \frac {2} {5} (x + 3)[/tex]
We manipulate algebraically to write in the standard form. To do this we follow the steps below:
We apply distributive property on the right side of the equation:[tex]y + 1 = \frac {2} {5} x + \frac {6} {5}[/tex]
We subtract [tex]\frac {6} {5}[/tex] on both sides of the equation:
[tex]y + 1- \frac {6} {5} = \frac {2} {5} x\\y- \frac {1} {5} = \frac {2} {5} x[/tex]
We multiply by 5 on both sides of the equation:
[tex]5y-1 = 2x[/tex]
We subtract 5y on both sides of the equation:
[tex]2x-5y = -1[/tex]
Finally, the equation in its standard form is:
[tex]2x-5y = -1[/tex]

1. What is the percent change from 1000 to 80?
2. What is the percent change from 45 to 63?
3. What is the percent change from 250 to 60?
4. What is the percent change from 60 to 99?
Step-by-step explanation:
1.-92%
2.40%
3.-76%
4.65%
The percent changes for each scenario is: 1. From 1000 to 80: -92% 2. From 45 to 63: +40% 3. From 250 to 60: -76% 4. From 60 to 99: +65%.
To calculate the percent change between two values, we use the formula:
[tex]\[ \text{Percent Change} = \left( \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \right) \times 100\% \][/tex]
1. The percent change from 1000 to 80 is calculated as follows:
[tex]\[ \text{Percent Change} = \left( \frac{80 - 1000}{1000} \right) \times 100\% = \left( \frac{-920}{1000} \right) \times 100\% = -92\% \][/tex]
So, the percent change is a 92% decrease.
2. The percent change from 45 to 63 is calculated as follows:
[tex]\[ \text{Percent Change} = \left( \frac{63 - 45}{45} \right) \times 100\% = \left( \frac{18}{45} \right) \times 100\% = \frac{2}{5} \times 100\% = 40\% \][/tex]
So, the percent change is a 40% increase.
3. The percent change from 250 to 60 is calculated as follows:
[tex]\[ \text{Percent Change} = \left( \frac{60 - 250}{250} \right) \times 100\% = \left( \frac{-190}{250} \right) \times 100\% = -76\% \][/tex]
So, the percent change is a 76% decrease.
4. The percent change from 60 to 99 is calculated as follows:
[tex]\[ \text{Percent Change} = \left( \frac{99 - 60}{60} \right) \times 100\% = \left( \frac{39}{60} \right) \times 100\% = \frac{13}{20} \times 100\% = 65\% \][/tex]
So, the percent change is a 65% increase.

Step-by-step explanation:
Let y = f(x)
⇒y = |x+3|
When y is replaced by Y + k, the graph of y = f(x) shifts k units down
⇒ y replaced by Y + 5 translates the graph of y = f(x) 5 units down
∴ Y = g(x) is represented by Y + 5 = |x+3|
⇒ Y = |x+3| - 5

Now, to figure out our graph once in for all, we need to use the zero-interval test [test point [0, 0]] to ensure if we either shade the opposite portion [the portion that does NOT contain the origin] or the portion that DOES contain the origin. We then need to verify it as false or true:

∴ Height of First Copy = [tex]\frac{80}{100} \times \textrm{original height}= 0.8\times 25 cm = 20cm[/tex]
Hence Height of first copy is 20 cm
Now Another copy is reduce to 85% of First Copy.
Therefore to find the height of another copy can be find out by multiplying 85 with first copy height and then dividing by 100.
∴ Height of Another Copy = [tex]\frac{85}{100} \times \textrm{first copy height}= 0.85\times 20 cm = 17cm[/tex]
Hence Height of Another copy is 17 cm
Answer:
To find the height of the first copy,
multiply 0.8 by 25.
The height of the first copy is
20 cm.
To find the height of the second copy,
multiply 0.85 by the height of the first copy.
The height of the second copy is

a countey fair charges $7 and $0.75 for each ride token. you have $15 write a exspression that represents the amount (in dollars) you have left after entering the fair and purchasing n tokens. how many tokens can you purchase? how much money do you have after purchasing 6 tokens
Answer:
$3.50
Step-by-step explanation:
15.00 - 7.00 = 8.00
6 x .75 = 4.50
8.00- 4.5 = 3.50
The equation for the total amount for the fair and rides is given by the relation y = 0.75n + 7 where n is the total number of rides
The amount left after purchasing 6 tokens is $ 3.50
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 total amount be represented as = y
Now , the number of rides be = n
The cost of entry fee = $ 7
The cost for each ride = $ 0.75
The total amount available = $ 15
So , the equation will be
total amount = cost for each ride x number of rides + cost of entry fee
Substituting the values in the equation , we get
Total amount y = 0.75n + 7
y = 0.75n + 7
So , the equation is y = 0.75n + 7
Now , when purchasing 6 tokens , we get the remaining amount as
Substituting the value of n = 6 in the equation , we get
y = 0.75 x 6 + 7
y = 4.5 + 7
y = $ 11.5
So , the amount left = 15 - y
The total amount left = 15 - 11.5
The total amount left = $ 3.50
Hence , The equation for the total amount for the fair and rides is given by the relation y = 0.75n + 7 where n is the total number of rides
The amount left after purchasing 6 tokens is $ 3.50

A clothes line is connected from a window on one building to a window in a building across the alley. The clothesline is 10 yards long with an angle of depression of 17°. How far apart are the buildings?
Answer:
The distance between the two buildings is 9.563 yards.
Step-by-step explanation:
See the diagram attached.
AB and CD are two buildings AC distance apart.
Now, AC = ED.
The angle of depression of clothesline BD is 17 Degrees.
Now, given that BD = 10 yards.
And ∠ OBD = ∠ BDE = 17° {Alternate angles}
Now, from the right triangle Δ BED, we have
[tex]\cos 17 = \frac{ED}{BD} = \frac{ED}{10}[/tex]
⇒ ED = 10 cos 17 = 9.563 yards.
Therefore, the distance between the two buildings is 9.563 yards. (Answer)

2,319 rounded to hundreds
Answer:
2,300
Step-by-step explanation:
see attached to identify the hundreds digit.
How we round the hundreds digit depends on the number in the tens place.
If the number in the tens places is less than 5, then we keep the hundreds digit the same (i.e we round down)
If the number in the tens place is greater or equal to 5, then we increase the hundreds digit by 1 (i.e round up)
in this case, the digit in the tens place is 1 (i.e less than 5) hence we round down by keeping the hundreds place the same
we end up with 2,300
2,319 rounded to the nearest hundreds is 2,300.
To round the number 2,319 to the hundreds place, follow these steps:
Identify the hundreds place, which is the digit in the second position from the right. In 2,319, the hundreds place digit is 3.Look at the digit immediately to the right of the hundreds place, which is the tens place. In this case, it's 1.Apply the rounding rule: if the digit in the tens place is 5 or higher, round up. If it is lower than 5, do not round up. Since 1 is less than 5, we do not round up.Replace all digits to the right of the hundreds place with zeros. Thus, 2,319 rounded to the nearest hundreds becomes 2,300.Therefore, the answer is 2,300.
Find the solution to the equations.
3x - y = -4
x + y = 0
Answer:
( - 1, 1 )
Step-by-step explanation:
Given the 2 equations
3x - y = - 4 → (1)
x + y = 0 → (2)
Subtract y from both sides in (2)
x = - y → (3)
Substitute x = - y into (1)
- 3y - y = - 4, that is
- 4y = - 4 ( divide both sides by - 4 )
y = 1
Substitute y = 1 into (3)
x = - 1
Solution is (- 1, 1 )
The solution to the system of equations 3x - y = -4 and x + y = 0 is found by substitution, resulting in the solution set (x, y) = (-1, 1).
To find the solution to the equations 3x - y = -4 and x + y = 0, you can use the method of substitution or elimination. Since the second equation easily gives us y in terms of x (that is, y = -x), we can substitute this into the first equation.
Substitute y = -x into the first equation: 3x - (-x) = -4.
Simplify: 3x + x = 4x
hence, 4x = -4
Divide both sides by 4 to solve for x: x = -1.
Now substitute x = -1 into y = -x to find y: y = -(-1) = 1.
The solution to the system of equations is (x, y) = (-1, 1).

If the distance between Sydney and Goulburn is 200 km, find the average speed to
complete the journey in 2hr 30mins (hint: speed = distance/time).
Answer:
Average Speed to complete the journey = 80 km/h
Step-by-step explanation:
Given,
The distance between Sydney and Goulburn = 200 kilometer.
Time to complete the journey = 2 hour 30 minutes
Converting the time into minutes -
2 hour 30 minutes
= (2 x 60) minutes + 30 minutes
= 120 minutes + 30 minutes
= 150 minutes
We know, to determine average speed, we have to divide the distance by time.
Therefore, Speed = [tex]\frac{Distance}{Time}[/tex]
Speed = [tex]\frac{200 km}{150 minutes}[/tex]
Speed = 1.33 km/minutes
Speed = (1.33 km x 60) km/hour (To convert it to hour, we have to multiply by 60)
Average Speed per hour = 80 km/h

y ≤ −x − 4
-10<-1-5
-10<-6
Pair: (1,-10)
Answer:
(1, −10)Step-by-step explanation:
If we graph this system of inequalities, we could find the solution.
From the graph you can deduct that the only right answer is the last one (1,-10), because the area of solution is only for negative values of y.
Therefore, the right choice is the last one.
If you can't graph, you can try another method. If we replace the value in the system, it should satisfy it, that is, it should gives us a true result like 0<1 for example. Let's try
For x=1 and y=-10, we have
-10 ≤ 1 − 5
-10 ≤ −1 − 4
-10 ≤ -4
-10 ≤ -5
As you can see, the result is true, because -10 is less than -4 and -5, so that's the right answer.

Answer:
90°
Step-by-step explanation:
step 1
Find the measure of angle b
we know that
(m∠b+90°)=124° ----> by vertical angles
so
m∠b=124°-90°
m∠b=34°
step 2
Find the measure of angle c
(m∠c+124°)=180° ----> by supplementary angles (form a linear pair)
m∠c=180°-124°
m∠c=56°
step 3
Find the measure of angle a
m∠a=m∠c ----> by vertical angles
so
m∠a=56°
step 4
Find the value of m∠ a + m∠b
m∠a=56°
m∠b=34°
m∠ a + m∠b=56°+34°
m∠ a + m∠b=90°
