Answer:
Original : $437.416 Rounded to Nearest Cent : 437.42
Step-by-step explanation:
Turn 30% into a decimal which is 0.3. Now multiply 0.3 by 584.
0.3 x 584 = 175.2
Now you have to subtract the answer by the original price, $584.
584 - 175.2 = 408.8
Finnaly, you have to find the sales tax of $408.8. In order to find that, you have to convert 7% into a decimal which is 0.07, then multiply it by 408.8. Then you have to add 408.8 to the following answer.(You can change a percent into a decimal by doing the number divided by 100)
0.07 x 408.8 = 28.616
408.8 + 28.62 = 437.42
Here's your answer. I know I'm late.
The cost of the kit is $437.416
What is discount?A deduction from the usual cost of something, typically given for prompt or advance payment or to a special category of buyers.
Given that, Brandt is buying a new set of golf clubs for $584. If the clubs are on sale now for 30% off and sales tax is 7%, we are asked to how much will he pay in total,
The cost of golf kit will be,
= (100-30)% of 584 + 7% of (100-30)% of 584
= 70% of 584 + 7% of 70% of 584
= 408.8 + 28.616
= 437.416
Hence, the cost of the kit is $437.416

Answer:
350feetStep-by-step explanation:
We want to find the height between the helicopter and the submarine
let us use the water as reference
therefore the given information
helicopter= 100 feet about sea level.
submarine = 250 feet below the sea level.
Therefore the distance between the helicopter and the submarine is given as

A brick becomes dislodged from the top of the Empire State Building (at a height of 1250 feet) and falls to the sidewalk below. What is the position formula?
Answer:
Position s(t) = -16t² + 1250 ft
Step-by-step explanation:
Given that:
initial height h₀ = 1250 feet
and suppose the position function is given as:
-16t² + v₀t + h₀
here;
v₀ = initial velocity
t = time
Thus, the position formula can be expressed as:
Position s(t) = -16t² + 1250 ft because v₀ = 0 ft/s and h₀ = 1250 feet

A triangle has angle measures x + 15 , 3x − 35 , and 4x. Find the value of x
Using the knowledge of the total sum of the internal angles of a triangle, the value of x would be 25
Recall :
A + B + C = 180° (Sum of the internal angles of a triangle)Hence,
(x + 15) + (3x - 35) + 4x = 180
x + 15 + 3x - 35 + 4x = 180
8x - 20 = 180
8x = 180 + 20
8x = 200
x = 200 / 8
x = 25°

What is the relationship between the slopes of two parallel lines?
Answer:In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other.
Step-by-step explanation:
The slopes of two parallel lines are always equal.
How to find the slope of a line?The slope of a line can be calculated by taking the tangent ratio of the angle formed by it with the x axis.
The angle between two parallel lines is zero.
It implies that they form same angle with the x-axis.
Since, the slope of a line is define as the tangent of the angle made by it with x axis.
The slopes of the parallel lines will be equal.
Suppose the slopes of two parallel lines are m₁ and m₂.
Then, it can be written as m₁ = m₂.
Hence, the relationship between the slopes of two parallel lines can be written as m₁ = m₂.

The ratio of the number of marbles in the red bag to the number in the blue bag is 3 : 5
Two marbles are moved from the blue bag to the red bag, making the ratio 7 : 9.
How many marbles are there in total?
answer: 16
step by step explanation:
The total number of marbles = 32 marbles.
We have ratio of the number of marbles in the red bag to the number in the blue bag is 3 : 5. After that, two marbles are moved from the blue bag to the red bag, making the ratio 7 : 9.
We have to find out how many marbles are there in total.
Is the ratio a:b equal to [tex]\frac{a}{b}[/tex].Yes, a:b equals to [tex]\frac{a}{b}[/tex] - where ' a ' is called Antecedent and ' b ' is called Consequent.
Let the total number of marbles be x.
Let the number of marbles in the red bag be ' x ' and in blue bag ' y '.
According to question -
[tex]\frac{x}{y} =\frac{3}{5}[/tex]
5x = 3y
x = [tex]\frac{3y}{5}[/tex]
After the two marbles are moved from blue bag are moved into the red bag, then -
[tex]\frac{x+2}{y-2} =\frac{7}{9}[/tex]
9(x + 2) = 7(y - 2)
9x + 18 = 7y - 14
9x - 7y = -32
9 ([tex]\frac{3y}{5}[/tex]) - 7y = -32
[tex]\frac{27y}{5} - 7y =-32[/tex]
[tex]\frac{-8y}{5}=-32[/tex]
-8y = -32 x 5
y = 4 x 5
y = 20
Therefore -
x = [tex]\frac{3\times20}{5}[/tex] = 12
Hence, the total number of marbles = x + y = 20 + 12 = 32 marbles.

A printer is printing photos. For every 6 photos, the printer takes 2 minutes.
Complete the table below showing the number of photos and the time it takes to print them.
Answer:
Next to 6 is 9, next to 15 is 27, and next to 3 is 5
Step-by-step explanation:
If you imagine 6 photos for every 2 minutes as a fraction and simplify it, the answer to this would be 3 photos for every 1 minute (basically 3/1). By using this unit fraction, you'll see that you're supposed multiply the amount of minutes by 3, or you can divide the # of photos by 3.
For 3 mins, you multiply that by 3 to get 9 photos.
For 9 mins, you multiply that by 3 to get 27 photos
For 15 photos, you divide that by 3 to get 5 photos.

Simplify to get a quadratic equation.
Use the quadratic formula to find the values of x.
Step-by-step explanation:
The radical equation is expressed as:
[tex]\sqrt{x+3} - \sqrt{2x-1} = -2[/tex]
The following steps are to be followed to calculate x:
Step 1: Raise both sides of the equation to the power of 2.
[tex](\sqrt{x+3} - \sqrt{2x-1})^2 = (-2)^2\\x+3 - 2\sqrt{x+3}\sqrt{2x-1}+(2x-1) = 4\\ - 2\sqrt{x+3}\sqrt{2x-1}+x+3+2x-1 = 4\\ - 2\sqrt{x+3}\sqrt{2x-1}+3x+2 = 4\\ - 2\sqrt{x+3}\sqrt{2x-1} +3x-2 = 0\\[/tex]
Step 2: Raise both sides of the equation to the power of 2 again
[tex](-2\sqrt{x+3}\sqrt{2x-1})^2 = (2-3x)^2\\4(x+3)(2x-1) = (2-3x)^2\\[/tex]
Step 3: Simplify to get a quadratic equation.

How do you factor 1x^2+9x+2
Answer:
not factorable
Step-by-step explanation:
To factor a trinomial of the type x^2 + ax + b, you need to find two numbers that add to a and multiply to b.
You have 1x^2 + 9x + 2.
In this case, a = 9 and b = 2.
There are no two integers whose sum is 9 and whose product is 2, so this trinomial is not factorable.
Sam traveled 20 miles in 3 hours.
Sam walked part of the distance at a speed of 4 miles per hour.
Sam rode his bicycle for the remaining distance at a speed of 12 miles per hour.
How many hours did sam spend walking?
How many hours did sam spend biking?
The number of hours that Sam spends walking is 1 hour. And the number of hours that Sam spends biking is 2 hours.
What is speed?We know that the speed formula
Speed = Distance/Time
Let 'x' and 'y' be the time when he walks and when he biking. Then the equations are given as,
x + y = 3 ...1
4x + 12y = 20 ...2
From equations 1 and 2, then we have
4(3 - y) + 12y = 20
12 - 4y + 12y = 20
8y = 8
y = 1 hour
The value of 'x' is calculated as,
x + 1 = 3
x = 2 hours

At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music. If 210 sixth-grade students prefer hip hop music, how many sixth-grade students are at the school?
Answer:
350 6th grade students
Step-by-step explanation:
From the question
At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music.
Total number of sixth graders that love hip-hop = 210
Let the total number of students in the school be represented as: x
Hence,
60% × x = 210
60/100 × x = 210
Cross Multiply
60x = 210 × 100
x = 210× 100/60
x = 350 students.
Therefore, the total number of sixth graders is 350 .
