What is the sale price?In order to solve the given task, use the concept of percentage.
Regular price of the product = $150Percentage discount = 60%New price of the product = Regular price of the product - (Percentage discount × Regular price of the product)
= 150 - (60% × 150)

analyze the solution to the system to determine whether there is a catapult arm length that aiden and natalie can both use to launch their tennis balls the same distance. explain your reasoning.
There is no catapult arm length that Aiden and Natalie can both use to launch their tennis balls the same distance.
From the graph,
x axis represents the arm length of the catapult and the y axis represents the distance.
The point at which the catapult arm length that Aiden and Natalie can both use to launch their tennis balls the same distance is the intersecting point of the both line
The coordinates of the intersecting point = (-30, 90)
Here arm length represents -30, but the arm length cannot be a negative value
Therefore, there is no arm length that gives equal distance

recipe for sparkling grape juice calls for 1 1/2 quarts of sparkling water and 3/4 quart of grape juice, how much grape juice would you need for 15/4 quarts of sparkling water
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
15/8 quart of grape juice is needed for 15/4 quart of sparkling water.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The recipe for sparkling grape juice calls for 1(1/2) quart of sparkling water and 3/4 quart of grape juice,
This means,
1(1/2) quart of sparkling water = 3/4 quart of grape juice
3/2 quart of sparkling water = 3/4 quart of grape juice
Multiply 15/6 on both sides.
15/6 x 3/2 quart of sparkling water = 15/6 x 3/4 quart of grape juice
15/4 quart of sparkling water = 15/8 quart of grape juice
Thus,
15/8 quart of grape juice is needed for 15/4 quart of sparkling water.

find an equation of variation in which y varies directly as x and the following is true. yequals 21.25 when xequals 4.25
Answer:
y = 5x
Step-by-step explanation:
the equation of variation in which y varies directly as x is
y = kx ← k is the constant of variation
to find k use the given y = 21.25 when x = 4.25
21.25 = 4.25k ( divide both sides by 4.25 )
5 = k
y = 5x ← equation of variation
Linda was selling tickets for the school play. She sold 10 more adult tickets than children tickets and she sold twice as many senior tickets as children tickets. Find an expression for the total number of tickets sold by Linda.
Answer:X+(X+10)+(2X)
Step-by-step explanation:
Lets say X is the amount of children tickets sold.
So she sold some kid tickets and we get an X
So X
and then she sold ten more than X tickets to adults
So now we have
X+(X+10)
And then she sold twice as many senior tickets than kids tickets
so now we have

Answer:
The slope is -0.5, which indicates a negative correlation.
Step-by-step explanation:
y = mx + b
Is a slope-intercept form of the equation.
The y represents the distance of the line from the y-axis. (if u were to graph the problem)
M represents the slope of the line.
An the value of b is equal to y when x = 0
The equation that was given is y = 4.0 - 0.5x, which wasn't written the normal way, like y = mx + b, they just switched the spots from y = mx + b, to y = b + mx.
So the slope is the 0.5. (which is also -0.5)

A new car is purchased for 22600 dollars. The value of the car depreciates at 11. 5% per year. To the nearest tenth of a year, how long will it be until the value of the car is 5200 dollars?.
When the car is acquired for $22600 and depreciates at an 11.5% rate, it will take 6.7 years for its worth to reach $5200.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).
Here,
Cost of car=$22600
Rate of depreciation=11.5%
After n years, value of car=$5200
Annual depreciation expense=22600*11.5%
=$2599
Value of the Car = Purchase cost - (Annual depreciation expenses * n)
5200=22600-(2599*n)
2599n=22600-5200
2599n=17400
n=6.695
n=6.7 years
The number of years until the value of the car is 5200 dollars at depreciation rate of 11.5% when purchased at 22600 dollars will be 6.7 years.

The length of a rectangle is 5 more than twice the width. The perimeter is 130 in. What is the area?
Answer:
900
Step-by-step explanation:
l = 2w + 5
2(2w + 5) + 2w = 130
4w + 10 + 2w = 130
6w + 10 = 130
6w = 120
w = 20
l = 2(20) + 5
l = 40 + 5
l = 45
130 = 2(45) + 2(20)
130 = 90 + 40
130 = 130
A = l × w
A = 45 × 20
A = 900

How to find the angle of a triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.
The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
The exterior angle theorem is used to find the value of v.
Therefore,

The maximum volume of right circular cylinder of maximum volume that can be inscribed in a sphere of radius 70 cm will be 2640.4 m³.
How to find volume of Right Circular Cylinder?
Right cylinders are cylinders with axes that are perpendicular to the bases.
Volume of a Right Circular Cylinder= πr²h
where,
r = radius of the base
h = height of right circular cylinder
Maximum volume of right circular cylinder that can be inscribed in a sphere will be,
[tex]\pi r^{2} h-\frac{\pi }{4} h^{3}\\\\= \frac{4\pi r^{3} }{3\sqrt{3} }[/tex]

Create a graph of this situation.
Show that the equation (y = mx + b) of this graph equals an= -30 + (n - 1)5
The equation (y = mx + b) of this graph is equal to the equation for this arithmetic sequence aₙ = a₁ + (n - 1)d
How to calculate an arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this mathematical expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.For the 10th term, the equation for the arithmetic sequence is given by;
a₁₀ = a₁ + (n - 1)d
15 = a₁ + (10 - 1)d
15 = a₁ + 9d
For the 14th term, the equation for the arithmetic sequence is given by;
a₁₄ = a₁ + (n - 1)d
35 = a₁ + (14 - 1)d
35 = a₁ + 13d
Next, we would determine the common difference as follows;
a + 9d = 15
a + 13d = 35
-4d = -20
Common difference, d = -20/-4
Common difference, d = 5.
For the first term of this arithmetic sequence, we have;
a + 9d = 15
a + 9(5) = 15
a = 15 - 45
First term, a = -30
Finally, we would write an equation for the nth term of an arithmetic sequence as follows;

Let z = x + iy

So the point (x, y) is equidistant from (1, 0), (-1, 0) and (0, 1)
(0, 0) is the only point which is equidistant from (1, 0), (-1, 0) and (0, 1)
