Based on the ratio, 5¹/₂ : 1¹/₂, the unit rate can be found to be so the statement is TRUE.
How to find the unit rate?To find the unit rate of a ratio, you should divide the first number in the ratio by the second number in the ratio.
When given the ratio, 5¹/₂ : 1¹/₂, therefore, the unit rate is:
= 5¹/₂ ÷ 1¹/₂
= 11/2 ÷ 3/2
= 11/2 x 2/3
= 22 / 6
= 3.6667
= 3²/₃
In conclusion, the unit rate of 5¹/₂ : 1¹/₂ is 3²/₃.

Answer:
the standing line is the "Y line"
the line laying down is the "X line"
wherever the line touches on the y and x line is where it intercepts
for the x it intercepts at 25 since it touches the x line between 20 and 30
for the y line it intercepts at - 55 since it touches the y line in between - 50 and - 60
an object moves along a parabolic path defined by the equation in such a way that the y-value is decreasing at a constant rate of 2 units per second. at what rate is the x-coordinate changing when x
So the change of rate of x is -1/3 .
The Derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. Derivatives are a fundamental tool of calculus.
Given that object is decreasing at constant rate of 2 units per second so we have [tex]y = 2x^2 + 1[/tex]
[tex]\frac{dy}{dt} = 4x \frac{dx}{dt}[/tex]
given dy/dt = -2
when x = 3/2
-2 = 4(3/2) dx/dt
-2 = 6 dx/dt
dx/dt = -2/6
= -1/3
Hence the change of rate of x is -1/3 .

Solve for "x"
4 (2x (2x - 1) - 1 (2x - 1)) = 0
Answer:
x = 1/2 or 0.5
Step-by-step explanation:
4 • ((2x • (2x - 1)) - (2x - 1)) = 0
The rule says: To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (2x-1) and the exponents are :
1, as (2x-1), is the same number as (2x-1)1
and 1, as (2x-1) is the same number as (2x-1)1
The product is therefore, (2x-1)(1+1) = (2x-1)2
4 • (2x - 1)2 = 0
4.2 Solve : (2x-1)2 = 0
(2x-1) 2 represents, in effect, a product of 2 terms which is equal to zero
For the product to be zero, at least one of these terms must be zero. Since all these terms are equal to each other, it actually means: 2x-1 = 0
Add 1 to both sides of the equation :
2x = 1
Divide both sides of the equation by 2:
x = 1/2 = 0.500
Answer:
x = 1/2.
Step-by-step explanation:
4 (2x (2x - 1) - 1 (2x - 1)) = 0
(2x (2x - 1) - 1 (2x - 1)) = 0
(2x - 1) is common to both parts.
(2x - 1)(2x - 1) = 0
2x - 1 = 0
x = 1/2.

Step-by-step explanation:
a. How much do 4 dozen buttons cost?
It costs 6$ for 48 buttons
b. How many dozens of buttons can the organizers buy for $27?
the cost of 4 dozens of buttons will be $ 6 and the organizers can buy 216 buttons for $ 27.
We are given that:
Cost of 48 buttons = $ 6
48 buttons = $ 6
Divide both sides by 48:
1 button = $ 6 / 48 = $ 1 / 8
Now, the cost of 4 dozen buttons will be:
4 dozen buttons = 12 × 4 = 48
So, the cost will be 4 6 only.
For $ 27, the organizers can buy:
Number of buttons = 27 ÷ 1 / 8
Number of buttons = 27 × 8
Number of buttons = 216 buttons.
Therefore, the cost of 4 dozens of buttons will be $ 6 and the organizers can buy 216 buttons for $ 27.

Write an equation in slope-intercept form for this line.
Step-by-step explanation:
the slope-intercept form :
y = ax + b
"a" being the slope, "b" being the y-intercept (the y value when x = 0).
but we have the slope and a point.
so, we can start with the point-slope form and then transform it :
y - y1 = a(x - x1)
"a" is again the slope, (x1, y1) is the given point.
so, we have
y - 3 = 4(x - -4) = 4(x + 4) = 4x + 16
y = 4x + 19

two soccer players are warming up by kicking soccer balls at a goalie. the two players are located 10 yards apart, and the angle from each player to the goalie is 64° and 75°, respectively. what is the distance from the farthest soccer player to the goalie?
Using the law of sines, it is found that the distance from the farthest soccer player to the goalie is 14.723 yards.
Given,
The distance between the two players = 10yards
The angle from each player to the goalie is 64° and 75°, respectively
We have to find,
the distance from the farthest soccer player to the goalie.
In this problem, considering that the sum of the internal angles of a triangle is of 180º, the angle that the goalie makes with the players is given by:
∠A = 180-(∠B+∠C)
∠A = 41°
Using Sine rule
AC/Sin B = BC / Sin A
AC = 10yrd*Sin75°/Sin41°
AC = 14.723 yards
The farthest distance is of 14.723 yards.

percent of the 25 gift bags
does Kia still have to make?
The percentage of bags that Kia still has to make for the contest is 36 %.
We are given that:
Kia has to make 14 bags out of 25 bags.
Now, she has already made 5 gift bags.
The number of bags she still has to make = 14 - 5 = 9
Now ,we need to find the percentage of 9 from the total of 25 so to get the percentage of bags that Kia still has to make.
So, we get that:
Percentage = 9 / 25 × 100 %
Percentage = 9 × 4 %
Percentage = 36 %
Therefore, we get that, the percentage of bags that Kia still has to make for the contest is 36 %.

A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 28 feet more
than the length of the shortest side. Find the dimensions if the perimeter is 144 feet.
According to the solving the dimensions of the triangles are as follow:
a . 29
b. 58
c. 57
What is meant by dimensions?A mathematical space's dimension is defined informally as the smallest number of coordinates required to specify any point within it. Thus, a line has a dimension of one since only one coordinate is required to identify a point on it - for example, the point at 5 on a number line.
How many dimensions are contained within a triangle?2-D shapes really had no thickness and they can only be measured on two sides. Two-dimensional objects include the square, circle, rectangle, and triangle.
According to the given data:x=length of the shortest side
2x=length of another side
x+28=length of the third side
144=x+2x+x+28
144=4x+28
144-28=4x
116=4x
x=116/4
x=29 feet (one side)
Putting the value of x to find second side
2x=58 feet (second side)
x+28= 57 feet (third side)
the perimeter of the triangle = sum of all the sides
= 29+58+57
