Answer:
a. [tex]\frac{5}8[/tex] cups of purple paints required.
b. [tex]\frac{5}8[/tex]
Step-by-step explanation:
Given that
Number of purple paints required with 8 cups of white paint = 5
To find:
a. Number of cups of purple paint needed to be added to 1 cup of white paint ?
b. Constant of proportionality.
Solution:
Answer a. We can use unitary method here to find the number of cups of purple paint that are to be added to 1 cup of white paint.
Let us use the given statement:
8 cups of white paint require = 5 cups of purple paint
Let us divide both sides by 8:
1 cup of white paint require = [tex]\frac{5}8[/tex] cups of purple paint
Answer b.
Constant of proportionality is nothing but the ratio of two numbers which are present in a proportion.
Here, the ratio between number of cups of purple paint and number of cups of white paint is:
5:8 or [tex]\frac{5}8[/tex].
so, the answer is: [tex]\frac{5}8[/tex]
3/2(6x+4)=12 im dumb help me
Answer:
The correct answer is x = 2/3.
Step-by-step explanation:
To solve this problem, the first step I would take is multiply both sides by 2. This will allow us to get rid of the fraction on the left side of the equation and make it easier to solve. This is modeled below:
3/2(6x + 4) = 12
3(6x +4) = 24
Next, we can use the distributive property on the left side of the equation to get rid of the parentheses.
18x + 12 = 24
Then, we can subtract 12 from both sides of the equation.
18x = 12
Finally, we can divide both sides by 18 and simplify.
x = 12/18 = 2/3
Therefore, the correct answer is x =2/3.

Show Calculator
Answer:
radius = 8 unitsStep-by-step explanation:
Circumference of a circle = 2πr
where
r is the radius
From the question
Circumference = 50.24 units
To find the radius substitute the value into the above formula and solve for the radius
That's
[tex]50.24 = 2\pi \: r[/tex]
Divide both sides by 2π
We have
[tex]r = \frac{50.24}{2\pi} [/tex]
r = 7.9959
We have the final answer as
radius = 8 unitsHope this helps you
Answer:
8 units
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
50.24 = 2 * pi * r
Using 3.14 to approximate pi
50.24 = 2 * 3.14 * r
50.24 = 6.28 r
Divide each side by 6.28
50.24/6.28 = r
8 = r

Can you write a rule for finding the output (absolute guessing error) given the input (a guess)?
Answer:
The rule for the plotted line is [tex]y = \left | x - 50 \right |[/tex]
Step-by-step explanation:
The coordinates when y = 0, x = 50
When y = 10, x = 60
Therefore, the slope = (10 - 0)/(60 - 50) = 1
The equation in slope and intercept form is y - 10 = 1 × (x - 60)
y = x -60 + 10 = x -50
y = x - 50
Also, we have
When y = 20, x = 30
y = 10, x = 40
Therefore, the slope = (10 - 20)/(40 - 30) = -1
The equation in slope and intercept form is y - 10 = -1 × (x - 40)
y = -x + 40 + 10
y = 50 - x
Therefore, when x < 50, y = 50 - x
When x > 50, y = x - 50
Which is equivalent to [tex]y = \left | x - 50 \right |[/tex]
The rule for the plotted line is [tex]y = \left | x - 50 \right |[/tex]

Shelly is buying shoes online and computes that she has enough money to buy 5.91 pairs of shoes.
How many pairs of shoes can she buy?
Answer:
5
Step-by-step explanation:
This is because she cannot buy 5.91 pairs of shoes and she doesn't have enough money to buy exactly 6, so you must round it down to 5.
She can buy a maximum of 5 shoes with her money.
What is the reasoning?The procedure of utilizing logical reasoning to analyze a condition to determine the best problem-solving approach for a particular issue, then using this approach to create and explain a resolution.
In another word, reasoning is a tricky but interesting problem in mathematics that required relations of variables to solve.
Given that,
Shelly has money to buy 5.91 pairs of shoes.
Now,
Shoes are a whole quantity it will never come in fractions or decimals.
So,
We need to write 5.91 either 5 or 6
Now,
If we write it 6 then we do have not sufficient money but if we write 5 then we have money although some amount will be left still, she can buy 5 shoes.
Hence "She can buy a maximum of 5 shoes with her money".

Explanation:
The graph goes uphill as you read from left to right over the interval 0 < t < 3. This means t is between 0 and 3. So the graph is increasing over this interval. The same applies for the interval 14 < t < 18 as well.
The graph goes downhill we we are between t = 3 and t = 14, so that's why the graph is decreasing on the interval 3 < t < 14.
The local min is the lowest point of the graph. For sine functions like this, they occur infinitely many often. But we're restricting to just one cycle (so to speak) and we only have one local min at (t, V) = (14, 1). So that explains the answer to part E. The answer to part D is similar but we're looking at the highest point this time at (3,7)
As for part F, it seems like your teacher made a typo because the graph is neither at the highest nor the lowest point when t = 18. The graph is right in the middle instead.

A triangle has side lengths of (1.4u+9.6)(1.4u+9.6) centimeters, (4.3u-9.9)(4.3u−9.9) centimeters, and (5.3v+1.8)(5.3v+1.8) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
5.7u+5.3v+1.5Step-by-step explanation:
Given a triangle with side lengths s1, s2 and s3, the perimeter of the triangle in centimetre is expressed as the sum of all the sides of the triangle i.e
Perimeter of a triamgle = s1+s2+s3
Given the sides of the triangle in question as (1.4u+9.6) centimeters, (4.3u-9.9)centimeters, and (5.3v+1.8) centimeters, the perimeter of the triangle will be the sum of all the functions as shown;
Let s1 = (1.4u+9.6)cm
s2 = (4.3u-9.9)cm
s3 = (5.3v+1.8) cm
Perimeter of the triangle = 1.4u+9.6 + 4.3u-9.9 + 5.3v+1.8
collect like terms
P = 1.4u+ 4.3u+5.3v+9.6-9.9 +1.8
P = 5.7u+5.3v+1.5
Hence the expression that represents the perimeter of the triangle is 5.7u+5.3v+1.5

Step-by-step explanation:
A line segment starts at the point (2,3) and ends at the point (6,11). Find the equation of the perpendicular bisector of the segment. Demonstrate that your answer is correct. Your equation must be written in slope intercept form.
1). Slope = (-2)
2). Midpoint = (2, -2)
3). Slope of the perpendicular bisector = (1/2)
4). Equation of perpendicular bisector will be x - 2y = 6
Step-by-step explanation:
A line segment has the endpoints at (4, -6) and (0, 2).
1). Then the slope of the given line segment will be = (y - y')/(x - x') = (2 + 6)/(0 - 4) = 8/(-4) = (-2)
2). Mid point of the line segment is given by
Therefore midpoints of the line segment will be = (2, -2)
3). Slope of the perpendicular bisector is represented by
⇒ (-2)×m2 = (-1)
⇒
4). Now we have to find the equation of perpendicular bisector passing through (2, -2) and slope (1/2).
Since standard equation of the line will be given as y = mx + c
passes through (2, -2).
c = (-1) - 2 = -3
Finally the equation of perpendicular bisector will be
⇒ 2y = x - 6
⇒ 2y - x = -6
⇒ x - 2y = 6
The lowest recorded temperature in a town was 4ºF, without the windchill. With the wind, the temperature felt like 10ºF below zero. On a number line, what is the distance between the two temperatures?
Given that the temperature of a town was 4ºF without the wind, and later 10ºF below zero with the wind, the distance between the two temperatures of the town on a number line is: 14 units.
The record of temperature of the town can be illustrated or plotted on a number line as shown in the diagram attached below.
The temperature of the town at 4ºF will be located 4 units away from point zero on the number line.
The temperature of the town at 10ºF below zero will be located 10 units away from point zero on the number line.
Thus the distance between these two temperatures will be:
4 units + 10 units = 14 units.Therefore, given that the temperature of a town was 4ºF without the wind, and later 10ºF below zero with the wind, the distance between the two temperatures of the town on a number line is: 14 units.

Given directed line segment QS , find the coordinates of R
such that the ratio of QR to RS is 3:5. Plot point R
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, what are the coordinates of point Q and R. But I would show how to solve this.
The location of a point O(x, y) which divides line segment AB in the ratio a:b with point A at ([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]) is given by the formula:
[tex]x=\frac{a}{a+b}(x_2-x_1)+x_1\\ \\y=\frac{a}{a+b}(y_2-y_1)+y_1[/tex]
If point Q is at ([tex]x_1,y_1[/tex]) and S at ([tex]x_2,y_2[/tex]) and R(x, y) divides QS in the ratio QR to RS is 3:5, The coordinates of R is:
[tex]x=\frac{3}{3+5}(x_2-x_1)+x_1=\frac{3}{8}(x_2-x_1)+x_1\\ \\y=\frac{3}{3+5}(y_2-y_1)+y_1=\frac{3}{8}(y_2-y_1)+y_1[/tex]
Let us assume Q(−9,4) and S(7,−4)
[tex]x=\frac{3}{8}(7-(-9))+(-9)=\frac{3}{8}(16)-9=-3\\\\y=\frac{3}{8}(-4-4)+4=\frac{3}{8}(-8)+4=1[/tex]
