Answer:
The independent variable is the cost of the item ([tex]d[/tex]), whereas the dependent variable is the change ([tex]c[/tex]) received by Darrel, since that quantity is calculated by subtracting the cost of the item from the value of the bill. The equation is the following linear equation: [tex]c = 20.00 - d[/tex]

If you roll a single six-sided die, what is the probability of rolling an odd number?
I am not sure but the probability could be 50% because there are 3 odd numbers on a die out of 6 and so half would be 50/100. Or 3/6.
Ana planted a garden with equal of roses daffodils and tulips. if she randomly selects a flower what is the probability that it is a lilly
Answer:
33.3%
Step-by-step explanation:
If all of them are equal out of 100%
that means Roses are 33.3 daffodils are 33.3 and lilly's are 33.3
a) 3∕5= 60∕100= 40% (resolvido) b) 11∕4= c) 4∕20= d) 9∕5= e) 10∕200= 5∕100= 5% (resolvido) f) 8∕200= g) 30∕300=
Answer:
En cada expresión queremos obtener 100 en el denominador.
Notar que en la primer eq. tendríamos:
a) 3/5 = (20/20)*(3/5) = (20*3)/(20*5) = 60/100 = 0.6 (corresponde a 60%)
b) 11/4 = ?
Acá el denominador es 4
tenemos que encontrar un número k tal que:
k*4 = 100
k = 100/4 = 25
Entonces podemos multiplicar denominador y numerador por 25.
11/4 = (25/25)*(11/4) = (25*11)/(25*4) = 275/100 = 2.75 (corresponde a 275%)
c) 4/20
el denominador es 20, entonces tenemos que resolver:
20*k = 100
k = 100/20 = 5
multiplicamos denominador y numerador por 5:
(5/5)*(4/20) = (5*4)/(5*20) = 20/100 = 0.2 (corresponde al 20%)
d) 9/5
el denominador es 5, entonces debemos resolver:
5*k = 100
k = 100/5 = 20
Debemos multiplicar denominador y numerador por 20
(20/20)*(9/5) = (20*9)/(20*5) = 180/100 = 1.8 (corresponde a 180%)
e) 10/200 = 5/100 = 0.05 (corresponde al 5%)
f) 8/200
Se resuelve de similar forma al de arriba (que ya tenias resuelto).
Aca el denominador eso 200, entonces tenemos que tener:
200*k = 100
k = 100/200 = 1/2
Entonces multiplicamos numerador y denominador por 1/2
(1/2/1/2)*(8/200) = (8*1/2)/(200*1/2) = 4/100 = 0.04 (corresponde al 4%)
g) 30/300
aca el denominador es 300
Entonces:
300*k = 100
k = 100/300 = 1/3
Multiplicamos numerador y denominador por 1/3
(1/3/1/3)*(30/300) = (30*1/3)/(300*1/3) = 10/100 = 0.1 (corresponde al 10%)

A school day starts at 08:50 hrs. and ends at 15:00 hrs. There are two breaks. One lasting 20 minutes and the other 1 hour. How much time is devoted to school activities?
Answer:
4:50 hrs to school activities
Step-by-step explanation:
the entire school day 6:10 hrs (with breaks)
so if we remove the breaks (which are 1:20hrs in total) we'll have 4:50hrs.
the equation would be: (the time the full day is)-(the total of breaks)= the school activity time.
so: 6:10hrs-1:20hrs= 4:50hrs
there's your answer. 4:50 hrs
*just remember i am working in the hrs format meaning 60 mins= 1hrs*

A rectangular banner covers an area of 2 7/8ft2. The length of the banner is 3/4ft. What is the width of the banner in ft?
Answer:
Width of the rectangular banner is [tex]3\frac{5}{6}[/tex] ft.
Step-by-step explanation:
Area of the rectangular banner = [tex]2\frac{7}{8}[/tex] square feet
= [tex]\frac{23}{8}[/tex] square feet
Area of rectangle is given by,
Area = Length × Width
Length of the banner = [tex]\frac{3}{4}[/tex] feet
From the formula,
[tex]\frac{23}{8}=\frac{3}{4}\times W[/tex]
W = [tex]\frac{\frac{23}{8} }{\frac{3}{4} }[/tex]
= [tex]\frac{23}{8}\times \frac{4}{3}[/tex]
= [tex]\frac{23}{6}[/tex]
= [tex]3\frac{5}{6}[/tex] ft
Therefore, width of the rectangular banner is [tex]3\frac{5}{6}[/tex] ft

What would the measure of the third angle
equal?
Answer:
55
Step-by-step explanation:
180−43−82=55(angles of a triangle add upto 180)
What would the measure of the third angle equal?
Well given that all 3 vertices of a triangle are supposed to be a sum of 180*
Hence this information side E is 82* and side H is 43* and when added up they equal 125 so then you would subtract 180 - 125 = 55\
Therefore, side T = 55*

Which statement about the graphs is true? NEED HELP!
Graph A is a valid density curve because the part of the graph from 2 to 6 is below the horizontal axis.
Graph A is not a valid density curve because the part of the graph from 1 to 2 is above the horizontal axis.
Graph B is not a valid density curve because part of the horizontal axis has negative values.
Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.
Answer:
Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.
Step-by-step explanation:
A density curve is a graph that shows probability.
There are a few properties that those curves have:
The curves are normalized, which means that the area inside the curve is always equal to 1 (or the 100% of possibilities).
And the probabilities are always defined with positive numbers between 0 and 1, which means that we can not have a density curve with elements below the horizontal axis.
From this, we can conclude that graph A is not a density curve (but neither of the two given options for graph A are correct, then we can discard these).
Now let's look at graph B.
We can see that all points are above the horizontal axis, so that is good.
Now let's compute the area inside the curve.
We can see two triangles, remember that the area of a triangle of base b and height h is:
A = (b*h)/2
To calculate the base in the image, just take the difference between the rightmost vertex and the left vertex.
The base of the left triangle is b = (-3 - (-5)) = 2, and the height is h = 0.25
Then the area is:
A1 = (2*0.25)/2 = 0.25
The base of the right triangle is b = (3 - (-3)) = 6, and the height is h = 0.25
Then the area of this triangle is:
A2 = (6*0.25)/2 = 0.75
If add these areas, we get:
Total area = A1 + A2 = 0.25 + 0.75 = 1
Total area = 1
So we have an area under the curve equal to 1, which means that graph B is a valid density curve.
And the correct option is then:
Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.

which number line shows the solution to the inequality -2x-3> -11
The solution to the inequality is x is less than 4.
What is inequility ?
An inequality is a mathematical statement that expresses a relationship between two values or expressions that are not necessarily equal. Inequalities are often used in mathematics to compare values, express constraints or limitations, and solve problems involving ranges of values.
To solve the inequality -2x - 3 > -11, we can start by isolating the variable x.
-2x - 3 > -11
Add 3 to both sides:
-2x > -8
Divide both sides by -2 (and flip the inequality because we're dividing by a negative number):
x < 4
So the solution to the inequality is x is less than 4.

What is the solution to 4|0.5x – 2.5| = 0?
x = 1.25
x = 5
x = –1.25 or x = 1.25
x = –5 or x = 5
Answer:
B. X=5Step-by-step explanation:
To solve this problem, first, you have to isolate the value of x from one side of the equation.
[tex]\sf{4|0.5x-2.5|=0}[/tex]
First, divide by 4 from both sides of an equation.
[tex]\sf{\dfrac{4|0.5x-2.5|}{4}}=\dfrac{0}{4}[/tex]
Solve.
|0.5x-2.5|=0
0.5x-2.5=0
x=5

Point B has coordinates (4,1). The x-coordinate of point A is -4. The distance between point A and point B is 10 units. What are the possible coordinates of point A?
Given:
Point B has coordinates (4,1).
The x-coordinate of point A is -4.
The distance between point A and point B is 10 units.
To find:
The possible coordinates of point A.
Solution:
Let the y-coordinate of point A be y. Then the two points are A(-4,y) and B(4,1).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The distance between point A and point B is 10 units.
[tex]\sqrt{(4-(-4))^2+(1-y)^2}=10[/tex]
Taking square on both sides, we get
[tex](8)^2+(1-y)^2=100[/tex]
[tex](1-y)^2=100-64[/tex]
[tex](1-y)^2=36[/tex]
Taking square root on both sides, we get
[tex](1-y)=\pm \sqrt{36}[/tex]
[tex]-y=\pm 6-1[/tex]
[tex]y=1\mp 6[/tex]
[tex]y=1-6[/tex] and [tex]y=1+6[/tex]
[tex]y=-5[/tex] and [tex]y=7[/tex]
Therefore, the possible coordinates of point A are either (-4,-5) or (-4,7).
