Find the slope of a line perpendicular to the line whose equation is x + 6y = -24.
Fully simplify your answer.
Answer:
\(m_{perpendicular}\) = 6
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x + 6y = - 24 ( subtract x from both sides )
6y = - x - 24 ( divide through by 6 )
y = - \(\frac{1}{6}\) x - 4 ← in slope- intercept form
with slope m = - \(\frac{1}{6}\)
given a line with slope m then the slope of a line perpendicular to it is
\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-\frac{1}{6} }\) = 6
Jessica is in an art lesson. She decides to pick a coloured pencil from her pencil case at random for her next drawing.
She has 10 coloured pencils in her pencil case, and 8 of them are yellow. What is the probability, as a percentage (%), that she picks a yellow pencil?
The probability that Jessica picks a yellow pencil is 80%.
What exactly is probability?
Probability is a measure of an event's possibility or chance of occurring. It is stated as a number ranging from 0 to 1, or as a percentage ranging from 0% to 100%, where 0 indicates an impossible occurrence and 1 (or 100%) represents a certain event.
Now,
The probability of picking a yellow pencil = the number of yellow pencils / total number of pencils:
Probability of picking a yellow pencil = Number of yellow pencils / Total number of pencils
In this case, there are 8 yellow pencils out of a total of 10 pencils:
Probability of picking a yellow pencil = 8 / 10
Simplifying the fraction by dividing both the numerator and denominator by 2, we get:
Probability of picking a yellow pencil = 4 / 5
Probability of picking a yellow pencil = 4 / 5 x 100%
Probability of picking a yellow pencil = 80%
Therefore, the probability that Jessica picks a yellow pencil is 80%.

Emma and Ellie are twins and their birth weight can be compared using a scale of 0.75 pounds:0.9 pounds. If Emma weighed 6.4 pounds at birth, how much did Ellie weigh?
By comparism using the given scale ratio, the weight of Ellie at birth is 7.7pounds.
What is Ratio?Ratio simply compares values, it shows how much of one thing is related or compared to another thing.
Given the data in the question;
Scale of Emma SEmma = 0.75poundsScale of Emma SEllie = 0.9poundsWeight of Emma WEmma = 6.4poundsWeight of Ellie WEllie = XTo determine the weight of Ellie, we simply say;
0.75pounds : 0.9pounds = 6.4pounds : X
0.75pounds / 0.9pounds = 6.4pounds / X
Cross multiply
0.75pounds × X = 0.9pounds × 6.4pounds
0.75pounds × X = 5.76pounds²
X = 5.76pounds² / 0.75pounds
X = 7.68pounds
X = 7.7pounds
Therefore, by comparism using the given scale ratio, the weight of Ellie at birth is 7.7pounds.

Calculate the equivalent resistance Req of the network shown in Fig. 3.87 if R1 = 2R2 = 3R3 = 4R4 etc. and R11 = 3
The equivalent resistance of the network shown is: \(R_{eq}=16.463\Ohm\)
So, first of all, we can start by determining what each of the resistances is equal to. In this case we can start by saying that \(R_{1}=11R_{11}\) This means that:
\(R_{1}=11(3\Ohm)\)
Therefore:
\(R_{1}=33\Ohm\)
We can now use this value to find the value of the other resistances. The given condition for the resistances can be represented with the following formula:
\(R_{n}=\frac{R_{1}}{n}\)
so:
\(R_{2}=\frac{R_{1}}{2}=\frac{33}{2}\Ohm\)
\(R_{3}=\frac{R_{1}}{3}=\frac{33}{3}\Ohm=11 \Ohm\)
\(R_{4}=\frac{R_{1}}{4}=\frac{33}{4}\Ohm\)
\(R_{5}=\frac{R_{1}}{5}=\frac{33}{5}\Ohm\)
\(R_{6}=\frac{R_{1}}{6}=\frac{33}{6}\Ohm=\frac{11}{2}\Ohm\)
\(R_{7}=\frac{R_{1}}{7}=\frac{33}{7}\Ohm\)
\(R_{8}=\frac{R_{1}}{8}=\frac{33}{8}\Ohm\)
\(R_{9}=\frac{R_{1}}{9}=\frac{33}{9}\Ohm=\frac{11}{3}\Ohm\)
\(R_{10}=\frac{R_{1}}{10}=\frac{33}{10}\Ohm\)
\(R_{11}=3\Ohm\)
So now that we know what each resistance is equal to, we can go ahead and analyze the circuit.
In this case we can see that \(R_{10}\) and \(R_{11}\) are parallel, so we can calculate their equivalent resistance.
\(R_{1011}=\frac{R_{10}R_{11}}{R_{10}+R_{11}}\)
Which yields:
\(R_{1011}=\frac{(\frac{33}{10}\Ohm)(3\Ohm)}{\frac{33}{10}\Ohm+3\Ohm}\)
\(R_{1011}=\frac{11}{7}\Ohm\)
Now, \(R_{8}\), \(R_{9}\) and \(R_{1011}\) are connected in series, so we can calculate their equivalent resistance like this:
\(R_{891011}=R_{8}+R_{9}+R_{1011}\)
\(R_{891011}=\frac{33}{8}+\frac{11}{3}+\frac{11}{7}\)
\(R_{891011}=\frac{1573}{168}\Ohm\)
Now, we can see that \(R_{7}\) and \(R_{891011}\) are parallel, so we can calculate their equivalent resistance.
\(R_{7891011}=\frac{R_{7}R_{891011}}{R_{7}+R_{891011}}\)
Which yields:
\(R_{7891011}=\frac{(\frac{33}{7}\Ohm)(\frac{1573}{168})}{\frac{33}{7}\Ohm+\frac{1573}{168}\Ohm}\)
\(R_{7891011}=\frac{4719}{1505}\Ohm\)
Now, \(R_{5}\), \(R_{6}\) and \(R_{7891011}\) are connected in series, so we can calculate their equivalent resistance like this:
\(R_{567891011}=R_{5}+R_{6}+R_{7891011}\)
\(R_{567891011}=\frac{33}{5}\Ohm+\frac{11}{2}\Ohm+\frac{4719}{1505}\Ohm\)
\(R_{567891011}=15.236\Ohm\)
Next, we can see that \(R_{4}\) and \(R_{567891011}\) are parallel, so we can calculate their equivalent resistance.
\(R_{4567891011}=\frac{R_{4}R_{567891011}}{R_{4}+R_{567891011}}\)
Which yields:
\(R_{4567891011}=\frac{(\frac{33}{4}\Ohm)(15.236\Ohm)}{\frac{33}{4}\Ohm+15.236\Ohm}\)
\(R_{4567891011}=5.352\Ohm\)
Now, \(R_{2}\), \(R_{3}\) and \(R_{4567891011}\) are connected in series, so we can calculate their equivalent resistance like this:
\(R_{234567891011}=R_{2}+R_{3}+R_{4567891011}\)
\(R_{234567891011}=\frac{33}{2}\Ohm+11\Ohm+5.352\Ohm\)
\(R_{234567891011}=32.852\Ohm\)
Finally, we can see that \(R_{1}\) and \(R_{234567891011}\) are parallel, so we can calculate their equivalent resistance.
\(R_{eq}=\frac{R_{1}R_{234567891011}}{R_{1}+R_{234567891011}}\)
Which yields:
\(R_{eq}=\frac{(33\Ohm)(32.852\Ohm)}{33\Ohm+32.852\Ohm}\)
\(R_{eq}=16.463\Ohm\)

Point (4,-5)
Required
Determine the line equation
From the question, we understand that the line is parallel to \(y = -\frac{2}{3}x + 8\)
This implies that they have the same slope, m
A linear equation is:
\(y = mx + b\)
Where
\(m = slope\)
By comparison: \(y = mx + b\) and \(y = -\frac{2}{3}x + 8\)
\(m = -\frac{2}{3}\)
Next, we determine the line equation using:
\(y - y_1 = m(x - x_1)\)
Where
\((x_1,y_1) = (4,-5)\) and \(m = -\frac{2}{3}\)
\(y - (-5) = -\frac{2}{3}(x - 4)\)
\(y +5 = -\frac{2}{3}(x - 4)\)

simplify 38-87. I dont know
To check if we can simplify the fraction 38/87, we need to decompose the numerator and the denominator in their prime factors:
\(\begin{gathered} 38=2\cdot19 \\ 87=3\cdot29 \end{gathered}\)If the two numbers have any prime factor in common, we can divide both numbers by this prime factor. But in this case, the two numbers don't have prime factors in common, so we can't simplify the fraction further.
So the fraction 38/87 is already in the simplest fraction form.

Calculate the missing angles a, b, c, and d in the diagram below, giving a reason for each answer
Answer:
see below and attachment
Step-by-step explanation:
a=30°
because, the marked angle of 30° is an alternate interior angle to angle a. Alternate interior angles are congruent, and we know they are congruent because the 2 horizontal lines are parallel.
b=50°
because the marked angle of 50° is a vertical angle to angle b. Vertical angles are congruent because 2 lines that intersect have opposite congruent angles, making them vertical angles to each other.
c=50°
because the marked angle of 50° is a corresponding angle (same side angle) to angle c. These corresponding angles are congruent because the 2 horizontal lines are parallel.
d=100°
because the 3 interior angles of a triangle must add up to 180°. We have 30°, 50°, so the last angle must be 100°. We can also figure this out because the bottom horizontal line is a straight line, meaning the angle is also 180°. We have angle a as 30°, angle c as 50°, so angle d must be 100°.
Hope this helps! See attachment for visual.

There are six pizzas there are 36 players on the team. If each member has one slice and each pizza has eight slices how much pizza in fraction form will be left over.
There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.
To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.
Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.
Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.
To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.
Therefore, there will be 12 slices of pizza left over.
To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.
If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

una persona cobra 7/4 de una cantidad, gasta 1/4 y presta 1/8 ¿Que fraccion de la cantidad cobrada le quedo?
Answer: (11/8)
Step-by-step explanation:
I will answer this in English.
a person collects 7/4 of an amount, spends 1/4 and lends 1/8. What fraction of the amount collected is left?
If the amount is A, then he collects:
C = (7/4)*A
Now, he spends 1/4 and lends 1/8 of the amount A, so the fraction left is:
Left = (7/4)*A - (1/4)*A - (1/8)*A
now i will write 7/4 as 14/8 and 1/4 as 2/8.
left = (14/8)*A - (2/8)*A - (1/8)*A = ((14 - 2 - 1)/8)*A = (11/8)*A

The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.
Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.
We have:
z₁ = 7(cos(577°) + i sin(577°))
Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.
From the given information, we have:
z₂ = 21(cos(-7°) + i sin(-77°))
To find the quotient, we divide z₁ by z₂:
z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]
Substituting the given values, we have:
z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]
= (7/21) * [cos(584°) + i sin(584°)]
The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.
