∠5 is a supplement of ∠6, and m∠5=78°. Find m∠6.
Answer:
[tex]102^\circ[/tex]
Step-by-step explanation:
Given that:
[tex]\angle 5[/tex] is a supplement of [tex]\angle 6[/tex].
m[tex]\angle 5[/tex] = 78°
To find:
m[tex]\angle 6[/tex] = ?
Solution:
First of all, let us learn about the concept of an angle being a supplement of the other angle.
[tex]\angle B[/tex] is known as supplement of [tex]\angle A[/tex], if sum of the two angles is equal to 180°.
[tex]i.e. \angle A +\angle B=180^\circ[/tex].
For example, angle made on one side by a line intersecting the other line are supplement of each other.
Here, we are given that [tex]\angle 5[/tex] is a supplement of [tex]\angle 6[/tex].
In other words:
[tex]\angle 5+\angle 6=180^\circ[/tex]
Putting value of [tex]\angle 5[/tex]:
[tex]\Rightarrow 78^\circ+\angle 6=180^\circ\\\Rightarrow \angle 6 =180^\circ-78^\circ\\\Rightarrow \bold{\angle 6 =102^\circ\\}[/tex]
So, the answer is: [tex]102^\circ[/tex]

PDF attached below All questions are related to each other
1. The first option is represented by a linear function, ∴ y = 50x + 150. The y intercept here is 150, as the first week is 200 dollars, not the 0th week. 200 - 50 = 150.
Given the domain here is 1 - 6 (6 weeks) we can plug in x as 1,2,3 etc and solve for y, completing the table.
Option A :
Week | 1 | 2 | 3 | 4 | 5 | 6 |
Amount Paid | 200 | 250 | 300 | 350 | 400 | 450 |
And for option b we have an exponential function. 1 + 10% = 1 + 0.1 = 1.1. Therefore we have the function ∴ y = 200( 1.1 )^x-1 that models this situation. Remember that we have " x - 1 " as the exponent rather than x, as the first week begins with 200 dollars, not the 0th week.
That gives us the following table,
Option B :
Week | 1 | 2 | 3 | 4 | 5 | 6 |
Amount Paid | 200 | 220 | 242 | 266.2 | 292.82 | 322.102 |
2. (a) We already calculated the " iterative rules " for each sequence in the first part. For your explanation on that behalf, just include the explanation above. Rule of Option A : y = 50x + 150. Rule of Option B : [tex]y = 200( 1.1 )^{x-1}[/tex].
(b) Let's take an example week and substitute into our equations to help clarify our friend's doubt. Say week 2...
y = 50(2) + 150 = 100 + 150 = 250 ✓
y = 200( 1.1 )^2-1 = 200( 1.1 )^1 = 200( 1.1 ) = 220 ✓
3. (a) A function is an equation that represents the relation between x and y, which is exactly the purpose of the rules y = 50x + 150, and y = 200( 1.1 )^x-1.
(b) I disagree with my friend. These particular examples do have y - intercepts, but just because a rule is a function, doesn't make it have a y - intercept. There are some exceptions, such as y = 1 / x.
(c) An input such as 18.5 is meaningless, as x represents the weeks. An employer doesn't provide the payments at half weeks.
4. Let's substitute 20 as x,
y = 50 * 20 + 150 = 1,000 + 150 = $1,150
y = 200( 1.1 )^x-1 = 200( 1.1 )^20-1 = 200( 1.1 )^19 = $1,223.1818
The first payment option will provide the greatest total income.

11 * 2 = 22
14 + 22 = 36
Answer: 36

x & y intercept for 4x+6y=12
Answer:
x- intercept at (3, 0)
y- intercept at (0, 2)
Step-by-step explanation:
x-intercept occurs at y=0.
4x +6y= 12
when y=0,
4x +6(0)= 12
4x= 12
x= 12 ÷4
x= 3
Thus, x-intercept occurs at x=3, at the point (3, 0).
y- intercept occurs at x=0.
4x +6y= 12
when x=0,
4(0) +6y= 12
6y= 12
y= 12 ÷6
y= 2
Thus, y- intercept occurs at the point (0, 2).

Step-by-step explanation:
The diagram is a straightedge and compass construction. C is the center of both circles.
Which of the following statements must be TRUE by construction?
Answer:
The correct option is;
AC and CD have the same length
Step-by-step explanation:
Given that the circle with center C, we have;
The length of AC extending from C to A being from the center to the circumference is the radial length of the smaller circle of center C.
Similarly, the length of the segment that extends from the center of the circle with center C to the circumference of the circle is the also the radial length of the smaller circle of center C.
Whereby the radial length of a circle is constant, then two radial lengths of the same circle are congruent and and circle radius AC is congruent to radius CD, which gives;
Length of AC = Length of CD or AC and CD have the same length.
The sum of a number and six is two less than half the same number.
Answer:
-16
Step-by-step explanation:
x+6=x/2-2
solve the equation, x=-16
check:
-16+6=-10
-16/2=-8
-10-(-8)=-2
If the sum of a number and six is two less than half the same number then the number is -16.
Given,
The sum of a number and six is two less than half the same number
We will find the unknown number.
We have,
The sum of a number and six is two less than half the same number.
Let the unknown number be M.
Let us separate the given statement into parts:
- Sum of a number and six
This can be written as M + 6.
- is means equal sign "=".
- Two less than half the same number.
This can be written as (1/2)M - 2.
Now,
We can write as:
M + 6 = (1/2)M - 2
M - (1/2)M = -2 - 6
(1/2)M = -8
M = -8 x 2
M = -16
Thus the unknown number is -16.
We can also crosscheck:
M + 6 = (1/2)M - 2
-16 + 6 = (1/2)(-16) - 2
-10 = -8 -2
-10 = -10
Hence proved.

Some friends want to see a movie that is showing at two different theaters in town. They plan to share three tubs of popcorn during the movie.
Movie theatre prices. Theatre A: ticket price 14 dollars 50 cents, popcorn 5 dollars 75 cents. Theatre B: ticket price 13 dollars, popcorn 6 dollars 75 cents.
Answer:
Let's call x as the number of friends, now, in Theatre A we have:
Price for x tickets = x*$14.50
price for 3 tubs of popcorn = 3*$5.75 = $17.25
Total price:
Pa(x) = $14.50*x + $17.25
Now, for Theatre B we have:
Price for x tickets = $13*x.
Price for 3 tubs of popcorn: = 3*$6.75 = $20.25
Total price:
Pb(x) = $13*x + $20.25.
Now, we can find the number of friends x in such case that they will pay the same in each theater by:
Pa(x) = Pb(x)
$14.50*x + $17.25 = $13*x + $20.25.
Now we solve this for x:
($14.50 - $13)*x = $20.25 - $17.25 = $3
$1.50*x = $3
x = $3/$1.50 = 2.
Then, if there are 2 friends, they will pay the same in both theatres
If there are more tha 2 friends, the cheaper place will be Theatre B, because the slope is smaller, which means that for each additional ticket the total price will increase less.

Answer:
The formula to find the voltage is:
[tex]v=\sqrt{P*R}[/tex]
And the voltage is 4 volts
Step-by-step explanation:
To get the equation of voltage you need to isolate v in one side of the equation. In order to do that, you need to remove the divisor/denominator and its square. How will you do that?
First, multiply both sides with R:
[tex]P*R=\frac{v^{2} }{R} *R[/tex]
That would result into removing the divisor R from the right side of the equation:
[tex]P*R=v^{2}[/tex]
Next, square-root both sides:
[tex]\sqrt{P*R} =\sqrt{v^{2} }[/tex]
That would result in removing the square of v from the right side of the equation:
[tex]\sqrt{P*R} =v[/tex]
Thus we get the equation, [tex]v=\sqrt{P*R}[/tex].
To find out the voltage, simply replace R with 32 and P with 0.5
[tex]v=\sqrt{0.5*32}[/tex]
[tex]r=\sqrt{16}[/tex]
[tex]r=4[/tex]
Thus, the voltage is 4 volts.

Answer:
Subtract 9 from each side of the equation.
m = – 11
Step-by-step explanation:
m + 9 = – 2
To solve the above equation, we simply subtract 9 from each side of the equation.
This is illustrated below:
m + 9 = – 2
Subtract 9 from each side of the equation
m + 9 – 9 = – 2 – 9
m + 0 = – 11

Answer:
Kindly check explanation
Step-by-step explanation:
Given the following instructions :
It can be deduced from part a that the final result will be twice the original number 'n'
The number 'n' multiplied by 4 = (4 * n) = 4n
10 added to 4n = 4n + 10
The result of the sum divide by 2 = (4n + 10) / 2
= 2n + 5
5 subtracted from the result of the quotient obtained : 2n +5 - 5 = 2n
Where n is the original number.

If you were to round 897.234 to the hundredths place, what would be the
number?
Your answer
This is a required question
Answer:
897.23
Step-by-step explanation:
The decimal places start at the tenths:
00.tenths, hundredths, thousandths
So you would need to end up with only two numbers after the decimal.
To round, if a number is 4 or less, leave the next number as it is.
Ex: 2.32 → 2.3 Rounding to the tenths
78.614 → 78.6 Rounding to the tenths
If the number is 5 or higher, round up one number
EX: 37.76 → 37.8 Rounding to the tenths
6.389 → 6.4 Rounding to the tenths
Our number, 897.234, needs to be rounded to the hundredths place, so use the number to its right to determine the rounded value. The number 4 means that the hundredths place will remain the same, so the new value is:
897.23
