The other side of the rectangle is 9 cm.
Given that:-
Perimeter of the rectangle = 28 cm
One side of the rectangle = 5 cm
We have to find the other side of the rectangle.
Let the length of the rectangle be 5 cm and,
The breadth of the rectangle be b cm.
We know that,
Perimeter of the rectangle = 2(l + b)
Hence, we can write,
2(5 + b) = 28
5 + b = 28/2
5 + b = 14
b = 14 - 5
b = 9 cm
Hence, the other side of the rectangle is 9 cm.

Two angles are supplementary.
The measure of the larger angle is four more than three times the measure of the smaller angle. Find the measures of both angles.
Answer:
44° and 136°
Step-by-step explanation:
let x represent the smaller angle then larger angle is 3x + 4
supplementary angles sum to 180° , so
x + 3x + 4 = 180
4x + 4 = 180 ( subtract 4 from both sides )
4x = 176 ( divide both sides by 4 )
x = 44
3x + 4 = 3(44) + 4 = 132 + 4 = 136
then
smaller angle = 44° and larger angle = 136°

Tonio works for a website that sells theater tickets and receives a base salary of $18,200 per year. He earns a commission of 2.3% for all ticket sales, which average $15,500 per week. He also gets a "viewed” fee of 3 cents each time someone comes to the website, whether or not any tickets are purchased. The number of visitors to the website averages 12,400 per month a) what is the total commission Tonio will earn this year. b) What is the total amount Tonio earns from visits to the website?c) What are Tonio’s total earnings for the year?
Tonio's salary is composed by:
- A base value of $18,200.
- A commission of 2.3% for all ticket sales, which average $15,500 per week. Hence 52 x 15,500 per year, as a year has 52 weeks.
- Another commission of $0.03 per visitor to the website, which averages 12,400 per month, hence 12 x 12,400 per year, as a year has 12 months.
Then, the total commissions are given by:
T = 0.023x52x15500 + 0.03x12x12400 = 23002
Tonio will earn a total of $23,002 in commissions this year.
Total amount Tonio earns from visits to the website: 0.03x12x12400 = $4464
Tonio’s total earnings: $18,200 + $23,002 = $41202

The correct option is
This relation is a function because each input has exactly one output.
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
From the figure the input are distinct and no input get coincide with output.
So, A function is a relation that states that there should only be one output for each input.
Alternatively, we could say that a function is a special sort of relation (a collection of ordered pairs) that adheres to the rule that every X-value should only be connected with one y-value.
Hence, This relation is a function because each input has exactly one output.

The measure of side AC from the triangle ABC is 57 units.
Given that, ∠BTC=(3x+3)°, CT=x+8 and TA=x-9.
What is the altitude length?The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex.
Here, BT is an altitude
The altitude of a triangle is the perpendicular to the opposite side of triangle.
Now,
(3x+3)°=90°
⇒ 3x=87
⇒ x=29
So, CT=x+8
= 29+8=37
TA=x-9
=29-9=20
So, AC=CT+TA
= 37+20
= 57 units
Therefore, the measure of side AC from the triangle ABC is 57 units.

measures the distance from the stake to the pole to be 5 ft. She then measures the
distance from the pole to the tower to be 21 ft. Find the length of the guy wire, to the
nearest foot.
Answer:
68 ft
Step-by-step explanation:
You want the length of a guy wire from a stake to the top of a cell tower if the stake is 5 ft from a 12-ft pole that is 21 ft from the tower. The guy wire crosses the top of the pole.
TrianglesThe attached diagram shows the geometry. The smaller triangle is a right triangle with legs 5 and 12. Its hypotenuse is ...
c = √(5² +12²) = √169 = 13
The larger triangle is similar and has a base of 21+5 = 26 units. This means its hypotenuse, the length of the wire, will be 26/5 times the length of the hypotenuse of the smaller triangle.
guy wire length = (26/5)(13 ft) = 67.6 ft ≈ 68 ft
The length of the guy wire is about 68 feet.

Find the parallel line for (2,0) y=-5x+3
The linear equation parallel to y=-5x+3 is:
y = -5*x + 10
How to find the parallel line?Two lines are parallel if and only if both lines have the same slope.
Remember that the general line is:
y = m*x + b
Where m is the slope and b is the y-intercept.
So a line parallel to:
y = -5x + 3
Must have a slope equal to -5, so our line is:
y = -5*x + b
To find the value of b we use the fact that the line passes through (2, 0), then:
0 = -5*2 + b
0 = -10 + b
10 = b
Then the line is:
