4 x 4=16
The perimeter of a square garden is 12 km. Find its area.
Answer:
The area of the garden is 9 km²
Step-by-step explanation:
If the garden is a square, that means that it's side length is one fourth of the total perimeter, giving us a length and width of 3km
That means that it's area is 3km × 3km, or 9km²
A ladder leans against the side of a house. The angle of elevation of the ladder is 73°, and the top of the ladder is 14 ft above the ground. Find the distance from the bottom of the ladder to the side of the house. Round your answer to the nearest tenth.
Answer:
4.3 feets
Step-by-step explanation:
Given that:
Angle of elevation = 73°
Horizontal distance from foot of ladder to bottom of wall = x feets
Height of ladder = 14 feets
The horizontal distance, x :
Using trigonometry :
Tan θ = opposite / Adjacent
Tan θ = 14 / x
Tan 73 = 14 / x
3.2708526 * x = 14
x = 14 / 3.2708526
x = 4.2802295
x = 4.3 feets
In an injection-molding operation, the length and width, denoted as X and Y, respectively, of each molded part are evaluated. Let A denote the event of 48 < X < 52 centimeters B denote the event of 9 < Y < 11 centimeters. Construct a Venn diagram that includes these events. Shade the areas that represent the following:
a. A
b. A ∩ B
c. A' ∪ B
d. A ∩ B
e. If these events were mutually exclusive, how successful would this production operation be? Would the process produce parts with X = 50 centimeters and Y = 10 centimeters?
Answer:
attached below
Step-by-step explanation:
Attached below are the Venn diagrams
A : 48 < X < 52 cm
B : 9 < Y < 11 cm
a) A
b) A ∩ B
c) A' ∪ B
d) A ∪ B
e) for events to be mutually exclusive it means that both events can not occur simultaneously i.e. A ∩ B = 0
the process would not be successful hence the process would not produce parts with X = 50 cm and Y = 10 cm

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to the nearest tenths place.
Answer:
Area of the composite figure = 175.1 square units
Step-by-step explanation:
Area of the composite figure given in the picture = Area of the parallelogram + Area of the semicircle formed on one side of the parallelogram
Area of the parallelogram = Base × Height
= 30 × 5
= 150 square units
Area of the semicircle = [tex]\frac{1}{2}(\pi r^{2})[/tex]
= [tex]\frac{1}{2}(\pi)(\frac{8}{2})^{2}[/tex]
= 8π
= 25.13
≈ 25.1 square units
Now area of the complete figure = 150 + 25.1
= 175.1 square units

If F(x) = 9x, which of the following is the inverse of Fx)?
Answer:
F⁻¹(x) = x/9
Step-by-step explanation:
To find the inverse of a function, you want to switch x and y in the equation and solve for y.
F(x) = 9x
x = 9F(x)
x/9 = F⁻¹(x)
Therefore, the inverse is F⁻¹(x) = x/9.

Answer:
y = -2x + 10
Step-by-step explanation:
y = mx + b is slope-intercept form where 'm' is the slope and 'b' is the y-intercept
use the point (2, 6), where 2 is the x-value and 6 is the y-value, and slope of -2 to find the y-intercept:
6 = (2)(-2) + b
6 = -4 + b
b = 10
y = -2x + 10

First
54 / 12 = 4.5
Then
Change it into a fraction
Write is fraction form 4.5 / 1
Multiply both numerator and denominator by 10 for every number after the decimal point
4.5 × 10
1 × 10
Which will equal 45/10
Then Reduce the fraction gives 9/2
Mr smith earns $75 a day plus $35 for each car he sells if e is the amount he earned and c is the number of cars he sold which expression below shows how much mr smith will earn in a day
Answer:
110
Step-by-step explanation:
So if add 75 + 35 you will get the number 110
Really hoped this helped
The expression Mr smith will earn in a day is e= 75 + 35c.
What is expression?
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an equation, a coefficient is a number that is multiplied by a variable.Given:
Mr smith earns $75 a day plus $35 for each.
if e is the amount he earned,
and c is the number of cars he sold
So, the amount he earned
e= 75 + 35c
Hence, the expression is e= 75 + 35c.

Step-by-step explanation:
The value of h is 8 units.
What are similar triangles?"Two triangles are similar when their corresponding sides are in proportion and all corresponding angles are equal."
For given question,
ΔBAD and ΔCBD are similar triangle.
So, their sides are in proportion.
[tex]\Rightarrow \frac{BA}{CB}= \frac{AD}{BD}= \frac{BD}{CD}[/tex] ..................(i)
For given figure,
BD = h, CD = 4 units
Now, we find the length of the side AD.
⇒ AD = AC - CD
⇒ AD = 20 - 4
⇒ AD = 16 units
From (i),
[tex]\Rightarrow \frac{AD}{BD}= \frac{BD}{CD} \\\\\Rightarrow \frac{16}{h} =\frac{h}{4}\\\\ \Rightarrow 16\times 4=h\times h\\\\\Rightarrow h^2=64\\\\\Rightarrow h=8[/tex]
Therefore, the value of h is 8 units.
