C3 in.
B 6 in.
DI in.
4. Find the area of quadrilateral PQRS.
F 34.1 units
G 65 units?
H 130 units?
J 360 units
Answer:
1: C =69.3 m2
2: F = ll units
3. C: 3 in.
4. G =65 units
Step-by-step explanation:
1: C =69.3 m2
We see from the figure that height of the parallelogram ABCD is not known and the base is 10 m
Taking the right angled triangle the height is given by
Sine theta= height/hypotenuse
height = hypotenuse* sine theta
= 8* sine 60
= 8* 0.866= 6.928
Area of parallelogram= base * height
= 10 * 6.928
= 69.28
=69.3 m²
2: F = ll units
We see from the figure that height of the parallelogram DEFG is not known and the base is 13 cm
Area of parallelogram= base * height
143 = 13 * height
Height = 143/13= 11 units
3. C: 3 in.
The area of the triangle = 1/2 * base * height
Let the height be x then the base is 3x
54= 1/2*x*3x
54= 3x²/2
27= 3x²
x²=27/3
x²= 9
x= 3
The height is 3 inches
4. G =65 units
Area of the quadrilateral = 1/2 *PR*QO + 1/2 *PR*OS
= 1/2*13*4+ 1/2*13*6
=26+ 39
= 65 units
These measurements are given in the diagram .

[tex]x^{2}[/tex]+8x+7
Answer:
(x + 1)(x + 7)
Step-by-step explanation:
Assuming you require the expression factored
x² + 8x + 7
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 1 and + 7 , since
1 × 7 = 7 and 1 + 7 = 8 , then
x² + 8x + 7 = (x + 1)(x + 7) ← in factored form

Two more than the quotient of a number and 5 is equal to 8
Answer:
30
Step-by-step explanation:
We can start by writing an equation:
2 + x / 5 = 8
We are adding 2 since we are asking for two more than the quotient, and it is set equal to 8 as given by the problem.
We can subtract 2 from both sides to isolate the x term:
2 + x / 5 = 8
-2 -2
x / 5 = 6
Now, we can multiply by 5 to cancel out the division by 5:
x / 5 = 6
* 5 * 5
x = 30
So, the number is 30.
The requried number is 30, and the equation model is x/5 + 2 = 8.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
In the question, we have given a statement, and using that we have to model an equation,
To model an equation 1 step is to assign a variable.
So let the number be x.
According to the quesiton,
Two is more than the quotient of a number and 5 is equal to 8
x/5 + 2 = 8
x/5 = 8 - 2
x /5 = 6
x = 5 × 6
x = 30
Thus, the requried number is 30, and the equation model is x/5 + 2 = 8.

The scale factor of two similar hexagons is 5:12. The smaller hexagon has an area of 24 square units. What is the area of the larger hexagon?
Answer: [tex]138.24\ \text{square units}[/tex]
Step-by-step explanation:
Given
The scale factor of two similar hexagons is 5:12.
The smaller hexagon has an area of 24 square units
we know, the ratio of two similar figures is equal to the square of the scale factor.
Suppose the area of the larger hexagon is A
[tex]\therefore \dfrac{24}{A}=\left[\dfrac{5}{12}\right]^2\\\\\Rightarrow A=\left[\dfrac{12}{5}\right]^2\times 24\\\\\Rightarrow A=138.24\ \text{square units}[/tex]

Answer:
X is about 58.41 degrees
Step-by-step explanation:
For this problem, lets use sine, since we have the opposite angle from x and we have the hypotenuse.
Therefore, with the equation for sine, we would get
sin(x) = 23/27
sin(x) = 0.851
Now, since we're solving for an angle, inverse it by adding a -1 to move over the sin.
x = sin-1 23/27
Last, use a calculator to get the answer.
X is about 58.41 degrees

In which interval is the median located?
40-49
30-39
20-29
10-19
Answer:
20 - 29
Step-by-step explanation:
Please find the complete question in the attached image
An histogram is a bar-like graph used to represent numerical data. On the y-axis is the frequency of the data and on the x-axis is the data
median is a measure of central tendency. It measures the middle number in a set of observation
there are 20 observations (visitors),
1, 2, 3,5,6, 7, 8, 9,| 10, 11, | 12,13,14,15,16,17,18,19,20
the median is 10 and 11 or 10.50
there are 9 numbers on either sides of 10 and 11
the 10th and 11th visitor would be found in the age group 20 - 29

Solve for v.
–9,45 − 6,1v = –2,8v + 13,98
Answer:
V would equal -7.1.
Step-by-step explanation:
It appears you have set the decimal points as commas. Let's remove that and replace it with decimal points. (AkA ".")
First, we move every term with "V" in this problem to the left.
-9.45 - 3.3v = 13.98
Next, we add -9.45 to 13.98 which equals 23.43.
We then make 3.3v negative.
-3.3v = 23.43
We then divide 23.43 and 3.3v by 3.3.
We cancel out 3.3v to leave 23.43/3.3.
We can now divide 23.43 by 3.3 to get -7.1.
V = -7.1
Answer:
V would equal -7.1.

Given y varies inversely as x, and y = 5 when x = 9. *Write the inverse function
Answer:
y = 45/x
Step-by-step explanation:
Here, we want to write an inverse relationship
for an inverse relationship, the product of both variables will be equal to the constant term
Let us have the constant term as k
Thus, we have it that;
xy = k
9 * 5 = k
k = 45
So the inverse function is;
xy = 45
or y = 45/x
if y is a function of x, we can have it as;
f(x) = 45/x

Answer:
Divide and then multiply the smaller ratio to get an equal ratio to the first one
Step-by-step explanation:
It helps a lot with algebra
Answer:
Dilate circle A by a scale factor of 3.
Step-by-step explanation:
In order to show if two triangles are similar you have to translate and dialate one of the triangles to compare it to the other one. So A and D are not it. The formula for C is incorrect so therefore the answer is B. Also i took the test :D
