Step-by-step explanation:
1. it is an equilateral triangle.
let base=2x
let h be the height from centre.
h/8=sin 30=1/2
h=1/2×8=4
so total height=8+4=12
again x/8=cos 60
x=(√3/2)×8=4√3
Base=2x=2×4√3=8√3
area of triangle=1/2×8√3×12=48√3 sq. units.
2.
one diagonal=3+8=11
second diagonal=5+5=10
area=1/2 d1d2=1/2×11×10=55 sq units

The equation 9 X 3 = 27 is used to find the area. Explain what
each factor stands for in the equation.
Answers
Answer:
In the equation 9 X 3 = 27, each factor stands for:
9 = length3 = width27 = areaStep-by-step explanation:
When you must know the area of a terrain or figure, you must know what is the form of that (circle, triangle, rectangle, square, or another figure), because, with this, you can use different formulas of the area, in the case given in the exercise, the formula used is to a rectangle (is the same that a square, but how the length and the width aren't equal, is a rectangle), knowing this the formula is:
Area of a rectangle = length * widthIn a rectangle, the length is bigger than the width, by this reason 9 is the length, 3 the width and the result is the area, how you can see below:
Area of a rectangle = 9 * 3 Area of a rectangle = 27Which of the following is the linear parent function?
A. Fx) = x
B. Fx) =1/x
C. F(x) = |x|
D. F(x) = x^3
Answers
Answer:
A linear parent function is the equation y = x or f(x) = x. A parent function is the simplest equation of a function. Thus, f(x) = x is the simplest of all linear functions and that is the reason why it is called linear parent function
Answer:
F(x) = x
Step-by-step explanation:
A line is of the form
x to the first power
1/x is not x to the first power and makes a curve
|x| makes a v shape

Brandon decided to take his family to a water park and celebrate the end of the school year. The cost is $9.50 for parking and $15 for each person for the entire day.
a. Define the variable and write a linear equation for the situation
b. Use the equation to find the cost if Brandon has 5 members in his family
Answers
Answer: a) Cost(x) = $9.50 + $15*x
b) $84.50
Step-by-step explanation:
a) If x is the number of members in the family, we can model this situation with a linear equation, where x is the variable.
We have:
A fixed $9.50 (this does not depend on the number of members in the family)
and $15 for each member, so the equation that represents this is:
Cost(x) = $9.50 + $15*x
b) now we have x = 5, then:
Cost(5) = $9.50 + $15*5 = $84.50
Answer:
a. y = 9.50 + 15a
b. total cost(y) = 84.5
Step-by-step explanation:
Brandon decided to take his family to a water park to celebrate the end of the school year.
The cost for parking is $ 9.50 which is a flat rate and compulsory rate for parked cars. The cost for each person is $15 .
a. The linear equation can be expressed below. The variable required in the linear equation will be the number of people that entered the water park(a) and the total cost (y)
let
a = number of person for the entire day
total cost = y
y = 9.50 + 15a
b. To find the cost for a whole family of 5 member can be calculated below.
Using the linear equation
total cost = 9.50 + 15a
total cost = 9.50 + 15(5)
total cost = 9.50 + 75
total cost(y)= 84.5

Find the measure of the largest angle in the diagram below. (Type the

Answers
Answer: 112
2x+3x+10=180
5x=170
x=34
3x+10=112
The measure of the largest angle in the diagram is 112 degrees.
What is Angle?An angle is formed when two straight lines or rays meet at a common endpoint.
The sum of two angles is 180 degrees when they are complementary.
2x+3x+10=180
Two times of x plus three times of x plus ten equal to one hundred eighty.
5x+10=180
Five times of x plus ten equal to one hundred eighty.
Subtract 10 from both the sides
5x=170
Divide both sides by 5
x=34
Now substitute x value in 3x+10 which is largest angle.
3(34)+10
102+10
112
Hence, the measure of the largest angle in the diagram is 112 degrees.

Answers
Answer:
C. (3,2)
Step-by-step explanation:
to begin the substitution method, we can begin by substituting the answer choice value into the given system or equations to determine if the values make the equation true.
the first choice is (2,1)
3(2) + 2(1) = 13
6 + 2 is not equal to 13. Therefore this answer choice is incorrect.
second choice (1,2)
3(1) + 2(2) = 13
3 + 4 is not equal to 13. This answer is also incorrect.
third choice (3,2)
3(3) + 2(2)
9 + 4 = 13 is true!
we can also substitute these x and y values for the equation underneath:
y = x - 1
2 = 3 - 1
2 = 2 is true! Therefore, C. (3,2) is correct!

C : 414.7
Step-by-step explanation:
I do not completely know if this is right or not, but I used reasoning to figure this out. I can easily find the area of a circle just based on the radius of it, and the radius of the circle (all parts included) is 452.39. And since the percentage of the shaded circle would have to be a lot larger to have the unshaded area only be 188, then I can reason that 414.7 would be the most reasonable answer.

If the number being divided does not end in 5 or 0, it being divided by 5 will not be equal. Therefor it might be better to try and use a calculator if you can't do it in your head.
Explanation:
First lets do the long division method. First we need to fit 5 into 5. That would be 1. So we write a 1 above the 546. Then we need to fit 5 into 4. Well it doesn't fit so we write a zero move another number. How many 5s fit into 46 well that would be 9. All we have left is a remainder of 1 which cannot fit into 5 and there are no more numbers

Function 2
y = −6x + 50
Which statement explains which function shows a greater rate of change?
Function 2 shows a greater rate of change because Jenny spends $6 each month and Sandra spends $5 each month.
Function 2 shows a greater rate of change because Jenny spends $50 each month and Sandra spends $15 each month.
Function 1 shows a greater rate of change because Sandra spends $15 each month and Jenny spends $44 each month.
Function 1 shows a greater rate of change because Sandra spends $5 each month and Jenny spends −$6 each month.
Answers
Answer:
A) Function 2 shows a greater rate of change because Jenny spends $6 each month and Sandra spends $5 each month.
Step-by-step explanation:
The y-intercept for Sandra is 55 and the slope is -5. While Jenny's y-intercept is 50 and slope is -6.
6 is a greater number therefore causing Jenny's slope to decrease faster causing her to have less money at a much faster rate. (rate of change=slope) Jeny's slope is decreasing at a faster rate of change because she is spending more money everyday than Sandra is.

You can determine the type of triangle using the following facts related to the converse of the pythag theorem
if a^2 + b^2 > c^2, then it is an obtuse triangle
if a^2+b^2<c^2, then it is an acute triangle
finally, if a^2+b^2=c^2, then it is a right triangle
