Find the perimeter and area of this trapezoid.
Answer:
area = 36 m^2
perimeter = 34m
Step-by-step explanation:
Area of a trapezoid is calculated by the following formula:
(a+b)/2 * h (a: base, b: base, h:height)
(6+12)/2 * 4 = 36 the area is 36 m^2
The perimeter is calculated by adding all side lengths or multiplying the sum of non-parallel sides by 2
Only the measure of AB=AC is missing to find it we can use the method in attached photo
and the perimeter is:
(12+5)*2 = 34

Answer:
4 quarters, 10 dimesStep-by-step explanation:
x + y = 14 --> x = 14 - y
$0.10x + $0.25y = $2.00, or 10x + 25y = 200
- we can plug this value for x from the first equation into the second:
10(14 - y) + 25y = 200
140 - 10y + 25y = 200
140 + 15y = 200
15y = 60
y = 4 --> 4 quarters ($0.25 x 4 = $1.00)
if y = 4, then x = 14 - y --> x = 10 --> 10 dimes (0.10 x 10 = $1.00)
matches the second equation where these add up to $2.00
Answer:
1 way is 10 dimes and 4 quartes
I can only come up with one way

Answer:
a = 12
b = 6
Step-by-step explanation:
You have a 30°-60°-90° triangle which is a special right triangle. We memorize the ratios of the sides and can find the sides given just one side, by using the relationships between the sides, so we don't have to use trig ratios.
Generally, the LONGEST side (hypotenuse) is twice the shortest side. Or, the SHORTEST side is half the longest side (hypotenuse). The LONGER LEG is the short leg × sqrt(3).
Or the SHORT LEG is the
longer leg/sqroot(3)
You are given the long leg here. You have:
Long leg = 6sqroot(3)
So the short leg must be 6.
bc, longer leg IS Short leg×sqroot(3)
short leg =6
Then the LONGEST side (hypotenuse) has to be twice that.
LONGEST side = 12
Where it says "Prove side c" maybe that is like doing a check.
6^2 + (6sqrt3)^2 = 12^2
36 + 108 = 144
144=144

Sam claims that when he completes the transformation f(x) +3, the
parent function would move three units to the left.
Part A: Do you agree or disagree? Why or why not?
Part B: What misconception do you think Sam needs to clear up?
A) Disagree, The transformation f(x) + 3 represents moving the graph vertically up by 3 units.
B) A vertical transformation involves changing the y-coordinate of the graph, while a horizontal transformation involves changing the x-coordinate of the graph.
What is Translation?A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Since, We know that;
The transformation f(x) + 3 represents moving the graph vertically up by 3 units.
Therefore, the parent function would not move three units to the left.
It seems that Sam has a misconception about vertical and horizontal transformations.
For clarify, a vertical transformation involves changing the y-coordinate of the graph, while a horizontal transformation involves changing the x-coordinate of the graph.
Thus, We get;
A) Disagree, The transformation f(x) + 3 represents moving the graph vertically up by 3 units.
B) A vertical transformation involves changing the y-coordinate of the graph, while a horizontal transformation involves changing the x-coordinate of the graph.

Options
205 metres
875 metres

215 metres
The distance from tree 1 to tree 3 is about 205 meters.
EquationAn equation is an expression used to show the relationship between two or more variables and numbers.
Let a represent the distance from tree 1 to 2, b from 2 to 3 and c from tree 3 to 1.
Hence:
a + b = 335
Also:
b + c + a = 540
a + b + c = 540
335 + c = 540
c = 205 meters
The distance from tree 1 to tree 3 is about 205 meters.

Answer the questions in the pictures..
Answer:
1.d
2.b
3.c
4.d
5.c
Step-by-step explanation:
1. f(x) + g(x) = x - 11.
2. f(x) - g(x) = - 3x + 9.
3. f.g = 30x² + 28x - 6, all real numbers.
4. f/g = x + 4, all real numbers, x ≠ 4.
5. It doesn't matter which discount is applied first the result is the same.
What is a composite function?When the output of one function is given to the input of another function they are called composite functions.In (fog)x which is [f{g(x)}] here the out of the function g(x) is the input of the function f(x).
1. f(x) = - 5x - 4 and g(x) = 6x - 7.
Therefore, f(x) + g(x) = - 5x - 4 + 6x - 7.
f(x) + g(x) = x - 11.
2. f(x) = 3x + 2 and g(x) = 6x - 7.
Therefore, f(x) - g(x) = 3x + 2 - (6x - 7).
f(x) - g(x) = 3x + 2 - 6x + 7.
f(x) - g(x) = - 3x + 9.
3. f(x) = 5x + 3 and g(x) = 6x - 2.
Therefore, f.g = f(x)×g(x) = f(x).g(x).
f.g = (-5x + 3)(6x - 2).
f.g = -30x² + 10x + 18x - 6.
f.g = 30x² + 28x - 6.
The domain is all real numbers no restrictions.
4. f(x) = x² - 16 and g(x) = x + 4.
Therefore, f/g = f(x)/g(x).
f/g = (x² - 16)/(x + 4)(x - 4).
f/g = (x + 4)(x - 4)/(x - 4).
f/g = x + 4.
The domain of f/g is all real numbers except x ≠ 4.
5. Let, The original amount be 100.
25% off on 100 is 75 and 10% off again is 75 - 7.5 = 67.5.
Again, 10% off on 100 is 90 and 25% off on 90 is 90×0.75 = 67.5.
So, Both way is the same.

What is area of shaded
Answer:225
Step-by-step explanation:
we start by finding the area of the unshaded triangles and subtracting them from the total area of the box.
The total length of the top is 20 and the total length of the bottom side is 18
20-18=2 so the small unshaded part on the bottom side is 2. with this we can find the left triangle. triangle area is base times height over 2 so the area of the unshaded triangle on the left is 15*2/2=15.
We know the small unshaded bit on the right side is 6 as it is shown on the diagram. again, we can use base times height over 2 to get the area of the top unshaded triangle. 6*20/2= 60.
We can do base times height to find the total area of the rectangle
15*20=300
300-15-60=225
