Draw a quadrilateral ABCD with AB = 8.5cm, BC =4.5cm, CD =5cm , DA = 6cm , BD =7.5cm. Draw an equal area Triangle
Answers
Answer:
Check below please
Step-by-step explanation:
A quadrilateral is a polygon with four sides.
Then let's plot it, check it below.
1) Since 5 line segments were given for a quadrilateral, one of them is an interior one. In this quadrilateral, a rhombus. We have a diagonal, id est a line segment between non-consecutive points.
2) Let's calculate the area of this rhombus. Since this polygon is made up of two triangles let's find it using Heron's Formula, not very popular. But equally valid, also we don't have the height nor angles.
All we need is the semi-perimeter, (half of the Perimeter (2P) and plug it in the formula:
[tex]\bigtriangleup ABD semi-perimeter:\frac{6+8.5+7.5}{2} \therefore s=11\\Area \:\bigtriangleup ABD=\sqrt{11(11-6)(11-8.5)(11-7.5)}=\frac{5\sqrt{77}}{2} \approx21.94 cm\\\\\bigtriangleup \:BCD\: semi-perimeter:\frac{4.5+5+7.5}{2} \therefore s=8.5\\\\Area \bigtriangleup BCD=\sqrt{8.5(8.5-4.5)(8.5-5)(8.5-7.5)}=\sqrt{119}\approx 10.90[/tex]
[tex]Area\: of\: Rhombus\: ABCD=21.94+10.90=32.84 cm^2[/tex]
3) Well, now we need to trace a triangle whose area is 32.84 cm^2. From the classical formula for Area of Triangles we can write:
[tex]\frac{b*h}{2}=32.84 \therefore b*h=65.68[/tex]
Let's find out two values one for the base and another for height. Since 65.58 can be divided both by two and three, it is divisible by 6.
So
[tex]65.58 : 6 =10.93\\b=6\\h=10.93[/tex]

The slope of the line whose equation is 5x - 3y = 4 is
Answers
Answer:
The slope is 5/3
Step-by-step explanation:
5x - 3y = 4
Solve for y
Subtract 5x from each side
5x-5x - 3y =-5x+ 4
-3y = -5x+4
Divide each side by -3
-3y/-3 = -5x/-3 +4/-3
y = 5/3x -4/3
This is in the form
y =mx+b
The slope is m and the y intercept is b
The slope is 5/3

I will mark you brainliest!!!! Which statement is true for f(x)=6•(7)x?
Answers
Answer:
D
Step-by-step explanation:
A. The domain of this function is infinite, since x can be any number.
B. To find the y intercept, you need to set x to 0. 7^x will become 1, and 6*1=6, so the y intercept is (0,6).
C. This function is not always decreasing. For instance, when x is positive, it exponenentially increases.
D. As I said before, the y intercept of the function is (0,6), meaning that this statement is correct.

2b) A farmer is building a pen inside a barn. The pen will be in the shape of a right triangle.
The farmer has 14 feet of barn wall to use for one side of the pen and wants another side of the pen to be 15 feet long.
a. To the nearest tenth of a foot, find all possible lengths for the third side of the triangle.
b. The farmer wants the area of the pen to be as large as possible. What length should he choose for the third side? Justify your answer.
Answers
Answer:
For the pen to be as large as possible, the length the farmer should choose for the third side should be 20.52 feet
Step-by-step explanation:
The length of one side of the right triangle = 14 feet
The length of the other side = 15 feet
Therefore, the length of the third side can be one of the following side lengths;
[tex]S_{3,1} = \sqrt{14^2 + 15^2} = \sqrt{421} = 20.52 \ feet[/tex]
[tex]S_{3,2} = \sqrt{15^2 - 14^2} = \sqrt{29} = 5.39 \ feet[/tex]
The possible lengths of the third side of the triangle are;
Third side = 20.52 feet and
Third side = 5.39 feet
b. For the area of the pen to be as large as possible, we have;
With third side = 20.52 feet, area of the pen = 0.5 × 15 × 14 = 105 ft²
With third side = 5.39 feet, area of the pen = 0.5 × 5.39 × 14 = 37.7 ft²
Therefore, for the pen to be as large as possible, the farmer should choose 20.52 feet as he third side.
Answer:
a. c ≈ 20.5 ft (first possibility)
b ≈ 5.4 ft(other possibility)
b. The farmer should choose the side that has 20.5 ft for the third side because it provide more larger area as needed by the farmer.
Step-by-step explanation:
The pen the farmer wants to build is a right angle triangle. one side of the triangle is 14 ft while another side is 15 ft.
A right angle triangle has opposite side, adjacent side and an hypotenuse which is the longest side.
a. To the nearest tenth of a foot, find all possible lengths for the third side of the triangle.
Pythagoras theorem can be used to solve any sides of the triangle when given 2 sides.
We are not told which side is the hypotenuse or the adjacent or the opposites side. Therefore , the possible length for the third side can be computed using Pythagoras theorem.
c² = a² + b²
c = hypotenuse
while a and b can be any of opposite or adjacent sides. The first possible length can be when both sides are the legs of the triangle (no hypotenuse)
c² = 14² + 15²
c² = 196 + 225
c² = 421
c= √421
c = 20.5182845287
c ≈ 20.5 ft (first possibility)
The other possibility of the third side is when the hypotenuse is Known and one other side(either adjacent or opposite). We can use only 15 since it should be the longest side.
c² = a² + b²
c² - a² = b²
15² - 14² = b²
225 - 196 = b²
b² = 29
b = √29
b = 5.38516480713
b ≈ 5.4 ft(other possibility)
b. The farmer wants the area of the pen to be as large as possible. What length should he choose for the third side? Justify your answer.
The two scenarios are as follows
First area
area = 1/2 × base × height
area = 1/2 × 14 × 15 = 210/2 = 105 ft²
Second area
area = 1/2 × base × height
area = 1/2 × 5.4 × 14 = 75.6/2 = 37.8 ft²
The farmer should choose the side that has 20.5 ft for the third side because it provide more larger area as needed by the farmer.

Answers
Answer: x² - x - 12
Step-by-step explanation: When multiplying two binomials together, we can use the F.O.I.L. method.
First, Outer, Inner, Last.
We take the product of the first terms which is x² plus the product of the outer terms which is -4x plus the product of the inner terms which is 3x plus the product of the last terms which is -12.
So we have x² - 4x + 3x - 12.
Simplifying from here by combing the middle terms, we have x² - x - 12.
Pay very close attention to your positives and negatives as you F.O.I.L. because this is the area where most mistakes occur.

Here, we are told that 6kg of apple was used to make 90 more sandwiches and we need to know the number of sandwiches that can be made from 12kg of apples.
Now;
6kg made 90 sandwiches
12kg will make x sandwiches
To get x, we simply cross multiply
6 * x = 12 * 90
x = (12 * 90)/6
x = 2 * 90
x = 180 sandwiches

Describe fully the single transformation that maps triangle a onto triangle b
Answers
Answer:
reflection of Δa about y=2 results in Δb
Step-by-step explanation:
The single transformation that maps triangle a onto triangle b is: Reflection about y=2
Triangle A should be reflected about y=2 to map it onto Triangle B.
Here, from the given figure we get,
Coordinates of the vertices of triangle (A) are A(1, 3), B(2, 3) and C(1, 5)
After transformation of triangle A, coordinates of the vertices A', B' and C' of the image triangle (B) are,
A'(1, 1), B'(2, 1) and C'(1, -1)
Lets choose point A to find the rule of transformation,
A(1, 3) → A'(1, 1)
Rule → (x, y) → (x, 2 - (y - 2)) or (x, y) → (x, 4 - y)
It shows triangle (A) has been reflected across a line y = 2.
Therefore, Triangle A should be reflected about y=2 to map it onto Triangle B.

While Diane was visiting her sister in Kingwood, she bought a bunch of balloons that was marked down 20% from an original price of $5. If the sales tax in Kingwood is 8.5%, what was the total cost of the bunch of balloons? $
Answers
Answer:
$4.34
Step-by-step explanation:
Given the information:
The original price: $5Discount : 20% Tax: 8.5%We can find out the actual price that Diane bought a bunch of balloons that was marked down 20% is:
= the original price (100% - discount rate)
= 5(100% -20%)
= $4
The tax amount she need to pay is:= The actual price*tax rate
= $4*8.5%
= $0.34
=> the total cost of the bunch of balloons :
The actual price + tax price
= $4 + $0.34
= $4.34

Step-by-step explanation:
Given the function g(x) shown on the graph
One of the points of the parabola is (-3.5, 0).
The point x=-3.5 is one of the solution of the parabola since it intersects the x-axis at that point.
The other point of intersection is on the positive side between 0 and 1.
Therefore, g(x) has two solutions: One negative real number and one positive real number.
Therefore, g(x) has all real solutions.

This means that for every cinnamon muffin, 4 blueberry muffins were sold.
In other words, the ratio of cinnamon muffins to blueberry was 1/4.
60 blueberry muffins were sold on Monday.
This means that the number of cranberry muffins sold was:
