What else would need to be congruent to show that AABC=AXYZ by SAS?BGiven:ZBYAB=XYZO A. ZB=LYB. BC = YZC. AC = XZO D. C= _Z
Answers
We were given two triangles, ABC and XYZ. The problem also states that the angles B and Y are congruent, and the sides AB and XY are also congruent. We need to point out which information is missing so that we can prove the triangles are congruent by SAS.
The term SAS stands for Side-Angle-Side, it means that two triangles are similar when they have two congruent Sides and one congruent Angle. Since the problem already said that one side and one angle are congruent, then we only need one more side. From this, we can conclude that the correct option is B.

We are given the following equation in slope-intercept form.
[tex]y=-7x+1[/tex]The general form of slope-intercept form is given by
[tex]y=mx+b[/tex]So, we see that

So all those options that say to start on the x-axis are incorrect.
We start at 1 on the y-axis and plot that point.
Then from there, we go up (rise) 7 units and to the left (run) 1 unit.
Go up means positive and go left means negative so the slope becomes -7.

What is the approximate area they will have to paint to fill in this tree?
Answers
The area is 18. 8 ft².
From the question, we have
Area of a triangle = 1/2 base × height
= 1/2 × 5 × 3
= 1/2 × 15
= 7. 5 ft²
In trapezoid,
a = 4ft
b = 0. 2ft
h = 5ft
Area of trapezoid = 1/2*(a+b)*h
= 1/2*(4+0.2)*5
= 1/2*4.2*5 = 10. 5 ft²
Area of rectangle = length × width
= 0. 2 × 4
= 0. 8 ft²
Total area of tree = area of triangle + area of trapezoid + area of rectangle
= 7. 5 + 10. 5 + 0. 8
= 18. 8 ft²
Multiplication:
Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious. In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.

We have to calculate the perimeter of a pen that has an area expressed as
A = 3x²-7x+2.
We assume it is a rectangular pen, so it will have two different sides.
The area will be the product of this two side lengths, while the perimeter will be 2 times the sum of the lengths of the two sides.
Then, we start by rearranging the expression of A as a product of two factors.
We can do it by factorizing A.
To do that, we calculate the roots of A as:
[tex]\begin{gathered} x=\frac{-(-7)\pm\sqrt[]{(-7)^2-4\cdot3\cdot2}}{2\cdot3} \\ x=\frac{7\pm\sqrt[]{49-24}}{6} \\ x=\frac{7\pm\sqrt[]{25}}{6} \\ x=\frac{7\pm5}{6} \\ \Rightarrow x_1=\frac{7-5}{6}=\frac{2}{6}=\frac{1}{3} \\ \Rightarrow x_2=\frac{7+5}{6}=\frac{12}{6}=2 \end{gathered}[/tex]Then, we can now express A as:
[tex]\begin{gathered} A=3(x-\frac{1}{3})(x-2) \\ A=(3x-1)(x-2) \end{gathered}[/tex]Then, we can consider the pen to be a rectangle (or maybe square, depending on the value of x) with sides "3x-1" and "x-2".
Then, we can now calculate the perimeter as 2 times the sum of this sides:
[tex]\begin{gathered} P=2\lbrack(3x-1)+(x-2)\rbrack \\ P=2(3x-1+x-2) \\ P=2(4x-3) \\ P=8x-6 \end{gathered}[/tex]Answer: we can express the perimeter as 8x-6.
The longest runaway at an airport has the shape of rectangle and an area of 2,057,000 square feet. This runaway is 170 feet wide how long is the run away ? The length of the runaway is ?
Answers
The runway is 12100 ft long
Explanation:The area of a rectangle is given as:
A = wl
Where w is the width and l is the length
Given that A = 2, 057,000 sq. ft
w = 170 ft
Using these, we can easily find l
2,057,000 = 170l
l = 2,057,000/170
= 12100

The half-life is 6300 years.
From the question, we have
t_1/2 = 0.693/k
where,
t_1/2 = half-life
k = decay constant = 0.00011
substituting the value, we get
⇒t_1/2 = 0.693/0.00011
⇒t_1/2 = 6300 years
Half Life Period:
One of the main terms used in physics to describe the radioactive decay of a specific sample or element over a predetermined amount of time is half-life, also known as half-life period. When studying the subject, nuclear physics students will frequently run into the phrase. The term "exponential decay" is also frequently used to refer to both exponential and non-exponential decay, which are both common forms of decay processes. In fields other than physics, the word is used to describe the biological half-life of specific substances in the human body or in medications.

The maximum height is the vertex described by the parabola. The Vertex follows that formula:

Answers
Step 1: Problem
-x - 3y + 3z = 21
x + 4y + 5z = -1
5x + 7y - 2z = -34
Step 2: Concept
Apply substitute method to solve the three systems of equation.
Step 3: Method
Name the system of equations
-x - 3y + 3z = 21 ------------------------------ 1
x + 4y + 5z = -1 ------------------------------- 2
5x + 7y - 2z = -34 --------------------------3
From equation 1, make r subject of relation and substitute into 2 and 3
x = -3y + 3z - 21
Next, substitute x in equations 2 and 3.
In 2
- 3y + 3z - 21 + 4y + 5z = -1
y + 8z = -1 + 21
y + 8z = 20 ----------------------------------- (4)
In 3
5(-3y + 3z - 21) + 7y - 2z = -34
-15y + 15z - 105 + 7y - 2z = -34
-8y + 13z = - 34 + 105
-8y + 13z = 71 ------------------------------------- (5)
from 4, make y subject and substitute in 5
y = 20 - 8z
In 5
-8(20 - 8z) + 13z = 71
-160 + 64z + 13z = 71
77z = 71 + 160
77z = 231
z = 231/77
z = 3
y = 20 - 8(3)
y = 20 - 24
y = -4
x = -3y + 3z - 21
x = -3(-4) + 3(3) - 21
x = 12 + 9 - 21
x = 0
Step 4: Final answer
x = 0, y = -4 z = 3
