Find the value of x, y, and z, in the rhombus below.
Answers
Answer:
x = 19, y = -7, z = -18
Step-by-step explanation:
Since its a rhombus and 1 side = 29, all sides = 29. Just solve each side.
2x - 9 = 29
2x = 38
x = 19
-3y + 8 = 29
-3y = 21
y = -7
-2z - 7 = 29
-2z = 36
z = -18
The value of the variables x, y, and z will be 19, -7, and -18, respectively.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
All the sides of the rhombus are congruent with each other.
Then the equations are given below.
2x - 9 = 29
-3y + 8 = 29
-2z - 7 = 29
Simplify the first equation, then we have
2x - 9 = 29
2x = 38
x = 19
Simplify the second equation, then we have
-3y + 8 = 29
3y = - 21
y = -7
Simplify the third equation, then we have
-2z - 7 = 29
2z = - 36
z = - 18
The value of the variables x, y, and z will be 19, -7, and -18, respectively.

Find the slope of the line that passes through (10, 8) and (1, 9).
Answers
Answer:
m = 1/9
Step-by-step explanation:
Given:
x = 10
y = 8
x1 = 1
y1 = 9
Solution:
y - y1 = m ( x - x1 )
9 - 8 = m ( 10 - 1 )
1 = 9m
m = 1/9

Angle AOC = 142°.
Find the value of y.
Answers
The value of y in the cyclic quadrilateral with ∠AOC(142°) is 38°
The diagram above represents a cyclic quadrilateral.
A cyclic quadrilateral has all it vertices on the circumference of the circle.
Therefore,
Opposite angles are supplementary. This means they add up to 180 degrees.
Therefore,
142° + y° = 180°
subtract 142 from both sides of the equation
142 - 142 + y = 180 - 142
y = 38°

If log x+y/5 = 1/2(log x + log y) the find the value of x/y + y/x ?
Answers
Given that
log (x+y)/5 =( 1/2) {log x+logy}
We know that
log a+ log b = log ab
⇛log (x+y)/5 =( 1/2) log(xy)
We know that log a^m = m log a
⇛log (x+y)/5 = log (xy)^1/2
⇛log (x+y)/5 = log√(xy)
⇛(x+y)/5 = √(xy)
On squaring both sides then
⇛{ (x+y)/5}^2 = {√(xy)}^2
⇛(x+y)^2/5^2 = xy
⇛(x^2+y^2+2xy)/25 = xy
⇛x^2+y^2+2xy = 25xy
⇛x^2+y^2 = 25xy-2xy
⇛x^2+y^2 = 23xy
⇛( x^2+y^2)/xy = 23
⇛(x^2/xy) +(y^2/xy) = 23
⇛{(x×x)/xy} +{(y×y)/xy} = 23
⇛(x/y)+(y/x) = 23
Therefore, (x/y)+(y/x) = 23
Hence, the value of (x/y)+(y/x) is 23.

Answers
Answer:

Step-by-step explanation:
The solution is 1.804 x 10⁷
The product of the two numbers is given by the equation A = 1.804 x 10⁷
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the product of two numbers be A
Now , the equation will be
Let the first number be P = 41
Let the second number be Q = 4.4 x 10⁵
The value of Q = 4.4 x 100000
The value of Q = 440000
The product of two numbers A = P x Q
Substituting the values in the equation , we get
The product of two numbers A = 41 x 440000
On simplifying the equation , we get
The product of two numbers A = 1,80,40,000
So , the value of A = 1.804 x 10⁷
Hence , the product of numbers is A = 1.804 x 10⁷

how many days would it take for a tiger to eat a boar
Answers
Answer: Tigers belong to the taxonomic order Carnivora, which mean that their diet is composed mainly of meat. Like all animals, they are heterotrophic organisms, so they must meet their nutritional requirements from other living beings.
They look for both medium and large prey in the wild to feed on them. The animals they consume change according to the area where they live, as different species will be available in each region. They have no problem taking down animals larger than themselves including water buffaloes and bears.
These cats are powerful and efficient predators with an anatomy designed for hunting. They have two large canine teeth and other sharp-edged teeth to cut the skin, flesh, and bones of prey. These functional dental pieces are the last upper premolar and the lower first molar.
Like any carnivore, its clavicles are reduced or absent, while the scaphoid, central and lunar bones of the wrist fuse with the lunar-scapular bone. As Tigers digest meat quickly, they have a simple stomach and a short intestine.
Tiger feeding.
Young Moose, a common prey of the Siberian tiger.
The Panthera tigris diet includes a large diversity of animals that are typically medium to large usually weighing more than 200 pounds, and even dare to attack other predators and animals of considerably larger size than theirs. Small animals make up a tiny part of their usual diet.
Tigers can stay up to two weeks without food, but when they catch prey, they can eat 75 pounds of meat at once.
