triangle ABC has perimeter 22cm
AB= 8cm
BC= 5cm
by calculation deduce whether triangle ABC is right-angled triangle
Answers

Answer:
not a right triangle
Step-by-step explanation:
The perimeter is 22, so we have ...
AB +BC +CA = 22
8 + 5 + CA = 22
CA = 22 -13 = 9
If this is a right triangle, the sum of the squares of the short sides will be equal to the square of the long side.
AB² +BC² = 8² +5² = 64 +25 = 89
This is not the same as ...
CA² = 9² = 81
The triangle is not a right triangle.

Additional comment
If you're familiar with a few Pythagorean triples, you know that a couple involving a side length 5 are (3, 4, 5) and (5, 12, 13). That is, (5, 8, 9) is NOT a Pythagorean triple, so you know immediately that those side lengths do not form a right triangle. (No calculation is necessary.)

8/11 x (5/9 - 1/6) ÷ 1 5/9
Answers
Answer:
28/165
Step-by-step explanation:
You always use the order of operations, and the order of operations says to solve parentheses first, so you would solve 5/9 - 1/6, and get 7/18.
You would do exponents next, if there were any, but there is not, so you move on to the next operation(s).
The next operations are multiplication and division. From left to right, multiplication is first, so you solve 8/11 x 7/18 and get 28/99. Then, there is a division problem to solve. The problem is 28/99 ÷ 15/9. If you solve that correctly, you will get the answer 28/165.
The next step would be to simplify 28/165, but it cannot be simplified, so you are left with the answer 28/165.

Step-by-step explanation:
Make two triangles (big and small triangle) and one rectangle. ( kinda like what's in the pic)
Area of big triangle:
b = 3 h = 3
1/2 x 3 x 3 = 4.5 sq units
Area of small triangle:
b = 2 h = 2
1/2 x 2 x 2 = 2 sq units
Area of rectangle:
l = 3 w = 2
3 x 2 = 6 sq units
Area of the figure: A. of rect. + A. of s. tri. + A. b. tri.
6 + 2 + 4.5 = 12.5 sq units
The function g(x) is a transformation of the cube root parent function, f(x) = 3/x . What function is g(x) help

Answers
The function g(x) is a transformation of the cube root parent function f(x) = ∛x will be g(x) = ∛(x - 4) - 3. Then the correct option is D.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function.
The function g(x) is a transformation of the cube root parent function that will be given below.
f(x) = ∛x.
If we subtract h in the variable of the function then the function shifts toward the left by h units.
And if we subtract k in the function then the function shifts downward by k units.
Then the function g(x) will be
g(x) = ∛(x - 4) - 3
Then the correct option is D.

A state offers two lottery games, Winone and PlayBall. Both games cost $2 per ticket.
• In Winone, the player picks a single letter from A to J and a single digit from 0 to 9. If both the letter and the digit match the letter and the
digit picked on that day, the player wins $150.
• In PlayBall, the player picks a single letter from A to T and a single digit from 0 to 9. If both the letter and the digit match the letter and the
digit picked on that day, the player wins $280.

Answers
Answer:
m∠NPM = 101
Step-by-step explanation:
Since LM is a straight line, Angle LPM and Angle NPM have to equal 180 degrees (they are supplementary), so we make the equation:
180-79=measure of angle NPM
m∠NPM = 101
Answer:
<NPM = 101°
Step-by-step explanation:
<NPM = 180° - <LPN ( because LPM is a straight line and it should measure 180°)
<NPM = 180° - 79°
<NPM = 101°

In a system of two linear equations, the lines represented by each equation have the same slope. Which could be the total number of solutions to the system of equation
Answers
Answer:
Please see explanation
Step-by-step explanation:
A system of linear equations in two variables represents two lines on graph.
When both the lines have same slope, there can be two cases
Same slope with different y-interceptsWhen two lines have same slope and different y-intercepts, that means that both lines are parallel and parallel lines have no solution.
Same slope with same y-interceptsWhen the slope of both lines is same and the y-intercept is also same, this means that both the equations refer to the same line. This means that the system has infinite number of solutions.
13. It takes Seymore, a slimy slug, 20 minutes to travel from his favorite bush to the local trash can (a distance of 30 meters), how far can he travel in 1 hour (60 minutes)?
Answers
Answer:
90 meters
Step-by-step explanation:
From the question we are to calculate the distance that the slug can move in 60 minutes.
From the question, we know that:
20 minutes = 30 meters
60 minutes = x meters
Cross Multiply
20 minutes × x meters = 30 meters × 60 minutes
x meters = 30 meters × 60 minutes/20 minutes
x meters = 90 meters
If the points are (-10, 3), (-2, 10) what is the slope?

Step-by-step explanation:
We can find the slope using the slope formula
