For a triangle with length of its sides of 5, 13, and 14, determine if it is a right triangle.
Answer:
it's not a right triangle
Step-by-step explanation:
5² + 13² = 14²
=> 25 + 169 = 196
=> 194 ≠ 196
The length of the triangles is 5 units , 13 units and 14 units and it is not a right angled triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measures of the sides of the triangle are 5 units , 13 units and 14 units
And , To determine if the triangle with sides 5, 13, and 14 is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.
If the theorem holds true for the given triangle, then it is a right triangle.
Let's check:
5² + 13² = 25 + 169 = 194
14² ≠ 194
Since 5² + 13² is not equal to 14², the triangle with sides 5, 13, and 14 is not a right triangle.
Hence , the triangle is not a right triangle

Each soda costs $4.50 at the baseball game. Which of the following represents the dependent variable?
Answer:
The price of the soda.
Step-by-step explanation:
The dependent variable is the variable defined to be dependent on another object, typically the independent variable. That means the variable that varies based off of another value is the dependent variable. In this situation, as the number of sodas bought increases, the total price increases. The price varies off of the number of sodas because the increase in sodas causes it to increase. Thus, the price is the dependent variable.
The dependent variable would be the total cost of the sodas.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Each soda costs $4.50 at the baseball game.
Here, The cost of the sodas is dependent on the number of sodas purchased, which is the independent variable.
Thus, The dependent variable would be the total cost of the sodas.

An exponential function has the equation y = (0.5)^x-1. Four points from a different function as shown in the table. For what values of x will two functions be equal?
Answer: f(x) = 64 * (3/4)^x
Step-by-step explanation: f(x)=ab^x
When x=0 f(x) = 64
64 = ab^0
b^0 =1 so
64 =a
f(x)=64 b^x
When x=1 f(x) = 48
48 = 64 *b
Divide by 64
48/64 =b
6/8 =b
3/4 =b
f(x) = 64 * (3/4)^x

Answer:
1.) 88cm²
2.) 44.5cm²
3.) 141.37cm²
4.) 44cm²
Step-by-step explanation:
Alrighty, we're just going to do an abridged version, but if you need me to explain it more, I can:
1.) 6 x 8 ÷ 2 = 24
8 x 8 = 64
64 + 24 = 88
1.) 88cm²
2.) 2 + 2 + 3 = 7
7 x 5 ÷ 2 = 17.5
9 x 3 = 27
27 + 17.5 = 44.5
2.) 44.5cm²
3.) 3.14 x 3² = 28.27
3.14 x 6² = 113.1
28.27 + 113.1 = 141.37
3.) 141.37cm²
4.) 3.14 x 4² ÷ 2 = 25.135
4 x 2 = 8
8 x 9 ÷ 2 = 36
8 + 36 = 44

The circumference of a circular garden is 128.74 feet. What is the diameter of the garden? Use 3.14 and do not round your answer.
Answer:
41 feet
Step-by-step explanation:
For a radius r, the circumference is [tex]2\pi r[/tex] and the diameter is [tex]2r[/tex], so to get diameter, we can just divide the circumference by pi and we get the answer. Using 3.14 for pi we get:
[tex]127.74 / 3.14 = 41[/tex]

What is the surface area of the triangular prism shown?
Answer:
Step-by-step explanation:
we need to find the surface area of the shapes before adding them together. the triangles are 6*4 and since there are two, we do not need to divide by 2. (normally to find the area of a triangle it is base times height divided by 2)
so the area of the triangles are 24 units. Next we have the outer rectangles. 7*5=35. Since there are 2, we multiply by 2. Last we have the middle rectangle. 7*6=42.
the whole equation would be: 24+70+42= 136
so your answer would be B: 136.

Help, please! I'm confused and don't know what to do..
Answer:
B. 30
Step-by-step explanation:
What we know: Beyunka has 6 baseballs that she keeps. That is 1/5 of the total that comes in one case.
What we need to know: How many baseballs are in one case?
What we need to do: Divide 6 by 1/5 (or multiply by 5).
6 / (1/5)
Dividing a fraction is the same thing as multiplying by its inverse.
6 * 5
Multiply 6 by 5 to get 30.
30
There are 30 baseballs in one case, so B is our answer.

Solve 4/9 plus x =7/9 x =
Answer:
x = 1/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x + 4/9 = 7/9
Step 2: Subtract 4/9 from both sides.
x + 4/9 - 4/9 = 7/9 - 4/9
x = 1/3
Answer:
x = 1/3 (or) 3/9
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ (4/9) + x = 7/9
Then the value of x will be,
→ (4/9) + x = 7/9
→ x = (7/9) - (4/9)
→ x = (7 - 4)/9
→ x = 3/9
→ [ x = 1/3 ]
Hence, the value of x is 1/3.

Jada, Diego, and Elena each use the same spinner that has four (not necessarily equal sized) sections marked A, B, C, and D.
Answer:
Diego is the most accurate, the probability of landing on B is 25% and he guessed 20% which is the closest to 25%
None of them match exactly because since they are not all equally sized, there is no way of telling exactly what the probability of landing on the sections are.
