A triangle has a base 5 cm and a height of 8 cm what is the area of the triangle


Answer 1


20 cm

Step-by-step explanation:

Area of a triangle is base x height/2, so in this case its 5x8/2 which is 40/2 therefor making the answer 20

2. Customers who purchase a certain model of car can order an engine in any of three sizes. Of all cars of this type sold, 45% have a small engine, 35% have a medium-sized engine, and 20% have a large engine. Of cars with the small engine, 10% fail an emission test within two years of purchase, while 12% of those with the medium size and 15% of those with the large engine fail. If a randomly chosen car of this model fails an emission test within two years, what is the probability it is a car with a small engine

:( Our professor has not shared the lecture notes yet (he doesn't let us write in class unless we're working out a problem, Dumb thing to do I know) and I have such a horrible memory with math especially with dealing with fractions. I can't remember how we did the similar problem today. Please explain step by step with this equation i'm going to provide. :) Thank you kind Stranger(s) for taking the time to answer it.If x−y=2 and x=5/2, find y.

Can someone explain how to do it aswell please and thank you



B: 24ft^2

Step-by-step explanation:

Area of triangle = (base x height)/2

Step 1: form an equation

a = (12ft x 4ft)/2

Step 2: solve equation

a = 48ft^2 / 2

a = 24ft^2

*the base is the measurement for the bottom of a triangle while height is the measurement of the length from the bottom to the top of a triangle*

Write the equation in standard form using integers y=3x+8

Final answer:

Multiplying a number by 3 usually does not yield the same result as adding 6 to it, except in the case of the number 3. For all other numbers, the results are different.


In mathematics, when we multiply a number by 3 it does not usually yield the same value as when we add 6 to the number. However, there is one instance in which this statement is incorrect. Let's consider the number 3. If we multiply 3 by 3 we get 9, and if we add 6 to 3 we also get 9. In all other instances, multiplying a number by 3 will not yield the same result as adding 6 to that number. For example, if we take the number 4, multiplying it by 3 gives us 12, but adding 6 to it gives us 10, which are different.

The correct answer is C

Step-by-step explanation:

X+U= [-1,  -1] on the top and [0, -23/4] on the bottom

Therefore A-(X+U) gives you [5/3, 7] on the top and [4, 5] on the bottom

What is the best approximation for the perimeter of polygon ABCDE?



- The coordinates of the points read from the graph given are:






- To find the perimeter, we can use the distance between two points formula to find the lengths of each side of the polygon after which we add them up.

- Thus, we have:

\begin{gathered} D=√((y_2-y_1)^2+(x_2-x_1)^2)\text{ \lparen Distance between two points\rparen} \n \n AB=√((6-3)^2+(0--2)^2) \n AB=√(9+4)=√(13) \n \n BC=√((6-4)^2+(0-5)^2) \n BC=√(4+25)=√(29) \n \n CD=√((4--1)^2+(5-3)^2) \n CD=√(25+4)=√(29) \n \n DE=√((-2--1)^2+(-1-3)^2) \n DE=√(1+16)=√(17) \n \n AE=√((3--2)^2+(-2--1)^2) \n AE=√(25+1)=√(26) \end{gathered}

- Thus, the Perimeter is

\begin{gathered} P=AB+BC+CD+DE+AE \n P=√(13)+√(29)+√(29)+√(17)+√(26) \n P=23.598006...\approx24units \end{gathered}

- Thus the best approximation is 24.3 units (OPTION B)

F(x)=3x-7 and g(x)=(1/3)x+7 are inverses of each other.





Step-by-step explanation:

Sorry for the lat reply hopefully you still have that question ready. But basically in order for these equations to be considered inverses of one another it has to map its domain value and switch it to the range value and in this case it does not match the inverse when graphed.

Final answer:

The functions f(x) = 3x - 7 and g(x) = (1/3)x + 7 are inverses of each other.


Two functions are inverses of each other if the composition of the functions results in the identity function. To check if f(x) = 3x - 7 and g(x) = (1/3)x + 7 are inverses, we need to find their composition.

Let's substitute g(x) into f(x) and simplify: f(g(x)) = f((1/3)x + 7) = 3((1/3)x + 7) - 7 = x + 7 - 7 = x.

Since f(g(x)) = x, it means that f(x) and g(x) are inverses of each other, and therefore the statement is True.
