1. The triangle depicted by the drawing has an actual area of 36 square units. What is the scale of the drawing? (Note: Each squ
are on the grid has a length of 1 unit.) What's the answer to this??
1 answer:
Answer:
the the scale of the drawing is 1/4
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
As we know that, the formula to find the are of a triangle is:
A = 1/2 b*h where:
- b is the base
- h is the height
From the photo, we can see that, the height is 3 units and the base is 6 units. So the area of the shaded triangle is:
A = 1/2 6*3 = 9 square units
Given that the triangle depicted by the drawing has an actual area of 36 square units. So the the scale of the drawing is:
area of the shaded triangle / the actual area
9 /36 = 1/4
Hope it will find you well.

Problem 4
Like the three earlier problems, we'll place the kicker at the origin and have her kick to the right. The two roots in this case are x = 0 and x = 20 to represent when the ball is on the ground.
This leads to the factors x and x-20 and the equation
We'll plug in (x,y) = (10,28) which is the vertex point. The 10 is the midpoint of 0 and 20 mentioned earlier.
Let's solve for 'a'.
This then leads us to:
The equation is in the form with

Problem 5
The same set up applies as before.
This time we have the roots x = 0 and x = 100 to lead to the factors x and x-100. We have the equation
We'll use the vertex point (50,12) to find 'a'.
Then we can find the standard form
