Answer:
Grasses: 12
Weeds: 29
Trees: 39
Step-by-step explanation:
Let G, W and T represent number of grasses, weeds, and trees that are major pollen sources.
We have been given that there are 80 major sources of pollen in state A. We can represent this information in an equation as:
We are told that the number of weeds is 7 less than thrice the number of grasses. We can represent this information in an equation as:
We are also told that the number of trees is 3 more than thrice the number of grasses. We can represent this information in an equation as:
Upon substituting equation (2) and equation (3) in equation (1), we will get:
Therefore, there are 12 grasses that are major pollen sources.
Number of weeds that are major pollen sources:
Therefore, there are 29 weeds that are major pollen sources.
Number of trees that are major pollen sources:
Therefore, there are 39 trees that are major pollen sources.
Answer:
Hi there I was just working on this question on UsaTestPrep and idk if the answer is really correct but here: C: reflection then rotation.
Step-by-step explanation:
Extra Info:
Dilation is when the shape changes in size, which doesn't happen.
Translation is when it just moves across. It may look like that is happening here, but I'll explain.
The triangle is first reflected along the line . Imaging putting a mirror on the x=0 line (the y axis, basically), and you'd see 1 to 2.
Then, it is rotated around the point . Get a bit of tracing paper, draw over 2, and then, holding the tracing paper down at (works well with a pencil), rotate it round and you will find it fits perfectly over 3.
Also is this the diagram?
