For question number one:
We know that in similar triangles, corresponding sides are proportional.
In this scenario we have two triangles- one made by a stop sign and a shadow and one by a tree and its shadow.
The side of the triangle that is represented by the shadow of the stop sign is proportional to the side of the larger triangle represented by the shadow of the tree.
Also, the side of the smaller triangle that is represented by the height of the stop sign is proportional to the side of the bigger triangle represented by the height of the tree.
Using this information we can conclude that 12/42=18/h
By cross multiplying: 12h=42(18)
solve for h: (42)(18)/(12)=h
calculate: h=63
The height of the tree is 63 ft.
Answer:
x = -5
Step-by-step explanation:
Divide each term by 4 and simplify.
Move all terms not containing X to the right side of the equation.
Divide each term by 3 and simplify.
So let's add variables according to the ratio:
3n + 2n = <span>£80
5n = </span><span>£80
n = 16
3(16):2(16)
48:32
Tom gets </span>£48, and Jerry gets <span>£32</span>
Answer:
are there options?
Step-by-step explanation:
They are congruent is the answer
