Answer:350
Step-by-step explanation:you multiply the amount of points which is 70 times the amount of targets which is 5 so it’s 70x5=350
Answer:
C. 27x-67
Step-by-step explanation:
To simplify, combine like terms meaning variable terms with variable terms and constants with constants.
81x-54x = 27x
-46-21=-46+-21=-67
The expression is 27x-67
Answer:
The height of the tree is is 60m
Step-by-step explanation:
Let's answer a, as it is the only complete question.
We know that the angle of elevation of the top of a tree observed from a point 60m away, is 45°.
We can model this with a triangle rectangle, a sketch of it can be seen below (assuming that you are looking it from the ground).
You can see that the adjacent cathetus to the 45° angle is equal to 60m
And the opposite cathetus is the measure we want to find.
Now you can remember the trigonometric relation:
tan(a) = (opposite cathetus)/(adjacent cathetus).
So to find the height of the tree we need to solve:
tan(45°) = H/60m
This is just:
tan(45°)*60m = H =60m
The height of the tree is is 60m
Answer:
20 miles
Step-by-step explanation:
I set this up as a linear equation:
45 + x = 25 + 2x
1. subtract x from both sides
45 = 25 + x
2. subtract 25 from both sides to isolate the variable
20 = x
