Answer:
-5x-4
Step-by-step explanation:
You first have to combine like terms. (-6x + x) + (+3 -7) = -5x-4
So assuming 1 3/4 feet by feet means 1 3/4 feet by 1 foot,
island actual dimentions=1 3/4 feet by 1 foot
scale=1 inch=1 feet
logically, blueprints are smaller so for every real foot, 1 inch is drawn on the scale
so change every foot to inch
so the island on the blueprint=1 3/4 inch by 1 inch
Answer:
Step-by-step explanation:
3³×6³×2³ = 3³×2³×6³ = (3×2)³×6³ = 6³×6³ = 6⁶
Place the compass on your first point.
then swing it to d or your 4th point
then with d as your center point and DE as your radius
draw an arc
keeping the same radius and E as your center point
draw an arc that will intersect first call that point F
and draw AF
Answer:
40.374 ft
Step-by-step explanation:
We assume that the height of the goal on the football field is <em>h </em>(ft)
As it can be seen, the height of the goal is equal to the total of the man's height and the length of AB.
=> h = 5.5 + AB
The triangle ABC in the figure is the right angled triangle with Angle B = 90 degree and BC = 10 ft
In a right triangle, we have the equation as following:
+) tan of an acute angle = length of opposite side/ length of the adjacent side
We have: Angle C = 74 is an acute angle, its opposite side is AB, adjacent side is BC
=> tan Angle C = AB/ BC
=> tan 74° = AB/ 10
=> AB = 10. tan 74° = 34.874 ft
=> h = 5.5 + AB =5.5 + 34.874 = 40.374 ft
