Answer:
9530 cg
Step-by-step explanation:
P(2,55)
H(32, 15)
On the map, each unit represents 1 yard. To the nearest yard, what is the actual length of the land bridge from P to H?
A 50 yards
B. 150 yards
C. 78 yards
D. 234 yards
Answer:
A; the actual length of the land bridge from P to H is 50 yards
Step-by-step explanation:
Here in this case, given the coordinates of P and H, we want to calculate the actual length of the distance between the two points.
Mathematically, to calculate this distance, we make use of the distance formula;
D = √(x2-x1)^2 + (y2-y1)^2
In this case, (x1,y1) = (2,55) while (x2,y2) = (32,15)
Substituting these values
D = √(32-2)^2 + (15-55)^2
D = √(-30)^2 + (-40)^2
D = √(900 + 1600)
D = √(2,500)
D = 50 units
Now, we know that each units represent 1 yard, thus 50 units will represent 50 * 1 = 50 yards
Answer:
Step-by-step explanation:
Given : A pole 3 m high has a shadow 5 m long
The shadow of a nearby building is 110 m long.
To Find: How tall is the building?
Solution:
Let the height of building be x
A pole 3 m high has a shadow 5 m long
The shadow of a nearby building is 110 m long.
Height of pole and length of shadow has direct variation
