Well 1000 for his birthday then subtract 25 each week, w, should be 1000-25w if i am not mistaken.
The second salesperson is correct. The ratio is 1/16.
In order to find the correct ratio, you first have to turn the actual bridge length into feet. You do this by multiplying the yards by 3.
6 2/3 yards * 3 = 20 feet.
Now we can divide the painting length by the actual length to compare.
1.25ft / 20ft = 1/16
Answer:
Step-by-step explanation:
A(11, –2, –6) and B(–3, 7, –5) are located away from the origin (0,0,0), the points from the origin to this points is expressed as OB - OA where;
OB is the distance from the origin to the point B
OA is the distance from the origin to the point A
Using the formula for calculating distance between two points
OA = √(z2-z1)²+(y2-y1)²+(x2-x1)²
OA = √(-6-0)²+(-2-0)²+(11-0)²
OA = √(-6)²+(-2)²+(11)²
OA = √36+4+121
OA = √161
OA = 12.688
Similarly;
OB = √(-5-0)²+(7-0)²+(-3-0)²
OA = √(-5)²+(7)²+(-3)²
OA = √25+49+9
OA = √83
OA = 9.110
Distance from the origin to the points = 12.688 - 9.110 = 3.577
Distance from the origin to the points ≈ 3.6 (to the nearest tenth)
